SUMMARY:

The objective of this case study was to discriminate the main factors that influence the choices of land use and soil management, shaping the decision making of family farmers in the Zé Pureza-RJ agrarian reform settlement project. In order to achieve this objective, there were evaluated the main parameters that shaped the rationality of land use and land management choices of family farmers, and the physical and social space in which they are inserted was characterized. Initially, interviews were conducted based on scripts with socioeconomic items and another with types of exploration and land management adopted, in addition to characterization of production units. Based on the answers from interviews with 20 families in Zé Pureza settlement, a structured questionnaire on land use and management was elaborated. This questionnaire was applied through interviews with each family, and the objective answers supported the multivariate analysis. For the refinement of maps of the use and environmental characterization of the settlements, obtained by satellite images, field surveys were carried out, concomitant to the interviews. Based on the history of land use and management, representative areas of main types of usage were selected for assessment of soil quality using some atrributes (pH, Ca+Mg, K, P, Al, Al+H, N, C, Total Organic Carbon - TOC, Particulate Organic Carbon – POC, mineral-associated Organic Carbon - MinOC and Light Organic Matter- MOL). As a result, it was found that the creation of the Zé Pureza settlement caused an abrupt change in the land coverage, from an area with homogeneous pasture to a mosaic of usages, including crops and pasture. The choices of land use and agricultural practices adopted by farmers, which configure this mosaic, do not portray their knowledge and perceptions, but their resource limitations. The low use of fertilizers, agrochemicals, the time and place of harrowing, the division of pastures, the absence of production registers, are not configured as choices, but due to the condition imposed on them. Even, sometimes, conflicting with the perception / knowledge that these farmers have of the environment and their own practices. The current configuration of the choices of farmers in the Zé Pureza settlement is shaped by structural issues. Low schooling, lack of technical assistance and limited financial resources foster a cycle that leads to less and less favorable conditions for assertive choices. A proposal to change the farmers' way of production will have greater adherence if it results in greater financial stability and reduction in need of family workforce. The application of methods of Multiple Correspondence Analysis, followed by hierarchical Cluster, corroborated a pattern captured by the descriptive statistics of the data from the questionnaires. The absence of very distinct clusters and the low variance captured by the models indicate that structural factors are conditioning farmers' choices and perceptions. This suggests that structural limiting factors generate a dispersed behavior of farmers (objects), as they respond to individual opportunities. A favorable scenario for the adoption and long-term maintenance of soil conservation practices implies in reducing the vulnerability of agro-ecosystems reproduction strategies by expanding the autonomy of these agro-ecosystems.
