The pressing problems of how visualize our rapidly growing environmental footprint–and map the concept of a footprint over time–have found a new answer in the rendering of topographical and thematic layers to chart the degradation of forests world-wide. If deforestation is hard to get one’s mind around or grasp effectively, the tracking of the quickening pace of the loss of forested regions and indeed of the carbon sequestration that forests provide are elegantly tracked in a set of web maps that provide new cognitive tools to measure the effects of such abstract entities as globalization and free markets on the expanding losses of forested land.
Indeed, such interactive web-based maps provide something of a needed stimulus to the stewardship of intact forests, by offering ways to chart intact forest landscapes worldwide and survey anthropogenic disturbances in forested lands, and inviting analysis of existing forest cover, agricultural conversion, loss of forests to lumber, man-made fires, and industrial conversion, so as to render the planet’s surface area in newly readable form. While offering an interpretive surface unlike the symbolic forms or indexical referents of most existing GIS maps, the Google Maps base map offers a basis to render a uniform record of human activities on a rapidly shrinking range of forested lands–and the rapidly shrinking carbon storage intact forests provide. At a time when forest loss spiked in Russia and Canada, even as forest losses have grown worldwide, the map offers an exposé on forest management and best practices of conservation of forested lands, as well as a record of our global footprint in sites of carbon storage.

The ability to indicate forest losses with striking precision provides a welcome if unforeseen assistance from satellite surveillance whose data can help visualize the growing footprint of global forest loss. Although the necklace of satellites that necklace the earth are now more often associated with espionage of cell phone metadata, NASA satellites record the biomass of global forests by measurements that can construct a comprehensive muliti-dimensioned map of the balance between forest growth and loss. The zoomable map marry technology to ecology to chart a terrifyingly revealing record of incursions into natural resources worldwide, whose detail provides something closest to a tally of global lost and a record of the footprint of our globalized economy on the fragmentation of forests with a startling degree of accuracy. Remotely sensed data from MODIS satellites has allowed Global Forest Watch to bundle geolocated data for ready consultation by manipulating colorful detailed layers of an interactive map to visualize the effects of recent forest loss with an immediacy and precision not earlier possible.
The comprehensive interactive map of forest loss effectively materializes a global footprint in startlingly effective manner: for rather than merely mapping the amount of carbon emitted into the atmosphere in ways that reflect GDP, visualizing the scope of the depletion of forests–and of trees that offer reserves of carbon–suggests a true wake-up call by tracking the progressive effects of forest loss over a global expanse. The relative distribution of tree cover gain and loss can be readily scanned, beside the density of intact forests, or natural catastrophes, at a level of zoomable detail that stands as both a barometer and a chart of the unprecedented scale of forest degradation over the past fifteen years.
The extent of forest losses since 1960 have been estimated at over 180 million hectares, and the consequences of an estimated greatly diminished capacity to generate new forests of almost twice as many global hectares. The collation of a detailed map of forest degradation worldwide boggles the mind for its ability to comprehend the accentuation of forest loss in recent years, when inroads were made into the forested areas of Indonesia, Amazonia, and Central Africa–as well as the Canadian north–in increasingly rampant ways. The map Global Forest Watch has created and featured in their dynamically interactive website invites us to re-examine a global picture of forest change since 2000–of which North America is shown below as an example–translating big data into a set of actual traces and scarring of landscapes, marked by incursions of sensed biomass loss in bright magenta: at a time when the US federal government may auction off hundreds of millions of acres of national forest, wilderness areas, and refuges, projects the potentially disastrous consequences of sanctioning “increased resource production.” Whereas often classified satellites are better documented as creating a record of global surveillance, the remote sensing assembles a picture of the increasingly fragmented landscapes of forested land that suggests an often concealed inheritance of globalization, difficult to visualize or conceive on a global scale, that serves as a deeply monitory image of the growing global footprint that deforestation creates.
Does the footprint that these maps trace reveal a more complex dynamic of forest loss than earlier provided? Might the map offer new tools to understand the threats to the survival of not only old growth forests but intact forests worldwide? The image surely serves a somewhat stoic function for looking back, retrospectively, at the incursions into a planetary ability to store carbon worldwide, and of the dire lack of restraint and of the enforcement of policies of forest use.
1. Global disequilibria of legal forest harvesting and trade reflects a global difficulty to meet demand for wood. Structural imbalances are more often mapped as the consequences of population growth, as by Global Footprint Network:
National Footprint (2014), http://www.footprintnetwork.org
Yet the differences in the distribution of wood losses worldwide are not necessarily linked to wood market, but a wide range of potential reasons for the degradation of forested lands. Indeed, the problems of mapping both the expansion of agriculture and the illegal logging trade has created problems of accurate modeling of forest loss, in part due to the lack of an effective system of monitoring. The web-based maps of the Global Forest Network identify the world’s greatest exporters of wood–Canada, Brazil, and Russia–as not exclusively lying in sub-equatorial tropical rainforests, however, and indeed suggest the broad range of forested land that meets a demand for wood products worldwide–even as the demand has more than doubled since surpassing the biocapacity of forest land from the 1970s.
The intensification of deforestation has dramatically increased since 1995–the conventional date of the social effects of the globalization of markets from 1993-5, even if the process can be traced to earlier precedents, rather than 1492. As the need for carbon protection by forests has effectively surged, the pronounced patterns of forest loss reveal a lack of controls on forest loss, even at a time when we would require twice as many forests as exist to absorb the carbon emissions generated worldwide. How can such an expansive loss be fully comprehended? The layers that map wood losses in the Global Forest Network’s interactive visualization marks the extent to which we have pushed the ecological limits of incursions on forested lands, anthropogenically expanding the effects of natural fires or climatological disaster: the austere visualizations embody inroads in global forest-cover and intact forests, by tallying forest change by marking gain in blue and biomass loss in pink. The resulting pockmarked pink landscapes focuses viewers’ attention on the increasingly fragmented condition of forested lands, and raises big questions about their consequences. Indeed, it offers a definitive and geographically specific way to tally the results of the increased scarification of forested lands, linking the loss of forestsnot only to the extent to which high-income countries are expropriating natural resources of tropical lands, in Brazil or Central Africa, but the extent to which widespread practices of illegal logging has grown globally.
The suitably austere layers the map suggest a voracity of the fragmentation of many formerly intact forest, fed by demand for agrarian lands or lumber, in a form that gives a plastic and material evocation of the expanding losses of forest over time. The layers of the interactive web map effectively translate some very big data to create an image of lands are rent by natural and rising global demands, offering a new way to view the inhabited world or ecumene less in terms of sites of habitation or population, than map a loss of biomass that is almost elegiac in tone, despite its stark finality. Viewers are invited to scan interactive layers of the web map and take stock of the balance forest loss and growth over the earth since 2000, detect areas of deepest deprivation of tree-cover, and scrutinize the scale, scope and sheer size of forest loss to measure environmental change in an age of globalization. The Global Forest Network converts data to map the quickly expanding global footprint in forested lands, measuring the ecumene as it has rarely been seen and charting the fragility of forests in which we will now never walk.
The expansive and expanding degrees of degradation are difficult re cognitively quite difficult to contemplate or process. But the spatial collation of disruptions on local habitats creates a new sense of the readability of the map and of attending to the widespread degradation of forested lands that seem an unnoticed–and somewhat elusive–counterpart to the growing globalization of the demand for wood and for agricultural land, by mapping the disappearance not only of habitat but of wooded lands–and even providing tools for actively engaging with a rapidly changing world.
2. Cartographers have long worked to render a “mathematical figure of the earth” viewers could readily scan, translating spatial distributions to accurate formats despite the multiple and inevitable distortions of any map and wresting with questions of accuracy. Interactive visualization wizards of web maps showcase distributions by a spectrum that filters experience in multiple layers: visualization wizards seem particularly apt tools of responding to problems of embodying data trends–and ffiltering data to generate images which embody exact distributions of forest degradation along roads, rivers, in regions of timber harvesting, and even in currently protected areas. The maps of forest loss provide a record of future archeology of the anthropocene, akin to maps of temperature change or of our overheating world.
