Types of soil degradation

Main causes of degradation

- water erosion 56%- wind erosion 28%- chemical degradation 12%- physical degradation 4%

- overgrazing 35%- deforestation 30%- agricultural activities 27%- overexploitation of vegetation 7%- industrial activities 1%

Study case: Brasilian Amazon

• Bauxit mine – production of litter to improve soil fertility (Acacia mangium x Eucalyptus pellita)

Study case: India

• Wastelands – alkaline and saline soil

• Plantation of 10 000 seedlings of different species

• Survived 635 after 13.5 years but soil improved

Study case: China

• Influence of reforestation on eroded land

• Cinnamomum caphor x Lespedeza bicolor
