    Changements environnementaux et migration en Afrique de l’Ouest. Une revue des études de cas
    (2018)
    Piguet, Etienne 
    Cet article fait le point des connaissances existantes sur le lien entre changements environnementaux et migrations en Afrique de l’Ouest. Les aspects liés aux variations pluviométriques, aux augmentations de températures, aux sécheresses, à l’élévation du niveau des mers sont en particulier abordés. Quarante-trois études de cas sont présentées ce qui représente de manière quasi exhaustive l’état de la recherche sur le thème. En se concentrant uniquement sur cette sous-région et en présentant les lieux d’études, les méthodes utilisées, les concepts mobilisés et les principaux résultats obtenus, cette revue de littérature a l’avantage d’exposer une vue d’ensemble détaillée de la recherche au niveau méthodologique, conceptuel et géographique. Nous mettons en évidence dix acquis et enseignements majeurs émergeant de la littérature et qui caractérisent les migrations environnementales en Afrique de l’Ouest et les qualifions avec les métriques éprouvées de l’Intergovernmental Panel on Climate Change (IPCC). Finalement, nous avançons que d’un point de vue théorique, les travaux doivent s’orienter vers une vision compréhensive des migrations qui placent les dégradations environnementales dans leur contexte socioéconomique et politique. This paper reviews existing knowledge on the link between environmental changes and migration in West Africa. Aspects related to rainfall variations, temperature increases, droughts, and sea level rises are particularly addressed. Forty-three case studies are presented, which is almost an exhaustive representation of the state of research on the topic. By focusing only on this sub-region and presenting the places of study, the methods used, the concepts mobilized, and the main results obtained, this literature review has the advantage of presenting a detailed overview of the research at the methodological, conceptual and geographical level. We highlight ten major achievements and lessons emerging from the literature that characterize environmental migration in West Africa, qualified with the proven metrics of the Intergovernmental Panel on Climate Change (IPCC). Finally, we argue that from a theoretical point of view, work must be directed towards a comprehensive vision of migration that places environmental degradation in its socio-economic and political context.

    Migration and Climate Change: An Overview

    Climate change has become a major concern for the international community. Among its consequences, its impact on migration is the object of increasing attention from both policy-makers and researchers. Yet, knowledge in this field remains limited and fragmented. This article therefore provides an overview of the climate change – migration nexus: on the basis of available empirical findings, it investigates the key issues at stake, including the social and political context in which the topic emerged; States’ policy responses and the views of different institutional actors; critical perspectives on the actual relationship between the environment and (forced) migration; the concepts and notions most adequate to address this relationship; gender and human rights implications; as well as international law and policy orientations. Two major interconnected arguments arise. The first regards the weight of environmental and climatic factors in migration and their relationship to other push or pull factors, whether of a social, political, or economic nature. The second is about the political framework in which such migration flows should take place and the manner in which to treat the people who move in connection with environmental factors. The two issues are deeply intertwined, as the extent to which the environment determines migration is intimately connected to the status to be associated with the people concerned.
