Organic agriculture and food research (OAFR) is well established and there is an ongoing and vibrant discussion about the future research needs of organic farming. However, reviews of the research features of OAFR have been less common. During the editorial work on a collection of book sections about the state of the art of OAFR, we felt that the differences between the ideals of OAFR and the actual research practices invited critical debate. In this article, we label these differences—somewhat provocatively—as myths about OAFR. We identified seven myths: (1) OAFR follows a systemic research approach, (2) OAFR is guided by the International Federation of Organic Agriculture Movements Principles and organic regulations, (3) research priorities are defined in collaboration with practitioners, (4) transdisciplinarity is a key strategy in OAFR, (5) OAFR produces results that are directly applicable in practice, (6) the methods applied in OAFR differ fundamentally from those in research on conventional farming, and (7) organic researchers are fully integrated in the scientific community. We assume that our reflections will also inspire a broader discourse in the light of Organic 3.0, where a critical review of research practices should be central for the future development of OAFR.
Today, organic agriculture and food research (OAFR) is well established in many agricultural research institutions. Within the context of the future of organic farming (OF), International Federation of Organic Agriculture Movements (IFOAM) prepared a strategic paper, Organic 3.0, that includes an extensive debate about the necessary requirements and important research needs in OF (Arbenz et al. 2015; Niggli et al. 2008, 2016).
Besides that, over the last decade, numerous papers have addressed the following: how OF should be developed in the future; research strategies for OF; the demand, needs, and challenges of OF; analyses of the state of the art in OAFR based on stakeholder and expert interviews, focus group discussions, platforms, or literature reviews (Barabanova et al. 2015; Häring et al. 2012, Niggli et al. 2008; Padel et al. 2010; Rahmann et al. 2009), and evaluations of OAFR programs and procedures (Ekert et al. 2012; Lange et al. 2006; Wolf et al. 2011). These activities, focusing largely on the development of OAFR in Europe, have been organized partly through different institutions (see, e.g., DAFA Forum in Germany (DAFA 2015; Hamm et al. 2016)).
When it comes to research features in OAFR, we recognize that the discourse about them is limited and fragmented. The last and maybe sole comprehensive discussion on OAFR methodological features and ideals dates back from a review in the 1990s (see Lindenthal et al. 1996).
Also work of several mainly Danish researchers represents a significant exception, but focuses first of all on an ethical and systemic research perspective, however serve as an excellent example how the discourse on methodologies can be initiated (Alrøe 2000; Alrøe and Kristensen 2002; Noe and Alrøe 2003; Noe et al. 2008; Thorsøe et al. 2014; Watson et al. 2006). Their research is not only specifically directed on OAFR, but is inspired from experiences with OAFR (Alrøe et al. 2016; Alrøe and Noe 2011, 2014; Noe and Alrøe 2012; Noe et al. 2015). The TIPI report1 offers also some insights into research method and approaches, systems perspectives, and participatory aspects of research (Niggli et al. 2016). But when we look at the diverse papers on the future of organic farming, research features are not an issue (e.g., Rahmann et al. 2016). Further observations have been done within the context of the application of systems theory and inter- and transdisciplinarity in organic farming research, where we identified discrepancies between what the science community claims and what is reality in scientific practice (Freyer 2016a, b). Consequently, we argue that OAFR lacks critical discourse on research features (see also Jörgensen 2016).
Based on those observations, we believe that it is important to launch a new discussion about the research characteristics of OAFR. We structure our reflections using the term myth
A myth represents an idealistic image of OAFR that conflicts with the research practices and overall conditions of the science daily routines. Similar to Roland Barthes (1972), we see myths as connotations that present phenomena as natural conditions, when in fact they are socially constructed. The term “myth” has polemic sharpness and we use it in this article pragmatically as a conceptual “lightening rod” that draws our attention to the need to question many of our assumptions in regard of OAFR. In the following, we discuss seven myths about OAFR that are of relevance for the methodological discussions and for the continuing development of organic farming. For each myth, we present how prevalent it is in OAFR, why it is a myth, and further discuss different related consequences and suggest measures for improvement.
Why this is necessary? OF is still far from a mainstream food and farming practice. To unpack the potential of organic farming, it is necessary to develop research methodologies and practices that can help to better understand and develop OF’s specific qualities, including its potentials and limitations. Therefore, it should be of interest for scientists to critically analyze current state of the art of OAFR features in order to optimize their scientific quality. At least the diffuse nature of OAFR reviews and critical assessments beg for a book-length discussion to provide an overview of the current state of the art and the future of OAFR, which of course we cannot provide here. The idea of this article is therefore to initiate a critical discussion on the OAFR challenges and needs within the context of organic agrofood systems.
