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.

Thirsty earth: Indian villagers in Gujarat gather to draw water from a well

About 74 per cent of India's total population, currently about 1.25 billion, live in rural areas. More than one third of the water available to them is not potable. In a grim reminder that poor quality of drinking water leads to serious health problems, India has admitted that about 180,000 rural populated areas are afflicted by diseases which are caused due to impure, toxic organic and inorganic substances including tri-halo methane, chlorine, etc. Some states have reported multiple contaminations in drinking water and there is no doubt that the current water situation in India will get much, much worse unless suitable solutions are sought. Most existing purification methods not only remove the impurities but drain out the essential minerals as well. Moreover, they are expensive and require extensive maintenance. Thus a natural filter comprising of bamboo, gravel, pebble and other locally available natural adsorbents is a great alternative to carry out water purification. What makes this filter unique is the use of bamboo charcoal which is not commonly used in any filter designed for domestic purposes.

Celebrating the fact that per capita agricultural income is increasing faster than overall per capita income, the government is targeting 4% growth in agriculture in the Twelfth Plan period. But this is a rosy view that does not stand up to scrutiny.

 Dr. Y Venugopal Reddy begins by stating that the article offers a comprehensive, succinct and summary overview of the subject and is very useful as reference material. However, there is, a vital element that is missing in the analysis, namely, a discussion of the risks to the economy and economic agents. An enumeration and discussion of the many risks must be taken into account while framing the Twelfth Plan.

The year 2011-12 is the last year of the Eleventh Plan and this is therefore an appropriate time to review what has been achieved with a view to identify weaknesses in the strategy that need to be corrected, and also identify new challenges that may require new initiatives. The paper is presented in the hope of spurring a broader discussion on these issues.

Objective: To monitor and control from a single point the water quantity, quality, treatment and distribution process in real time for the entire city.

This project caters to the need for a real time water auditing, monitoring and control system for the entire city of Pimpri Chinchwad spread over 171 sq.kms with a water supply of 428 ML per day.
