Impact of climate change on the continent of Africa
  1. Water issues: Life is regulated by access to water for agriculture , domestic use and hydroelectric power. Many large rivers e.g Nile,cause potential for conflict between users. Demand outstrips supply of water for 25% of Africans. Poverty is the reason why they don't have access to clean water.
    1. Food insecurity: 70% of population are subsistence farmers, many will be unable to feed themselves if water supplies dry up or crops fail. Increased locust plagues may also threaten food supplies.
      1. Natural resources: Poor people especially living in marginal environments, depend directly on wild plants and animals to support their way of life. Loss of bioviersity due to climate change will threaten them.
        1. Africa is the continent that makes least contribution to global warming, yet is must vulnerable to climate change. Temperatures are expected to rise by 3-4 degrees above the mean global change. Rainfall likely to increase in the equatorial region but decrease to the north and south of that band.
          1. Why is Africa so vulnerable to climate change
            1. Poverty: Lack of adaptation e.g growing different crops and Mitigation e.g reduce the impact of climate change through flood defences
              1. Many parts of Africa in debt to MEDCS such as the WB, IMF. They raise the money by selling cash crops e.g Tea, soya, cocoa, coffee, oppose to growing food causing Africa to starve.
                1. Coastal erosion and sea level rise cause these issues to develop.
                  1. High rates of HIV/AIDS, in common places, means that they are unable to work
                2. Health: Vector borne diseases e.g malaria and water borne diseases e.g diarrhoea could increase with climate change. Moreover, 80% of health services rely on wild plants for remedies which are under threat.
                  1. Development of coastal zones: Movement of environmental refugees from countryside puts pressure on coastal zones, especially in north & West Africa. Refugees set up home in shanty towns e.g Lagos. Also, 60% of Africans live in coastal zones, many at risk of Coastal erosion. The threats likely to come from sea level rise, casuing flooding. Most of the continents infrastructure, roads, bridges and buildings would be lost.
                    1. Desertification: Major destroyer of grasslands. It is increased by unreliability or decreased rainfall
                      1. Poverty: Two thirds of LEDCS are located in Africa, An unjust trading system forces many countries to sell their exports (e.g Mali cotton) at low prices to compete with subsidised European and North American products
