Desertification is the process by which environments beomce more like desert. Over a period of years, the amount of natural vegetation decreases and the soil is exposed to the hot sun. When it rains, the rainwater runs over the surface of the soil (rather than soaking down into it) and the soil can be washed away. The soil becomes degraded or worn out. It's harder to grow crops and food shortages and water shortages may both become more common.
Desertification is a serious issue that affects over 1 billion people around the world. It affects large parts of North America, Africa, Central Asia and Australia, so it affects people in countries at different levels of economic development. However, its most serious effects are on those people who already live in poverty, because desertification makes it even harder for them to make a lving from the land. It is estimated that 90% of the people who are affected by desertification live in the world's poorer countries and that US $42 billion worth of income is lost due to desertification every year.
