Deforestation and Land Degradation

Trees help bind soil with their roots; when they are removed, the soil becomes vulnerable to being washed away by rain or blown away by wind, reducing land fertility.

Palm oil production is a major driver of deforestation in Cameroon due to the clearing of land for plantations. While other resources exist, palm oil is specifically linked to large-scale forest loss in this region.

Soil conservation involves practices to prevent soil erosion and degradation. Mulching, rock dams, and shelter belts are all recognized methods, whereas deforestation removes vegetation cover and accelerates soil erosion.

Tropical rain forest soils are nutrient-poor because the rapid cycling of nutrients means most organic matter is stored in the biomass rather than the soil. When the forest is cleared, the nutrient cycle is broken and the soil quickly loses its fertility.

Depletion of the water table is caused by a combination of factors including increased demand from population growth, industrial usage, and reduced infiltration due to deforestation.

Deforestation removes the protective cover of trees, leading to soil erosion, increased flood risks due to lack of water absorption, and air pollution due to reduced carbon sequestration.

Trees play a crucial role in the water cycle through transpiration; removing them reduces the amount of moisture released into the atmosphere, leading to less rainfall.

Deforestation reduces the soil's ability to absorb water and removes the vegetation that slows down runoff, which leads to increased flooding.

Forests act as carbon sinks. If they disappear, the CO2 they would have absorbed remains in the atmosphere, causing levels to increase.

Land degradation is caused by various human activities including mining, quarrying, deforestation, and overgrazing. Since all these activities contribute to the loss of soil fertility and land quality, 'All the above' is the correct choice.

Desertification is the process by which fertile land becomes desert, typically as a result of drought, deforestation, or inappropriate agriculture, posing a major threat to the environment.

Overgrazing by livestock removes vegetation cover, which prevents soil erosion and forest regeneration, ultimately contributing to deforestation.

Deforestation is defined as the large-scale removal or clearing of forest areas, usually for agricultural or urban development.

Deforestation is the permanent removal of trees to make room for something besides forest. Reforestation is the opposite process of replanting trees.

Desertification is the process by which fertile land becomes desert, typically as a result of drought, deforestation, or inappropriate agriculture, leading to loss of productivity.
