Illuminating Hidden Harvests: The contribution of small-scale fisheries to sustainable development
by Food and Agriculture Organization (United Nations entity)
Small-scale fisheries are a vital source of livelihoods for millions, particularly in developing countries, and provide food and nutrition for billions. Despite this, SSF continue to be underreported and undervalued, causing them to receive little policy attention and investment at the national, regional and international levels. In response, FAO, WorldFish and Duke University are working in partnership with global experts to assess the contributions of small-scale fisheries. This effort is critical to supporting the growing momentum in implementing the Voluntary Guidelines for Securing Sustainable Small-scale Fisheries in the Context of Food Security and Poverty Eradication (SSF Guidelines), and action on the Sustainable Development Goals.

Encompassing the pre-harvesting, harvesting and post-harvesting sectors of inland and marine fisheries, the study asks the questions:

What are the social, environmental, economic and governance contributions of small-scale fisheries at global and local scales?
What are the key drivers of change in these sectors, including both threats and opportunities?

The research builds on the initial 2012 Hidden Harvest study by FAO, the World Bank and WorldFish, which highlighted the diverse and misreported livelihood and economic contributions of capture fisheries globally. The research found that small-scale fisheries in developing countries produce almost as much fish for direct domestic consumption as large-scale fisheries, and most of this is consumed locally in rural settings where poverty rates are high and quality nutrition is sorely needed. Importantly, the study highlighted that almost 50 percent of workers in the sector are women.

The new study will use a case study approach to engage with local expertise in priority countries that have substantial small-scale fisheries sectors or notable nutritional dependence on small-scale fisheries. The study will also take advantage of improved availability of relevant national and global datasets on fisheries, demographics, employment, fish consumption and nutrition in the synthesis and extrapolation process.

Besides updating many indicators from the first study, the new study seeks in particular to provide new synthesis on social and nutritional benefits, and social differentiation in the flow of benefits from different fishery sectors. A series of thematic studies will highlight available information on important themes that may include among others climate change impacts, contributions to conservation and governance, where global synthesis is perhaps not yet possible. The team will engage diverse expertise across the research sector to improve the depth of analysis, and the validity and precision of new estimates, as well as customizing reporting and information presentation for diverse end-user groups.

To maximize the reach and uptake of the research findings, the project will engage in ongoing and diverse communication activities.
