This presentation  highlights the grave water situation in Bihar in the context of the emerging water quality and quantity issues that the world and especially developing countries will be facing in the near future. Read More

This Interim Report of the Expert Group of Planning Commission on Low Carbon Strategies for Inclusive Growth provides a menu of options that can reduce India’s emission intensity over the time frame. Some policy measures implied by various options have also been indicated. The main sectors examined in the report are power, transport, industry, buildings and forestry.

Increased concentrations of Green House Gases (GHGs) and the overall warming of the atmosphere has resulted in changing rainfall patterns, disruption in hydrological cycles, melting of ice caps and glaciers, rise in sea levels, and increase in frequency and intensity of extreme events such as heavy precipitation and cyclonic activities.

These have in turn had serious impact on sustainability of water resources, agriculture, forests and ecosystems, affecting the well being of billions of people on earth. Widespread melting of glaciers and snow cover will reduce melt water from major mountain ranges (e.g. Hindu Kush, Himalaya, Andes) where more than one billion people currently live.

This paper in Current Science reports the role of remote sensing and geographical information system in the identification of geomorphic records and understanding of the local controls on the retreat of glaciers of the Baspa valley in Himachal Pradesh. The geomorphic records mapped are accumulation zone, exposed ablation zone, moraine-covered ablation zone, snout, deglaciated valley, lateral moraine, medial moraine, terminal moraine and hanging glacier.

This paper in Current Science deals with the recession and reconstruction of Milam glacier in Kumaon Himalaya. 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.