Material and methods
The foundation for the identification and discussion of the seven myths arises from insights gained while preparing an edited volume on OAFR (see Freyer 2016a). In this book (Freyer 2016b), 52 authors contributed 33 chapters and discussed the state of the art, and the future challenges of different fields within OAFR. After reviewing each of the chapters, we identified a list of myths. The list is not complete, nor without flaws, and we invite readers to reflect on our suggestions and to help extend and refine it. In addition, we reviewed additional literature that is related to the myths. We conclude with a brief discussion on how to address these controversies and some ideas for developing the methodological approach and practices of OAFR.
Results and discussion
Myth 1: OAFR follows a systemic research approach
It is often noted that organic agriculture follows a systemic rather than a more reductionist research approach often found in conventional agriculture. Organic farmers exclude certain external inputs, focus on the farm internal relations (e.g., between crop rotation and pest management or herd size and on-farm forage production), and try to close nutrient and energy cycles, and the farm is understood as an organism (Raupp 2000).
Also ideally, organic farming aims for a systemic marketing approach with short supply chains and direct consumer–producer relations (Freyer and Bingen 2015; Vogt 2007). Here organic products, their processing, trade, and consume is embedded in the regional economy. Therefore, it is often stated that organic farming is a system-oriented form of agriculture (see e.g., Høgh-Jensen 1998). This assumption is underlined by the IFOAM Principles, which also refer to systemic concepts like wholeness, cycles, and systems.
From this orientation researchers deducted certain requirements for OAFR. For example, Lindenthal et al. (1996) stated that there are five requirements that shall ensure a system-orientated research approach within OAFR: (1) a holistic approach, (2) long-term research, (3) consideration of local characteristics, (4) praxis orientation, and (5) regionality. The implementation of these requirements—which of course can also be discussed critically, but can serve as a guide for the discourse—asks for an inter- and transdisciplinary research design. For that, systems theory has been identified as a necessary theoretical foundation (Fiala and Freyer 2016; Freyer et al. 2010; Gibbon 2002; Ison 2008). The notion that OAFR follows a systemic approach seems to be widespread in the organic research community. Furthermore, “organic farming” is a prominent topic within the International Farming Systems Association (see Barbier et al. 2012), a community dedicated to foster the application of systems theory in the area of agricultural research, and also a central reference in the discourse on farming systems research in general (Darnhofer et al. 2012).
However, no comprehensive research about the application of systems theory in OAFR exists so far and our observation is that researchers commonly discuss the need for a systems perspective on OF, but rarely apply systems theory. The whole area of organic farming systems research has been also criticized to use the word “systemic” often quite freely without applying concrete systems approach (Bawden 1995, 2012; Fiala and Freyer 2016). Also when we look at the five requirements for systems-orientated research (Lindenthal et al. 1996), it becomes clear that not many research projects or publications can fulfill these criteria (Fiala and Freyer 2016) and mostly remain disciplinary orientated (see myth 5 and Freyer 2016a). Häring et al. (2012) state for true systemic research project, runtimes of 25 years would be necessary. There are some examples of long-term field trials (e.g., see overview Mayer and Mäder 2016), but researchers do not spend much time to dig into the details of systems theory and to unfold their potential for a deeper understanding of the organic system.2
Missing systems theory in higher education but also time constrains that are given through tight research schedules risk that the organic research community becomes more and more unaware of the need to conduct truly systemic i.e. systems research. The discrepancy between myth and reality is problematic for OFAR and its research community, because it creates blind spots that can be problematic for practitioners. There is need to initiate a broader scientific discourse about this discrepancy; otherwise, we will face problems like it is mentioned in the strategy for organic farming research by the Technology Innovation Platform of IFOAM, where it is stated that system-orientated organic farming research would be necessary, but is very hard to achieve (Niggli et al. 2016).
Myth 2: OAFR is guided by the IFOAM Principles and organic regulations
The understanding of the organic regulations is that they have to be in line with the IFOAM Principles and consequently the organic farming practices are guided by this ethical framework (see Padel et al. 2009; Freyer and Bingen 2015), but it is not so simple as such. Since more than one decade, we observe what is called bifurcation of the organic movement (Constance et al. 2008), representing a broad range of actors with rather different worldviews. As organic regulations continue to be modified, largely by economic (often corporate) interests, they increasingly appear to have almost forgotten the principles (e.g., through the increased application of all kinds of industrial fertilizers). As a result, organic practices risk losing their singular position as ethically framed (see also the conventionalization debate) (De Wit and Verhoog 2007; Goldberger 2011). The other position is that there are many efforts of farmers, traders, and consumers to seriously reflect their production, trade, and consumer habits following closely the ethical principles.
