Droughts and Floods

To what extent farmers and water resource managers already practice adaptive management and whether it is practiced in an optimal manner or could there be areas for improvement based on recent advancements in the theory of adaptive management are some of the questions that are particularly appropriate in the light of rapid changes in river basin water use and also in relation to basin closure.

This paper draws on the development and use of water resources in the Lower Bhavani Project (LBP), with the LBP reservoir and the 84,000 hectare (ha) LBP command area. The project diverts water from the Bhavani River, a tributary of the Cauvery River in Tamil Nadu.

This paper published in Current Science presents the results of the national project on ‘Seasonal Prediction of the Indian Monsoon’ (SPIM), which involved a comparison of the skill of the atmospheric models used in the country for prediction of the summer monsoon, in simulation of the year-to-year variation of the summer monsoon rainfall over the Indian region for 1985–2004.

The focus is concepts that capture the hybridity of irrigation systems as complex systems, and cross the boundaries of the natural and social sciences.

This standard operating procedure developed by the Department of Drinking Water and Sanitation includes all functions pertaining to disaster prevention, institutional mechanism, preparedness, early warning, relief, recovery and rehabilitation. It will apply to RWSS Department/ PHED/ PRED/ Sanitation Departments/ Board dealing with rural water supply and sanitation for natural disasters that the State is prone to. The standard operating procedure will not be applicable to nuclear, biological and chemical disasters.

Its aim aim was to improve the capacity of target communities to better manage in times of disaster. To set in motion a process that would sustain a short-term project, the Aga Khan Development Network drew on guiding principles developed from its experiences of projects in disaster reconstruction and more comprehensive development programs: high-quality community-based interventions, working on multiple fronts, and fostering linkages with strong institutional partners.

At the core of the project’s disaster management and mitigation strategy was the creation of empowered and highly motivated community-based organizations; their participation was critical in shaping and implementing initiatives that would best serve the needs of the vulnerable, particularly women and children.

The greater Himalayan region “the roof of the world” – contains the most extensive and rugged high altitude areas on Earth, and the largest areas covered by glaciers and permafrost outside the polar regions.

Recent scientific studies show that global warming is already causing environmental changes that will have significant global economic and social impacts. As the world's 4th largest emitter of greenhouse gases, India has to juggle the imperative demand for economic development with pressures for greater efficiency in the use of energy.

Climate change is a change in the statistical properties of the climate system when considered over long periods of time, regardless of cause. Climate change reflects a change in the energy balance of the climate system, i.e. changes the relative balance between incoming solar radiation and outgoing infrared radiation from Earth. The threat emanates from accumulated green house gas emissions in the atmosphere, generated through long term and intensive industrial growth and high consumption life styles of developed countries.

India and China account for one third of the world’s population; each consumes more freshwater than other nations. Per inhabitant per year, though, India uses less than half what’s used in the US, China uses less than one third. This YaleGlobal series examines India and China’s water use, their expectations for rising demand and recognition that shortages will disrupt economic progress.

The Planning Commission of India repeatedly warns that water will become a more serious issue than land or energy for India in years to come, points out Rohini Nilekani, in the second article of the series. India’s transition from an economy based on agriculture to a mixed one, with water use controlled by states rather than the federal constitution, already leads to conflicts. She urges planning for a low-water economy. Good governance and regulatory frameworks can prevent pollution and waste, while encouraging efficiency, reliable and fair allocation, and wise consumer choices.
