Hard ground makes too great resistance, as air makes too little resistance, to the surfaces of roots. —Jethro Tull, 1733 Under natural conditions, soils are generally stable and effectively store water, nutrients and carbon, which are cycled efficiently with plants, animals and the atmosphere. With the onset of agricultural development—as early as 10,000 years ago []

27.04.2019Land degradation is a negative change in the quality of land, usually induced by a mixture of natural and man-made causes. It affects the land's topsoil, the vegetation that grows on it, and the nearby water sources. It is a global issue with millions of people being affected, even forcing them to relocate in some cases.

01.03.2022Logging and mining. Logging, similar to deforestation, causes soil erosion as it removes the trees protecting the soil from the elements, anchoring it to the ground. Tree roots act to hold the soil together, and their leaves and branches form canopies that prevent the impact of the harsh elements. Image Credit: Rich Carey/Shutterstock.
