Reuters recently
reported that India and China have been in covert conversations over the last two days regarding next month's
climate change talks in Copenhagen. The two countries have apparently reached consensus on some major issues and plan to pressure Western developed nations for the necessary technology and financing to fight global warming.
A well-known, and recently contested, economic principle provides an interesting perspective on the climate change debate. In it's most (over)simplified sense, the
"tragedy of the commons" implies that one's individual self-interest can hurt the overall well-being of a group. In 1968, Garrett Hardin first offered the example of a group of herders who commonly owned a piece of land used for grazing. If each individual herder acted in their own self-interest, they would try to maximize their personal value by feeding as many of their cows as possible on the common land, even if it damaged or reduced the value of the land for the overall group. In the end, if every herder acted in this manner, they would permanently deplete the land in the long-term, thus allowing no one to benefit.
Although somewhat depressing, this dilemma seems to make sense in the light of human nature. Incidentally, Elinor Ostrom won the
2009 Nobel Prize in economics due in large part to her dispelling certain parts of this myth. By studying
smaller communities, such as farmers in Valencia, Spain who have managed water resources successfully for over 1,000 years, Ostrom has proven that collective groups can effectively manage unowned resources and coordinate an equitable system of use.
Ostrom's work is encouraging in that it evidences something other than pure, individual self-interest. Nonetheless, it's less reassuring when considering her research focuses on such coordination within much smaller groups than, say, the population of the entire flippin' world.
On the other hand, perhaps the lesson to be learned is that climate change will have to begin at the community level. How this can be done is the real trick, isn't it? Maybe India and China figured it out in their 48-hours of chit-chat. Let's hope...
