  • Abstract

    Estima-se que a turfeira da Bacia de Leyte Sab-a (LSBP), nas Filipinas, armazene enormes quantidades de estoques de carbono que podem influenciar a representação global do carbono da turfa tropical. No entanto, esse ecossistema único vem enfrentando ameaças que precisam ser estudadas, daí o estudo. As ameaças ao ecossistema foram analisadas usando a estrutura Driver-Pressão-Estado-Impacto-Resposta (DPSIR). A Entrevista com Informante-Chave (KII) e o QGIS também foram usados para avaliar os outros fatores do ecossistema. O principal fator determinante (D) foram fatores sociodemográficos, científicos e tecnológicos, sociopolíticos, valores religiosos e características biofísicas. Tornou-se claro que a pobreza da comunidade circundante e a demanda por aumento da produtividade da turfeira exerceram enorme pressão sobre o sistema. A degradação da turfeira começou décadas atrás devido à drenagem e à conversão agrícola, que é considerada a pressão significativa (P). O estado (S) dos estoques de carbono tem um valor monetário muito alto de US$ 1,4 bilhão para 3,5 ha de turfa. No entanto, as respostas da comunidade concentram-se na produtividade e não nos impactos da conservação das turfeiras (I). O mais alarmante é que a função das turfeiras como sumidouro de carbono passará a ser uma fonte que poderá gerar maiores emissões de carbono na atmosfera. Dado o estado atual da terra, com seu alto teor de carbono e águas de alto nível, mais ameaças e problemas surgirão no futuro se não forem abordados hoje. Portanto, como parte das respostas (R), a reformulação da gestão por meio de serviços paisagísticos pode equilibrar a produtividade e o armazenamento de carbono. A formulação de políticas de conservação seria útil, e a consideração do uso múltiplo das turfeiras é considerada a melhor opção para considerar tanto as turfeiras quanto a comunidade ao seu redor.
