Will the hashtag #droughtshaming change the public water consumption levels in California?  or is it only a manifestation of an all too long-submerged consciousness of evident property differences across most of Southern California–a space where ever-conspicuous consumption has long been made manifest in keeping yard lawns perpetually green?   and what of the Wet Prince of Bel Air, who has used an incredible 11.8 million gallons yearly during the drought to maintain the green yards on their southern California estate?

Almost as powerful a portmanteau as “Mansplaining,” the compound currently trending on Twitter presents both a righteous form of indignation, improvising map via social media that suggests our changing sense of our environment may open new arenas of public speech. The creation of a set of zoomable interactive maps from the New York Times of projected water-cuts and current water-usage across the state’s water districts have been recently mapped an uneven balance between water districts statewide, in ways that not only call clear attention to sharp discrepancies of water-usage across the state, not only between how urban and agricultural regions might be affected by mandated reductions in public water usage–

but what might be called the selective yard-drenching in specific regions of the south-lands, according to the same interactive data visualization–


drenching years in 2014-15 in LA


and the notable persistent over-use of water in wealthier areas of LA’s per diem consumption of water this past winter–


LA Consumption habits per diem Winter 2015


The map above offers an approximate reflection of a topography of disposable income, described b UCLA’s California Center for Sustainable Communities.  The Center quite recently found not only that “wealthy used more than three times the rate of non-wealthy people,” but wealth was the most conspicuous correlation and predictor of water use–and watering lawns, as we have long known, an increasing sign of conspicuous consumption even in an age of drought.

Is this a decision to spend more on water, or is it, as seems more likely, the conspicuous expenditure of water on yards, perhaps fueled by the cost of letting all that greenspace go dry, or the actual dangers of fire hazards that letting lawns go dry might create?  The oft-cited datum that Beverly Hills residents daily “used” some 286 gallons of water during September 2014, at the same time northern and coastal San Diego County consumed some 584 gallons in the Santa Fe Irrigation District, contrast sharply to Compton residents served by the LA Department of Water and Power who restricted themselves to 93 gallons a day and Angelinos in East LA some 48 gallons.

But it bears repeating at a time when Governor Brown wants to mandate across the board 20% reductions in water use as a means of increasing efficiency, if only to ask what some of the best manners of mandating reductions are.  By dividing water-usage by census tract, clear patterns in LA County emerge, that make it something of an epicenter, to mix geographic metaphors, with the recent rash of tweets about excessively selfish individual water use at Beverly Hills mansions that include, in some cases, spas and vineyards as well as expansive still-green lawns:


Water:Income LA


But rather than only call attention to the sociological correlation between water-waste and wealth, this post wants to ask questions about the ethics of the spontaneous sorts of mapping of water-waste that have proliferated in Angelino social media, as if to sharpen critiques of the lack of social responsibility of the wealthy in a city of sharp social divides, in ways that remote sensing is promising new results in a far more detailed manner for select Los Angeles neighborhoods in order to drill more deeply into the extent of watering of lawns, flowers, and trees that underlies such datasets.  But human-scale photographs posted on social media via Twitter has been an initial means to assemble immediately available instances of water over-use.

The spontaneous mapping of such inequalities on social-media is a sort of crowd-sourced shaming to redress unspoken social inequities, with offending addresses lain out on twitterfeeds for the public to see, lest anyone be confused about who has the public interest at heart, and who is most concerned with keeping the brown grass at bay, even without looking at the bigger picture, in something approximating collective rage against the overwatered large yard as an exercise of collective shaming, which has gained a real edge given that the state is poised to levy hefty fines on identified water wasters since mid-2014.  It’s triggered a geographical awareness of the steep inequities of water use and comes close to socially sanctioned class-consciousness–




–and its effects on the lived landscape ofBeverly Hills lawns:




Such selective outing of levels of outrageously cartoonish disproportionate use of water utilities may run the ethical risk of crowd-sourced surveillance, where aerial photography approaches NSA-style snooping via overhead drones–the regional sustainability manager for Sacramento’s Utilities Department was said to be “pleasantly surprised” at such snitching last summer, when #drougthshaming took off on the Twittersphere.  But the current spate of tweeted outrage expressed on social media has also become a venue for expressing suppressed sentiments of a class struggle, very slightly veiling disgust at profligate over-watering lawns indulged by those running automatic sprinklers as if they were draining regional aquifers single-handedly, with little heed for state-wide water shortages, brought to the front in signs posted in public parks that remind users that “Brown is the New Green.”

