Achievements as of 2019: © UNEP Location: The Gambia Dates: 2017–2023 Ecosystem: Tropical forest, savanna, woodland and mangroves Large-scale Ecosystem-based Adaptation Context The Gambia is the smallest country in mainland Africa, extending over 400 km along the Gambia River in West Africa. One-third of the country lies below 10 m above sea level, and 10–20% of land is subject to seasonal or diurnal flooding, making the population of 2.1 million people highly vulnerable to climate change and rising sea levels. Climate projections suggest an increase in rainfall variability, and intense floods and droughts already cause crop failure in many areas. The agricultural sector provides two-thirds of household incomes, and many rural communities face a ‘hunger season’ from July to September. To provide alternative livelihoods and food sources, resources are unsustainably extracted from forest ecosystems, resulting in the degradation of ecosystem services, and further exacerbating crop failure. This project aimed to develop a sustainable natural resource-based economy in The Gambia, utilising nature and healthy ecosystems to reduce the impacts of climate change, through EbA. Project objectives: To restore degraded forests, savannas and farmland, and create healthy ecosystems. To establish ecologically sustainable businesses. To develop ‘home gardens’ to diversify food and income sources, and thus build climate resilience. To mainstream adaptation actions into policy to support large-scale implementation of EbA.
