Can any one tell me the climatic problems of africa and what are the actions taken by the goverment for this and what should be the actions to resolve Africa's climatic problem?
Answers
Answer:
Impacts on Water Supply and Quality. Observable effects of climate change on water resources in Africa include: flooding, drought, change in distribution of rainfall, drying-up of rivers, melting of glaciers and the receding of bodies of water.

Answer:
Africa has seen a decrease in rainfall over large parts of the Sahel and Southern Africa, and an increase in parts of Central Africa. Over the past 25 years, the number of weather-related disasters, such as floods and droughts, has doubled, resulting in Africa having a higher mortality rate from droughts than any other region.
1. Impacts on weather patterns
Flooding is the most prevalent disaster in North Africa, the second most common in East, South and Central Africa, and the third most common in West Africa.
Between July 2011 and mid-2012, a severe drought affected the entire East Africa region and was said to be “the worst drought in 60 years.”
2. Impacts on Water Supply and Quality
Observable effects of climate change on water resources in Africa include: flooding, drought, change in distribution of rainfall, drying-up of rivers, melting of glaciers and the receding of bodies of water.
3. Impacts on Agriculture and Food
Across Africa the landscape is changing. Droughts, heat stress and flooding have led to a reduction in crop yields and livestock productivity.
4. Impacts on Human Health
Climate-sensitive diseases and health impacts can be high in poor countries that have minimal resources to treat and prevent illness. Examples of climate related health impacts include:
Frequent and severe heat stress linked to sustained increases in temperature
The reduction in air quality that often accompanies a heat wave can lead to breathing problems and worsen respiratory diseases.
Impacts of climate change on agriculture and other food systems increases rates of malnutrition and contributes to poverty.
5. Impacts on Shelter
Severe flooding and intense droughts has led to the destruction of many homes, shelters and villages across Africa. Conflicts over resources also exacerbate these impacts and, in turn, contribute to the ongoing migration within and between countries in Africa.
Extreme events displace large amounts of people, especially those who are unable to respond and rebuild after disasters, due to lack of resources.
6. Impacts on Vulnerable Population
Women, children and the elderly are more vulnerable to climate change impacts across Africa. Women labourers often experience additional duties as caregivers and as well as from societal responses to climate change after extreme weather events (eg, male migration).
7. Impacts on National Security
Climate change impacts have the potential to exacerbate national security issues and increase the number of international conflicts. Conflicts often occur over the use of already limited natural resources, fertile ground and water. Access to consistent and dependable sources of water is greatly valued in many African regions. However, changes in the timing and intensity of rainfall have threatened water availability and are causing conflicts over this limited resource.
8. Impacts on ecosystems
Climate change has already led to changes in freshwater and marine ecosystems in eastern and southern Africa, and terrestrial ecosystems in southern and western Africa. The extreme weather events have demonstrated the vulnerability of some of South Africa’s ecosystems. The migration patterns, geographic range and seasonal activity of many terrestrial and marine species have shifted in response to climate change.
Despite the fact that the African continent has contributed the least to anthropogenic factors causing climate change, Africa is the worst hit.
