Key words: Bioenergy, Land use change, Land cover change, Planted forest, Native vegetation, Environmental impacts
Brazil holds a large share of the world’s remaining natural forests, about one-third of the existing rainforest and most of the Amazon rainforest. Currently, approximately two-third of the Brazilian territory is covered with natural vegetation. Over the coming years, due to population growth, economic development, diet shift, and increased demand for biomass-based energy, the ongoing agriculture expansion and intensification, taking place in Brazil, is expected to continue and intensify. Such an expansion will most certainly contribute to developing remote regions of Brazil, creating business opportunities and generating new jobs in rural areas. However, this development is expected to have various impacts on these rural areas, with various repercussions in the form of environmental and socioeconomic impacts. Agricultural expansion over native vegetation may threat natural ecosystems in various ways, such as losses of natural habitats and biodiversity, changes in the carbon dioxide exchange between biosphere and atmosphere and changes in water quantity and quality. Therefore, in order to understand the land use changes as well as the complexity of its environmental and socio-economic impacts, it is crucial to elaborate, test and validate robust land use change models, which can produce strategic information to support decision making. This study focus on the socio-economic and environmental effects caused by the expansion of planted forest in Brazil.
This research project aims primarily at enriching the knowledge related to land use changes caused by agricultural expansion for planted forest, employing land use expansion models and scenarios analysis. Furthermore, in the scope of this research project, modeling methodologies will be developed and adapted to assess environmental and socio-economic effects of planted forest expansion in Brazil. The results can potentially support the adoption of more sustainable pathways of agriculture expansion and guide the strategies to mitigate negative environmental and socio-economic impacts, while enhancing the gains from this development.
The project is implemented in close cooperation with the Agriculture College of the University of São Paulo (ESALQ/USP), with Prof. Gerd Sparovek, and Chalmers University of Technology, Energy and Environment Department (the Physical Resource Theory Division) with Prof. Göran Berndes
