• The Information Age Is Starting to Transform Fishing Worldwide

    The post-industrial area – with its robots, sensors, artificial intelligence, and machine learning — has transformed manufacturing and farming. Commercial fishing, one of the oldest industries in the world, is a stark exception, with industrial fishing, factory ships, and deep-sea trawlers still the dominant hunting mode in much of the world. This approach has led to overfishing, stock depletions, habitat destruction, the senseless killing of unwanted by-catch and wastage of as much as 30% to 40% of landed fish. But these patterns are starting to change.

  • New Network to Improve Biosecurity in Livestock

    Health and welfare, safety and sustainability are crucial elements for ensuring the future of livestock production. Biosecurity aims to prevent the introduction and spread of pathogens within and between farms and, consequently, results in better welfare, increased food safety and better sustainability. A new network to improve biosecurity in livestock.

  • Redefining the Longest Drought

    Maps of the American West have featured ever darker shades of red over the past two decades. In some areas, conditions have blown past severe and extreme drought into exceptional drought. But rather than add more superlatives to the descriptions, one group of scientists believes it’s time to reconsider the very definition of drought.

  • Food Security During a Nuclear Winter

    A nuclear war would cause global blockage of the sun for several years due to injections of black carbon soot into the upper atmosphere, covering most of the planet with black clouds. This could result in less than 40 percent of normal light levels near the equator and less than 5 percent normal light levels near the poles. Research focuses on how meeting food security and nutrition in post-catastrophe conditions, which could last 15 years in some wet tropical forests.

  • Could The War in Ukraine Trigger a Global Food Crisis?

    The effects of the war in Ukraine are already being felt across the world, from rocking world energy markets to spurring a growing refugee crisis in Europe. But the conflict could have more ripple effects, including sparking a global food crisis.

  • The War in Ukraine Is Creating a Massive Grain Shortage

    Together, Russia and Ukraine account for 30 percent of the world’s exported wheat, and the Agricultural Market Information System—an international group focusing on global food-policy initiatives—estimates that 25 countries source at least half of their supplies from the two countries. Grain exports from the war-torn region have largely stalled, as shipping ports have closed, farmland has been ruined, and farmers have been conscripted into service.

  • Food Crisis Due to Ukraine War Calls for Demand-Side Action

    The global food system is impacted by the war in Ukraine, adding to the direct humanitarian and security crisis caused by the Russian aggression. Ukraine and Russia are major producers of grains and fertilizers. Experts say that focusing on short-term supply-side solutions is not the way to go. Rather, changes to the demand side of the global food system can lead to both a more resilient and more sustainable global food system.

  • Accelerated Impact of Climate Change on Human Wellbeing, Nature

    Increased heatwaves, droughts and floods are already exceeding plants’ and animals’ tolerance thresholds, driving mass mortalities in species such as trees and corals. These weather extremes are occurring simultaneously, causing cascading impacts that are increasingly difficult to manage. They have exposed millions of people to acute food and water insecurity.

  • How a Two-century Megadrought Gap Set Up the West for Its Water and Climate Crisis

    Since the turn of the 21st century, researchers probing evidence locked in tree rings and other clues to past climate conditions have been building an increasingly unnerving picture of southwestern North America as prone to deep, prolonged droughts. Megadrought is the emerging term for the worst of these extreme dry spells — those lasting two decades or more.

  • Co-Occurring Droughts May Threaten Global Food Security

    Droughts occurring at the same time across different regions of the planet could place an unprecedented strain on the global agricultural system and threaten the water security of millions of people, according to a new study.

  • Urban Britain’s Potential as a “Grow Your Own” Nation

    Britain’s towns and cities have the potential to support an urban agricultural revolution that would help meet the dietary needs of a growing population, boost the nation’s health and wellbeing, as well as reduce reliance on imports.Britain’s towns and cities have the potential to support an urban agricultural revolution that would help meet the dietary needs of a growing population, boost the nation’s health and wellbeing, as well as reduce reliance on imports.

  • Nuclear War's Smoke Would Cause Climate Change, Threatening Global Food Supplies

    Nuclear war would cause many immediate fatalities, but smoke and soot from the resulting fires would also cause climate change lasting up to fifteen years, threatening worldwide food production and human health, according to a new study.

  • Current Southwest Drought Is a Preview of Things to Come

    Scientists found that the record-low precipitation that kicked off the unprecedented drought parching the U.S. Southwest since 2020 could have been a fluke—just the rare bad luck of natural variability. But the drought would not have reached its current punishing intensity without the extremely high temperatures brought by human-caused global warming.

  • Small Increases in Greenhouse Gases Will Lead to Decades-Long “Megadroughts” in U.S. Southwest

    Recent NOAA-funded research found that even small additional increases in greenhouse gas emissions will make decades-long “megadroughts” – similar to the drought which has descended on the U.S. southwest nearly twenty years ago — more common.

  • New Ways to Assess Climate Change Impacts on Agriculture

    Scientists agree climate change has a profound impact on U.S. agricultural production, but estimates vary, making it hard to develop mitigation strategies. Two agricultural economists take a closer look at how choice of statistical methodology influences climate study results. They also propose a more accurate and place-specific approach to data analysis.
