Publication Biokraftstoff-Zertifizierungssysteme ISCC und REDcert : Darstellung, Vergleich und kritische Diskussion(2011) Bücheler, GerolfSeit Jahren wird die Biokraftstoffproduktion weltweit mit ihren beiden Haupttreibstoffen, Bioethanol und Biodiesel, immer bedeutender. In 31 Ländern existieren auf nationaler Ebene Beimischungsverpflichtungen für Biokraftstoffe. Die Situation auf dem Biokraftstoffmarkt wird weltweit durch staatliche Förderung beeinflusst. Dies trifft auch auf die Biokraftstoffpolitik der EU zu. Im Jahre 2009 erfolgte die letzte große Änderung dieser Politik, die seit Januar 2011 unter anderem die Nachhaltigkeitszertifizierung von Biokraftstoffen vorschreibt. Die Berücksichtigung des Nachhaltigkeitsgedankens in Verbindung mit der Entwicklung der EU-Biokraftstoffförderung entstand als Folge der Kritik an den Biokraftstoffen: Biokraftstoffe vernichten Regenwald, seien zur Bekämpfung des Klimawandels ungeeignet und lassen die Bevölkerung in Entwicklungsländern hungern. Nach der Darstellung der relevanten rechtlichen Grundlagen und einem Überblick über die Nachhaltigkeitszertifizierung folgt ein Vergleich der beiden bislang in Deutschland zugelassenen Zertifizierungssysteme für Biokraftstoffe International SustainabilityandCarbonCertification (ISCC) und RenewableEnergyDirectiveCertification (REDcert). Beide Systeme werden auf Unterschiede und Gemeinsamkeiten untersucht. Dabei werden jeweils die rechtliche Grundlage, die Biokraftstoff-Nachhaltigkeitsverordnung (Biokraft-NachV), und die von der für Nachhaltigkeitszertifizierungssysteme zuständigen Behörde, der Bundesanstalt für Landwirtschaft und Ernährung (BLE), gemachten Ausführungen zur Biokraft-NachV einbezogen. Anhand der Kritikpunkte, dass Biokraftstoffe klimatisch unsinnig seien, wertvolle Ökosysteme vernichten würden und negative Auswirkungen besonders auf Menschen in Entwicklungsländern hätten, folgt eine kritische Diskussion der Nachhaltigkeitszertifizierungauf Basis der Erneuerbaren Energien Richtlinie (EER), die mögliche Schwächen und Chancen aufzeigt.Publication Economic analysis of organic certification systems : determinants of non-compliance and optimum control strategies(2012) Zorn, Alexander; Dabbert, StephanOrganic certification systems are prerequisite for the existence of a large-scale organic food market. Despite a well-established and generally effective control system, fraud regarding organic food that passed organic controls is detected regularly. This cumulative thesis consisting of four articles addresses current questions regarding the improvement of organic certification systems. The need for governmental supervision of an organic certification system run by private control bodies is demonstrated by a game theoretic model. A framework prepares the statistical analysis by conceptually linking factors that can influence organic control results. The case study on German supervision data from the years 2006 to 2008 reveals significant differences between private control bodies regarding the number of severe sanctions imposed, i.e. fundamental control results. These data that were collected for supervision of the control system, however, are not sufficient to explain these differences. This is due to shortcomings in the data collected. Key terms of the data are not defined and the variable definitions seem to change over time. This study concludes that there is more detailed and reliable data from organic control bodies needed to understand the determinants of non-compliance with an organic standard. Detailed data on organic farm controls from the years 2007 to 2009 were supplied by two control bodies. Theoretical considerations founded on the ?Economics of Crime? approach yield hypotheses on factors affecting non-compliance with an organic standard. The data provided by a German and a Swiss control body are analysed by two different logistic regression models. The probability of receiving a sanction (which is used as proxy for non-compliance) is estimated on farm level by using data on farm and farm production. Such an approach to assess the determinants of non-compliance has not been used previously in the literature. Given the gradual sanction system, an ordinal logistic regression model is appropriate for the analysis of the German data. Swiss data are analysed by a random effects logistic regression model. Both models confirm some of the factors contributing to the risk of non-compliance that are applied in qualitative risk assessment so far. Control results from previous years, the overall farm complexity and the farm livestock production complexity, as well as farm size are factors that increase the probability of receiving a sanction. Risks connected to specific crops or livestock types that could come along, e.g., with particular requirements of the production method cannot be confirmed across the models. The explanatory value of both models is likely to be improved by the integration of further variables, such as data on farmers? personal and financial characteristics. The heuristic model builds on the results of the econometric models. This model adopts a societal view on the control system by considering the costs of controls and the damages resulting from non-compliance with an organic standard. Monte-Carlo simulations illustrate the relationship between important parameters for optimising control strategies. These simulations show that even without fines a situation can occur where most operators comply. The different approaches to analyse control data encounter difficulties inherent to the control data. In this context, the dark figure consisting of undetected non-compliances, inhomogeneous detection probabilities linked to particular production methods, and a potential positive confirmation bias connected to the risk based control approach are especially relevant. The working hypothesis that these potential biases are distributed randomly deserves closer attention in subsequent studies. Such future analysis should be based on even more detailed data, e.g., pooling