My colleagues are I recently published a paper in BioScience, Untangling the Environmentalist’s Paradox: Why Is Human Well-being Increasing As Ecosystem Services Degrade?

The paper originated from the involvement of the first four authors, my former PhD student Ciara Raudsepp-Hearne, my colleague at McGill Elena Bennett, and my former post-doc Maria Tengö and I, in the Millennium Ecosystem Assessment.  While we were all happy with our work on the MA, we felt that the MA had not had enough time to digest its findings.  I was particularly interested in the apparent contradiction between the MA’s assumption that ecosystem services are essential to human wellbeing and the observation that human wellbeing has been increasing as ecosystem services decline.

Our paper compares four alternative explanations of this apparent contradiction.  Our abstract outlines the paper:

Environmentalists have argued that ecological degradation will lead to declines in the well-being of people dependent on ecosystem services. The Millennium Ecosystem Assessment paradoxically found that human well-being has increased despite large global declines in most ecosystem services. We assess four explanations of these divergent trends: (1) We have measured well-being incorrectly; (2) well-being is dependent on food services, which are increasing, and not on other services that are declining; (3) technology has decoupled well-being from nature; (4) time lags may lead to future declines in well-being. Our findings discount the first hypothesis, but elements of the remaining three appear plausible. Although ecologists have convincingly documented ecological decline, science does not adequately understand the implications of this decline for human well-being. Untangling how human well-being has increased as ecosystem conditions decline is critical to guiding future management of ecosystem services; we propose four research areas to help achieve this goal.

BioScience has highlighted the article by writing a press release, providing a set of teaching resources, and featuring the article in the issue’s editorial.  BioScience’s editor-in-chief Timothy M. Beardsley writes:

… BioScience will publish commentary on aspects of their analysis in a future issue. Yet the article clearly strengthens the case for research that integrates human well-being, agriculture, technology, and time lags affecting ecosystem services. Raudsepp-Hearne and her colleagues urge more attention to how ecosystem services affect multiple aspects of well-being, ecosystem service synergies and trade-offs, technology for enhancing ecosystem services, and better forecasting of the provision of and demand for ecosystem services.

The recent oil calamity in the Gulf of Mexico, the biological impacts of which will take years to fully manifest and will persist for decades, should be reminder enough that although technology can insulate us from degrading ecosystem services locally, it often does so by creating problems elsewhere. As the human population grows, fewer places remain where the impacts can be absorbed without adversely affecting somebody. Aggregate global human well-being is, apparently, growing—though it is obviously declining in some places. Extending and defending the gains, particularly as the quest for energy becomes more intense, will require policymakers to understand the complicated relationship between ecosystem services and the humans who use them.

I’ll summarize our paper and respond to some of the media coverage of our paper in followup posts.
