Zero Net Deforestation and Degradation (ZNDD) means no net forest loss through deforestation and no net decline in forest quality through degradation. Scenario name Description BAU ”Business as usual”: Projection of future development in line with historical trends BE2010 As BAU but the production of bioenergy fixed at the level in 2010 BEPlus Projection of bioenergy demand by 2050 as in the 100 per cent renewable energy vision by the Ecofys Energy Model BEPlusRED As BEPlus but with target ”no net deforestation” (RED=Reducing Emissons from Deforestation) BiodivRED Stricter biodiversity protection combined with target ‘no net deforestation’ Land Use Change – Effect of Adding BE, Biodiv & RED – rel to BAU Cumulative land-use change and net forest cover change (managed + unmanaged forest area) caused by additional bioenergy production under the BiodivRED scenario (compared to the 2010 level of bioenergy production) •Net gain of total forest area due to restriction of deforestation •Protection of biodiversity within pristine and other types at the costs of grassland and savannah (which is mostly located in the southern hemisphere) Regional Effects by Adding BE, Biodiv, RED - Unmanaged Forest rel to BAU Loss of pristine (unmanaged) forest as a proxy for BE production on Biodiversity Cumulative loss of area of Cumulative loss of area of unmanaged forest 2000-2050 in unmanaged forest 2000- different regions under the BAU 2050 in different regions scenario under the BEPlus RED scenario •most of the loss of unmanaged forest •the loss of unmanaged forest is not takes place in the tropical areas of South only considerably smaller but also America, Africa and Asia more evenly distributed from a global perspective GHG Emissions by Scenarios GHG emissions from total land use 2000- 2050 under the different scenarios •Under the BE2010 scenario, the bioenergy use is small compared to the other scenarios, and the GHG emissions are the highest, 8,091 Mt CO2/year. The GHG emissions are lower under the BAU and BEPlus scenarios, where the bioenergy use is more extensive. •Lowest GHG emissions can be achieved under the RED scenarios Agricultural Water Demand by Scenarios Water consumption for agriculture 2000- 2050 under the different scenarios •All scenarios show increased demand •Lowest restriction on forest and biodiversity conservation show less water need •Higher restriction implies less land available for eg food production = intensification EUROPE Case study on Europe IIASA’s BeWhere Model www.iiasa.ac.at/bewhere ?? how much of the EU20-20-20 targets (in terms of renewable energy from biomass) can be reached with forest biomass only ??

Where does it come from (trade?) ? How is it produced ? What share of it is used (thinning/waste etc…) ? Co-benefits (sequestration/balanced or neg. emissions…) ? System boundaries ? Definition of Sustainability ? Land use change and INDIRECT land use change ? Competition for land and for resources (by sector etc.) ? Integrated assessment ?
