Because of heavy dependence on rainfed agriculture, about 60% of Sub-Saharan Africa is vulnerable to frequent and severe droughts (Esikuri, 2005). … Although Africa has a huge water resource, there is large variation in its spatial and temporal distribution.
Why is Africa vulnerable to drought?
These include land degradation, poverty and climate change. … The continent also has low adaptive capacity making it particularly vulnerable and exposed because of high rates of poverty, financial and technological constraints as well as a heavy reliance on rain-fed agriculture.
Why is Africa the most vulnerable to climate change?
Africa will be one of the regions most impacted by the adverse effects of climate change. Reasons for Africa’s vulnerability are diverse and include low levels of adaptive capacity, poor diffusion of technologies and information relevant to supporting adaptation, and high dependence on agro-ecosystems for livelihoods.
Why more countries in Africa face the risk of drought?
Taking drought risk in Africa as an example, it is estimated that although drought hazard is the worst in northern African countries, drought risk tends to be the highest in central African countries owing to their growing population and socioeconomic vulnerability  .
Why are areas in Africa at risk of drought and desertification?
Whereas over cultivation, inappropriate agricultural practices, overgrazing and deforestation have been previously identified as the major causes of land degradation and desertification, it is in fact a result of much deeper underlying forces of socio-economic nature, such as poverty and total dependency on natural …
Why do developing countries struggle with drought?
The causes of droughts are essentially natural, but climate change increases the drought severity, frequency, duration, and spatial extent. The impacts of droughts are also strongly exacerbated by anthropological activities, such as deforestation, overgrazing, soil degradation, and water mismanagement.
How can we prevent droughts?
Choose a water-efficient irrigation system such as drip irrigation for your trees, shrubs, and flowers. Turn irrigation down in fall and off in winter. Water manually in winter only if needed. Put a layer of mulch around trees and plants to reduce evaporation and keep the soil cool.
Which country in Africa is most affected by climate change?
MADAGASCAR (Climate Risk Index: 15.83)
Adverse weather events have also made the African country one of the most vulnerable to climate change with 72 deaths — 0.27 per 100,000 inhabitants — about 568 million dollars in economic losses and a drop in per capita GDP of 1.32%.
How will Africa stop climate change?
Solutions to global warming in Africa include effective land use planning to avoid forest degradation, developing renewable energy, and limiting the expansion of coal-fired power plants. … New efforts are underway to ensure effective land use planning, balancing local subsistence needs with conservation.
How does Africa contribute to global warming?
Africa can easily be said to contribute the least of any continent to global warming. Each year Africa produces an average of just over 1 metric ton of the greenhouse gas carbon dioxide per person, according to the U.S. Department of Energy’s International Energy Annual 2002.
What country has the worst drought?
Botswana ranks as the country with the highest drought risk mainly due to its high exposure combined with its relatively high vulnerability (S1). …
How many people die from drought in Africa?
Where are the risks of drought in Africa?
Based on exposure measured as a function of the density of agricultural production per square kilometer, the risks associated with drought are greatest in southwestern Ethiopia and western Kenya.
Which region of Africa is most at risk from desertification?
Desertification is the process of land turning into desert as the quality of the soil declines over time. Many countries around the world suffer from the problems caused by desertification but it is the Sahel region of Africa where the effects are greatest.
What is Africa doing about desertification?
The Great Green Wall. One ambitious initiative created to reduce desertification in Africa is the Great Green Wall. Once completed, the Great Green Wall will be the largest living structure on the planet, spanning more than 4,500 miles across the entire Sahel.
Does desertification cause drought?
These unsustainable land uses place enormous pressure on the land by altering its soil chemistry and hydrology. … Droughts can persist for months or years, but eventually subside; lands undergoing desertification never recover past productivity.
