The Impact of Genetic Changes during Crop Domestication (2018, background): “The number of plant species used for food by preagricultural human societies is estimated to be around 7000, of which only a tiny fraction were domesticated [11].”
Interspecific Hybridization for Brassica Crop Improvement (2019, background): “Ex situ conservation of plant genetic resources started in the mid-twentieth century, as an initiative to prevent the rapid loss of plant biodiversity resulting from the introduction of improved varieties to replace landraces [182,190,191].”
Interplay of trade and food system resilience: Gains on supply diversity over time at the cost of trade independency (2020, background): “Diverse production of foodstuff (in terms of nutritional components) (RP1a) is considered to positively affect stability and resilience in agricultural ecosystems (Cabell and Oelofse, 2012; Khoury et al., 2014) and this indicator is therefore assumed to contribute positively to resilience.”
Worldwide trends in underweight and obesity from 1990 to 2022: a pooled analysis of 3663 population-representative studies with 222 million children, adolescents, and adults (2024, neutral): “25–29 Furthermore, changes in food processing technology and increasing commercialisation and industrialisation of food 30 have increased the consumption of processed foods, which leads to higher caloric intake and weight gain than fibre-rich foods such as whole grains and fruits.”
The expansion of modern agriculture and global biodiversity decline: An integrated assessment (2016, neutral): “In terms of agricultural biodiversity, Khoury et al. (2014) have documented how global crop production has become less diverse in the last 50 years, in the sense that it has become more dominated by a small number of crops.”
Farm production diversity and dietary quality: linkages and measurement issues (2018, background): “The resulting production increases have contributed considerably to reducing hunger and improving peoples’ access to caloriedense staple foods (Godfray et al. 2010; Khoury et al. 2014; Pingali 2015).”
Genetic diversity is considered important but interpreted narrowly in country reports to the Convention on Biological Diversity: Current actions and indicators are insufficient (2021, neutral): “The first two indicators also likely reflect Aichi Target 13 ’ s emphasis on agricultural species, and the importance of genetic resources for national food security (Esquinas-Alc ´ azar, 2005; Khoury et al., 2014).”
Rethinking Agricultural Trade Relationships in an Era of Globalization (2015, background): “A central factor underlying these patterns may be a global shift in diets toward more energy-dense imported foods (Khoury et al. 2014).”
Nutrition Transition and the Structure of Global Food Demand (2017, neutral): “This hypothesis is also consistent with studies that highlight a convergence of food demand in middle-income countries toward the pattern of demand in high-income countries (Pingali, 2007; Khoury et al., 2014).”
The paradox of productivity: agricultural productivity promotes food system inefficiency (2019, neutral): “Across the world diets have become more similar as eating habits have converged on foods underpinned by the same commodities (Khoury et al., 2014), arising from global agriculture’s bias towards energy-dense commodities rather than nutrient-rich fruits and vegetables (Bahadur et al.”
