Ana Rodrigues of the Centre for Functional and Evolutionary Ecology in Montpellier, France, and colleagues say the Brazilian government needs to find ways of hoisting Amazon communities out of poverty without relying on deforestation.
In the study, the researchers used data on life expectancy, and levels of income and education from 286 municipalities in the Amazon.
They grouped the communities depending on how much they had deforested their land, ranging from those that lived in pristine or near-pristine forest to those that had completely deforested their village area. In the middle were communities located at the “frontier” of deforestation, where cutting, clearing and logging activities were on-going.
Grouping the communities in this way meant the researchers were able to compare the income, life expectancy and education levels according to how extensively the regions were deforested.
Short-lived boom
“We found that the level of development in a region that has been through deforestation is indistinguishable from in a region prior to deforestation,” says Robert Ewers of Imperial College London.
The data showed that although welfare rapidly improves during deforestation, this socio-economic boom is short-lived. Moreover, a region that is being deforested attracts migrants eager to make a quick buck or set up a farm. Not all of these leave once the forest is cut down, so once the wave of deforestation has passed through a community, it is more populated than before.
