SOIL EROSION AND DEGRADATION
Half of the top soil of the planet has been lost in the last 150 years
Loss of many species of our ecosystem
Loss of farming land
Loss of structure, nutrients and salinity in the soil
Increased pollution and sedimentation in rivers
EFFECTS
Land washed and blown away is carried on rivers in which becomes sediment
Less of fish species, sedimentation, water polluted by pesticides and fertilizers
Loss of biodiversity in plants and animals
Urbanisation and development
Tillage reduces soil quality and agricultural productivity
Loss of organic matter, living organisms, nutrients
Climate change
CAUSES
Conversion of natural vegetation in agricultural land
Growing population
Topsoil blown away by wind or washed away by rain
Overgrazing, overstocking and tillage practice
Deforestation
Poor soil management
Pollution
