Southwest Monsoon provides about 75% of our water and yet we have not learnt how to manage that rain water, without creating avoidable flood disasters, without using submergence as weapon to displace people as is being attempted in case of Sardar Sarovar Project in Gujarat, without allowing water to flow to Pakistan, which is against all the rhetoric of the top most government persons and without the needless push for more big dams or interlilnking rivers or such mega centralised projects and programs? If we go through this week’s DRP News Update, it does not seem like we have. All the contrary elements are there for all to see.
It is certainly possible to manage the rain better so that more of it is available beyond the monsoon in a decentralised manner, as decentralised as the rainfall itself. The elements of it all well known: harvest rain where it falls, recharge groundwater, create local water systems, desilt existing such systems, protect wetlands, forests, increase soil’s capacity to hold moisture through increasing carbon/ organic conent of the soils (we know how this can be achieved), use the created large reservoirs judiciously, ensure all the dams in a basin are filled up simultaneously and not sequentially, ensure water flow in the river for maximum period as that will also help recharge groundwater, reduce deforestation in the catchments, increase forest area in the catchments where possible, protect local water systems everywhere including Urban areas, protect flood plains and ensure rivers have capacity to carry floods that it is required to carry, have better and more accurate rainfall forecasts (including riverbasin wise/ sub basin wise forecasts), coordinated actions across river basins and states. There is some minor improvements here and there as we see in this bulltin, but no major change.
It’s more optimal rain water management that will help better water security, sustainable water availability, food production, livelihoods and agricultural security, among others. What is the road map to learn this and learn fast? There is no immediate light to the end of the tunnel.
