“…Based on their scenario analysis of global implications of biomass and biofuel use in Germany, Bringezu et al (2009) came to a similar conclusion. They found that Germany alone, already being a net importer of agricultural land, would require a net additional land area of 2.5-3.4 Mha by 2030, mainly driven by current policy targets on biofuel.…”

The increasing demand for biomass for the production of bioenergy is generating land-use conflicts. These conflicts might be solved through spatial segregation of food/feed and energy producing areas by continuing producing food on established and productive agricultural land while growing dedicated energy crops on so called "surplus" land. Ambiguity in the definition and characterization of surplus land as well as uncertainty in assessments of land availability and of future bioenergy potentials is causing confusion about the prospects and the environmental and socio-economic implications of bioenergy development in those areas. The high level of uncertainty is due to environmental, economic and social constraints not yet taken into account and to the potentials offered by those novel crops and their production methods not being fully exploited. This paper provides a scientific background in support of a reassessment of land available for bioenergy production by clarifying the terminology, identifying constraints and options for ReseARCh ARtiCle BioRisk A peer-reviewed open-access journalJens Dauber et al. / BioRisk 7: 5-50 (2012) 6 an efficient bioenergy-use of surplus land and providing policy recommendations for resolving conflicting land-use demands. A serious approach to factoring in the constraints, combined with creativity in utilizing the options provided, in our opinion, would lead to a more sustainable and efficient development of the bioenergy sector. Unless the sustainability challenge is mastered, the interdependent policy objectives of mitigating climate change, obtaining independence from fossil fuels, feeding and fuelling a growing human world population and maintaining biodiversity and ecosystem services will not be met. Despite the advanced developments of bioenergy, we still see regional solutions for designing and establishing sustainable bioenergy production systems with optimized production resulting in social, economic and ecological benefits. Where bioenergy production has been identified as the most suitable option to overcome the given problems of energy security and climate change mitigation, we need to determine which bioenergy cultivation systems are most suitable for the respective types of surplus land, by taking into account issues such as yields, inputs and costs, as well as potential environmental and socio-economic impacts.

Many studies consider this by allocating land areas to joint products in relation to their weight (Bringezu et al, 2009), energy content (Kastner et al, 2011b), carbon content (Kastner et al, 2011a) or value shares (Prieler et al, 2013;Statistisches Bundesamt, 2013). Furthermore, the protein content was discussed by Kastner et al (2011b) as another weighting scheme for allocation.…”

“…The largest net importers are Japan, Italy, Germany, South Korea, China and Indonesia [108] (Table 4b). For example, Germany alone, with current policy on biofuel importation, will require an additional 2.5-3.4 Mha of cropland by 2030, possibly through land use conversions in Brazil or Indonesia [109]. This in turn will result in an additional 23-37 Tg of CO 2 .…”

This paper presents an exhaustive review of global croplands and their water use, for the end of last millennium, mapped using remote sensing and non-remote sensing approaches by world's leading researchers on the subject. A comparison at country scale of global cropland area estimated by these studies had a high R 2 -value of 0.89-0. of blue water and the rest from rain that falls over irrigated croplands). However, 1.6 to 2.5 times the blue water required by irrigated croplands is actually withdrawn from reservoirs or pumping of ground water, suggesting an irrigation efficiency of only between 40-62 percent. The weaknesses, trends, and future directions to precisely estimate the
