One-third of the world's population lives in water-stressed regions and drinkable water reservoirs are further shrinking due to desalination and pollution. Today, many countries import their water. According to a recent UN report, water shortages could affect 5 billion people by 2050. A potential solution to the world's water shortage might be harvesting water from the air. Earth’s atmosphere always contains tons of water vapor immediately ready to harvest. Cost-effective water harvesting from the air could offer off-the-grid water access in arid regions. However, conventional techniques such as fog harvesting meshes or direct cooling below its dew point with harvesting devices require high relative humidity. The number of months with adequate average humidity (&gt;60%) for water harvesting through direct cooling is limited in many places. Therefore, the development of advanced materials with high water uptake capacity under low relative humidity is critical. This presentation will focus on the development of solid crystalline sorbents known as metal-organic frameworks which are composed of organic linker and metal ions for harvesting water from air with low humidity.
