In order to secure the demand for food and biomass by a growing population, the production of biomass needs to double by 2050. Recent studies agree that better crop management on today’s cropland could increase biomass production by only about 60% (Bruinsma 2011, Tilman et al. 2011). This may be achieved by, for instance, expanding cropland, changing diets, adopting more efficient agricultural practices, or by using current cropland areas more intensively. This choice involves trade-offs. For instance, expanding cropland into non-agricultural ecosystems may reduce other ecosystem services such as biodiversity, and release greenhouse gases. Therefore, intensifying the use of current cropland areas may be a preferred option. In fact, current studies are able to identify regions where there is a capacity to intensify agricultural production (Zabel et al. 2014). Measures aimed at closing the gap between production possibilities and current production, however, are not sufficiently addressed.
