The Treguine refugee camp in Eastern Chad, is in a semi-arid terrain of hard, crystalline rock, where hard-rock boreholes proved inadequate. Fortunately, a significant thickness of saturated sands and gravels in a nearby wadi provided a sufficient quantity of water, and tube wells were constructed using a vibro-bailing technique in a few hours.
The Application of Ecological Sanitation for Excreta Disposal in Disaster Relief Open Primary tabs configuration options Primary tabs
When responding to an emergency situation, ensuring safe excreta disposal is an urgent priority in the disaster relief effort. Depending on the environment, not all methods of sanitation are appropriate, so methods such as ecological sanitation (Ecosan) must be employed. Ecosan are sanitation methods and technologies that promote the safe resuse that allow additional benefits such as nutrient recovery, reforestation, and help begin post-disaster recovery and transition to sustainable develoment.
This article presents the experience of using the Community-Led Total Sanitation (CLTS) approach in a recent programme in Somalia and explains some of the adaptations that were necessary to adjust to the specifics of a fragile and insecure context. The article goes on to explore the applicability of CLTS in fragile and insecure contexts more generally, using examples from South Sudan, Chad, and Afghanistan, and argues that in some ways it is an ideal approach for overcoming some of the challenges of working in these areas.
Learning from water treatment and hygiene interventions in response to a hepatitis E outbreak in an open setting in Chad
In September 2016, Médecins Sans Frontières responded to a hepatitis E (HEV) outbreak in Chad by implementing water treatment and hygiene interventions. To evaluate the coverage and use of these interventions, we conducted a cross-sectional study in the community. Our results showed that 99% of households interviewed had received a hygiene kit from us, aimed at improving water handling practice and personal hygiene and almost all respondents had heard messages about preventing jaundice and handwashing.
