Migration plays a significant role in Gambian society, mainly in the form of remittances. Migrants typically do not move with their entire family, often leaving their spouses, children, and parents behind. The multiple adverse socioeconomic impacts of migration on "families left behind" have long been debated. The impact of migration on the families left behind is multifaceted and context-specific. Given the complexity of the causal relationship, there are limitations and gaps in the evidence base for the Gambia. Despite the data gap, as per various consultations with local level government authorities and internal IOM perception surveys, vulnerabilities of families left behind have been identified as a key challenge, particularly in the Upper River Region (URR) and Central River Region (CRR) of the Gambia, though the magnitude and the resulting impacts on family members is largely unknown. In light of the above, the objective of the project is to contribute to the Government of the Gambia's efforts to ensure protection for families left behind and further enhance their contribution to sustainable development. The project will seek to do so by supporting policymakers to use gender-sensitive evidence on the impact of migration on families left behind in the Gambia to further inform policies and interventions to respond to their basic socioeconomic needs (Outcome 1). This will be done by carrying out a comprehensive and gender-sensitive assessment, and an accompanying policy brief, on the impacts of migration on families left behind in the Gambia (Output 1.1); increasing the understanding of relevant state and non-state actors on women's and children's rights and the impact of migration on families left behind (Output 1.2); and developing a gender-sensitive National Plan of Action to mainstream protection concerns of families left behind in policies, development plans and programmes (Output 1.3).
