Climate-induced crop failure and crop abandonment: What do we know and not know?

Our understanding of climate-induced crop failure and crop abandonment is limited at present. This study surveyed theoretical and empirical literature on climate-induced crop failure and crop abandonment. We reviewed widely used models of crop abandonment decisions and emerging evidence of determinants of crop failure and crop abandonment. While most of the studies reviewed focus on crop failure, a very limited body of work examines crop abandonment decisions, with climate variables emerging as the key determinant. The review also highlights both theoretical and empirical models popular in the literature. We link crop failure and crop abandonment to weather variables and the resultant agricultural productivity loss and possible risk management strategies, highlighting policy implications and areas for future research.