Tweets are most famous for unleashing wrath against the privileged who are out of touch with the reality of water-needs–


green lawns



–at the fact that rhythms of daily consumption patterns are so drastically different across a single city by degrees of multipliers.  And is it even a surprise that the mansions of three and a half acres we’ve become used to viewing and vicariously living on Reality TV have been most notoriously cautioned by local Municipal Water Districts to cut the their water use drastically?  (Both Barbara Streisand and Kim Kardashian have publicly agreed to curtail their water use–“Kim takes this drought seriously;” said a representative; “she has no problem letting her grass go brown.”)

The targeted social criticism is by no means limited to the super-wealthy:

Sprinklers Running since <7AM

The steep social discrepancies in water-use have thrown into relief the divided economic structures of the city that we’ve long known about from the American Community Survey–Orange County and Palos Verde residents use respectively thee and two times the state-wide per capita daily consumption rates in February 2015–but now suggest that water wastage among the wealthy is actually undermining the public good in a clearly mappable manner.  We have long seen larger yards in specific neighborhoods, but watering practices seem to have grown out-of-hand in expropriating the public resource with obliviousness, even while we blame “nature” for a drought that is increasingly evident is indeed largely man-made, and even may as due to human nature as climate change.

LA in detail


During the summer, such deep discrepancies of daily water consumption are of course placed into even further relief in  data visualizations of local levels of consumption, reflecting an apparent rationalization of increased water usage as well as the readiness of covering rising water costs, as lower income families responded more rationally to higher water costs.

To be sure, Northern California has done fairly well to reduce consumption from the Spring 2013–

But it is also true that the aerial photographs of the ambient effects of income inequality that sent Google Earth images viral after being posted on persquaremile reveal the grey v. green dichotomy to be by no means limited to the southland–




Such a democratic appropriation of Google Earth may have paved the way for the tweeting of extravagant consumption of water that has become all too evident in some of the larger Beverly Hill yards, that can be linked to specific addresses.

The calls for greater restraint in water usage since March 2013 is far from clear in much of the greater Los Angeles area, as posters on social media have not only realized, but realized that they were able to publicly point out.


SoCal 2013-15

Both a more equitable distribution of water access and a rethinking of such deeply-lying assumptions of personal prerogative to wasting water deserve attention as Californians try to curb continued water use in a responsible manner.  We will have to tilt swords with some of the deeper espousers of a free market of deregulated water consumption, but at this point, for better or worse, deregulation has its back snugly against the wall.

And despite the reluctance of water utilities to identify wasters of boggling amounts of public water–as the Los Angeles homeowner known only as Wet Prince of Bel Air, a name won for pumping an incredible annual 11.8 million gallons during the recent drought to his estate.  The recent news that 100 residents of such wealthy Los Angeles neighborhoods as Westside have been pumping millions of gallons of water apiece has called for more effective means of recourse than twitter revenge, as such outing bears little fruit; in the light of recently passed laws against over-use of water, remote sensing technologies have been used by journalists at Reveal who are eager to even up the score:  taking advantage of   new fines assessed against excessive water use, the mapping through Digital Globe and others provides a deeper survey of water use than would be released by Los Angeles’ compliant Department of Water & Power.  Indeed, the Center for Investigate Reporting has begun to “out” high water-users by remote sensing–and publishing the maps!

