Downscaling of agricultural market impacts under bioeconomy development to the regional and the farm level—An example of Baden‐Wuerttemberg

The expansion of the bioeconomy sector will increase the competition for agricultural land regarding biomass production. Furthermore, the particular path of the expansion of the bioeconomy is associated with great uncertainty due to the early stage of technology development and its dependency on political framework conditions. Economic models are suitable tools to identify trade‐offs in agricultural production and address the high uncertainty of the bioeconomy expansion. We present results from the farm model Economic Farm Emission Model of four bioeconomy scenarios in order to evaluate impacts and trade‐offs of different potential bioeconomy developments and the corresponding uncertainty at regional and farm level in Baden‐Wuerttemberg, Germany. The demand‐side effects of the bioeconomy scenarios are based on downscaling European Union level results of a separate model linkage between an agricultural sector and an energy sector model. The general model results show that the expanded use of agricultural land for the bioeconomy sector, especially for the cultivation of perennial biomass crops (PBC), reduces biomass production for established value chains, especially for food and feed. The results also show differences between regions and farm types in Baden‐Wuerttemberg. Fertile arable regions and arable farms profit more from the expanded use of biomass in the bioeconomy than farms that focus on cattle farming. Latter farms use the arable land to produce feed for the cattle, whereas arable farms can expand feedstock production for new value chains. Additionally, less intensive production systems like extensive grassland suffer from economic losses, whereas the competition in fertile regions further increases. Hence, if the extensive production systems are to be preserved, appropriate subsidies must be provided. This emphasizes the relevance of downscaling aggregated model results to higher spatial resolution, even as far as to the decision maker (farm), to identify possible contradicting effects of the bioeconomy as well as policy implications.     

Comparative development of knowledge-based bioeconomy in the European Union and Turkey

Abstract

Biotechnology, defined as the technological application that uses biological systems and living organisms, or their derivatives, to create or modify diverse products or processes, is widely used for healthcare, agricultural and environmental applications. The continuity in industrial applications of biotechnology enables the rise and development of the bioeconomy concept. Bioeconomy, including all applications of biotechnology, is defined as translation of knowledge received from life sciences into new, sustainable, environment friendly and competitive products. With the advanced research and eco-efficient processes in the scope of bioeconomy, more healthy and sustainable life is promised. Knowledge-based bioeconomy with its economic, social and environmental potential has already been brought to the research agendas of European Union (EU) countries. The aim of this study is to summarize the development of knowledge-based bioeconomy in EU countries and to evaluate Turkey’s current situation compared to them. EU-funded biotechnology research projects under FP6 and FP7 and nationally-funded biotechnology projects under The Scientific and Technological Research Council of Turkey (TUBITAK) Academic Research Funding Program Directorate (ARDEB) and Technology and Innovation Funding Programs Directorate (TEYDEB) were examined. In the context of this study, the main research areas and subfields which have been funded, the budget spent and the number of projects funded since 2003 both nationally and EU-wide and the gaps and overlapping topics were analyzed. In consideration of the results, detailed suggestions for Turkey have been proposed. The research results are expected to be used as a roadmap for coordinating the stakeholders of bioeconomy and integrating Turkish Research Areas into European Research Areas.     

High-value oils from plants

The seed oils of domesticated oilseed crops are major agricultural commodities that are used primarily for nutritional applications, but in recent years there has been increasing use of these oils for production of biofuels and chemical feedstocks. This is being driven in part by the rapidly rising costs of petroleum, increased concern about the environmental impact of using fossil oil, and the need to develop renewable domestic sources of fuel and industrial raw materials. There is also a need to develop sustainable sources of nutritionally important fatty acids such as those that are typically derived from fish oil. Plant oils can provide renewable sources of high-value fatty acids for both the chemical and health-related industries. The value and application of an oil are determined largely by its fatty acid composition, and while most vegetable oils contain just five basic fatty acid structures, there is a rich diversity of fatty acids present in nature, many of which have potential usage in industry. In this review, we describe several areas where plant oils can have a significant impact on the emerging bioeconomy and the types of fatty acids that are required in these various applications. We also outline the current understanding of the underlying biochemical and molecular mechanisms of seed oil production, and the challenges and potential in translating this knowledge into the rational design and engineering of crop plants to produce high-value oils in plant seeds.     

Social life cycle assessment: in pursuit of a framework for assessing wood-based products from bioeconomy regions in Germany

Purpose

With many policies in Germany steering towards a bioeconomy, there is a need for analytical tools that assess not only the environmental and economic implications but also the social implications of a transition to a bioeconomy. Wood is expected to become a major biomass resource in bioeconomy regions. Therefore, this paper develops a social life cycle assessment (sLCA) framework that can be applied specifically to a wood-based production system in one of Germany’s bioeconomy regions.

