Strictly protected areas such as national parks and biological reserves have been more effective at reducing deforestation in the Amazon rainforest than so-called sustainable-use areas that allow for controlled resource extraction, CHANS-Net scientists and their colleagues have found.

It's no secret that China is faced with some of the world's worst pollution. Until now, however, information on the magnitude, scope and impacts of a major contributor to that pollution -- human-caused nitrogen emissions -- was lacking.

Hurricane Sandy was a fearsome reminder that coastal communities are highly vulnerable to extreme weather events and environmental variability, and that vulnerability is only expected to increase with climate change.

For social animals such as schooling fish, the loss of their numbers to human activity could eventually threaten entire populations, according to research led by a CHANS-Net scientist that shows such animals rely heavily on grouping to effectively navigate their environment.

In Missouri forests, dense thickets of invasive honeysuckle decrease the light available to other plants, hog the attention of pollinators and offer nutrient-stingy berries to migrating birds. They also release toxins that decrease the germination of nearby native plants. Why, then, do studies of invasive species come to different conclusions about their effects and lead some organizations to suggest we accept their presence?

Hydraulically fractured natural gas wells are producing less wastewater per unit of gas recovered than conventional wells would. But the scale of fracking operations in the Marcellus shale region is so vast that the wastewater it produces threatens to overwhelm the region's wastewater disposal capacity, according to new analysis by a CHANS-Net researcher at Duke and a colleague at Kent State.

How do people adapt to forest fires?

That question underlies the interdisciplinary Forest People Fire (FPF) project and is the focus of the next U.S. Forest Service Landscape Science webinar on Jan. 22 at 1 p.m. EST.

CHANS-Net members Jose Manuel Fragoso, Jeff Luzar, and Kirsten Silvius have two new papers in Human Ecology. Both examine the interactions between varous Western religions and the religions of indigenous peoples. They also examine the implications of changes in belief systems because of interactions on biodiversity.

Over past decades, many areas of the forested Amazon basin have become a patchwork of farms, pastures and second-growth forest as people have moved in and cleared land -- but now many are moving out, in search of economic opportunities in newly booming Amazonian cities. The resulting depopulation of rural areas, along with spreading road networks and increased drought are causing more and bigger fires to ravage vast stretches, say researchers in a new study.
