Climate Change

This paper published in the journal Current Science presents the findings of a study has been taken up to quantify the possible impacts of the climate change on the water resources of Indian river systems within the constraints of the uncertainty of climate change predictions. The study uses the PRECIS daily weather data to determine the spatio-temporal water availability in the river systems.

A distributed hydrological model, namely SWAT has been used to simulate all the river basins of the country. The analysis has been performed to evaluate the severity of droughts and floods and thus identify the vulnerable hotspots that may require attention in view of the climate change in various parts of the country.

Impacts of climate change and climate variability on the water resources are likely to affect irrigated agriculture, installed power capacity, environmental flows in the dry season and higher flows during the wet season, thereby causing severe droughts and floods in urban and rural areas. Climate change impacts on water resources which are addressed and analysed in the present study include impacts on annual and inter-annual water availability as well as extreme events of droughts and floods.

These guidelines by the National Disaster Management Authority (NDMA) on management of landslides and snow avalanches aim to reduce the enormous destructive potential of landslides and minimize the consequential losses by institutionalizing the landslide hazard mitigation efforts. 

It is necessary that the hazard must first be recognized, the risk analyzed and an appropriate strategy developed at the national level to mitigate its impact. To achieve this objective, the NDMA initiated a series of consultations for drafting the national guidelines on landslides and snow avalanches to guide the activities envisaged for mitigating the risk emanating from landslides at all levels. The guidelines include regulatory and non-regulatory frameworks with defined time schedules for all activities. It is envisioned that all national and state disaster management plans and policies for landslides will be formulated and implemented keeping in view the overall framework of the guidelines.

This report by the Task Force, constituted by the Planning Commission, Government of India in April, 2008, is an outcome of the need expressed by the Prime Minister of India for a fresh analysis of the problems of the hill states and hill areas of the country in a manner that suggests that these areas do not suffer in any way on account of their peculiarities.

Opinions have been expressed that the pace of development of the Indian Himalayan Region (IHR) has been slow when compared to the rest of the country. At the same time, its fragile nature and difficulty of taking up conventional development initiatives has not been appreciated. In this report, arguments have been presented recommending reshaping of policies to bring in the “mountain perspective” for the IHR, in the national planning. Emphasis has also been laid on developing norms for good governance and for harnessing social capital at the grassroots.

The MoEF discussion paper on Himalayan glaciers studies the phenomenon of glaciations and glacier dynamics, a phenomenon that has attained significant attention in recent years, on account of the general belief that global warming and climate change is leading to fast degeneration of glaciers in the Himalayas. It is argued that this would, in the long run, have an adverse effect on the environment, climate and the water.

This article published in the Seminar 626, October 2011 argues that our current state of knowledge of water systems and ecological modelling related to flows of water, which includes projecting a single quantitative figure of water requirements, is inadequate. Such a unilateral prescription of environmental flows or water requirements of aquatic systems as a method for the resolution of water conflicts may actually become the source of many new conflicts.

These technologies include soil and water conservation measures, integrated farming, diversion based irrigation systems, sustainable agriculture, tree-based farming to name a few.
