Resumen
La cuenca del río Grande de Térraba se encuentra en la parte sur de Costa Rica; es una de las cuencas más extensas del país, cubre más del 10% del territorio de la nación. Es una zona con gran biodiversidad y se encuentra ubicada en una de las regiones con los más altos índices de pobreza, económicamente dependiente de las actividades agrícolas extensivas, la pesca artesanal y una creciente actividad turística. A partir del estudio y análisis de fuentes bibliográficas y datos geográficos sobre diferentes variables biofísicas,ha sido posible notar que en los últimos años la cuenca ha experimentado una expansión acelerada de la infraestructura, tanto del sector turístico como residencial, lo que ha ge- nerado cambios importantes en el uso de la tierra, como la disminución de la cobertura vegetal y una mayor presión sobre los recursos naturales de la Península de Osa. El objetivo de este trabajo es identificar y analizar los principales ejes modificadores de la cuenca del Térraba, desde el punto de vista biofísico, con la finalidad de, en próximas etapas de la investigación, proyectar una imagen del futuro de la cuenca o escenarios que podrían presentarse si se continua con las tendencias actuales, con el fin de contribuir a la formulación de políticas y estrategias que contribuyan a garantizar la sostenibilidad de los recursos naturales y a mejorar las condiciones de vida de las poblaciones locales que dependen de estos recursos naturales.
The Térraba River Basin is located in the southern part of Costa Rica and is one of the largest such basins in the country, covering more than 10% of the nation. It is an area with high biodiversity, but is located in a region with the highest poverty rates in that nation and is economically dependent on extensive farming, artisanal fishing and tourism. From the study and analysis of bibliographic sources and geographic data on biophysical varia- bles, it was possible to note that in recent years the basin has undergone a rapid expansion of infrastructure in both the residential tourism sector, which has led to major changes in land use, such as reduction in vegetation cover, and increased pressure on the natural resources of the Osa Peninsula. The aim of this study is to identify and analyze the main drivers of the Térraba Basin modifiers from a biophysical standpoint in order to, in the next stages of research, project possible future scenarios for the basin that could occur if current trends continue, with the goal of contributing to the formulation of policies and strategies to help ensure the sustainability of natural resources and improve the living conditions of the local people who depend on these natural resources.
