In fact, it was largely for this reason that the U.S. military established most of its training facilities there. Desertification is the process of fertile land turning into desert over time. The amount of pollution created by building new cities and dams should be monitored by governmental agencies and should help inform policy. Social media has helped increase awareness of the benefits of plant-based diets and sustainable, plastic-free living. Homemade compost is used to provide a fertility boost for the soil. Because grasslands are typically found in drier climates, the plant life is susceptible to fire. Land erosion caused by deforestation is leading to more changes in land and water ecosystems. If a human has more information about how gentle this ecosystem is and how their actions may affect this desert biome and all of its intricate interactions, then they are less likely to purposefully harm this biome. Vegetation, which is a good indicator of the impacts of climate variability and human activities, can reflect desert ecosystem dynamics. In some areas of northern Africa, the transition from wet to dry conditions occurred slowly; in others it seems to have happened abruptly. Explore the likely benefits with Desert Botanical Garden!

There are other implications of trouble associated with desertification such as a depression in the economy and famine. The end of the African Humid Period is a lesson for modern societies living on drylands: if you strip the vegetation, you alter the land-atmosphere dynamics, and rainfall is likely to diminish. Comments. Development through mining or residential use is one way we are harmin our deserts. Human activities can either positively or negatively impact Earth's resources. Forests will be at risk of dying due to changes in temperature and moisture content, deserts will experience significant drought and famine, storms will become much more intense, and changes in precipitation will bring drought, famine, and an increased rate of species extinctions.

Biome is often referred to as ecosystem. Over-harvesting is the process of harvesting organisms and resources faster than their populations can recover. It displaces wildlife that depend on these ecosystems for sustained life, forever changing the natural habitat. After wildfires occur, many groups replant organisms that perished in the fire. It lies in the subtropical latitudes dominated by high-pressure ridges, where the atmospheric pressure at the Earths surface is greater than the surrounding environment.
