The monsoon has become active in the states of Tamil Nadu, Kerala, Lakshadweep and parts of coastal Andhra Pradesh. There are also reports of heavy rainfall in parts of Karnataka. At the same time, news from the north in the states of Himachal Pradesh and Kashmir includes reports of a cold wave and rains and the first snowfall of the season.

This report by the Kerala State Council for Science, Technology and Environment (KSCSTE) and Centre for Water Resources Development and Management (CWRDM) on water quality monitoring in Kerala covers all its forty four river basins. This is being done under the “Environmental Monitoring Programme on Water Quality” under which samples are being collected both from surface and groundwater sources.

Groundwater sampling stations were fixed after conducting a sanitary survey in the panchayats. Water Quality Information System is being developed using Geographical Information Systems (GIS) to manage the water quality from point or non-point source of pollution.

In the first phase of the project, three river basins of Kerala viz. Kabbini, Periyar and Neyyar were monitored. The network was later expanded to basins such as Chaliyar, Kadalundi, Meenachil, Karamana, Anjarakandi, Pamba, Muvattupuzha, Bharatapuzha, and Chalakudy. 

This paper published in the journal Environmental Health Perspectives briefly summarises the relevant literature and highlights the challenges and opportunities for innovative research in the context of the impact of changing temperatures and precipitation patterns due to climate change on the health of populations from developing countries such as India.

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.

This draft report on the study of lakes by the World Wildlife Fund for Nature (India) documents the physical condition of the lakes in Mumbai. Apart from the three lakes - Tulsi, Powai and Vihar that used to provide water to Mumbai residents, there are many lakes in the Bombay Municipal Corporation jurisdiction that are either polluted by human sewage or industrial effluents and have remained neglected with increasing urbanization.

There is very little to no data available on the existence of lakes of Mumbai. Several RTI’s to the government bodies also revealed that there was a lacuna in terms of the availability of the data; as a result most of the water bodies are easily exploited. Under this study the baseline data was prepared with the help of Google Earth website. The areas appearing to be lakes were marked on the Google Earth Images. These were verified by the field staff through onsite visits. The survey was conducted during September and October, 2008 and March, 2009. The study considers only the fresh water lakes which were accessible and saline water impoundments have not been considered.
