Drying of northern wetlands has led to much more severe peatland wildfires and nine times as much carbon released into the atmosphere, according to new research led by a University of Guelph professor. The study, published today in Nature Communications, is the first to investigate the effect of drainage on carbon accumulation in northern peatlands and the vulnerability of that carbon to burning. "Russia, Indonesia and Canada all have abundant peatlands, but they also have been hotspots...

Something's up with the weather in Namibia, say geoscientists Kyle Nichols of Skidmore College in Saratoga Springs, N.Y., and Paul Bierman of the University of Vermont in Burlington, Vt. Nichols and Bierman should know. They're just back from the western mountains and coastal plain of this sparsely populated African country. Usually, western Namibia is a dusty place where the stream beds are sand and the "lakes" are nothing more than flats of dried mud. Not now. This year, rivers...

KUCHING, Sarawak, Malaysia, March 29, 2011 /PRNewswire/ -- The State Government of Sarawak's Agricultural Policy prioritises sustainable management of biodiversity as part of its strategy for the growth of palm oil plantation. Sarawak has a total land mass of 12.4 million hectares, of which 70% is under forest cover and 14% is secondary forest. 13% of the land is used for agriculture and the remaining 3% compromise settlements and water bodies. Currently the state has allocated 700,000...

Indonesia has promised to become a world leader in reducing greenhouse gas emissions. In 2009, the president committed to a 26% reduction in greenhouse gas emissions by 2020 to below 'business-as-usual' levels. Of this total, 14% would have to come from reducing emissions from deforestation or forest degradation. Investments by foreign governments and other bodies are expected to raise total emission reduction from 26% to 41%. While international negotiations on rules about how to reduce...

WALLA WALLA, Wash., Jan. 31, 2011 /PRNewswire/ -- Organix, Inc. of Walla Walla, Washington announced today that it has begun shipping its horticultural peat moss alternative, RePeet(TM), from a dairy in Yakima County, Washington. RePeet(TM) is manufactured from dairy fiber resulting from the anaerobic digestion of manure for renewable energy production. An anaerobic digester acts like a short term, renewable peat bog - submerging the fiber for up to 45 days. Organix further processes the...

CARRABELLE, Fla., April 14 /PRNewswire/ -- For three hours, firefighters from the Carrabelle, Lanark and Apalachicola, Florida, filled sand bags to build a forty-five foot long storm surge wall. The training exercise was conducted using newly developed bright blue and yellow high tech sand bags. The new wedge-shaped, wide mouth sand bags were a hit with the fire crews. The wall went up in half the time and nobody got their fingers cut and bruised trying to fill narrow mouth conventional...

The surprising increase in methane concentrations millennia ago, identified in continental glacier studies, has puzzled researchers for a long time. According to a strong theory, this would have resulted from the commencement of rice cultivation in East Asia. However, a study conducted at the University of Helsinki's Department of Environmental Sciences and the Department of Geosciences and Geography shows that the massive expanse of the northern peatlands occurred around 5000 years ago,...

Peat has been a major component of substrates used in container plant production since the 1960s. Highly porous with the capacity to hold water, peat makes an ideal rooting and growing medium for potted plants. But harvesting peat (and draining valuable peatlands in the process) releases the carbon stored in peat into the atmosphere as carbon dioxide. And because peat plays an important role in wetland ecosystems"”peat bogs improve groundwater quality and are unique habitats for wild...

Global warming is speeding the release of carbon dioxide, a chief greenhouse gas, from underground peat in subarctic wetlands, Dutch research indicates. The research suggests rising temperatures are adding to the magnitude and velocity of global warming, Free University plant ecologist Ellen Dorrepaal and colleagues write in the journal Nature. Their research shows that raising temperatures about 1 degree Celsius accelerates total ecosystem respiration rates by as much as 60 percent, creating...

A new European study finds that climate change is accelerating the release of carbon dioxide (CO2) from sub-Arctic peatlands, stimulating a fierce cycle of global warming. Northern peatlands contain one-third of the Earth's soil-bound organic carbon, the equivalent of half the CO2 in the entire atmosphere.  An increase of just 1.8 degrees Fahrenheit (1.0 degree Celsius) over current average temperatures would more than double the amount of CO2 released from the peatlands, the study...
