An estimated 20 million people rely on Lake Chad/ Hadejia-Nguru for their economic activities, a figure that is projected to rise to 35 million by the year 2020 (World Bank 2000). Lake Chad contains the boundaries of four African countries: Cameroon, Chad, Niger, and Nigeria.
What is wrong with Lake Chad?
For years, the prevailing narrative about Lake Chad is that it has been in inexorable decline as a result of the over-extraction of water and climate crisis. A much-repeated factoid is that the lake shrunk by 90% between the 1960s and the 1990s.
What is Lake Chad known for?
Nestled in a low spot within a huge basin in west-central Africa is an isolated blue dot: That’s Lake Chad. Its water sustains people, animals, fishing, irrigation, and economic activity in Chad, Cameroon, Nigeria, and Niger. … The once-great lake now spans less than a tenth of the area it covered in the 1960s.
What is happening to Lake Chad and why is that significant?
Lake Chad has shrunk by 90% since the 1960s, due to climate change, an increase in the population and unplanned irrigation. Its basin covers parts of Nigeria, Niger, Chad and Cameroon, and has been a water source for between 20 million and 30 million people.
Why is Africa drying up?
Poor human management through overgrazing and unsustainable irrigation has resulted in the replacement of natural vegetation with invasive plant species (now covering 50% of the lake), deforestation and the drying of the climate.
What is causing Lake Chad to shrink?
Once one of Africa’s largest lakes, Lake Chad has shrunk by around 90% since the 1960s. This receding water is down to a reduction of precipitation, induced by climate change, as well as development of modern irrigation systems for agriculture and the increasing human demand for freshwater.
Which part is the hottest part of Africa?
A historic heat wave in northern Africa on Thursday, July 5, brought Africa its hottest reliably measured temperature on record: 124.3°F (51.3°C), at Ouargla, Algeria.

Chad is a large landlocked country spanning north-central Africa. It covers an area of 1,284,000 square kilometres (496,000 sq mi), lying between latitudes 7° and 24°N, and 13° and 24°E, and is the twentieth-largest country in the world.
How did lake Mega Chad dry up?
When the lake shrank, it left behind thousands of years of silt deposits (which dried up and formed sand dunes) which has been carried by the wind, perhaps all the way to South America—but only for the last thousand years—which begs the question, where was the Amazon basin getting its fertilizer before that time?
Why is Lake Chad not salty?
It is the largest lake in Central and West Africa and the fourth largest lake on the African continent. … Despite the high rates of evaporation, Lake Chad has low levels of salinity because the more saline waters sink and leave the lake through subterranean conduits in the north.
What is being done to save Lake Chad?
But there have been spirited efforts to rescue the lake from oblivion. The governments in the Lake Chad region are exploring reviving a plan that was first explored in 1982 by an Italian engineering company to construct a 2,400 canal that will tap water from the tributaries of Congo River and drain it into the Lake.
