Desertification in Senegal - the future for agriculture and the survival…
Desertification in Senegal - the future for agriculture and the survival of communities
Consequences
Social
Loss of traditional knowledge and culture
Political
Political tensions as farmers may want to claim or contest more arable land
Political tensions as leadership is given responsibility to organise solutions for these issues
Environmental
Loss of biodiversity
Loss of water-retention
Loss of nutrients in soil
Economic
Loss of yield
Loss of income -> may create emigration
Demographic
Loss of traditional knowledge and culture
May create an ageing population as youth emigrates to larger cities e.g. Dakar
Managing desertification in Senegal
Green Wall Initiative
Strengths
Creates a biodiverse hub
Increases nutrient density of soil
Increases water-holding capacity of soil
Limitations
May come at a large economic cost
Has to be supported by people along the Wall -> the success of the initiative is based on community effort
Local Afforestation
Strengths
Limitations
Causes and acceleration of desertification
Physical/Natural
Lack of vegetation
Lack/low rainfall (<50cm per year)
Lack of clay -> too much sand = no water-holding capacity
Human
When climatic variability coincides with unsustainable human activities
Unsustainable consumption of water
Removal of water-holding capacity for mining/development purposes
Place (background, context)
Land degradation in humid and semi-arid areas; leading to the spread of desert-like conditions
