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]
In 2005, Nigeria had the highest rate of deforestation in the world, according to the Food and Agriculture Organisation of the United Nations (FAO). [6] Deforestation in Nigeria is caused by logging, subsistence agriculture, and the collection of wood for fuel. According to the gfy, deforestation has wiped out nearly 90% of Africa's forest.
In their analysis of global forest loss, Philip Curtis and colleagues used satellite images to assess where and why the world lost forests between 2001 and 2015. The breakdown of forest loss globally, and by region, is shown in the chart. Just over one-quarter of global forest loss is driven by deforestation.
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] In fact, the rate of deforestation in Zimbabwe is one of the highest globally – directly affecting ecosystems, biodiversity, and livelihoods. [3]
Rates of deforestation vary around the world. Up to 90% of West Africa's coastal rainforests have disappeared since 1900. [56] Madagascar has lost 90% of its eastern rainforests. [57] [58] In South Asia, about 88% of the rainforests have been lost. [59]
Despite the slightly different estimates for deforestation in different regions of Ethiopia, given deforestation rates remain the same, the country will have lost its last tree of high forests within about 27 years. And with it will go the world's only original wild populations of Coffea arabica. The economic loss of that genetic resource ...
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 ...
English: In this paper we afford a quantitative analysis of the sustainability of current world population growth in relation to the parallel deforestation process adopting a statistical point of view. We consider a simplified model based on a stochastic growth process driven by a continuous time random walk, which depicts the technological ...
