11 Number of contracts Value of contracts (R$ billion) nutrients in the soil is crucial to the success of recovery and lowers the cost of the operation in the long term, as the cost of new recovery is substantially higher (Zimmer et al. [...] The vector information of the polygons is cross-referenced with information from satellite images (raster), obtaining the area of each type of land use within the polygon by weighting the intersection of the polygon with the cells (grids) of the image.22 This collection returns information on land cover and land use, including the area within the polygon covered by pasture, crop area, native fores. [...] In any case, the average area of the polygons in the study sample is 160 hectares, and half of the distribution is above the median of 91 hectares, which is well above the pixel size. [...] This data is presented in Figure 5, which shows the percentage of pasture relative to the total area of the polygons, according to the year the ABC Recuperação credit was contracted, marking the moment as the year the funds were released. [...] Results of the Empirical Analysis Average Effects The estimation of equation (1), which analyzes the percentage of pasture within the polygon area and its breakdown by pasture quality classes, supports the descriptive findings: the impacts observed in the areas receiving ABC Recuperação credit are modest.
