چکیده

The Brazilian Amazon frontier shows how remarkable leadership can work towards increased agricultural productivity and environmental sustainability without new greenhouse gas emissions. This is due to initiatives among various stakeholders, including national and state government and agents, farmers, consumers, funding agencies and non-governmental organizations. Change has come both from bottom-up and top-down actions of these stakeholders, providing leadership, financing and monitoring to foster environmental sustainability and agricultural growth. Goals to reduce greenhouse gas emissions from land-cover and land-use change in Brazil are being achieved through a multi-tiered approach that includes policies to reduce deforestation and initiatives for forest restoration, as well as increased and diversified agricultural production, intensified ranching and innovations in agricultural management. Here, we address opportunities for the Brazilian Amazon in working towards low-carbon rural development and environmentally sustainable landscapes.

Ontology-Based Modeling of Land Change Trajectories in the Brazilian Amazon

Tropical deforestation is an example of geochange with massive impacts to the environment locally and globally. In the Brazilian Amazon deforestation has prevailed owing mostly to private investments in agricultural expansion, associated with large-scale cattle ranching, smallscale subsistence farming and soybeans expansion. Data on deforestation have been relied mostly on satellite remote sens...

Greenhouse gas emissions from alternative futures of deforestation and agricultural management in the southern Amazon.

The Brazilian Amazon is one of the most rapidly developing agricultural areas in the world and represents a potentially large future source of greenhouse gases from land clearing and subsequent agricultural management. In an integrated approach, we estimate the greenhouse gas dynamics of natural ecosystems and agricultural ecosystems after clearing in the context of a future climate. We examine...
