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

Watershed management is not just to harvest and store water but also to create democratic processes at the village level and enable inclusive, sustainable development that meets the people's needs.

In India, although we have approximately four months of monsoon (which is basically 45 days of effective rainfall), in drought prone areas, there are only 10-15 days of harvestable rain in the entire season. If you don't get enough rain during those days, it's a cause for worry.

To make access to water adequate and equitable, the focus must shift from water sources to water resources. Science, community participation and cooperation, are key to addressing our water woes.

A growing demand for water implies the need for an improved understanding of our resources, and the ability to manage that demand in an equitable and sustainable way.

Wells, not dams, have been the temples of modern India

India is a groundwater economy. At 260 cubic km per year, our country is the highest user of groundwater in the world - we use 25 percent of all groundwater extracted globally, ahead of USA and China.

Studies reveal that efforts at guinea worm eradication have triggered the spread of hydrofluorosis in Rajasthan.

Up until two decades ago, the main sources of drinking water in Rajasthan included surface water from perennial ponds, reservoirs, lakes, dams, rivers and streams with borewells and tubewells used sparingly and only in remote areas. All this changed when guinea worm infections started appearing in the state.

Water conflict in Rajasthan’s Alwar district is not just between upstream and downstream users; it is also between users with domestic, agricultural and industrial needs.

Lewari, a village located around 17 km from Alwar in Rajasthan, is the site of a water conflict these days. “The production of Jayanti jaljeera, haazme ka lalantop drink (a digestive drink) has left our village parched,” says Nanak Singh, a resident. Singh is referring to the excessive quantity of water being used for manufacturing a digestive drink by a factory located in his village. The indiscriminate use of a lake bed in the village for industrial use has led to groundwater scarcity during peak summer months.
