Climate change and India - A sectoral and regional analysis for 2030s by the Indian Network for Climate Change Assessment (INCCA)
Assessment of impact of climate change on himalayas, western ghats, coastal areas and the north-east in 2030s Posted on 05 Dec, 2010 10:45 AM

This report prepared by the Indian Network for Climate Change Assessment (INCCA) provides an assessment of impact of climate change in 2030s on four key sectors of the Indian economy, namely agriculture, water, natural ecosystems & biodiversity and health in four climate sensitive regions of India, namely the Himalayan region, the Western Ghats, the Coastal Area and the North-East Region. This is the for the first time that such a comprehensive, long term assessment has been undertaken based on rigorous scientific analysis for the 2030s (all previous assessments were for the 2070s and beyond). 

Water security for India: The external dynamics - An IDSA Task Force Report
India to be 'water-stressed' by 2025 and 'water scarce' by 2050; what forces drive the demand and political dynamics? What are the hindrances & opportunities? Posted on 01 Dec, 2010 08:44 PM

The report by Institute for Defence Studies and Analyses is premised on the fact that India is facing a serious water resource problem and is expected to become 'water stressed' by 2025 and 'water scarce' by 2050. It raises fundamental questions about the forces driving water demand and the political dynamics of riparian relations, both in terms of hindrances and opportunities, amongst states in the subcontinent. Rivers, a crucial source of water resources, physically link upstream and downstream users and at the same time create barriers.

Palak Dil Lake - Mizoram
The beautiful lake of Palak Dil is unique amongst others for it is situated in the depression of a valley, it supportd life and living for many Posted on 26 Nov, 2010 03:00 PM

The Mizoram state has three types of (natural) lakes: valley lakes, tectonic/landslide lakes and artificial reservoirs, but the only lake of significance is Palak Dil, which is a natural lake in a depression in the hills. Palak Dil may possibly be a combination of valley and tectonic lakes. Locally in Mizoram, lakes are called dils. There are many such dils scattered all over the state, but they are tiny pools or marshy depressions such as Rengdil, Tamdil and Mampui Dil (Choudhury 2002). The Palak Lake is situated within the Mara Autonomous district Council, which is a region inhabited by the Mara Tribe. The Maras are distinct from the majority Mizos and in the Mara language the Palak Lake is referred to as Pala Tipa.

Water security vs national security published in Third Concept September 2010 : Countries that share a river face a higher probability of engaging in military disputes
Growing public and policy preoccupation worsens the impact on water security, especially with climate change impacts Posted on 28 Sep, 2010 10:15 AM

There has been growing public and policy preoccupation in recent years with potential climate impacts on water security in the wake of the worsening risk of global warming. In 1991, then–UN secretary general Boutros Boutros-Ghali pronounced that “the next war will be fought over water, not politics.” In 2001, Kofi Annan warned that “fierce competition for fresh water may well become a source of conflict and wars in the future.” And present UN secretary general Ban Ki-Moon has argued that the ongoing Darfur crisis grew at least in part from desertification, ecological degradation, and a scarcity of resources, foremost among them water. Apart from this chorus of concern, many policy scholars have asserted that, as population growth and economic development raise pressures on demand and environmental pressures degrade supplies, resource scarcities could precipitate violent international conflicts, with shared rivers an especially dangerous flashpoint.

Importance of groundwater – A presentation by ACWADAM
Used, overused and abused: understanding the importance of groundwater Posted on 22 Sep, 2010 08:03 PM

This presentation by ACWADAM deals with the importance of groundwater. It is well-known fact that groundwater forms a very crucial source of water supply in the national scenario on water resources today. And yet, it continues to remain a resource that is both abused and misused. Often, watershed projects suffer from insufficient inputs, especially hydrogeological to address the problem(s) of groundwater within the watersheds.
