The process of contamination of the land surface of our planet is referred to as land pollution. It results from human activities that cause the contamination of soil and degradation of land. Dumping of human and industrial waste in soil, harmful agricultural practices, and harmful chemicals are the primary causes of land pollution.
Facts and Statistics
Land pollution is the result of misuse of soil. Poor agricultural practices lead to degradation of soil. Wrong methods of soil management and harmful irrigation practices lead to soil pollution. Monoculture, overgrazing, and improper methods of irrigation are some of the main reasons why the quality of soil degrades. 40% of the world's agricultural land is said to have degraded.
A study done in Calabar South, Nigeria, showed that about 60% of the agricultural land in this region is degraded, and has mainly resulted in decreased productivity of the land. Apart from wrong agricultural practices, urbanization and high population density (that causes a rising competition for land use) have been attributed as the causes of land degradation in the region. Soil erosion and nutrient loss have also led to decreased productivity in Calabar South and it is predicted that if erosion continues at the current rate, there will be an 87% drop in yield by 2020.
Dumping of garbage underground is one of the leading causes of land pollution. Also known as a landfill, it is a very old way of waste disposal. If not managed well, landfills can cause environmental pollution, as well as contamination of groundwater and soil. More than 80% of the items in landfills can be recycled but we rarely do that.
