  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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). ...

  • UF/IFAS research finds ways to save water, strawberries and money during cold temps

    Florida’s strawberry producers must protect their multimillion-dollar annual crop from freeze damage. Traditional methods involve constant spraying of water during a cold snap. Growers are looking for ways to use less water, yet produce the same amount of crop. New University of Florida research shows growers can keep using both their current sprinkler spacing and low pressure or enhanced ...

  • Predictions for the storage season ahead

    Current weather forecasts predict that rain and unsettled conditions are likely as we move into the autumn, and this may create challenges for growers with concerns about potato storage and disease control this season. Store cleanliness and hygiene should also be top priority for growers before harvest. “I can’t stress enough the value of ensuring the correct ...

  • Maize seedlings predict drought Tolerance

    Scientists have developed a new method for measuring drought tolerance in maize. By comparing the shoot-to-root ratio in seedlings stressed by low water, scientists can predict whether a plant has the right mix of genes for adapting to drought conditions. The ideal drought-resistant maize should have a higher ratio of root surface area compared to leaves and stems. Developing enough adult plants ...
