    Aquaculture must develop within planetary boundaries. Experience from agriculture, such as in managing monocultures and using genetically modified crops, can inform sustainable solutions for aquaculture.

    Oil uptake during deep-frying of potato crisps can be modified by the presence of short amylose chains. The choice of cultivar and processing conditions that enhance levels of short amylose chains may facilitate the production of reduced-calorie crisps.

    Global geospatial datasets and a regression discontinuity design enable the country-level effects, such as agricultural policies, on crop yields and nitrogen pollution to be quantified. The influences of countries were much larger on nitrogen pollution than on crop yields.

    Fruit and vegetable supply in the United Kingdom has increasingly been characterized by reduced domestic production of fruit and vegetables and increased reliance on imports from climate-vulnerable countries. With increasing climate change, this may impact availability, price and consumption of fruit and vegetables in the UK, with health consequences, particularly for older people and low-income households.

    Traceability is key to food quality and safety, but its wider implementation is hindered by high costs and technical complexity. A newly proposed mobile-based bidirectional system based on information concatenation through products’ 2D barcodes offers an effective, cheaper and more flexible alternative.

    Understanding major sources of uncertainty in yield change facilitates adaptation strategies for cropping systems. Using eight crop models, 32 global climate models and two climate downscaling methods, it is shown that their relative contribution to uncertainty in climate–crop modelling depends on location.

    Evaluating food systems in a holistic way is paramount to their transformation. Recent initiatives show how true cost accounting can help achieve that transformation at policy, product, organizational, farm, and investment levels.

    The COVID-19 pandemic continues to impact health and livelihoods in West Africa. Exposure of food system fragilities by the pandemic presents the opportunity for regional-specific reforms to deliver healthy diets for all and promote resilience to future shocks.

    The multidimensional problems of food require integrated solutions. Yet, there is a lack of clarity on the operationalization of systems thinking in research. This is a major challenge for those working towards the Food Systems Summit.

    Effects of national policies on crop yield and nitrogen losses can be disentangled from environmental conditions using spatial discontinuities between international borders.

    Climate change increases the frequency and severity of drought in many agricultural regions. A novel big-data approach has been designed to shed light on the interactions between agronomic and environmental factors affecting the sensitivity of crop yields to drought.

    Food systems are driven by incentives that often lead to food being discarded before entering the market and to the degradation of natural resources. Vegetable production in the water-scarce province of Almería, Spain, illustrates this and highlights the need for policies ensuring ethical and environmental sustainability standards.
