Air moisture harvesting technologies are effective in combating desertification by providing additional water sources in arid regions, enhancing agricultural productivity, and supporting sustainable land management practices. These technologies, such as fog nets and atmospheric water generators, can capture moisture from the air, making them valuable in areas with limited rainfall. However, their effectiveness can vary based on local climatic conditions, and successful implementation often requires community involvement and integration with traditional practices.
The disillusioning answer is: not really. :'(
Desertification usually occurs in arid geographical zones, where the atmospheric moisture content is low by definition. That small amount, if collected, may be enough to provide drinking water for humans. But it is necessarily insufficient to sustain a green vegetation, that requires several orders of magnitude more water.
The lucky exceptions are immediate coastal areas, where you might be able to collect some extra moisture from above the sea.
