Climate Change Effects in Africa
Africa is the continent most at risk from environmental changes
due to global warming as the continent is home to many of the
world's poorest nations, countries which will not be able to afford
mitigation strategies on their own.
Below are some of the consequences of global warming which are
specific to Africa:
Desertification: The grasslands of the Sahel, a band
of semiarid land running across the continent south of the Sahara
desert, are already shrinking. As climate models predict warmer
temperatures and less rainfall for this region under global warming,
the desertification and loss of productive land is expected to
accelerate. Additionally, reductions in rainfall are predicted
for some regions in southern Africa, meaning the Kalahari and
Namib deserts at the southern end of the continent could also
grow in size.
Food Security: The economies of many African nations
are still based on subsistence agriculture. Increased numbers
of droughts and floods could lead to food shortages and famines.
Health: A warmer climate could expand the range of carriers
of malaria, yellow fever, dengue fever, and other vector-borne
diseases.
Water Supply: The lack of adequate fresh water is a
problem faced by several countries in Africa. Regions of the
continent such as the Sahel and southern Africa, where precipitation
is expected to decline, may face even more severe water shortages.
Refugees: Environmental pressures such as dwindling
food and water supplies may lead to conflict between struggling
nations, unleashing migrations of environmental refugees on the
African continent.
Coastal Erosion: While all coastal African nations must
cope with the rising sea level, changes may be especially profound
in West Africa where coastal storms are common. Of course, sea
level rise poses a particular challenge for Small Island States
such as the Comoros and Seychelles.
