aquaculture will decline - Madagascam Prawn fisheries and Tuna fisheries of the West Coast of Africa will decline
large scale agriculture may suffer - Madagascan vanills, Ghana's cocoa beans, coffee (all climate dependent)
Migration could lead to pressure on jobs, food and water supply - could lead to conflict
Coastal cities could be wiped out by rising sea levels/storms
Government may be under pressure to invest huge amount of money in coastal protection, GM crops (drought) etc.
1-2% decrease in Africa in GDP
Niger river basen - secreased river flow in the last 50 years - impact on HEP scheme that was planned
Affected: farmers at subsitence levels, Big businesses and TNCs - Starbucks - coffee - Ghana, cadburys - cocoa - Ghana, tourism is affected - travel companies, hotel chains declines - declines as coral reefs are damaged be bleaching - safari animals become harder to spot - Kenya, Egypt, Madagascar most affected textile companies - cotton from Egypt - health impacts on their workers, prices may increase
Crop yields could be reduced by as much as 50% - problem of malnutrition even worse

impact of climate change on Africa
Social:
Increased drought - crops fail, livestock die - subsistence farmers hugely affected, famine, starvation (Malawi and Ethiopia mostly affected)
Increase in flooding and droughts - food insecurity in Mozambique
Migration of environmental refugees to coastal cities e.g. Lagos, Accra
Water - demand exceeds supply for 25% of Africans
Food - 70%-80% are subsitence farmers - increased flooding/drought - crops won't grow - won't be able to feed themselves
Natural resources - those living in marginal environments rely on wild plants and animals to support their way of life.
Health - increawsed vector borne diseases and water borne diseases e.g. Malaria & diarrhoea
Coastal flooding - 60% of Africans live in coastal zones (Accra, Lagos) at risk of flooding and erosion. The risk will increase as sea levels rise.

Any positives?
THERE ARE NO POSITIVES CREATED AS A RESULT OF GLOBAL WARMING IN AFRICA
3 of 4
impact of climate change on Africa
Key Points:
Afria is the most vulnerable region in terms of human vulnerability
the population is dependent on climate sensitive resources (local water and ecosystems) and they have very limited ability to adapt
There are 55 countries in Africa - in 1010 2/3 of them were among the world's 50 poorest countries.
Many countries owe millions in debt
They do not contribute much to global warming but it will affect them the most: Temperature increase by 3-4 degrees above mean global average, tainfall will increase in equatorial regions - flooding, rainfwall with decrease in the North and South - drought.
