        • Food securityGame-Changing Technologies to Transform Food Systems

          In the next three decades, the world will need a 30–70 percent increase in food availability to meet the demand from an increasing population. In addition, the global food system will need to change profoundly if it is going to provide humanity with healthy food that is grown sustainably in ways that are not only resilient in the face of climate change but also do not surpass planetary boundaries. According to new research, a pipeline of disruptive technologies could transform our food systems, ecosystems, and human health, but attention to the enabling environment is needed to realize their potential.

          A team of fisheries scientists and marine policy experts examined how climate change is affecting the ocean environment and found that the changing conditions will likely result in increased fisheries-related conflicts and create new challenges in the management of global fisheries.

        • Water securityChanges in Snowmelt Threaten Farmers in Western U.S.

          Farmers in parts of the western United States who rely on snowmelt to help irrigate their crops will be among the hardest hit in the world by climate change, a new study reveals. The study pinpointed basins globally most at risk of not having enough water available at the right times for irrigation because of changes in snowmelt patterns. Two of those high-risk areas are the San Joaquin and Colorado river basins in the western United States.

        • Food securityIrrigation Expansion Could Feed 800 Million More People

          Agriculture, which accounts for 90 percent of global water use, is the largest driver of water scarcity worldwide, and it is often the most vulnerable and disadvantaged populations that suffer the severest consequences. A new study suggests that there is enough locally available water to expand irrigation over 140 million hectares of agricultural lands.

          With lockdowns ordered to contain the COVID-19 pandemic, there are fears of food shortages caused by panic buying and supply chain disruptions. Paul Teng writes in SciDev.Net that recent announcements by some countries that they are initiating export restrictions of food products or reviewing export agreements have brought back memories of the 2007—2008 food crisis when there was an interruption to global food supply chains as several key countries limited exports of rice and wheat. This unleashed a series of events around the world, including food shortages, price spikes and civil disobedience in over 30 countries.

          According to the U.N. Food and Agriculture Organization (FAO), the COVID-19 pandemic is impacting the world’s food systems and disrupting regional agricultural trade and value chains. The FAO has warned that food shortages are a real risk in the coming months. This global health crisis will test our food and trade systems in ways never experienced before.

        • Food securityWe Simulated How a Modern Dust Bowl Would Impact Global Food Supplies and the Result Is Devastating

          By Miina Porkka, Alison Heslin, and Matti Kummu

          When the southern Great Plains of the United States were blighted with a series of droughts in the 1930s, it had an unparalleled impact on the whole country. Combined with decades of ill-advised farming policy, the result was the Dust Bowl. Massive dust storms began in 1931 and devastated the country’s major cereal producing areas. But what consequences would a disruption like the Dust Bowl have now, when the Great Plains of the U.S. are not just the breadbasket of America, but a major producer of staple cereals that are exported around the world?

          By Kevin Krajick

          With the western United States and northern Mexico suffering an ever-lengthening string of dry years starting in 2000, scientists have been warning for some time that climate change may be pushing the region toward an extreme long-term drought worse than any in recorded history. A new study says the time has arrived: a megadrought as bad or worse than anything even from known prehistory is very likely in progress, and warming climate is playing a key role.

        • Food securityHow Will The COVID-19 Pandemic Affect Global Food Supplies? Here's What We Know.

          That strawberry you’re eating while self-isolating from the coronavirus? Chances are it came from a farm. Or it may have come from a large agricultural operation many, many kilometers away from your home, harvested by hand, possibly by migrant workers brought in from other towns, cities, or even countries. But can that system continue to bring you strawberries as the global coronavirus pandemic continues? Or bread? Pasta? Cooking oil?

        • Food securityImpact of a Second Dust Bowl Would Be Felt Worldwide

          The American Dust Bowl of the 1930s - captured by the novels of John Steinbeck - was an environmental and socio-economic disaster that worsened the Great Depression. The Dust Bowl was an extreme event. But due to climate change, massive crop failures are more likely to happen again in the future. A catastrophic shock to U.S. agriculture would deplete reserves, including those of other countries.

        • FloodsComparing Floodplain Protection Today to Predicted Future Flood Losses

          A new study seeks to answer an important question related to flooding in the United States – pay now to protect undeveloped areas that are likely to flood in the future or allow developments to go ahead and pay for damage when it occurs.

        • Climate & businessThe Challenges Facing Fisheries Climate Risk Insurance

          The world’s first “Fisheries Index Insurance” scheme, launched by an international consortium in July, is a sovereign-level instrument designed to protect Caribbean fishing communities from extreme weather events which may become more frequent and intense due to climate change. But insurance schemes with the potential to improve the resilience of global fisheries face a host of future challenges, researchers say.

        • Food securityNew World Map Rates Food Sustainability for Countries Across the Globe

          Increased awareness of how human diets exacerbate climate change – while failing to properly nourish more than 800 million people – makes a better understanding of food systems a global priority. Global initiatives now call for us to transform our diets – for our health and the health of the planet – to help make food systems “sustainable.”

        • Food securityClimate Change Could Cause Drought in Wheat-Growing Areas

          In a new study, researchers found that unless steps are taken to mitigate climate change, up to 60 percent of current wheat-growing areas worldwide could see simultaneous, severe and prolonged droughts by the end of the century. Wheat is the world’s largest rain-fed crop in terms of harvested area and supplies about 20 percent of all calories consumed by humans.

          In an effort to enhance compliance with the Food Safety and Modernization Act (FSMA), the Food and Drug Administration (FDA) launched a new dashboard that will track and monitor how companies are implementing parts of the law, and how those changes are affecting the food safety system.
