  • Food production stability depends on yield, and planted and harvested areas, but most research has only studied yield response to climate. This study finds that planted area and harvestable fraction contribute substantially to US crop production shocks, emphasizing their key role in food system stability.

  • Understanding the propagation or attenuation of environmental variability and shocks along food supply chains is key to food security. This scoping review identifies entry points for variability, the main factors for variability diffusion, research gaps in terms of food items and types of shock studied, and risk reduction responses at individual, company and governmental levels.

  • A study proposes four ways in which foods sourced in aquatic environments can contribute to healthier, more environmentally sustainable and equitable food systems, and examines the relevance of these ambitions to nations.

  • Data on the nutrient content of almost 3,000 aquatic animal-source foods is combined with a food-systems model to show that an increase in aquatic-food production could reduce the inadequate intake of most nutrients.

  • A range of environmental stressors are estimated for farmed and wild capture blue foods, including bivalves, seaweed, crustaceans and finfish, with the potential to inform more sustainable diets.

  • This study presents the first annual update of the indicator framework developed by the Food Systems Countdown Initiative, published in Nature Food in 2023. Almost half of all indicators show some desirable trends. Governance and resilience indicators were revealed as the most connected across themes, constituting entry points for transformative change.

  • The nutritional, economic and livelihood contributions provided by aquatic food systems are threatened by climate change. Building climate resilience requires systemic interventions that reduce social vulnerabilities.

  • Global demand for “blue food” is growing. In this quantitative synthesis, the authors analyse global seafood demand and project trends to 2050, finding considerable regional variation in the relationship between wealth and consumption.

  • Data on aquatic food loss and waste are limited outside small-scale fisheries, and major gaps exist for aquaculture species that make up half of global production. This study estimates loss and waste in the US aquatic food supply chain from 2014 to 2018, including the top ten species groups that together represent 89% of the country’s aquatic food supply.

  • Global aquatic foods are a key source of nutrition, but how their production is influenced by anthropogenic environmental changes is not well known. The vulnerability of global blue food systems to main environmental stressors and the related spatial impacts across blue food nations are now quantified.

  • Aquaculture production systems in Bangladesh were configured to optimize the supply of micronutrients while minimizing environmental impacts. Increased production of small indigenous species enabled nutrient densities of farmed fish to match those of wild-caught fish, and systems that co-produce fish and rice had the lowest environmental burdens.

  • Producing sufficient food to support the planet’s growing population places enormous strain on critical ecosystems. Quantifying and mapping the individual and cumulative pressures from greenhouse gases, freshwater use, habitat disturbance and nutrient pollution provides crucial insight into producing lower-impact, more sustainable foods.

  • Achieving the Sustainable Development Goals requires examining the impacts of health interventions across multiple sectors and identifying regions where health–development–environment conflicts are most likely. Doing this is important for ending the epidemic of malaria by 2030 alongside achieving other SDGs.

  • Accurate and timely food production data are needed to promote food security and sustainability, but data scarcity exists across national and international levels. This Review examines data availability and reliability for crops, livestock and aquatic food production and recommends solutions to address data scarcity.

  • Australia is reforming its ineffective Environment Protection and Biodiversity Conservation Act, which currently allows the export of four threatened species listed under the Act along with additional species recognized as globally threatened. We propose three recommendations for the new legislation: (1) apply the same precautions to commercially harvested species as other threatened species; (2) mandate annual reviews of threatened species status; and (3) assess species listed on global conservation conventions.
