SSP was originally and primarily an irrigation and hydropower project. Today there is a shift in focus: one talks only of drinking water

New global models provide the opportunity to generate quantitative information about the world water situation. Here the WaterGAP 2 model is used to compute globally comprehensive estimates about water availability, water withdrawals, and other indicators on the river-basin scale.

During the last hundred years or so, deforestation and wind-water borne soil erosion have been steadily increasing and have now become the major environmental problems the world over.

The innovative use of stormwater drains to harvest water has meant a new lease of life for water starved Chennai

The evolution of groundwater quality at a wet zone in Sri Lanka was made clear using field investigation, chemical and isotopic analyses methods. In the wet zone, the concentrations of major ions and electrical conductivity (EC) in the groundwater are low with small seasonal change. Except for sodium, silica and chloride, the EC and other major ion concentrations increase along the groundwater flow direction. The contributions of bicarbonate and calcium ions to the increase in EC are the largest among the major ions.
