Agriculture is mankind's single largest usage of water, comprising 70% of all water usage. Optimizing water usage in agriculture is therefore crucial to ensuring global water security. A greenhouse is quantitatively modeled as a bioreactor and it is shown that the bulk of the water supplied to a conventionally aspirated greenhouse is lost in the form of humidity. This implies that evaporative losses in agriculture comprise a clear majority of mankind's total water consumption. Inlet CO 2 enrichment using existing membrane materials can minimize the air feed rate required to supply adequate CO 2 for photosynthesis, thereby mitigating evaporative losses. © 2018 American Institute of Chemical Engineers AIChE J , 64: 2324–2328, 2018
