Presentation on theme: "Bioenergy : managing risks and opportunities"— Presentation transcript:
1 Bioenergy : managing risks and opportunities opportunity to reduce greenhouse gas emissions and provide development benefits (e.g. access to energy; rural development)risk of the world winding up in a zero sum game where one environmental or social problem substitutes for another; largely due to potential competition for increasingly scarce resources, including land and water with impacts on climate change, biodiversity, long-term food security, land rights, etc.a highly complex issue where choices in terms of location, pathways, business models and end uses matterdelivering on the promise requires careful planning and management, based on solid science, both on the national and project levels

3 Bioenergy potential has to be assessed in light of global trends: population growth, nutrition, yieldsGlobal population is expected to grow by 36% between 2000 and 2030 (medium projection of UN/FAO).Average crop yields are expected to increase at about the same rate. However, relative yield increases have in general weakend (estimates for global yields in the next decade predict % p.a. growth for cereals).Meat consumption is expected to increase by 22% per capita between , which requires more cropland for feed.Effects of climate change will put further pressure on yield improvements and availability of arable land.Feeding the world population will require the expansion of global cropland. Additional demand for non-food biomass will add on top of this.Development of global population,agriculture land and consumptionper person in the past ( )Between 2000 and 2030 the global population is expected to grow by 36% (medium projection of UN/FAO). Average crop yields are expected to increase at about the same rate.Between meat consumption is expected to increase by ca. 22% per capita, changing the availability and use of cropland. Average crop yields may not compensate for this increasing demand of animal based food.Feeding the world population will require the expansion of global cropland. Additional demand for non-food biomass will add on top of this.Relative yield increases have in general weakend. Estimates for global yields in the next decade predict that increases for cereals are low with 1-1.1% p.a. growth.It is expected that effects of climate change on agriculture is putting further pressure on yield improvements and arable land.Sources: UN population statistics online; FAOSTAT online3
4 Biofuels may make a difference – life cycle wide GHG emissions vary Life-cycle assessments (LCA) of biofuels show a wide range of net GHG balances compared to traditional fuels, depending on feedstock, conversion technology, and methodological assumptions.Highest GHG savings are for sugar cane (70 to +100%), biogas from manure, and ethanol from residues.Lowest savings, and sometimes even higher GHG emissions than fossil fuels occur when production takes place on converted natural land.Greenhouse gas savings of biofuels compared to fossil fuels4
5 Water - a potentially limiting factor Already water is a scarce resource in many places.Agriculture is already the biggest user of freshwater resources; expanding and intensifying bioenergy production could add to existing pressures.As the integrity of water systems declines, they are less able to provide fundamental ecosystem services such as the provision of clean water, natural filtration services, natural habitat for fisheries etc.Global challenges such as climate change, population growth, change in living standards and energy demand will further impact the world’s water supplies.5

8 Land - a potentially limiting factor Conservative estimates of projected land use for biofuel crops vary between Mha for 2020.Estimates of long-term potential land requirements for biofuels vary widely and depend on the basic assumptions made - mainly type of feedstock, geographical location and level of input and yield increase.Ravindranath et al (2009) estimated that Mha would be required in 2030 to provide 10% of transport fuel demand with 1st gen biofuels. For comparison, total cropland is about 1,500 ha.Land use change has a range of potential implications, including on GHG balance and biodiversity.The drive to meet the demand for palm oil is resulting in conversion of forested areas into palm oil plantations.These satellite images reveal how a combination of transmigration, logging interests, and palm oil plantation development have transformed an area that was previously tropical lowland rain and swamp forest.In particular habitat loss through land use change might have a large impact on biological diversity.Invasive species as feedstocks, and nutrient pollution through intensive agriculture may further impact on biological diversity.Benefits from mitigated climate change can not compensate losses by habitat conversion for decades.However, utilizing recently abandoned and degraded land could lead to beneficial effects for biodiversity.Source:UNEP Atlas One Planet - Many People8
9 Energy TrendsBiofuels provide about 3% of global road transport fuels. In 2011, biodiesel expanded and ethanol production was stable or down slightly compared with in 2010, for the first time in a decade.Gaseous biofuels’ and wood pellets’ quantities are limited but growing; the latter production doubling since 2008.Biofuel mandates open a 220 billion litre market by Ren21 GSR 2012Energy market development.Biofuels - not only for transport!Bioenergy is used in many parts of the world already – but mainly in form of traditional biomass for heating and cooking.This practice comes with impacts on health – indoor air pollution – and deforestation, amongst others.We need to ensure that the 1.4 billion energy poor who are dependent on this practice can move to access to modern energy services. Biofuels can be a stepping stone.Biofuels - only hand in hand with energy efficiency and demand management!WWF Study.2011 record investment in RE.Biofuels – drop in asset finance due to uncertainty over feedstock supplies.R&D for RE on the rise – mostly for solar, followed by advanced biofuels.Global production of fuel ethanol was stable or downslightly in 2011, for the first time since 2000, to anestimated 86.1 billion litres.Biodiesel continued to rise globally.Harvests:2010/11 – Brazil2011/12 – USVulnerability!Policies:Biofuels obligations and mandates in at least 46 countries at national level, and 26 states and provinces.Increasing attention to sustainability standards.Biomass power was the third largest sector for totalrenewable energy investment in 2011, even though itsshare fell 12% to USD 10.6 billion. Asset finance declined. Venture capital, private equity and R&D increased. Ren21 GSR 201Thanks to new technologies by 2050, 32 exajoules of biofuels will be used globally, providing 27% of world transport fuel. IEA Biofuel Roadmap

17 Public perception / outlook Emergence of a more balanced approach to risks and opportunities. Yet, uncertainty in the investor community.Recognition of co-existence of two markets: local use and globally traded commodity.Emergence of integrated systems approach to optimise provisioning services of ecosystems, particularly land and water resources, for food, feed, fuel and fibre.Mandates / targets need to be set based on science and sustainably feasible potentials. They need to be flanked by solid sustainability standards on the project level, and embedded in broader low carbon development strategies.Bioenergy policy planning tools and processes are available and increasingly applied.
