The Western Ghats Ecology Expert Panel (WGEEP) of the Ministry of Environment and Forests, Government of India (GOI) had been asked to identify ESAs along the Western Ghats, and to suggest how to manage them. The concept of ESAs has been extensively discussed in the literature. Several ESAs have been set up in India over the last 22 years under the Environment Protection Act, 1986, and a GOI committee under the chairmanship of Pranob Sen has proposed certain criteria for identification of ESAs.

This report by Aligarh Muslim University and Central Ground Water Board (CGWB) deals with groundwater flow modelling and aquifer vulnerability assessment in Yamuna–Krishni sub-basin of Muzaffarnagar district. For evaluation of the groundwater resources and for minimizing the error of estimation, the system has been evaluated through aquifer modelling where water balance is established using partial differential equation of groundwater flow and is solved with boundary and initial boundary conditions.

Tanks are rainwater harvesting techniques which capture water during monsoons for later use. Mention of tanks in colonial texts is made and the authors infer from ancient texts like Tamil Purananuru on the importance of tanks and the locations for their construction, as well detailing their geographical spread.

This paper presents the ancient water and soil conservation eco-systems of Sri Lanka, based on ancient texts and their modern interpretations, and highlights the use of these water systems  in ancient Sri Lanka and their present condition.

The state government's investments in supplying potable water under the Maharashtra Jeevan Pradhikaran (MJP) scheme which envisaged a no tanker supply' end to the scheme is critiqued.

High amounts of fluoride (>1.5 ppm) in drinking water is a serious issue in many parts of India. Fluorosis has been a serious issue in Andhra Pradesh, as early as 1999 with maximum reported levels at 29 ppm. Evidence indicates that 70-100% of the state is affected. 

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.

The authors study three tanks; one each in Karnataka, Andhra Pradesh and Kerala and find that almost all tanks in Southern India face similar problems that include farmers in command area being deprived of water, siltation, lack of proper maintenance of such structures, lack of political will to decentralise authority to tank institutions etc.