original data from different control bodies in a control system. Such a data base would allow focusing on severe non-compliances which occur only rarely. Furthermore, pooled data could be used to investigate issues that are fundamental for the supervision of a control system such as a control body effect on the detection of non-compliance. This thesis presents important results that can be consulted for further analysis of organic control systems. Beyond, the approach, the methods used, and the results obtained are of general relevance for food certification systems beyond the organic sector.Publication Effects of agricultural commercialization on land use and pest management of smallholder upland farms in Thailand(2016) Grovermann, Suthathip; Berger, ThomasOver recent years, economic development, policy changes, new technologies and population growth have been motivating farmers in Thailand to intensify and commercialize their production activities. As part of this agricultural commercialization and intensification process, Thai upland farmers have adapted their farming practices to increase crop production and productivity levels. This thesis clearly demonstrates that there is a positive relationship between land use intensification/commercialization and the use of chemical-based pest management activities, i.e. farmers have increasingly relied on the use of chemicals for the protection of their crops. As part of the agricultural intensification and commercialization process, concerns about the potentially negative impact of pesticide use is often downplayed, while the benefits of pesticide use in terms of improved crop returns ignore the indirect costs they also incur. This has also led to a situation in which local farmers do not always use pesticides in an appropriate way; they tend to overuse and misuse the chemicals, to avoid losses among their high-value crops. Due to farmers’ limited awareness of and lack of protection against the potential dangers inherent in chemical pesticide use, they still use pesticides which contain cheap compounds such as the herbicides Paraquat and Glyphosate. The application of these chemicals is restricted in a number of other countries, but these represent two of the three most commonly used pesticides in the study area. The survey described here sought to provide evidence that agricultural commercialization in Thailand over recent years has led to a reduction in the variety of pest management practices applied, and that many Thai farmers have become completely dependent on the use of agrochemicals, expecting that this approach will fully prevent any losses in crop yields. In this context, it can be observed that farmers have become locked into using chemical pest control methods, creating a situation in which attempting to control one risk through the increasingly heavy and exclusive use of pesticides, has led to a number of other, new risks developing. This research also reveals that market prices, pests and diseases have become the dominant risks affecting farm performance within the Thai commercial farm sector, while among Thai subsistence farmers the loss of family labor is of key concern. The farmers in the study area have a variety of attitudes towards risk, and differences in expected rates of return influence the types of risk protection tools used. The findings show that agricultural commercialization is associated with a rapid adoption of synthetic pesticides and an exponential growth in the quantity of pesticides applied per hectare. As the risk management strategies used by commercial farmers are mostly aimed at crop protection, they use large quantities of synthetic pesticides to manage crop pests and diseases. The present research also finds that the effectiveness of pesticide use increases significantly as levels of commercialization increase. Pesticide use is perceived as increasingly useful in this process, being considered an essential factor for raising agricultural output and farm income. However, there is a need to pay more attention to the potentially adverse effects of pesticide use on human health and the environment and to improve producers’ level of understanding of the risks involved in pesticide use, which will help them make better decisions regarding the risks and consequences involved. A number of studies have suggested that pesticide regulations in Thailand should be better enforced, that consumer demand for certified products should be encouraged, and that training on food safety should be offered to farmers. The Thai government has reacted to these calls by introducing policies and projects aimed at the adoption of sustainable agricultural practices; however, these policies have not been promoted effectively, and so have not fixed the core problem. The Q-GAP program is a good example of this. This thesis reveals that Thai upland farmers still do not understand the logic behind the program introduced, and so lack any motivation to follow sustainable farming practices. This situation is made worse by the lack of any effective program implementation and follow-up activities, such as farm auditing. The Q-GAP program has been implemented with a strong focus on farm auditing and residue testing, and little focus on the positive consequences of a reduction in pesticide use levels. The program also does not provide farmers with suitable alternatives to manage their pest problems. Certified farmers continue to almost entirely depend on synthetic pest control. In principle, under the program farmers are encouraged to practice integrated pest management (IPM) methods in order to achieve Q-GAP certification. But it was found that a considerable number of farmers were not familiar with the term IPM and have a limited understanding of the approach. IPM offers alternative pest management methods to farmers and also takes into account traditional pest control methods, not just the use of pesticides. Therefore it could have a positive role to play in helping to reduce pesticide use. However, in reality, the