The largest basin in the world is Congo basin.

The shape of "basin" is like a basin, with high sides and low middle, hence the name. Where is the largest basin in the world, what is its name and how many square meters does it cover? Let's take a closer look!

The largest basin in the world is Congo basin.

Congo Basin (Africa) is 3.37 million square kilometers.

Congo basin is the largest basin in Africa and the largest basin in the world, also called Zaire basin. Located in central and western Africa, it is square with the equator passing through it. The area is about 3.37 million square kilometers. It is located between Lower Guinea Plateau, South Africa Plateau, East Africa Plateau and Low Azande Plateau, and is located in Cameroon, Central Africa, Democratic Republic of Congo, Equatorial Guinea, Gabon and Congo.

The origin of Congo basin

Congo Basin is located between Guinea Plateau, South Africa Plateau, East Africa Plateau and Azande Plateau, and between Cameroon, Central African Republic, Democratic Republic of Congo, Equatorial Guinea, Gabon and Congo.

This is a tectonic basin with undisturbed thick sedimentary rocks at the bottom, forming a flat and monotonous terrain. Only some sporadic low cliffs caused by faulting have broken this monotonous landscape to some extent.

Sedimentary rocks are deposited in the inner lake. Later, due to the rising of the earth's crust, the original Congo River (Zaire River) passed through the western edge of the basin, and the inner lake gradually disappeared. Today, two large lakes in the southwest of the basin are its remnants. The basin is surrounded by slopes of adjacent plateaus, and its basement crystalline rocks are widely exposed.

Lake edge erosion

1. The initial depression was caused by faults.

2. Because the surrounding plateau is complete and the situation is closed, water gradually accumulates into a lake due to rainy weather.

3. Then the lake gradually erodes the edge, causing the lake to leak. Due to excessive logging, the remaining virgin forests in central Africa are decreasing at an alarming rate. At the beginning of the last century, Africa was extremely rich in tropical rain forest resources, which was the second largest tropical rain forest area in the world after Latin America. The forest coverage rate exceeded 60%, but today it is less than 10%.

According to the survey results of FAO, the speed of forest harvesting in this area has exceeded the limit of forest regeneration capacity. 1In March 1999, the first summit on the protection of forest ecosystems in Central Africa was held in Yaoundé, Cameroon. The meeting adopted the Yaoundé Declaration on Forest Protection.

In February 2000, the United Nations General Assembly adopted a resolution calling on the international community to provide technical and financial assistance to help Central African countries implement the Yaoundé Declaration. The Partnership Plan launched at the World Summit on Sustainable Development held in Johannesburg, South Africa in September 2002 also includes a plan to protect the natural resources of the Congo Basin in Central Africa.

On February 6, 2005, the presidents of seven Central African countries said in Congo and Brazzaville that they would take active measures to establish a regional organization to protect the species diversity in Congo basin. At the closing ceremony of the one-day Second Summit on the Protection of Forest Ecosystem in Central Africa, Cameroonian President Biya, Gabonese President Bongo, Equatorial Guinean President Obiang, Chadian President Deby, Congolese President Kabila, Central African President Bozizé and Congolese President Sassou signed a resolution promising to protect the biodiversity and its ecosystem in the Congo Basin.

The presidents of the seven countries support the establishment of a regional investment institution, and draw a certain proportion of funds from the export income of forests and animals to establish a fund to finance regional forest cooperation institutions or projects. At the same time, they called on the international community, especially the developed countries of the Paris Club, to forgive the debts of Central African countries and help them advance the projects of protecting forest ecosystems.