The destruction of some 250 million acres of forest since 2000 by human development threatens to bring the fragmentation of forests, compromising not only integrity of ecosystems, animal habitats, and tropical rainforest, as well as increasing erosion, but the sequestration of carbon in ways that have irreversible impact on the planet. We see the world with new eyes by measuring the extent of timber lost by something that approaches real-time measurement in the dramatic amps the World Resources Institute and Global Forest Watch have created online. Although satellite measurements more often identified with surveillance, the high radiometric sensitivity are able to pinpoint a record of biomass loss across the world’s forested lands that set new standards for a running-time comprehensive map for charting the distribution of dramatic losses of forested land–similarly to the detection of forest fires–in an increasingly expansive and loosely regulated market for wood. Even without describing or identifying the causes of forests’ fragmentation, the layers of the web map offer an almost inevitable and irreparable image of the scope of forest loss even in protected lands.

The collation of growing forest loss within these maps raise questions about the sustainable practices in forest regions aptly characterized as the planet’s lungs. Ten million sq km of forested land have been estimated to have been cleared between 1890 and 1980: a further 500,000 square miles of lost heavily forested land were lost since the year 2000 that can be watched in stop-action accelerated real time in the web maps that display forest data, by geotracking the loss of a further million sq km of intact forest through 2013, in a sort of stop-action map that includes Indonesian forest fires, land clearance in Brazil and the Amazon, and the increased commerce in wood and forestry in Canada, Honduras, Indonesia, and much of South East Asia that seem an inexorable result of a voracious market for wood in a globalized economy.
As well as documenting the loss of some 8% of the economy since 2000, Global Forest Watch has embodied remotely sensed data in dramatic and disquieting to map the ongoing fragmentation of forested lands in a time-lapse map of some thirteen years–mapping the surface of the earth at a time when the range of anthropogenic incursions into forested lands, and the planet’s history, rapidly grew provoking discontinuities in previously intact forests and forested habitats of which we are only beginning to take stock, and whose disruptions threaten to radically change the planet’s lived geography. The layers of forest change that are distinguished in the interactive web maps the Global Forest network devised present a color-coded basis to gauge the incursions into forested lands of the world by human industry and economy as well as fire. They offer an image that is both the tabulation of a benchmark and a memory map that reminds us of the loss of forested land over thirteen years which is a cautionary note about the need for better stewardship of forested lands in a globalized economy–and, indeed, those sites that are most intensely aggrieved in the modern age.
3. In a less frequently cited monuments of cameralist thought, Saxony’s Chief Inspector of Mining, Hans Carl von Carlowitz described forms of the conservation and cultivation of native trees where his family had long run mines; the Sylvicultura Oeconomica which in 1713 perceptively responded to fears of a shortage of wood after the Thirty Years War, to benefit the common good by advocating sustainable practices of forestry. Nachhaltende Nutzung provide a set of responsible practices, or “a blueprint for the guiding principle of our time,” and something of an early recognition of the intentional planning of practices for the conservation of wood “for posterity” that we might look to at a time when the fragmentation of intact forest rapidly grows, as the remote registration of the distribution of decreasing forest biomass detected remotely by MODIS satellites reveal that go beyond the sort of aerial photos of forest degradation below seen in the Rondonia in Brazil over a mere six years.
Although the reasons for the degradation of forests due to alternative anthropogenic causes–land conversion; timber extraction; degradation of land–is not clearly distinguished from loss of forests to fire or catastrophe, individual layers allow the reader to distinguish between potential factors that precipitate forest lost, and uncover varied reasons for the growing crisis in sustainability of forests worldwide, as technology provides a useful medium to measure effects on the natural world. The dynamic qualities of static maps is enhanced by suggestive chromatic variations, the ability of LandSat 8 to create a remotely-sensed picture of the world in but sixteen days allows dynamic records of land change to offer the chance of intensive reading and investigation not earlier possible. While the causes of wood loss cannot be clearly discriminated, to be sure, the layering of maps provides a basis to take stock of the extent and locations of wood loss. The layers of web-based maps invite viewers to investigate multiple potential narratives about the shifting ecosystems in a rapidly changing world. The layers of the map suggest a new way to embody data to view its palpable effects. By importing data that they open or stake directly on the surface of a map or spatial database,web-based mapping offer a supple interactive medium to situate narratives in a global expanse–from situating the relative geographic densities of sightings of hummingbirds–
to relative geographical variations of biodiversity–
Remote sensing of incursions into intact layers of tree cover by Modis satellites provide an even more sensitive tool to display data of habitat change and ecosystems alike, and indeed to trace the incursions of a clandestine economy of wood on areas of forest that remain threatened, from clearing for agricultural areas, prospecting for palm oil, chainsaw logging, or bring of peat. For remote sensing can record at startlingly high resolution disturbing incursions, breaks and absences in forest expanse and the distribution of intact forest and tree cover at the considerably high resolution of thirty meters, creating a tragically compelling record of anthopogenic disturbances of subtropical and other forested lands regions that comprise some 37.3% of the world’s total land area.
The record stands in inverse negative image of the expanding consumption of wood in the world’s more populated areas, and sets something of a watermark in the growing dangers of the apparent lack of oversight of the global consumption of wood. The stacking of layers of data reveals a particularly striking record of natural degradation and loss of forests, that details the increasing intrusions into intact forests and tree cover worldwide in ways that suggest the continued value of synthesizing an almost pictorially present record of our increasingly poor management of the valued resource of forested lands–both for the species who live in them and the biodiversity they nourish, as well as the atmosphere they help preserve. These losses are materialized in especially compelling graphic terms in renderings of the comprehensive record of the incursions of lands that have created a steep loss of wooded biomass.

The colored layering of data in the web maps devised for Global Forest Watch create a legible balance sheet for accurate viewing the disappearance of forested lands, coloring tree cover gain and loss at an amazingly exact resolution of up to thirty meters. The cartographical accounting of tree cover loss–and forest degradation–for viewers to begin to process and come to terms, balancing magenta losses of biomass with planting of new trees in deep blue.
The global purview of this data Global Forest Watch is effectively rendered in CartoDB offers a point of entrance to a dramatic narrative of loss. The mapping of forest loss can be measured against the globalization of an economy for wood that knows relatively few restraints, creating a compelling visualization on scenes of clear-cutting that might otherwise leave their viewer speechless.

4. Globalization increasingly forces us to try to conceive as well as calculate the steep variations in the consumption and use of resources worldwide. The increased variations–and variability–in geographical description of how we consume resources suggests the need for new ways to imagine geographic space that foreground its alteration that reveal the huge losses of biomass worldwide over time with a precision that sets new notions for the accuracy and possibilities for the persuasive powers of maps as images. The charting of the lost biomass of forested lands creates a constructive relation of tragic narrative of loss, to be sure, using thematic maps of the physical changes in the global landscape to direct attention to a range of narratives of loss, and alert us to multiple possible narratives of both loss and potential ways of averting impending future losses by rendering visible the loss of forests and invite investigation of their causes and origins. If in many ways the history of the most recent periods is both hardest to tell and to try to comprehend, the multiple thematic maps of tree cover loss highlight the changing landscape of tree cover and carbon stock–and the threats to intact forests that wood use poses–that provide an investigative tool to examine the emerging threats to intact tropical forests and wooded ecosystems in ways that viewers can visually process and cognitively digest.
For the totality of forest loss that the interactive thematic maps of the Global Forest Watch synthesize and render reveal a record of intersecting ecosystems that foreground questions of the continuity, density, and loss of connectivity in forested lands that raises serious questions of concern about their increased fragmentation. By providing a global synthesis about the use, degradation, and replanting of forested areas and trees worldwide, the tally of global biomass that they reveal provide an elegantly color-coded record of the limits of sustainability of our forests. The sustained silence about the contribution of the destruction of worldwide forests to the release of greenhouse gasses in the planet is a deep deception that the illusion of the limitless potential for the expansion of a market for wood and wood products perpetuates in a particularly insidious way. The global thematic maps of remotely sensed presence of wood and forest density in a remarkably accurate manner provide a necessary corrective.
By revealing the loss of forest cover and the fragmentation of forested lands in a zoomable fashion, the thematic maps invite not only reflection on a tragic narrative of the memory of loss–as they do–but might perhaps incite similarly global strategies of protection and conservation, helping to ken the steep risks that globalization portends to the possibility of a truly sustainable future. At a time when industry increasingly rests extracts revenues in whatever ways possible, the sacrifice of forest lands demands increasing attention.
