Due to landscape fragmentation, Brazil's rainforests are releasing more carbon dioxide
2014-10-07 17:46:00| Climate Ark Climate Change & Global Warming Newsfeed
ScienceDaily: Because of the deforestation of tropical rainforests in Brazil, significantly more carbon has been lost than was previously assumed. As scientists of the Hemholtz Centre for Environmental Research (UFZ) write in the scientific journal Nature Communications, the effect of the degradation has been underestimated in fragmented forest areas, since it was hitherto not possible to calculate the loss of the biomass at the forest edges and the higher emission of carbon dioxide. The UFZ scientists have now...

UN members pledge to restore woodland and safeguard rainforests
2014-09-07 01:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Independent: Since the birth of agriculture thousands of years ago, humans have cut down the world's forests to grow food and expand their population. But now experts believe the end of our "war on trees" is in sight amid what some are calling a new "green revolution" finally breaking the causal link between growing numbers of people and falling numbers of trees. At a United Nations meeting later this month, countries are expected to pledge to restore between 10 and 15 million hectares of woodland and to...

World's rainforests could be mapped in 3D at high resolution by 2020 for under $250M

Mongabay: Mapping the world's tropical forests with a fleet of airplanes outfitted with advanced LiDAR could rapidly and accurately assess global forest carbon stocks for a fraction of the cost of a typical Earth observation satellite mission - and far less than field-based sampling - argues a new paper published in Carbon Balance and Management. The commentary, authored by a group of prominent scientists from several institutions, reviews recent progress in applying laser ranging technology (LiDAR) to...

How Palm Oil Ravages Rainforests, Endangers Wildlife & Destroys Communities
2014-07-18 16:16:00| Climate Ark Climate Change & Global Warming Newsfeed
EcoWatch: Agriculture plays a massive role in todays global economy. Its easy to not realize that your salads fresh tomatoes are likely flown in from the Netherlands, its asparagus is picked by a Peruvian farmer and the dressing has palm oil harvested in Indonesia. Our complicity in an agricultural system that ships food products across the world via air, land and sea becomes a political decision, one that impacts the environment on a global scale. And palm oil, a popular ingredient in nearly 75 percent...

30% Borneo rainforests destroyed since 1973
2014-07-16 23:09:00| Climate Ark Climate Change & Global Warming Newsfeed
Mongabay: More than 30 percent of Borneo's rainforests have been destroyed over the past forty years due to fires, industrial logging, and the spread of plantations, finds a new study that provides the most comprehensive analysis of the island's forest cover to date. The research, published in the open-access journal PLOS ONE, shows that just over a quarter of Borneo's lowland forests remain intact. The study, which involved an international team of scientists led by David Gaveau and Erik Meijaard, is based...
