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.

气候变化的适应和减缓政策：动态 CGE-WE 模型

近期，南亚国家已将减排目标提交给《联合国气候变化框架公约》。本研究通过开发动态可计算一般平衡水能 (CGE-WE) 模型来检验这些努力的有效性。使用 GTAP 数据库第 9 版，它检查了不同部门对南亚这些政策的反应。此外，它认为改进的灌溉系统可以减少缓解政策造成的产出损失。简而言之，改善灌溉系统的成本在孟加拉国为 1.597 亿美元，印度为 2.24 亿美元，尼泊尔为 910 万美元，巴基斯坦为 3850 万美元，斯里兰卡为 1040 万美元。拟议的适应战略在履行该地区对全球减缓努力的承诺后，可为该地区节省超过 764.3 亿美元。