Global Forest Network has opportunely responded to the need for mapping a totality of forest degradation by assembling a remotely registered image of the scope and extent of biomass loss in forests worldwide. By mapping an effective tally of trees planted and forested land lost over time in a time-lapse fashion, one can visualize the unsustainable rhythm of an all too rapidly growing footprint of the loss not only of habitat but of reginos that might be called the planet’s lungs. Their web-based maps reveal offer indices and tools to reflect on the impact of globalization on forested lands. The 2013 map of the shrinking forests of the world sensed remotely from 2000 to 2012 used the first high-res comprehensive global map of forest degradation to craft an alarming story by directing detailed attention to the question of costs: synthesizing 654,178 individual images to model human and natural forest loss, the result is a persuasive record of human geography, delineated in the rich color palette of CartoDB, inspired on one devised by Cynthia Brewer: losses of forest are strikingly rendered hot pink to purplish magenta, fire red-orange, tree-cover pea-green against intact forest rendered a rich kelly green. Rather than retain national boundaries as the prime units to parse ecological change and man’s impact on the environment, these maps of the sustainability of forested lands provide multiple layers to examine the use of wood worldwide–and contemplate the ecological and economic implications of a huge reduction of over 500,000 square miles of formerly healthy forests by for the first time charting the local loss of forests in an accurate and globally consistent manner–conspicuously marking variations in land use in a year-by-year distribution, discriminating between forest land lost and gained to shine a lens on the question of the sustainability of forests and the fragmentation of forests, tracing the expansion of our carbon footprint through the ongoing scope of forest degradation and loss that has expanded with a demand for wood worldwide with major risks to the surrounding environment.
The survival of a coherent network of forested land is a central to the survival of ecosystems, and to local livelihoods of a large range of humans, as well as to the global storage of carbon in the ecosphere: the hugely negative effects of forest degradation stand to contribute to upwards of a fifth of carbon emissions, as well as to have disastrous effects of animal habitat and local ecosystems and biodiversity, and an image of the loss of forest cover and the fragmentation of formerly intact forests provides a compelling record of human-made and natural incursions into wooded lands from 2000-2013, revealing the uneven distribution of the exploitation of forested lands in a globalized economy. Although the largest regions of intact forest are located in Tropical and Subtropical Forests (45.3%) and Boreal Forests (43.8%), and almost 64% are located in Canada, Russia or Brazil, they face distinctly different challenges of industrial logging, oil and gas extraction, and natural clearing: even without distinguishing patterns of land use, the maps suggest the incursions of human influences on these and other particularly fragile forested landscapes, in ways that trace a narrative of the distribution of forest losses in the new millennium, and more importantly the balance between forest loss and gain.
If the loss of forests truly accounts for more than the sum total of carbon emissions of all cars, trucks, planes, and ships every year, and create a more compelling way to combat climate change, as well as acting to purify air, preserve watersheds, and foster biodiversity, and prevent impending dangers of erosion, the shrinking area of forested land provides a particularly sensitive barometer that demands to be on the global consciousness and a site for restraining consumption. Indeed, once stewardship of forests are included within measures of carbon emissions, tropical rainforest-rich countries like Brazil and Indonesia–both growing economies, to be sure–jump into the group of the top ten global polluters–a fact concealed by the expansive international market for wood.
Rather than only measure the metrics of forest loss, the rates of forest degradation in different areas create an interesting record of the inequities and incursions into forested lands, which has striking parallels to the disappearance and lack of protection of community land-rights in the face of economic demand. How to calibrate the role of pollution that results from forest degradation? The layered web maps raise the possibility of tally that could lead to better stewardship of forests, and pose a call to manage “carbon stocks” of which we have few comparably accurate measures. The maps offer a quite significant key to curb global greenhouse gas emissions, indeed, by charting the threats to carbon stock of sensitive areas from tropical forests–from the Amazon to central Africa from Equatorial Guinea to Rwanda and to Indonesia–to North America, by visually highlighting the balance of intact woodlands unlike a static map, by conspicuously marking loss of woodlands in pink/magenta and using orange to note carbon stock threatened by tree-cover loss to trace the all too human incursions in the tropical forests, balanced against the scattered tree-cover gain noted by periwinkle blue.
The result is to make the land speak in an almost palpable way by inserting crucial layers to map the shrinking landscapes of intact forest, continuity in tree-cover extent, and note protected regions, biodiversity hotspots, current fires, and regions used for logging, mining, or wood fiber plantations, so that we can, even with the introduction of only a few layers, sense the risks to forests in Amazonia or Indonesia that are particularly sensitive to globalized markets for wood. 
One can as easily add a layer revealing the primary forest of Indonesia that maps the extent of its coherence, and allows continued depletion of forested lands in the region to be read in relation to its most densely forested regions, beside the depletion of forests in the Philippines, Taiwan, Thailand and Papua New Guinea: 
The result is a brilliant visualization able to mediate the concept of sustainability in its multiple layers. The idea of such a comprehensive map of forests derive from synthesizing the MODIS images on a Google Earth engine to trace the contours of such a footprint. They can be read interactively by adding, removing, or toggling between specific layers displaying the ever-shrinking quantity of “intact forest landscapes”–regions untouched by human economic activity, settlements or industry of 500 sq km without evidence of habitat fragmentation, regions distinguished by tree loss or gain, and regional tree cover. Although much wood and fiber has concentrated on economic value rather than ecological effects, the interactive map brilliantly illuminates the changing contours of forest landscapes worldwide, including land-use change, log forests sawn for lumber, fires, and clearcutting over time that provide a baseline for stewardship and management, revealing the extent and nature of the loss of forest extent in South America and sub-Saharan Africa. Global Forest Watch has assembled stunning interactive web maps that invite readers to investigate the relative imprints in each region over twelve years, creating a valuable historical document of deeply monitory functions, if as well as a stunning record of historical change on a global scale.
The significant role of forest in contributing to the livelihood of over a billion of the world’s the poorest dwellers suggest the economic as well as ecological imperative of restricting losses that would be impossible, if not difficulty, to ever recuperate or restore.

The geographical remoteness of many vulnerable areas of forestry creates a clear need for the globalized mapping of forest loss–if only to offer a needed corrective to the globalized market for commodified wood, which enters markets with almost no sense or measure of its site of origin, and with few reports of the degradation of forested lands that result in such particularly sensitive ecosystems in tropical forests. The interactive web maps may address the considerable alienation of most commodities markets–or even markets for wood and wood-products–from the very habitats and ecosystems that forests create, and the levels of unsustainability of the current market for often indiscriminately forested wood and wood-products. Indeed, many early modern maps reveal the situated nature of local interdependency between peoples and forested lands–and the commerce with wooded lands–that is so often abstracted from market of wood, characterized as they are by the relative alienation of patterns of consumption from the survival of forests.
5. The sensitivity of early modern notations of forested areas nicely suggests something like a need to change our practices of global mapping to track the interdependence of urban economies and patterns of consumption on forests that are increasingly far flung rather than surround our lived environments, or the absence of a clear sense of forested areas as rich resources of life and commerce on which a built city–such as this image of the merchant city of Nuremberg, drawn and painted on linen by its own early sixteenth-century surveyor, Erhard Etzlaub, which suggests a particularly complex understanding of forest management and use in depicting the considerable levels of forest density proudly preserved around Nuremberg.

The relative absence of maps that effectively preserved an affective record of forest loss has been designed to meet the hugely magnified loss of forests worldwide, and especially in equatorial regions where they seem to have fallen prey to a growing global hunger for consuming wood that cannot be easily sustained. The series of zoomable maps offer an invaluable basis and provocation to reflect on the virtues of data and the limits of best rendering data in visual form. More specifically, they provide a basis to use maps as a tool to model the levels of sustainability that exist in forests worldwide, by the actual mapping of both forest loss and forest degradation worldwide that has been increasingly conceived as the growing ecological footprint created through a decline of worldwide forests that have never been able to be satisfactorily visualized or conceived of in their totality.
6. The Canadian economist William Rees introduced the conception of ascertaining the impact humans exercise over natural surroundings as a “footprint”–using a term developed by his student Matthis Wackernagel with him in hopes to conceptualize the undeniable traces that they left on the environments in which they live, by analogy to the “footprint” of a computer resting on a workplace desk. The rapidly accepted currency and quick adoption of the term was striking. Its ready adoption reveals apprehension of an unsustainable set of practices to consume resources that exceeded natural abilities for their replenishment, long before the archeological definite that led our own age to be described as the anthropocene. Although Rees introduced the term of a “footprint” predominantly as a conceptual tool, it has also begged visualization due to its concreteness, and ready connotation as a tangible record of impact–and as such demands to be mapped–it has often been taken too literally as a guide to creating data visualizations.
