CIGAR Consortium.png.jpeg CIGAR Consortium (Water Security) Last Updated on 2012-07-09 12:25:24 The CGIAR Consortium is a global partnership that unites organizations engaged in research for a food secure future. CGIAR Consortium The name CGIAR comes from the acronym for the Consultative Group on International Agricultural Research. In 2008 the CGIAR underwent a major transformation. To reflect this and yet retain our roots we have kept CGIAR as our name. CGIAR research is dedicated to reducing rural poverty, increasing food security, improving human healthand nutrition, and ensuring more sustainable management of natural resources. It is carried out by 15 Centers, thatare members of the CGIAR Consortium, in close collaboration with hundreds of partner organizations, including national and regional research institutes, civil society organizations, academia, and the private sector. The 15 Research Centers generate and disseminate knowledge,... More »
Tuvalu Funafuti WikimediaCommons.jpg Tuvalu (Water Security) Last Updated on 2011-10-04 00:00:00 Tuvalu is an island group and nation of under 11,000 people, consisting of a densely populated, scattered group of nine coral atolls with poor soil in the South Pacific Ocean, about one-half of the way from Hawaii to Australia. Tuvalu is one of the smallest and most remote countries on Earth. Six of the nine coral atolls - Nanumea, Nui, Vaitupu, Nukufetau, Funafuti, and Nukulaelae - have lagoons open to the ocean; Nanumaya and Niutao have landlocked lagoons; Niulakita does not have a lagoon. Since there are no streams or rivers and groundwater is not potable, most water needs must be met by catchment systems with storage facilities (the Japanese Government has built one desalination plant and plans to build one other). Tuvalu is concerned about global increases in greenhouse gas emissions and their effect on rising sea levels, which threaten the country's... More »
Tokelau-NukunonuLagoon CIA.jpg Tokelau (Water Security) Last Updated on 2011-10-04 00:00:00 Tokelau is group of three low-lying coral atolls (Atafu, Fakaofo, Nukunonu) enclosing large lagoons in the South Pacific Ocean, about one-half of the way from Hawaii to New Zealand. The lagoons are surrounded by a number of reef-bound islets of varying length and rising to over 3 m above sea level. A self-administering territory of New Zealand, Tokelau is home to nearly 1,400 people. Its major environmental issues include limited natural resources and overcrowding which are contributing to emigration to New Zealand. Tokelau lies in Pacific typhoon belt. Originally settled by Polynesian emigrants from surrounding island groups, the Tokelau Islands were made a British protectorate in 1889. They were transferred to New Zealand administration in 1925. Tokelau and New Zealand have agreed to a draft constitution as Tokelau... More »
Drought-Livestock-Somalia 490px FEWS-NET.jpg Drought in Eastern Africa Last Updated on 2011-01-29 00:00:00 More Frequent Drought Likely in Eastern Africa The increased frequency of drought observed in eastern Africa over the last 20 years is likely to continue as long as global temperatures continue to rise, according to research published in Climate Dynamics. This poses increased risk to the estimated 17.5 million people in the Greater Horn of Africa who currently face potential food shortages. Scientists from the U.S. Geological Survey and the University of California, Santa Barbara, determined that warming of the Indian Ocean, which causes decreased rainfall in eastern Africa, is linked to global warming. These new projections of continued drought contradict previous scenarios by the Intergovernmental Panel on Climate Change predicting increased rainfall in eastern Africa. This new research supports efforts by the USGS and the U.S. Agency for International Development... More »
WaterDrop Splash 350px Flickr eyesore9.jpg What Were They Drinking? Last Updated on 2011-01-23 00:00:00 What Were They Drinking? Researchers Investigate Radioactive Crock Pots Radioactive toothpaste, suppositories, makeup: Would-be inventors seeking to capitalize on the discovery of radioactivity in the late 19th century produced a plethora of questionable medical devices and treatments. Among the most famous of these was the Revigator, an earthenware vessel that, according to an advertisement, would infuse drinking water with “the lost element of original freshness—radioactivity. With some technical assistance from the National Institute of Standards and Technology (NIST), researcher Michael Epstein and a group of students* at Mount Saint Mary’s University in Emmitsburg, Md., discovered that the risk the Revigator posed flowed not so much from the radioactivity, but from the presence of toxic elements dissolved in the water. The Radium Ore Revigator... More »
