Ganga

To provide the background hydrological information for the assessment of environmental flow requirements at four selected ‘Environmental Flow’ sites, a hydrological model was set up to simulate the catchment in the present state (with water regulation  infrastructure) and to generate the natural flows (without water regulation infrastructure).

The Level-I Laboratories are located at 258 field water quality monitoring stations on various rivers of India where physical parameters such as temperature, colour, odour, specific conductivity, total dissolved solids, pH and dissolved oxygen of river water are observed.

Kosi is known as the sorrow of Bihar due to its frequent and often disastrous floods. The major geomorphic units of flood-inundated area in Kosi fan (terrain of Kosi river in India) are sand bars in the form of inter-connected drainage networks, an ox-bow lake and its meandering cut-off and imprint.

This report presents the results based on climate change scenarios and identifies potential adaptation strategies. The study is part of the ‘Climate Change Impacts on Freshwater Ecosystems in the Himalayas’ (CCIFEH) project, a joint initiative of WWF-India and WWF-Nepal, supported by WWF-Netherlands and aims to study and understand climate change impacts on freshwater ecosystems, livelihoods and the economy.

Change in climate conditions and the frequency of natural disasters in recent times has made it imperative to find lasting adaptation solutions for the agriculture sector. Given that almost 60 per cent of the country’s population relies on this sector for its livelihood and that it contributes approximately 15.7 per cent of India’s GDP, an analysis of changes which could impact crop yields and subsequently lead to an instable food security scenario is necessary.

The River cleaning project is to the tune of US $ 1 billion (approximately Rs 4,600 crore) loan and credit that will form part of the Bank’s long-term support for cleaning the Ganga River. Two Biodiversity Conservation agreements are for a credit of US$15.6 million and US$8.14 million grant.

On this occasion, Sh Jairam Ramesh , Minister of State for Environment and Forest Minister said, “Two protected areas, one each in Uttarakhand and Gujarat, will put in place a complete new model of managing the protected areas while safeguarding the livelihoods of local communities. So far local community was looked as enemies of protected areas, but this has to be changed. We have to make local communities full partners in the protection and regeneration of these protected areas. These new models will be applied in other areas of the country.” Giving details of cleaning operations of last few years, the Minister said, “The objective of Ganga project is ‘by 2020 no municipal sewage and industrial effluent will be let into the river Ganga without treatment’. With the help from the World bank, we are taking a big step forward in achieving the Mission Clean Ganga”.

The Ganges

The data has been collected over a period of many years from 39 water quality monitoring stations along the main river and 102 stations on its tributaries which were setup in 2008/09.

The study focuses on the parameters for dissolved oxygen, (DO), biochemical oxygen demand (BOD) and faecal coliforms (FC) as these indicate the biological health of the river. The period of study for the river Ganga is 1999-2008. The study finds that most of the water quality parameters studied do not meet the standards.

This approach is based on the integration of readily available remote sensing, national crop productivity and land use statistics and weather data.
