A Meta Analysis on Farm-Level Costs and Benefits of GM Crops (2011, unknown): “Increases over time in maize yields were expected, at least for most of the developed world [3,37].”
Evidence of slowing yield growth – the example of Swiss cereal yields (2010, result): “These estimates are consistent with annual yield growth in Germany estimated by Krause (2007): 126 kg/year for maize and 99 kg/year for wheat. But our estimates are much higher than trends estimated by Hafner (2003) on a global scale: 62 kg/year and 43 kg/year for maize and wheat, respectively. We f”
Impacts of Europe's changing climate – 2008 indicator based assessment (2009, background): “The impacts of medium and long-term climate change on agriculture and forestry are often difficult to analyse separately from non-climate influences related to the management of the resources (Hafner, 2003).”
The Effect of Soil Erosion on Europe’s Crop Yields (2007, background): “Some scientists claim that trends will continue to boost yield growth at similar rates to those of the past (Ewert and others 2007), whereas others conclude that yield increases will slow due to biophysical constraints on plant productivity (Kindal and Pimentel 1994; Amthor 1998; Hafner 2003).”
Yield Trends Are Insufficient to Double Global Crop Production by 2050 (2013, background): “Many previous studies have shown that crop yields change linearly and have used linear regression to project future crop yields [24–30].”
Global patterns of agricultural land‐use intensity and vertebrate diversity (2015, methodology): “, 2008), because together, they represent approximately 85% of global cereal production (Hafner, 2003).”
Future scenarios of European agricultural land use: I. Estimating changes in crop productivity (2005, background): “Some reports suggest that yields are approaching a ceiling (Calderini and Slafer, 1998) while others found little sign of a slowing down in yield trends for most countries (Hafner, 2003).”
Future cereal production in China: The interaction of climate change, water availability and socio-economic scenarios (2009, background): “Such changes are extremely difficult to quantify and project (Hafner, 2003) and so our scenario should be treated as illustrative.”