Methods

This paper reviews and analyses existing sLCA approaches, in terms of how applicable they are for assessing a wood-based production system in a German bioeconomy regional context. The analysis is structured according to the standard phases of environmental life cycle assessment (LCA). However, we use the term social effects rather than social impacts, to acknowledge the unknown cause–effect relationship between an organisation’s activities and its social impacts. We also consider the establishment of regional system boundaries, as well as the relationship between the social effects and the product being assessed. Additionally, an approach for the development and selection of social indicators and indices is outlined. Furthermore, we discuss data requirements and present an approach for a social life cycle impact assessment method.

Results and discussion

A new conceptual framework for a context-specific sLCA to assess wood-based products manufactured in a bioeconomy region was developed. It enables sLCA practitioners to identify “social hotspots” and “social opportunities” from a regional perspective. The location and characteristics of these social hotspots and opportunities can be analysed, in particular, for major production activities in a bioeconomy region in Germany. Therefore, according to this framework, the development of social indices and indicators, the collection of data and the approach used for characterising social effects need to relate to the geographical context of the product being assessed. The proposed framework can, thus, help to identify, monitor and evaluate the social sustainability of wood-based bioeconomy chains in a regional context.

Conclusions

This framework requires a high level of detail in the social inventory and impact assessment phase, in order to assess the regional foreground activities in a German wood-based bioeconomy region. It enables sLCA studies to identify which social hotspots and social opportunities occur and where they are located in the wood-based production system of a regional bioeconomy.

     

Potential trade‐offs of employing perennial biomass crops for the bioeconomy in the EU by 2050: Impacts on agricultural markets in the EU and the world

Perennial biomass crops (PBC) are considered a crucial feedstock for sustainable biomass supply to the bioeconomy that compete less with food production compared to traditional crops. However, large‐scale development of PBC as a means to reach greenhouse gas (GHG) mitigation targets would require not only the production on land previously not used for agriculture, but also the use of land that is currently used for agricultural production. This study aims to evaluate agricultural market impacts with biomass demand for food, feed, and PBC in four bioeconomy scenarios (“Business as usual,” “Improved relevance of bioeconomy,” “Extensive transformation to a bioeconomy,” “Extensive transformation to a bioeconomy with diet change”) to achieve a 75% GHG reduction target in the emission trading sector of the EU until 2050. We simulated bioeconomy scenarios in the energy system model TIMES‐PanEU and the agricultural sector model ESIM and conducted a sensitivity analysis considering crop yields, PBC yields, and land use options of PBC. Our results show that all bioeconomy scenarios except the one with diet change lead to increasing food prices (the average food price index increases by about 11% in the EU and 2.5%–3.0% in world markets). A combination of the transformation to a bioeconomy combined with diet change toward less animal protein in the EU is the only scenario that results in only moderately increasing food prices within the EU (+3.0%) and even falling global food prices (–6.4%). In addition, crop yield improvement and cultivation of PBC on marginal land help to reduce increases in food prices, but higher land prices are inevitable because those measures have only small effects on sparing agricultural land for PBC. For a transition to a bioeconomy that acknowledges climate mitigation targets, counter‐measures for those substantial direct and indirect impacts on agricultural markets should be taken into account.     

Revealing the Environmental Advantages of Industrial Symbiosis in Wood‐Based Bioeconomy Networks: An Assessment From a Life Cycle Perspective

The German government has recently initiated funding schemes that incentivize strategies for wood‐based bioeconomy regions. Regional wood and chemical industries have been encouraged to act symbiotically, that is, share pilot plant facilities, couple processes where feasible, and cascade woody feedstock throughout their process networks. However, during the planning stages of these bioeconomy regions, options need to be assessed for sustainably integrating processes and energy integration between the various industries that produce bio‐based polymers and engineered wood products. The aim of this paper is to identify the environmental sustainability of industrial symbiosis for producing high‐value‐added, bio‐based products in the wood‐based bioeconomy region of Central Germany. An analysis was conducted of three possible future scenarios with varying degrees of symbiosis in the bioeconomy network. A life cycle assessment (LCA) approach was used to compare these three scenarios to a traditional fossil‐based production system. Eleven environmental impact categories were considered. The results show that, in most cases, the bioeconomy network outperformed the fossil‐based production system, mitigating environmental impacts by 25% to 130%.     

Accelerating the development of a sustainable bioenergy portfolio through stable isotopes

Bioenergy could help limit global warming to 2°C above pre-industrial levels while supplying almost a fourth of the world's renewable energy needs by 2050. However, the deployment of bioenergy raises concerns that adoption at meaningful scales may lead to unintended negative environmental consequences. Meanwhile, the full consolidation of a bioenergy industry is currently challenged by a sufficient, resilient, and resource-efficient biomass supply and an effective conversion process. Here, we provide a comprehensive analysis of how stable isotope approaches have accelerated the development of a robust bioeconomy by advancing knowledge about environmental sustainability, feedstock development, and biological conversion. We show that advances in stable isotope research have generated crucial information to (1) gain mechanistic insight into the potential of bioenergy crops to mitigate climate change as well as their impact on water and nutrient cycling; (2) develop high-yielding, resilient feedstocks that produce high-value bioproducts in planta; and (3) engineer microbes to enhance feedstock conversion to bioenergy products. Further, we highlight knowledge gaps that could benefit from future research facilitated by stable isotope approaches. We conclude that advances in mechanistic knowledge and innovations within the field of stable isotopes in cross-disciplinary research actions will greatly contribute to breaking down the barriers to establishing a robust bioeconomy.

