Rainforest agriculture preserves bird biodiversity in India
Conservation of biodiversity and agriculture have long been considered conflicting interests. Numerous studies have shown that when agricultural replaces a forest, biodiversity greatly suffers. However a new study finds it doesn't have to be that way.

Eco-friendly shade-grown coffee buffers farmers against climate change
Shade-grown coffee plantations will be more resistant to climate change than conventional plantations, report researchers writing in the journal Bioscience. Shade grown coffee is already lauded for its environmental benefits including supporting high levels of biodiversity and requiring less fertilizers and pesticides.

Pre-Colombian Amazonians lived in sustainable 'urban' society
Researchers have uncovered new evidence to support the controversial theory that parts of the Amazon were home to dense "urban" settlements prior to the arrival of Europeans in the 15th century. The study is published this Friday in the journal Science. Conducting archeological excavations and aerial imagery across a number of sites in the Upper Xingu region of the Brazilian Amazon, a team of researchers led by Michael Heckenberger found evidence of a grid-like pattern of 150-acre towns and smaller villages, connected by complex road networks and arranged around large plazas where public rituals would take place. The authors argue that the discoveries indicate parts of the Amazon supported "urban" societies based around agriculture, forest management, and fish farming.

Defaunation, like deforestation, threatens global biodiversity
Loss of wildlife is a subtle but growing threat to tropical forests, says a leading plant ecologist from Stanford University. Speaking in an interview with mongabay.com, Dr. Rodolfo Dirzo says that the disappearance of wildlife due to overexploitation, fragmentation, and habitat degradation is causing ecological changes in some of the world's most biodiverse tropical forests. He ranks defaunation — as he terms the ongoing biological impoverishment of forests — as one of the world's most significant global changes, on par with environmental changes like global warming, deforestation, and shifts in the nitrogen cycle.

Carbon credits for forest conservation concept faces challenges
While environmentalists, scientists, development exports, and policymakers across the political spectrum are ethusiastic about the idea of offsetting carbon emissions by preventing deforestation (a concept known as "avoided deforestation" or Reduced Emissions from Deforestation and Degradation (REDD)), the concept still faces many challenges, especially in implementation.