Given the limits of Twitter photographs to document public instances of water overuse, the expansive indulgence of overwatering in such somewhat reclusive sites as Bel Air, perhaps inspired by droughtshaming, have used remote sensing provides a means to assess an accurate record of water-use to map the high use of water to estates to out individual culprits of over-watering, tracking the greening of their gardens by Google Earth and Digital Globe and an assessment of exactly how healthy those yards are.


Using remote sensing of the health of plants–by means of a form of remote sensing developed to detect plant health common in agricultural assessment– the Normalized Vegetation Index (NDVI) helps to pinpoint individual culprits of water over-use might be identified whose identity would be otherwise kept hidden by the county, by measuring the living vegetation that has continued its ability to absorb visible light wavelengths of light, the very ones used in photosynthesis, to create a unique dataset of those with the largest living yards in the municipality.

For the primary culprits are be identified by remote sensing of living green vegetation that remain on such sites as the heavily wooded estate that is maintained by move producer Peter Guber, part-owner of the Golden State Warriors, who indulges his wooded estate with over 2.8 million gallons of water each year, while pushing the Warriors to take up a home in San Francisco to boost their revenues.  The owner of the 42-room French-style chateau from TV’s “The Beverly Hillbillies,” former Univision CEO Jerrold Perenchio, who uses up to 6.1 million gallons each year to water his plants and gardens.  The owner of the 28,000-square-foot “Bellagio House” whose floral gardens suck up over 4.6 million gallons per year.  The technology used of combining infrared and near-infrared light by the Normalized Vegetation Index (NDVI).    The NDVI has become sufficiently refined from satellite or drone remote observation to parse and better describe water use and its impact in plants with a great precision, as is evident in the MODIS satellite maps of groundwater in the United States, and to present a highly sensitive reading of vegetation health at precise moments in time, and indeed within given parameters of health, by mapping the presence of water in plants–as one would map the presence of water in the ground.


By means of a similar remote sensing with NDVI, one can effectively map lots’ local water saturation at a scale to detect individually owned gardens such as those that Guber indulges on Lausanne Road in Bel Air–outlined below , with relative vegetative health shown in red colors, showing the highest range of the NDVI–as an accurate way to assess the extent of living vegetation, using infrared and near-infrared light to measure the local health of vegetation with amazing sensitivity, much as is familiar from global maps–but is only recently possible at such low scale thanks to Digital Globe–in ways that can not only identify individual culprits of water over-use, but presumably take them to task.

For unlike the yellowed out areas of most of even the region of Bel Air, the bright red expanses suggest an odd over-nourishment of gardens even in a time of drought that indeed seems quite newsworthy, and is perhaps able to be viewed by Digital Globe alone.

While such remote sensing from satellites had been confined to national regions at specific times of year,



–or used to map global differences in plant health–


–the local assessment of those who over-indulge in caring for their lawns and flowers is both something close to surveillance and perhaps a form of surveillance that recent laws about water use have sanctioned in California during our current drought.

The odd triangles and spots of green that remain in a drying out landscape in which most of the rest of us live (spot the non-arboreal light green track in the tan landscape shown below?) reveal the levels of water waste which demand to be curtailed, and are emblematic of the golf courses and overwatered farms that we’ve just begun to take stock.

Arctic Circles

On our annual northward migration to Ottawa this December, we gathered around the unused fireplace in an unheated living room during the warmest Canadian Christmas in personal experience–as well as in the public record for Atlantic Canada, where local records for rainfall have surpassed all earlier recorded years.  Perhaps because of this, discussion turned to ownership of the North Pole for the first time for some time, as what was formerly a featureless area of arctic ice has become, as a receding polar ice-sheet exposes possible sites of petroleum mining, to become an area of renewed land grabs and claims of territoriality, as their value for nations is primarily understood in a global market of energy prospecting.  The story of the new mapping of territorial claims around the arctic ice cap goes back decades, to the exploration of offshore polar drilling, but the exposure of land raises new questions for mapping because boundaries of polar sovereignty are contested, even as oil companies have speculated by modeling sites of future exploration for petroleum deposits.

