This website by the Yale University provides information on the global and countrywise ratings for environmental performance in the form of Environmental Performance Indices (EPI) for different countries. The site also provides details of EPI scores for India in comparison with the average scores globally.

This index was developed from the Pilot Environmental Performance Index, first published in 2002, and designed to supplement the environmental targets set forth in the U.N. Millennium Development Goals (http://en.wikipedia.org/wiki/Environmental_Performance_Index)

The author looks at three ancient Kannada and Sanskrit texts - Lokoparam, Manasollasa, Shivatattvaratnakara. All these texts were written between the 12th and 18th century. These texts record hydrological data ranging from cloud formation to traditional methods of preserving potable water.

This paper presents the status of lakes in Mysore. It gives emphasis to the Socio-Economic Natural Complex - Lake Ecosystems (SENCLE) model of lake preservation and management which includes socio-technical aspects of lake care.

This paper uses secondary data to showcase the water bodies that were built in the Vijayanagar Empire. The author states that there were 88 such water bodies and these were used for irrigation purposes and also for consumption.

The author gives a brief history of tank irrigation in South India. The number of irrigation tanks in India were 208,000, of which 120,000 were in the three Southern states of Andhra Pradesh, Karnataka and Tamil Nadu. These tanks irrigated 1.8 million hectares. The author uses graphs to point out to the decline in tank irrigation.

The basic objectives of this study were -
