Environment in Africa: continuity & change
? Africa is ancestral home to our species. ? Over centuries humans have adapted their
lives & activities to environment. ? Humans evolved to conform to their
environments & for greater part of their existence on earth have been constantly molded by their environments. ? Colonialism in Africa changed localized nature of regional economies & introduced new pressure from outside.
Main Environmental Issues:
? Deforestation ? Desertification ? Soil erosion & degradation ? Development & the environment ? can the
two be reconciled?
Deforestation
? Typically occurs when trees are cut down to provide firewood & timber as well as to free up space for crop cultivation.
? In case of Africa, rapid urbanization, drought, civil wars, oil & mineral extraction, & bush fires have also contributed.
? Major reason for deforestation in Africa is poverty & economic underdevelopment.
? 90% of African population uses fuelwood for cooking.
? With rapid increase in population growth & higher rates of urbanization the need for fuelwood as source of energy will continue to grow.
Deforestation
? The major cause of deforestation in Africa is clearing forest for crop production.
Problem is related to increased population growth
Use of slash & burn/shifting cultivation but with greatly reduced fallow periods.
? Logging for timber has also contributed and timber exports have been promoted by the structural adjustment programs of the IMF and World Bank.
