Scientists have proposed the construction of two reservoirs in Dong Thap and Hau Giang with capacities of 1 billion and 1.5 billion m3 of water, respectively, to provide fresh water to Southwestern provinces. Dr. Vo Van Hai from the Association of Economics and Management Science presented the plan to regulate water flow in the dry season and supply neighboring provinces.
The proposed location for the Dong Thap reservoir is near Tram Chim National Park, Tam Nong district, covering about 27,000 hectares and holding 1.5 billion m3 of water. The second reservoir in Hau Giang, located near Lung Ngoc Hoang nature reserve, is set to hold 1 billion m3 of water. Both projects have the dual function of water storage and fire prevention in the reserves.
However, the construction of these reservoirs faces technical challenges in dealing with soft ground, water distribution, and environmental protection. Considerations for land clearance, people’s livelihoods, and economic impacts also need careful planning. The agricultural sector plans to invest significantly in freshwater solutions for the region until 2030 to meet growing water demands.
Experts emphasized the need for caution while discussing the proposal for reservoir construction near nature reserves to ensure harmony between human needs and environmental conservation laws. Suggestions were made for building smaller-scale reservoirs as a more feasible and cost-effective solution that would minimize environmental impact while still meeting freshwater demands efficiently.
The workshop highlighted the importance of technical analysis and policy support in managing water resources effectively and sustainably. Scientists and policymakers were encouraged to collaborate closely to address the freshwater challenges in the Mekong Delta region by ensuring that their efforts are aligned with sustainable development goals (SDGs).
