Abstract

In recent decades there has been a large displacement of rural populations to urban areas. It is expected that by 2050, the world's urban population will be greater than 6.3 million people. This process often occurs with no planning and limits the protection of the biodiversity and ecosystems resources, which is particularly observed in tropical regions. The following urban sprawl generates the loss of forest cover and increases anthropogenic impacts on protected areas located where urbanities take place. Global agreements such as the 2030 Agenda proposed by the United Nations set a goal to stimulate a sustainable urban growth to mitigate impacted areas. Accordingly, the Brazilian Native Vegetation Protection Law and the National System of Conservation Units (SNUC) are in charge of regulating urban growth near forest areas. Protected by the SNUC, the Ecological Reserve of Ribeirão Preto (EERP, 154ha) is located in one of the main economic centers of São Paulo state's countryside, suffering from pressures of urban growth and an agriculture landscape dominated by sugar cane monoculture. Nevertheless, EERP hosts threatened species that develop a series of important ecosystem services, like the black capuchin monkey, Sapajus nigritus, and the black howler monkey, Alouatta caraya. The aim of this study is to evaluate scenarios of viability of both species, build upon demographic and populational information available on the literature, as well as the urban growth foreseen for the region. Through simulations on VORTEX software, we will evaluate these scenarios with diverse mitigation alternatives of the impacts caused by isolation and small population size. The results are important to the local conservation of these species and it will bring subsidies for the management of this Conservation Unit. Among the expected implications, we highlight the evaluation of the benefits that arise from the restauration of the protected areas localized in the EERP's buffer zone, that may improve the amount of habitat available for the primates and reduce the isolation of these populations.