Although one assumption circulated that the place was Canadian by birthright—birthright to the Arctic?–since it is so central to national mythistory.  But there’s as much validity for its claims as the more strident claim the explorer Artur Chilingarov made to justify his planting of a Russian tricolor in the murky ocean bed 2.5 miles below the North Pole, during the 2007 polar expedition of the Mir submarine, with the blunt declaration that “The Arctic has always been Russian.”  Canadian PM Steven Harper did not hesitate a bit before decrying these claims to territoriality, warning his nation of the danger of Russian plans for incursions into the arctic in his tour of Canada’s North, thumping his chest and professing ongoing vigilance against Russia’s “imperial” arctic “imperial” as a national affront in addressing troops participating in military maneuvers off Baffin island as recently as in 2014.

Harper’s speech might have recalled the first proposal to carve pie-shaped regions in a sectorization of the North Pole first made by the early twentieth-century Canadian senator, the honorable Pascal Poirier, when he full-throatedly proposed to stake Canada’s sovereign claims to land “right up to the pole” and transform what had been a terra nullius into an image of objective territory seemed once again at stake.  Poirier claimed jurisdictional contiguity in declaring “possession of all lands and islands situated in the north of the Dominion.”  Poirier’s project of sectorizing the frozen arctic sea and its islands, first launched shortly after Peary’s polar expedition, has regained its relevance in an age of global warming, arctic melting and climate change.  But the reaction to the expanding Arctic Ocean in a language of access to a market of commodities has inflected and infected his discussion of the rights of territoriality, in ways that have obscured the deeper collective problems and dilemmas that the eventuality of global warming–and arctic melting–broadly pose.


Arctic Teritorial ClaimsEncyclopedia Brittanica


The question of exactly where the arctic lies, and how it can be bounded within a territory, or, one supposes, how such an economically beneficial “good” that was part of how parts of the north pole might get away from Canada, has its roots in global warming–rather than in conquest.  The dramatically rapid shrinkage of ice in the Arctic Sea has raised newly pressing issues of sovereignty; the widespread melting of arctic ice has made questions of the exploitation of its natural resources and potential routes of trade has made questions of the ownership of the Arctic ocean–the mapping of the territorial rights to the seas–increasingly pressing, as some 14 million square kilometers of Arctic Ocean have emerged not only as open for exploration, but as covering what has been estimated as 13% or more of total reserves of oil remaining to be discovered world wide.


20141220_IRM937 The Economist

While it seemed unrelated to the ice melting from nearby roofs, or large puddles on the streets of Ottawa, conflicting and contested territorial claims that have recolored most maps of the Arctic so that its sectors recall the geopolitical boardgame RISK, that wonderful material artifact of the late Cold War.  Rather than map the icy topography of the region as a suitably frosty blue, as Rand McNally would long have it, we now see contested sectors of the polar regions whose borderlands lie along the Lomonosov Ridge (which runs across the true pole itself).  The division of the pole so that it looks like post-war Berlin is an inevitable outcome of the fact that the arctic is warming at twice the rate of the rest of the planet, resulting in the opening of an area that was for so long rarely mapped, and almost always colored white with shades of picturesque light blue to suggest its iciness.

The lands newly revealed in the northern climes have however led territorial claims of sovereignty to be staked by a four-color scheme of mapping.  The uncovering of arctic lands–in addition to new technologies for underwater oil extraction and sensing–have complicated the existing maps of ocean waters premised upon expanding existing territorial waters an additional 278 kilometers beyond what can be proven to be an extension of a landmasses’ continental shelf–expanding since 1984 the rights to Arctic waters of the United States, Denmark, and Canada, according to consent to the United Nation’s Law of the Sea Convention (UNICLOS) which sought to stabilize on scientific grounds competing claims to arctic sovereignty.



