RESUMO:

The welfare and survival of the human being has always depended on natural resources. With the loss of natural ecosystems in the world due to changes in land use, the services provided by these environments are gaining more emphasis in the scientific environment. Several initiatives endeavor to study interactions between human populations and ecosystems, using tools and methodologies to analyze scenarios. However, they still have limitations regarding multi-scale approaches and definition of economic values to encourage the maintenance of areas intended for the provision of ecosystem services. Thus, our work has focused on the importance of Amazonia as a service provider for society, especially the Amazon-Cerrado transition area, due to its occupation history, which can bring us relevant insights and lessons on the reflexes of our policies of territorial occupation. We study the Amazon-Cerrado transition region at different scales and find that changes in land use have been affecting the supply of ecosystem services, especially affecting the poorest and most dependent on the local scale. Our results show that the model advocated by the territorial occupation policies is built on a large scale and has deficiencies for finer scales of analysis, where a great wealth of interactions between humans and nature are observed. We did not identify evidence that such a model promotes a better distribution of wealth and, therefore, poverty reduction in the region. On the contrary, we find locally that it generally promotes the concentration of wealth and the loss of ecosystem services that are important for maintaining the quality of life of the poor. In our scenario, extensive agriculture and livestock predominate, and the activities are responsible for such results, but payment for ecosystem services can be financially attractive for a change in rural income generation. We also noted in our study that Indigenous Lands play an important role in providing ecosystem services in the region, especially maintaining water for urban supplies and productive activities.
