MEKONG DELTA — The Mekong provinces of An Giang and Kiên Giang have worked together to efficiently use water resources, combat natural disasters and cope with their aftermath.Kiên Giang and An Giang signed an agreement in 2013 for water resource management in the Long Xuyên Quadrilateral with support from the Integrated Coastal Management Programme (ICMP).
The agreement relates to water resource, flood and salinity control, water resources for irrigation and the responsibility of local authorities in implementing the agreement, Quảng Trọng Thao, deputy director of the Kiên Giang Department of Agriculture and Rural Development, said at a recent conference on water management in the two provinces in 2013-17.
Situated in the west of the delta, the 498,000ha Long Xuyên Quadrilateral is bordered by the Vĩnh Tế Canal, the Hậu River and Cái Săn Canal.
It is a major producer of rice and aquatic produce.
Under the agreement authorities have built the Tha La and Trà Sư flood control systems in An Giang Province’s Tịnh Biên District, a flood control dyke along National Highway 1 from Châu Đốc to Hà Tiên, a flood control system along the Hậu River, dykes and rainwater drainage and saltwater control systems along the coast, Grade 1 and 2 canal systems, an urban flood control embankment, and an embankment for agricultural production and flood control in An Giang and Kiên Giang provinces.
The water resource monitoring system includes hydrometeorology stations and stations for measuring water and alluvium quality.
Thao said in the past several years authorities in the two provinces have collaborated for the operation and maintenance of irrigation works that serve agriculture and foster socio-economic development.
The well-funded and -operated irrigation works in the Long Xuyên Quadrilateral have helped control flooding and saltwater intrusion and provide water for locals’ daily needs, irrigation and river traffic.
Now the region has over 85,000ha of land under rice, producing over five million tonnes of paddy a year, 13,598ha of ponds for shrimp farming, producing nearly 18,000 tonnes.
An Giang and Kiên Giang have also agreed on the annual release of water from the Tha La and Trà Sư dams between late August and early September to irrigate the summer-autumn and autumn-winter rice crops, mitigate flooding in the upper section of the river, wash away salt and disease-causing pathogens and deposit alluvium.
The two provinces have also jointly operated a drainage and saltwater control dyke system in the quadrilateral.
In 2018-20 a recent agreement on water management in the quadrilateral will be implemented, with Hậu Giang Province and Cần Thơ City joining Kiên Giang and An Giang.
They will work together to collect and share data on surface and ground water resources and the zoning and use of water resources in the quadrilateral.
Nguyễn Hữu Thiện, an expert on the Mekong Delta’s ecology, said: “In the complex situation caused by climate change, water is an essential resource. All fresh, salt and brackish water must be considered resources.” — VNS
