This study investigates the impact of monthly Ganges–Brahmaputra river discharge variations on Bay of Bengal salinity and temperature during the period 1992–1999. The Ganges–Brahmaputra river discharge is characterized by a well-defined seasonal cycle with strong interannual variations. The highest/lowest yearly peak discharge occurs in summer 1998/summer 1992, with 1998 value amounting to twice that of 1992. This river discharge is then used to force an ocean general circulation model.

In late 2010 a group of professionals published a report of surveys conducted in the Sundarbans following the destruction caused by cyclone Aila in May 2009. This report shows how little we care to know about the people living in the delta. While the state government attempts to include it among the wonders of the world, the people living here are impoverished and vulnerable. The Sundarbans is a disasterprone region, but the government is yet to come up with a disaster management policy.

Accumulating evidence shows that the planet is warming as a response to human emissions of greenhouse gases. Strategies of adaptation to climate change will require quantitative projections of how altered regional patterns of temperature, precipitation and sea level could cascade to provoke local impacts such as modified water supplies, increasing risks of coastal flooding, and growing challenges to sustainability of native species.

Groundwater conditions in the multi-aquifer system in the Krishna River Delta, India, were studied through an integrated approach using hydrochemical, hydrogeological and isotopic techniques. This study

Water will be one of the critical drivers of peace and stability in South Asia in the second decade of the 21 century. If the first decade of the new millennium was shaped by terrorism, the next two decades (2010-2030) will witness issues around water dominating internal and external policies of countries, especially in

Until the 1940s, the irrigation and drinking water needs of India were met by rivers, ponds, lakes, dugwells, and rainwater sources. However, in the middle of the 20th century India continually faced two daunting challenges: providing food for an ever-growing population and decreasing the burden of highly prevalent water-borne diseases, including cholera, dysentery, and typhoid.

Land degradation, synonymous to desertification in arid, semi arid and sub-humid region, covers the processes adversely affecting productive capacity of land under different land use systems. Present paper reports the extent, type and severity of land degradation in south Asian countries.

Ecological diversity in Sunderban is at the threshold of decline. The fragile land here is being swallowed every day by gradual sea level rise, coastal erosion and tropical cyclones. Besides the global cause of sea level rise i.e. thermal expansion of sea water also responsible is the land degrading anthropogenic activity. An unsustainable situation has crept in the deltaic plain when natural capital is being used up faster than it can be replenished.

Stable isotope (? 18O and ? D) and salinity measurements were made on the surface waters collected from the Southern Indian Ocean during the
austral summer (25 January to 1 April 2006) onboard R/V Akademik Boris Petrov to study the relative dominance of various hydrological processes, viz. evaporation, precipitation, melting and freezing over different latitudes.
