Show moreRural, tropical coastal communities are experiencing sustained, often increasing food insecurity, poverty, and global change impacts. These challenges have stimulated a rise in projects aiming to enhance and diversify local livelihoods. The ability of these projects to achieve broad-scale benefits is limited by approaches that do not account for feedbacks among sectors and across marine and terrestrial environments. To address these limitations, we present an applied research agenda to support an integrated approach to livelihood project planning and management. This agenda explicitly examines interactions among natural resources, industries, and livelihoods and is based on three foundational activities: (1) a governance review and assessment, (2) strategic partnership formation, and (3) a diagnostic approach supported by science and shared outcomes. We add structure to the established logic in our field by broadening the sectoral and spatial scope of livelihoods projects, so they can better contribute to interrelated UN Sustainable Development Goals.

Show moreSystematic reviews, sometimes including meta-analyses, are often presented as an approach for identifying healthy and sustainable diets. Here we explore to which extent systematic review protocols have been adopted by studies comparing environmental impacts of foods based on Life Cycle Assessment (LCA) results, and to which extent they comply with the PRISMA protocol for transparent reporting. Out of 224 studies screened, seven explicitly define themselves as systematic reviews, and/or claim to carry out meta-analyses. Of these, only one acknowledges a review protocol, while none complies with all the PRISMA criteria. Neither do we believe that reviews of LCA results can comply with all the criteria or carry out meta-analyses, due to underreporting on standard deviations and artificial sample sizes in LCAs. Nonetheless, reviews of food commodities and diets based on LCA results would benefit from better aligning with criteria in systematic review protocols. Show less

Show moreChina is the world's largest producer, consumer, processor, and exporter of finfish and shellfish (defined here as "fish"), and its fish imports are steadily rising (1-3). China produces more than one-third of the global fish supply, largely from its ever-expanding aquaculture sector, as most of its domestic fisheries are overexploited (3-6). Aquaculture accounts for ∼72% of its reported domestic fish production, and China alone contributes >60% of global aquaculture volume and roughly half of global aquaculture value (1, 3). Show less