Arctic Boudnary Disputes


The issues have grown in complex ways as the melting of Arctic ice has so dramatically expanded in recent years, exposing new lands to territorial claims that can be newly staked on a map that unfortunately seems more and more to resemble the surface of a board games.  Even more than revealing areas that were historically not clearly mapped for centuries, the melting of the polar cap’s ice in the early twenty-first century has precipitated access to the untapped oil and gas reserves—one eight of global supplies—and the attendant promise of economic gains.  Due to the extreme rapidity with which polar temperatures have recently risen in particular, the promises of economic extraction have given new urgency to mapping the poles and the ownership of what holes will be drilled there for oil exploration:  instead of being open to definition by the allegedly benevolent forces of the free market, the carving up of the arctic territories and disputes over who “owns” the North Pole are the nature follow-through of a calculus of national interests.  The recent opening up of new possibilities of cross-arctic trade that didn’t involve harnessed Alaskan Huskies drawing dog sleds.  But the decline in the ice-cover of the arctic, as it was measured several years ago, already by 2011 had opened trade routes like the Northwest Passage that were long figures of explorers’ spatial imaginaries, but are all of a sudden being redrawn on maps that raise prospects of new commercial routes.   New regions assume names long considered but the figments of the overly active imaginations of early modern European arctic explorers and navigators in search of the discovery of sea routes to reach the Far East.

On the one hand, these maps are the end-product of the merchant-marine wish-fulfillment of the eighteenth-century wishful mapping of the French Admiral Bartholomew de Fonte, whose maps promised that he had personally discovered several possible courses of overcoming a trade-deficit caused by British domination of the Atlantic waters, allowing easy access to the South Seas.  The imagination of such routes proliferated in a set of hopeful geographies of trade which weren’t there in the late eighteenth century, of which de Fonte’s General Map of the Discoveries is an elegant mixture of fact and fiction, and imagined polar nautical expeditions of a fairly creative sort, presenting illusory open pathways as new discoveries to an audience easily persuaded by mapping pathways ocean travel, even if impassable, and eager to expand opportunities for trade by staking early areas of nautical sovereignty to promise the potential navigational itineraries from Hudson Bay or across the Tartarian nation of the polar pygmies:



Open-ended geographies of land-masses were given greater credibility by the dotted lines of nautical itineraries from a West Sea above California to Kamchatka, a peninsula now best-known to practiced players of the board-game RISK:



As well as imagine the increase potential shipping routes that can speed existing pathways of globalization, in fact, the meteorological phenomenon of global warming has also brought a global swarming to annex parts of the pole in confrontational strategies reminiscent of the Cold War that tear a page out of the maps, which give a similar prominence to Kamchatka, of the board game ‘RISK!’  Will their growth lead to the naming of regions that we might be tempted to codify in a similarly creatively improvised manner–even though the polar cap was not itself ever included in the imaginative maps made for successive iterations of the popular game of global domination made for generations of American boys.

Will future editions expand to include the poles as well, before they melt in entirety, as the ways that they become contested among countries percolate in the popular imagination?

We must await to see what future shorelines codified in the special ‘Global Warming Edition’ of RISK–in addition to those many already in existence in the gaming marketplace. If the game boards suggest Christmas activities of time past, the ongoing present-day game of polar domination seems to be leading to an interesting combination of piece-moving and remapping with less coordinated actions on the parts of its players.  We saw it first with Russia’s sending the Mir up to the North, which precipitated how Norway claimed territoriality of a sizable chunk of Arctic waters around the island of Svalbard; then Denmark on December 15 restocked its own claims, no doubt with a bit of jealousy for Norwegian and Swedish oil drilling, to controlling some 900,000 square kilometers of arctic ocean north of Greenland, arguing that they in fact belong to its sovereign territories, and that geology reveals the roots of the so-called Lomonosov Ridge itself as an appendage of Greenland–itself a semi-autonomous region of Denmark, upping up the ante its claims to the pole.

