Traditionally, water was seen as a responsibility of citizens and the community collectively took the responsibility of not only building but also of maintaining the water bodies. Since independence, the government has taken control over the water-bodies and water supply. This, over time, has led to the neglect of the water bodies and catchments areas.

Using water sustainably in agriculture: Increasing productivity and farm income
Better water management in agriculture will go a long way in improving our crop productivity and thereby total output to feed the masses, not only of India but also of other parts of the world. Posted on 29 Aug, 2009 01:29 PM

Agriculture is a vital sector in India with about 60% of the population engaged in agricultural vocations and contributing to about 30% of the GDP. It consumes about 80% of water used in the country and 76% of the net irrigated area in the country is from ground water sources.

Pani panchayat in Orissa: The practice of participatory water management
This paper published in the journal Development explores the impact of new institutions in participatory water management such as Pani Panchayat (PP) in Orissa in the context of equity and access to water, transfer of property rights and handling water conflicts. Posted on 29 Aug, 2009 11:32 AM

This paper, published in the journal Development argues that new policy interventions such as Pani Panchayat in Orissa, India ignore the local socioeconomic contexts and fail to ensure co

Impact of climate change on the Mahanadi river basin
The Mahanadi river basin is one of the most vulnerable to climate change and variations in temperatures and precipitation regions. Posted on 28 Aug, 2009 02:56 PM

The Mahanadi River delta plain covers 0.9 x 10 km and lies between 85 40' : 86 45' E and 19 40' : 20 35' N. The catchment area of the river covers 1.42 x 10 km. The sediment yield of the Mahanadi catchment is around 200-400 tonnes/km. It has an average annual rainfall of 1572 mm and 70% of this during the SW monsoon season.

Effect of climate change on river Kosi and its basin
Considering the vulnerability of the Kosi's basin, the melting glaciers will acerbate the problem a hundredfold. The melting glaciers will release much more water than normal in a short time thus creating a flood situation. Posted on 28 Aug, 2009 02:46 PM

Kosi is one of Ganga's largest tributaries and in turn is fed by 7 tributaries - Sun Koshi, Dudh Koshi, Indravati, Tama Kosi, Likhu, Arun, and Tamar. These tributaries encircle Mt Everest from all sides and are fed by world's highest glaciers. The river drains a total area of 69,300 sqkm upto its confluence with Ganga. The river basin stretches 54,000 sq.kms.

Effect of climate change on the Ganga-Brahmaputra delta regions
The Ganga-Brahmaputra-Meghana delta belt comprises of 105,000 sq. kms of which 2/3rds is in Bangladesh. The Ganga-Brahmaputra-Meghana system has the largest catchment area of 1,100,000 km². The delta region is particularly vulnerable to seasonal floods, heavy run-offs from melting snows, and tropical cyclones in the Bay of Bengal. Inspite of this, it is one of the most thickly populated regions on Earth. Posted on 28 Aug, 2009 02:28 PM

The delta belt is home to approximately 125-140 million people. And over 300 million people are supported by the delta. The density of population in the Delta region is 200 people / sq.km. making it one of the densest regions in the world.

The delta region is a high-rainfall region and receives 60-80 inches of rainfall every year.

Impact of climate change on major river basins in India: The Indo-Gangetic-Plains
The effect of climate change on the Indo-Gangetic-Plain region will primarily be by the glacier melting impacts and heat waves and extreme climates Posted on 28 Aug, 2009 02:14 PM

The Indo-Gangetic Plains, formed by the drainage systems of the rivers Indus and the Ganga, stretch across the countries of Bangladesh, Nepal, India and Pakistan covering approximately 401.72 million hectares of land.
