• Exploring SSP land-use dynamics using the IMAGE model: Regional and gridded scenarios of land-use change and land-based climate change mitigation (2018, unknown): “A more detailed representation of the di ff erent components responsible for yield increases (Fischer et al., 2014) is required to improve long-term projections.”
• Trade-offs between environment and livelihoods: Bridging the global land use and food security discussions (2017, unknown): “Currently, yields in the major irrigated wheat, rice, and maize systems in developed countries reach ~80% of the potential, but average yields in developing countries, in particular in rainfed systems are commonly 50% or less of yield potential (Lobell et al. 2009, Fischer et al. 2014).”
• Climate change adaptation in crop production: Beware of illusions (2014, background): “Consider the history of crop yield increases over the past half century, as discussed at length elsewhere (Evans, 1998) (Fischer et al. 2014).”
• Cereal yield gaps across Europe (2018, background): “Fischer et al. (2014) presented a global summary of progress in potential yields, arriving at an average annual progress of 0.61% in wheat.”
• Yield gap analysis of rainfed wheat demonstrates local to global relevance (2016, background): “…substantial global population increases, challenges in adapting to climate change, as well as anticipated changes in diets and consumption patterns by 2050, have raised concerns about food security in the decades ahead (Tilman et al. 2011; Ray et al. 2013; Fischer et al. 2014; Keating et al. 2014).”
• Climate Change Impacts and Adaptation Strategies of Agriculture in Mediterranean-Climate Regions (MCRs) (2019, background): “There is evidence that the increase in temperatures associated with CC may reduce the yield and quality of crops [17,46,47].”
• Break crops and rotations for wheat (2015, background): “Over half of the global wheat production comes from developed countries, and three-quarters is grown in rainfed systems (Fischer et al. 2014).”
• Improved prediction of fungal effector proteins from secretomes with EffectorP 2.0 (2018, background): “Fungal pathogens have been estimated to cause annual crop yield losses of 15-20% and are a major threat to food 28 security (Fischer et al., 2014; Figueroa et al., 2017).”
• The effects of climate extremes on global agricultural yields (2019, background): “Hotspot regions that show strong impacts of climate extremes include: North America for maize, spring wheat and soybeans production, Asia for rice and maize production and Europe for production of spring wheat (table 2, column for indicator B).”
