In the Amazon, diseases follow forest transformation

,
A Brazilian study of more than one million cases of malaria, dengue, Chagas disease and leishmaniasis reveals how diseases cluster in distinct “health landscapes” shaped by different land-use: from forest communities to large-scale agricultural systems

New database reveals the climate cost of degradation in tropical forests

,
Researchers have synthesized nearly four decades of data, producing one of the most comprehensive assessments ever compiled of forest carbon dynamics following disturbances and during subsequent regeneration

When El Niño-related drought strikes, Amazon forest turns to chemical self-defense

,
A study shows how the rainforest altered its volatile compound emissions during the most severe drought ever recorded in the Amazon, triggering a mechanism with implications for the atmosphere
Planting trees on pastures is an effective strategy for protecting biodiversity, but not as much as preserving natural forests. Photo: Onderwijsgek Attribution-ShareAlike 3.0 Unported CC BY-SA 3.0 DeedOnderwijsgek Attribution-ShareAlike 3.0 Unported CC BY-SA 3.0 Deed

Planting trees in pastures increases biodiversity by 44 per cent

,
In developing countries, livestock farming is a means of livelihood for one billion farmers, but the growing need for space for pastures is driving deforestation. A German study suggests how to reconcile economic development and biodiversity

Beyond the Amazon: a forgotten carbon reserve in Brazil’s wetlands

,
In the Brazilian savanna, wetlands store enormous amounts of carbon, but they are threatened by climate change and agricultural expansion. Moreover, conservation policies, which focus almost exclusively on forests, tend to ignore them
The construction of new roads is a particularly significant sign of deforestation. However, many of them are difficult to identify.

A map of future roads helps fight deforestation

,
A team of Australian researchers managed to develop a deforestation risk index based on the probability that an area may be affected by new road construction
59% of global deforestation is caused by meat production and 33% by soy production, both occuring in the Amazon. Photo: Ben Lamb Attribution-NonCommercial-ShareAlike 2.0 Generic CC BY-NC-SA 2.0 DeedBen Lamb Attribution-NonCommercial-ShareAlike 2.0 Generic CC BY-NC-SA 2.0 Deed

Meat and soybean (plus coffee) are driving deforestation in the Amazon

,
The latest WWF report identifies the main factors behind the ongoing phenomenon in the Amazon. Meat and soy top the list in terms of impact, ahead of cocoa, palm oil, and coffee
