ABSTRACT

The fluorosis section of this website dedicated to Nalgonda district, highlights the acute problem of very high levels of fluoride in the ground water resources of the district and its impact on the health of people - a high prevalence of severe and crippling bone and skeletal deformities. The site has information on the status of the affected people, flouride levels and various articles, petitions and pictures.

The Total Sanitation Campaign (TSC) of the Rajiv Gandhi National Drinking Water Mission (RGNDWM), Govt of India was launched to cover all households with water and sanitation facilities and promote hygiene behaviour for overall improvement of health of the rural population. Panchayati Raj Institutions (PRIs) were involved in scaling up the TSC to promote large scale social mobilisation to bring about behavioural change.

This report by WHO and UNICEF, describes the global status and trends with respect to the use of safe drinking water and basic sanitation, and global progress made towards the Millennium Development Goals (MDGs) in the context of drinking water and sanitation targets. The findings reveal some striking disparities with respect to:

• the gap between progress in providing access to drinking water versus sanitation
• the divide between urban and rural populations in terms of the services
• the differences in the way different regions are performing
• disparities between different socio-economic strata in the society
• gendered differences in the burden experienced in accessing and collection of drinking water

The IEEE Spectrum magazine, the flagship publication of the IEEE, the world's largest professional technology association, recently brought out a special report on Water vs Energy. The report contains three main sections - Thirsty Machines (Water, Energy and Industry), Uneasy Harvest (Water, Energy and Agriculture) and Tiny Test Beds (potential solutions).

The Uneasy Harvest section contains a special report - "Pumping Punjab Dry", on the depleting groundwater situation in Punjab, and how cheap energy is endangering India's food security.

"Where Water meets Watts", is a map of Water and Energy hot spots and bright spots.

Groundwater models simulate groundwater flow in sub-surface aquifers in terms of quantity (level) and quality (such as salinity) using the mathematical or numerical approach. When a Groundwater model is embedded in a management framework these are often referred as managment models.

A widespread view that is gaining ground is that climate related migration could evolve into a global crisis by displacing a large number of people from their homes and forcing them to flee. Christian Aid postulates that a billion people could be permanently displaced by climate change related phenomenon such as droughts, floods and hurricanes (Christian Aid 2007). The fourth assessment report of the Intergovernmental Panel on Climate Change (IPCC) mentioned the “potential for population migration” due to increase in the number of areas affected by droughts and an increase in the intense tropical cyclones activities (IPCC 2007: 18). In particular, it seems likely that significant numbers of people will be displaced, either temporarily or permanently, from their homes as a consequence of global warming (Stern 2006). Available scientific evidences indicate that a large number of people might be displaced due to climate change. However, much of the literature on this issue refers to the question of whether the   people forced to migrate as a consequence of climate change should be described as climate refugees. There is no internationally agreed definition of the term “climate refugee” and the extent to which these displaced persons constitute a separate identifiable group. Although it is now widely recognised that climate change will significantly adversely affect India, there are few studies available on how climate change is going to affect the migration of people. It has been asserted that 70,000 people out of the 4.1 million living in the Indian part of the Sundarbans islands would be rendered homeless by 2020 (EPW, 6 June 2009).

This research report by the National Institute of Hydrology deals with optimum water management in a command area. The dynamics of water within the unsaturated zone of soil is a complex phenomenon dependent on properties of the atmosphere, soil and vegetation. For agriculture water management, it is necessary to have models that accurately predict the behavior of soil moisture.

In this study, a model is developed to stimulate the dynamics of soil moisture within the root zone in an agriculture command. Focus is given to incorporate the spatial variation in crop type, soil type and rainfall in the command area and the dynamics of soil-water-plant interaction is stimulated.

Rajiv  Gandhi  National Drinking Water Mission, Department  of  Drinking  Water  Supply,  Ministry  of  Rural  Development, Government   of   India,  funds  research  and  development  project proposals  from established  institutions  and universities. The project must be related to rural drinking water and sanitation. Please see below the priority areas identified by the Department in respect to research and development in sanitation.
