Some of you may have already read this- I posted it on my facebook last spring. In a few weeks I'm giving a lecture to the environmental ethics class I TA based on this topic, so I thought I would reshare it!
One of the challenges of addressing climate change impacts is of scale. Climate change is viewed as a global issue with local impacts. Pielke Sr. et al. write that, “The IPCC and U.S. National Assessment reports start from a large global perspective and work to downscale to regional and local impacts” (2007, p. 235). For example, countries like Bangladesh are predicted to be hit hard by climate change, due to both physical (low-lying coastal country) and social (highly dependent on agriculture, pervasive poverty) vulnerabilities. Some of these vulnerable countries are the least able to prepare for climate change impacts. Thus, we tend to imagine climate change adaptation in hierarchical terms.
At a global level, decisions had until recently revolved around climate change mitigation (lessening greenhouse gas emissions), but a new paradigm of climate adaptation as a moral obligation of international development is forming. Developed countries can contribute money and expertise to developing countries that are vulnerable to climate impacts. Countries and regions will have to decide what sort of local policies might be enacted to deal with climate impacts: perhaps strengthening adaptive capacity through economic empowerment of people in poverty, or preparing for the social and political ramifications of “climate change migration” and “environmental refugees.” On a local level, however, farmers might face more immediate questions like: what environmental changes will I see this year? What crops should I plant? The top down notion of adaptation sees solutions like modeling regional impacts of climate change and developing “climate-ready” crops as desirable.
We tend to think of farmers as rejecting change-- for example, we perpetuate the ideal of the American heritage family farm. However, agriculture has radically changed over the past century in both developed and developing countries. During the Green Revolution, farmers rapidly adopted new agricultural technologies and land management practices, despite the negative social and environmental outcomes sometimes associated with these. Perhaps in less-developed countries like Bangladesh, rather than prescribing a future based on assessments of current technologies, local knowledge could be incorporated into higher level decision-making.
