Bolivia's aggressive agricultural development plans threaten forests
2015-06-08 22:43:00| Climate Ark Climate Change & Global Warming Newsfeed
Mongabay: Bolivia's government, supported by some small and most large producers, pushes to expand agricultural lands at the expense of the nation's environment. In April 2015, small-scale Bolivian farmers who painstakingly work the land as their ancestors did clearing small plots, planting and waiting for rain gathered for a summit with stakeholders from a very different part of the agricultural sector: commercial farmers who oversee vast farms and watch international exchange markets just as closely...

First-of-its-kind mapping technique sheds new light tropical forests
2015-05-29 19:54:00| Climate Ark Climate Change & Global Warming Newsfeed
Mongabay: Scientists at the Woods Hole Research Center in Massachusetts have developed vegetation height maps for the entire tropics at very fine spatial scales. These first-of its-kind high resolution maps can help researchers estimate forest cover, monitor biodiversity and wildlife habitats, and manage and monitor timber, according to a recent press release by WHRC. The WHRC researchers, led by senior scientist Josef Kellndorfer, combined two active remote sensing systems radar and lidar to create...

How global warming make forests shorter and scrubbier
2015-05-20 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Christian Science Monitor: As global warming progresses, look for increasing expanses of majestic forests worldwide to become short and scrubby. That is the implication of a new study that applies a well-established principle of fluid flow to the inner workings of vegetation. The analysis doesn't attempt to specify timing or specific locations where such shifts in vegetation would occur. Instead, it uses the principle known as Darcy's law to explore the general types of vegetation most likely and least likely to survive...

New mapping project uncovers road networks in Perus primary forests
2015-05-13 23:41:00| Climate Ark Climate Change & Global Warming Newsfeed
Mongabay: Roads spread out like multi-fingered tendrils, eating into the surrounding forests of Cordillera Azul National Park, in the Department of Loreto in Peru. What is their purpose? Are they being built legally? If so, are they remaining within the specifications of their permits, or are they overstepping their bounds? A team of researchers has taken a first, important step in answering these questions by determining the roads' locations and extent using images and data collected by satellites. The...

Brazilian beef industry moves reduce its destruction rain forests
2015-05-12 17:02:00| Climate Ark Climate Change & Global Warming Newsfeed
ScienceDaily: Expansion of cattle pastures has led to the destruction of huge swaths of rain forest in Brazil, home to the world's largest herd of commercial beef cattle. But a new study led by the University of Wisconsin-Madison's Holly Gibbs shows that market-driven "zero deforestation agreements" have dramatically influenced the behavior of ranchers and the slaughterhouses to which they sell. Publishing in the journal Conservation Letters, the research team -- including other UW-Madison scientists, the National...
