What is the problem of land degradation?
Land degradation—the deterioration or loss of the productive capacity of the soils for present and future—is a global challenge that affects everyone through
food insecurity, higher food prices, climate change, environmental hazards, and the loss of biodiversity and ecosystem services
.

What is land degradation and its causes?
Land degradation is caused by multiple forces,
including extreme weather conditions, particularly drought
. It is also caused by human activities that pollute or degrade the quality of soils and land utility. … Desertification is a form of land degradation by which fertile land becomes desert.
