Context for links between Context for links between bioenergy + environmental resourcesbioenergy + environmental resources

• Renewables only 6% of EU-25 energy mix in 2003

• Need to reduce CO2 emissions from energy use

• Bioenergy is very important renewable energy source

• Agriculture has strongest growth potential of the 3 main biomass sources (next to forestry + waste)

• Agricultural land use has a strong impact on water quality and quantity, soils, biodiversity, landscape

How do we combine bioenergy production and the protection of natural resources on farmland?

EEA project: How much biomass can Europe EEA project: How much biomass can Europe produce without harming the environment?produce without harming the environment?

Objective: determine the bioenergy potential from agriculture, forestry, waste in 2010, 2020, 2030, which

- exerts no additional pressure on farmland and forest biodiversity or

soil and water resources

- respects other environmental objectives

6

Model assumptions for calculating the Model assumptions for calculating the agricultural bioenergy potentialagricultural bioenergy potential

• Basic assumption: no competition between bioenergy and production of food for domestic use (maintain food self sufficiency)

• Liberalisation of agricultural markets due to CAP reform

• Significant yield increases for energy crops

• Grow mainly specialised bioenergy crops beyond 2010 (when shift from first to second generation biofuels is assumed), e.g. perennial grasses / SRC

• Policy framework supports environmental orientation of food and energy crop production

Main messages from technical report on agricultural bioenergy potential

• Agricultural bioenergy production is increasing strongly + will rise further

• Environmental risks of bioenergy production are becoming apparent from national evidence

• Conditions for keeping biomass production environmentally-compatible explained

• Underlying modeling described in detail• Discussion of policy options to steer biomass

production in environmental direction• Limited review of policy integration + global issues

Bioenergy work at EEA in 2007

• Technical report on estimating the environmental bioenergy potential from agriculture

• Background paper on biomass production and water protection for WFD conference

• Joint EEA/JRC expert consultation on short rotation coppice + energy grasses (see JRC site: http://re.jrc.ec.europa.eu/biof/

• Developing the most greenhouse gas and energy-efficient bio-energy pathways

• Exploration of links with OECD, IEA + others

Maximising the potential for COMaximising the potential for CO22 savings savings

• Effects on water quantity

• Climate and soil conditions need to influence crop choice

• Need to consider what agriculture systems are being replaced

• What cropping systems to chose: SRC and perennial grasses can impact on groundwater recharge

• Effects on water quality + ecosystems

• Impacts from land use change, e.g. maize replacing grassland..

• How to utilise by-products / review total nutrient cycle

• Management at farm level: crop choices + rotation, fertilisation, planting and harvesting practices

• Impacts of conversion processes (water use, emissions)

Bio-energy cropping – potential Bio-energy cropping – potential synergies with water protectionsynergies with water protection

• Replace annual crops with perennial energy crops

(energy grasses, willow coppice etc)

• Widen crop rotations to benefit soil + nutrient

management (e.g. biomass crop mixes, alfalfa)

• Establish buffer strips with energy crops

• Create flood retention zones by using perennial

energy crops

• Combine waste water treatment and biomass

harvesting

Further Issues in Policy and ResearchFurther Issues in Policy and Research

• Development and implementation of sustainability standards

• Energy policy needs to develop framework conditions for environmentally friendly bioenergy systems

• Need for raising environmental awareness and training of all actors involved

• Climate change complicates the picture - affects ability to make assumptions about the future

• Scale of production

• with a smaller scale it is easier to come up with solutions tailored to local agri-environmental conditions

• Crop rotation and diversification are important factors

• Need more research to enable Life Cycle Assessments of bioenergy crops + bioenergy pathways

Planned EEA activities on bioenergyin 2008 and beyond

• Present work on optimising bioenergy pathways + agricultural potential, establish web (sub)page

• Contribute to OECD/IEA report on biofuels• Analyse approaches to sustainability impact

assessment of biofuels with JRC• Further develop GHG life cycle balances with IEA,

JRC and other global players• Explore ways of linking agro-econ. + environment

models on GHG balance of indirect land use change• Develop an approach to assessing biofuel production

in context of ecosystem services project
