Land degradation reduces the ability of the land to perform many biophysical and chemical functions. The main aim of this study was to determine the status of land degradation in the study area using remote sensing and geographic information system.

The study of the hydrochemistry of the Manasbal lake was done to find out whether the lake water was fit for drinking, irrigation and other purposes.

The CGWB under the Ministry of Water Resources, Government of India, is the national apex agency entrusted with the responsibilities of providing scientific inputs for management, exploration, monitoring, assessment, augmentation and regulation of ground water resources of the country.

This document by the World Health Organisation, for the first time, sets forth global criteria to evaluate whether a household water treatment option reduces waterborne pathogens sufficiently to protect health. Through use of a risk-based framework and by emphasizing the philosophy of incremental improvement, it is intended to provide implementers and policy-makers with an evidence-based and pragmatic approach to select options suited to local conditions.

Household water treatment interventions may play an important role in protecting public health where existing water sources, including those delivered via a piped network or other improved sources, are untreated, are not treated properly or become contaminated during distribution or storage. Household water treatment applications are a range of technologies, devices or methods employed for the purposes of treating water at the household level or at the point of use in other settings, such as schools, health-care facilities and other community locations. Point-of-use water treatment is another term used for household water treatment.

It indicates that the aquatic ecosystem of an area disappeared due to unplanned development of agro ecosystems and human settlements. This area was earlier covered with ponds, wetlands and ox-bow lakes. Now, during the rainy season, inhabitants of these wards face severe problem of water logging and pollution. 

The various possible PPP structures for the sector were studied, and their applicability assessed in the context of the selected sample cities. Consultations led to development of term sheets for these PPP structures, which were identified as most suitable and feasible for implementation.

The above exercise has led to development of this report, which may be considered as a tool kit designed to help decision makers decide whether a particular project might be suitable for the PPP route or not. The tool kit can, therefore, be the basis for approving a project implementation structure as part of the overall project approval methodology.

The Level-I Laboratories are located at 258 field water quality monitoring stations on various rivers of India where physical parameters such as temperature, colour, odour, specific conductivity, total dissolved solids, pH and dissolved oxygen of river water are observed.

 The article dealt with the prediction of Indian summer monsoon rainfall by five atmospheric general circulation models (AGCMs) during 1985–2004.

Climate modeling studies indicate that there will be more spells of intense rainfall and frequent instances of extreme rainfall. This prediction is coming true, particularly in the central sector of the Himalayan belt, where there is pronounced decline in winter precipitation (both rain and snow) and prolonged spells of drought in summer broken by cloudbursts in localized areas.
