“PopulaçÔes habitam a regiĂŁo amazĂŽnica hĂĄ milhares de anos, mas o avanço de elementos da vida moderna estĂĄ pondo em risco a sustentabilidade desses povos e do ecossistema onde vivem. Essa Ă© a conclusĂŁo de um estudo elaborado pela equipe do biĂłlogo portuguĂȘs JosĂ© Fragoso, da Universidade Stanford, nos EUA.” “ — Os resultados da pesquisa mostram que apenas nĂŁo invadir ĂĄreas indĂ­genas nĂŁo Ă© suficiente — diz Fragoso. — O que acontece no entorno das reservas tem grande impacto no interior.”

Stanford University publishes news piece regarding our new publication.

Stanford University reports on how our computer model simulating sustainability sheds light on how modern interventions can affect tropical forests and indigenous peoples. Our computer simulation shows that carefully designing government interactions with rural indigenous people is critical for protecting the sustainability of people, wildlife and the land.

New Publication: Socio–environmental sustainability of indigenous lands: simulating coupled human–natural systems in the Amazon

Our latest publication is out in Frontiers in Ecology and The Environment. We examine the socio-environmental sustainability of protected areas inhabited by indigenous and rural peoples and describe how socio-ecological change and development (e.g., forest clear-cutting outside indigenous areas, religious conversion, improved child mortality rates and introduction of resources from outside) outside these areas influences the sustainability of biodiversity, forest cover, and people inside. There are some surprising results so read the publication!

Research collaborators Takuya Iwamura, Eric Lambin, Kirsten Silvius, Jeffrey B Luzar, and JosĂ© Fragoso have a new paper in press. The publication examines the resiliency and sustainability of biodiversity, human livelihoods and forest cover within Amazonian indigenous lands under various future development scenarios. The paper is scheduled for publication in the February 2016 issue of the journal “Frontiers in Ecology and the Environment”.

“A fine line: new computer program predicts when human impact becomes too much”

We have completed a major work describing the sustainability of hunting, farming (land use) and local livelihoods in the tropics. We devised an agent based computer simulation model and explored the relationships between the above mentioned elements to consider what the future may hold for tropical forest biota, ecosystems and peoples.

Stanford University, Mongabay and others published news reports about the work. You can view two here: http://news.stanford.edu/news/2014/june/amazon-sustainability-model-061314.html

“Assessing Carbon Stock Value of Forests is Tricky Business”

Mongabay’s Sanhya Sekar  wrote two articles concerning the Fragoso Group’s work with indigenous people’s field measurements of tropical forest carbon stocks.  Sekar writes  “With financial incentives encouraging maintenance of carbon stocks and the increased popularity of carbon trading between countries, a forest has become economically a lot more than a clump of trees that supplements livelihoods. A forest now has an intrinsic value by just existing, a value that can be measured in economic terms.”
