Định hướng hiện đại hóa hệ thống thủy lợi phục vụ chuyển đổi, phát triển nông nghiệp bền vững tại các tiểu vùng sinh thái vùng đồng bằng sông Cửu Long

Abstract

Vietnamese Mekong Delta is a region with typical natural conditions and water resources, forming three sub-zones of fresh, brackish and saline ecology, being the key agricultural production, playing an important role in our country's economy. In recent years, drought, saline intrusion and flooding in the area have been changing rapidly. The main causes of this phenomenon are climate change - sea level rise, upstream development and internal development of the region. In order to serve agricultural production and community, hydraulic works in the area have been invested and built for many years, making important contributions to flood and saltwater intrusion control,... For the adverse impacts that are facing, current hydraulic works have not been able to keep up with the requirements of production development and living activities, especially in the requirements of conversion, sustainable agricultural development in the sub-zones according to The Resolution 120/NQ-CP of the government issued on 17/11/2017. The paper analyzes specific problems and challenges, orienting a number of key solutions, including structural and non-structural solutions to modernize hydraulic works for transformation and sustainable agricultural development in the secological sub-regions of the delta.
