“…Process-level crop models are increasingly used to project climate change impacts on food security (e.g. Ahmad et al, 2020;Chen et al, 2020;Resop et al, 2016;Wang et al, 2020;Xiao et al, 2020). Recent literature uses projections from a single model to estimate the magnitude of such effects on yield and other response variables.…”

“…Rice and wheat have been the most important staple crops in the world, feeding more than 90% of the global population (Fitzgerald et al, 2009; Shewry, 2009). The impacts of climate change on crop yield are already alarming (Asseng et al, 2015; Schleussner et al, 2016; Wang et al, 2020), though crop yields can benefit from elevated atmospheric [CO 2 ] (Ainsworth, 2008; Lv et al, 2020; Wang et al, 2015).…”

Elevated [CO₂] raises the temperature optimum of photosynthesis and thus promotes net photosynthesis of winter wheat and rice

Atmospheric CO2 concentration ([CO2]) has increased by 49% since the pre‐industrial era, and this increase will continue. Photosynthesis has long been recognized as one of the most temperature‐sensitive processes, while far less is known about how elevated [CO2] (e[CO2]) affect crop photosynthesis response to short‐term temperature increase. To reveal the effect, we measured gas exchange of winter wheat and rice with various leaf temperatures (TL) under different [CO2] conditions (ambient, +120 μmol mol−1 in wheat, +160 μmol mol−1 in rice, and +200 μmol mol−1 in both) using open‐top chamber facility. Analysis of the measurements showed that e[CO2] generally increased net photosynthesis (Pn) by 10–40% across various TL at different developmental stages. The temperature sensitivity of Pn was negatively correlated with TL. Elevated [CO2] raised the temperature optimum (Topt) of Pn by 1.8–5.6°C for wheat and 2.2–4.8°C for rice, resulting in a wider range of TL that can promote Pn. The responses of stomatal conductance, the maximum rate of carboxylation and the ratio of intercellular to growth environment [CO2] to Topt are not only crop‐specific but also stage‐dependent. Furthermore, there is a divergence in the relationships between photosynthetic parameters for wheat and rice at Topt. We conclude that e[CO2] raises Topt of leaf photosynthesis and thus promotes Pn of winter wheat and rice in a humid subtropical climate. Further research on the coordination of leaf hydraulic and photosynthetic parameters in upland wheat and irrigated rice, as well as their response to e[CO2] should be made in the context of climate change.

“…However, changes in the potential distribution of crops that typically result from climate change, although widely predicted (Ureta et al 2012;Zabel et al 2014;Shabani and Kotey 2016;Ramirez-Cabral et al 2017;Yue et al 2019), have yet to receive adequate attention from those conducting research on such exposure. Some studies simply simulated the distribution and intensity of extreme weather events within a major growing region (Zhang et al 2018a;Wang et al 2020) to characterize crop exposure, but did not take into account the actual distribution of the particular crops on a spatial scale fine enough for precise quantification. Other studies used gridded global data on crop distribution to examine current and future exposure.…”

Exposure to extreme heat can severely harm crop growth and development, and it is essential to assess such exposure accurately to minimize risks to crop production. However, the actual distribution of crops and its changes have neither been examined in sufficient detail nor integrated into the assessments of exposure to ensure their accuracy. By examining the distribution of maize at a high resolution through species distribution modeling, we assessed the past and future exposure of maize to temperatures above 37°C worldwide. Such exposure is likely to be widespread and severe, mainly in the subtropics, and may even expand to the mid-latitudes to encompass some major maize-producing areas. Many areas at both high and low latitudes may become exposed for the first time in the next 20 years. By the 2050s, the total area exposed could increase by up to 185% to 308.18 million ha, of which the area exposed for over 60 days may increase nearly sevenfold. The average length of exposure may increase by 69% to 27 days, and areas optimally suited to maize planting may see the fastest increase by up to 772%. Extreme heat can threaten global maize production severely, and measures to mitigate that threat and to adapt to it are urgently needed.
