摘要
Trade-offs in ecosystem services (ES) have received increasing attention because provisioning services often come at the expense of biodiversity loss. When land-use patterns are not maximally efficient relative to productivity, provisioning services, such as crop production, can often be increased without losing biodiversity. The Atlantic Forest (AF) encompasses dense, mixed, and seasonal forests and has high levels of endemism and anthropogenic threat. We examined trade-offs between biodiversity and crop production in the AF to provide insights into land-use management decisions. We developed a biodiversity metric that combines information on tree species richness, evolutionary distinctiveness, and rarity at the local level. We examined the extent to which the nature of ES trade-offs differ among the 3 forest types. We assessed how annual deforestation rates and land management practices affect biodiversity and agricultural revenues. Finally, we tested whether it is possible to achieve the same total regional revenue without reducing biodiversity by improving local management practices. The 3 forest types had similar patterns in ES trade-offs, although within mixed forest patterns differed. Biodiversity appeared to be more sensitive to land-use change than crop revenues. Certain crops yielded up to 10 times higher values in some sites. Enhanced crop productivity may increase revenues without reducing biodiversity. Our results showed that to enhance human well-being without further conversion of AF, maximizing crop productivity is needed . Increasing efficiency of management outcomes by maintaining higher biodiversity and increasing provisioning services depends on knowledge of forest type, the comparative advantage of planting crops in the best places, and preserving species in a balanced manner across forests. Compensaciones de Uso de Suelo entre la Biodiversidad de arboles y la Produccion Agricola en el Bosque Atlantico Las compensaciones en los servicios ecosistemicos (SE) han recibido mayor atencion porque los servicios de aprovisionamiento a menudo conllevan la perdida de biodiversidad. Cuando los patrones de uso de suelo no son maximamente eficientes en relacion con la productividad, los servicios de aprovisionamiento, como la produccion agricola, a menudo pueden ser incrementados sin perder biodiversidad. El Bosque Atlantico (BA) comprende bosques densos, mixtos y estacionales y tiene altos niveles de endemismo y amenazas antropogenicas. Examinamos las compensaciones entre biodiversidad y produccion agricola en el BA para proporcionar ideas para las decisiones de manejo de uso de suelo. Desarrollamos una medida de la biodiversidad que combina informacion sobre la riqueza de arboles, la singularidad evolutiva y rareza a nivel local Examinamos el grado en que la naturaleza de las compensaciones de los SE difiere entre los 3 tipos de bosque. Evaluamos como afectan las tasas anuales de deforestacion y las practicas de manejo a la biodiversidad y a las ganancias agricolas. Finalmente, probamos si es posible obtener la misma ganancia regional total son reducir la biodiversidad mediante la mejora de las practicas de manejo locales. Los 3 tipos de bosque tuvieron patrones similares de compensaciones de SE, aunque los patrones difirieron en los bosques mixtos. La biodiversidad parecio ser mas sensible al cambio de uso de suelo que a las ganancias agricolas. Ciertos cultivos proporcionaron valores 10 veces mas altos en algunos sitios. El incremento de la produccion agricola puede incrementar las ganancias sin reducir la biodiversidad. Nuestros resultados muestran que para incrementar el bienestar humano sin mayor alteracion del BA se requiere maximizar la produccion agricola. El incremento de la eficiencia del manejo al mantener mas biodiversidad y aumentar los servicios de aprovisionamiento depende del conocimiento del tipo de bosque, de la ventaja comparativa de sembrar cultivos en los mejores sitios y la preservacion de especies de manera equilibrada en los bosques.
