Abstract
En este estudio, evaluamos la representación de las unidades biogeográficas en áreas protegidas nacionales (APN) y sub-nacionales (APS), así como en territorios indígenas oficialmente reconocidos (TI) de Bolivia. Compilamos información cartográfica disponible sobre APN, APS y TI en Bolivia, y la comparamos con la propuesta sugerida de jerarquización de unidades biogeográficas (regiones, provincias y sectores). Para cada unidad biogeográfica, calculamos la meta de representación bajo los siguientes tres criterios: 1) la meta del 17% propuesta por las metas de Aichi de la CDB (Convención sobre la Diversidad Biológica), b) la meta de representación esperada por la cobertura de cada unidad biogeográfica con relación a la superficie total de Bolivia, y c) la meta de representación calculada para cada unidad biogeográfica basados en la relación área-representación esperada. Detectamos una marcada subrepresentación de las regiones de los Andes tropicales y la Brasileño-Paranaense en las APN, mientras que la región chaqueña estuvo notoriamente sobre representada. Para el caso de las provincias y sectores biogeográficos, detectamos una tendencia general hacia la subrepresentación en APN, APS y TI. Nuestros resultados sugieren cautela en el uso e interpretación de la meta del 17% recomendada por las metas de Aichi de la CDB. Los resultados también resaltan la importancia de las APS y los TI en la representación de la vegetación en Bolivia, representando ejemplos de «otras medidas eficientes de conservación basadas en áreas» (OEABCM por sus siglas en inglés); sin embargo, sugerimos cautela sobre el papel de los TI en las tierras altas.
In this study, we evaluated the representation of biogeographical units in national (NPA) and subnational (SPA) protected areas, as well as in officially recognized indigenous territories (IT) of Bolivia. We compiled available cartographic information on Bolivia's NPA, SPA and IT, and compared it with suggested proposal and hierarchization of biogeographic units (regions, provinces, and sectors). For each biogeographic unit, we calculated the representation target under the following three criteria: 1) the 17% target proposed by the Aichi targets of the CBD (Convention on Biological Diversity), b) the representation target expected by the cover of each biogeographic unit in relation to Bolivia's total surface, and c) the expected representation target calculated for each biogeographic unit based on the relationship area - expected representation. We detected a marked under-representation of the Tropical Andean and Brasilian-Paranaense regions in the NPA, whereas the Chaco Region is was notoriously over-represented. For the case of biogeographic provinces and sectors, we detected a general tendency towards under-representation in the NPA, SPA and IT. Our results suggest cautiousness in the use and interpretation of the 17% target recommended by the Aichi targets of the CDB. The results also highlight the potential importance of the SPA and the IT in the vegetation representation in Bolivia, the latter two being examples of "other efficient conservation measures based on areas" (OEABCM); however, we suggest cautiousness on the role of IT in the highlands.
