In Meghalaya, a 2OO year old system of tapping stream and spring water by using bamboo pipes is prevalent. About 10-20 litres of water enters the bamboo pipe system, gets transported over hundreds of meters, and finally reduced to 20-80 drops per minute at the site of the plant.

About 10-20 litres of water enters the bamboo pipe system, gets transported over hundreds of meters, and finally reduced to 20-80 drops per minute at the site of the plant. Bamboo pipes are used to divert perennial springs on the hilltops to the lower reaches by gravity.

(l) Rooftop rainwater harvesting is the most common practice in Shillong, Meghalaya. Nearly every household in the city has a rooftop rainwater harvesting structure. Around 15-25 per cent of the total water requirement of the household comes from rooftop water harvesting.
(ii) Rooftop harvesting was common across the towns and villages of the Thar. The rainwater that falls on the sloping roofs of houses is taken through a pipe into an underground Tanka built in the main house or in the courtyard. However, sadly the practice of rooftop rainwater harvesting is on the decline as plenty of water is available due to the perennial Rajasthan Canal.

(a) Rainwater harvesting is a technique of increasing the recharge of groundwater by capturing and storing rainwater by constructing structures, such as dugwells, percolation pits, checkdams.
(b) Keeping into view the disadvantages and rising resistance against the multipurpose projects, water harvesting system is considered a viable alternative both socio-economically and environmentally.
(c) Rainwater harvesting system was used in ancient India as given below:
(l) In hilly and mountainous regions, people built diversion channels like the ‘guls’ or ‘kuls’ of the western Himalayas for agriculture.
(ii) ‘Rooftop rainwater harvesting’ was practised to store drinking water, particularly in Rajasthan.
(iii) ln the flood plains of Bengal, people developed inundation channels to irrigate their fields.
(iv) In arid and semi-arid regions, agricultural fields were converted into rain fed storage structures that allowed the water to stand and moisten the soil like the ‘Khadins’ in Jaisalmer and’ Johads’ in other parts of Rajasthan.
(u) In Bikaner, Phalodi and Barmer, almost all the houses had underground tanks for storing drinking water.

It is a Non-Government Organisation that mobilised tribal people, farmers, environ-mentalists and human rights activists against the Sardar Sarovar Dam being built across the Narmada river in Gujarat. In the beginning, the objects of the Andolan were environmental issues related to trees that would be submerged under the dam water. Now its aims are to enable poor citizens, especially the displaced persons to get full rehabilitation facilities from the government because such projects lead to large scale displacement of local communities. They have to give up their land, Livelihood and their meagre access and control over resources for the Greater good of the nation.
