Mapping crops around the globe is key to estimating production and developing targeted management strategies. New research utilized data from NASA's Global Ecosystem Dynamics Investigation (GEDI) technology and developed an algorithm to distinguish between maize and other crops with high accuracy and produce crop maps across the globe.
Climate expert Marshall Burke joins the World Class podcast to talk through what’s going right, what’s going wrong, and what more needs to be done to translate data on the climate crisis into meaningful policy.
NASA Harvest partners at Stanford’s Center on Food Security and the Environment (FSE) recently published a study on their efforts integrating lidar (Light Detection and Ranging) and optical earth observation (EO) data to improve crop type mapping in areas with low training data availability.
Smoke from wildfires may have contributed to thousands of additional premature births in California between 2007 and 2012. The findings underscore the value of reducing the risk of big, extreme wildfires and suggest pregnant people should avoid very smoky air.
Higher temperatures attributed to climate change caused payouts from the nation’s biggest farm support program to increase by $27 billion between 1991 and 2017, according to new estimates from Stanford researchers. Costs are likely to rise even further with the growing intensity and frequency of heat waves and other severe weather events.
Warnings of another severe wildfire season abound, as do efforts to reduce the risk of ignition. Yet few are taking precautions against the smoke. Stanford experts advise on contending with hazardous air quality.
The analysis estimates pollution reductions between 1999 and 2019 contributed to about 20 percent of the increase in corn and soybean yield gains during that period – an amount worth about $5 billion per year.
Twenty years ago, a Stanford-led analysis sparked controversy by highlighting fish farming’s damage to ocean fisheries. Now a follow-up study takes stock of the industry’s progress and points to opportunities for sustainable growth.
In an article recently published in the Food Sustainability Index, a publication of The Economist, Blue Food Assessment co-chair Roz Naylor emphasizes the need to develop comprehensive food policies that better incorporate food from aquatic spaces.
New management approaches and technology have allowed the U.S. Corn Belt to increase yields despite some changes in climate. However, soil sensitivity to drought has increased significantly, according to a new study that could help identify ways to reverse the trend.
Researchers analyzed the interconnected food, water and energy challenges that arise from the sugar industry in India – the second-largest producer of sugar worldwide – and how the political economy drives those challenges.
The study of sub-Saharan Africa finds that a relatively small increase in airborne particles significantly increases infant mortality rates. A cost-effective solution may lie in an exotic-sounding proposal.
COVID-19 and other looming threats could make it much harder for people to access food. David Lobell, director of Stanford’s Center on Food Security and the Environment, outlines likely scenarios and possible solutions.
