How does the savanna affect Africa?
Most of sub-Saharan Africa’s agriculture takes place in savanna areas which support most of the continent’s cropland and pasture areas. In savanna areas, more rain may increase tree growth and cover. The way people are using the land can also have a big impact on forests and savannas.
How does the savanna affect humans?
Humans impact the Grassland Savanna by lessening the area of the land by making new space for industrialization. The trees and animals have less space to be so the population decreases with the land, making everything smaller.
How does the African savanna benefit humans?
African savannas provide water, grazing and browsing, food and fuel for tens of millions of people, and have a unique biodiversity that supports wildlife tourism.
What are the human activities in the tropical savanna?
Cheetahs, lions, and vast herds of wildebeest and other antelopes migrate with the seasons to avoid drought. Around the world, savannas are threatened by human actions like logging, development, conversion to agriculture, over-grazing by livestock, and introduction of non-native plant species.
What is life like in the African savanna?
The African savanna ecosystem is a tropical grassland with warm temperatures year-round and with its highest seasonal rainfall in the summer. The savanna is characterized by grasses and small or dispersed trees that do not form a closed canopy, allowing sunlight to reach the ground.
How are human impacts affecting the African savanna?
However, as humans increasingly dominate the Earth system during the Anthropocene (Malhi, 2017 ), four anthropogenic drivers are causing rapid vegetation change across African savannas, threatening biodiversity and ecosystem services.
What to do in the African savanna region?
While a cycle ride may be arduous in spots, the insight you could gain through the close contact with the people of the region and the very fact of being in the thick of the savanna could be well worth the effort. You can rent or buy bicycles nearly everywhere across the continent in most tourist areas.
What kind of vegetation are found in savannas?
Savannas cover more than 50% of the African continent, encompassing diverse ecosystems with a wide range of woody cover, from densely wooded Miombo woodlands to Serengeti grasslands with scattered trees. Co-dominance of trees and grasses is common to these ecosystems, with the ground layer dominated by shade-intolerant C 4 grasses.
How does land clearance affect the African savanna?
The direction of these effects is indicated by pointed arrows (positive) and flat-ended arrows (negative). Land clearance limits herbivory and fire by fragmenting landscapes and reducing their connectivity, and therefore can potentially cause increased woody cover in uncleared areas.