If and how organic researchers frame their research practices with the IFOAM Principles or not is more or less unknown. In part, the ethical framework of the IFOAM Principles is primarily intended for practice, but not for researchers and how they practice science or how their research aligns with the ethics (Freyer and Bingen 2015). From that perspective, it appears that science and practice live in different worlds and that values are differently of relevance in their daily practice (Freyer and Bingen 2015). Or is this a misinterpretation?
To understand the relation between OAFR and the ethics, a broader view on all kinds of interfaces might be helpful. OAFR reflects the Principles in different ways. There is some research on the development of the Principles (for an overview, see Freyer and Bingen 2015). Principles are part of a broader analysis how they are applied and translated into practices mainly in farming systems (Darnhofer et al. 2010; Padel et al. 2007), but often also within the context of (fair) trade, animal welfare (Vaarst and Alrøe 2012), or their philosophical foundations (Freyer and Bingen 2015). Only in some cases, research is framed by the organic principles (Alrøe and Kristensen 2002). In general, this research field is mainly fed through social scientists, while the majority of natural scientists is less engaged in this topic. If bifurcation also takes place in OAFR is an unknown issue. In this context, it is relevant to inquire about the ethical self-understanding of organic scientists and their awareness of IFOAM Principles in and the consequences for their research (Freyer et al. 2016). While research should not underlie any “moral control,” it might be of interest to study how scientists think about ethics and the extent to which the principles influence, i.e., guides the selection of research topic and their research practices.
We can argue that both regulations and IFOAM Principles are based on long-term experiences and are part of a continuous discourse of adaptations. In this sense, they do not limit the option space for research, but guide on already verified findings (Luttikholt 2007; Vogl and Axmann 2016). From this perspective, both principles and regulations do not restrict research, but offer a well-considered framework.3 On the other hand, this normative framework might hinder reassessment of the fundamentals of OA and also exclude consideration of possible solutions that could advance organic agriculture and food systems. Further reflections are necessary to clarify the relationship of IFOAM Principles and OAFR, i.e., organic researchers. Similar to many research calls asking today how far the research is in line with or contribute to the sustainable development goals (SDGs), we can argue that for organic research there could be a section asking how far research makes a contribution toward IFOAM Principles.
Myth 3: research priorities are defined in collaboration with practitioners
Historically, farmers and other members of the organic community played an important role to develop and drive OAFR (Vogt 2007). Therefore, there is the widespread opinion that understanding organic farming as system requires the integration of an inter- and transdisciplinary process for the identification of long-term research programs. Research should be done with and for the farmers. Consequently, it seems logical that also the research priorities are defined in collaboration with practitioners and indeed there are some examples for that, e.g., the German Federal Ministry of Nutrition and Agriculture identified priorities by interviewing actors all along the organic agrofood chain (Ekert et al. 2012). IFOAM, initiating the TIPI (Niggli et al. 2016), is working hard on bringing farmers and researchers together to identify research needs. Switzerland established a national forum of farmers and researchers to coordinate research priorities (Nationales Bioforschungsforum: http://www.bioaktuell.ch/aktuell/nbff.html), which is a very promising approach.
How to organize participatory processes is widely discussed in the literature on transdisciplinary research (Enengel et al. 2012, Lang et al. 2012, Leavy 2016, Mobjörk 2010, Scholz and Steiner 2015). However, there are several obstacles in the process of collaboratively defining research strategies. A central challenge in identifying research needs involves finding ways to balance the selection of participating stakeholders with their willingness to be part of such a process. The research topics identified by stakeholder groups might be highly skewed toward the specific interests of those choosing to participate in the process (Baars 2011). Thus, the results may favor those who are most attentive to or interested in the research, while those not participating or interested in the research are excluded. It also makes a difference if stakeholders name research problems purely from their individual perspective, or as a result of a group process or from a broader societal perspective (Fichten 2014). The perspective of stakeholders can fruitfully inform many research topics. But not all research topics are appropriate for or require a stakeholder process. Such research topics might include the development of a method to identify enzymes for a digestion process, or the analysis of the biochemical mechanism of an interaction between a predator and an insect. Also a demand-driven research agenda confronts many tensions, e.g., different and often limited perspectives on innovations of the actors involved; sometimes conflicting processes, monitoring, and output evaluation criteria; and information and knowledge asymmetries between the actor groups (Noe et al. 2015), even there are serious efforts and experiences to reduce these differences (Ingram et al. 2018; Röhrig 2006). These factors might influence researchers’ capacity to successfully act in the research planning. Because the majority of those involved often lack the capacity to initiate such a process, “participation” does not per se increase research quality (Klerkx and Leeuwis 2009). But it is the researcher’s responsibility to adapt, i.e., transform stakeholder ideas into the research setting, if they claim to practice farmer-oriented research. And without question, a comprehensive literature review should be always part of the research process, even when the focus is stakeholder-driven research.
