2012 Sahel drought

From Wikipedia, the free encyclopedia

2012 had a very severe drought in the Sahel, the semiarid region of Africa that lies between the Sahara and the savannas. [1] Countries included in this region are Senegal , Mauritania , Mali , Burkina Faso , Niger , Nigeria , Chad , Sudan , and Eritrea . [2] Droughts in the Sahel occur quite often and tend to reduce the already meager water supply and stress the economies of developing countries in that region. [2]

Future droughts of the Sahel region [ edit ]

The droughts are becoming increasingly more common, worse and more threatening due to global warming . [3] A possible explanation to the aridity trend is the supplements of an oceanography phenomenon called El Nino . [3] An idea is that evaporation is occurring at higher rate due to the change in sea surface temperature , which then impacts the amount of rain the Sahel region receives. [3] Another factor to keep into consideration is the response of Earth's atmosphere to stimulants like greenhouse gases and carbon emissions. [3]

The Sahel region ? a belt up to 1,000 km wide that spans Africa from the Atlantic Ocean to the Red Sea

Societal impacts [ edit ]

Mass famine [ edit ]

Valerie Amos , UN Humanitarian Chief during 2012, released a statement during the year stating that over 15 million people were malnourished in West Africa and the Sahel region. [4] The main contributor to the famine was the drought of Sahel, ensued from a combination of failing crops and El Nino . [3]

Mauritania and Chad recorded a loss in crop yield of over 50% when compared to 2011. Food reserves in the areas affected were very low and combined with corn prices soaring by 60-85% compared to averages over the last five years. In Chad alone this food crisis affected some 3.6 million people. [5] In places like Burkina Faso over 2.8 million were suffering from famine and in Senegal over 800,000 did not have enough to eat.
