The loss of agricultural land is due largely to land degradation, such as erosion, which is when soil components move from one location to another by wind or water. Agricultural land is also being lost because it is being converted for other purposes, such as highways, housing and factories.
How much land does agriculture use?
43 million acresOf California’s approximately 100 million acres of land, 43 million acres are used for agriculture. Of this, 16 million acres are grazing land and 27 million acres are cropland.
Human expansion throughout the world caused that agriculture is a dominant form of land management globally. Human influence on the land is accelerating because of rapid population growth and increasing food requirements.
Land cover and land‐use patterns on Earth reflect the interaction of human activities and the natural environment [ 1 ]. Human population growth together with competitive land use causes land scarcity, conversion of wild lands to agriculture and other uses.
3. Results and discussion
With the growing world population the requirements are grown to cover the food demand. Human expansion throughout the world caused that agriculture is a dominant form of land management globally, and agricultural ecosystems cover nearly 40% of the terrestrial surface of the Earth.
Agriculture is a dominant form of land management globally. Rapid population growth as primary driving force connected with increasing food requirements generate great pressure on future land use, environment, natural resources, and ecosystem services.

How does deforestation affect soil?
Deforestation removes vegetation, which anchors soil in place. Without enough trees, soil is vulnerable to erosion and nutrient loss. The absence of roots causes topsoil to easily wash or blow away, leading to decreased soil quality and increased landslides. It’s estimated that a third of the world’s arable land has been lost to soil erosion and degradation since 1960. Once land is cleared and roots are ripped away, cash crops like coffee and soy are planted which can make erosion worse, since their roots cannot anchor into the soil like those of a tree.
