- Temperature as Abiotic Factors of the Sahara Desert. a. Extreme temperature ranges. The Sahara Desert experiences high daytime temperatures year-round, with summer averages around 104-113°F in the hottest areas.
- Precipitation. a. Low rainfall patterns. The Sahara Desert receives little rainfall, with annual averages ranging from 0-4 inches. Precipitation occurs sporadically and unpredictably.
- Wind. a. Prevailing wind patterns. The Sahara wind regime is dominated by the dry, sinking air of the subtropical anticyclone and trade winds blowing from the northeast.
- Sunlight. Sunlight is an essential aspect of our environment that is important in many biological processes. It provides energy to support various metabolic activities and influences the growth and development of organisms.

The Sahel is one of the most investigated areas in Africa because of its highly complex and sensitive human and environmental dynamics. The Sahel is a transition zone between the pure desert of Sahara and the woody savanna of the Sudanean zone further south.

Apr 13, 2016 · As in the arid pastoral Sahel, the ecosystem dynamic is of a non-equilibrial nature, but the capacity to respond to rainfall vagaries is affected by the impact of very high stocking rates, locally and seasonally, only sustainable because livestock partially feed on inputs from transhumance and purchased agro-industrial livestock feeds.

Jun 1, 2022 · Abstract. The transitional characteristics of desert grasslands in the Sahel determine the ecosystem’s fragility, which is extremely susceptible to the expansion and reversal of land desertification under the influence of climate change and anthropogenic activities.
Desert ecology is the study of interactions between both biotic and abiotic components of desert environments. A desert ecosystem is defined by interactions between organisms, the climate in which they live, and any other non-living influences on the habitat.
