“…By virtue of being able to fix most of their carbon dioxide from the atmosphere at night rather than during the day time, CAM plants typically show high water‐use efficiency and can survive in environments with high daily temperatures and relatively limited water availability (Cushman, 2001 ; Lüttge, 2010 ; Osmond, 1978 ; Winter, 1985 ; Winter & Smith, 1996 ). The environmental resilience of these plants makes them attractive species for cultivation on marginal land for a variety of potential uses, such as fodder, bioethanol production, or as feedstock for anaerobic digestion (Acharya et al, 2019 ; Borland et al, 2009 ; Davis et al, 2011 ; Hastilestari et al, 2013 ; Holtum et al, 2011 ; Loke et al, 2011 ; Mason et al, 2015 ; Mwine et al, 2013 ; Yan et al, 2011 ). Such crops may be of particular value in semi‐arid regions most likely to experience increased drought risk (e.g., Marthews et al, 2019 ; Otto et al, 2018 ).…”
