Six Tropical Forest Countries Qualify for Forest Carbon Partnership Facility REDD+ Grants

Six countries qualify for forest carbon partnershipThe key facilitator in multilateral, international efforts to halt deforestation, forest degradation and resulting greenhouse gas emissions, the Forest Carbon Partnership Facility (FCPF) recently announced some $23 million in new grant funding for six additional REDD+ Country Participants.

Chile, Honduras, Papua New Guinea, Suriname, Thailand and Vanuatu all submitted national REDD+ Readiness Plans to the FCPF Particpants Committee at the sixth meeting of the Carbon Fund Participants in Washington D.C. in late March. This paves the way for them to receive $3.8 million each “to support activities such as developing national REDD+ strategies; developing reference emission levels; designing forest monitoring systems; and setting up REDD+ national management arrangements, including proper safeguards.”

Eighty percent of above-ground and 40 percent of underground terrestrial carbon is found in the world’s diminishing forests. Rising populations and business-as-usual economic policies and commercial activities threaten what remains of worldwide forest cover and the myriad ecosystems services, as well as intrinsic value, they provide to human populations and society, however.  Read More→

Forest Carbon Release from Pine Beetle Infestation Not as Severe as Expected

Forests devastated by pine beetle infestation may not release the huge flux of carbon as once fearedAs large swaths of western forests in North America succumb to pine beetle infestation, due in part to warming winters, preliminary studies show that the dead, decaying trees are not releasing the huge flux of CO2 previously feared by scientists. According to a study just released in the journal Ecology Lettersdespite the billions of trees killed in the pine beetle infestation ranging from Mexico to Alaska, the expected spike in forest carbon release into the atmosphere has not occurred – at least in the Colorado forest where the initial study took place.

“A couple of the early ideas were that, one, it was just going to have this big release of carbon because all of the dead stuff would just decay really quickly, and the other idea was that it would all burn. Neither of these seems to have happened yet,” said ecologist David Moore of the University of Arizona’s College of Agriculture and Life Sciences and lead author on the study. “The general expectation we had was that when trees die on a large scale, it would lead to a big pulse of carbon into the atmosphere through microorganisms metabolizing all that dead wood.

USDA Reports on Climate Change Effects, Adaptation for Agriculture, Forests

forest-after-fire-sun-valleyThe U.S. Department of Agriculture (USDA) on February 5 released “two comprehensive reports that synthesize the scientific literature on climate change effects and adaptation strategies for U.S. agriculture and forests.”

The effects of climate change will be profound and far-reaching, according to the two reports, which drew on more than 1,000 peer-reviewed studies carried out by scientists in federal service, universities, non-governmental organizations, industry, tribal lands and the private sector.

“These reports present the challenges that U.S. agriculture and forests will face in this century from global climate change,” William Hohenstein, director of the Climate Change Program Office in USDA’s Office of the Chief Economist, said in a press release. “They give us a framework for understanding the implications of climate change, in order to meet our future demands for food, feed, fiber, and fuel.” Read More→

EarthTalk: Global Warming and Deforestation

Deforestation is a major contributor to anthropogenic carbon emissionsEarthTalk® is a weekly environmental column made available to our readers from the editors of E/The Environmental Magazine

Dear EarthTalk: Is it true that cutting and burning trees adds more global warming pollution to the atmosphere than all the cars and trucks in the world combined?     – Mitchell Vale, Houston, TX

By most accounts, deforestation in tropical rainforests adds more carbon dioxide to the atmosphere than the sum total of cars and trucks on the world’s roads. According to the World Carfree Network (WCN), cars and trucks account for about 14 percent of global carbon emissions, while most analysts attribute upwards of 15 percent to deforestation.
