Explanation:

The problem of land degradation

PRESSURES ON THE REGION'S AGRICULTURAL LAND ARE LEADING TO EXTENSIVE LAND DEGRADATION. THE CAUSES ARE POVERTY, LAND SHORTAGE AND INCREASING POPULATIONS

In 1992 developing countries in Asia and the Pacific accounted for just less than 54 percent of the world population - nearly 3000 million people. Yet these countries had only 17 percent of the world's land resources.

Even so, countries in Asia and the Pacific are relatively well fed compared, for example, to much of Africa and parts of Central and South America. This is because they have made profitable use of new agricultural technology, such as fertilizers, high-yielding crop varieties, mechanization and irrigation. During the period ]961-85, 93 percent of the region's increase in cereal production was due to increased production inputs. As a result food production has more than kept pace with population increase.