Myth 4: transdisciplinarity is a key strategy in organic farming research practice
Transdisciplinary research often linked with action research (Hadorn et al. 2006; Reason and Bradbury 2001)—defined as not only crossing disciplinary boundaries (interdisciplinarity) but also including non-academic stakeholders in the research process (Jahn 2008)—has become quite popular in Farming Systems Research and also in OAFR. In OAFR, calls for research proposals increasingly require scientists to identify how the proposed research will meet the needs of farmers (Freyer 2004, 2016a). Although the collaboration between practitioners and researchers is not an issue that is specific to OAFR, organic farming has a strong history in farmer-driven research (Fiala and Freyer 2016). It seems natural that the lack of institutional support during the pioneer phase of the organic farming movement (Barton 2018; Vogt 2007; Willer and Schmid 2016) led to a high importance of on-farm research in close collaboration with farmers to advance organic farming practices in comparison to mainstream farming (Vogl et al. 2015). Therefore, it is not surprising that in early discussions about the methodological requirements for organic farming, the high importance of and relevance for practitioners was emphasized (Lindenthal et al. 1996).
Today, researchers still face many hindrances, if they want design transdisciplinary research projects. First, conducting transdisciplinary research requires certain competencies (see Muhar et al. 2013; Nash et al. 2003). Without those competencies, researchers will struggle to manage the complex and sometimes exhausting process of integrating stakeholders in their project. Unfortunately, teaching transdisciplinary competencies is still rare in higher education (Dedeurwaerdere 2013; Merck and Beermann 2015; Sherren 2008) and by far not a common part of many OARF-related curricula. The establishment of respective lectures often faces institutional problems, because of the special features of didactic methods (e.g., case study research (see Freyer and Muhar 2006; Larson et al. 2011)) necessary to train transdisciplinary competencies.
Second, although more and more calls demand a transdisciplinary research approach, there are institutional barriers to design projects that way. Often, it is not possible to include stakeholders already in the proposal writing process and there are too little resources to manage the transdisciplinary processes; workload necessary to conduct successful transdisciplinary research is underestimated (for example, see the difficulties faced in the “FarmPath” project (Pinto-Correia et al. 2015), or the agricultural European Innovation Partnership (EIP_AGRI),4 where farmers are obliged to take over the administration and paperwork, which is going beyond their capacities).5 In addition, there are currently still few incentives to conduct transdisciplinary research since most of the scientific journals still focus on disciplinary approaches (Roux et al. 2017).6 On the other hand, there are also excellent examples, e.g., the German “Demonstrationsbetriebe,” showing how to communicate organic farming practices with the public,7 or the “Leitbetriebsnetzwerk” guided by the University of Bonn, which demonstrates how to establish a researcher–farmer collaboration on farm research approach (Berg et al. 2003).
To summarize including stakeholders into the research process is a crucial part for OAFR, but it must not become a hollow buzzword. We have to be clearly aware of the limitations, the difficulties, and the costs connected with moving out of the ivory tower. This awareness should lead to more adaptable research institutions in regard of funding and proposal design and in higher education systems that prepare organic researchers for this demanding task. It is further recommended to link with the diverse research communities engaged in transdisciplinary research since decades.
