Contents Background Study objectives, framework Preliminary results for feedback Policy and research priorities
Background Energy economy Renewable energy investment Energy deficit and poverty World population and income Human diet energy structure
Biofuels in general Do biofuels matter for the oil industry? Do biofuels matter for agriculture and rural development? Practically all demand for biofuels is from transport Bioethanol is 90% of biofuels production Now, most bioethanol production is from sugar or starch crops (presently sugarcane and maize) In future, most bioethanol production will be “second generation” from cellulose and lignocelluloses processes
Energy economy Fast economic growth, especially in China and India Congruence of demand growth, finite reserves and geo-political uncertainty Past cycles associated with oil peaks, and recent oil prices $ 110+ /barrel National energy security driving policy agendas Local energy underpins sustainable development/MDGs
Projected US maize use for bio-ethanol (doubling 2006-2016)

International market responses world prices of key feedstock crops Note: *Rest of the world. Source: IFPRI IMPACT projections Increase is over the 2020 baseline levels
International market responses livestock commodity price under biofuel scenarios, By 2020 Note: *Rest of the world.
Resource and environment dynamics Biofuels impacts on land, water and greenhouse gases are the three main environment concerns with large scale development of biofuels. If all national policies and plans on biofuels are successfully implemented, 30 million additional hectares of crop land will be needed along with 180 km 3 of additional irrigation water withdrawals. Biofuel impacts on carbon savings and GHGs emission depend on how they are produced.
Potential crop effects Under the different scenarios of biofuel expansion, crop areas and production practices are expected to change, including grain and residue prices, the consumption basket, crop substitutions, land and water use, cultivars selection and field management. While maize and sugarcane dominate bioethanol feedstock use at present, some diversification of bioethanol (and biodiesel) feedstocks is expected by 2030. Moreover, while there are strong pressures for intensification because of the strong demand for cereals, water and nutrient use efficiency is expected to rise as water and fertilizer prices rise relative to grain prices
Some detail: potential crop effects An example maize mixed crop-livestock system in SSA
Pressure points on crop-livestock farming systems Crop competition
Dynamic cropping systems, e.g., Zhejiang, China Crop competition Potential impacts on crop-livestock farming systems
Impacts on livestock By 2015, without crop yield growth an increase in grain prices leads to a reduction in feedgrains -- with greater impacts in more the more intensive crop-livestock systems (e.g., dairy) By 2030, with widespread second generation biofuel production, the focus of competition shifts to biomass – and impacts depend on the cost of harvesting biomass for bioethanol, i.e., economics of bioethanol vs economics of ruminant production. The aggregate effect is likely to be reduction in biomass availability for ruminant fodder. In densely populated systems which lack alternative fodder resources, a reduction in ruminant production is expected or a (further) shift to intensive grain based feeding systems. In pasture-based systems may be less affect unless competition arises from cropping Potential impacts on crop-livestock farming systems
Potential impacts on crop-livestock systems Intensification, diversification
Policy implications and research priorities Policy implications Research priorities
Policy implications Foster widespread use of second generation bioethanol production Reduce, amend, or even eliminate biofuels trade barriers Avoid aggressive biofuel expansion through subsidies which runs ahead of the availability of proven sustainable feedstock and biofuel production technologies Target rate of expansion of biofuels to the particular agricultural resource base and crop-livestock-energy systems as well as available technologies of each country Encourage small and medium size feedstock farmers and also small scale biofuel technologies
Research priorities Life cycle analyses (LCA) Biofuel value chain and local markets study Strategic assessment and targeting Early warning system in hotspots Integrated crop-livestock-energy models Management of crop residues Local innovation and learning Sense-act-observe-adjust
