The main objective of this research is to comprehend the social processes leading to spontaneously-formed assentamentos, and to assess associated impacts on Amazonian deforestation. Three hypotheses were tested about spontaneous DALR and developed with the support of anecdotal field evidence. Two were related to factors driving the appearance of these settlements, and one related to the environmental impacts on the landscape. More specifically, the first one states that spontaneous DALR occurs on unclaimed public lands beyond the frontier, given the low land value of primary forest areas. The second hypothesizes that spontaneous DALR is a consequence of early land reform policies that stimulated in-migration to the region as well as from demographic household life cycle. The last hypothesis states that spontaneous DALR increases deforestation and fragmentation. Also, I argue that the underlying/proximate causation (UPC) framework of land use and land cover change to date has tended to provide considerable generalization across highly aggregate factors, which complicates applications to specific processes of possible interest. To achieve my goals, I conducted key informant interviews with community leaders and government officials about settlement location selection process, and undertook a case study of five fully- or near fully-formed settlements. In addition, I conducted a remote sensing analysis of deforestation and fragmentation occurring in nine assentamentos found in the Transamazon Highway region with the objective of evaluating their impacts on the landscape.
