UNESCO Publishes First World Map of Underground Transboundary Aquifers Posted on 02 Nov, 2008 11:29 AM

Forwarded to the Portal by: Anuradha The United Nations Educational, Scientific and Cultural Organization (UNESCO) will publish the first-ever world map of underground aquifers, which account for some 96 per cent of global freshwater resources, the agency announced in a press release today. Despite their strategic importance, no global inventory of aquifers , most of which straddle international boundaries , had been compiled before UNESCO started work on its online map, which will be launched to coincide with the submission to the General Assembly of a draft Convention on Transboundary Aquifers next week. The UNESCO is presenting a detailed map identifying underground water resources that are shared by at least two countries, using data compiled since 2000 by UNESCO's International Hydrological Programme for a groundwater database. The map will include information about the quality of water and rate of replenishment of the 273 transboundary aquifers , 68 in the American continent, 38 in Africa, 65 in Eastern Europe, 90 in Western Europe and 12 in Asia.

Microfinance for safe drinking water-ACCESS & HUL partnership
On the occassion of World Water Day 2008, ACCESS talks about its work in using microfinance to obtain safe drinking water. Posted on 21 Mar, 2008 12:12 AM

Drop by drop ACCESS & HUL in Base of Pyramid Partnership for Safe Drinking Water for Rural Poor:

Yakalakshmi lives in Nekkunda village, Telengana region in Andhra Pradesh with her husband and two children. Though she has water piped to her house by the village panchayat, her entire family fell ill for a month last monsoon season by drinking water directly from the tap. "We all got high fever and severe diarrhea", she says, "we had to spend around Rs. 4000 on health care, which was very difficult for us". So when she got the opportunity this January to buy an effective water purifier through her Self Help Group (SHG) on an installment basis she was one of the first to sign up. Yakalakshmi is just one of the beneficiaries of a unique tie-up between ACCESS Development Services, a microfinance technical services non-profit organization, and Hindustan Unilever Limited, one of the country's largest producers of fast-moving consumer goods, to provide safe drinking water to rural poor. "Most of these villages have piped water or boreholes", says Padma, Project Coordinator at a local NGO, PEACE, "the problem is that tests by UNICEF in this district show that up to 70 percent of these sources are contaminated."The contamination gets even worse during the rainy season, especially due to poor sanitation and waste-management practices.

Persian wheel : The water lifting device in Kolar, Karnataka
S.Vishwanath and Amitangshu Acharya document their visit to one of the last extant Persian wheels in the Kolar District of Karnataka Posted on 22 Jan, 2008 11:26 PM

img_0052.JPG What exactly is a Persian wheel? Also known as Rahat (in Urdu), it's a simple water lifting device, where a number of small pots are attached to a long chain. Two gear wheels make up the system and as the first one is revolved, the pots each dip and swallow water from the well and soon after pours itself out to a metallic shaft which in turns empties into an intricate network of troughs that distributes water adequately through the cropped area. It is believed that the technology originated in Egypt and as world shrunk through extensive trading, it spread to India and China.
