Serviços ecossistêmicos urbanos: fixação de carbono nas áreas de preservação permanente de Campinas-SP

Abstract

Este trabalho apresenta o potencial de fixacao de carbono e provisao de demais servicos ecossistemicos das Areas de Preservacao Permanente ao longo dos cursos d’agua do municipio de Campinas-SP. Ainda, calculou-se o custo associado ao servico de fixacao de carbono e o quanto o municipio se beneficiaria ao criar um mercado para os creditos de carbono gerados nos projetos de reflorestamento destas areas. Foi demonstrado que a comercializacao dos creditos cobriria ate 46% dos custos de implantacao dos projetos. Alem da fixacao de carbono, a recuperacao das APPs ao longo de cursos d’agua proporciona servicos ecossistemicos adicionais ao municipio, e que se contemplados na analise custo-beneficio dos projetos de reflorestamento representam a maior porcao dos beneficios totais. Portanto, a inclusao dos beneficios gerados pelos servicos ecossistemicos adicionais mostrou-se fundamental para tornar a recuperacao das APPs economicamente viavel.

This work presents the potential of carbon sequestration and provision of other ecosystem services in the Permanent Preservation Areas along the watercourses of the city of Campinas-SP. Also, the cost associated with the carbon sequestration service was calculated and how much the municipality would benefit from creating a market for the carbon credits generated in the reforestation projects in these areas. It was shown that the commercialization of credits would cover up to 46% of the project implementation costs. In addition to carbon sequestration, the recovery of PPAs along watercourses provides additional ecosystem services to the municipality, which if contemplated in the cost-benefit analysis of reforestation projects represent the largest portion of the total benefits. Therefore, the inclusion of the benefits generated by the additional ecosystem services has proved to be fundamental to make the recovery of PPAs economically viable.
