Protecting the Amazon with protected areas.
This article addresses climate-tipping points in the Amazon Basin resulting from deforestation. It applies a regional climate model to assess whether the system of protected areas in Brazil is able to avoid such tipping points, with massive conversion to semiarid vegetation, particularly along the south and southeastern margins of the basin. The regional climate model produces spatially distrib...
متن کاملRole of Brazilian Amazon protected areas in climate change mitigation.
Protected areas (PAs) now shelter 54% of the remaining forests of the Brazilian Amazon and contain 56% of its forest carbon. However, the role of these PAs in reducing carbon fluxes to the atmosphere from deforestation and their associated costs are still uncertain. To fill this gap, we analyzed the effect of each of 595 Brazilian Amazon PAs on deforestation using a metric that accounts for dif...
متن کاملProtected areas – protected species?
Wild life: The elusive fosa (Cryptoprocta ferox) is the top predator in the dry deciduous forests of Madagascar, but very little was known about its biology until the 1990s. The presence of volunteer groups studying its role in the forest’s ecology has also helped to protect its habitat. (Photo: Earthwatch/ Luke Dollar.) The world’s latest national park has just been created in the east of Russ...
متن کاملIllegal use of natural resources in federal protected areas of the Brazilian Amazon
BACKGROUND The Brazilian Amazon is the world's largest rainforest regions and plays a key role in biodiversity conservation as well as climate adaptation and mitigation. The government has created a network of protected areas (PAs) to ensure long-term conservation of the region. However, despite the importance of and positive advances in the establishment of PAs, natural resource depletion in t...
متن کاملEffects of Protected Areas on Forest Cover Change and Local Communities: Evidence from the Peruvian Amazon
Protected areas are a cornerstone of forest conservation in developing countries. Yet we know little about their effects on forest cover change or the socioeconomic status of local communities, and even less about the relationship between these effects. This paper assesses whether “win-win” scenarios are possible—that is, whether protected areas can both stem forest cover change and alleviate p...
