A comparative study of some environmental impacts of conventional and organic farming in Australia (2006, background): “Amongst the most prominent impacts of agriculture on the global environment are (Pimentel, 1994; Kendall and Pimentel, 1994): during the past 40 years almost one third of the world s cropland has been abandoned because of erosion and degradation, agriculture accounts for 80% of deforestation, and…”
Trends in maize, rice, and wheat yields for 188 nations over the past 40 years: a prevalence of linear growth (2003, background): “Ecologists, on the other hand, have generally assumed that yield growth is slowing, due to biophysical constraints on plant productivity, and have often presented evidence of a decline based on historical trends (Kendall and Pimentel, 1994; Ko et al., 1998; Hall et al., 2000).”
Bending the Curve: Toward global sustainability (2000, background): “The quantity of land so severely degraded that it is removed from agriculture production has been reported at from 5-10 million hectares per year (Kendall and Pimentel, 1994) though the basis for these estimates is weak and they may be high (Alexandratos, 1995).”
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).”
