India is facing huge crisis of water with rivers drying up, even when there are floods during rains.
There are several reasons for this, but the most important reasons is massive deforestation in hills. Most of the rivers have their origins from hills, where water seepage from roots of trees accumulate and form into stream becoming river downstream. Thick forests in hills obstruct the rainwater to flow downstream. Branches and stems of trees absorb a large part of rainfall, which continue to seep even after rains stop. This ensures water in rivers throughout the year. Good flow of water also does not allow the dust to settle in riverbed, thus keeping the depth intact.
Massive deforestation in hills has simply disturbed the ecology. Moreover, filling up of ponds, which helps storage of surplus rainwater to be used later in lean season. Most of highrises today ensure that entire surface is covered by concrete and the garden is created by using artificial soil and grass. All these ensure that rainwater is not allowed to be stored or absorbed by the trees.
This is the time, when elites both by way of money or education mostly living in cities think over it. They should force highrises to have proper rain-water harvesting system, so that groundwater level is maintained. They should ask the builder about the safeguards for this. They may also ask for fruit trees and kitchen garden within the complex to ensure greenery and absorption of rain water. Further, they should take a vow to plant a tree, whenever they are on a tour, specially to hills.
Small baby steps by citizens can do wonders.
