Thirteenth International Conference on Climate Change: Impacts & Responses

Abstract

This paper examines the salted water intrusion (SWI) adoption in Central Coastal region of Vietnam. We evaluate the impact of SWI adaption options on farmer’s livelihoods, using cross-sectional survey data of 414 farmers in Thua Thien Hue and Quang Nam province. Propensity-score-matching (PSM) techniques is applied to solve problem related to “self-selection into treatment”. The findings reveal a robust and significant impact of SWI adaption methods on economic indicators (crop productivity, net farm income) and social indicators (rate of kid going to school and food security). The results confirm that there is considerable heterogeneity in implementing SWI adaptation options of farmers in study area. We find that out of five adaption methods, four (vegetable, papyrus, shrimp and lotus-fish) are noted to have a quite significant income –enhancing, mainly thank to higher profits. Moreover, the household who apply these four methods have significantly higher rate of kid going to school (by 15%, 8%, 22% and 57% respectively) and ensure more food secure. Method of applying new varieties rice is recognized to have income- decreasing due to lower yield and insignificantly positive effect on social issues. The significant of results are tested by bootstrap to ensure robustness in our study.