Myth 5: OAFR produces results that are directly applicable in practice
As already mentioned in myths 3 and 4, the (immediate) usefulness of results for practitioners is often identified as a key feature of OAFR, already raised in the early days of organic farming (e.g., Lindenthal et al. 1996). Indeed, basic research within the field of OAFR is rare, and OAFR has a long tradition of focusing on applied research approaches. This dominance of applied research may also be due to the demand for solutions that can be directly transferred into practice (Ekert et al. 2012). Farmer’s interest is the usefulness of a research result under real farming conditions, while for researchers, interests are beyond this target, including also simply to test, evaluate, or monitor something,
Thus, it is a misconception that results from applied science automatically guarantee their (short term) applicability in practice. The transferability of research results is confronted with four challenges: (1) Organization—the direct application of research results often requires additional resources that are not considered to be part of classical research projects. (2) Qualification—scientists are only partly qualified for this task, because transforming and transferring results into practice is its own profession (Fichten 2014). (3) Appropriateness—not all research results qualify for direct application. The research intents other objectives or refers to other methodological approaches relevant for the research process that offers no space for a transfer oriented strategy. (4) Time—research projects that are limited to 3 years often cannot produce scientifically robust and qualified results to recommend farmers.8
Transdisciplinary action research (Stokols 2006) includes the practice orientation but often risk failing due to the mentioned challenges under myth 4 (see also Dressel et al. 2014; Freyer 2004; Freyer and Muhar 2006; Hoffmann et al. 2009; Rieckmann 2015; Ison 2008). In addition, those action-orientated approaches come with another trade-off: If the focus is more on a specific farming system, a kind of case study approach, the produced results may show great ways to improve the situation within this farming system, but may not be applicable in any other farm. This can be explained not only through site-specific agro-ecological conditions but also because of the farmers influenced in these trials, i.e., the management capacities or the technical equipment of a farm. In such case study-oriented research, which has its own value (Flyvbjerg 2006), the aim is not the direct applicability of a result in other farms, but to find the best solutions from a systems perspective for one farm.
To summarize OAFR aims at producing research results that are directly applicable in practice. To be realistic, from a research point of view, this target is not always to fulfill, due to the intended research focus, i.e., the research objectives and other factors. Furthermore, it requires specific competencies, institutional support, and additional resources. In general, we still face obstacles how to measure the scientific and non-scientific impacts of transdisciplinary research (Wolf et al. 2013), which provides the procedures and (mixed) methods (Popa et al. 2015) to guarantee high applicability of research results in practice (Green 2008).
Myth 6: the methods applied in OAFR differ fundamentally from those in research on conventional farming
Since it is often stated that OAFR has specific requirements and that it follows a systemic approach, as well as ethical principles, it is sometimes assumed that OAFR methods also differ from methods applied in conventional farming research. But no meta-studies are available to confirm this assumption. During the editorial work of the book Ökologischer Landbau-Grundlagen, Wissensstand und Herausforderungen (Freyer 2016b), we concluded that with the exception of plant and animal breeding, ethics, and research on bio-dynamic agriculture (Geier et al. 2016; Herold 2016; Horneburg 2016), currently alternative methodological approaches that are specifically developed and applied in OAFR are limited.9 We only can observe that some methods are more relevant in OAFR research, e.g., microbiological soil analysis (Mäder et al. 2002), than others, or specific methods are excluded, which is the case, e.g., in animal and plant breeding.
When it comes to the results of any applied method, we observe differences between both farming approaches. Same results must not lead to the same interpretations and consequences in practice. For example, both conventional and organic researchers concerned the availability of phosphorous in the soils, but they propose quite different management solutions. In organic farming, the crop rotation and organic manure and compost management as well as the pH are to optimize, and the nutrient status (farm gate and plot specific) is to analyze before adding any fertilizer from outside the farm. In conventional farming, the first recommendation almost always is to apply mineral fertilizer. In each system, also the recommended type and amounts of fertilizers are different.
More research sector specific detailed analyses and the identification of differences and communalities in the application of methods between organic and conventional research, and more in-depth reflections about the need of new or alternative methods to understand and further develop the organic system in future, would be useful. Also, it seems natural that both researcher groups can learn from each other, how they apply methods and interpret results (Rahmann et al. 2016).
Myth 7: organic researchers are fully integrated into the wider scientific community
Given the broad range of OAFR, it appears that organic farming has become a topic of interest within the wider scientific community. Publications and scientific conferences on organic farming have been increasing in the last two decades (see www.orgprints.org/). There are numerous options to present OAFR in scientific peer-reviewed journals, as well as conferences, including those journals that traditionally were established for research on conventional agricultural. From that perspective, we can conclude that organic research and the related research community are well embedded in the overall scientific community.
