4.3.2. Changes That Occurred during the Study Period

Analysis done during the period of the study period highlights some changes between the variables. Among the most significant changes, the results underline an extension of other components on the grassland. 2083.29 km2 of grassland was transformed into agricultural areas (Table 4). Similarly, 5.42 km2 of grassland was transformed into urban and built up. In addition, 3.63 km<sup>2</sup> of grassland was transformed into a permanent wetland. We have noticed a significant change in grassland, in the study area which has continued to increase. This change is especially noticeable in the Kaffrine region (Figure 4). The balance of land-use changes observed over the study period shows that the most important relationships are between grassland and the other land use pattern, namely cropland and urban up and built.
