Climate change is already occurring and is driving catastrophic changes in many regions including more frequent droughts. The ability to preserve agriculture and food security in arid regions is challenged by the need to find and recover water from a variety of sources, including groundwater and residual moisture in the air, while maintaining a minimal carbon footprint. Greenhouse agriculture can be practiced in a manner that reduces the overall water and carbon footprint for the crop growth. This requires innovative desalination schemes and the use of water vapor capture where possible. This session will discuss various strategies for water production and water capture to preserve agriculture in arid conditions.
