Project summary
This project extends a previous study on flood risk assessment in N'Djamena, focusing on enhancing the evaluation of the social context of exposed populations. The study aims to understand the cascading effects on critical urban networks and services, including electricity, water supply, sanitation, transportation, and fuelwood supply. It also explores the integration of nature-based solutions and related urban developments to complement flood mitigation measures, thereby maximizing co-benefits for protecting goods and people from flood risks.
Tasks carried out by Ecoresil
Provision of general guidance and methodology for the project team, building upon the previous flood risk study in N'Djamena
Evaluation of socio-economic impacts of floods, including indirect costs and cascading effects through urban networks such as electricity, water, sanitation, transportation systems
Identification of socio-economic hotspots, guided their mapping, and evaluated economic benefits of interventions (avoided losses) for cost benefit and multicriteria analysis update
Contribution to the identification of the most suitable nature-based solutions (based on bottom-up assessment) to associate with flood mitigation components, to maximize co-benefits
Reprioritization of intervention areas and intervention variants leveraging the enhanced Power BI assessment tool
