Desertification in Africa is exacerbated by human factors such as deforestation, overgrazing, and unsustainable farming methods such as monoculture and excessive use of chemical fertilizers. For example, deforestation reduces the quantity of plants that may anchor soil and protect it from erosion, whereas overgrazing depletes vegetation and ...
The large scale felling of trees and the resulting decreases in forest areas are the main environmental issues of the African Continent. Rampant clearing of forests and land conversion goes on for agriculture, settlement and fuel needs. [3] Ninety percent of Africa's population requires wood to use as fuel for heating and cooking.
The immediate cause of desertification is the loss of most vegetation. This is driven by a number of factors, alone or in combination, such as drought, climatic shifts, tillage for agriculture, overgrazing and deforestation for fuel or construction materials.
The negative impact of agriculture is an old issue that remains a concern even as experts design innovative means to reduce destruction and enhance eco-efficiency. [2] Animal agriculture practices tend to be more environmentally destructive than agricultural practices focused on fruits, vegetables and other biomass. The emissions of ammonia ...
The direct causes of deforestation within the DRC are well understood and have been identified consistently by many sources. [2] [3] [9] The direct causes are as follows: 1) road infrastructure development, 2) slashing and burning the forests to transform forest land into agricultural land, 3) the collection of fuelwood and charcoal, and lastly 4) unregulated artisanal and small-scale logging.
The main sources of Africa's 3.6% share of the world's Carbon dioxide emissions are gas flaring in the Niger Delta and coal-fired power plants in South Africa. [23] But, the continent's forests are rapidly disappearing because of desertification and deforestation, which has negative consequences for both Africa and the climate at large. [24]
Desert farming is the practice of developing agriculture in deserts. As agriculture depends upon irrigation and water supply, farming in arid regions where water is scarce is a challenge. However, desert farming has been practiced by humans for thousands of years. In the Negev, there is evidence to suggest agriculture as far back as 5000 BC. [1]
Long-term drought in Nigeria has resulted in desertification and a shortage of land for raising cattle and growing crops. [1] To obtain land for farming or grazing, farmers and herdsmen are encouraged to go to new areas, which frequently leads to violence [2] [3] [4] Herdsmen and farmers have been engaged in increasingly violent fights over the previous two years.
