Why is land degradation important?
Land degradation will remain an important global issue for the 21st century because of its adverse impact on agronomic productivity, the environment, and its effect on food security and the quality of life. The productivity of some lands has declined by 50% due to soil erosion and desertification.
What are the three process of land degradation?
The main soil degradation process are: (1) soil erosion by water and wind; (2) Development of extreme soil reaction (acidification; salinization/alkalization); (3) physical degradation (structural destruction; compaction; extreme moisture regime); (4) biological degradation; (5) unfavourable changes in the nutrient …
What is the main cause of land degradation?
The major causes of land degradation include, land clearance poor farming practices, overgrazing, inappropriate irrigation, urban sprawl, and commercial development, land pollution including industrial waste and quarrying of stone, sand and minerals.

What is land degradation in simple words?
Land degradation—the deterioration or loss of the productive capacity of the soils for present and future—is a global challenge that affects everyone through food insecurity, higher food prices, climate change, environmental hazards, and the loss of biodiversity and ecosystem services.
What are the two reasons for land degradation?
Two reasons for land degradation are deforestation and overuse of chemical fertilisers. Why is land considered an important resource? Solution : Land is considered an important resource because it is used for different purposes such as agriculture, forestry, mining, building houses, roads and setting up of industries.
What is degradation process?
Degradation processes reduce the service life of concrete structures, resulting in social, environmental and economic damage. The main climate variables that interfere with the concrete degradation mechanisms are: temperature, relative humidity, precipitation, wind, waves and tides.
What are the causes and effect of environmental degradation?
Environmental degradation comes about due to erosion and decline of the quality of the natural environment. It is caused directly or indirectly by anthropogenic activities that extract various environmental resources at a faster rate than they are replaced, and thus depleting them.
What is land degradation What are its causes which is the biggest cause of land degradation?
The main causes of land degradation are – Deforestation, overgrazing leading to a reduced growth of vegetation, reduced diversity of plant species, excessive growth of unwanted plant species, soil erosion, and degradation of land due to cattle movement, excessive use of fertilizers and pesticides, Industrialization.

What is the result of land degradation on human life?
Land degradation and desertification can affect human health through complex pathways. As land is degraded and deserts expand in some places, food production is reduced, water sources dry up and populations are pressured to move to more hospitable areas.
