Africa's Environmental Issues December mini-project
This week we have been learning about these environmental issues in
Africa: deforestation, desertification, and water pollution
as listed in our standards. Download A Continent in Chaos
Download Timber Exploitation, Environment Insecurity and Conflicts in Africa
We've added others!
WATER PRESSURE!
We'll start reviewing environmental policies in
Africa. We'll discuss the fact that not only is water scarce, but the
available water is often unclean. Students will examine their own
water usage as a comparison.

DESERTIFICATION
Increased population and livestock pressure on marginal lands are accelerating desertification in the semiarid Sahel region of western Africa, which has also endured extensive and severe droughts since the 1960s. Intensive agriculture and overgrazing compacts the soil, diminishing its capacity to hold water and exposing the soil to erosion. Slashing and burning of natural forest and bushland has added to the destruction by removing a natural barrier to wind erosion and the root systems that slow topsoil erosion. Dust storms have therefore become frequent where the ground has been stripped of vegetation.

TOXIC WASTE DISPOSAL
Electronic waste – discarded computers, cell phones and the like – from the U.S. and Europe poisons children in Ghana who earn a living in the dump, burning it and extracting copper and other valuable materials with their bare hands.
Tons of toxic waste collected from British municipal dumps is being sent illegally to Africa in flagrant breach of this country's obligation to ensure its rapidly growing mountain of defunct televisions, computers and gadgets are disposed of safely.
Hundreds of thousands of discarded items, which under British law must be dismantled or recycled by specialist contractors, are being packaged into cargo containers and shipped to countries such as Nigeria and Ghana, where they are stripped of their raw metals by young men and children working on poisoned waste dumps.

ENERGY EXTRACTION
SOIL
In sub-Saharan Africa, intensive land use due to increased population pressures is mining soils of nutrients needed to sustain agriculture. Sowing crops season after season without fertilizers -- unaffordable for most farmers -- drains the land of much-needed minerals. Even natural fertilizers like post-harvest stubble and livestock dung are being scavenged from the land and used for fuel. Limited water availability has restricted crop diversification and the adoption of proper soil management. Nutrient depletion has caused crop production to stagnate or decline many African countries, thereby endangering food and economic security.
