Successive civilizations harnessed the resources available in deserts for millennia, from mining to harnessing water supplies from springs into irrigation to grow crops, and stone, deserts have generally been seen as a resource. In addition, the development of irrigated water has led to high levels of salt in the soil due to drainage issues. In summer, they adorn a whitish or sandy beige-colored coat which .

If this is true, then it is far older than the Namib which has a confirmed 43-million-year history. As with anaerobic conditions of wetlands where organic material is cut off from microbes, such material survives in deserts due to the lack of moisture and bacteria that can eventually break it down.

Y Combinator called filling 1.7 million acres of arid land with 2-meter-deep pools of water the largest infrastructure project ever undertaken. Just to pump ocean water inland and desalinate it would require an electrical grid far greater than the one Earth now devotes to all other uses. If the rains fail it can cause drought. More than 75 percent of Earth's land area is already degraded, according to the European Commission's World Atlas of Desertification, and more than 90 percent could become degraded by 2050. The average rainfall is just that. The area naturally experiences alternating wet and dry seasons. As discussed above, they naturally develop oil and precious metals and gem resources through their unique geology. The scientists collated. Jama'at Nusrat al-Islam wal Muslimeen (JNIM) constitutes an evolving threat in the Sahel region. Environment Deserts Threatened by Climate Change Invasive species thrive with increased carbon dioxide, raising fire risk 2 Nov 2000 By Deborah Hill Desert plants go wild during wet years when treated to excess carbon dioxide, researchers say. "The absolute number of farmers in these [at-risk rural] regions is so large that even simple and inexpensive interventions can have regional impacts," write the authors of the World Atlas of Desertification, noting that more than 80 percent of the world's farms are managed by individual households, primarily in Africa and Asia.
