The objective of the study is to analyze the implementation of Sustainable Agricultural Practices in Brazilian Semi-arid (SAB) agricultural establishments. This is a relevant issue given the urgent need to control environmental degradation in rural areas of the region, largely caused by processes associated with inadequate soil management and the use of technologies that irreversibly compromise natural resources. The data worked were of secondary origin, extracted from the agricultural censuses of 2006 and 2017, published by IBGE. The geographical scale adopted in the study covered the 1262 municipalities of SAB. The analysis of 2017 data provided the basis for the current diagnosis of agricultural establishments regarding the implementation of sustainable agricultural practices, which were level planting, crop rotation, fallow or rest, protection and / or conservation of slopes. , riparian forest recovery, reforestation for spring protection, gully stabilization, forest management. As analysis methods were used descriptive statistics techniques, construction of aggregate index of adoption of sustainable agricultural practices and cluster analysis. The main results of the study showed that despite the growth in the adoption of some practices, the use of sustainable agricultural practices in the Brazilian Semiarid (SAB) is low and has a high heterogeneity among municipalities. Fallowing, crop rotation and level planting are the most adopted practices in SAB. Growth rate analysis showed that level planting and slope protection and / or conservation were the practices that most reduced in the period. On the other hand, the fallow obtained great growth, increasing about 90%. Crop rotation follows, with about a 60 percent increase in adoption. Regarding adoption rates, it was possible to notice that about 43% of SAB municipalities are at the lowest levels of implementation and that a large number of municipalities have retreated regarding the use of more environmentally conscious management.
