To serve our needs, almost half the planet’s land area has undergone this kind of change, and we have caused extensive land degradation and biodiversity loss. A majority of ecosystem services are being degraded or used unsustainably. Biodiversity loss is of particular concern since the variety of life at the genetic, species, and ecosystem levels is a prerequisite for many of these services, which in turn are essential for sustainability. Our land use provides food and other product s necessary for sustaining the growing human population, so our ‘footprint’ will continue to be large. Further, attractive biomass production systems need to be developed, along with effi  cient technologies for converting biomass to fuels and other bio-based products, in order to replace fossil fuels. Expanded consumption of biomass requires deriving feedstocks from landscape management systems that pro-mote biodiversity and provide a broad range of other ecosystem services.Th e links between land use change (LUC) and the emerging bio economy are the subject of current research eff orts and public debate.

Considering well-documented impacts of forest conversion and cropland expansion into uncultivated areas, such as habitat loss, greenhouse gas emissions, and degradation of soils and water bodies, this viewpoint is substantiated – and developing technologies and systems for using residues and waste as feedstock also helps to address waste manage-ment challenges and contributes to improved resource use effi  ciency. However, the “no-LUC” view ignores the issue that many current land uses are unsustainable. We face the double challenge of addressing the negative impacts of current land use while increasing bio-mass production to support phasing out fossil fuels. Would it not be reasonable to look for synergies between these two objectives? For example, by investigating options for achieving benefi cial LUC with new biomass production systems that are integrated into agricultural and forestry landscapes, mitigat-ing some of the impacts associated with current land use and improving the way we manage land, water, and other essential resources.In many cases, biomass can be produced alongside food and feed, but the promotion of attractive options for expanded biomass production need not be premised on the requirement that current levels of food production in a region be maintained or increased. Cultivating short rotation forests or peren-nial grasses can be a welcome opportunity for land owners who seek to address land use impacts such as soil erosion, compaction, salinization, sedimentation, and eutrophication of surface waters due to excess fertilization.Integrated production systems, including double-cropping and various agroforestry systems, can pro-vide several products from the same land area and in this way increase land productivity and resource use effi  ciency. Feedstock conversion systems can also produce several products, e.g., biofuels together with animal feed that can replace cultivated feed and also reduce grazing requirements. Such integra-tion can, in some instances, help maintain or increase food production in a region. In other instances, reduced food production will be compensated by increased production elsewhere, which need not imply that forests are cut down to make place for agriculture.Last year, the Global Bioenergy Partnership (GBEP) launched a call for examples of positive bioen-ergy and water relationships, inviting scientists and other experts to share results and experiences of how good management of resources, drawing on the complementarity of diff erent systems, can deliver food, materials, and bioenergy whilst improving the state of water. Selections from these examples were presented at a workshop–the seventh in a series of events exploring linkages between bioenergy and water. Th e results also formed the basis for a joint publication by GBEP and IEA Bioenergy1 that presents an encouraging variety of positive bioenergy and water relationships, in terms of both feedstocks and geographical distribution, highlighting the multiple environmental and socio-economic benefi ts of good practices.In a recent workshop organized  by IEA Bioenergy, in collaboration with six other organizations and networks, participants addressed methodological and governance aspects of landscape management and design for food, bioenergy, and the bio-economy, including inspiring examples of initiatives to support stakeholder interaction and identify opportunities.2Many of the examples discussed at these workshops involve constructive stakeholder dialogues on fi nding solutions supported by empirical data and science-based information. Th is is a breath of fresh air compared to some experiences from recent years’ bioenergy debate, which has seen opposing sides appearing to be more interested in craft ing strong messages than in keeping up-to-date with  progress in science and practice. Editorial G Berndes, U Fritsche197© 2016 The Authors. Biofuels, Bioproducts, Biorefining published by Society of Chemical Industry and John Wiley & Sons, Ltd. |  Biofuels, Bioprod. Bioref. 10:195–197 (2016); DOI: 10.1002/bbbIn this issue of BioFPR, Gerd Sparovek and colleagues present an illustrative example in this regard. Based on a structured exchange on land use and nature conservation in Brazil, involving experts associ-ated with major producer interests as well as environmental NGOs, the authors conclude that the major-ity of actions and expected future trends refl ect the balancing of, or the ambition to balance, production and conservation. At the same time, much of public opinion–and in turn decisions in the parliament and government regarding agriculture and conservation–is shaped by a perceived confl ict between these two objectives and by a debate that has become, at least to some extent, an end in itself. Th e expert exchange resulted in a common ground agenda for sustainable agricultural development, but it was also noted that there were many barriers to overcome, not least associated with old and deeply rooted mutu-ally exclusive conceptions and positions.At the upcoming European Biomass Conference & Exhibition (EUBCE 2016) in Amsterdam in June, the workshop ‘Th e world needs more land use change’ will highlight bioenergy as an opportunity to promote more sustainable land use, where participants are invited to share experiences and views on how biomass production can be localized, designed, and managed to support both provisioning and regulating ecosystem services to meet future demand for food, energy, and materials, as well as nature conservation needs. A colleague recently proposed that the acronym iLUC should stand for intelligent land use change.  In this sense, we very much look forward to learning how to achieve far-reaching iLUC whilst promoting further growth of a sustainable bio-based industry.References1.
