This report was developed under the Korean-funded “Sustainable Fish Value Chains for Small Island Developing States” project. [Author] The project aims to contribute to economic growth, job creation, and food and nutrition security. [Author] This publication summarizes a much more detailed report focusing on the semi-industrial value chains of mackerel scad and tuna-like species in Cabo Verde. [Author] It reveals that the artisanal and semi-industrial fleets represent 97 percent of total catches. [Author] The semi-industrial fleet is concentrated mainly on Santiago, São Vicente, and São Nicolau islands, with the associated value chains generating almost 9110 direct jobs. [Author] Most landings of the target species are processed into canned products, which in turn make up most exports especially to the European Union. [Author] The remainder, notably on other islands, supply the local market. [Author] The business environment is favourable, with ongoing improvements. [Author] The sustainability analysis contained in this publication assesses the economic performance, environmental impact, social aspects, and resilience to climate change. [Author] The report identifies strengths, weaknesses, opportunities, and threats and formulates a 10-year upgrading strategy to achieve environmental sustainability, and socioeconomic development through improved financing and investment opportunities, and enhanced economic performance of micro, small and medium-sized enterprises.
