Bengal Basin

This case study in National Institute of Science Communication and Information Resources (NISCAIR) by the Central Institute of Mining and Fuel Research (CIMFR), Dhanbad and the Geo-Environment Division (Environment Management Group) deals with groundwater quality assessment of Jharia coalfield area of West Bengal. The physiochemical characteristics of groundwater of the upper catchments of the coalfield were studied to evaluate the water quality.

Bangladesh typically experiences a mild winter from October to March; a hot, muggy summer from March to June; and a warm, rainy monsoon from June to October. By early July 2011, rains had already transformed northeastern Bangladesh.

Beginning in 2005, WWF-India has conducted dozens of personal interviews to record how climate change impacts people's lives here and now. These perceptions demanded that s

India is the largest user of groundwater resources in the world. It is estimated that approximately 230 cubic kilometers per year is used annually, this is more than a quarter of the total world consumption from this resource.

It is in this context that this World Bank report looks at the reasons for this quantum of groundwater usage.

The report delves into socio-economic and political reasons and looks at policies which inadvertently promote so much extraction. The report also analyses various attempts to manage this resource. These attempts range from government and international agency efforts directed to grassroots mobilisations. Finally the report comes out with suggestions to deal with this crisis.

The paper by Challenge Programme on Water and Food (CPWF) attempts to assess and improve water productivity in conservation agriculture systems in the Indus-Gangetic basin, in which during the past 40 years an intricate mosaic of interactions between man & nature, poverty & prosperity and problems & possibilities has emerged. Rapid expansion in agricultural water use is a common theme across these interactions and access to water is central to the livelihoods of the rural poor.

The paper by the Challenge Programme on Water and Food (CPWF) - Basin Focal Project provides a brief situation analysis related to water, agriculture & poverty, water resources, water productivity, institutional aspects and opportunities & risks related to the development of the Indo-Gangetic basin (IGB). Management of IGB water resources presents some formidable challenges and, therefore, steps must be taken towards integrated management of the IGB’s water and land resources in order to ensure the future sustainability of all production and ecosystems in the basin. 

This report deals with the social conflicts emerging out of the encroachments owing to the change in course of the Ganga upstream and downstream of the Farakka barrage. The barrage was built with the intention of diverting water into the Hugli river with a view to flush the sediment load into the deeper part of the estuary and revive the navigational status of Kolkata port. During the last three decades of its operation, the silt-management in the barrage was given scant or no attention. The sediment movement in the tidal estuary of Hugli is a function of a complex fluvial system that can hardly be governed by inducing 40000 cusec of water.

This paper by Centre for Studies in Social Sciences and Jadavpur University, aims at explaining the factors that determine private investment in groundwater irrigation in West Bengal. It also addresses the issues pertaining to institutional arrangements, particularly provision of facilities by the government. The study, largely empirical in nature, is based on data collected from surveys conducted in close to one thousand moujas (villages) spread across the major agro-climatic zones in West Bengal. It begins with a descriptive account of the changes in the agricultural scenario in West Bengal over the last thirty years. The research questions are discussed and the econometric methodology presented.

A widespread view that is gaining ground is that climate related migration could evolve into a global crisis by displacing a large number of people from their homes and forcing them to flee. Christian Aid postulates that a billion people could be permanently displaced by climate change related phenomenon such as droughts, floods and hurricanes (Christian Aid 2007). The fourth assessment report of the Intergovernmental Panel on Climate Change (IPCC) mentioned the “potential for population migration” due to increase in the number of areas affected by droughts and an increase in the intense tropical cyclones activities (IPCC 2007: 18). In particular, it seems likely that significant numbers of people will be displaced, either temporarily or permanently, from their homes as a consequence of global warming (Stern 2006). Available scientific evidences indicate that a large number of people might be displaced due to climate change. However, much of the literature on this issue refers to the question of whether the   people forced to migrate as a consequence of climate change should be described as climate refugees. There is no internationally agreed definition of the term “climate refugee” and the extent to which these displaced persons constitute a separate identifiable group. Although it is now widely recognised that climate change will significantly adversely affect India, there are few studies available on how climate change is going to affect the migration of people. It has been asserted that 70,000 people out of the 4.1 million living in the Indian part of the Sundarbans islands would be rendered homeless by 2020 (EPW, 6 June 2009).
