The agriculture sector in Sierra Leone accounts for 60 percent of GDP and 58 percent of total employment. More than 58 percent of the country’s population live in rural areas and 86.1 percent of this population are engaged in smallholder subsistence agricultural production. Ten years of civil conflict and the Ebola epidemic in 2014 negatively affected food security and the country’s overall socio-economic situation. The country is particularly vulnerable to extreme events such as food chain crises and natural hazards which have a direct impact on food security and livelihoods. This evaluation aims to identify lessons learned and provide strategic recommendations on how FAO programmes can be better oriented in Sierra Leone. FAO’s overall contribution to developmental challenges was assessed in the priority areas defined in the CPFs covering 2012–16 and 2017–19. The evaluation comprised an examination of associated outcome areas related to support to smallholder commercialization, natural resources management, and effective response to disasters and increasing social productivity and resilience. The review also evaluated crosscutting issues, including gender equality and women’s empowerment, climate resilience, nutrition, capacity development and youth employment.The evaluation used different methods to collect the views of the beneficiaries and other stakeholders, such as structured focus group discussions, structured key informant interviews, direct observation, and workshops. The fieldwork took place with actors from projects across five districts: Bo, Bombali, Kenema, Kono, and Port Loko.The evaluation found evidence of significant and sustainable results in a range of areas of FAO’s activities, including policy-related work, from adoption of legislation to policy influence, piloting of approaches, and standards and regulatory frameworks. Likewise, results leading to livelihoods improvements, empowerment and adoption of more sustainable organizational practices, technologies and skills were found. Nevertheless, the programme failed to aggregate activities and interventions in a programmatic and coherent portfolio. FAOs capacity to deliver sustainable and consistent results, with strong partnerships and complementary action, was often undermined by lack of, or weak systems and functions. FAO should use the development of the new CPF as a way to re-design its strategic footprint in the country and reach its full potential, despite the limiting factors. To do this, FAO could consider adopting an area-based approach, implementing a programmatic, multi-stakeholder and cross sectoral adaptive approach based on regions/districts.