The linking of levels of emissions to the lifestyles of residents of individual countries is telling, but risks the sense of reminding one of the difficulty of changing differences of consumption as if they were an inevitable cultural choice–and have the odd consequence of removing the figure of speech of the “footprint” from a logic of sustainability, in this image of Stanford Kay, which relies on a bubble map to pose a charge to the most popular polluters, but tends to obscure the scale of the question and its possible impact on the world–the rainbow colors allow us to parse the relation of pollution to continents to some extent, but make it truly difficult to assemble a picture of sustainability, or of the global consequences of the expanding carbon footprint of the earth’s inhabitants. While we don’t doubt that China creates the largest carbon emissions in Asia, what measures of sustainability need to be taken or could be proposed? Need we only accept the habits of consumption adapted in the world’s most populous nations or can we curb them? 
Stanford Kay
A static if cumulative atlas of carbon emissions was produced by the Energy Information Administration and ran in The Guardian in 2011, in the form of an actual terrestrial map, which charted both the relative contribution of countries to the global footprint in the millions of tonnes of carbon emissions it generates, and a notation of their relative augmentation or decrease in 2008-9: the infographic provide a document used as something of a running tally of CO2 emissions per country, as a way to measure the reduction of emissions agreed as a goal at the Kyoto protocol, and was imaged by artists Mark McCormick and Paul Scruton of the world’s distribution (available as a PDF file) that took a traditional terrestrial map as an alternative visualization of the greatest emissions by continent–and laying the blame at the doorstep of specific countries.
The Guardian
Chuluun Togtokh of Ulaanbaatar invested considerable forcefulness to similar statistics in a pointedly polemic manner when he effectively retabulated a the levels of countries’ levels of sustainability in a brilliant revisionary cartography, including control of carbon emissions within what constitutes the United Nations’ Human Development Index–a metric synthesizing life-expectancy, literacy and purchasing power–but which omits sustainable growth as a relevant criteria of development: by reminding readers of the ethical imperative to cease ignoring the costs of the greatest polluters in the world, lest we fear to acknowledge the ever-steeper competition for dwindling resources that “growth” perpetuates, Togtokh’s measurements present the ability to remap the question of “economic development” in ways that include environmental stewardship as a criteria:
As vice-chair of Mongolian IGBP Global Change National Committee, Togtokh chastised as much as reminded the UN and other international agencies of the folly of ignoring sustainability or carbon footprints in calculation development. The map reveals the importance of what data we include in the map, and what story we decide to make it tell. The visualizations of forest loss provide a far more finely grained story of carbon emissions, less artificially flattened along national lines, and focusses on one variable in need of urgent response. And at a time when humanity’s demand on nature exceeds natural resources by twice, such footprints might be more compellingly visualized and communicated. Forest degradation provides a particularly relevant index of global impact, both a record of compromised carbon storage and since the destruction of biomass in land-use change creates a massive 17-29% of global greenhouse gas emissions and irremediable loss of habitat for vertebrate animals.
7. The vivid contrast between geolocated data within the interactive web maps create a dynamic panorama that tally tree loss to reveal an actual imprint of the human economy on deforested lands–far beyond what it was during the entire twentieth century due to new techniques of clear-cutting.

The global and regional maps parse local data changes in the size, fragmentation, and density of forests over different periods of time that provide a crucially informative tool to examine the rapid pace of our apparent losses and rabid degradation of forested lands–losses of which many, if not most, are blithely unaware.
The striking coloration of the interactive map jointly charts the diminution and growth arboreal expanse worldwide to alert viewers to the impact of the footprint of forest loss and clearings. In ways that are easily apprehended, bright colored magenta pink call attention to the relative loss of forests in different areas that one can scrutinize in zoomable fashion, to generate legible maps that show forest degradation that convert available data with a precision that seems almost instinctively legible far more dynamic and more legible than a bubble map that is abstracted from the land. The zoomable record of terrain allows one to track the points of forest loss against intact forests in such disparate regions as Amazonia or around Lake Victoria in the Congo or the Northwest Territories, tracking the extent to which such loss outstrips any areas of forest gain (highlighted in periwinkle blue) and allows one to observe the intensity of loss across land. Even if they include few words, the variability of color and hue provide a case where the land speaks, and the cumulative loss of tree-cover can be examined in detail across borders, and over a twelve-year period of time in which the forces of globalization have made their impact felt worldwide:
And to observe the scale of the “footprint” at a considerable high resolution, taking into account the losses of tree cover that are registered in relation to the areas of “intact forest landscape” that is registered in dark kelly green, with small areas of forest growth noted in periwinkle blue, in ways that synthesize a record that shows the degrees to which tree loss is exceeding the capacities of local ecosystems that may be particularly fragile indeed, and forever transfigured:
Weirdly predictable patterns of tree loss line what seem to be rivers that run into older intact forests in the Central African Republic:
The areas devoted to lumbering across the Northwest Territories can be noted in an overlay of tan, setting it off from the areas of considerable tree cover loss that are relatively widespread within it, but spread with a terrifying concentration of clustering in areas of intact forest landscape as well:
The very visibility of a footprint in these satellite maps materialize the concept of a sustainable footprint that Mathis Wackernagel first developed, and is associate with both Wackernagel and his teacher Rees as a fundamental critical tool of ecological economics. The recent definition of “intact forest landscape” provides a crucial parameter by which the maps invest materiality in the notion of a “footprint” which build upon desires for sustainability, and a mapping construct that allows one to ascertain and observe forest degradation in new ways, and indeed the extent to which most industrialized countries have far outstripped their “carrying capacity” of their lands.
Indeed, the problems of sustainability have been deeply exacerbated by globalized trade that Rees and Wackernagel’s demand to reduce our ecological footprint–too readily directed at a few nations, rather than recognized as important as a global imperative–demands an ability to confront the problem of ecological overshoot that would have as its most obviously persuasive source the form of a world map whose uniform distribution allows us to target the biomass in need of protection.
It is striking, however, that if the notion of a “footprint” provides a reflective tool to take consciousness of outstripping global resources, it has been widely adapted in ways that almost excavate it of the attention to ecosystems. Most recently, the notion of the “footprint” has enjoyed far wider currency as a cartographic conceit, diluting its original intent in an almost comic turn, when adopted by the US Department of Defense in 2008 to illustrate the global dominance of the presence of military forces over an unprecedentedly far-flung portion of the globe, in an apparently odd appropriation warping Rees’ original intent.
If one feels need for taking break from the depressing metaphorical use of footprints global and military, a nicer appropriation of the footprint lies in how vineyard-owner Bonnie Harvey decided in 1968 to include her personal footprint as the playful logo to evoke the stamping of a grape harvest, before the widespread adoption of Wackernagel’s phrase–in this “wet” footprint, if its connotations of local eating carry far more self-satisfied semantics of the California coast–albeit in ways that are now marketed by Gallo wines–as well as a sponsor of fun-runs across the state, playing on the image of the former tradition of treading grapes in vats by foot to extract their juice in annual crushings:
With the sort of untrammeled demand for commodities and consumption that has led us to double the Gross World Product in less than twenty years, driven not only by population growth but a rapid expansion of per capita energy expenditure, the importance of acknowledging and recognizing the accelerated appropriation of global resources and natural capital seems increasingly tied to crafting such an “ecological footprint” analysis in adequately persuasive terms. Yet it is reassuring that the growing footprint of the globalized economy on forest worldwide have encouraged the adoption in Canada of a Plan Nord, in which the same government often challenged for protecting foresting rights has promised to protect some 50% of the forested land above the 49th parallel in the province of Quebec, in a major accord to protect intact forests in the northern part of the country from mining, industry, lumber and development, that commitment to conservation that provides a possible basis for similar program of protecting forests in the Northwest Territories, and much of the world. 
8. The peculiar construction of the maps of forest degradation prepare a record invites examination through the concept of a “footprint” as both a metaphor and figure of speech implying an ecological balancing act. If Longfellow described the hope to “leave behind us/ Footprints on the sands of time” able to inspire exemplaric lives that “can make our lives sublime,” the maps of dramatically diminishing forest-cover detail a threat that, while the public commentator and self-styled linguist William Safire once disdained this apparent “March of the Metaphoric Footprints” as a migration of meaning that seemed sloppy in its claims, and Safire, although long pro-corporate, may have been upset by the ready currency that it gave a metaphor which barely indicated the scale of its actual impact and, even moreso, the notion that an Emersonian image of untampered nature that “shines into the eye and heart” to create a “perfect exhilaration” was far from what Safire sought it worth the time to preserve.
