This is a case study about the evolution of thinking in Bolivia on how to attain sustainability of their protected area network. It is an interesting story because it addresses so many elements of what is required to achieve sustainability in addition to just finances. As a country with one of the richest biodiversity heritages in the world, Bolivia also faces a great array of protected area threats ranging from mining to deforestation (400,000 Ha./yr), agriculture (including coca), and uncontrolled fires.
