Potential impacts of climate change on agricultural production in the Long Xuyen Quadrangle, Vietnamese Mekong Delta

Climate change and its impacts have become a serious and concerning global issue. The Vietnamese Mekong Delta, is identified as one of the deltas most adversely affected by climate change. This study aims to assess the potential impacts of climate change on seven major agricultural production systems in the Long Xuyen Quadrangle region within the Vietnamese Mekong Delta. Utilizing the Analytic Hierarchy Process (AHP) in conjunction with calculating climate change impact indices, the research classifies the degree of climate change impact on agriculture, aquaculture and forestry. The study results indicate that different agricultural production systems will experience varying impacts from climate change. For rice cultivation, flooding and drought are identified as the factors with the highest impact. Factors such as temperature increase, changes in rainfall and salinity intrusion have the most significant effects on aquaculture. In contrast, cultivated and natural forests in the research area are less affected by climate change. This assessment outcome could be highly valuable for policymakers in developing local agricultural development plans.
