My name is Deb Gangoapdhyay and I am a student at Yale University. I and a fellow student, Yuzhe Feng, have received funding to conduct a water quality and sanitation project in the Krisnanagar district of Nadia, West Bengal.
The following is a paper by Dr. Mohinder Slariya based on data collected during his Ph.D work. The work contains data sourced from the India Water Portal, and aims to illustrate local area climate changes with the development of hydroelectric projects. The abstract of the paper has been quoted below, with the full paper available as a download!
Dams have had serious impacts on the lives, livelihoods, cultures and spiritual existence of indigenous, tribal and illiterate people, moreover on the physical environmental conditions and on the biodiversity of the area concerned. The dam related developmental activities in Ravi catchment area have been threatening the biodiversity in the whole catchment. There are more than 50 rivulets in the Ravi catchment and on which more than 70 power projects have been planned by the government by putting biodiversity at the stake. Developmental activities have unintentionally produce weather and climate modifications on a larger scale and threaten the existing biodiversity. Such developmental activities have been started day back in 1980s in Ravi basin with the installation of Baira Suil Power Project and today it has covered all most all Ravi basin starting from interstate broader of Jammu & Kashmir, Punjab and Himachal Pradesh and engulfed the green cover of the area. Because of this extinction the catchments area is experiencing drastic climatic changes, because of 100 km reservoirs of Shahpur Kandi (125MW), Thein Dam (600MW), Chamera-I (540MW) and Chamera-II (300 MW) and tunnelization of Ravi in 19.38 kms with a dia of 7 to 9 meters and 102 meters high surge shafts with 15.5 meters dia and underground power houses of Chamera-I & II and dry Ravi in almost all its natural route (27 kilometers in Chamera I & II). In this dry region there is a tremendous increase in the temperature and there is no timely and usual rain in the basin after the installation of power projects.
Water and Sanitation Perspective series from Water Aid India, disseminates issues and experiences in India's water and sanitation sector. It is an outcome of WaterAid India's programme and policy work. It analyses the root causes for such a scarcity of water during the five year drought in Bundelkhand.
Here is a slightly long and complex paper but the sum and substance of it seems to be that Solar Disinfection (SODIS) combined with Nimbu pani is excellent to reduce e-coli count and inactivate it substantially. Nimbu paani also serves as an indicator that the water has been SODISED.
Attached is an interesting document from Prof. Prithvi Kandhal about using porous asphalt in parking lots so that rainwater seeps through it and recharges groundwater.
Dr. Kandhal has published many papers and has significant credentials in his areas of expertise. He resides in Jaipur after 35 years of working in the US.
