In 2003, three road investments were proposed in the vicinity of the Barú Volcano National Park in the province of Chiriquí: (1) a one-lane road from Cerro Punta to Boquete, via the Park; (2) the so-called “southern route” outside the park, from Cuesta de Piedra to Boquete via Palmira; and (3) paving the access roads as far as the guard stations at the Park’s Eastern and Western entrances (see figure 2). Conservation Strategy Fund (CSF) and The Nature Conservancy (TNC) conducted an economic analysis of the proposals between February and April, 2003. We employed the “Roads Economic Decision Model,” developed by the World Bank in 1999. The research was jointly funded by the Nature Conservancy and Conservation International (CI), and was one of several factors that led to cancellation of the proposed road through the park. The lower-impact "Southern Route" was selected instead.
