Abstract

Soil is the major natural resource on which human life depends for the production of food, feed, fiber, renewable energy and raw materials, as well as the protection of the planet's natural ecosystems and climate system. Increasing soil degradation and subsequent ecosystem degradation is a current concern in agriculture and the environment. Soil degradation poses many challenges to feed the world's growing population. This food insecurity will also reduce the income of the agricultural sector, which will lead to a decrease in economic income. Soil degradation will lead to environmental threats, the extinction of animals and plants, the reduction of biodiversity, water loss, and disruption of water and carbon cycles. The use of new technologies such as biological crusts has provided great hope for the recovery and restoration of degraded ecosystems. Inoculation of biological crusts, especially cyanobacteria, has had positive results on improving soil conditions and restoration degraded soils. In this article, has been introduced the biocrusts communities considering cyanobacteria species to restore degraded soils. We reported the results of cyanobacteria applications in soil conservation in arid environments of Iran.
