. Global warming boosts crop disease

Paris (AFP) Aug 14, 2007
Global warming will fuel a disease that annually causes hundreds of million dollars in damage to rapeseed plants, used to make canola oil, according to a study released Tuesday.

Using weather-based computer models, researchers in Britain predicted that climate change will expand the range and increase the severity of phoma stem canker, which already accounts for 900 million dollars (650 million euros) in losses each year.

The study, published in the Royal Society journal Interface, found that warmer winters have significantly advanced the date of stem canker appearance in spring, giving it more time to spread before harvest.

Eleven of the past 12 years rank among the dozen warmest years on record, while mean global atmospheric temperature have risen by 0.8 C (1.44 F) over the last century.

Plant pathologist Neal Evans, who led the research, forecast that the disease would move from England north to Scotland, where it does not currently exist.

The computer model "was developed as a tool to help guide fungicide applications timing by farmers," he said. "We realised we could extend its use ... to examine how global warming might impact on future epidemics."

The top rapeseed growers in the world are China, Canada, India, Germany, France and Britain, accounted for nearly 80 percent of worldwide harvests.

The United Nations authority on climate change has said earlier this year human activity is almost certain to blame for global warming, and warned that the Earth's average surface temperature could rise between 1.1 and 6.4 degrees by 2100.

Change On The Range
Madison WI (SPX) Aug 14, 2007
In the Southwestern U.S., land managers face equally critical and difficult decisions when it comes to their ranges. The region is known for its climate variability which has strong influences and impacts on range conditions. Access to the latest climate and range science information is vital for managers to make effective short and long-term decisions. An experiential learning exercise was held at a meeting in January, 2006 to open communication between land managers and scientists about climate and range science concepts.
