An environmental evaluation of urine-diverting dry toilets in Hiloweyn Camp, Dollo Ado, Ethiopia.

Safe and hygienic management of human waste is essential in humanitarian settings. Urine-diverting dry toilets (UDDTs) can enable this management in some humanitarian emergency settings. A seeded, longitudinal environmental study was conducted in Hiloweyn refugee camp, Dollo Ado, Ethiopia, to measure Escherichia coli and Ascaris suum ova inactivation within closed UDDT vaults and to document environmental conditions (temperature, moisture content, and pH) that could influence inactivation.

Acceptability of urine diversion dry toilets in Dollo Ado refugee camp, Ethiopia.

Given the increasing frequency and duration of humanitarian emergencies worldwide, there is a need to identify a greater range of effective and contextually appropriate water, sanitation and hygiene (WASH) interventions. Typical sanitation systems may be poorly suited for some of the conditions in which humanitarian emergencies can occur, such as in drought-prone regions. Urine-diversion dry toilets (UDDTs) are one potential alternative sanitation option which can be used in these conditions.

Programmatic implications for promotion of handwashing behavior in an internally displaced persons camp in North Kivu, Democratic Republic of Congo.

Background: Diarrhea and acute respiratory infections (ARI) account for 30% of deaths among children displaced due to humanitarian emergencies. A wealth of evidence demonstrates that handwashing with soap prevents both diarrhea and ARI. While socially- and emotionally-driven factors are proven motivators to handwashing in non-emergency situations, little is known about determinants of handwashing behavior in emergency settings.

Water, sanitation and hygiene in Haiti: past, present, and future.

Haiti has the lowest rates of access to improved water and sanitation infrastructure in the western hemisphere. This situation was likely exacerbated by the earthquake in 2010 and also contributed to the rapid spread of the cholera epidemic that started later that same year. This report examines the history of the water, sanitation, and hygiene (WASH) sector in Haiti, considering some factors that have influenced WASH conditions in the country.

Access to safe water in rural Artibonite, Haiti 16 months after the onset of the cholera epidemic.

Haiti has the lowest improved water and sanitation coverage in the Western Hemisphere and is suffering from the largest cholera epidemic on record. In May of 2012, an assessment was conducted in rural areas of the Artibonite Department to describe the type and quality of water sources and determine knowledge, access, and use of household water treatment products to inform future programs. It was conducted after emergency response was scaled back but before longer-term water, sanitation, and hygiene activities were initiated.
