The diversity of topography, climate, geology and people in South Africa presents a wide variety of natural and cultural resources. It is notably considered one of the most biologically diverse countries in the world due to its species diversity, rate of endemism and diverse ecosystems.
Why is Africa rich in biodiversity?
Africa is immensely rich in biodiversity. Its living organisms comprise around a quarter of global biodiversity and it supports the earth’s largest intact assemblages of large mammals, which roam freely in many countries.
Why is biodiversity important in South Africa?
In addition to its own intrinsic value, South Africa’s biodiversity provides an important basis for economic growth and development. … Biodiversity and healthy ecosystems provide us with essential services – pollination of crops, a regular supply of clean water, and prevention of flooding and soil erosion.
How biodiverse is South Africa?
South Africa ranks as the third most biodiverse country in the world. It is recognised for high levels of endemism and is home to over 95,000 known species. The country also boasts a diverse range of biomes, from forests to deserts, estuaries and marine systems.
Why is Africa so biodiverse?
Africa is host to remarkable biodiversity, with many endemic and endangered mammals and plants. … As a matter of fact, most African economies are largely dependent on their natural resources such as agricultural lands, forests, water resources, ecosystems and ecosystem services.
Does Africa have a lot of biodiversity?
Africa is home to a rich and diverse animal, plant, and marine biodiversity that provide critical ecosystem services, driving the continent’s economy and serving as buffers to climate change.
What is the status of biodiversity in Africa?
The report finds that: overall, biodiversity in African continues to decline driven by a combination of human-induced factors; freshwater ecosystems are especially threatened; there is continued deforestation and forest degradation; and the impacts of climate change exacerbate pressures on ecosystems and biodiversity.
What are the main threats to biodiversity in South Africa?
The four-year study led by the South African National Biodiversity Institute (SANBI) found that major pressures on South Africa’s biodiversity are habitat loss, changes to freshwater flow (e.g. as a result of over-abstraction), overuse of some species, pollution, climate change and invasive alien species.
What is the main ecosystem in South Africa?
Ecological Regions Of South Africa
|Ecological Regions Of South Africa (as per World Wide Fund for Nature)||Biome|
|Kalahari Acacia-Baikiaea woodlands||Tropical and Subtropical Grasslands, Savannas, and Shrublands|
|Kalahari xeric savanna||Deserts and Xeric Shrublands|
|Karoo||Southern Temperate Freshwater|
What are some examples of biodiversity?
Most people recognize biodiversity by species—a group of individual living organisms that can interbreed. Examples of species include blue whales, white-tailed deer, white pine trees, sunflowers, and microscopic bacteria that can’t even be seen by the naked eye.
What are the main industries in South Africa?
Economy of South Africa
|Main industries||mining (world’s largest producer of platinum group metals, gold, chromium), automobile manufacturing, metalworking, technology, machinery, textiles, iron and steel, IT, chemicals, fertiliser, foodstuffs, manufacturing, commercial ship repair.|
What are the two least protected biome in South Africa?
Grassland, Thicket, and Nama-Karoo: the least protected biomes. Grassland is also one of South Africa’s largest and most threatened biomes.
Why is South Africa a megadiverse country?
This is as a result of the country’s highly varied climate, topography and geology, which also has led to extremely high levels of endemism across its many different ecosystems, meaning that many South African species are found nowhere else on earth.
Why did megafauna survive in Africa?
The prevailing theory is that the megafauna in Africa evolved along with us, and had a good fear of humans bred into them. The megafauna in the other continents didn’t have enough time to adapt to our presence, and were killed off as easy meat as a result.
Why are cereal yields low in Africa?
The weakness in the productivity of crops across Sub Saharan Africa is not only related to the poor soils in many countries (CIMMYT, 2015) but also to the limited use of essential inputs that are needed to raise the productivity level. These inputs include the use of improved seeds, fertilizers, irrigation, pesticides.
Is Africa protected?
Africa, as a whole, has made significant strides over the past ten years towards increasing the amount of protected terrestrial areas. While there are inevitable challenges and setbacks, African countries are guardians to some of the earth’s most vital ecoregions.