While the Russians were happy to know that their flag was strategically but not so prominently placed deep, deep underwater in the seabed below the poles, the problem of defining the territorial waters of the fast-melting poles upped the ante for increasing cartographical creativity.   Recognized limits of 200 nautical miles defines the territorial waters where economic claims can be made, but the melting of much of the Arctic Ocean lays outside the claims of Canada (although it, too, hopes to stake sovereignty to a considerable part of the polar continental shelf), by extending sovereign claims northward from current jurisdictional limits to divide the mineral wealth.  Were the Lomosonov Ridge–which isn’t moving, and lies above Greenland–to become a new frontier of the Russian state, Russian territory would come to include the pole itself.

The actual lines of territorial division aside, the diversity of names of the single region indicate the competing claims of sovereignty that exist, as if a historical palimpsest, within an actual map of the polar region:  from the Amundsen Basin lies beside the Makarov Basin, the Yermak Plateau beside the Lena Trough and Barents Plain, suggesting the multiple claims of naming and possession as one approached the North Pole, without even mentioning Franz Josef Land.




amundsen basin dotted lines of contestation?.png

Contestation of the Pole

While the free market isn’t able to create an exactly equanimous or impartial division of land-claims, the new levels of Denmark’s irrational exuberance over mineral wealth led the country to advance new claims for owning the north pole, and oil-rich Norway eager to assert its rights to at least a sixth of the polar cap, given its continued hold on the definition of the northern lands.  The increasing claims on proprietary rights of polar ownership among nations has lead international bodies such as the United Nations Conventions on the Law of the Seas (UNICLOS) to hope to codify the area peaceably by shared legal accords–presumably before the ice-cover all melts.

The maps of speculation of the “Arctic Land Grab” is economically driven and suggests an extension of offshore speculation for oil and gas that has long roots, but which never imagined that these claims would be able to be so readily concretized in terms of a territorial map as the melting of the ice cap now suggests.  But as technical maps of prospecting are converted into maps with explicit territorial claims, planned or lain lines of pipe are erased, and the regions newly incorporated as sites of territoriality in ways that earlier cartographers would never have ventured.

Bill Rankin/Guerilla Cartography

The existence of laid or planned pipeline by which to pump and stream oil across much of Upper Canada from the Chukchi Sea, North Slope, and MacKenzie Delta have long been planned by Canadians.  Similarly, the Russian government, echoing earlier claims of Russian stars to straddle the European and Asian continents, have claimed the underwater Lomosonov Ridge as part of the country’s continental shelf, even if it lies outside the offshore Exclusive Economic Zone, as is permitted by UNICLOS–so long as the edge of the shelf is defined.

Canada has taken the liberty to remap its own territory this April, in ways that seem to up the ante in claims to arctic sovereignty.  In updating the existing map of 2006 to make it appear more ice exists in the Arctic than it had in the past,  the Atlas of Canada Reference Map seems to augment its own sovereign claims to a region in ways clothed in objectivity:  even as arctic ice-cover undeniably rapidly melts in a decades-long trend, the ice-cover in the region is greatly expanded in this map, in comparison to that of 2006, and the northern parts of Canada are given a polemic prominence in subtle ways by the use of a Lambert conformal conic projection and a greatly expanded use of aboriginal toponymy to identify lands that even belong to different sovereignty–as Greenland, here Kalaalit Nunaat–in terms that link them to indigenous Canadians, and by extension to the nation.  Both tools of mapping appear to naturalize Canadian claims to the Arctic in a not so subtle fashion.  Moreover, the map stakes out exclusive economic zones around Arctic regions:  even as the Arctic rapidly melts, for example, disputed islands near Greenland, like Hans Island, are shown clearly as lying in Canadian waters.

Canada with Polar Claims, Parks

Perhaps what exists on paper trumps reality, creating an authoritative image of an expanded Arctic–a white plume that expands the amount of Arctic ice beyond the rendering of the Arctic Sea in its earlier if now outdated predecessor.

