A satellite image of the Sahara, the world's largest hot desert and third largest desert after Antarctica and the Arctic. Desert greening is the process of afforestation or revegetation of deserts for ecological restoration (biodiversity), sustainable farming and forestry, but also for reclamation of natural water systems and other ecological systems that support life.
For instance, it might be difficult to tell if desertification or desert expansion is the result of climate change or human activity. [19] Desertification in Africa is exacerbated by human factors such as deforestation, overgrazing, and unsustainable farming methods such as monoculture and excessive use of chemical fertilizers.
Typical deserts are indicated by the hyper-arid category (light yellow). [1] Desertification is a type of gradual land degradation of fertile land into arid desert due to a combination of natural processes and human activities. The immediate cause of desertification is the loss of most vegetation.
Humans have long made use of deserts as places to live, [104] and more recently have started to exploit them for minerals [105] and energy capture. [106] Deserts play a significant role in human culture with an extensive literature. [107] Deserts can only support a limited population of both humans and animals. [108]
Domesticating wild plant and animal species for human benefit has occurred many times all over the planet, and has a major impact on the environment, both positive and negative. Wildlife can be found in all ecosystems. Deserts, rain forests, plains, and other areas—including the most developed urban sites—all have distinct forms of wildlife ...
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. Deserts are arid regions that are generally associated with warm temperatures; however ...
Earth Optimism is a movement promoting a positive outlook towards problems related to environmental or climate issues. Earth Optimism provides an alternative narrative to mainstream environmental news by highlighting the potential for humans to positively impact the environment by making small changes at individual and community levels.
One specific general discussion topic is whether monitoring should happen where there is little human impact (to understand a system that has not been degraded by humans), where there is human impact (so the effects from humans can be investigated), or where there is data deserts and little is known about the habitats' and communities' response ...
