How many globally depend on dry lands and how many can potentially be affected by the current desertification trends?
Answer:
Desertification is the term used to describe the degradation of the land in arid, semi-arid, and dry sub-humid regions, collectively referred to as drylands, which is brought on by a variety of factors, including climatic changes and human activity.
Worldwide, 24% of the land is deteriorating. These deteriorating areas support almost 1.5 billion people. Cropland and rangeland make up roughly 20% and 20–25%, respectively, of the degraded land.
Over the past several decades, desertification in some dryland areas has expanded in both extent and intensity. Over 2 billion people live in drylands, which make up 40–41% of Earth's total surface. One billion people are thought to be in danger from further desertification, with estimates of the percentage of drylands that are already degraded at 10–20%.
The total area affected by desertification at 6–12 million square kilometres, and the percentage of dryland residents who live in desertified areas at 1-6%.
