• Global Warming Increased U.S. Crop Insurance Losses by $27 Billion in 27 Years

    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.

  • Lawmakers Looking to Curb Chinese Ownership of U.S. Farmland

    The Chinese threat to American food security, so far, would seem minimal: As of December 2019, Chinese agricultural real estate holdings in America totaled about 78,000 hectares, which is about 0.02 percent of America’s roughly 3.6 million square kilometers of total farmland. Still, U.S. lawmakers are seeking to restrict Chinese purchases of American farmland amid fears that such purchases could ultimately pose a threat to the U.S. food supply chain.

  • Building Resilience against Agroterrorism, Agro-crime Threats

    Agroterrorism and agro-crime constitute a considerable threat to the economy and public health. To effectively deal with agroterror or agro-crime using pathogens of animal origin, it is crucial that veterinary and law enforcement agencies are equipped to work together to jointly plan, prepare, and respond to animal disease outbreaks.

  • Creating More Resilient Supply Chains Through Nature-Inspired Design

    Supply chains work a lot like food webs in natural ecosystems, in which biodiversity allows for adaptation during disruptions. The analogy turned out to be relevant particularly in looking at “black swan” events, which are unpredictable and hard to protect against—and for which adaptation, not prevention, is the main defense.

  • Drought and Record Heat in the West: The Climate Change Connection

    As intense drought and record heat make their way across the Western U.S., the deep and devastating impacts of this extreme weather are clear — electric utilities are asking consumers to ration power and water, farmers are scrambling to sell or save their produce, and officials are making plans to keep their communities safe and cool. All before true summer weather arrives. Research shows that these extreme events are expected to continue as our climate changes.

  • Solar Geoengineering May Alleviate Impacts of Global Warming on Crops

    Solar geoengineering — putting aerosols into the atmosphere to reflect sunlight and reduce global warming — is not a fix-all for climate change but it could be one of several tools to manage climate risks. A growing body of research has explored the ability of solar geoengineering to reduce physical climate changes. But much less is known about how solar geoengineering could affect the ecosystem and, particularly, agriculture.

  • New Tool Could Guide Floodwater Management and Combat Ongoing Drought

    Using a new computer framework, scientists are able to project future floodwaters under a changing climate. The approach could help California water managers plan for and redirect floodwaters toward groundwater aquifers, alleviating both flood and drought risks.

  • Interstate Water Wars Are Heating Up Along with the Climate

    Interstate water disputes are as American as apple pie. States often think a neighboring state is using more than its fair share from a river, lake or aquifer that crosses borders. Climate stresses are raising the stakes.

  • Climate Change Has Cost 7 years of Ag Productivity Growth

    Despite important agricultural advancements to feed the world in the last 60 years, a Cornell-led study shows that global farming productivity is 21 percent lower than it could have been without climate change. This is the equivalent of losing about seven years of farm productivity increases since the 1960s.

  • Adaptation, Not Irrigation Recommended for Midwest Corn Farmers

    A warming climate may not increase water demand for Midwest crops that may instead be adapted through soil management to changing air temperatures and moisture, say researchers helping farmers manage the challenge.

  • Food Export Restrictions Could Skyrocket Global Food Crop Prices

    Recent events such as the Covid-19 pandemic, locust infestations, drought and labor shortages have disrupted food supply chains, endangering food security in the process. A recent study shows that trade restrictions and stockpiling of supplies by a few key countries could create global food price spikes and severe local food shortages during times of threat.

  • Artificial Intelligence for Food Security

    With a global population of around 7.8 billion people in 2021, there are at least a billion people who suffer chronic hunger and malnutrition. This crisis is a result of inefficient food production and distribution systems. AI, or artificial intelligence, is attracting great attention across many industries, even food production, according to new research.

  • Israeli locust slayers train Ethiopians to save crops

    The enemies are huge armies of desert locusts destroying farm and grazing lands across nine East African countries. In Ethiopia alone, the locusts have conquered three million acres since January. Experts from Israel bring equipment and knowhow enabling Ethiopian farmers to protect their fields from deadly desert locust swarms.

  • Nuclear War could Take a Big Bite Out of the World's Seafood

    A new study reveals the damage that a nuclear war might take on wild-caught seafood around the world, from salmon and tuna to the shrimp in shrimp cocktails. The aftermath of such a conflict could put a major strain on global food security, an international team of scientists reports. The group estimates that a nuclear war might cut the amount of seafood that fishing boats are capable of bringing in worldwide by as much as 30 percent.

  • Global Food Production Poses an Increasing Threat to the Climate

    The significant use of nitrogen fertilizers in the production of food worldwide is increasing concentrations of nitrous oxide in the atmosphere—a greenhouse gas 300 times more potent than carbon dioxide—which remains in the atmosphere longer than a human lifetime.
