Abstract

The Bay Nui highland of An Giang province includes Tri Ton and Tinh Bien district which owns a huge potential for agriculture developing (such as vegetables, fruits, medicinal plants with high tech methods) and concentrated grazing. Though, due to complex climate change, irregular distribution in space and time of water resources and unusual, harsher flow regime lead to flood in the rainy season, drought in the dry season and seriously water scarcity for production as well as living. At the moment, the agricultural restructuring of Tri Ton, Tinh Bien particularly and An Giang province in general is developing strongly and towarding high tech agriculture. This paper presented to caculate water demand and water balance specifically in this area not only assessing the status of water resources, ability of water demand satisfaction in irrigation systems but also considering them as a basis for proposing water storage remedies for highland to serve the development of agricultural production, contribute to improve local livelihoods, economy and society.
