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 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 […]

Estimating the Impacts of Local Policy Innovation: the synthetic control method applied to tropical deforestation

Erin O. Sills, Diego Herrera, A. Justin Kirkpatrick, Amintas Brandao Jr., Rebecca Dickson, Simon Hall, Subhrendu Pattanayak, David Shoch, Mariana Vedoveto, Luisa Young, Alexander Pfaff PLOS ONE 2015 (forthcoming) DOI:10.1371/journal.pone.0132590 Quasi-experimental methods increasingly are used to evaluate the impacts of conservation interventions by generating credible estimates of counterfactual baselines. These methods generally require large samples […]

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 […]

Paper Park Performance: Mexico’s Natural Protected Areas in the 1990s

Allen Blackman, Alexander Pfaff, Juan Robalino Global Environmental Change 31 (2015) pp50-61 Although developing countries have established scores of new protected areas over the past three decades, they often amount to little more than ‘‘paper parks’’ that are chronically short of the financial, human, and technical resources needed for effective management. It is not clear […]

Entry Points for Considering Ecosystem Services within Infrastructure Planning: how to integrate conservation with development in order to aid them both

Lisa Mandle, Benjamin P. Bryant, Mary Ruckelshaus, Davide Geneletti, Joseph M. Kiesecker, Alexander Pfaff Conservation Letters 2015 (online 9/28, doi 10.1111/conl.12201) New infrastructure is needed globally to support economic development and improve human well-being. Investments that do not consider ecosystem services (ES) can eliminate these important societal benefits from nature, undermining the development benefits infrastructure […]

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 […]

Framed field experiment on resource scarcity & extraction: path-dependent generosity within sequential water appropriation

Alexander Pfaff, Maria Alejandra Vélez, Pablo Andres Ramos, Adriana Molina Ecological Economics 120 (2015) 416–429 How one treats others is important within collective action. We ask if resource scarcity in the past, due to its effects upon past behaviors, influences current other-regarding behaviors. Contrasting theories and empirical findings on scarcity motivate our framed field experiment. […]
