On average, forest cover is 2.9% higher in areas enrolled in the IFA program compared to non-enrolled, control areas facing similar deforestation pressures (95% confidence interval [1.51:4.38])
Contexto
What changed: Smallholders received annual cash payments of 2.4 to 3.6 million COP conditional on placing at least 30% of their forested land under conservation contracts. Comparison: Matched non-enrolled 10-hectare grid cells using doubly robust difference-in-differences. Limits: Single-cohort evaluation over a one-year window (2021–2022); inability to match on socio-economic traits or unmapped illegal roads may affect counterfactual parallel trends.
