Performance Assessment of Irrigation Schemes and Water Pollution Issues Raised in the Red River, Vietnam

Irrigation schemes management in Red River Delta, Northern Vietnam has an extreme significance to ensure the multi-objective water supply and the health of the Red River. This study is drawn upon mostly primary data sources including results of water supply assessment of economic industries and the status quo of hydraulic works (pumping station, canals, gates, regulating reservoirs, etc.) along the Red river (study area inside the territory of Vietnam), then compare the results against the value of water supply capacity of irrigation schemes in the context of effectiveness of hydraulic works has not yet achieved as original designs (approximately 60%). From that point, identifying the relationships between - trade off - the water supply and healthy of the Red river. The results of the comparison show that the water supply for agriculture production will increase dramatically in 2020 approximately from 8 bill.m3/year compared to actual demand of about 13.65 bill.m3/year. And, more irrigation water may be more harmful for the Red river’s health, which is absolutely correct in the context of irrigation schemes also supply for other sectors such as industry, drinking water, aquaculture farms, etc. The results of this study are conclusive evidence to promote the implementation of a number of water policies in the Red River Delta.
