Factors that contribute in biodiversity loss include climate change and greenhouse gas emissions that exacerbate the hotspots across Africa; as the continent comprises eight hotspots out of 36 on earth including: Succulent Karoo, Horn of Africa, Madagascar, Guinean Forests Of West Africa, Coastal forests of eastern Africa, Afromontane, Cape ...
Red list categories of the IUCN Demonstrator against biodiversity loss, at Extinction Rebellion (2018).. The current rate of global biodiversity loss is estimated to be 100 to 1000 times higher than the (naturally occurring) background extinction rate, faster than at any other time in human history, [25] [26] and is expected to grow in the upcoming years.
Deforestation in the DRC leads to biodiversity loss, soil erosion and contributes to climate change. The DRC is one of 17 megadiverse countries, with a significant wildlife that is harmed by habitat loss. For example, 60% of the forest elephant population drop is due to the loss of shelter caused by illegal logging. [6]
By 2008, deforestation in Africa was estimated to be occurring at twice the world average rate, according to the United Nations Environment Programme (UNEP). [5] [6] [7] Some sources claim that deforestation has already wiped out roughly 90% of West Africa's original forests. [8] [9] Today, deforestation is accelerating in Central Africa. [10]
Africa had the largest annual rate of net forest loss in 2010–2020, at 3.9 million ha, followed by South America, at 2.6 million ha. The rate of net forest loss has increased in Africa in each of the three decades since 1990. It has declined substantially in South America, however, to about half the rate in 2010–2020 compared with 2000–2010.
Habitat loss is perhaps the greatest threat to organisms and biodiversity. [40] Temple (1986) found that 82% of endangered bird species were significantly threatened by habitat loss. Most amphibian species are also threatened by native habitat loss, [ 41 ] and some species are now only breeding in modified habitat. [ 42 ]
Sub-Saharan Africa, notably East Africa, had the world's greatest proportion of undernourished people in 2017, with 28.8% and 31.4%, respectively. Long-term monitoring in North Africa (1978-2014) revealed the disappearance of significant perennial plant species owing to drought and desertification, such as Stipa tenacissima and Artemisia herba ...
Loss of biodiversity results in the loss of natural capital that supplies ecosystem goods and services. Species today are being wiped out at a rate 100 to 1,000 times higher than baseline, and the rate of extinctions is increasing. This process destroys the resilience and adaptability of life on Earth.
