  • Cover cropping has been used in climate-smart agriculture due to benefits such as reductions in greenhouse gas emissions, but it can also have negative effects, such as decreased yields. Here the authors assess the various effects of cover crop adoption in the USA using data from over 100,000 fields.

  • Understanding recent trends in agricultural productivity and climate can inform mitigation and adaptation strategies. Based on satellite imagery, this study shows that yields have stagnated in much of southern Africa despite moderate climate trends over the past 20 years.

  • A key climate change adaptation goal in agriculture is to reduce drought sensitivity of crop yields. A comparison of two empirical strategies applied to US maize for detecting changes in drought sensitivity reveals the advantages of utilizing within-country spatial variability in drought exposure, driven primarily by differences in soil water-storage capacity.

  • Cropland area—and associated carbon dioxide emissions—in 110 studied countries is 6% higher than it would be without declines in agricultural productivity caused by climate change, according to a comparison of models with and without climate impacts.

  • The impacts of climate change on agriculture differ regionally and will increase hunger globally. Reducing tariffs and other barriers to international trade would mitigate this, but trade integration requires a careful approach to avoid reducing domestic food security in food-exporting regions.

  • Domestic strategies to increase carbon stocks in agricultural soils can lead to spillover effects in countries with less stringent policies. Thinking beyond domestic policy alone is needed for effective sustainable and climate-smart agriculture.

  • It is generally difficult to scale derived estimates and understand the accuracy across locations for passively-collected data sources, such as mobile phones and satellite imagery. Here the authors show that their trained deep learning models are able to explain 70% of the variation in ground-measured village wealth in held-out countries, outperforming previous benchmarks from high-resolution imagery with errors comparable to that of existing ground data.

  • An analysis of over 20,000 historical African maize trials suggests the crop will better cope with climate change under rain-fed management. For a 1 °C temperature rise, optimal rain-fed conditions would mean 65% of maize-growing areas in Africa would be likely to experience yield losses, compared with 100% under drought conditions.

  • Irrigation buffers crop yields from extreme weather, but comes at environmental costs. Here the authors show that in India irrigation has improved wheat yield and reduced its sensitivity to heat, yet further increases are unlikely to offset the impact of warming.

  • Expanding biofuel production into agricultural land reduces the need to clear natural ecosystems and can benefit the global climate through reduced greenhouse-gas emissions. A remote-sensing study of the Brazilian cerrado now provides empirical evidence that sugar-cane expansion also cools local climate directly by altering surface reflectivity and evapotranspiration.

  • Reducing agriculture’s impacts while increasing outputs is challenging. This study, of an Indian smallholder system, shows that microsatellite data can detect yield gains from a low-cost fertilizer intervention.

  • Statistical analysis of maize yields in the United States reveals a strong negative response to very high temperatures, and a relatively weak response to seasonal rainfall. Now simulations using a process-based model suggest that the most important effects of extreme heat are associated with increased vapour-pressure deficit—which contributes to water stress—rather than direct heat stress on reproductive organs.

  • One difficulty in anticipating the effects of climate change on agriculture is accounting for crop responses to extremely high temperatures. Now a remote-sensing study demonstrates accelerated ageing of wheat in northern India in response to extreme heat (>34 °C); an effect that reduces crop yields but is underestimated in most crop models.

  • On-farm adaptations could play an important role in moderating the adverse effects of climate change on agriculture. Here, a statistical approach is applied to assess the adaptation potential of agriculture in Europe, focusing on three major crops—maize, wheat and barley.

  • Agricultural productivity has increased historically, but the impact of climate change on productivity growth is not clear. In the last 60 years, anthropogenic climate change has reduced agricultural total factor production globally by 21%, with stronger impacts in warmer regions.

  • Feeding a growing population in a hotter world will require exploiting a far broader range of crop diversity than now — and that means valuing wild genes.

  • Climate and CO2 trends have driven significant changes in global crop water demand over the last 30 years but with variation by region and crop type. If trends continue, it could be a challenge for adaptation efforts to keep pace with water demand.
