  • Global gridded crop models are increasingly used to assess climate change impacts on food production. Here, the authors assess crop yield uncertainty associated with soil data input, reporting that soil type strongly influences yield estimates, and may either buffer or amplify climate-related impacts.

  • Agriculture has a massive and growing footprint. This study finds that optimizing fertilizer and major crops globally could reduce by 50% needed global cropland, allowing restored vegetation on spared land to sequester carbon.

  • There are big uncertainties in the contribution of irrigation to crop yields. Here, the authors use Bayesian model averaging to combine statistical and process-based models and quantify the contribution of irrigation for wheat and maize yields, finding that irrigation alone cannot close yield gaps for a large fraction of global rainfed agriculture.

  • This work investigates changes in regularity of crop failure, heatwave and wildfire exposure for different future climate scenarios. Major shifts in dominant periods are observed when moving from pre-industrial to current climate conditions.

  • African rice production is facing high spatiotemporal variability in rice yields and uncertain supply chains. This study proposes a framework to assess the future impacts of socio-economic development and climate change on African rice availability and stability. Both local and trade-propagated climatic variabilities are important to identify future challenges.

  • Responses of agriculture and fisheries to climate change are interlinked, yet rarely studied together. Here, the authors analyse more than 3000 households from 5 tropical countries and forecast mid-century climate change impacts, finding that communities with higher fishery dependence and lower socioeconomic status communities face greater losses.

  • Climate change affects agricultural productivity. New systematic global agricultural yield projections of the major crops were conducted using ensembles of the latest generation of crop and climate models. Substantial shifts in global crop productivity due to climate change will occur within the next 20 years—several decades sooner than previous projections—highlighting the need for targeted food system adaptation and risk management in the coming decades.

  • Waterlogging threatens global crop production, yet it remains under-represented in agricultural impact assessments and crop models. This Review examines 21 crop models, identifying limitations in how they simulate waterlogging and coupled soil–crop processes. It also proposes pathways to enhance model accuracy for better agricultural adaptation and management.

  • Impact models projections are used in integrated assessments of climate change. Here the authors test systematically across many important systems, how well such impact models capture the impacts of extreme climate conditions.

  • Future agricultural productivity is threatened by high temperatures. Here, using 9 crop models, Schaubergeret al. find that yield losses due to temperatures >30 °C are captured by current models where yield losses by mild heat stress occur mainly due to water stress and can be buffered by irrigation.

  • The extent and cost of adapting agriculture to climate change depend on regional impacts and past adjustments, but uncertainties associated with a high-emissions scenario persist, according to simulations with a global land-use model based on multiple crop and climate projections.
