Harness the five sources of water: Prof M S Swaminathan
Today, March 22, is World Water Day. In the anthropocene era water is going to be the most serious constraint for agriculture, industry and domestic purposes. Hence it is appropriate that this year’s theme is “Why Wastewater?”. There are five sources of water and we should consider all of them and use them conjunctively. First, is rain water; water harvesting both in the farm and in the home should become mandatory. Second, is river water, we should be shared equitably by the upper and lower riparian’s. Third, is the water coming from recycling of wastewater. Here again wastewater recycling through bioremediation must become mandatory. Fourth, is water coming from snow fall, dew etc .must be consumed. Finally the sea water constitutes 97% of the world’s water and the sea water farming and below sea water farming should be popularised. If all these sources of water can be harnessed carefully and utilised efficiently and equitably, all nations can hope for sustainable water security system.
M S Swaminathan Research Foundation (MSSRF) established in 1988 is a not-for-profit trust. MSSRF was envisioned and founded by Professor M S Swaminathan, agriculture scientist with proceeds from the First World Food Prize that he received in 1987.
