Costa Rica's payment for environmental services program: intention, implementation, and impact.
(Conserv Biol, 2007-10)We evaluated the intention, implementation, and impact of Costa Rica's program of payments for environmental services (PSA), which was established in the late 1990s. Payments are given to private landowners who own land ... -
Estimating the Impacts of Local Policy Innovation: The Synthetic Control Method Applied to Tropical Deforestation.
(PLoS One, 2015)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 for statistical ... -
Evaluating interactions of forest conservation policies on avoided deforestation.
(PLoS One, 2015)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 ... -
Global protected area impacts.
(Proc Biol Sci, 2011-06-07)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 ... -
High and far: biases in the location of protected areas.
(PLoS One, 2009-12-14)BACKGROUND: About an eighth of the earth's land surface is in protected areas (hereafter "PAs"), most created during the 20(th) century. Natural landscapes are critical for species persistence and PAs can play a major role ... -
Indigenous lands, protected areas, and slowing climate change.
(PLoS Biol, 2010-03-16)Recent climate talks in Copenhagen reaffirmed the crucial role of reducing emissions from deforestation and degradation (REDD). Creating and strengthening indigenous lands and other protected areas represents an effective, ... -
Protected Areas' Impacts on Brazilian Amazon Deforestation: Examining Conservation-Development Interactions to Inform Planning.
(PLoS One, 2015)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 ... -
Reduction in urinary arsenic levels in response to arsenic mitigation efforts in Araihazar, Bangladesh.
(Environ Health Perspect, 2007-06)BACKGROUND: There is a need to identify and evaluate an effective mitigation program for arsenic exposure from drinking water in Bangladesh. OBJECTIVE: We evaluated the effectiveness of a multifaceted mitigation program ...
