The challenge of balancing food production, ecosystem services (ESs) and biodiversity conservation evidences the disruption of the present agri-food system. This demands a social-ecological system transformation. For this, the replacement of conventional agricultural practices to agroecological ones has been suggested, since these practices could provide ESs provision, which agriculture and human life are dependent on, and a permeable matrix, which is indispensable for biodiversity conservation. However, the food production activity also needs to afford small farmers livelihood, otherwise, they will not be interested in taking part of this transition. In view of this, the present dissertation has the objective of analyzing agroecology as a proposal to provide farmers livelihood, generate ESs and contribute for biodiversity conservation, integrally. In order to reach the objective proposed, we selected the case study of Santa Rosa de Lima (SRL), located in Santa Catarina (SC) state, which is inserted in area of Atlantic Forest (AF), in Southern Brazil. This municipality has many dairy farmers associated with AF. AF is globally recognized as a priority biome for biodiversity conservation, due to its rich biodiversity and current level of degradation. Furthermore, the biome provides diverse ESs. Dairy activity has been extensively referred as a major driver of AF deforestation, on other hand, dairy activity is of relevance for the state economy and farmers livelihood. Due to the referred, it was brought to SC a potential agroecological and sustainable intensification (SI) dairy system, the management intensive grazing (MIG) system. The hypothesis was that the implementation of this system has potential to increase dairy profitability, reduce reliance on off-farm inputs, provide ESs and decrease pressure on remaining forest. Additionally, by increasing stocking rate and milk yields, farmers may be able to retire land from production to conservation without suffering an economic loss. To analyze the results of MIG implementation in SRL, as an agroeological system with potential to balance economic and ecological goals, we compared social, ecological and economic data of farmers applying MIG and farmers applying conventional systems. These data were collected through farmers interview and an accounting project conducted in the city during one year. As first research result, we found that MIG is still in process to become considered an agroecological system. Therefore, we analyzed this process of transformation through the lenses of social theories for social-ecological system transformation. In summary, our results has showed that MIG is more profitable than conventional systems, have increased land efficiency and showed signs of environmental improvements, however, still needs progresses to become an agroecological and sustainable intensification system. This process of transition has already started in SRL, since, among the mentioned and other evidences, MIG has gradually reduced the use of environmentally damaging inputs and farmers has showed to be more prone to meet environmental law. Our results also indicate social learning as indispensable, and financial capital as necessary to foment the process of transformation. To introduce both in the process, Participatory Processes and Payment for Ecosystem Services are advocated as suitable tools.
