Rainwater Harvesting

Rainwater harvesting (RWH) is a simple method by which rainfall is collected for future usage. The collected rainwater may be stored, utilised in different ways or directly used for recharge purposes. With depleting groundwater levels and fluctuating climate conditions, RWH can go a long way to help mitigate these effects. Capturing the rainwater can help recharge local aquifers, reduce urban flooding and most importantly ensure water availability in water-scarce zones. Though the term seems to have picked up greater visibility in the last few years, it was, and is even today, a traditional practice followed in rural India. Some ancient rainwater harvesting methods followed in India include madakas, ahar pynes, surangas, taankas and many more.

This water conservation method can be easily practiced in individual homes, apartments, parks, offices and temples too, across the world. Farmers have recharged their dry borewells, created water banks in drought areas, greened their farms, increased sustainability of their water resources and even created a river. Technical know how for the rooftop RWH with direct storage can be availed for better implementation. RWH An effective method in water scarce times, it is also an easily doable practice. Practical advice is available in books written by Indukanth Ragade & Shree Padre, talks by Anupam Mishra and other easy to follow fun ways

Seeds of discontent
There are various reasons why India’s small and marginal farmers are unhappy. (not verified) posted 3 years ago

Small farmers are the key to ending poverty and hunger and promoting sustainable development. In India, small and marginal farmers—those who work on less than two hectares (five acres) of land—constitute 80 percent of all farm households, 50 percent of rural households and 36 percent of the total of all households. Sadly, the plight of these farmers is very distressing.

Harvesting rainwater effectively
An innovative project makes rainwater harvesting easier and more effective in certain areas of Mewat village with increased groundwater salinity. Amita Bhaduri posted 3 years 2 months ago

One of the major causes of deterioration of water quality is the increase in overall salinity. Total hardness and the presence of materials like fluoride, nitrate, iron, arsenic, and toxic metal ions determine salinity levels in groundwater. With the demand for groundwater growing rapidly, its exploitation is also accelerating which causes depletion.

The innovation was introduced in a government school building in Untka village located in Mewat district of Haryana.