What exists on paper, once officially sanctioned, seems to trump the rapidly shrinking extent of arctic ice.  The map trumps reality by blinding the viewer, ostrich-like fashion, or keeping their head deeply buried in the proverbial sand.  The decision to show the thirty-year median of sea-ice extent in September in the years between 1981 to 2010 brings the map into line with the way that Environment Canada computes sea-ice extent.  And the augmentation of Inuit toponymy for regions near the Arctic recognizes the indigenous role in shaping Canada’s toponym.  But it would be hard to say that either would be advanced if they did not have the effect of expanding Canadian sovereignty to the arctic.  The reality it maps clearly mirrors the shifting interests of the state at a time of the shrinking of Arctic ice due to climate change, more closely than it shows the effects of global warming on the ice-cover of the northern regions, let alone in the Arctic itself.  With more maps that diminish the effects of global warming, the orienting functions of the map seem to be called into question in themselves.

Merry Christmas indeed!

Smelling the Coffee

Coffee beans lying on a burlap sack map the entire world, but belie the fact that the area suitable for growing coffee beans stands to be reduced by as much as half by 2050, if climate change continues, and the Arabica beans grown in tropical highlands stop receiving the year-round rains that not only enable but nourish their growth.  If that isn’t a wake-up call, what is?  Some 25 million farmers rely on their production of the beans–most of whom are small farmers–but rising temperatures predicted could radically reduce and effectively circumscribe what those in the know call the “coffee map.”

The sorts of disruption in growing beans that localized drought in those tropical highlands seems almost destined to bring–as the worst dry spell in decades that hit Brazil’s coffee belt, destroying a third of the crop or a decline by a half in coffee bean yields in Tanzania since the 1960s, as temperatures warm and the ground becomes more wet, stand to grow not only the price of the two and a quarter billion cups of coffee we humans consume daily, in what seems like a private experience, meaning that the beans will no longer be so abundant in those burlap bags.  In Columbia alone, coffee leaf rust that is the consequence of weather that is both warmer and wetter stand to damage some 60% of the country’s agricultural land by 2050, making for a decreased abundance of beans and ever more removed cup of joe.  Indeed, coffee beans are particular enough about growing conditions that to remain optimal conditions of production, the temperature should remain between 18–21°C, and once rising above 23°C, bean quality declines and the plant grows far too fast, noticeably changing its taste, flavor bouquet, and aroma . . . with a detectable shift occurs with only a rise of only half of a degree at the wrong time in the growing season, in ways that could change coffee harvests far sooner that one might expect.

Coffee beans map


More than any other sector of life, the tremendous growth of coffee consumption over the past decades invites a daily morning exercise of geographic literacy. In hubs of metropolitan coffee drinking, the local origins of beans are invested with a provenance that is supplemented by detailed descriptions of their practices of cultivation.  The geographic here primarily signifies or maps to the gastronomic; provenance of coffee has a deeper resonance than the locations of their roasting, and erases the huge distances traversed in their transportation or the local climates in which they were produced. The importation of coffees and costs of coffee farming are naturalized within local coffee bars as a geographic palate, as we’re accustomed to having Sulawesi, Rwanda, Burundi, and Tanzania among the rotating coffees of the week, and in our cups; their names, instead of the once-dominantColumbian or Brazil beans, are part of our routines that are often stripped of geographic signification as place-names–even though they might be better understood as a geographic lesson with climate warming as its subject.  Can maps help?

The lopsided distribution of this conversion of toponymy into gastronomy is evident in a map of where this huge rise of coffee consumption and importation has occurred.  If coffee beans were introduced to the future United States in the eighteenth century, coffee has become among the leading importers of beans worldwide.  Americans now consume some 23 gallons each day (or 22.1 according to Wikipedia)–but declined far below the 48 gallons Americans were said to consume annually in 1946–0r the 62 gallons downed annually in far chillier Finland.  Yet it has become part of bloodstream–literally–and an unprecedented (although we lacked earlier metrics) 161,000 folks listed coffee making or serving as a “skill” in 2013.

