Neste artigo serão apresentados e discutidos os dados sobre o controle da erosão, que os programas de manejo integrado do solo e da água em microbacias hidrográficas permitiram que fossem alcançados na Microbacia Rio do Campo, a partir de 1980. Para atingir este objetivo, foi feita uma estimativa da redução na perda de solo após a realização dos trabalhos, que serviu como parâmetro para mostrar o êxito desses programas ambientais. Em seguida, calculou-se o custo aproximado da erosão e da redução das perdas trazidas pelo manejo agronomicamente correto dos solos. Os resultados foram extremamente significativos revelando a necessidade de se manter e de se ampliar o uso dessa inovação, que em muito contribui para o desenvolvimento regional sustentável.In this paper data about erosion control will be presented and discussed. These data were achieved by integrated programs on soil and water conservation and management in watershed, which have been carried out in Rio do Campo since 1980. To achieve this objective a reduction estimate of soil lost was made after the work and this served as parameter to show the success of these environmental programs. Then, the approximated cost of erosion and the reduction of lost brought through correct agronomically management of soils were calculated. The results were extremely significant, and revealed a necessity to maintain and to enlarge the use of this innovation, which has contributed a lot to the sustainable regional development
