Article Synopsis
  • A healthy ocean significantly contributes to human well-being by providing essential resources like medicines, food, and recreational opportunities, but its benefits are often overlooked.
  • Climate change, pollution, loss of biodiversity, and social inequities pose serious threats to both ocean health and human health.
  • To harness the ocean's health benefits sustainably, there must be a focus on equitable partnerships, enforcement of laws, and attention to human rights, social justice, and sustainability, with the healthcare sector playing a key role in this initiative.

Nearly a billion people depend on tropical seascapes. The need to ensure sustainable use of these vital areas is recognised, as one of 17 policy commitments made by world leaders, in Sustainable Development Goal (SDG) 14 ('Life below Water') of the United Nations. SDG 14 seeks to secure marine sustainability by 2030.

Wild-caught fish provide an irreplaceable source of essential nutrients in food-insecure places. Fishers catch thousands of species, yet the diversity of aquatic foods is often categorized homogeneously as 'fish', obscuring an understanding of which species supply affordable, nutritious and abundant food. Here, we use catch, economic and nutrient data on 2,348 species to identify the most affordable and nutritious fish in 39 low- and middle-income countries.

Article Synopsis
  • Injustices in food systems lead to a situation where a small number of individuals accumulate great wealth while around one in ten people experience hunger across 194 countries.
  • Research using Bayesian models highlights that economic and political barriers limit both wealth and food production, with a lack of education and accountability contributing to these disparities.
  • The analysis of policy documents shows a consistent neglect of political and gender inequalities, although effective policies promoting equitable food systems emphasize human rights, inclusive decision-making, and challenge systemic injustices.

Poverty and food insecurity persist in sub-Saharan Africa. We conducted a secondary analysis of nationally representative data from three sub-Saharan Africa countries (Malawi, Tanzania, and Uganda) to investigate how both proximity to and engagement with small-scale fisheries are associated with household poverty and food insecurity. Results from the analysis suggest that households engaged in small-scale fisheries were 9 percentage points less likely to be poor than households engaged only in agriculture.

Small-scale fisheries account for 90% of global fishers and 40% of the global catch. Effectively managing small-scale fisheries is, therefore, crucial to progressing the United Nations Sustainable Development Goals (SDGs). Co-management and community-based fisheries management are widely considered the most appropriate forms of governance for many small-scale fisheries.

Article Synopsis
  • Fish are crucial for providing essential nutrients and fatty acids, helping to reduce dietary deficiencies globally.
  • Research indicates that foreign fishing activities contribute more nutrients to nutrient-secure countries compared to international fish trade, with both practices benefiting these nations disproportionately.
  • To effectively tackle nutrient deficiencies, it's essential to prioritize nutritional goals in fisheries licensing and trade discussions, especially considering the vulnerabilities of certain nations due to climate change impacts.

To build capacity for addressing complex sustainable development challenges, governments, development agencies, and non-governmental organizations are making substantial investments in governance networks. Yet, enthusiasm for establishing governance networks is not always matched by empirical evidence on their effectiveness. This gap challenges these groups to know whether investing in governance networks is worth their time and effort; a weighing-up that is particularly critical in contexts of limited resources.

One of the most pressing challenges facing food systems in Africa is ensuring availability of a healthy and sustainable diet to 2.4 billion people by 2050. The continent has struggled with development challenges, particularly chronic food insecurity and pervasive poverty.

Small-scale fisheries and aquaculture (SSFA) provide livelihoods for over 100 million people and sustenance for ~1 billion people, particularly in the Global South. Aquatic foods are distributed through diverse supply chains, with the potential to be highly adaptable to stresses and shocks, but face a growing range of threats and adaptive challenges. Contemporary governance assumes homogeneity in SSFA despite the diverse nature of this sector.

Effective actions for the fishery and aquaculture sectors to contribute toward improving nutrition rely on an understanding of the factors influencing fish intake, particularly amongst vulnerable populations. This scoping review synthesises evidence from 33 studies in the African Great Lakes Region to examine the influence of food environments on fish acquisition and consumption. We identified only two studies that explicitly applied a food environment framework and none that linked policy conditions with the contribution of fish to diets.

Article Synopsis
  • * Fish are a vital source of essential nutrients but are often overlooked; understanding their nutrient composition could help address food and nutrition security issues.
  • * The study reveals that specific environmental conditions and fish species characteristics influence nutrient levels, indicating that enhancing fish-based food strategies could greatly benefit populations with inadequate nutrient intake, particularly children.

This synthesis article joins the authors of the special issue "Gender perspectives in resilience, vulnerability and adaptation to global environmental change" in a common reflective dialogue about the main contributions of their papers. In sum, here we reflect on links between gender and feminist approaches to research in adaptation and resilience in global environmental change (GEC). The main theoretical contributions of this special issue are threefold: emphasizing the relevance of power relations in feminist political ecology, bringing the livelihood and intersectionality approaches into GEC, and linking resilience theories and critical feminist research.

Article Synopsis
  • Development policy is shifting towards enhancing capacities for adaptation and innovation, but there's a lack of focus on how social and gender differences affect these capacities.
  • A qualitative study in the Solomon Islands shows that elements like assets, flexibility, learning, social organization, and agency are interconnected, impacting the ability to adapt and innovate.
  • Results indicate that women and youth face barriers like limited education and mobility, which hinder their ability to connect with external support, while risk-taking and challenging social norms affect innovative capacities for both genders differently.

Periodically-harvested closures are commonly employed within co-management frameworks to help manage small-scale, multi-species fisheries in the Indo-Pacific. Despite their widespread use, the benefits of periodic harvesting strategies for multi-species fisheries have, to date, been largely untested. We examine catch and effort data from four periodically-harvested reef areas and 55 continuously-fished reefs in Solomon Islands.
