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.
Desertification is a gradual process of increased soil aridity.Desertification has been defined in the text of the United Nations Convention to Combat Desertification (UNCCD) as "land degradation in arid, semi-arid and dry sub-humid regions resulting from various factors, including climatic variations and human activities."
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]
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 ...
A satellite image of the Sahara, the world's largest hot desert and third largest desert after Antarctica and the Arctic. Desert greening is the process of afforestation or revegetation of deserts for ecological restoration (biodiversity), sustainable farming and forestry, but also for reclamation of natural water systems and other ecological systems that support life.
Consequently, deforestation, largely driven by human activities, has played a significant role in the desertification of Ghana. [4] Climate change is a significant contributor to desertification in Ghana. [19] The country is especially susceptible since it relies heavily on rain-fed agriculture and has inadequate capacity for mitigation and ...
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.
