Brief history of agricultural systems modeling (2017, positive): “This work has led various modeling groups to develop models that represent CO 2 , water, and GHG ﬂ uxes and also crop growth and yield of grid-cell areas (e.g., Fischer et al. 1995; Rosenzweig et al., 2013b; Elliott et al., 2014a, 2014b).”
A Ricardian Analysis of the Impact of Climate Change on European Agriculture (2016, neutral): “As both agronomic and economic studies have previously shown, irrigation increases the tolerance of plants to higher temperatures (Mendelsohn and Dinar 2003; Elliott et al. 2014; Nendel et al. 2014).”
Climate Change Impacts and Adaptation Strategies of Agriculture in Mediterranean-Climate Regions (MCRs) (2019, background): “Over 80% of the agricultural production in the Mediterranean basin comes from irrigated areas, and this is why it is essential to improve irrigation efficiency to continue satisfying the future demand for food [98,99].”
Assessing agricultural risks of climate change in the 21st century in a global gridded crop model intercomparison (2013, background): “Related studies in this special issue focus on crop water demand and the freshwater supply for irrigation (14), the application of the crop model results as part of wider intersectoral analyses (15), and the integration of crop-climate impact assessments with agro-economic models (16).”
The role of international trade in managing food security risks from climate change (2015, methodology): “The recent assessments of the potential impacts of climate change on crop yields worldwide, which are used in this study, are also based on SSP 2 projections (Elliott et al. 2014; Müller and Robertson 2014; Nelson et al. 2014; Rosenzweig et al. 2014).”
Biostimulants Application in Horticultural Crops under Abiotic Stress Conditions (2019, background): “Scientists generally agree with the perspective that several regions could become arid due to the negative impacts of global climate change on water resources [183].”
Adapting agriculture to climate change via sustainable irrigation: biophysical potentials and feedbacks (2022, background): “By the end of the century, freshwater limitations could require the reversal of 60 million hectares from irrigated to rainfed [79].”
The vulnerabilities of agricultural land and food production to future water scarcity (2019, background): “…the amount of irrigated land must be coupled to crop yield improvement (Liu et al., 2017; Grafton et al., 2017), improvements in crop water use efficiencies and nutrient management to reduce the environmental impacts associated with agriculture (Elliott et al., 2014; Mueller et al., 2012b).”
Global synthesis of drought effects on cereal, legume, tuber and root crops production: A review (2017, background): “…China and South Asia as well as western United States (US) due to projected freshwater limitations by the end of the century could translate in the loss of 600 to 2,900 Petacalories (Pcal) of food production (equivalent to 8-43% of present day total production) (Elliott et al., 2014).”
Addressing future trade-offs between biodiversity and cropland expansion to improve food security (2016, background): “We assume that irrigated areas globally remain constant until 2040, since adequate spatial data on possible future extend of irrigated areas do not exist, although it is likely that freshwater availability for irrigation could be limited in some regions, while in other regions surplus water supply c”
Global water resources affected by human interventions and climate change (2013, background): “Possible reasons for this lie in the different representation of agricultural land and agrohydrological processes in the models (20).”