But the incommensurability of the image might have been a large part of the problem for the New York Times pedant. The conceptual tool of Rees and Wackernagel, however, did not build on the notion of the “virgin land” and “untrammeled” landscapes as free from human impact, pace Howard Zahniser, as would be evident in not leaving evidence or footprints from a visit, but to suggest a recognition of just how great such footprints could be. Wackernagel adopted the more pedestrian metaphor of the spatial footprint that a computer left on a desk, to suggest an empirical index and analytical tool that could be quantified. The economics of ecological footprints provides less a figurative than an analytic tool, able to be identified and measured by global hectares, rather than by marks in the sand, and measured against the biocapacity of the earth, and a question of the consciousness of individual impacts on the environments in which one lives. As Togtokh calculated, the footprint seemed to decisively grow in countries where levels of consumption seem so widespread to outstrip consciousness of environmental impact.
Emerson imagined the glory of nature from a subjective position, “my head bathed by the blithe air, and uplifted into infinite space,” as triggering a place where “all mean egotism vanishes: and “the currents of the Universal Being circulate through me; I am part or particle of God” in a transcendent moment, where in the “line of the horizon, man beholds somewhat as beautiful as his own nature,” the notion of an ecological footprint returns to the material dependence of man on nature. How to map that dependence, and describe the amount of land required to support a person, and indeed the ecological footprints of economies, and the appropriation of land in each, poses a question that the MODIS satellite images help map in a cognitively persuasive fashion.
It is hard to see how such an ecological impact could be adequately visualized or grasped. Safire may have been intentionally obtuse in pooh-poohing the footprint’s use as a figure of speech. Wackernagel and Rees strove to indicate the impact humans exercise on the environment, the image of an idyllic erasure of egotism and uplifting to infinite space was less the aesthetic than a hope to minimize the impact of human activity on the landscapes. The constraints or limits on hopes for sustainability have often been charged, based on data of national policy, as a failure of ecological responsibility, or of running against the limits of what is able to be sustained by natural resources: and the sensitivity of the biomass of forests as a reserve of CO2 provides a uniquely tangible instance of such a national responsibility. While often not included in the maps we make of carbon emissions, which distinguish countries by directly translating data of million metric tonnage of carbon produced–the map’s tones suggest a scolding of lifestyle, habits or inefficient policy controls, but fail to render the emission-levels in tools of critical response. Indeed, most maps root emissions them in levels of industrial production and population density that provide limited possibilities of being grasped save in a very broad sense of differences of lifestyle or something so broad as if it were a cultural choice in consumption patterns. 
University of Wisconsin Cartography Lab
The alternative of parsing data in slightly more sophisticated manners on a scale of sustainability can foreground surpassing an threshold of biological capacity of local resources, alerting us to where the planet exceeds its biocapacity in hectares, which shows, again, the concentration of populations within those areas that individual consumption exceeds the biocapacity of regions, creating a heuristic tool to understand the inadequate relation of markets to levels of natural goods worldwide.
Global Footprint Network–Wikipedia
9. Although there is some value in giving a embodied form to Wackernagle’s metaphor for measuring the regional release of gaseous emissions and carbons in the popular infographic of Stanford Kay’s Information Graphics Studio, intended for the international edition of Newsweek, but popularized in the Atlantic, the foot-shaped bubble map metaphorically removes the “footprint” from measuring environmental impact on the globe. It seems a playful reference to the measurement of gasseous emissions, able to be perused to note the extent of the problem, but not to communicate the impact of emissions on the world–and hence perhaps of more elegance than either hortatory or monitory value.
Kay’s quite colorful mapping of carbon emissions quite unsurprisingly located the most populous nations as the greatest emitters–China is at the ball of the foot and the United States as its heel. A complimentary view of per capita emissions instructively altered the picture a bit–suddenly, the Virgin Islands appear at the foot’s ball, and not the populous United States.
Despite the infographics’ elegance, does there remain a risk that such a statistical distribution of emissions distracts us from the changes that globalization has wrought in our environment, and the drastic degradations of the forests that are themselves the consequence of such elevated levels of consumption? And does it detract from the degree to which the destruction of biomass and carbon storage provides an equally looming biological danger, of proportions that we have not been able to fully grasp? Indeed, by revealing the shared nature of what remain common problems of the loss of carbon storage worldwide–and animal habitat–the map departs from a nation-by-nation mapping of dangers, in ways that might seem to inherit nineteenth or twentieth century classifications incommensurate with a problem of truly global proportions of the loss of biomass, by spacing and ordering of uniquely obtained data of forest loss that the viewer can readily grasp, rather than being forced to confront in all its monolithic immensity. The problem is one of organizing data in a suitably readable form.
For such powerfully damning visualizations, while embodying a footprint, often remain quite disembodied from the nature of the losses of resources or generation of waste that they imply, and ask whether the display of data is enough: the limitations on engaging with the maps suggest that the display of data is so overwhelming to ifrustrate or press against the limits of representation, and discounts the effectiveness of how meaning can concretized in maps that direct attention to the disappearance of resources and the alterations of carbon footprints on the land. The detail of the Global Forest Watch web map is brilliant in the ability to investigate a uniform global standard for accelerating degradation that help us grasp meaning in all the mess, in ways that almost make one start to think good things about Google Earth, as surprising as that might be.
10. The image of loss of forested lands–and loss of trees–provides a concise statement of the growth of our collective carbon footprint. Although one continues to wonder whether data is enough to represent the compromise of the biosphere, or how global footprints can be more crisply visualized than the bubble maps of carbon footprints, the loss of lumber is revealed with indelible accuracy on these maps’ face that make them more readily graspable, their content most cognitively persuasive and suitably compelling in impact to impel viewers to navigate local details in their surface: the distribution of data in this map is rendered more transparent and uniquely able to preserve a sense of local impact in less disembodied manner. The below distribution indeed concretizes the local lossses of tree-cover that MODIS has registered over twelve years–or from 2001 to 2012–in ways that remind us of the reduction of tree cover over that decade not only in the American south or shores of Mexico, but in much of California, Washington, and Oregon, and across British Columbia with a texture difficult not to admire. 
Global Forest Watch By the insertion of layers, the map’s snapshots of the earth’s surface can be investigated by drop-down menus, allowing one to map tree loss across regions of intact forests or tree cover, to calibrate the nature and consequences within a picture of existing treecover loss in, say, California:

11. The huge value of the dynamic cartographic synthesis by Google Earth Engine lies in the comprehensiveness and accuracy with which it allows us to start to comprehend forest loss. Indeed, elegant search functions allow users to detect, despite some questions that could be raised about the ability of the MODIS satellite to detect lighter forests and brush, rapidly advancing variations in forest-loss worldwide. The visualization allows one to scrutinize the relative extent of the forest cover’s local degradations worldwide and over time: the amassing of this data on a Google Earth Engine was achieved in several days that offered both a compelling advertisement for its readiness to process geospatial data, and the possibility of modeling the relative intensity of losses of forest land in a brightly vivid dayglo green, creating a compelling graphic that testifies to the depletion of forested lands worldwide that clearly coincides with globalization: indeed, the comprehensive tracking of the lost of forests in fluorescent green areas from Malaysia and Indonesia to the Congo and Brazil, and from Cambodia to Russia to Central America and northern Canada reveals substantial clearance of forests, independent if linked to forest fires and protected forestland.
The layering of degrees of forest loss moreover creates a compellingly synthetic record of land-use. 
World Resource Institute The chromatic variations among our shrinking forests worldwide was remapped to model the loss of tree cover worldwide from 2000-12, courtesy the World Resource Institute, is perhaps more shocking–and more easy to know how to respond to–than global warming. The illustration of a loss of tree cover since the year 2000, which has doubtless progressed far more extensively since, suggests something like a plague of deforestation, which far outweighs tree cover gain in the same period–over this period, the loss of 2.3 million square kilometers constitutes something like an atrophying of the forestlands worldwide, approximated by the WRI to equal the disappearance of some fifty soccer fields of forest each and every minute of every day, for long over a decade, at the same time as only .8 million square kilometers of forest was replanted.
