There already exist devices that can capture atmospheric water (moisture/humidity) and phase change it into liquid water for irrigation purposes. It increasingly is becoming evident that all or parts of presently fertile land will become arid due to 'climate change'. In increasingly drought stricken areas, this existing atmospheric air-conditioning device paradigm could be taken further. The proposal would be to genetically or mechanically engineer trees (flora) to capture water from the air via leaves and transpire the moisture out through the roots. This technology of capturing water from the air is increasingly being deployed in arid regions of the world, why not think of how to get plants to do this? This way, plants would actually irrigate the soil by capturing moisture from the air and transpiring it out through their roots. In this scenario, there does not - a priori - seem a need to irrigate the soil because the moisture is available to the plant via the atmosphere. However, osmotic equilibrium must be maintained by transpiring water through the roots. If the rate of water transpiration (through the roots into the soil) is greater than its rate of evaporation from the soil, the water will eventually be able to cause an increase in the water table of the land thereby restoring fecundity to the land as well as providing (potentially) inexhaustible fresh water sources for people.
