  • 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 ...

  • Rising heat hits Indian wheat crop

    Researchers in the UK have established a link between changing climate and agriculture that could have significant consequences for food supplies in South Asia. They have found evidence of a relationship between rising average temperatures in India and reduced wheat production, which was increasing until about a decade ago but has now stopped. The researchers, Dr ...

  • Crop performance matters when evaluating GHGs

    Measuring the emission of greenhouse gases from croplands should take into account the crops themselves. That’s the conclusion of a study in the September-October issue of the Journal of Environmental Quality, which examined the impact of farm practices such as tillage on the greenhouse gas, nitrous oxide (N2O). Expressing emissions per unit of crop yield rather than on a more conventional ...

  • Hawaii is genetically engineered crop flash point

    You can trace the genetic makeup of most corn grown in the U.S., and in many other places around the world, to Hawaii. The tiny island state 2,500 miles from the nearest continent is so critical to the nation's modern corn-growing business that the industry's leading companies all have farms here, growing new varieties genetically engineered for desirable traits like insect and drought ...

  • Where is your soil water? Crop yield has the answer

    Crop yield is highly dependent on soil plant-available water, the portion of soil water that can be taken up by plant roots. Quantitative determination of the maximum amount of plant-available water in soil using traditional methods on soil samples remains challenging, especially at the scale of an entire field. However, a map of plant-available water capacity for a field would be instrumental in ...

  • Could sun-reflecting crops help keep us cool?

    Temperatures in central Europe, central Asia and North America could be reduced by 1°C in the summer, if crops with extra-reflective foliage were chosen, according to a new study. Such crops could reflect sunlight back into space and reduce regional warming by one fifth of projected temperature rises. Many suggestions have been proposed to curb rising temperatures under a changing climate. These ...

  • Mixed crop-livestock farming could help adaptation in Africa

    According to new research, African farms with both crops and livestock could be more resilient to climate change than farms that only grow crops. The research suggests that policy makers should support farmers in making the switch to integrated farming. The Intergovernmental Panel on Climate Change (IPCC) has indicated that agriculture in tropical under-developed countries is the most vulnerable ...

  • Global Land Temperatures Warmest Ever in January, April

    GENEVA, Switzerland, August 8, 2007 (ENS) - Global land surface temperatures for January and April will likely be ranked as the warmest since recordkeeping began in 1880, the United Nations World Meteorological Organization reported Tuesday. 'Weather and climate are marked by record extremes in many regions across the world since January 2007,' the WMO said.The global weather ...

  • Rising temperatures take their toll on rice pest

    A warming climate and occasional extreme high temperature events in tropical countries are likely to limit both the survival and distribution of the brown planthopper, a pest that has devastated rice crops in India, Indonesia, Thailand and Vietnam, according to UK researchers. The scientists, based at the ...

  • Better water management could improve global crop production

    A new global study is the first to quantify the potential of water management strategies to increase crop production. It indicates that a combination of harvesting run-off water and reducing evaporation from soil could increase global crop production by 20 per cent. The EU has recognised the impact of climate change on water and the subsequent effects on agriculture in its white paper on ...

  • ClimateMinder and McGrath Family Farms Deploy Crop and Irrigation Monitoring and Control Solution

    McGrath Family Farms' owner monitors his field, environmental and crop conditions from a cell phone OXNARD, Calif., - ClimateMinder announced today the deployment of its crop and irrigation monitoring and control solution for McGrath Family Farms.  This system collects and monitors field, environmental and crop conditions from sensors in the field. Phil McGrath, owner of McGrath Family Farms ...


  • Maintaining food crop diversity: an interview with Gary Paul Nabhan

    Guest author Fred Bahnson interviewed Gary Paul Nabhan, a lecturer, food and farming advocate, folklorist, and conservationist who lives and farms in the U.S. Southwest. Nabhan discusses his new book, the future of agriculture, and how 1,400-year-old Lebanese farming techniques influence his land ethic. Tell me about your latest book, Where Our Food Comes From-Retracing Nikolay Vavilov's ...

  • The importance of measuring and monitoring soil moisture

    Crop irrigation uses more than 70% of the world’s water, and thus, improving irrigation efficiency is decisive to sustain the food demand from a fast-growing world population.* In future measuring and monitoring soil moisture will get more and more important to meet the needs of an increasing demand for food. Eijkelkamp offers solutions with a wide range of ...

  • Record September Temperatures Extend Southeast Drought

    ASHEVILLE, North Carolina, October 17, 2007 (ENS) - Temperatures in September 2007 were the eighth warmest on record, hot enough to break 1,000 daily high records across the United States, say scientists at NOAA's National Climatic Data Center in Asheville. The global surface temperature was the fifth warmest on record for September, and the extent of Arctic Sea ice reached its lowest ...

  • High temperatures `make wheat old before its time`

    Global warming can cause premature ageing in wheat, according to computer modelling studies of the crop's response to growing conditions in northern India. The effects of warming on wheat growth and grain size are far worse than previous crop models indicated, David Lobell, assistant professor in ...

  • Meeting the 2 Degree Global Temperature Goal Can be Done – UNEP

    ‘Too Little, Too Late’ could be one way to sum up the key message in the latest United Nations Emissions Gap Report assessing what is needed to keep global temperature rise to below 2°C by 2050. But in fact, the message is far more subtle, and more positive than one might assume from reading the press headlines. The 2013 Emissions Gap Report, released by the UN Environment ...

  • Peatlands are Quick and Cost-Effective Measure to reduce 10% of greenhouse emissions

    Clearing, draining and setting fire to peatlands emits more than 3 billion tonnes of carbon dioxide every year - equivalent to 10% of global emissions from fossil fuels, according to Assessment on Peatlands, Biodiversity and Climate Change, the first comprehensive global assessment of the link between peatland degradation and climate change. 'Just like a global phase out of old, energy guzzling ...

  • Rapid action needed to help protect food supplies in vulnerable regions

    Agriculture is vulnerable to climate change, and in order to protect food security, food production will have to adapt to rising temperatures and unpredictable changes in rainfall. Agriculture in poorer countries with harsh climate conditions is likely to be most affected. New research predicts how these vulnerable areas are likely to be affected by climate change in the next 20 years. The ...

  • Comparing N2O emissions from organic and mineral fertilisers

    A recent study compares the effects of organic, 'natural' fertilisers, such as compost, with mineral, synthetic fertilisers, such as urea, on N2O emissions from Mediterranean soil. It suggests that there is little difference between the fertilisers, but that pig slurry offers the best overall balance in terms of emissions and crop yield. Nitrous oxide (N2O) is a powerful greenhouse gas (GHG). ...
