The workshop on How to leverage the Illuminating Hidden Harvests approach for better small-scale fisheries data explored how the results and methodology of the study Illuminating Hidden Harvests: The contributions of small-scale fisheries to sustainable development study (IHH) can be leveraged to support the improvement of small-scale fisheries data, with a view to inform management and policy. [Author] The IHH is a global initiative of the Food and Agriculture Organization of the United Nations (FAO), Duke University and WorldFish carried out in support of the Voluntary Guidelines for Securing Sustainable Small-Scale Fisheries in the Context of Food Security and Poverty Eradication (SSF Guidelines). [Author] The IHH report, published in March 2023, provides new evidence about the benefits, interactions and impacts of small-scale fisheries to inform policy and practice. [Author] This workshop focused on sub-Saharan Africa as a starting point; however, in the future, collaboration and support could extend to other regions. [Author] The workshop concluded that there is considerable value in both the IHH approach and the data already collected that can be capitalized on, at both national and regional levels, taking country priorities into account. [Author] Small-scale fisheries organizations should be further empowered for engagement in relevant policy processes by equipping them with IHH data and information, and partnerships should be sought also outside the fisheries sector. [Author] Tailored communication pathways and products for diverse audiences will be needed, including multiple language translations and simplified versions of the IHH report. [Author] Using the IHH results and approach wisely will help improve the knowledge on the subsector and contribute to sustainable development. [Author]
