SUMMARY:

The objective of this study is to comprehend the transition process of convetional systems of agricultural production for the Agro Forestry Systems (SAFs), in the property of familiar farmers of the municipality of Tomé-Açu, Pará. The collection of the data occured in the local SAFs. The research was organized in three chapters. The first chapter approaches the process of transition of the convetional system of the land  to the use of the SAFs. For this research were utilized qualitatives and quantitatives types of approach, the method of the gathering of data was done with a structured interview guided via the tool ODK Collect. The results show that: The transition of the conventional system for the SAF in the properties of the local farmers occured in the areas of monoculture of the black pepper to diversify the products that generate income along the year and give environmental comfort to the farmer; It was identified various sequential processes of change from the conventional system to the SAF. 66,7% of the properties in the three categories (pasture, black pepper and farm) presented a transition before the application of the SAF and 3,3 % of the properties showed four types of use before the application of the SAF; The diversity of species living in the zone of the SAFs favor the food safety and the income of the families, then contributing in the sustainable development strategy in the municipality. The second chapter evaluates the space-time dynamic, in the years of 2010 and 2020 of the transition of the conventional system to the SAF. The methodology was based in the elaboration of maps of the Kernel density, thematic maps and the application of semi-structured questionaires. The results show that: the space-time analysis turned out that alterations of the landscape, originally composed of pasture, farm and black pepper were substituted gradually for SAFs areas, the Kernel density analyzed too the behavior of the SAFs density, the SAFs changed the scenario of the properties, increasing the areas of legal reserve. The applicability of the geotechnology tools turns out to be important to monitor the areas occupied with the SAF. The third chapter looks to evaluate the SAFs from processes of transition of different productive systems via the indicators of sustainability using the methodology proposed by Altieri & Nicholls (2002). The results shows that: The area that the conventional systems presented the lower medium value of indicators that suggest the necessity of proper handling to prevent environmental issues in those areas, the higher the medium values of the indicators were obtained in areas of capoeira and SAFs, standing out the role these areas have in recovering the productive potential of agrosystems.
