A reassessment of global bioenergy potential in 2050 (2015, background): “Given more moderate expectations for meat consumption and for yield growth in food crops, it is clear that cropland must continue expanding to meet the needs of the world’s population (FAO, 2003; Balmford et al., 2005; Bruinsma, 2009; Wirsenius et al., 2010).”
Biomass use, production, feed efficiencies, and greenhouse gas emissions from global livestock systems (2013, neutral): “(15) and the higher figures from Bouwman et al.”
Livestock: On our plates or eating at our table? A new analysis of the feed/food debate (2017, methodology): “, 2013) and impact of improvements in feed conversion ratios on land-use (Wirsenius et al., 2010).”
How Circular is the Global Economy?: An Assessment of Material Flows, Waste Production, and Recycling in the European Union and the World in 2005 (2015, background): “A change in dietary patterns toward a lower share of animal products and within animal products toward meat from monogastrics, which have a much higher feed-use efficiency than ruminants, would significantly improve the biomass efficiency of the food system (see Herrero et al. 2013; Wirsenius et al.”
Agricultural productivity and greenhouse gas emissions: trade-offs or synergies between mitigation and food security? (2013, background): “On the livestock side, feed productivity increase is generally perceived as the most effective mitigation option [11], as add-on technologies (anti-methanogens, digesters) can only achieve limited levels of abatement [12].”
Drivers for global agricultural land use change: The nexus of diet, population, yield and bioenergy (2015, background): “But, the entire food-chain 39 including animal products and dietary changes have received less attention 40 (Wirsenius et al., 2010), although more recently the need for food demand 41 management has been suggested (Bajželj et al., 2014; Tilman and Clark, 2014).”
Global land use change, economic globalization, and the looming land scarcity (2011, neutral): “The actual amount will depend on future diets, food wastages, and food-to-feed efficiency in animal production (13).”
Feed conversion efficiency in aquaculture: do we measure it correctly? (2018, background): “Growing evidence supports dietary shifts toward more efficient types of animal protein and plant-based foods [2, 4, 6, 7, 21].”
Enhancing the sustainability of commodity supply chains in tropical forest and agricultural landscapes (2013, background): “These trends will put greater pressure on remaining forested areas (Nelson et al., 2010; Wirsenius et al., 2010) releasing forest carbon and thereby increasing the role of agriculture as a driver of climate change.”
Redefining agricultural yields: from tonnes to people nourished per hectare (2013, background): “Increasing demand for meat and dairy is also of importance to the global environment because their production requires more land and other resources than plant-based foods [8–10].”
Greedy or needy? Land use and climate impacts of food in 2050 under different livestock futures (2017, background): “…of animal products, through transitioning to alternatives with lower impact – variously or including poultry (Hoolohan et al., 2013), aquaculture (Roberts et al., 2015), artificial meat/milk (Post, 2012) or plant-based protein (Popp et al., 2010; Stehfest et al., 2009; Wirsenius et al., 2010.”
Investment Needs to Achieve the Sustainable Development Goals Understanding the Billions and Trillions (2015, methodology): “41 Investment needs for adaptation from World Bank (2010) are rebased from $2005 to $2013 and added to the overall range, resulting in a total of $69 – 89 billion per year.”
The future of food — Scenarios and the effect on natural resource use in agriculture in 2050 (2014, methodology): “Economically available amounts of harvest by-products, processing by-products and non-eaten food, all used as feed, were assumed to be limited to 50% of the produced total (a methodology also applied in (Wirsenius et al., 2010)).”
Shifting Diets for a Sustainable Food Future (2016, background): “Wirsenius et al. (2010) estimate that only 1 percent of gross cattle feed energy is converted into human-edible calories.”
Reducing meat consumption in developed and transition countries to counter climate change and biodiversity loss: a review of influence factors (2017, background): “To increase yields without further expansion of land use, high levels of fertilisers and pesticides are used (Cassman 1999; Tilman et al. 2002;Wirsenius et al. 2010).”
