Abstract

Drought and salinity intrusion (DSI) increasingly threaten agriculture and aquaculture in coastal regions. Focusing on the Vietnamese Mekong Delta (VMD), we examined how DSI from 2000 to 2020 influences rice cropping, aquaculture area, and rice yield across seven coastal provinces. discharge and salinity monitoring, combined with satellite-derived land use data and yield validation, revealed the highest DSI impacts during the 2010-2011, 2015-2016, and 2019-2020 dry seasons. Local governments employed strategies such as drought-tolerant rice, improved irrigation, and revised cropping schedules to mitigate losses, yet further investments remain vital. Our findings provide evidence-based insights for managing DSI and strengthening agricultural resilience in the VMD and other vulnerable deltas worldwide.

摘要

干旱和咸潮入侵日益威胁着沿海地区的农业和水产养殖业。以越南湄公河三角洲（VMD）为研究对象，我们考察了2000年至2020年期间的干旱和咸潮入侵对七个沿海省份的水稻种植、水产养殖面积和水稻产量的影响。流量和盐度监测，结合卫星衍生的土地利用数据和产量验证，揭示了2010 - 2011年、2015 - 2016年和2019 - 2020年旱季期间干旱和咸潮入侵的影响最为严重。地方政府采取了耐旱水稻、改善灌溉和调整种植时间表等策略来减轻损失，但进一步的投资仍然至关重要。我们的研究结果为管理干旱和咸潮入侵以及增强越南湄公河三角洲和全球其他脆弱三角洲的农业复原力提供了基于证据的见解。
