text: When sufficient salt export is not taking place from a river basin to the sea in an attempt to harness the river water fully, it leads to river basin closure, and the available water in the downstream area of the river basin closer to the sea becomes saline and/ or alkaline water. Land irrigated with saline or alkaline water gradually turns into saline or alkali soils. The water percolation in alkali soils is very poor leading to waterlogging problems. Proliferation of alkali soils would compel the farmers to cultivate rice or grasses only as the soil productivity is poor with other crops and tree plantations. Cotton is the preferred crop in saline soils compared to many other crops. Interlinking water surplus rivers with water deficit rivers is needed for the long-term sustainable productivity of the river basins and for mitigating the anthropogenic influences on the rivers by allowing adequate salt export to the sea in the form of environmental flows.
