A little bit of shrimp farming is OK, environment economists say

mangroveThe choice between total devastation and total conservation of mangroves is a false one, according to analysis published today in Science. With a team of colleagues, Edward Barbier, a professor of economics at the University of Wyoming, studied the effects of conversion to shrimp aquaculture on a 10 km stretch of Thailand’s mangrove. Because mangroves play such a pivotal role in coastal protection from storms, hurricanes and tsunamis, their economic value is high (compared to the potential cost of disaster recovery in their absence). However, these benefits are only felt locally, whereas the profits from shrimp farms line pockets around the world. Barbier’s group found that a small amount – no more than 20 percent – of farming makes little difference to the protective powers of the mangrove: it’s only at higher levels of degradation that things start to bite. Understanding the impact of shrimp farming properly could help conservation managers achieve a delicate balance between ecosystem protection and keeping the fat cats happy.
