Deforestation Spillovers from Costa Rican Protected Areas

Juan Robalino, Alexander Pfaff, Laura Villalobos LACEEP Working Paper Series WP78 Robalino-et-al-Park-Spillovers-LACEEP-WP78.Spillovers can significantly reduce or enhance the effects of land-use policies, yet there exists little rigorous evidence concerning their magnitudes. We examine how national parks within Costa Rica affect the clearing of forest nearby. We find that average deforestation spillover impacts are not significant […]

Protected area types, strategies and impacts in Brazil’s Amazon: public PA strategies do not yield a consistent ranking of PA types by impact

Alexander Pfaff, Juan Robalino, Catalina Sandoval, Diego Herrera Philosophical Transactions B 2015 volume 370 (online http://dx.doi.org/10.1098/rstb.2014.0273) The leading policy to conserve forest is protected areas (PAs). Yet, they are not a single tool: land users and uses vary by PA type; and public PA strategies vary in the extent of each type, as well as […]

Protected Areas’ Impacts on Brazilian Amazon Deforestation: examining conservation – development interactions to inform planning

Alexander Pfaff, Juan Robalino, Diego Herrera, Catalina Sandoval PLOS ONE 2015 (forthcoming) DOI:10.1371/journal.pone.0129460 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 […]

Evaluating Interactions of Forest Conservation Policies on Avoided Deforestation

Juan Robalino, Catalina Sandoval, David N. Barton, Adriana Chacon, Alexander Pfaff PLoS ONE 10(4):e0124910 (2015) doi:10.1371/journal.pone.0124910 We estimate the effects on deforestation that have resulted from policy interactions between parks and payments and between park buffers and payments in Costa Rica between 2000 and 2005. We show that the characteristics of the areas where protected […]

Governance, Location and Avoided Deforestation from Protected Areas: greater restrictions can have lower impact, due to differences in location

Alexander Pfaff, Juan Robalino, Eirivelthon Lima, Catalina Sandoval, Diego Herrera World Development 2014 volume 55, pp. 7–20 For Acre, in the Brazilian Amazon, we find that protection types with differences in governance, including different constraints on local economic development, also differ in their locations. Taking this into account, we estimate the deforestation impacts of these […]

Global protected area impacts

Global protected area impacts

Lucas N. Joppa, Alexander Pfaff Proceedings of the Royal Society B 2010 doi:10.1098/rspb.2010.1713 Protected areas (PAs) dominate conservation efforts. They will probably play a role in future climate policies too, as global payments may reward local reductions of loss of natural land cover. We estimate the impact of PAs on natural land cover within each […]

Reassessing the forest impacts of protection: The challenge of nonrandom location and a corrective method

Lucas Joppa, Alexander Pfaff Ann. N.Y. Acad. Sci. 1185 (2010) 135–149 Protected areas are leading tools in efforts to slow global species loss and appear also to have a role in climate change policy. Understanding their impacts on deforestation informs environmental policies. We review several approaches to evaluating protection’s impact on deforestation, given three hurdles […]

Measuring the effectiveness of protected-area networks in reducing deforestation

Kwaw Andam, Paul Ferraro, Alexander Pfaff, Juan Robalino, G. Arturo Sanchez-Azofeifa PNAS 105(42):16089-16094 Global efforts to reduce tropical deforestation rely heavily on the establishment of protected areas. Measuring the effectiveness of these areas is difficult because the amount of deforestation that would have occurred in the absence of legal protection cannot be directly observed. Conventional […]
