A scalable satellite-based crop yield mapper
July 2015
A new approach to mapping crop yields is presented.Estimates are made within Google's Earth Engine, allowing broad scale application.Field-level estimates are tested against over 29,000 ground...
Climate Change Impact on Agriculture: Implications for Food Security and Hunger
June 2015
David Lobell’s recent research indicates that negative impacts to the global agriculture system are much more likely, more severe and wider-ranging in the face of human-caused climate change....
Incorporating Climate Uncertainty into Estimates of Climate Change Impacts
May 2015
Quantitative estimates of the impacts of climate change on economic outcomes are important for public policy.
The effects of extremely wet planting conditions on maize and soybean yields
February 2015
Short durations of very high spring soil moisture can influence crop yields in many ways, including delaying planting and damaging young crops.
The Evolving Sphere of Food Security
September 2014
The Evolving Sphere of Food Security seeks to answer two important questions: How do the priorities and challenges of achieving food security change over time as countries develop economically?
Getting caught with our plants down: the risks of a global crop yield slowdown from climate trends in the next two decades
July 2014
In many discussions of climate change impacts in agriculture, the large magnitudes of expected impacts toward the end of the century are used to emphasize that most of the risks are to future...
Climate Engineering Reconsidered
June 2014
Stratospheric injection of sulphate aerosols has been advocated as an emergency geoengineering measure to tackle dangerous climate change, or as a stop-gap until atmospheric carbon dioxide levels...
Climate change adaptation in crop production: Beware of illusions
June 2014
• Adaptation should be defined strictly as actions that reduce climate change impacts.• Many studies that claim to show adaptation benefits do not satisfy this definition.• Three main causes of ...
Adaptation potential of European agriculture in response to climate change
May 2014
Projecting the impacts of climate change on agriculture requires knowing or assuming how farmers will adapt.
Greater sensitivity to drought accompanies maize yield increase in the US Midwest
May 2014
A key question for climate change adaptation is whether existing cropping systems can become less sensitive to climate variations.
A meta-analysis of crop yield under climate change and adaptation
March 2014
Feeding a growing global population in a changing climate presents a significant challenge to society.
Frontiers in Food Policy: Perspectives on Sub-Saharan Africa
December 2013
Frontiers in Food Policy: Perspectives on sub-Saharan Africa is a compilation of research stemming from the Global Food Policy and Food Security Symposium Series, hosted by the Center on Food...
The challenge to detect and attribute effects of climate change on human and natural systems
August 2013
Anthropogenic climate change has triggered impacts on natural and human systems world-wide, yet the formal scientific method of detection and attribution has been only insufficiently described....
Global crop exposure to critical high temperatures in the reproductive period: historical trends and future projections
June 2013
Video abstract Long-term warming trends across the globe have shifted the distribution of temperature variability, such that what was once classified as extreme heat relative to local mean...
Estimating the world's potentially available cropland using a bottom-up approach
June 2013
Previous estimates of the land area available for future cropland expansion relied on global-scale climate, soil and terrain data.
Errors in climate datasets and their effects on statistical crop models
March 2013
Although weather data are widely acknowledged to contain measurement errors, the implications of these errors for models that relate weather to yields have not been adequately examined.
The critical role of extreme heat for maize production in the United States
March 2013
Statistical studies of rainfed maize yields in the United States and elsewhere have indicated two clear features: a strong negative yield response to accumulation of temperatures above 30 °C (or...
Simulated hydroclimatic impacts of projected Brazilian sugarcane expansion
March 2013
Sugarcane area is currently expanding in Brazil, largely in response to domestic and international demand for sugar-based ethanol.
Reduction of transpiration and altered nutrient allocation contribute to nutrient decline of crops grown in elevated CO2 concentrations
March 2013
Plants grown in elevated [CO2] have lower protein and mineral concentrations compared with plants grown in ambient [CO2].
Climate adaptation as mitigation: the case of agricultural investments
February 2013
Successful adaptation of agriculture to ongoing climate changes would help to maintain productivity growth and thereby reduce pressure to bring new lands into agriculture.