Livelihood activities and land-use at a riparian frontier of the Brazilian Amazon: quantitative characterization and qualitative insights into the influence of knowledge,values, and beliefs

We examined if smallholders that immigrated to the Amazon over the last 40 years (highway-era families) and households with historical ties to the region (rubber-era families) adopt different livelihood activities and land-use/land-cover (LULC) patterns, in four communities along the Tapajós River in the Brazilian Amazon. Using quantitative data, we characterized three portfolios of livelihood activities, each associated to different LULC. Both rubber-era and highway-era families practice a wide range of activities from all portfolios; however, families that have been in the region for several generations tend to adopt traditional activities (e.g., fishing, non-timber forest product gathering and sales), while recently settled families tend to practice agrarian activities more intensively (e.g., cattle ranching, sale of non-native crops). We then draw on qualitative data to examine some of the underlying reasons for these differences. While recognizing that livelihoods are complex systems with many influential factors, we reflect on some of the overlooked drivers of livelihood and LULC choices such as knowledge, visions of development, and the immaterial value and symbolic meaning of resources. We also reflect on how they shape intended land management choices and relate to household settlement histories. The implications for regional resource-use planning and future research are mentioned.

How to turn industrial biotechnology into reality

The emerging bioeconomy is pulled by consumers asking for sustainable products and processes, governments enforcing climate protection and industries demanding feedstock flexibility and last but not least it is pushed by progress in basic and applied science. It will use renewable carbon sources not only from agri- and silviculture, but potentially also from industrial flue gases - for example, from power generation and steel production. Connecting such industries with the future bio-chemical industry results in a challenging new value chain which connects thus far separated industries. Realising this value chain needs disruptive technologies in providing sustainable carbon sources and transforming them into precursors for biochemical production up to consumer products.     

Recognising and Translating Knowledge: Navigating the Political,Epistemological, Legal and Ontological

What does it mean to call something ‘knowledge’ today? What does this recognition or translation require? And what does it entrain? This introduction makes a novel synthesis of contributions to the Special Issue and advances observations regarding the ‘mythic’ qualities of intellectual property law, the precipitation of ‘nature’, and the importance of attending to what is lost when things and practices are also called ‘knowledge’. The papers cohere around a timely set of observations and critiques: critiques of the way the knowledge economy makes demands and defines expectations about value; of how intellectual property law lies behind and shapes exclusions, inclusions, and inequalities; of the ‘mythic’ status of assumptions informing laws about ownership; and the implicit hierarchy contained within types of knowledge as understood through the categories of western epistemology. By taking up effect rather than veracity and certainty, contributors leave the definition of knowledge to ethnographic subjects. That is, they attend to where and how things come to be called knowledge, and for what reasons, noticing how equivalences across practices, made for the purpose of creating the possibility of exchange value (and thus of encouraging circulation) does its work at the expense of multiple aspects, values, and relations that are also discernable in social processes that produce ‘knowledge’.

Empowered imagination and mental vulnerability: local theory of mind and spiritual experience in Vanuatu

‘Theory of mind’ in developmental psychology focuses on how children develop the ability to infer others’ beliefs, desires, and intentions. Anthropologists have taken up the notion of ‘theory of mind’ to explore the way cultural differences in representations of beliefs, desires, and intentions affect everyday lives. In Oceania, anthropologists have noted that inferences about others’ intentions are not accorded a privileged role in social interaction. In Vanuatu, I find, it is often the material, rather than immaterial, aspects of relatedness that are elaborated upon. People think about knowledge, creativity, meaning, and intention not as confined to a bounded mental or inner domain, but as discoverable through the body, and in the world at large. I argue here that this propensity to locate meaning and moral purpose as external to the mind corresponds to a ‘porous’ view of self and mind, and that this in turn may open people to experience vivid, intense, and often tangible forms of spiritual encounter.

Speed, Sex, Gay Men, and HIV: Ecological and Community Perspectives

Fifteen years into the HIV/AIDS epidemic, a great deal is now known about the different populations impacted by the disease, including those affected directly or indirectly by drug use. Anthropology has played a critical role in assisting with this task by identifying hidden populations, developing new methodological approaches, and targeting outreach efforts. In spite of this considerable body of ethnographic knowledge, men who have sex with other men (i.e., MSM, or gay and bisexual men) who use drugs have not received the same research attention as other drug users, despite the fact that they represent nearly one-fifth of AIDS cases in the U.S. with injection drug histories. In response to the alarming increase in HIV seroprevalence among this population, this ethnographic project provides preliminary data about those who are at dual risk for HIV through both homosexual behavior and injection drug use.
