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 CO₂ enrichment using existing membrane materials can minimize the air feed rate required to supply adequate CO₂ for photosynthesis, thereby mitigating evaporative losses. © 2018 American Institute of Chemical Engineers AIChE J, 64: 2324–2328, 2018

通过进口二氧化碳富集减少温室用水

农业是人类最大的用水量，占所有用水量的70％。因此，优化农业用水对确保全球水安全至关重要。温室被定量地模拟为生物反应器，并且显示出供应给常规抽吸的温室的大量水以湿度的形式损失。这意味着农业中的蒸发损失占人类总耗水量的绝大部分。使用现有膜材料富集进气口CO ₂可以使为光合作用供应足够的CO ₂所需的空气进料速率最小化，从而减轻蒸发损失。©2018美国化学工程师学会AIChE J，64：2324–2328，2018
