Protected Areas' Impacts on Brazilian Amazon Deforestation: Examining Conservation-Development Interactions to Inform Planning.

Pfaff A, Robalino J, Herrera D, Sandoval C - PLoS ONE (2015)

Bottom Line: For Brazil's Legal Amazon, we estimate the average impact of protection upon deforestation and show how protected areas' forest impacts vary significantly with development pressure.Further, it reveals significant variation in PA impacts along development-related dimensions: for example, the PAs that are closer to roads and the PAs closer to cities have higher impact.Planners have multiple conservation and development goals, and are constrained by cost, yet still conservation planning should reflect what our results imply about future impacts of PAs.

ABSTRACT
Protected areas are the leading forest conservation policy for species and ecoservices goals and they may feature in climate policy if countries with tropical forest rely on familiar tools. For Brazil's Legal Amazon, we estimate the average impact of protection upon deforestation and show how protected areas' forest impacts vary significantly with development pressure. We use matching, i.e., comparisons that are apples-to-apples in observed land characteristics, to address the fact that protected areas (PAs) tend to be located on lands facing less pressure. Correcting for that location bias lowers our estimates of PAs' forest impacts by roughly half. Further, it reveals significant variation in PA impacts along development-related dimensions: for example, the PAs that are closer to roads and the PAs closer to cities have higher impact. Planners have multiple conservation and development goals, and are constrained by cost, yet still conservation planning should reflect what our results imply about future impacts of PAs.

pone.0129460.g002: Creation of Protected Areas: hectares by year (cumulative).

Mentions: Fig 2 presents the number of protected hectares for these categories during 1959–2008. Most of protected areas were implemented during 1990–1999, especially in the cases of the State Conservation Units and the Indigenous Lands. However, most of the land that has been protected within Federal Conservation Units was protected during the 1980–1989 and 2000–2008 periods. Again considering this on the whole, most of the PAs were created before our 2000–2004 period of deforestation, while of the rest a large share were created before our 2004–2008 time period.
