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

Citizen Matters looks at what the city should do to manage its water better.

A recent BBC report projected that Bengaluru will run out of water soon.

Yes, it was a superficial list of cities that already have water problem. It just pronounced the harsh verdict without any in-depth analysis of the factors involved. That’s like taking a casual look at an emaciated man and saying, “he is going to die soon”.

There are various reasons why India’s small and marginal farmers are unhappy.

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. Agricultural productivity levels have been stagnant for the past 10 to 15 years. An estimated 70 percent of the country’s arable land is prone to drought, 12 percent to floods, and 8 percent to cyclones.

An innovative project makes rainwater harvesting easier and more effective in certain areas of Mewat village with increased groundwater salinity.

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. Depletion of groundwater changes the flow (both direction and velocity) of the groundwater which may cause the inflow of polluted water into the freshwater aquifer from surrounding areas.

Sustainable agro-ecological farming is one way to overcome the limitations of conventional farming. Green College shows us how to do it.

Pitidri is a nondescript village that dots the rainshadow area of Purulia district in West Bengal. Droughts are common here even when the area is endowed with above average rainfall of over 1300 mm a year. Until some time ago, Urmila Mahato, a 42-year-old farmer from Pitidri had been struggling to ensure her family’s food security. Her family could barely sustain on the 18 quintals of paddy her small farm of two acres could produce in a year. Only one acre of her farm could be used for seasonal farming of vegetables due to lack of irrigation facilities.
