Consolidated learning from the salinity ingress prevention program in Gujarat India
The socio-economic and environmental problems caused by the groundwater salinization in the coastal area of Saurashtra, India, were acknowledged already in the late 1970s. Since then, the government, NGOs and the local people tried to stop, reverse and cope with groundwater salinization in a joint program. This study looks at the effects of this long-term program and consolidates learning by taking a groundwater resources management approach. For 3 river basins, a groundwater flow and solutes transport model is developed to estimate the effects of various existing and proposed measures and scenarios. The study illustrates the importance of using a groundwater resources management approach to design and optimize effective and efficient measures to counter groundwater salinization.
