The phenomenon of desertification occurs mostly in arid and semi-arid regions, but the fertile lands are also vulnerable to the problem of desertification as a result of their exposure to natural and human factors.</p><p style=";text-align:left;direction:ltr"></p><h3 style=";text-align:left;direction:ltr"> <strong>Desertification rate in the Arab world and the world:</strong></h3><p style=";text-align:left;direction:ltr"></p><p style=";text-align:left;direction:ltr"> Here are the following statistics on <strong>the phenomenon of desertification and the rate of desertification</strong> in the world according to the Environmental Protection Law and other sources:</p><p style=";text-align:left;direction:ltr"></p><p style=";text-align:left;direction:ltr"> <strong>Percentage of dry lands in the world:</strong> approximately 40% of the world&#39;s surface.</p><p style=";text-align:left;direction:ltr"></p><p style=";text-align:left;direction:ltr"> <strong>Deserts area in the world:</strong> Deserts cover nearly a fifth of the Earth&#39;s surface.
