This study evaluates the impacts of climate change on maize yields in Tamil Nadu, and assesses the efficacy of adaptation strategies, using a novel multi-climate, multi-crop model approach based on AgMIP Protocols (www.agmip.org). While the climate models displayed consistent changes to rainfall and temperature, substantial uncertainty exists between the different climate-crop model responses that warrant further study. Adaptation strategies proved beneficial under a current climate context, but showed diminished efficacy under future climate conditions. We recommend that future work focus on identifying the main sources of climate-crop model uncertainty, and that additional work may focus on more transformative adaptation measures.

Abstract


This study evaluates the impacts of climate change on maize yields in Tamil Nadu, and assesses the efficacy of adaptation strategies, using a novel multi-climate, multi-crop model approach based on AgMIP Protocols (www.agmip.org). While the climate models displayed consistent changes to rainfall and temperature, substantial uncertainty exists between the different climate-crop model responses that warrant further study. Adaptation strategies proved beneficial under a current climate context, but showed diminished efficacy under future climate conditions. We recommend that future work focus on identifying the main sources of climate-crop model uncertainty, and that additional work may focus on more transformative adaptation measures.
