Agricultural Land Use alters the Landscape. Plants suffer from osmotic stress when they fail to take up water, even when it is present in the soil. Strong water currents ruin constructions, damage farmlands, increase sedimentation, and contaminate aquatic bodies. Soil salinization (salinisation) is the increase of salt concentration in soil and is, in most cases, caused by dissolved salts in the water supply.

In addition, rain water typically contains low amounts of dissolved salts, but irrigated water can contain much higher salt concentrations. With ongoing research, there are likely to be new ways that humans can adapt agriculture to the pressing issue of soil salinization. When a vegetated area is cleared for an alternate land cover type, such as a field for agriculture or a golf course, the hydrological balance of the area is disrupted. A traditional subsistence agricultural system in which practitioners depend on the seasonal movements of livestock within marginal natural environments.

The time when human beings first domesticated plants and animals and no longer relied entirely on hunting and gathering. The proper management of the aforementioned soil salinization is imperative for achieving most of the Sustainable Development Goals (SDGs) of the United Nations. Because salts are water-soluble, they can enter into soil environments through groundwater, flooding, or irrigation.2 Salts may accumulate in soil for a variety of reasons, all of which relate to some disruption in water and water-soluble salt dynamics.
