The image features a grouped bar chart titled "Percentage of Land Area Affected by Desertification", plotting "Percentage of Land Area (%)" on the vertical axis (scaled from 0 to 30 in increments of 5) against "Region" on the horizontal axis across two years: 1990 and 2010. For North America, the percentage of land area affected is approximately 12% in 1990 and 15% in 2010. For Europe, the values are approximately 9% in 1990 and 11% in 2010. For Sub-Saharan Africa, the figures stand at 25% in 1990 and 32% in 2010. For Australia, the affected land area is approximately 14% in 1990 and 13% in 2010.

The bar chart illustrates the proportion of land area affected by desertification in four different regions of the world in 1990 and 2010.
Overall, it is clear that Sub-Saharan Africa was the most affected region in both years, while the figures for the other three regions changed only slightly. Australia was the only region to record a decline.
Looking at North America and Europe, the figures for both regions ranged from approximately 9% to 15%. In both cases, the figures in 2010 were slightly higher than those in 1990, reaching around 15% and 11%, respectively. Europe recorded the lowest proportions of land affected by desertification in both years.
The figure for Sub-Saharan Africa stood at approximately 25% in 1990 before rising considerably to just over 30% in 2010. By contrast, Australia experienced the smallest change, with the figure falling slightly from around 14% in 1990 to 13% in 2010.
