Abstract
While the existing literature has well documented the effects of climate change on migration, very little is known about the moderating impact of local non-farm income. In this context, the paper combines real time weather data provided by Indian Meteorological Department with a very rich household data on Indian states belonging to the eastern and semi-arid tropic regions collected by ICRISAT to investigate whether farmers always resort to migration or take it up as a second-best option only after they fail to diversify locally. Using recursive econometric model, it is observed that households first try to diversify their income by engaging in local non-farm activities and availability of local non-farm income further moderates the effect of climate change induced yield loss on migration. High levels of migration may result in welfare loss and affect urban sustainable development, and the decision to migrate is often challenging as it necessitates leaving behind social and community networks. Therefore, our findings offer valuable insights and discusses important policy recommendations towards improving the access to local non-farm activities.
期刊介绍:
The Journal of Policy Modeling is published by Elsevier for the Society for Policy Modeling to provide a forum for analysis and debate concerning international policy issues. The journal addresses questions of critical import to the world community as a whole, and it focuses upon the economic, social, and political interdependencies between national and regional systems. This implies concern with international policies for the promotion of a better life for all human beings and, therefore, concentrates on improved methodological underpinnings for dealing with these problems.
