• Food securityGlobal warming could help crops’ productivity

    Many scientists fear that global warming will hit staple food crops hard, with heat stress, extreme weather events, and water shortages. On the other hand, higher levels of carbon dioxide — the main cause of ongoing warming — is known to boost many plants’ productivity, and reduce their use of water. So, if we keep pouring more CO2 into the air, will crops fail, or benefit? A new study tries to disentangle this complex question. It suggests that while greater warmth will reduce yields of some crops, higher CO2 could help mitigate the effects in some regions, unless other complications of global warming interfere.

  • Emerging threats Soil’s carbon storage could help limit impact of climate change

    Soils currently lock away around 2.4 trillion tons of greenhouse gases, which are stored underground as stable organic matter. Researchers say the world’s soils could store an extra eight billion tons of greenhouse gases, helping to limit the impacts of climate change. Growing crops with deeper root systems, using charcoal-based composts, and applying sustainable agriculture practices could help soils retain the equivalent of around four-fifths of annual emissions released by the burning of fossils fuels, the researchers say.

  • Food safetyPaper-based test to help prevent food poisoning

    The foodborne bacteria Salmonella alone led to nearly 20,000 hospitalizations and almost 400 deaths in 2013. Economists estimate that the treatment of all these patients and the related productivity losses cost more than $3 billion annually. And those numbers account for just one of the fifteen pathogens responsible for most of the food poisoning cases. Scientists have developed a simple, paper-based test that could help detect pathogens hitchhiking on food before they reach store shelves, restaurants and, most importantly, our stomachs.

  • Food safety2010 Maryland food poisoning outbreak traced to Asian strain of seafood pathogen

    V. parahaemolyticusis the most important cause of seafood poisoning in the United States. Approximately 4,500 cases occur annually in the United States, according to the Center for Disease Control and Prevention. The number of cases has risen in recent years, possibly do to the warming climate.

  • Food securityStarvation is only one crop breeding cycle away

    Global population growth, urbanization, and a changing climate mean staple food crops will need to achieve much higher yields in the near future. New research proposes genetic engineering solutions to improve photosynthetic efficiency of food crops, boosting yield under higher temperatures and carbon dioxide levels. Because it can take twenty to thirty years of breeding and product development efforts before new crops are available to farmers, those efforts must start now.

  • Food securityNew biotechnology improves crop performance

    With the world’s population exploding to well over seven billion, feeding the human race is getting even more challenging. Increasing the yield from crops such as wheat, maize, rice and barley, is paramount to growing enough food. In addition, crop production is now affected by stressors such as drought, climate change, and the salinization of fields — presenting obstacles to our future food supply. Rsearchers have discovered a way to enhance a plant’s tolerance to stress, which in turn improves how it uses water and nutrients from the soil. These improvements increase plant biomass and yield.

  • Food security Global warming increases rainfall in world's driest areas

    Global warming will increase rainfall in some of the world’s driest areas over land, with not only the wet getting wetter but the dry getting wetter as well — a phenomenon that could lead to more flash flooding.

  • Food securityImpact of climate change on agriculture may be underestimated

    Studies of how climate change might affect agriculture generally look only at crop yields — the amount of product harvested from a given unit of land. But climate change may also influence how much land people choose to farm and the number of crops they plant each growing season. A new study takes all of these variables into account, and suggests researchers may be underestimating the total effect of climate change on the world’s food supply.

  • Food securitySyria’s 1998-2012 drought likely its most severe in more than 900 years

    In the years before the Syrian conflict erupted, the region’s worst drought on record set in across the Levant, destroying crops and restricting water supplies in the already water-stressed region. A new study shows that that drought, from 1998 to 2012, was not just the most severe in a century of record-keeping — it was the Levant’s most severe drought in at least 500 years and likely more than 900 years.

  • Food securityResources used for biofuel reduce resources available for food production

    As strategies for energy security, investment opportunities and energy policies prompt ever-growing production and consumption of biofuels like bioethanol and biodiesel, land, and water that could otherwise be used for food production increasingly are used to produce crops for fuel. A new study shows about a third of the world’s malnourished population could be fed by using resources now used for biofuel production.

  • Food securityClimate change impact on food production could cause 500,000 extra deaths in 2050

    Climate change could kill more than 500,000 adults in 2050 worldwide due to changes in diets and bodyweight from reduced crop productivity. The research, published yesterday in The Lancet, is the strongest evidence yet that climate change could have damaging consequences for food production and health worldwide. The study found that by 2050, reduced fruit and vegetable intake could cause twice as many deaths as under-nutrition, and that three-quarters of all climate-related deaths due to changes in food production are estimated to occur in China and India.

  • Food securityIntegrating markets to offset climate-related food insecurity

    Global market integration is key to buffering future commodity prices and food security from the negative effects of climate change on agriculture. Rising temperatures and an increase in extreme weather events will likely have adverse impacts on global crop production, leading to higher food prices and food scarcity. But global markets that have the ability to deliver food where it is needed most could help offset these consequences.

  • Food securityExtreme weather likely to result in “food shocks”

    A panel of British and American researchers, speaking at the annual meeting of the American Association for the Advancement of Science (AAAS) in Washington, D.C., presented updated research revealing how extreme events which affect the food system are increasingly likely to occur, resulting in “food shocks.”

  • Food security Food for billions: Inland fisheries and global food security

    Inland capture fisheries are much more crucial to global food security than realized, according to the first global review of the value of inland fish and fisheries. The review shows that although aquaculture and inland capture fisheries contribute more than 40 percent of the world’s reported finfish production, their harvest is greatly under-reported and value is often-ignored. Topping the list of the value of inland fish and fisheries is food and economic security: these fisheries provide food for billions of people and livelihoods for millions worldwide. They are a primary animal protein consumed by many of the world’s rural poor, especially those in developing countries.

  • Food securityNurturing the future of agriculture

    Climate change and man-made events put global food security at risk. But researching how plants produce seeds and evolve could help us find new ways to ensure food security. For the first time in its history, the Global Seed Vault on the Svalbard Islands, Norway, has authorized a withdrawal. It was requested in 2015 by Syria, a country where the war is endangering the local agricultural seed collections.
