Against the discussion on the rationale and scope for water demand and supply management in India, this paper provides a brief overview of the status and effectiveness, as well as the technical, institutional and financial requirements of six demand management options (i.e. water pricing, water markets, water rights, energy regulations, water saving technologies, and user and community organizations) and one supply management option (involving the implementation of the National River Linking Project, NRLP). The paper then develops a framework that captures the analytics of water demand management in terms of both the impact pathways of and operational linkages among the options and their underlying institutions. Using this framework, the paper outlines a strategy for water demand management that can exploit well the inherent synergies among the options, and also align them well with the underlying institutional structure and its environment. Similarly, based on an analysis of the NRLP, the paper also indicates the strategy for implementing the NRLP and thereby promoting water supply management within the financial, institutional and political constraints. The paper concludes with the policy implications for water demand and supply management in India. Citation Saleth, R. M.

The present study investigates the temporal variability in monthly, seasonal and annual rainfall over a drought prone district in India. Long period rainfall data, from 1950 to 2012, were investigated over the district by analysis of anomalies and application of both parametric and non-parametric statistical tests. Decline in annual rainfall is evident in the study area with highest number of below mean rainfall years observed in the recent decade (2000–2009). Only 25% of the annual rainy days span across pre-monsoon, post-monsoon and winter season, reinforcing the high dependence of local communities on monsoonal rainfall for effective crop growth. Against this, a decreasing trend in monsoonal rainfall is noticed over the years. In conclusion, the present paper argues for district level rainfall studies which will provide local stakeholders with the necessary information for better planning and management of rainfall dependent development sectors, thus resulting in reduced overall socio-economic upheaval of rural communities.

India's climate is changing gradually from one year to another. A significant increase in surface air temperature in different Indian regions was observed from 1998 onwards, which became all the more pronounced in 2009. Monthly mean maximum and minimum temperatures were higher than normal values over the whole of India, accompanied by a sharp increase in the duration and frequency of hot days and heatwave conditions. In the light of these observations the paper is aimed at investigating the spatial and temporal variation of air temperature at different altitudes and the interannual trend for different months over the Indian region for a period of 108 years from 1901 to 2008. It is observed that the variation in air temperature is not uniform at all places in India. The yearly mean air temperature for the period 1948-2008 exhibits an increasing trend at all atmospheric layers from the surface up to 10 km. The recently observed increase in surface air temperature and longer periods of heatwaves and hot days in India may be due to a higher occurrence of dust storms and forest fires and the influence of local factors, such as a sharp population growth accompanied by uncontrolled urbanization and rapid industrialization, resulting in high levels of pollution and imbalances in the regional climate.

The paper surveys the energy problem in relation to global warming and the social criteria of India. India's failure to develop a policy on global warming is highlighted and her economic policy judged in relation to her energy options, including such notable work as jatropha development and nuclear energy.

This paper argues that the ability of women to adapt to climate change pressures will be enhanced by using the 'capabilities approach' to direct development efforts. By using this approach, women will improve their well-being, and act more readily as agents of change within their communities. This argument is supported by previous research on gender and livelihoods, and a study conducted in rural India. Examples are based on the experiences of poor, rural women in India, who are particularly vulnerable to climate change impacts. Their survival is dependent on their being able to obtain many essential resources from their immediate environment. Yet these women lack many of the requirements for well-being, such as access to healthcare, literacy, and control over their own lives. Gaining these would reduce their vulnerability to their changing environmental circumstances. [ABSTRACT FROM AUTHOR]
