Desertification, climate change and sustainable development
Pace Law School
The classification of deserts based on the level of rainfall combined with different average temperatures. There are tropical, temperate and cold deserts.

and polar deserts
·Overgrazing on fragile arid and semiarid rangelands
· Deforestation without reforestation
· Surface mining without land reclamation
· Irrigation techniques that lead to increased erosion
· Salt buildup and waterlogged soil
·Farming on land with unsuitable terrain or soils
· Declining living standards
· Swelling numbers of environmental refugees
Land degradation affects the quantity and quality of freshwater supplies. Drought and desertification are associated with lower water levels in rivers, lakes, and aquifers. For example, unsustainable irrigation practices can dry the rivers that feed large lakes; the Aral Sea and Lake Chad.
Another example is a southern part of Russian Plain – the republic of Kalmikia.
