In Solomon Islands, women's groups play an important role in promoting socially inclusive development and women's empowerment. In this paper, we summarise the experiences of a 5‐year participatory action research partnership to enhance rural livelihood activities based on aquatic foods. The women's savings groups that participated in this research identified solar‐powered freezers as an innovation suitable to their skills and environment. The 12 freezers we used in our partnership to pilot this innovation had tangible benefits. More than 700 unique users accessed the freezers, 3900 kg of fish was stored and over USD6,000 was saved in total; however, accumulation of savings varied greatly between groups. The women's groups demonstrated that operating solar‐powered freezers can be financially viable, and the innovation integrated well with their livelihood activities. This conclusion provides an alternative to dominant development narratives, which tend to focus on building large‐scale infrastructure, and often exclude women. Existing marketing skills and cooperation were strengths on which the women built. Poor‐quality technology was the biggest impediment to success. Solving this basic problem should be a priority for any future cold‐storage initiative. [ABSTRACT FROM AUTHOR]

Livelihood diversification is increasingly central to policy advice and investments in rural development and fisheries management. For small‐scale fishing communities in low‐ to middle‐income countries, more diverse livelihoods are generally hypothesized to reduce fishing pressure and vulnerabilities to external shocks and adverse trends while enabling people to construct routes out of poverty. Yet, evidence of impacts from livelihood diversification in small‐scale fisheries remains sparse. Our examination of the peer‐reviewed literature found substantial differences in how livelihood diversification is pursued, and in the realized outcomes from the process of diversification. Studies describing diversified livelihoods were almost as likely to report that livelihoods were not improved or that outcomes were mixed (54% combined) as they were to report improved livelihood outcomes (45%). Furthermore, one of the main theoretical drivers behind the support for diversified livelihoods—ecological conservation benefits—was unexplored in over 70% of studies. Of the minority of studies that did explore ecological outcomes, most reported that ecological conditions had not improved. These findings indicate conceptual ambiguity around livelihood diversification and a lack of empirical evidence supporting its theoretical underpinnings. There remain important questions about the impacts of diversification on multidimensional poverty and ecological conservation. Future research on and investment in diversification should be both more deliberate of what diversification means and more rigorous in the evaluation of its impacts. [ABSTRACT FROM AUTHOR]

Micronutrient deficiencies account for an estimated one million premature deaths annually, and for some nations can reduce gross domestic product1,2 by up to 11%, highlighting the need for food policies that focus on improving nutrition rather than simply increasing the volume of food produced3. People gain nutrients from a varied diet, although fish—which are a rich source of bioavailable micronutrients that are essential to human health4—are often overlooked. A lack of understanding of the nutrient composition of most fish5 and how nutrient yields vary among fisheries has hindered the policy shifts that are needed to effectively harness the potential of fisheries for food and nutrition security6. Here, using the concentration of 7 nutrients in more than 350 species of marine fish, we estimate how environmental and ecological traits predict nutrient content of marine finfish species. We use this predictive model to quantify the global spatial patterns of the concentrations of nutrients in marine fisheries and compare nutrient yields to the prevalence of micronutrient deficiencies in human populations. We find that species from tropical thermal regimes contain higher concentrations of calcium, iron and zinc; smaller species contain higher concentrations of calcium, iron and omega-3 fatty acids; and species from cold thermal regimes or those with a pelagic feeding pathway contain higher concentrations of omega-3 fatty acids. There is no relationship between nutrient concentrations and total fishery yield, highlighting that the nutrient quality of a fishery is determined by the species composition. For a number of countries in which nutrient intakes are inadequate, nutrients available in marine finfish catches exceed the dietary requirements for populations that live within 100 km of the coast, and a fraction of current landings could be particularly impactful for children under 5 years of age. Our analyses suggest that fish-based food strategies have the potential to substantially contribute to global food and nutrition security. Nutrient content analyses of marine finfish and current fisheries landings show that fish have the potential to substantially contribute to global food and nutrition security by alleviating micronutrient deficiencies in regions where they are prevalent.
