Climate change impacts on agriculture in 2050 under a range of plausible socioeconomic and emissions scenarios (2015, background): “The CO2 effect is still very uncertain owing to many complex interaction mechanisms, and is widely discussed in the research community (Long et al 2006, Tubiello et al 2007, Wang et al 2012, Boote et al 2013).”
Climate change effects on pasture systems in south-eastern Australia (2009, methodology): “…increases simulated at 550 ppm CO2 were higher than the biomass multipliers used in crop models such as DSSATCERES and EPIC/CropSyst [i.e. 11–19% for C3 species and 4–8% for C4 species (Tubiello et al. 2007)], but the magnitude of the difference between responses for C3 and C4 species was similar.”
Global potential to increase crop production through water management in rainfed agriculture (2009, background): “…(Parry et al 2004, Lobell and Field 2007, Battisti and Naylor 2009), direct effects of elevated CO2 upon plants will probably increase production (Tubiello and Ewert 2002, Challinor and Wheeler 2008), albeit the magnitude of this effect is debatable (Long et al 2006, Tubiello et al 2007).”
Implications of climate change for agricultural productivity in the early twenty-first century (2010, neutral): “B (2010) (Tubiello et al. 2007).”
Climate Change, Agriculture and Food Security in Tanzania (2012, neutral): “At the same time, however, the validity of FACE results has been questioned (Tubiello et al, 2007).”
The Agricultural Policy Environmental EXtender (APEX) Model: An Emerging Tool for Landscape and Watershed Environmental Analyses (2009, background): “There is also a need to investigate further the response of CO2 on crop yield in general in APEX and related models, per the debate that has emerged between Long et al. (2006) and Tubiello et al. (2007).”
Adaptation to climate change through the choice of cropping system and sowing date in sub-Saharan Africa (2013, positive): “…at 370 ppm. Increasing atmospheric CO 2 concentrations can increase the productivity of plants (especially C3 plants), but the effectiveness on increasing crop yields is uncertain (Long et al., 2006; Tubiello et al., 2007) and does require adaptation in management (Ainsworth and Long, 2005).”
The impact of population growth and climate change on food security in Africa: looking ahead to 2050 (2017, background): “It should also be noted that there is debate regarding the beneficial effects of CO2 fertilization on crops (Long, Ainsworth, Leakey, Nosberger, & Ort, 2006; Tubiello et al., 2007) and thus, the mediating effect it has in this study is highly uncertain.”
Adaptation of maize production to climate change in North China Plain: Quantify the relative contributions of adaptation options (2010, background): “…assessment of the climate change mpacts on agricultural production should take comprehensively nto account available adaptation strategies (Reidsma et al., 2010), nd account for the uncertainties from many physical, biological, nd social-economic processes (Tubiello et al., 2007; Tao et al., 009a).”
