  • HarvestStat

    Open AccessKeith F Davis, Weston Anderson et al.ARTICLEEnvironmental Research Letters2025

    Agricultural production statistics underpin diverse research efforts and development activities. Yet despite their critical importance, efforts to collate, update, and harmonize detailed sub-national agricultural production statistics are frequently redundant and incomplete due to the substantial time, effort, and resources required. The persisting lack of coordination and standards in the food systems data community wastes valuable resources and…

  • Regionalizing crop types to enhance global ecosystem modeling of maize production

    Open AccessYi Yang, Stephen M Ogle et al.ARTICLEEnvironmental Research Letters2021

    Improving the prediction of crop production is critical for strategy development associated with global food security, particularly as the climate continues to change. Process-based ecosystem models are increasingly used for simulating global agricultural production. However, such simulations often use a single crop variety in global assessments, implying that major crops are identical across all regions of the world. To address this limitation, …

  • Land use leverage points to reduce GHG emissions in U.S. agricultural supply chains

    Open AccessRylie E O Pelton, S Spawn et al.ARTICLEEnvironmental Research Letters2021

    Recognizing the substantial threats climate change poses to agricultural supply chains, companies around the world are committing to reducing greenhouse gas (GHG) emissions. Recent modeling advances have increased the transparency of meat and ethanol industry supply chains, where conventional production practices and associated environmental impacts have been characterized and linked to downstream points of demand. Yet, to date, information and e…

  • Climate change has likely already affected global food production

    Open AccessD K Ray, Paul West et al.ARTICLEPLoS ONE2019

    Crop yields are projected to decrease under future climate conditions, and recent research suggests that yields have already been impacted. However, current impacts on a diversity of crops subnationally and implications for food security remains unclear. Here, we constructed linear regression relationships using weather and reported crop data to assess the potential impact of observed climate change on the yields of the top ten global crops-barle…

  • The effects of climate extremes on global agricultural yields

    Open AccessElisabeth Vogel, Markus G Donat et al.ARTICLEEnvironmental Research Letters2019

    Climate extremes, such as droughts or heat waves, can lead to harvest failures and threaten the livelihoods of agricultural producers and the food security of communities worldwide. Improving our understanding of their impacts on crop yields is crucial to enhance the resilience of the global food system. This study analyses, to our knowledge for the first time, the impacts of climate extremes on yield anomalies of maize, soybeans, rice and spring…

  • Climate variation explains a third of global crop yield variability

    Open AccessD K Ray, James S Gerber et al.ARTICLENature Communications2015

    Many studies have examined the role of mean climate change in agriculture, but an understanding of the influence of inter-annual climate variations on crop yields in different regions remains elusive. We use detailed crop statistics time series for ~13,500 political units to examine how recent climate variability led to variations in maize, rice, wheat and soybean crop yields worldwide. While some areas show no significant influence of climate va…

  • Leverage points for improving global food security and the environment

    Open AccessPaul West, Paul C West et al.ARTICLEScience2014

    How to optimize global food production Keeping societies stable and managing Earth's resources sustainably depend on doing a good, steady job producing and distributing food. West et al. asked what combinations of crops and regions offer the best chance of progress. Their analysis focused on reducing greenhouse gas emissions, nutrient pollution, water use, and food waste. They identify regions that are likely to yield the best balance between app…

  • Yield Trends Are Insufficient to Double Global Crop Production by 2050

    Open AccessD K Ray, Nathaniel D Mueller et al.ARTICLEPLoS ONE2013

    Several studies have shown that global crop production needs to double by 2050 to meet the projected demands from rising population, diet shifts, and increasing biofuels consumption. Boosting crop yields to meet these rising demands, rather than clearing more land for agriculture has been highlighted as a preferred solution to meet this goal. However, we first need to understand how crop yields are changing globally, and whether we are on track t…

  • Increasing global crop harvest frequency

    Open AccessD K Ray, Jonathan A FoleyARTICLEEnvironmental Research Letters2013

    The world’s agricultural systems face the challenge of meeting the rising demands from population growth, changing dietary preferences, and expanding biofuel use. Previous studies have put forward strategies for meeting this growing demand by increasing global crop production, either expanding the area under cultivation or intensifying the crop yields of our existing agricultural lands. However, another possible means for increasing global crop p…

  • Recent patterns of crop yield growth and stagnation

  • Using Backcast Land-Use Change and Groundwater Travel-Time Models to Generate Land-Use Legacy Maps for Watershed Management

    Open AccessBryan Pijanowski, Bryan C Pijanowski et al.ARTICLEConservation Ecology2007Citada por: 1
