An international team of researchers from Austria (Alpen-Adria Universitat Klagenfurt e Wien e Graz), Germany (Potsdam Institute for Climate Impact Research), and United Kingdom (University of Leeds) attempted to use a biomass balance model to present "integrated food, livestock, agriculture, and bioenergy scenarios for the year 2050, based on a consistent representation of UN-FAO (United Nations Food and Agriculture Organization) projections of future agricultural development".

From the analysis (which follows a "food first" approach), they attempted to estimate the global bioenergy potentials in the year 2050. The analysis covers 11 regions, 10 crop aggregates, 2 livestock aggregates, and 10 food aggregates, incorporating data on land use, global net primary production (NPP), and socioeconomic factors.

Some highlights of the results include: (1) Global bioenergy potentials in 2050 excluding forestry are about 100 EJ/year (1 EJ is on Exajoule, a unit of energy equivalent to 1018 joules); this estimate could increase by 60% if "poorer" diets are chosen; (2) Food and livestock feed requirements strongly influence bioenergy potentials; (3) Food crop yields affect the area available for energy crops; (4) Climate-change impacts on bioenergy potentials may be substantial but are highly uncertain.
