Groundwater

The presentation by ACWADAM deals with measurement of weather parameters and outlines the methods used in weather related data collection and analysis. Weather information is necessary for the planning and implementation of watershed programmes, especially in understanding factors like groundwater recharge, the relationship between recharge & discharge and in aspects like irrigation planning.

The presentation by ACWADAM deals with a case study of augmenting groundwater resources by artificial recharge in Kolwan valley, Mulshi taluka, Pune. The DfID funded project was undertaken by the British Geological Survey in collaboration with its partners in India from 2002–2005. The objectives of the study were:

• Improved knowledge of the impacts of managed aquifer recharge in different physical and socio-economic settings.
• Guidance on scope and effectiveness of managed aquifer recharge for implementers, funders and policy makers.
• Dissemination of knowledge.

The presentation by ACWADAM is part of the training module developed by them on “Planning, development and management of groundwater with special reference to watershed management programmes”. Pumping a well and observing the effect of such pumping on the water level in the pumped well as well as in the adjoining parts of the aquifer through observation wells is the basic procedure involved in a pumping test.

The paper by International Water Management Institute (IWMI), Challenge Programme for Water and Food (CPWF) and University of Arizona deals with energy supply and expansion of groundwater irrigation in the Indus-Ganges basin. Irrigation using groundwater has expanded rapidly in South Asia since the inception of the Green Revolution in the 1970s and it represents the largest source of irrigation in the basin.

The paper generated under the Challenge Program for Water and Food (CPWF) project explores in some depth a totally different dynamic in the irrigation economy of the vast Indo-Gangetic basin (IGB), an important exception to the global characterization. The global debate on ‘‘water as an economic good’’ presumes that irrigation water supply is delivered, controlled, and priced by public institutions. In the developing world, the price of water is kept so low that water use cost leaves farmers no incentive to use it efficiently. 

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. 

The legislation is likely to be in the form of an upgrade to the AP Water Land and Trees Act (WALTA).

The paper by the Institute for Social and Economic Change documents the case of Ward No. 39 situated at the outskirts of the Bangalore city to understand the emerging groundwater crisis due to overdraft in urban areas. Bangalore has no perennial river, which resulted in the growth of many lakes, acting as a source of groundwater recharge earlier.

This paper by the Institute of Social and Economic Change (ISEC) examines the extent of groundwater dependency and quality status in four South Indian cities viz., Hubli, Dharwad, Belgaum and Kolar cities. Widespread water shortage problems have resulted in increased dependency on groundwater with tapping the resources to unsustainable levels. In Karnataka, out of 208 urban local bodies that come under Karnataka Urban Water Supply and Drainage Board, 41 depend on groundwater.

The study by National Institute of Hydrology attempts to model seawater intrusion using FEFLOW, an interactive finite element simulation system in the coastal area of Bardez taluka in North Goa and evaluate the impact of increasing groundwater development on the phenomenon. Coastal tracts of Goa are rapidly being transformed into settlement areas and the poor water supply facilities have encouraged people to develop their own sources of water by digging or boring wells.
