Water use efficiency in irrigation systems of Vietnam
Tóm tắt
Water use efficiency in irrigation system is mainly determined based on irrigation efficiency and water productivity. According to the World Bank, water productivity in Vietnam attains at $2.57/m3, approximately one-tenth of the global average of $19.42/m3. The agricultural sector consumes over 80% of the total water demand, however, its contribution to the national gross domestic product is merely 13.96%. Therefore, improved water use efficiency in the agriculture sector will increase the value of water to the economy. This paper addresses water use efficiency in different irrigation schemes as well as evaluates the aspects that affects the water use efficiency. Results from this research are considered fundamental inputs for proposing solutions to promote the water use efficiency in Vietnam
