Worldwide, smoke from landscape fires contributed to an average of 339,000 deaths per year between 1997 and 2006, according to new research published in Environmental Health Perspectives and released today during the Annual Meeting of the American Association for the Advancement of Science (AAAS). Sub-Saharan Africa and Southeast Asia were the hardest hit by fire-smoke deaths, with an estimated annual average of 157,000 and 110,000 deaths, respectively, attributable to landscape fire smoke...

University of Oregon-led research team urge a retooling of thought on fire-management practices The American West has seen a recent increase in large wildfires due to droughts, the build-up of combustible fuel, or biomass, in forests, a spread of fire-prone species and increased tree mortality from insects and heat. In a paper appearing online Feb. 14 in the Proceedings of the National Academy of Sciences, a 12-member research team warns that these conditions may be "a perfect storm"...

TAU researchers use organic polymer to protect scorched soil from erosion Wildfires cause tragic losses to life, property, and the environment. But even after the fire rages, the damage is far from done. Without vegetation, bare, burnt soil lies vulnerable to erosion, which can impede efforts towards natural forest regeneration. Now Assaf Inbar, a graduate student at Tel Aviv University's Porter School of Environmental Studies, together with his supervisors Prof. Marcelo Sternberg of...

Image 1 - Rapid Rise In Canada Wildfires?

Ecologists show for the first time threshold values for natural wildfires Large forest regions in Canada are apparently about to experience rapid change. Based on models, scientists can now show that there are threshold values for wildfires just like there are for epidemics. Large areas of Canada are apparently approaching this threshold value and may in future exceed it due to climate change. As a result both the area burnt down annually and the average size of the fires would increase,...

The Environmental Sciences Network Life-Sciences.net features the latest scientific publications in this discipline. The most recently featured articles deal with the effects of temperature and precipitation on vegetation in the upper catchments of the Yellow River in China, and spatial data management priorities for assessment of Europeâs coasts and seas. (PRWEB) November 23, 2011 The Environmental Sciences category of the Life-Sciences Magazine covers the external physical...

Ocean Temps Can Predict Amazon Fire Season Severity

By analyzing nearly a decade of satellite data, a team of scientists led by researchers from the University of California, Irvine and funded by NASA has created a model that can successfully predict the severity and geographic distribution of fires in the Amazon rain forest and the rest of South America months in advance. Though previous research has shown that human settlement patterns are the primary factor that drives the distribution of fires in the Amazon, the new research...

Prediction method could help protect rainforests around the globe Tiny temperature changes on the Atlantic and Pacific oceans provide an excellent way to forecast wildfires in South American rainforests, according to UC Irvine and other researchers funded by NASA. "It enables us three to five months in advance to predict the severity of the fire season," said UCI assistant project scientist Yang Chen, lead author of a paper that will be published Friday, Nov. 11, in the journal Science....

A system built by University of Cincinnati experts around an unmanned aerial vehicle has faced a real-world test in a West Virginia controlled forest burn, and proved its usefulness. Wildfires kill and, too often, fatalities are caused by a lack of situational awareness, said Kelly Cohen. Timely information can prevent wildfire deaths, especially among first responders, said Cohen, associate professor of aerospace engineering & engineering mechanics at the University of Cincinnati....
