The region is characterized by a dry hot climate, high temperatures and low rainfall (100–600 mm per year). [44] So, droughts are the rule in the Sahel region. [45] The Sahel has lost approximately 650,000 km 2 of its productive agricultural land over the past 50 years; [46] the propagation of desertification in this area is considerable. [47 ...
With the Sahel region being the most vulnerable and extensively affected by desertification, a project known as the Great Green Wall was launched in 2007 for the Sahara and Sahel. Its lofty goal is to create an 8,000-kilometer natural wonder over Africa's whole width in order to enhance the quantity of fertile land bordering the Sahara desert ...
A key feature in the region is the heterogeneous distribution of hydrologic extremes in space and time. For instance, El Niño can cause droughts in one part of the region and floods in the other. This is also a common situation within a country, e.g., in Ethiopia.
Some climate change effects: wildfire caused by heat and dryness, bleached coral caused by ocean acidification and heating, environmental migration caused by desertification, and coastal flooding caused by storms and sea level rise. Effects of climate change are well documented and growing for Earth's natural environment and human societies. Changes to the climate system include an overall ...
Deforestation on a human scale results in decline in biodiversity, [211] and on a natural global scale is known to cause the extinction of many species. [212] [213] The removal or destruction of areas of forest cover has resulted in a degraded environment with reduced biodiversity. [118]
Natural forces cause some variability, but the 20-year average shows the progressive influence of human activity. [2] Present-day climate change includes both global warming—the ongoing increase in global average temperature—and its wider effects on Earth's climate.
Because of its effect on agriculture, on flora and fauna, and on the climates of nations such as Bangladesh, Bhutan, India, Nepal, Pakistan, and Sri Lanka – among other economic, social, and environmental effects – the monsoon is one of the most anticipated, tracked, [3] and studied weather phenomena in the region. It has a significant ...
Jizera Mountains in Central Europe in 2006 Tree dieback because of persistent drought in the Saxonian Vogtland in 2020. Forest dieback (also "Waldsterben", a German loan word, pronounced [ˈvaltˌʃtɛʁbn̩] ⓘ) is a condition in trees or woody plants in which peripheral parts are killed, either by pathogens, parasites or conditions like acid rain, drought, [1] and more.
