内容提要:
Using the precipitation decline in downstream induced by the initial impoundment of the world’s largest hydroelectric dam in 2003 as a natural experiment, we identify differentiated patterns of adaptations to climate change by rural households’ initial endowments. Using gridded-monthly data and a difference-in-differences design, we confirm persistent decrease in spring precipitation in downstream of the dam, which is a hypothesis raised by previous hydrological studies. We further show that the decrease in precipitation leads to a 14 percent reduction in the yields of rice using a panel of over 40,000 rural households (1989-2014). In response to the continuous reduction in crop yields, small and subsistence-oriented farmers increase rice cropping area to maintain total output. In contrast, large and market-oriented farmers choose to migrate and find opportunities from less affected regions.
