The present study develops an integrated assessment model (IAM) for food security under climate change South Asia. For IAM, initially, econometric is estimated that identifies the impact of on crop yields, using historical relationships between temperature, precipitation, and production cereals. Subsequently, future projections have been collected temperature precipitation from models Coupled Model Inter-comparison Project Phase 5 (CMIP5), previous applied to obtain implied cereal yields changes. Then, yield variations are fed into a multiregional Global Trade Analysis (GTAP) model, calibrated GTAP 9 database, taking form decreases in factor-augmenting productivity grains sector. Further, evaluates effects individual Asian country. results indicate production, increases prices, consumption, thus affects welfare. fiscal policy responses investigated combat problem security. It revealed these two policies fail compensate damage all selected countries.
