This executive summary describes a study by the Climate Policy Initiative on the adoption of the Direct Planting System (PD) in Brazil. The research identifies social learning—learning from neighbors and colleagues—as a key driver of technology diffusion, while noting that soil heterogeneity acts as a significant barrier. The document argues that public policy should focus on information dissemination and temporary training centers, particularly in areas with homogeneous soils, rather than relying solely on financial subsidies like the ABC program.
