Are government incentives effective for avoided deforestation in the tropical Andean forest?
Pablo Cuenca e outros, 2018 · PLoS ONE
Enrolment in Ecuador's Socio Bosque Program reduced the probability of deforestation between 2008 and 2014 by 1.5 percentage points relative to matched control forest plots.

Contexto
What changed: Forest lands received conservation payments of US$20–30/ha/year under 20-year voluntary conservation contracts. Comparison: Matched 30x30 m forest cells outside the program using nearest-neighbor propensity score matching on geographical, biophysical, and accessibility covariates. Limits: Identification assumes unconfoundedness; unobserved factors affecting both participation and deforestation pressure could introduce bias, though tested via sensitivity analysis.