If by 2005, about 30% of the land on earth was covered by forest, just under four billion hectares, the increasing loss and degradation of forests poses an ongoing challenge. The data reveals what is happening to the world’s forests in a globalized economy. If the amount of energy expended on clearing forests alone has been estimated to constitute between 12-20% of global greenhouse gas emissions between 2000 and 2012, the storage of carbon in forests–and the forest’s value as a source of economic livelihood–are both threatened by the dangers of deforestation worldwide. The detailed interactive map that was produced by real-time feeds of a MODIS satellite and synthesized by a Google Earth engine combines sensed layers of forest depletion over time to create a suitably sensitive platform to monitor forested land, using work of Matthew Hansen of the University of Maryland to map forest cover in that suggests a dramatically new way that we might understand and comprehend the effects of globalization on our concepts of the inhabited world, by toggling back and forth on a sliding bar to reveal the scope and scale of forest depletion from 2000 to 2013. The data is striking–but is it ever enough as an effective embodiment of the scale or varied concentrations of such an expansive loss of biomass?
Forest Loss World-Wide (Global Forest Watch)
To an extent, the maps of tree loss that were created by the Global Forest Watch, a partner of the University of Maryland, use satellite readings to refine the forest/non-forest global mosaic that the Japanese Aerospace Exploration Agency (JAXA) assembled from Aperture Radar aboard the Advanced Land Observing Satellite DAICHI. The composite imaging of an accurate global distributions of forested land, at a resolution within ten meters, called attention to the degree to which forest degradation increased CO2 emissions created for a 2010 summit of the Group on Earth Observation in Beijing that set a new standard in remotely observed calibration of earth cover that starkly foregrounded threatened areas.
The unprecedented resolution of these images created a compelling watermark for future forest loss, and directed attention to deforestation that provoked the United Nations to declare 2011 as the Year of the Forests that celebrated heroes of local land management. The layering of measurements of forest loss over time in the MODIS maps offered a comprehensively view the effects of forest loss and view tree loss over time. What can explain such a radical augmentation of deforestation, concentrated in relatively specific areas? Despite the improving curbs on forest loss in Brazil, for example, the deep increases in forest losses in Indonesia, Cambodia, and Malaysia, as well as Paraguay and Bolivia, offset any gains across the earth, and suggest a lack of orientation toward conservation or stewardship, or an economics of sustainability of the sort that is only beginning to be championed–if Paraguay had the highest ration of forest loss to gain, Cambodia and Malaysia among the highest rates of loss and Indonesia the greatest increase in forest loss in the period under study, when the rate of local annual deforestation more than doubled, suggesting the complete lack of any safeguards for sustainable forestry. And rather than being based on self-reported numbers, as is often the case, the Landsat picture that emerges is effectively able to balance the objective disappearance of forested land in ways that the principal scientists broke down by year, with the aqua and red corresponding to 2013 and 2012 respectively, and orange noting years between 2000 and 2012, and yellow 2000: 
At times, such as in Indonesia and Malaysia, the effects can be particularly dramatic, if not traumatic:
The maps suggest the very limited weight carried by notions of forest growth conservation worldwide. To examine the loss of forested land alone, highlighted below by a bright magenta, the drastic diminution of forested lands lost, alone, in North America that occurred was concentrated predominantly in Canada and Alaska, including the Boreal Forest, as well as an unprecedented destruction of forested lands in much of the American South, suggests a huge shift in the human relation to the environment, and was matched with a vigorous and systematic degradation of forested lands in Russia and Scandinavia, to suggest an almost obliviousness to the losses incurred in forested lands and their habitats, as what seems a truly free market eats, rather like mildew, into the forested regions of what have been aptly called the planet’s lungs. The rather unprecedented decade-plus long expansion into forested areas is not only a displacement of natural habitats, but a severe compromising of tree cover in our lived environment, that undoubtedly contributes to the increase of global temperatures.
And to model the impact of tree losses, noted above in magenta, against the layers that mark regions of sanctioned lumber (tan) and forests that are intact (kelly green)–and even introduce layers of areas that are designated focusses of conservation. The impact of the deep incursions in Alaska’s forests is as striking as the expansion of lumbering in British Columbia, the Northwest Territories, and Saskatchewan of formerly intact forests. The isolation of forest loss alone suggests a broadly shifting Eurasian landscape, with the deepest incursions on outlying areas of Scandinavia (Sweden and Finland, to be precise) as well as the expansive forest cover across the far eastern lands of the Russian Federation–regions with forests denser and holding far greater amounts of carbon that other national forests. 
Global Forest Watch, 2001-13 MODIS information might be placed against intact forests mapped in Russia: 
And identify its relative density and biomass: 
within a record of those dispersed protected areas in Russian parks: 
The modeling of satellite data amassed at the the University of Maryland‘s Department of Geographical Sciences, with a Google Earth Engine, has led to a far more detailed interactive map to be published by the newly founded Global Forest Watch to document that shrinking lungs of the planet, when one balances the imbalances between contrasting tree cover gain (blue) and loss (pink) from 2001 to 2013 offers a way to register interaction with our environment in stunning local detail, that reveals the extent of the aggressively pockmarked surface of forests in much of northern Canada, in Alberta, Saskatchewan and Manitoba, inland of Hudson Bay. Despite a degree of forest gain, the deep incursions of tree cover loss create a grim picture of the future landscape of the continent, and suggest the benefits of layering levels of growth v. loss of forests, and revealing the clear imbalances between the two. If sustainability is about maintaining a level of balance–and of ecological equilibria–the virtual assault on the forest, that last refuge from urbanized space, increasingly seen as an obstacle to growth, reveals both an abdication of responsibility for environmental impact, and a broad scattering of the extraction of forest growth from the globe: the scattering of forest loss in remote areas, perhaps subject to less rigorous oversight, makes such a mapping of the global impact of deforestation over time particularly pertinent.
For the impact of deforestation, if we might begin from North America, is truly globalized. The concentration of tree loss in the US South is not only pronouncedly accentuated, but seems to have occurred without restraint as “wooden pellets” were gathered, often for exportation across existing wooded areas, removed as a layer of in the first map, but shown in light green below.
The northern regions reveal an even more pronounced targeting of forested areas in northern provinces jut below the Northern Territories. Despite dedicated spots for foresting in Ontario, there seems to have been a much greater expansion of regions of something approaching clear-cutting to the farther north, that tell a story of large-scale licit forest degradation in the particularly pock-marked lands of northern Alberta, Manitoba, and Saskatchewan, stained with blotches of magenta that record the intensity of forest depletion and sites of local degradation:
The same region where matches the areas of tree cover across North America.
Layering of areas of conservation reveals how several protected regions closely intersect–and indeed overlap–with the extent of forest loss, in ways that could provide a prompt for investigative journalism, as well–potentially–an illegal wood trade that is quite difficult to control: 
The local degradation of forests to the north can be placed in the context of both tan regions denoting zones that are dedicated to lumbering and the kelly green regions of intact forests, often bordering on ocean waters–
or, thanks again to Global Forest Watch, balanced against the degree of degradation of forests and range of intact forests in the data bank over an eleven year period from 2000: 
The strikingly similar selective inroads into forested areas are evident across Russia–where severe inroads in pockets of the deep forest lands north of Mongolia–seem to suggest the global character of an almost systematic program of deforestation, far exceeding the intense lost of forests in other areas of the country.
If one is to map the same region against protected forests, the composite revealed of protected areas that are often violated by loss of forests and odd balance between scattered regions of protectionism and deep inroads of forest loss are difficult to reconcile.
Or map the widespread absence of tree cover in relation to the shrinking intact forests of the region:
Or the limited growth of new forests, shown in periwinkle blue, against the lost tree cover and intact forests:
Is the concentrated incursion into forest lands–and resulting loss of forest–a shared condition condition, a result of laissez faire economics, apparent deregulation or lack of coordinated protection of forests, that is a consequence of globalism? For if globalism entails, as Giddens has it, not only ‘the intensification of worldwide social relations which link distant localities in such a way that local happenings are shaped by events occurring many miles away and vice versa’ but a shift in the understanding of place and localisms with distinct bearing on geographic understanding, the depletion of forest cover in concentrated but widely dispersed regions suggest a new understanding of forest loss. The years from 1990 has seen a dramatically unprecedented expansion of CO2 emissions, especially in developing nations, that may be closely tied to the depletion of tree-cover worldwide.