When we look at the “organic” researchers, we identify different types with different access to the organic and the conventional research society: (a) researchers who focus only on OAFR, (b) those who deal with both conventional and organic systems, (c) those who do OAFR by default, and (d) those who exclude OAFR, but write critically about it. These researchers are differently integrated and linked in the organic researcher networks (e.g., ISOFAR, TIPI, etc.) as well as in the diverse conventional ones. Hülsbergen and Rahmann (2014) argue that the circle of organic researchers has grown very slowly in recent years, as documented as well by Ekert et al. (2012). DAFA (2015) similarly notes that the contribution of basic science researchers in OAFR is very limited. These observations indicate that there is an untapped research potential between the different research groups—organic and non-organic—that could benefit from greater communication. This potential addresses not only new topics, i.e., technologies and methods in the natural sciences, or, e.g., developments in transdisciplinary sciences (Brandt et al. 2013), but also contributions from scientific disciplines that have been less engaged in OAFR, e.g., medicine, or methodologies that have not paid attention to organic farming practices and product qualities. It is also clear that the organic research community is a relatively small one and has a limited number of research facilities and institutes with often low financial capacities, including laboratories, or budgets to employ a broad range of methods. In short, it may be of interest for organic researchers to intensify the collaboration with non-organic researchers/institutes, and who, in turn, may become inspired to engage into OAFR and related research topics.
There has been little debate over organic farming, organic agriculture, and food research since Lindenthal et al. (1996). This article summarizes and critically discusses the current situation along seven myths about OAFR. We expect that what we reflect as a myth may generate some controversy and disagreements; however, it was intended with this article to initiate a critical discourse. Some of our initial conclusions include:
- There is need to specify in the diverse organic research sectors the systems approach, activating the tool box of all kinds of systems theories and methods.
- IFOAM Principles guide the organic practices and therefore should be more part of research on organic farming and their future development.
- Best practices on identification of research priorities in collaboration with stakeholders should be further strengthened; however, it is to keep in mind that there are cases where researchers have to follow other research priorities.
- Organic researchers should access the transdisciplinary scientific movement and their theoretical and methodological discourses to better use the potential of transdisciplinary tools and related mixed methods.
- There is need for a more detailed discourse on the applicability and transferability of research results. Not each research is qualified due to its problem structure, and related methods for developing solutions. This is also to communicate to the stakeholders.
- A research platform on organic farming methodologies and (systems) theories, e.g., supported via a European COST action or the establishment of a platform like FQS (www.qualitative-research.net/), might offer a format to deepen the debate on (innovative) OAFS-specific methods and their potential to innovate the organic farming system.
- Recommendations are of low significance if not supported by the research policies and budgets in the respected countries as well as activities specifically in higher education to train students in the field of organic agriculture and food sciences.
Especially in the context of the further development of organic farming as “Organic 3.0/4.0,” we argue the importance for the scientific community to engage with these myths, to reflect upon them, and to discover others. We have done so, and we invite others to do so as well. We believe that such reflection could launch an important creative process for increasing the research quality for the organic agriculture and food system.

2.An example where systems theory is highly relevant is, e.g., research from Noe and Alrøe (2012), referring to Niklas Luhman’s social systems theory (Luhmann 1995). They explain the operational closure and systems logic of a farming system and how this closure is produced and reproduced. These insights are also significant for understanding the circumstances under which the conversion of a farm occurs and why the conversion is one of the most challenging steps for an organic actor (Freyer and Bingen 2012, 2014), and in combination with practice theory (Nicolini 2012), the systems’ perspective helps us understand this process by highlighting the linkage between practices and social systems. Another example is introduced by Nuutila and Kurppa (2016). They combined a systems perspective with the activity theory to interpret the Finnish organic food chain.
3.With the latest established SDGs (sustainable development goals), OAFR confronts a new and comprehensive ethical framework for sustainable development. SDGs already guide some research programs (e.g., Lund 2015). Consistent with this development, the organic movement should show the extent to which the IFOAM Principles and related programs and activities of the organic movement embody the ethical dimensions of the SDGs (see also Freyer et al. 2016: Niggli et al. 2016; Rahmann et al. 2016). In fact, OAFR itself should begin to critically discuss how the Principles might be adjusted or reinterpreted in light of the SDGs.
5.Statement by BioAustria representatives
9.An example for methods that are specifically in organic farming research is the spade diagnosis (Munkholm 2000), which originally was not developed by organic actors (Görbing 1947), or bio-dynamic research, which includes so called “holistic” methods, e.g., chromatographic methods for assessing the quality of products (Turinek et al. 2009; Weibel et al. 1998).