We might call this the browning of North America, ignoring that the distribution of local blends, pioneered by Peets and popularized by Starbucks, before being refined by Blue Bottle or Four Barrel, masks variations in a topography of coffee drinking in the United States far more variegated than the homogeneous brown of the United States.  (The fact that Canada is yellow may seem comforting, but conceals the very urban nature of this social ritual:  notice how those brown dots congregate around Toronto, Montreal, Vancouver and Ottawa . . . )   The absurdity of nationally ranking habits of daily caffeination aside (although there’s an academic press title in here somewhere), the most striking aspect of this map is the huge area of the world left in white, shown here only from the equator since no countries below the equator import coffee beans in such quantity.


Coffee IMporting Countries- Top Ten



Indeed, the ten largest coffee importers, mapped in yellow, not brown, suggests an imbalance of equatorial countries whose products tend to wake up folks in northern climes.

The more detailed mapping of the production of coffee by bags of beans, mapped by Oxfam for 2001, showed a nicely skewed data distribution, with those non-growing regions left suitably blank, as if they thirsted for the brown stimulant that came pouring (or steaming) in from equatorial climes:

There is a clear “coffee belt” whose discovery and demarcation the Coffee Grower Association of Hamburg claims responsibility for:


coffee_beltGerman Coffee Association


And a lot of imported coffee is needed–creating what has indeed long been a pretty big business interest in the US, even before the boutiques of metropolitan areas from the 1990s.  Even if, once this huge amount of unroasted beans is divided per capita, rendering regions like Canada and Scandinavia distinctly darker, and measured by consumption of cups/day alone, the geographic distribution looks a bit different in 2011 when mapping coffee consumption per capita in this clickable map of circa 2008:


2011 coffee map





Which returns us to the interests that all maps conceal.  By the alchemy of toponymy, the regions from which the beans themselves derive, of course, come from the very equatorial regions that are the sites of forestry.

This is evident in this far more anodyne map, prepared by someone trained in the school of neo-corporate graphic design:

I appreciate the hand-drawn oval projection, crafted with care in the midwest city of big shoulders, which suggests that if all roads led to Rome, all beans flow to Chicago:


Global sources of coffee on ms map


A more informed map might link the cultivation not only to forested regions, but to the very “hot spots” whose local biodiversity is most threatened by global warming, and where the inefficient use of water widespread in coffee cultivation least practical and most pernicious.  For it is not only equatorial areas, but from the driest areas on earth:

The overlap of ‘hot spots’ map onto coffee-growing regions alarms; coffee cultivation is widespread in 16 of the 34 most threatened ecosystems.  And this is the tip of the iceberg, to use a somewhat mixed metaphor unless one considers iced coffee, of the paradox: privileging the locality of cultivation in maps of caffeine consumption reinforces the fragility of local ecosystems.  This is a very different map, speaking map now, from the manner that an  earlier cartographical image set the details of consumption as an inevitable but conscious choice, concentrated in one icon, as opposed to the naturalization of growing in isolated pockets of uniform unattractive gray:

Indeed, the conscious coffee drinkers at the Water Footprint in the Netherlands have mapped the severely disproportionate gross virtual water import that results worldwide:


Coffee's Water
The “flows” of coffee beans might be mapped, if somewhat less legibly, in comparison to those of chocolate, whose parallel commerce from the New World matches it as a popular stimulant from the New World, as Mary Norton reminds us, that in fact was similar in its function to coffee:


Coffee and Chocolate


In part, this is a local story, with much of the jumping value of java able to be registered in the Port of Oakland, as shown in this bar graph which groups all beans as a whole, independent of locality, but reflects Oakland’s significance as a global hub of the importation of coffee beans.




Let’s recall the lopsided nature of a current map of coffee indulgence that this demand reflects:

and consider the possibility of a re-mapping our daily habits or affectation for caffeination, through this map of the network of coffee distribution and consumption, removed from most familiar geographic categories.  The schematic map is courtesy San Jose-trained Roxanne Pasibe:




In the initial graphic, the beans naturally drop to the ground, and into our bags. Let’s try to map how they come to get there, and into our cups.
