Potassium Fertilization on Maize under Different Production Practices in the North China Plain (2011, background): “…has dramatically increased grain production in developing countries, but yield records in the dominant food-producing regions indicate a large gap between the current and potential yields for maize (Neumann et al., 2010), which is an important crop because it contributes to food security in China.”
Indirect Land Use Change From Increased Biofuels Demand - Comparison of Models and Results for Marginal Biofuels Production from Different Feedstocks (2010, background): “However, the yield gap (difference between potential and actual yield) tends to be larger in remote areas with low population density (Neumann et al., 2010).”
Global food demand and the sustainable intensification of agriculture (2011, background): “Yield increases in poorer nations will require significant investments in innovative adaptation of technologies to new soil types, climates, and pests (29, 30) as well as new infrastructure (2).”
Solutions for a cultivated planet (2011, background): “Recent analyses 57,58 have found large yield variations across the world, even among regions with similar growing conditions, suggesting the existence of ‘yield gaps’ (Supplementary Fig.”
Lost food, wasted resources: global food supply chain losses and their impacts on freshwater, cropland, and fertiliser use. (2012, background): “, 2011; Siebert and Döll, 2010) and reducing yield gaps (Licker et al., 2010; Neumann et al., 2010).”
Drivers of changes in agricultural intensity in Europe (2016, background): “Global grain yields in the year 2000 were higher in areas closer to optimal temperature and higher precipitation, while higher efficiencies in grain production were related to higher fertiliser application, the presence of irrigation, market influence, and better accessibility (Neumann et al., 2010)”
The meat of the global food crisis (2013, background): “Such depictions of an asymmetrically under-yielding planet with a ‘yield gap’ (Neumann et al. 2010) must be replaced, I argue, with the recognition that enormous volumes of grains and oilseeds are being inefficiently cycled through concentrated livestock to serve an asymmetrically ‘meaty’ planet, a…”
Exploring SSP land-use dynamics using the IMAGE model: Regional and gridded scenarios of land-use change and land-based climate change mitigation (2018, unknown): “Large yield gaps exist in Sub-Saharan Africa with potential for increased production (Neumann et al., 2010; Van Ittersum et al., 2013; Mueller et al., 2012).”
Yield Trends Are Insufficient to Double Global Crop Production by 2050 (2013, background): “However, opportunities do exist to increase production through more efficient use of current arable lands [4] and increasing yield growth rates by spreading best management practices and closing yield gaps under different management regimes [38–42] across the globe.”
The Global Supply and Demand for Agricultural Land in 2050: A Perfect Storm in the Making? AAEA Presidential Address (2010, background): “Neumann et al. (2010) also find that market influence and irrigation are critical constraints in Central America and South Asian maize production.”
Climate impact and adaptation to heat and drought stress of regional and global wheat production (2021, background): “However, these areas have a large improvement potential due to a large yield gap between current and attainable yields (Neumann et al 2010, Mueller et al 2012).”
Forecasting technological change in agriculture—An endogenous implementation in a global land use model (2014, background): “The main advantage in this context over other measures, like the yield gap analysis [55], is that any yield increase due to improved technology will be reflected by an increase in τ , but may be at least partially undetected by the yield gap, as the potential yield rises as well and the gap remains ”

Greedy or needy? Land use and climate impacts of food in 2050 under different livestock futures (2017, background): “…parts of Africa, Asia, Latin America and East Europe current yields for many crops are only half or less of potential yields (Licker et al., 2010; Neumann et al., 2010; Pradhan et al., 2015) because of factors such as poor soil quality, yield losses due to pests, diseases, weeds and poor access…”
