Abstract: En el presente articulo exploramos el papel de los PSA en la proteccion de la biodiversidad en paises en desarrollo. Para ello analizamos el vinculo entre biodiversidad y servicio ambientales. Exploramos que complejidades inherentes a su naturaleza ecologica emergen a la hora de su cuantificacion, monitoreo y evaluacion economica. A continuacion interpretamos este marco teorico a traves de 11 proyectos de PSA biodiversidad en paises en desarrollo donde analizamos su impacto para la conservacion y el desarrollo rural. El metanalisis muestra que los pagos genericos por biodiversidad suelen requerir menos monitoreo y estan asociados a pagos por superficie, meintras que los pagos para conservar especies emblematicas suelen realizarse por hogar y estan sujetos a un mayor seguimiento y control. Estos proyectos han obviado debates academicos sobre la funcionalidad y el monitoreo de la biodiversidad, optando por soluciones pragmaticas como el heco de ligar la biodiversidad a especies emblematicas o al uso de la tierra. Por ello discutimos e identificamos algunos elementos para avanzar hacia nuevas conceptualizaciones de PSA que se ajusten mas a las necesidades locales de cada region. The present paper analyses the links between Payments for Environmental Services (PES) and biodiversity conservation in developing countries. We first discuss some of the inherent complexities and uncertainties when linking biodiversity to ecosystem services and the related inconsistencies to deal with ecosystem services monitoring, quantification and biodiversity economic valuation. We then apply such theoretical framework in 11 biodiversity PES field projects to evaluate the impacts on biodiversity conservation and rural development. We find that PES designed for conserving ecosystem biodiversity with no concrete species targeting, require less monitoring and payments are done on a per surface basis. Biodiversity PES projects targeting concrete species require more monitoring and control and payments are done on a per family basis. These projects have not addressed the polemic of the lack of consistent links between ecosystem functions and biodiversity, and have adopted a practical approach where biodiversity depends on land uses or target specific species threaten by extinction. We finally suggest some design features to better adjust PES to local needs while coping with forthcoming socio-economic challenges.
