This little AFP article on this week’s TEEB report for policymakers was more than enough to pique my interest. TEEB is The Economics of Ecosystems and Biodiversity, a group hosted by the U.N. Environment Programme, and supported by the EC, Germany, the U.K., and others. The group’s insights are many and quite rare, but the general strategy is to argue that because the benefits of environmental conservation are often widely diffused and difficult to codify, the market does not properly account for them. The TEEB program aims to rectify this deficiency by helping to assess the costs of environmental degradation and propose market-based steps that can properly weigh these costs against those costs that would be incurred by preventive measures.
An unusually broad effort to assess the benefits of environmental assets yields unusually progressive recommendations. Coming to appreciate the huge, varied, and irreplaceable benefits of biodiversity, for example, recommends halting deforestation, protecting coral reefs, and fisheries management. In each case, the benefits of existing environmental assets outweigh the gains from exploitation; likewise, the cost of conservation is far lower than the cost of repair. Even the latter can be substantial, however: raising the percentage of oceans covered by marine protected areas from 0.5% to 20-30% “could create a million jobs, and sustain a marine fish catch worth $70-80 billion/year,” effectively doubling the output of the global fishing industry. Converting mangroves to shrimp farms in Southern Thailand could return $1,220 per hectare per year on an unsustainable basis; the benefits of maintaining those same mangroves, from firewood, as nurseries for offshore fisherman, and coastal protection against storms totals $12,392/ha/yr—an order of magnitude larger. In a particularly narrow cost/benefit calculation, pollinators from nearby forests can increase crop yields at coffee farms some 20% over less proximate farms. In each case, an investment in conservation now doesn’t just save money later (which it does—a lot); it produces benefits now, from water purification, erosion control, carbon sequestration, protection against catastrophic events, tourism, a basis for scientific research, and so on and so forth.
Take two of the most astounding figures. The estimated costs of halving deforestation globally are somewhere between $17.2 and $33 billion/year; failing to do so means incurring costs from climate change of $3.7 trillion! (Which is why we need REDD.) It can be difficult to wrap your head around a large number, so notice that that’s 100-200 times as much, or about a quarter of U.S. GDP. Here’s another huge number: economic subsidies globally (to agriculture, fisheries, mining, and energy, “represent about 1% of global GDP yet many of these contribute directly to biodiversity and ecosystem damage. Coincidentally, the Stern Review of the Economics of Climate Change found that 1% of global GDP should suffice to prevent future climate change damage expected to cost 5% to 20% of global GDP.” (32)
To be clear, the TEEB approach is not a perfect solution. Even with an adequate assessment of the costs of environmental decline, markets may still prove too acceptant of the risks and costs of environmental exploitation. As in other fields—most notably, public health, and development—markets are likely to be unable to meet robust standards for human welfare. Put simply, we owe more to the environment and to ourselves than economic markets will allow for. But that is not to say that TEEB isn’t an excellent first step: the first battles in the fight back to sustainability must be fought over interest, in the hopes that more substantial norms can be inculcated in the process. Besides, sustainability is the necessary step; what we owe to the environment beyond stability is a debatable matter for ethicists, politicians, and humans. We owe sustainability first and foremost to ourselves.
This is the strongest point (among many) in the TEEB report. This, and the numbers given above, are astonishing given that we expect governments to be fairly rational in terms of cost-benefit calculation. Instead, governments seem not to be capable of weighing the costs of environmental degradation across time, even when they really are the simplest of calculations: $1 million replanting mangroves in Vietnam now, or $7 million in dyke repairs later (plus god only knows what else). And of course governments are all we can look to in such cases: diffuse benefits, and future costs, are rarely lobbied for; especially given that it is the poor who derive the greatest benefits from biodiversity and pristine habitats, it is governments that must speak for the long-term prosperity of nations as a whole. At present, no form of government seems to be capable of adequate rational calculation over the medium term, nor of grasping intricate and diffuse benefits spread throughout society.
I’ve argued before that something will have to be done about accommodating democracies to their existence in time. Perhaps something can be learned from the fact that the EU is on track to meet and exceed its Kyoto obligations? Though there is no reason this should be so in the case of TEEB’s positive sum dynamics, in general it stands to reason that large forms of political organization should be more sensitive to more diffuse benefits. With all the emphasis that international theory places on the importance of defending sovereignty, perhaps state governments can understand this calculation: demonstrate a capability to address the environment, or someone else will.
