Global warming is increasing the incidence of drought
, which dries up water holes. Higher temperatures may produce an increasing number of wildfires that alter desert landscapes by eliminating slow-growing trees and shrubs and replacing them with fast-growing grasses.
What are some problems in the Sahara desert?
Desertification, Over-Hunting, and Habitat Destruction
are only a few of the problems in the Sahara.
What problems are in the desert?
Increasing evaporation and dust storms
are pushing deserts out into communities at their edges. This desertification is exacerbated by human exploitation of ecosystems that border deserts, causing land degradation, soil erosion and sterility, and a loss of biodiversity.
Human Activity
Over-cultivation, poorly drained irrigation systems, mismanagement of available water, digging for fossil fuels and introduction of invasive species
are only some of the environmental problems in desert biomes created by humans.
What problems do desert animals face?
Intense heat, searing sun, and lack of water
are just a few of the challenges facing desert animals. Animals that live in the hot desert have many adaptations. Some animals never drink, but get their water from seeds (some can contain up to 50% water) and plants.

2.5 million inhabitants
—less than 1 person per square mile (0.4 per square kilometre).
How do humans negatively impact the desert?
Human exploitation of fragile ecosystems can lead to the droughts and arid conditions characteristic of desertification
. Effects include land degradation, soil erosion and sterility, and a loss of biodiversity, with huge economic costs for nations where deserts are growing.
What can be done to protect the desert?
Major desert restoration techniques include:
planting and seeding, managing water, manipulating soil properties, and providing cover
. Controlling non-native species often also is part of restoration and subsequent maintenance management in the restored ecosystem (D'Antonio & Meyerson 2002).
Does desert have two S's?
desert/ dessert
Dessert has two s's because you always want two