12. The loss of tree-cover quite constructively is mapped against the gain in forests, contrasting losses in bright pink/magenta against blue growth, as a means to track local variations in a spreading environmental catastrophe that suggests a colonization of former forested lands, not only due to deforestation but to the disregard for arboreal habitats, with deep losses in the boreal forest and pacific northwest that will haunt the continent to come–despite some repeatings, leading areas to be colored purple, the acute absences of forests has progressed over the interval of twelve years tracked by the LandSat images to an extent that the local environments may never recover. It may be the case, sad as it seems, that we are actually increasingly tied together and to one another in an age of globalized economies by the disappearance of forests at multiple spots across the globe: if there is a clear consequence of the 1992 trade agreement that lifted all tariffs between the US, Canada and Mexico known as NAFTA, for example, it is evident in the dispersal of trade in wood pellets and chips–at times a notorious means of smuggling–as previous duties on wood products from Canada of up to 16% on softwood and lumber were eliminated, expanding the amount of hardwood lumber imports to the US, US imports of wood more broadly, and trade of US wood to Canada (including hardwood lumber, veneer, plywood) as their prices lowered or decreased. The large amounts of oak and hardwood from Mexico to the US in pre-NAFTA days would definitely increase. While the government has encouraged such trade as an economic benefit, the expansion of forest degradation that results–and which the below map tracks–they mask the considerable global problem of greenhouse gas emissions that are due to forestry and land-use change, and the troubling finality of a change in greenhouse gas emissions hat the degradation of forests–and especially old growth or boreal forest–creates. (Clearing and burning forests creates a fifth of such emissions worldwide; the loss of trees constitutes a deeper damage on the global environment.)
And purely by mapping loss, and noting the pocking of the northern forests due to inroads of depleted tree cover:
The relation of the degradation of forests to globalization is perhaps most sharply revealed when moving to the Central America, and the regions of Guatemala and Belize mined for forest wood: 
The widespread compromising of local environments can be read through the foregrounding of layers that creates quite compelling narratives about forest-cover even for those who had limited sustained interest in the economics of wood: despite some densely intact forest landscapes inland in Malaysia, for example, and regions in Indonesia and Thailand, the tree cover loss from 2000-2013 suggests narrative of expanded logging for lumber, oil palm, and wood fibre, indicated by tan, ochre, and brown, in Malaysia, Indonesia, and Singapore and a picture of economic squandering of resources:
The degree of loss by forest fire might be isolated, moreover, to determine which sort of loss of regional carbon is described in Vietnam, Malaysia, and the Philippines:
Deforestation in central Africa seems more due to a combination of mining and logging, and seems to have grown up surrounding the remaining intact forest landscapes in the Democratic Republic of Congo, and conceals multiple narratives of commercial sacrifice of landscapes to an international demand for wood, as well as for the monies of other countries, the forests of Western Africa long depleted:
The areas of Brazil and South America that constitute the Amazon suggest a growth of compromised forests on the edges of intact forest in 2013, concealing the far greater expanse of tree cover just thirteen years earlier:
Intact forests in 2000, noting also tree cover expanse in lighter green:
Tree cover in 2000:
One is, in the end, overwhelmed by the range of maps and layovers, in ways that are almost as difficult to process as the data on which they are based. How to hold onto it, or ascertain the economical exchanges that are, so to speak, lying under these maps?
13. There has clearly been a pronounced warping since 1990 of local attitudes toward wood and forestry, and a rising appetites for wood: and despite the value of the time-lapse visualizations of forest growth or loss in a truly world-wide picture, the maps provide a point from which to raise questions about how global markets for wood are hastening the degradation of the untouched forest lands of specific environments, they also remove that data from a larger picture of economic exchange. A counerpart is offered in how the Worldmapper tool and website valuably reveals regional imabalances and discrepancies through its warped cartograms, highlighting, based on FAO statistics, the disproportional nature of the appetite for wood, and the increased reliance on international markets that concentrate the decimation of existing forests in an ever more disparate trade of woods from China, Indonesia, Scandinavia and Brazil–as well as Canada, Malaysia, and the United States. (Indeed, the specific imbalances of areas like China, which is known to buy up wood from neighboring regions and then resell wood products to the United States and Japan, offers evidence of the degree to which economies of wood are removed from woodcover questions, although wood purchases often originate form nearby areas Malaysia or, in the case of the United States, Honduras, Canada, or Belize.)
The compromising of local forests is not only due to professional farming of wood or “forestry” production of “farmed” wood, which has been nicely plotted for the year 2011 by Worldmapper in the form of a cartogram which reveals a large and flourishing industry of forest growing, using data from the FAO, in a warping of nations’ relative sizes that reflects the large-scale outsized business in forestry in China, Japan, and Indonesia, where wood seems plentiful, and across much of Scandinavia and the United States.
If the process of globalization has been pegged as convincingly as elsewhere to the consciousness of climate change around the summer of 1988–and the first collective calls to cut greenhouse gas emissions–the process of deforestation is a nice cast of the the impact of what Anthony Giddens aptly and succinctly described characterized as ‘the intensification of worldwide social relations which link distant localities in such a way that local happenings are shaped by events occurring many miles away and vice versa.’ It reveals distinct change in how we experience localness and place, and indeed a distinct change in the absence of attention to the devastating local effects of the consumption of wood–and entitlement to continued access to a perpetual availability of wood products–in an increasingly globalized economy of natural resources. Although the Worldmapper maps have the unfortunate effect of warping countries to erase place, the maps that were designed to show global imbalances in forest production, consumption, and growth provide a regional context in which to understand the losses of trees in many regions of the world, and the deforestation of particular places.
Whereas the statistics don’t include the considerable illegal wood trade, the limited nature of forest growth worldwide–nil in Canada or Russia, slim in Central America or Brazil, and significant only in some regions like the US or Vietnam where wood is an important cash crop. The production of forests in different lands seems proportionally concentrated in China, doubtless to meet local markets for wood, and is reflected in the mapping of forest growth from 1990-2005–a time over which the range of forests in much of Brazil and Mexico was rarely augmented to great extent, despite the heavy loss of forests in those regions, and a pronounced lack of the sustainability of forests in Indonesia:
The scale of planting forests surely respond to deep differences in the consumption of forests, outsized in industrialized nations, no doubt for tastes in consumption, and particularly bloated in Japan, Germany, England and the United States as well as Brazil, each of which–particularly England, Japan, and the US–seems to outstrip its production considerably; Canada clearly destines most of its produced wood for export, but China was using an outsized share of wood worldwide –given the near absence of extensive forests in its territory, after the destruction of much of the forests in the South:
The consequent degradation of existing forests worldwide might be nicely visualized, in a map generated also by the University of Maryland, this time with Greenpeace, by situating the areas of marked degradation against forests lands as of 2013, against the spectre of those forests that are now no longer intact–against which we can orient ourselves and imagine the scope and scale of the loss of woods–and no doubt the economy and ways of live that the woods provide, as much as their role as lungs of the planet that allow for its very habitation.
The issue of wood exports is clearly an issue of sensitive proportions for the hypertrophied regions of Southeast Asia, as well as North America, and one that suggests particularly pronounced effects of globalization on the wood market in both Sweden, Indonesia and Malaysia, as well as Korea, which suggests the distorted nature of the market of legal trade in wood that motivates the degradation of the forests in those countries–and to some extent in Brazil:
The effects of the loss of forest-cover seems among the most prominent–if rarely discussed–aspects of the arrival of the anthropocene, in which the subtraction of forested lands has explicitly altered the nature of the environment. Hennig was quick enough–as well as ever-industrious–to create a range of a stunning cartogram warped by the relative depletion of forests of the loss of forested environments between 1990 and 2005, which was not offset by the growth of forests in the same years. The cartogram is particularly stunning for how it depicts the disproportionate nature of the depletion of forest lands across the southern hemisphere, especially in Southeast Asia, Mexico and Brazil as well as central America and Central Africa, whose disproportional distribution amounted to a loss of 7.3 million hectares over those fifteen years alone.
Amount of Forested Land Lost in Each Country of the World, 1990-2005
At the same time, few forests grew in the southern hemisphere in that same period of fifteen years:
But the most convincing map of the global disparities that arose in the last twenty-five years is what is evident in the most distorted of cartograms showing the relative depletion of the resource of forested lands, based on the irresponsible felling of trees without provision for future growth: for the world doesn’t exactly fold in half, in this map, but the pronounced lack of responsibly sustainable growth in Guatemala and parts of Central America and much of Malaysia, India, Pakistan, and Central Africa and Ethiopia, reveals a world where poorer countries seem the largest losers, less habituated to practices of sustainability as they are, and more driven by market forces against their own interests–or at least against the interest that the cameralist Hans Carl von Carlowitz would be able to recognize.
