Impact of small farmers' access to improved seeds and deforestation in DR Congo
Tanguy Bernard e outros, 2023 · Nature Communications
Subsidizing modern seed varieties without local delivery increased smallholders' clearing of primary forest by 0.108 units (approx. 0.11 ha per household).

However, when the different types of forest are considered, we find significant impacts on deforestation of primary forest (bar cluster 3, P-value of joint F-test 0.00), in particular in villages with no truck delivery (coefficient = 0.108, standard error = 0.038, P-value of two-sided t-test = 0.006).
Contexto
What changed: Households received vouchers for 30% to 100% subsidies to buy modern crop varieties (mainly cereals) at regional multiplier shops. Comparison: Households in control villages where no seed subsidies were offered. Limits: Relies on self-reported plot land-use histories and recall of cleared forest types in an isolated rural setting with informal land tenure.
