Low carbon strategies for inclusive growth - An interim report of the Planning Commission's expert group
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. Posted on 28 Jun, 2011 11:44 PM

CoverSome 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.

Gravity based spring water supply systems in Vishakhapatnam: A sustainable solution to an age-old problem
The tribal inhabitants in water-rich Eastern Ghats mostly rely on the water reserves of natural springs and hill streams for their drinking water and other daily domestic needs. Posted on 23 Jun, 2011 05:42 PM

Gravity based spring water supply systems – A sustainable solution to an age-old problem With an annual rainfall of more than 1200 mm, this region has truly pristine and under-developed ground water resources. The water related issues are more complex in the hilly areas. Some of the most concerning issues that affect the current water scenario in the Eastern Ghats are pollution of water sources (springs & streams) leading to poor health, illiteracy and ignorance resulting in improper hygiene and sanitation practices. The burden on women and children is also high since they have to walk a long distance to the springs/streams for fetching water.

Accessing safe drinking water during floods in North Bihar
North Bihar has the distinction of having an additional season in a calendar year, clearly identified by the misery, destruction and fatality accompanying it. Posted on 13 Jun, 2011 03:23 PM

This season in the region is commonly referred to as – Barh (flood). For centuries local people have treated it as ‘a way of life’, and found ways to deal with it. Post independence, this ‘way of life’ gradually transformed into an assured annual devastation. The once self-sufficient communities in the flood plains have been relegated to being highly dependent on sources external to the village for their survival during floods.
