Gueladio Cissé: Vulnerability Assessment at Household and Community Levels for Adaptation to Climate Variability and Change in Secondary Cities in West Africa
The frequency of extreme weather events associated with climate variability and change, particularly floods, has increased in West Africa the last ten years. In the region riverine secondary cities, with the predominance of very simple traditional excreta disposal facilities (latrines) and traditional sources of water (like unprotected wells), the repeated occurrence of flooding events can negatively affect water quality and increase the burden of water related diseases.
Project general objectives
Reinforce by an ecohealth approach the communities capacities to adapt to processes of flooding in two climatic contexts (semi arid and tropical humid) of West Africa. Increase the adaptive capacities of the cities local governance actors and most vulnerable communities to climate change and climate variability impacts in particularly water and health sectors.
Study Framework - Methodology
Framework for adaptation to climate change
Evaluating the climate integrated risks and the adaptation challenges under three areas: (i)-hazards, (ii)-vulnerabilities, and (iii) adaptive capacity
Seasonal multidisciplinary surveys (geographical and household surveys) to assess risk factors and vulnerabilities in the face of flooding events at household and community levels.
The household surveys covered the entire targeted cities divided into three areas, following a three category stratified sampling scheme (200 households selected in each strata): (i)-areas most physically vulnerable to floods, zone1(ii) areas less physically vulnerable to floods, zone 2(iii) areas at an intermediary vulnerability level, zone 3
Zoning decided with local communities and partners
Wells, open wastewater and stagnant freshwater bodies in the streets, small cleaner surface waters, solid waste dumps, health centres, major holes, animals fences, green areas like urban agricultural fields, …
The project explores vulnerabilities and resilience of poor urban settlers in four secondary cities of West Africa, that are all located in close proximity to water bodies: (i) Korhogo, Côte d’Ivoire (212,000 inhabitants, near a dam); (ii) Kaédi, Mauritania (70,612 inhabitants, near a river); (iii) Ziguinchor, Senegal (269,000 inhabitants, near a river); and (iv) Kara, Togo (120,000 inhabitants, near a river).
Study Lead Message
The increasing occurrence of flooding events in a context of vulnerabilities at both household and community levels(predominance of very simple traditional excreta disposal facilities (latrines) and traditional sources of water (like unprotected wells), will threaten on water quality and consequently on health, and call upon appropriate adaptive management strategies of high interest for hundreds of similar secondary cities in Africa.
