 The study attempted to understand the phenomenon of water contamination in the village by using GIS as a tool to locate and map water supply and sewage distribution systems in the village, in relation to human and animal dwellings, their wastes, sanitary practices and their connections with drinking water quality for a clearer understanding of the connections between these factors and possible

Atmospheric depressions sometimes initiate tropical cyclones in the pre- and post-monsoon season in the Bay of Bengal, which move to land and create havoc. Their intensity and pattern vary individually.

 It traces the historical growth of thinking on watershed in the region, and highlights issues and influences. Impacts and benefits are discussed in relation to sustainability. The review shows that success in these projects is usually isolated, mostly seen in small micro-watersheds with naturally good water harvesting conditions.

 Soil respiration is a major process affecting the global carbon cycle and nutrient flux in the terrestrial ecosystem. It is the major pathway for exchange of gases from soil to atmosphere, influencing atmospheric temperature and ultimately contributing to global warming.

 The area suffers from water scarcity, natural resource degradation, low crop productivity (1–1.5 t/ha), low rainwater use efficiency (35–45  per cent), high erosion, poor soil fertility, frequent droughts, poor irrigation facilities, heavy biotic pressure on forests, inadequate vegetation cover and frequent crop failure resulting in scarcity of food, fodder and fuel. The region has serious limitations of ground and surface-water availability and heavily depends upon perched water for drinking as well as irrigation.

 Himalaya is one of the youngest mountain systems on Earth, and has a direct influence on the climate, hydrology and environment of the Indian subcontinent. It is the abode of one of the world’s largest and mostly inaccessible area of glaciers outside the polar region and provides glacier-stored water to the major Indian river basins. Many of the Himalayan rivers are fed by snow and ice melt run-off from snow fields and glaciers.

 The agricultural ‘growth’ seen in the recent past in Gujarat is nothing but a good recovery from a major dip in production occurred during the drought years of 1999 and 2000, because of four consecutive years of successful monsoon and bulk water transfer through the Sardar Sarovar project. The real ‘miracle growth’ in Gujarat’s agriculture appears to have occurred during the period from 1988 to 1998.

This paper by Himanshu Thakkar published in the journal Development looks at the daunting challenges that future water demand places on India a

Abstract:

The goal is to reconstruct past system behavior and diagnose the causes of a major water crisis.  In order to do this, we develop a hydrologic-engineering-economic model to address the complexity of urban water supply arising from consumers’ dependence on multiple interconnected sources of water.
