In this survey, it is assumed that the percentage of probable supply of environmental services in a watershed is exclusively associated to the typology of use and occupation in it. Relevance: Urban advancement, industrial development and unsustainable agricultural practices have altered the quantity and quality of environmental services provided by natural ecosystems, reflecting changes in land use. Results: 42.3% of the total area of the basin has conditions of use and occupation of the soil capable of providing component services of the four categories of services. The category of forest fragments is such that the provision of services occurs in greater quantity in the study basin, with a percentage of provision of 88.9%, followed by the category of green area (66.7%), agricultural activity and water resources (63% each) and exposed soil (15%). Contributions: The diagnosis of ecosystem and environmental services in the Ribeirão das Pedras basin may support Payment for Environmental Services programs and assist in the implementation of management standards for environmental conservation and recovery.
