ABSTRACT
T was 4.2 Mha (7.9%) in 1992 and 3.2 Mha (6.5%) in 1997. The land area affected by erosion decreased over time in all erosion severity classes. The average rate of decline in land area over the 15-year period with erosion
>
T was 0.07 Mha/yr. The mean rate of decline was 0.25 Mha/yr or 0.5%/yr for

T class, 0.024 Mha/yr or 1.1%/yr for 1-2T, 0.017 Mha/yr of 1.9%/yr for 2-3T, 0.011 Mha/yr or 2.6%/yr for 3-4T, 0.005 Mha/yr or 2.5%/yr for 4-5T, and 0.013 Mha/yr or 2.7%/yr for

5T class of soil erosion. In contrast, the decline in land area under pasture for
the same period was 0.6%/yr. Therefore, the rate of decline in the area affected by severe erosion was more than that of the change in area under pasture.
