Article Soil salinity: A serious environmental issue and plant growt...

According to the paper entitled "Land (& Soil) Degradation: Types, Causes, Effects, & Solutions (Ways To Prevent It) prepared by Better Meets Reality, land degradation is the blanket term usually used to describe a number of land and soil degradation issues such as soil contamination, soil erosion, desertification, and more. Land and soil degradation can take many forms – up to 36 degradation types exist. Some of the major types of degradation include soil erosion, soil contamination, desertification, soil acidification, soil salinity.

Causes for land and soil degradation can differ from country to country, and region to region, and even from open land to agricultural land. Some of the major general causes include wind and water weathering of soil, deforestation and clearing of land, intensive or unsustainable agricultural practices, mining, urbanization, and human development, carrying of contaminants by air and water, leaching and runoff of contaminants, improper management/disposal of waste, natural or severe weather events, indirect factors, and human population growth.

For agricultural land, in particular, the main causes of erosion on agricultural land are intensive cultivation, overgrazing, poor management of arable soils, and deforestation.

Some solutions to land degradation might include more sustainable farming practices that help protect long term soil health and yield, reducing deforestation rates and planting more trees and plant life, examining our diets to eat more sustainably produced foods, more sustainable mining practices, ensure landfills are properly sealed, monitor industrial waste and dispose of it properly, limit runoff from highways and roads, limit water pollution, limit air pollution, and funding large scale projects to restore damaged and degraded soil and land.

Some land degradation such as the effects of water and wind erosion may be largely irreversible – at least over the span of thousands of years (topsoil can take millennia to form again naturally). 

Other types of land degradation are reversible – but, can differ in the amount of time and money required to address them, and some types of land degradation are easier to address than others.
