Ninety percent of Africa's population requires wood to use as fuel for heating and cooking. As a result, forested areas are decreasing daily, as for example, in the region of equatorial evergreen forests. According to the United Nations Environment Programme, Africa's desertification rate is twice that of the world's. [4] Deforestation of ...
During the last two decades of the 21st century, Kenya's rate of deforestation has remained consistent. The first decade of the century experienced 2,914.55 hectares in a primary forest lost and 19,401 hectares lost in tree cover while the second decade of the century has experienced a total of 2,099.74 hectares lost in primary forest and 17,167 hectares lost in tree cover.
Forests currently cover around 45% of the country’s total land area, but deforestation is an increasingly pressing issue, resulting in forests disappearing quickly. The rate of deforestation in the country accelerated to 327,000 ha per year (1.9%) during the years 2000 and 2010 and is also currently the highest in Southern Africa. [2]
At the beginning of the 20th century, around 420,000 km 2 (160,000 sq mi) or 35% of Ethiopia's land was covered with forests. Recent reports indicate that forests now cover less than 14.2% [25] or even only 11.9% as of 2005. [27] Between 1990 and 2005, the country lost 14% of its forests or 21,000 km 2 (8,100 sq mi).
Apart from Northern Africa, East African countries show the second highest decline rates of conservation forests in the continent. In a forest resource assessment of Ethiopia, Reusing found that within 17 years (1973–1990) high-forest cover decreased from 54,410 to 45,055 km² or from 4.72 to 3.96% of the land area. [5]
On a regional scale, Africa has the highest annual rate of net forest loss at 3.9 million ha in 2010–2020, followed by South America at 2.6 million ha. While the rate of net forest loss for Africa has increased since 1990, it has declined in South America by about one half between the decades 2000-2010 and 2010–2020.
A study of the girth of 70,000 trees across Africa has shown that tropical forests fix more carbon dioxide pollution than previously realized. The research suggested almost one-fifth of fossil fuel emissions are absorbed by forests across Africa, Amazonia and Asia. Simon Lewis stated, "Tropical forest trees are absorbing about 18% of the carbon ...
The anticipated water shortage is a potential problem for the future. For example, the damming of the Omo river by the Gilgel Gibe III Dam together with the plan to use 30% to 50% of the water for sugar plantations will create significant environmental problems. Up to 50% of Lake Turkana's water capacity will be lost.
