Application of the Ricardian Technique to Estimate the Impact of Climate Change on Smallholder Farming in Sri Lanka

摘要: This study applies the Ricardian technique to estimate effect of climate change on smallholder agriculture sector in Sri Lanka. The main contribution paper is use household-level data analyze long-term impacts farm profitability. Household-level allows us control for a host factors such as human and physical capital available farmers well adaptation mechanisms at level. We find that non-climate variables explain about half variation net revenues. However, our results suggest will have significant impact In particular, reductions precipitation during key agricultural months can be devastating. At national level, revenues between −23% +22% likely depending scenario simulated. These vary considerably across geographic areas from losses 67% gains more than double current largest adverse are anticipated dry zones North Central region South Eastern regions On other hand, intermediate wet benefit, mostly due predicted increase rainfall.
