South Bihar Plains

A practical paper that addresses vital gaps in water quality monitoring and institutional weakness, focuses on the role of access and interventions in severely contaminated areas and calls for a drastic shift in the monitoring and intervention strategy to address safe water provision for rural Bihar

This presentation  highlights the grave water situation in Bihar in the context of the emerging water quality and quantity issues that the world and especially developing countries will be facing in the near future.

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. 

In this study, regional flood frequency relationships have been developed using L-moments for South Bihar, in the alluvial plains of Indo-Gangetic basin and Kaimur-Chhotanagpur Santhal Pargana plateau. The annual maximum peak flood data of twenty-two gauging sites whose catchment areas vary from 11.7 to 3171 sqkm have been used. The mean annual peak floods of these sites vary from 29.15 cumec to 1293.2 cumec. Comparative regional flood frequency analysis studies have been carried out using some of the commonly used frequency distributions viz Extreme Value (EV1), General Extreme Value (GEV), Normal, Log Pareto (GPA) and Wakeby based on L-moments approach.

The School of Environmental Studies - Jadavpur University (SOES-JU), has done path-breaking research in reporting and documenting the issue of Arsenic contamination in the country.
