Land degradation is the effect of human processes causing a change in the value of the environment and earth.
This is largely related to agricultural use, caused mainly by:
– clearcutting and deforestation – at a pace exceeding natural growth and/or replanting
– nutrient loss through poor rotation – lack of regulation or lack of education
– overgrazing – tragedy of the commons
– industrial waste and improper disposal – lack of control or scientific understanding
– Mainly soil erosion
– Oversalination (salting) through water irrigation OR waterlogging
– Increases in either acidity or alkalinity
It’s estimated that up to 40% of agricultural land is “seriously degraded.” Soil erosion is one of the major environmental issues today that frequently goes unnoticed, which can also be easier to repair than most.
