Bioenergy Workshop Eberswalde Project „Feeding and fuelling the world 2050“ Goals: –Understanding the interrelations between diet patterns, agriculture, bioenergy and climate change. (Deforestation was not considered!) –Exploring the possibilities to meet global food demand in 2050 under different assumptions on Dietary patterns Expansion of cropland Changes in land use intensity/agricultural yields Changes in intensity and efficiency of livestock production systems Climate change –Quantification of bioenergy potentials in 2050 We acknowledge the funding of this research by: FWF – Austrian Science Fund, Compassion in World Farming, Friends of the Earth, UK

Bioenergy Workshop Eberswalde Calculation of Bioenergy Potential (Primary biomass!) Bioenergy from cropland: –In case „free“ cropland is available: Bioenergypotential = potential aboveground NPP. –In case the demand for crop products exceeds supply by less than 5%: „negativ“ bioenergy potential is subtracted from the potential available on grassland. Bioenergy from grassland: –Best grassland (category 1 out of four) is used more intensively. –Grassland area in category 1 which becomes available by this measure is used for bioenergy production (aboveground NPP of act. vegetation). Bioenergy from crops residues: –Requirements for feeding livestock and bedding are subtracted from available production. –50% of the reminder can be used for bioenergy production

Bioenergy Workshop Eberswalde Conclusions Feeding a growing world population is possible with ecologically sound agricultural production – but only at a modest increase of the share of animal products in human diet. Dietary patterns matter: An increase in the share of animal products in human diets has far reaching implications: –Need to intensify land use (yield increases, feeding efficiency) –Expansion of cropland –Bioenergy potential reduced Food security and bioenergy are possible without further deforestation. Bioenergy and globalisation: Largest bioenergy potentials in Subsaharan Africa and Latin America. Climate matters: Bioenergy potential strongly depends on diet patterns and climate impacts. The later are only poorly understood.
