This article by Sangeeta Deogawanka in the Geospatial World deals with the issues related to the use of geospatial technology for groundwater management in the country. Core agencies of the government dealing with the management and development of groundwater resources identify and map hotspots of salinity, chloride, fluoride, arsenic, iron and nitrate in groundwater. However, most online information is of a generic nature, lacking detailed database or methodology used. On the whole a picture evolves of national bodies looking into the groundwater policy and potential zoning on a hegemonic model, with regional state-level groundwater departments.

Water scarcity in Rajasthan as monsoons fail and Bilaspur- dam dries up

With the failure of monsoons in Rajasthan and dry-up of the Bilaspur dam, the water situation assumes graver proportions in most parts of Rajasthan, besides Jaipur, Tonk and adjacent districts. These areas, now in the news for acute water shortage problems, have always depended upon monsoons for their traditional rainwater-harvesting systems and the riverine sources.

While the Government has taken remedial measures with construction of tube-wells across the rural and drought-prone areas, they have been sporadic and insufficient at their best.  Merely announcing relief measures and planning of schemes on paper as an immediate disaster management strategy are not solutions to mitigation of water problems in this State.

Ponds are important sources of fresh water in the world as they store surface runoff produced by the storms. In this research paper, demarcation of the portion of land contributing runoff to ponds in village Nandgaon (Uttar Pradesh) has been done using topographical information of the surrounding area of the ponds, in a GIS interface.

The article is about the wetlands management issues that is surrounded by confusion and lack of proper water management policies, and how this can be tackled using GIS.

Guest post by Sangeeta Deogawanka

February 2nd, designated as World Wetlands Day, has quietly slipped by with isolated events that speak of the lackadaisical attitude towards this rich ecosystem.

With 67,429 wetlands covering an area of about 5.5 million hectares, [Ministry of Environment and Forests (MoEF), 1990], the wetland systems in India are diverse, found in high altitude cold zones, the hot and humid coastal areas or occurring as scattered inland wetland systems.

Information on the Flood Risk Mapping Study, funded by the Water Resources wing of the Public Works Department, an initiative of the Tamil Nadu State Government

For a GIS zealot like me, this is breaking news on the Indian mapping front. Finally a GIS application for risk-mapping and management of floods in India!

The Flood Risk Mapping Study, funded by the Water Resources wing of the Public Works Department to a tune of Rs 2,17 crores, is an initiative of the Tamil Nadu State Government. It is supported by the Centre's Department of Science and Technology and Survey of India in the research component of the project. This one-year project is being handled by Anna University’s Institute of Remote Sensing (IRS), Chennai.

An interesting read that draws the need to link climate change with rainfall

 Climate Change has already arrived in India.  The recent flooding in Andhra Pradesh and Karnataka is portentuous of the times to come.  As climate change accelerates, so will the unpredictability and intensity of the rainfall, giving rise to such anomalous situations asint the  flooding of  dry river basins in Southern India.
