Tuvalu: state of emergency declared due to water shortages

The Pacific island nation of Tuvalu (pop. 10,544) has declared a state of emergency due to severe water shortages on 28 September 2011 after existing desalination plants broke, exacerbating an already dire situation. The Australian, New Zealand and U.S. Defence forces – together with the Red Cross – have set up emergency desalination plants on two of the country’s nine islands.

A Red Cross situation report said the former British colony relied mostly on rainwater, which had been scarce this year because of a La Nina weather pattern across the Pacific.

The government of Tuvalu said the water crisis was likely to last until at least January 2012, when there’s more chance of heavy rain.

Bangladesh: natural sediment may shield groundwater from arsenic

Contamination of deep groundwater with arsenic from shallower sources may not be as serious as feared — if pumping deep water is limited to domestic use, a study has found.

Exposure to arsenic-contaminated groundwater has been linked to almost one in every five deaths in Bangladesh, and some 100,000 deep wells have been constructed to pump deeper, cleaner water. Recent modelling studies have suggested that these cleaner water sources are also being contaminated — from shallower water seeping down to replenish deeper wells.

But a study published in Nature Geoscience [doi: 10.1038/ngeo1283] found that natural adsorption of arsenic by sediment — sand in the aquifers — reduces contamination risk in most areas.

The study was conducted as part of the Columbia University Superfund Research Program on the “Health Effects and Geochemistry of Arsenic and Manganese“.

Viet Nam: Integrating sanitation marketing into a national program

Nguyen, H.H. (2011). Integrating sanitation marketing into a national program : a case study in Vietnam. Brisbane, QLD, Australia, International Water Centre.

Supply-driven approaches to rural sanitation in Viet Nam, with associated toilet subsidies, have had little success over the last decade. Since 2003, International Development Enterprises (IDE) Vietnam has achieved better results in several pilots with an alternative approach involving rural sanitation marketing. As a result, the Danish International Development Agency (DANIDA) has supported IDE in collaboration with the Health Environment Agency of the Ministry of Health (MOH) (HEMA) to implement a rural sanitation marketing pilot project within the National Target Program II (NTP II) program in Quang Tri province since 2010. This report  provides an analysis of the potential as well as the constraints for integrating sanitation marketing into NTP II.
