Performance of endogenous adaptation measures to the flooding risk in the context of climate change in the urban municipality of Gueckédou in Guinea
Flooding is one of the oldest natural phenomena on the planet, causing damages. These damages most often affect the people, goods, services and activities of a community. Vulnerability and adaptation to the risk of urban flooding has become a concern, particularly in the African context, which is characterized by a great exposure to the consequences of this phenomenon. In the urban community of Gueckedou, flooding is caused by the overflow of the Waou and Boya rivers, which are the tributaries of the Makona River, 262 km long. It frequently leads to loss of life, housing, crops in the lowlands, agricultural production for food and trade, public health problems and periodic displacement of populations. The overall objective of the study is to improve the resilience of communities and resources to flood risks. This contribution assesses the performance of endogenous adaptation measures used to cope with flooding. The methodological framework is based on a combination of historical, participatory, geomatics and multi-criteria decision-aid (MCDA) approaches in a multi-stakeholder context. The participatory approach, in a multi-stakeholder context, allowed the involvement of several actors in the decision-making process. It promoted transparency and the consideration of the concerns of the various actors in the process of assessing endogenous adaptation measures with a view to strengthening the adaptation capacities of institutional actors and communities. The MCDA approach allowed to analyze the performance of the endogenous adaptation measures practiced by the communities, to identify the actors in the decision-making process, as well as the environmental, socio-cultural and economic issues. The criteria used were designed on the basis of expert opinion. These criteria were broken down into indicators to assess the most successful endogenous adaptation measures, in a participative and enriched decision-making framework. The evaluation matrix of endogenous adaptation measures is structured according to the actors, the endogenous adaptation measures themselves, and the issues that have been translated into criteria and indicators. It is analysed using the Visual PROMETHEE software. Four categories of measures have been identified: physical intervention measures, agricultural knowledge measures, early warning measures based on endogenous knowledge and social and territorial intervention measures for strengthening the adaptive capacity of local communities. In addition, the study shows the need for the participation of several actors, but also, sustainable and effective management of flood risks in an urban context. It illustrates the contribution of endogenous adaptation measures in public policies for disaster management and reduction in Africa, specifically in Guinea.
