Several critical evidence gaps The study highlights three critical gaps where a stronger evidence base is needed to better target efforts to reduce deforestation; 1. A globally and temporally consistent data product on deforestation is needed. 2. Except for oil palm and soy, we lack data on the coverage and expansion of specific commodities to know which are more important, with our understanding of global pasture and grazing lands being especially dire. 3. We know comparatively very little indeed about tropical dry forests, and forests in Africa.
