• Food securitySoils Could Be Affected by Climate Change, Impacting Water and Food

    Coasts, oceans, ecosystems, weather and human health all face impacts from climate change, and now valuable soils may also be affected. Climate change may reduce the ability of soils to absorb water in many parts of the world, according to a Rutgers-led study. And that could have serious implications for groundwater supplies, food production and security, stormwater runoff, biodiversity and ecosystems.

  • Food securityHumanity’s Ability to Feed Itself Under Growing Threat

    A new UN report warns that the world’s land and water resources are being exploited at “unprecedented rates,” and that the combination of this increasingly more rapid exploitation with climate change is putting dire – and threatening — pressure on the ability of mankind to feed itself.

  • Public healthThe Challenge: Feeding 11 billion People Without Spread Infectious Disease

    Within the next 80 years, the world’s population is expected to top 11 billion, creating a rise in global food demand — and presenting an unavoidable challenge to food production and distribution. But a new study describes how the increase in population and the need to feed everyone will also, ultimately, give rise to human infectious disease, a situation the authors of the paper consider “two of the most formidable ecological and public health challenges of the 21st century.

     

  • SuperbugsMajor drop in antibiotics for food animals in U.S.

    New data released the other day by the U.S. Food and Drug Administration (FDA) shows the amount of medically important antibiotics sold for use in food-producing animals in the United States is on the decline. The FDA report shows that domestic sales and distribution of medically important antibiotics for use in livestock decreased by 33 percent from 2016 through 2017, and by 43 percent since sales peaked in 2015.

  • Food securityMidwest at risk: Big-picture look at climate change impact on U.S. agriculture

    A new study shows that Midwest agriculture is increasingly vulnerable to climate change because of the region’s reliance on growing rain-fed crops. The researchers set out to assess the impact extreme weather is having on agricultural productivity in the United States. While previous studies have looked at the vulnerability of individual field crops, which make up one-third of the country’s agricultural output, researchers haven’t addressed the whole scope of agricultural production, including livestock, at the national level.

  • Climate threatsU.S. gov.’s climate assessment: U.S. already suffering severe consequences of climate change

    The Fourth National Climate Assessment (NCA4)—a quadrennial report mandated by Congress since 1990—was released Friday. Thirteen federal agencies develop the NCA using the best available science to help the nation “understand, assess, predict and respond to” climate change. The 1,500-page report examines the climate and economic impacts U.S. residents could expect if drastic action is not taken to address climate change. The consequences of global warming for the U.S. economy, infrastructure, food production, water, and public health are already severe, as flooding, droughts, wildfires, rain storms, and hurricanes intensify. Unless warming is arrested, to consequences are only going to get worse.

  • Public healthE coli probe prompts CDC warning to avoid all romaine

    The U.S. Centers for Disease Control and Prevention (CDC) yesterday warned consumers not to eat any romaine lettuce and for retailers and restaurants not to sell or serve it, as US and Canadian officials investigate an Escherichia coli O157:H7 outbreak.

  • Food securityMore people are getting bigger, requiring more food

    Food demand is growing as people get bigger. Feeding a population of 9 billion in 2050 will require much more food than previously calculated. The number of people on Earth could level off at around nine billion in a few years, compared to just over 7.6 billion now. But an average person in the future will require more food than today. Changes in eating habits, attitudes towards food waste, increases in height and body mass, and demographic transitions are some of the reasons.

  • Food securitySevere Caribbean droughts would magnify food insecurity

    Climate change is impacting the Caribbean, with millions facing increasing food insecurity and decreasing freshwater availability as droughts become more likely across the region, according to new research. Since 1950, the Caribbean region has seen a drying trend and scattered multiyear droughts. But the recent Pan-Caribbean drought in 2013-16 was unusually severe and placed 2 million people in danger of food insecurity.

  • Animal diseaseMeasuring global cost of animal diseases

    Across the globe, families depend on livestock animals for milk, meat, eggs, even muscle power. But when a valuable cow or sheep gets sick, farm families face a stark burden affecting not just their herd’s survival, but human health and potential losses for years to come.

  • Food securityThe 1800s Global Famine could happen again

    Researchers have completed the most thorough analysis yet of The Great Drought — the most devastating known drought of the past 800 years — and how it led to the Global Famine, an unprecedented disaster that took 50 million lives. She warns that the Earth’s current warming climate could make a similar drought even worse.

  • Food securityEnvironmentally friendly farming can increase productivity

    A major new study, measuring a global shift towards more sustainable agricultural systems that provide environmental improvements at the same time as increases in food production, shows that the sustainable intensification of agriculture, a term that was once considered paradoxical, delivers considerable benefits to both farmers and the environment.

  • GeoengineeringBlocking sunlight to cool Earth won't reduce crop damage from global warming

    Injecting particles into the atmosphere to cool the planet and counter the warming effects of climate change would do nothing to offset the crop damage from rising global temperatures, according to a new analysis. “Shading the planet keeps things cooler, which helps crops grow better. But plants also need sunlight to grow, so blocking sunlight can affect growth. For agriculture, the unintended impacts of solar geoengineering are equal in magnitude to the benefits,” said the study’s lead author.

  • SuperbugsNew FDA initiative to reduce overuse of antibiotics in animals met with skepticism

    Each year more than 2 million Americans suffer infections from bacteria that cannot be treated by one or more antibiotics—and at least 23,000 die. Approximately 70 percent of all medically important antibiotics in the United States are sold for use in food-producing animals. The U.S. Food and Drug Administration (FDA) announced last week that the agency will soon be implementing a 5-year blueprint to advance antimicrobial stewardship in veterinary settings. The FDA wants to further its efforts to reduce the overuse of antimicrobial drugs and combat the rising threat of antimicrobial resistance. Critics charge the new FDA’s initiative is too timid.

  • Food securityClimate taxes on agriculture may lead to more food insecurity than climate change itself

    New research has found that a single climate mitigation scheme applied to all sectors, such as a global carbon tax, could have a serious impact on agriculture and result in far more widespread hunger and food insecurity than the direct impacts of climate change. Smarter, inclusive policies are necessary instead.
