  • Food systems and COVID-19

    The COVID-19 crisis has exacerbated weaknesses and tested resilience of food systems. This forward-looking Collection examines precarity of livelihoods and health in the wake of COVID-19 and considers some of the interventions needed to build food systems back better.

  • One health in aquaculture

    Aquaculture is one of the fastest growing and highly traded food sectors, and will become increasingly important in future food systems. This Collection highlights research and commentary on sustainable development of the aquaculture sector incorporating One Health principles - recognising the interconnected health and well-being of people, animals, plants and their shared environment.

  • Food systems and sustainable nutrition

    Large numbers of people are going hungry around the world and nutritional imbalances persist between low- and high-income nations. Not only are our food systems failing society but they are damaging the planet.

  • Sustainable, equitable and profitable Ocean economies

    The world is gearing up to grow ever more reliant on the ocean for food, energy provision and material resources. This collection - the result of a collaboration between the Ocean Panel and the Nature journals - examines the potential for sustainable, equitable and profitable growth in the ocean economy and what would it take to achieve this.

Nature Food is a Transformative Journal; authors can publish using the traditional publishing route OR via immediate gold Open Access.

  • 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.

  • The quantification of greenhouse gas emissions related to food production and consumption is still largely hindered by the availability of spatial data consistent across sectors. This study provides a detailed account of emissions from land-use change, farmland, livestock and activities beyond the farm gate associated with plant- and animal-based foods/diets—culminating in local-, country- and global-level emissions from each major agricultural commodity.

  • Increasing nitrogen use efficiency is the most effective strategy to reduce undernourishment while respecting the nitrogen boundaries in regions such as China and India. This supply-side effort plays a more important role in alleviating food insecurity than demand-side efforts such as diet shifts and reduced waste when introducing regional nitrogen targets.

  • Biodiversity in food systems is key to ensuring healthier diets, more sustainable food production and increased resilience to environmental and socio-economic disturbances. On the basis of a comprehensive scoring framework, the Agrobiodiversity Index proposed in this study gives a clear picture of agrobiodiversity at the country level as well as guidance to enhance it.

  • Higher income is associated with healthier, but more environmentally detrimental, diets in the United States. Healthy diets with lower environmental impacts are achievable within current food budgets for the majority of the population, but are unaffordable for 38% of Black and Hispanic people in the lowest income and education groups.

    • The continued proliferation of certification schemes aimed at mitigating social and environmental problems in the food sector calls for constant stocktaking of their effects. This Review examines some of the most prominent sustainability standards to discuss the issues of causality, exclusion, compliance and monitoring, excess supply and emerging country markets—ultimately identifying directions for future research.

    • Labour exploitation in the agrifood sector must be addressed for sustainability. Data-driven methodologies can identify risk hotspots and facilitate development of mitigation strategies.

    • US–China trade relations have implications for global nitrogen and phosphorus surpluses, and increasing blue water demand. The case shows that trade policy analysis needs to integrate environmental considerations.

    • China’s potato policy, introduced to improve food security, shows that substituting staples with alternative crops, though rarely the focus of dietary advice for planetary health, can also reduce the environmental impacts of food.

    • Natural biomass cycling and avoidance of biomass overharvest are the basis of a sustainable food system. This study proposes five guiding principles for biomass use based on the concepts of ecology and circularity, as well as leverage points for their implementation.
