How does urbanization lead to land degradation?
Urbanization not only destroys and fragments habitats but also alters the environment itself. For example, deforestation and fragmentation of forest lands lead to the degradation and loss of forest interior habitat as well as creating forest edge habitat.

What are the examples of land degradation?
Examples of soil degradation
- water erosion (includes sheet, rill and gully erosion)
- wind erosion.
- salinity (includes dryland, irrigation and urban salinity)
- loss of organic matter.
- fertility decline.
- soil acidity or alkalinity.
- structure decline (includes soil compaction and surface sealing)
- mass movement.

Regular updates and information on degraded land is essential for the Government to plan necessary measures to tackle degradation processes and to plan for reclamation programmes.
What are effects of land degradation?
Its impacts can be far-reaching, including loss of soil fertility, destruction of species habitat and biodiversity, soil erosion, and excessive nutrient runoff into lakes. Land degradation also has serious knock-on effects for humans, such as malnutrition, disease, forced migration, cultural damage, and even war.
How does Urbanisation cause pollution?
