Open AccessGlobal spatially explicit yield gap time trends reveal regions at risk of future crop yield stagnation
Yield gaps, here defined as the difference between actual and attainable yields, provide a framework for assessing opportunities to increase agricultural productivity. Previous global assessments, centred on a...

Open AccessGreenhouse gas emissions from US irrigation pum** and implications for climate-smart irrigation policy
Irrigation reduces crop vulnerability to drought and heat stress and thus is a promising climate change adaptation strategy. However, irrigation also produces greenhouse gas emissions through pump energy use. ...

Article
Open AccessEarthworms contribute significantly to global food production
Earthworms are critical soil ecosystem engineers that support plant growth in numerous ways; however, their contribution to global agricultural production has not been quantified. We estimate the impacts of ea...

Article
Sustainable irrigation and climate feedbacks
Agricultural irrigation induces greenhouse gas emissions directly from soils or indirectly through the use of energy or construction of dams and irrigation infrastructure, while climate change affects irrigati...

Article
Pathways framework identifies wildfire impacts on agriculture
Wildfires are a growing concern to society and the environment in many parts of the world. Within the United States, the land area burned by wildfires has steadily increased over the past 40 years. Agricultura...

Article
Irrigation in the Earth system
Irrigation accounts for ~70% of global freshwater withdrawals and ~90% of consumptive water use, driving myriad Earth system impacts. In this Review, we summarize how irrigation currently impacts key component...

Article
Warming reduces global agricultural production by decreasing crop** frequency and yields
Annual food caloric production is the product of caloric yield, crop** frequency (CF, number of production seasons per year) and cropland area. Existing studies have largely focused on crop yield, whereas ho...

Article
Snowmelt risk telecouplings for irrigated agriculture
Climate change is altering the timing and magnitude of snowmelt, which may either directly or indirectly via global trade affect agriculture and livelihoods dependent on snowmelt. Here, we integrate subannual ...

Article
The critical benefits of snowpack insulation and snowmelt for winter wheat productivity
How climate change will affect overwintering crops is largely unknown due to the complex and understudied interactions among temperature, rainfall and snowpack. Increases in average winter temperature should r...

Open AccessEstablishing long-term nitrogen response of global cereals to assess sustainable fertilizer rates
Insight into the response of cereal yields to nitrogen fertilizer is fundamental to improving nutrient management and policies to sustain economic crop benefits and food sufficiency with minimum nitrogen pollu...

Article
Open AccessCompetition for water induced by transnational land acquisitions for agriculture
The ongoing agrarian transition from smallholder farming to large-scale commercial agriculture promoted by transnational large-scale land acquisitions (LSLAs) often aims to increase crop yields through the exp...

Climate impacts and adaptation in US dairy systems 1981–2018
Animal-level responses to weather variability in US dairy systems are well described, but the potential of housing and other farm management practices (for example, fans and sprinklers) to moderate the impacts...

Article
Global map** of crop-specific emission factors highlights hotspots of nitrous oxide mitigation
Mitigating soil nitrous oxide (N2O) emissions is essential for staying below a 2 °C warming threshold. However, accurate assessments of mitigation potential are limited by uncertainty and variability in direct em...

Article
Quantification of global and national nitrogen budgets for crop production
Input–output estimates of nitrogen on cropland are essential for improving nitrogen management and better understanding the global nitrogen cycle. Here, we compare 13 nitrogen budget datasets covering 115 coun...

Open AccessGlobal irrigation contribution to wheat and maize yield
Irrigation is the largest sector of human water use and an important option for increasing crop production and reducing drought impacts. However, the potential for irrigation to contribute to global crop yield...
