Cross-cutting
Complexity as an opportunity• Different tools for different scales (local, international, global)• Different tools / approaches for different land types / areas• Different tools / instruments / approaches for different places,
cultures, people
• Need to think across temporal and spatial scales and actively seek resilient integrational outcomes
Complexity is both the biggest obstacle but also the biggest opportunity for bioenergy. Do we have the human ingenuity to make it work?
Key cross-cutting questions
Important questions that need to be addressed by research and which are indicative of the complex interactions between bioenergy and food production include: • What is the potential for diversifying value streams, market substitutions,
implicit investment risks and the interactions with food production?• How can the integration of biofuels within food supply systems affect food
security?• The global food system needs to respond to climate change through both
mitigation and adaptation; what are the implications of significant levels of bioenergy deployment on these response options?
• What role do productivity improvements play in creating stronger synergies?
• Can bioenergy be deployed in ways that enhances rather than degrades the resilience of the global food (production and consumption) system? If so, how can this be achieved and how likely is it that good outcomes will arise?
Key cross-cutting questions
In this topical theme, we raise a number of important questions that need to be addressed by research and which are indicative of the complex interactions between bioenergy and food production including: • How can the integration of biofuels within food supply systems affect
food security?• What role do productivity improvements play in creating stronger
synergies?• Can bioenergy be deployed in ways that enhances rather than degrades
the resilience of the global food (production and consumption) system? If so, how can this be achieved and how likely is it that good outcomes will arise?
Key cross-cutting questions: Economic
• Will biofuels be competitive with conventional energy sources?• Set a global price ceiling e.g. for oil / other
renewables? (see Foster, 2014)• Will biofuels compete with food production?
• What is the potential for diversifying value streams, market substitutions, implicit investment risks and the interactions with food production?
• Impacts on input prices?• Floor price for commodity crops?• Impacts on crop yields? • Land demand & rents?
• Impacts on food price volatility
Key cross-cutting questions: Environmental
• Climate change- mitigation and adaptation• Impacts on water
• Availability• Quality• hydrology,
• Impacts on land and soils• land use change• erosion, • soil organic matter, • biodiversity, • carbon stocks, • nutrient and water holding capacities• toxicity (e.g. ash disposal)
• Air quality• Invasive species• GMOs• … many more ….
DeliveringPublic goods• Can perennial crops be
deployed to deliver public goods
• Satellite view of sediment plumes during winter / spring flooding in UK (April/May 2014)
• September 2014 – driest September on record
Key cross-cutting questions: Social & Governance
• Impacts on jobs / job quality• Rural development vs urbanisation
• Impacts on literacy and schooling• Health & welfare• Governance and regulation
• Assurance and certification• Monitoring and measurement• Climate smart agriculture• Issues of scale (production, conversion, national to
global market share)• Sustainable development goals (equity, aspiration)
• Issues of ‘scale’

Integrated systems perspectives
Dynamics of bioenergy, residues and wastes in the global calculator model
Land, Food and Bioenergy Interactions – driver tree
The Global Calculator
Food demand is always provided for in the global calculator model
Level 1: Mismanaged land use. It assumes that 10% more agricultural land would be necessary to attain the selected food/livestock/bioenergy productions.
Level 2: Current world pattern of agricultural system stabilised until 2050 (no change from 2011).
Level 3: 10% less agricultural land is necessary to attain the selected food/livestock/bioenergy productions.
Level 4: 30% less agricultural land would be necessary to attend the selected food/livestock/bioenergy productions.
Land-use efficiency (land integration)
Level 1: Assumes no increase in the production and collection of on-farm residues; and no increase in
the production of post-farm wastes and residues, but with a low increase in their collection for energy
and feed.
Level 2: Moderate increase in the collection of on-farm residues. It also assumes a reduction in the
production of post-farm residues and wastes and moderate increase in collection for energy and feed.
Level 3: High collection of on-farm residues for energy and feed, as well as reduction in the production
of post-farm wastes and residues, and increase in their collection.
Level 4: Extreme collection of on-farm residues for energy and feed, as well as substantial reduction in
the production of post-farm wastes and residues, and increase in their collection.
Wastes and Residues
Summary• Understanding, monitoring and managing complex,
highly interlinked systems- perfect outcomes are extremely unlikely– Beware over-regulation– Life Cycle Assessment (attributional and consequential) is
still a young ‘science’
• Assigning causality for impacts and allocating to co-products
• Beware of burden shifting / gaming• Rewarding ‘co-benefits’ of integration, including
enhanced resilience

‘Political tensions and high prices from Gazprom are driving shifts that suggest Moscow does not hold all the cards
Pressure points: a worker on the Nord Stream project supplying Russian gas to GermanyThe night shift at Agropolychim, Bulgaria’s biggest fertiliser plant, received a fax at 4.30am on January 6 2009 warning that their gas supply was going to be cut off immediately. The engineers demanded four more hours: an instant shutdown would leave a cocktail of explosive chemicals to congeal in the plant’s pipes, destroying vital equipment. “It was all hands on deck,” recalls Philippe Rombaut.…Mr Rombaut’s plans at Agropolychim show that Moscow does not hold all the cards. Next year, he will switch from gas to biomass, running on straw and woodchips. That is highly significant for Gazprom because Agropolychim and Neochim, Bulgaria’s leading fertiliser plants, jointly consume about 25 per cent of the country’s gas.’
