Humans impact desert ecosystems in several ways such as practicing problematic agricultural methods, breaking up soils' crust, increasing population and augmenting pollution. Agriculture has changed almost 38% of global land through the removal of tropical forests and the transformation of natural habitats into farmland. The addition of soil nitrogen benefits some plants more than others, potentially altering competitive outcomes. The African Humid Period or Green Sahara was a time between 11,000 and 4,000 years ago when significantly more rain fell across the northern two-thirds of Africa than it does today.

To prevent erosion, plants need to be rotated in certain areas throughout the farm plot. The United Nations Environment Program (UNEP) has estimated that around 70% of the world's known fish species have been completely over-harvested or depleted, creating significant change not only in marine ecosystems but also in land ecosystems, as many mammals and birds depend on aquatic animals as a source of food. Deserts are also the location where oil and gas are collected for use. What is chemical and mechanical weathering? When the winds sweep the sands and dust storms generate, sunlight is trapped in the atmosphere and the reflection of sunlight by ice is disrupted, resulting in more global warming.

To counter human alterations of ecosystems, construction of urban areas are now enforcing that more green space be included in plan designs as a priority. In some areas of northern Africa, the transition from wet to dry conditions occurred slowly; in others it seems to have happened abruptly. Another example of how humans impact deserts environmentally is population increase. Also eroding the soil of the desert as well as destroying many plants and disturbing burrowing animals are off-roading vehicles and ATV's. Otherwise we may be creating more Sahara Deserts, all around the world. For example, stone lines along the soil contours keep it in place, prevent erosion and improve crop yields.
