  • Simulating Agricultural Climate Change Scenarios using Controlled Growth Chambers

    Extreme weather, believed to result from climate change and increased atmospheric CO2 levels, is a concern for many. And beyond extreme events, global warming is also expected to impact agriculture.1,2   Although it is expected that climate change will significantly affect agriculture and cause decreases in crop yields, the full effects of climate change ...

  • Crops and Weeds: Global climate change`s first responders

    A team of Agricultural Research Service (ARS) plant physiologists is studying how global climate change could affect food crop production--and prompt the evolution of even more resilient weeds. Lewis Ziska, Richard Sicher and Jim Bunce all work at the ARS Crops Systems and Global Change Laboratory in Beltsville, Md. Over the past several years, the three scientists have conducted research on a ...

  • Climate change and agriculture: food and farming in a changing climate

    Climate change is already affecting the Earth’s temperature, precipitation, and hydrological cycles, with detrimental impacts on U.S. and global agricultural systems. The interaction of these dynamic factors can lead to a decrease in plant productivity, increasing the price for many important agricultural crops. On Wednesday, June 16, 2010, between 10:30-11:30am, in Room 328A of the Senate ...

  • Climate change could impact livestock production

    Land used for livestock grazing; referred to range land in the western U.S. and pasture land in the eastern half of the country, encompasses over 584 million acres of non-Federal land and represents a very complex ecosystem. While the intensity of the management of these lands differs from parcel to parcel, there is no doubt they all play a vital role in livestock production. However, little ...

  • Climate change accelerates maturing of grape in wine production

    “The increase in temperatures and of CO2 levels – the consequences of climate change – accelerates the maturing of grapes in wine production, affecting colour and possibly aromas”. This was the conclusion of the PhD thesis defended by Johann Martínez-Lüscher, undertaken jointly by the University of Navarra and the University of Bordeaux. The biologist ...

  • Fighting climate change with grasslands

    Grasslands have vast untapped potential to mitigate climate change by absorbing and storing CO2, according to a new report by FAO. Pastures and rangelands represent a carbon sink that could be greater than forests if properly managed. Covering some 30 percent of the earth’s ice-free land surface and accounting for 70 percent of its agricultural land, the world’s 3.4 billion ha of grasslands can ...

  • Bhutan faces crop losses from erratic climate

    Agricultural experts in the Himalayan country of Bhutan — a least developed country — are concerned at increasing crop losses in recent years, attributable to global warming. The losses, which began around 2004, are the direct result of increasing pest attacks and disease, erratic rainfall, windstorms, droughts, flash floods and landslides, officials said. The country’s ...

  • GM crops can thrive as climate warms

    Genetically engineering photosynthesis in plants could take advantage of rising global temperatures and increased levels of carbon dioxide, US scientists say. They believe this could achieve much higher yields on the same amount of land and help to stave off the prospect of widespread hunger as human populations increase. Researchers at ...

  • Biofuels could hasten climate change

    A new study finds that it will take more than 75 years for the carbon emissions saved through the use of biofuels to compensate for the carbon lost when biofuel plantations are established on forestlands. If the original habitat was peatland, carbon balance would take more than 600 years. The oil palm, increasingly ...

  • Creating a climate for policy change in Malawi

    A conflict between climate adaptation and food security policies shows we must create the right conditions for change, says Blessings Chinsinga. The adverse effects of climate change on the livelihoods of the rural poor can no longer be ignored. They are threatening to cause tremendous damage to ...

  • Adapting agricultural water to climate change

    This policy brief, published by the Overseas Development Institute (ODI), examines the relationship between climate change, water and food security and outlines potential adaptation strategies and policy priorities for developing countries. Agriculture in developing countries is already under pressure from growing populations, industrialisation and environmental degradation. Climate change is ...

  • Population has bigger effect than climate change on crop yields, study suggests

    Population pressure will be as significant a factor as climate change in reducing crop yields — and thus increasing food insecurity — in West Africa, according to a modelling study. The authors inserted different ...

  • Wild Bee Decline Threatens U.S. Crop Production

    The first national study to map U.S. wild bees suggests they’re disappearing in many of the country’s most important farmlands — including California’s Central Valley, the Midwest’s corn belt and the Mississippi River valley. If losses of these crucial pollinators continue, the new nationwide assessment indicates that farmers will face increasing costs — and ...

  • Supporting climate-friendly food production

    This summer, record temperatures and limited rainfall parched vast areas of U.S. cropland, and with Earth’s surface air temperature projected to rise 0.69 degrees Celsius by 2030, global food production will be even more unpredictable, according to new research conducted by the Worldwatch Institute (www.worldwatch.org). Although agriculture is a major driver of ...

  • Cereal Crops Feeling the Heat

    LIVERMORE, California (ENS) - Warming temperatures since 1981 have caused annual losses of about US$5 billion for six major cereal crops, new research has found. This is the first study to estimate how much global food production already has been affected by climate change. From 1981 to 2002, fields of wheat, corn and barley throughout the world have produced a combined 40 million ...

  • Rainfall changes threaten food production

    The UN’s latest State of Food and Agriculture (SOFA) report warns that rainfall patterns will have changed so drastically by the end of this century that agriculture, forestry and fishing will all be seriously affected. “It will become more and more difficult to harvest crops, rear animals and manage forests and fisheries in the same places and in the same way as before,” says ...

  • Climate change to disrupt soil nutrients in drylands

    The increased aridity expected this century as a result of climate change may disrupt the balance of key soil nutrients with a knock-on effect on soil fertility threatening livelihoods of more than two billion people, a study finds. The drop in nitrogen and carbon concentrations that occurs as soils become dryer could have ...

  • Climate change to hit Saudi`s agriculture, water

    Scientists in Saudi Arabia say that by the end of 2050 parts of the country will be hotter and have reduced precipitation, which could affect agricultural productivity. The work was published in February's issue of the Arabian Journal for Science and Engineering. [1] It predicts that average temperatures in Saudi Arabia could increase by as much as four degrees Celsius, increasing agricultural ...
