Abstract

Recently, South Asian countries have committed their mitigation targets to the United Nations Framework Convention on Climate Change. This study examines the effectiveness of these efforts by developing a dynamic computable general equilibrium-water-energy (CGE-WE) model. Using the GTAP database version 9, it examines how different sectors respond to these policies in South Asia. Besides, it argues that an improved irrigation system can reduce the output losses caused by the mitigation policies. In a nutshell, the cost of improving irrigation system is USD 159.7 million in Bangladesh, 224 million in India, 9.1 million in Nepal, 38.5 million in Pakistan and 10.4 million in Sri Lanka. The proposed adaptation strategy can save more than USD 76.43 billion in the region after fulfilling the region’s commitment toward the global mitigation efforts.
