how can we avoid drought
Answers
Being mindful of the amount of water you use each day can be a powerful way to prevent droughts. Turning off the faucet while you brush your teeth, watering your garden early in the morning so less water evaporates, and installing low-flow plumbing fixtures all are good ways to prevent wasted water.
I HV answered it many times..but I will answer again for you..❤️
the prevention methods for droughts
Interlinking of national water resources (rivers). Water management can be much better that way.
Proper utilization and monitoring of available water resources. Water tax is not far away.
Proper monitoring of areas that are drought prone. The levels of water need to be updated hourly/daily. And a benchmark should be set for warning and alarms to trigger.
Agriculture and irrigation patterns need a change. Water intensive crops can’t be sown in water deficit areas.
Water transportation channels need to be properly maintained. Leakages are bad.
Water intensive industries (alcohol for example) should be away from water deficit regions.
Dams, check dams and other water storage mechanism need to be in place.
Filtration and purification processes should not waste water. For examples, Reverse Osmosis (RO) wastes water in the ration of 1:1. It makes no sense to promote RO. Promote bio sand filters or other similar equipment.
More work (scientific, academic, financial, innovation, coordination) needs to be done on Desalination processes. They still consume a lot of energy making it currently uneconomical.
Water meters need to be in place like electricity meters. Asking someone not to consume excess water has not given good results so far. Nobody counts water, a water meter will do that for them.
Population density needs to be monitored. Migration needs a check. Urban housing needs to have an upper limit. Obviously having a large no. of people consuming a very small resource will result into oblivion.
Have water trains on standby. Attach them to the units of disaster management teams. As soon as a possibility of drought arises in a region, the water train can reach there.
Deforestation should be prevented. Afforestation is badly required but where do you house all the population? And what about infrastructure development and economy? Sometimes deforestation is just inevitable and hence planning of where and how much forest to cut becomes very essential.
And judicious use of water. Awareness that wasted water won’t come back easily. Treat water at par with food.
These can be some basic steps to prevent droughts.