Worldmapper/Benjamin Hennig
A compelling Worldmapper cartogram maps tree cover against local population is particularly powerful in the suggestion of how disproportionately the survival of forests is endangered by high areas of population–the very areas with an elevated populations, if not necessarily “global footprint,” are among the least forested areas of the world. And the spread of globalization often threatens precisely those increasingly isolated areas of intact forest marked in light green, revealing the relative lack of forested regions in the most popular areas–and the low concentration of intact forests in the Amazon, Central Africa, and parts of Russia.
To be sure, the scale of the radical reduction of global tree cover in a similar transformation are far withdrawn from centers of economic growth, but the remove of forests at an even greater degree from the equator constitutes a dilemma of global consequence. 
It is striking, after a somewhat exhausting world tour of the disproportionately skewed nature of forest loss and arboreal compromise, to return to the United States, that remaining densely forested areas in the continent mirrored the striking distribution of the recent map modeling the spread of highly audible levels of anthropogenic sounds across the country, based on data released by the National Park Service, and offer a telling sign of how we inhabit the land in which we live.
The relative rarity of areas of dense tree cover that remain today in the United States–together with the significant loss of wooded areas in just the past decade, and the marked degradation of forest–suggest a clear record of environmental compromise, if not an evacuation of what might be called the nation’s living landscape–even if the map indicating tree cover noted below it suggests a further diffusion of greenspace in the lower forty-eight:
The loss of tree cover in a sense stands out most prominently in the context of what degree of tree cover exists–for the spread of a loss of trees across the deep south, especially notable on the eastern seaboard and in much of Louisiana, as well as outside Denver, in Idaho, and parts of California and Oregon–suggests a loss of the local landscape that may well come back to haunt us. The spread of forest degradation is not so visibly pronounced in the US, but the extent to which the region is haunted by the specter of long-lost healthy forests or “non-intact” forests surely is–the modeling of our current forest cover is being eroded less by a rapacious economy for wood products than it is concentrated in fairly specific sites of large-scale clearing. But non-intact forests seem in clear danger of greater compromise.
14. It is striking that although the origins of the word “sustainability”–Nachhaltigkeit–and the concept of sustainability have often been traced only to recent years, expressing ideas linked to the 1969 US National Environmental Policy Act (NEPA), and for some was first coined in 1972 in Blueprint for Survival as a concept that related to man’s future. But when it was introduced in the Enlightenment, the Saxon nobleman Hans Carl von Carlowitz employed Nahhatligkeit in an illustration of his cameralist thought as a matter of good sense back in 1713.
Von Carlowitz apparently coined the ethical charge of sustainability in the context of sustained-yield forestry, Sylvicultura Oeconomica, a monument cameralist thought in forestry affirming responsible stewardship of forests. If responded to deep fears on the continuing ability to derive a sustainable economic value unless one refrained from over-forestation and depletion of lumber stocks. If written out of deep concern as a civil servant and mining inspector who sought forest ordinances in the Electoral Saxony to conserve resources for the common good, von Carlowitz deliberated the forest ordinances in theElectorate of Saxony where he served as Chief Inspector of Mining, introducing an ethics of economic conservation of nature that preceded the Tharandt Forest Academy in 1811; in calling for conservation of forests for lieben Posterität, he communicated a powerful notion of bequeathing a world undisturbed by unwisely aggressive or opportunistic interventions. Von Carlowitz’s message framed the concept of mitigating human intrusiveness on the landscape as a “sustained forest yield” around his native Saxon lands, Ulrich Grober has observed, with an intentional of the present’s responsibility to future generations, and as a reasoned reaction to the shock created by wood shortages after the Thirty Years’ War. The war created a contempoorary crisis in the availability of wood prompted assuaging of fears to ensure that the “great wood shortage . . . be pre-empted,” and awareness that “more wood was felled than grew over many ages” that were more reasoned than the deep-seated apocalyptic fears of the humanist Melanchthon’s prediction that in “the end of time, man will suffer great need for wood [am Ende der Welt man an Holtz grosse Noth leiden werde].” It is likely, Grober suggested, that von Carlowitz wrote with knowledge of John Evelyn’s hope to manage England’s forests in Sylva or a Discourse of Forest Trees and the Propagation of Timber, where he advocating the need to coordinate replanting forests to secure future ships for the navy, the “wooden bulwarks of the kingdom.” Evelyn cautioned that”Men should be perpetually planting, that so Posterity might have Trees fit for their service,” but did not do a map to chart the losses of trees that had occurred; Evelyn however articulately feared lest “we thus continue to destroy our Woods, without this providential planting in their stead, . . . felling what we do cut down with great indiscretion, and regard to the future.” These dire warnings shortly preceded how Colbert initiated a similar program for protecting forests for shipbuilding in France to calm fears about wood shortages, leading him to be cited by von Carlowitz as a model for responsible conservation. But von Carlowitz’s cameralism went farther in calling wood “essential for the conservation of mankind [daß das Holtz zur conservation des Menschen unentbehrlich sey, (p. 372)],” and constraining consumption in relation to the resources forests could support, and intentionally managing a forest’s limited resources as an incumbent responsibility and an ethics of good stewardship.

The importance of continued responsible stewardship is no longer only based on academic expertise for the common economic benefit, and transcends the concerns or training in administrative expertise. Indeed, the maps of global losses in biomass are both more shocking than the fears of an impending lack of supply for wood markets, since they reveal the steep consequences of the disappearance of tropical rainforests and subtropical biomes to meet the needs of a growing global population–both by wood extraction and the conversion of forested land to pasture.
But they provide an effective embodiment of the ongoing loss of forests that go far beyond the needs of an individual state. Even though the United Nations only used the world in a document in 1978, according to Charles Kidd, and “ecological footprint” entered public policy papers as a sort of benchmark and measurement in later years and perhaps widespread usage only after 1987 in the UN World Commission on Economic Development, the lack of a common metric of sustainability no doubt led William Rees and Mathis Wackernagel to advocate the importance of an “ecological footprint” as an ethical imperative, and its adoption as a criteria for the responsible harvesting and planting of trees (as well as, of course, in the economics of forestry).
If we have been increasingly blinded to the sense of such a footprint–even despite the continued ability to map its occurrence for decades–the rise of disproportionate deforestation of the subtropical biomes in the globalized economy finds a counterpart in the measurements of a MODIS satellite–an instrument more widely associated with surveillance and spying, to be sure–to preserve an eerily unimpeachable public record of environmental loss. Although the loss of wood is not effectively embodied in the above maps, the concept of sustainability and sustainable practices demands comparable efforts of mapping, as is partially suggested by the degree to which we risk warping the use of our resources, lacking much sense of the language of sustainability or biocapacities, absent a clear visualization of the extent of forest degradation worldwide–and an awareness of the intense over-foresting of areas of critical habitat, as well as of forests critical in their storage of carbon.
15. Those remaining areas of intact forest landscapes has receded outside many of the areas of the habited world, as the cartograms designed by the Sheffield group and Worldmapper that map forest growth against population on an equal projection reveal, suggesting how astronomical levels of population growth occur at considerable remove from forested lands in much of the world–in ways that have large consequences for the lived environments transmitted to future generations extremely significant in the maps of the future we might imagine. (It is far more difficult to visualize or imagine the loss of forests on a local level, so tremendous are they in scope. One must consider, however, the loss of forest around the areas so severely afflicted by the recent outbreak of Ebola virus, however, to start to do so.) The naming of 2013 as the Year of Intact Forest Landscapes sought to direct important attention not to the conservation of forests, but the need for the protection of the increasingly isolated islands of intact forests across the world–an image that becomes especially scary if one thinks of forests as the world’s lungs.
It is particularly worthy and jarring to remember the relatively recent date of many losses of formerly intact forest, as we consider how to use maps to start to think–or to try to start to learn how to think about–as well refamilairize ourselves with and recognize where the greatest continuous areas of tree cover in the world are located–both in the band of tropical forests along the equatorial regions of Brazil, Central Africa, and Indonesia, as well as the Russian plains and large stretches Canada above the central wheat fields and south of the Northwest Territories. These tend to be the same areas where an uneasy balance is occurring between loss and gain of forests, and the losses of of specific regions have been strikingly surpassing gains since 2000.
