RESUMOEste trabalho teve como objetivo comparar cenários de ocupação urbana e seus efeitos no ciclo hidrológico da Bacia do Mineirinho. Buscou-se avaliar os riscos de enchentes causados pelo aumento das áreas de impermeabilização que tem ocorrido com a implantação do novo Campus da USP, São Carlos, SP.

Socio-economic aspects can limit the expansion of ecological restoration. One alternative to address this question is the development of restoration models that generate income to farmers in addition to the benefits from conservation itself. We designed and implemented the initiative "Sustenta A Mata," a project developed by The Nature Conservancy and supported by the Brazilian Development Bank (BNDES), to generate economic and social benefits for the communities involved. This study aims to analyze the financial viability of the enrichment restoration initiative in forest remnants based on a 30 year projection. The project was implemented on 17 hectares of land that included timber and non-timber species with a focus on the Juçara Palm (Euterpe edulis Mart.) for the production of fruit. Estimated earnings come from both the production of timber and juçara fruits. We considered input, equipment and labor costs for implementation, maintenance, and harvesting. For the economic analysis we used the following criteria: Net Present Value (NPV); Return on Investment (ROI); Benefit/Cost Ratio (B/C), and Payback. From these indicators the following values were obtained as results: US$4,040.80 of NPV, 13 percent of ROI, 1.59 of B/C and a 13-year Payback. These positive results for the aforementioned indicators reveal that the use of the enrichment restoration initiatives utilized in this project may contribute to the economic viability of the endeavor, contributing to a greater sustainability in rural areas.