promotion of integrated pest management methods is not enough in isolation. As this thesis shows by means of an ex-ante assessment of pesticide use reduction strategies with the MPMAS simulation package, the use of a combination of measures, such as the promotion of IPM through financial adoption incentives combined with the introduction of a sizeable sales tax on pesticides, could lead to a very substantial reduction in pesticide use – by up to 34% on current levels, without adversely effecting general farm income levels. Thus, policymakers should promote alternative pesticide use reduction strategies by combining pesticide taxation with the introduction of integrated pest management methods, the application of a price premium on safe agricultural produce or the introduction of subsidies for bio-pesticides. Furthermore, there is a need to raise farmers awareness about pesticide risks and to increase investment in the diffusion of integrated pest management practices. Thai upland farmers might be willing to introduce more sustainable agricultural methods if they were to fully understand the consequences of pesticide use on their health and the environment, as well as know more about the biology, behaviors and physiology of the pests themselves. Building knowledge is critical in this regard. To achieve this, there needs to be more interaction between researchers, extension workers and farmers, plus more policy options introduced to support farmers in their transition to a more market-oriented production environment.Publication The potential of certification for climate change mitigation in the agri-food sector : a case study of carbon neutral certified coffee from Costa Rica(2017) Birkenberg, Athena; Birner, ReginaAdvancing economic, social and environmental sustainability in the agri-food sector is increasingly pursued by various actors along global value chains. One option to address sustainability concerns is to use voluntary sustainability standards and certifications/labels as market-based governance tools for self-regulation. Recently, the demand for particular climate standards and labels has increased, however little is known about their potential and challenges. Individual aspects of such voluntary sustainability certifications have been investigated, such as the effectiveness and impact of certifications or the purchasing decisions of consumers. However, a holistic and interdisciplinary approach by considering the complete value chain is rare and, thus challenges are overlooked and proposed solutions remain limited in scope. Moreover, LCA-based certifications addressing climate change mitigation present a new field of research. Against this background, this thesis aims to elicit the challenges and potential of sustainability certification in the agri-food sector. Taking the case of the world’s first carbon neutral certified coffee, the complete chain – from standard development to consumer choices – has been examined. This coffee is produced by Coopedota, a Costa Rican cooperative of small-scale farmers, and exported to a family-run specialty coffee roaster, Hochland Kaffee Hunzelmann GmbH, in Germany. In the case under consideration, a newly released and highly prescriptive standard for carbon neutrality, the Publicly Available Specification (PAS) 2060, has been adopted since 2011. PAS 2060 is the first independent international standard for carbon neutrality that provides a common definition and a recognized method that is based on a life cycle assessment (LCA). To achieve carbon neutrality, the respective greenhouse gas (GHG) emissions are compiled, before continuous reduction activities are executed and the residual GHG emissions are offset by purchasing carbon credits. Costa Rica is relevant because it is actively pursuing carbon neutrality at the national level and the case of Coopedota serves as a pioneer in this field. In this thesis, an interdisciplinary case study approach is used to investigate in a holistic manner the challenges of carbon neutral certification in the agri-food sector. The study is guided by a conceptual framework developed from relevant literature on voluntary sustainability standards. The three specific objectives of the thesis are: (1) identify the success factors that made the carbon neutral certification in Coopedota possible and understanding the major challenges related to the standards implementation; (2) estimate the potential of on-farm carbon sequestration to compensate for the coffee carbon footprint and reduce carbon offsetting; and (3) estimate the willingness to pay for a carbon neutral label among German consumers of specialty coffee. This thesis contains three main chapters in addition to a general introduction and discussion. The first chapter addresses existing knowledge gaps regarding the role of social network dynamics, actor characteristics and linkages for successful pioneering in sustainable development, and investigates the challenges of implementing PAS 2060 by Coopedota. Qualitative research methods, such as in-depth interviews, participatory social network and process mapping as well as field observations were applied. The study found the prior achievements of the cooperative (e.g. compliance to ISO norms) and a ‘fertile ground’ in terms of ongoing climate change mitigation policies, as important factors for the successful implementation of the standard. Further success factors were a strong central and visionary actor and a diverse network of supporting actors from science, business and politics. The main challenges in implementing the carbon neutral certification were the acquirement of reliable farm data and the advertisement and communication of a carbon neutral label. The second chapter focuses on the problem that biogenic carbon sequestration is rarely considered in LCA-based standards. To estimate the annual potential of biogenic carbon accounting in coffee-agroforestry systems (CAFS) a literature review was conducted and the carbon sequestration based on a carbon inventory at the coffee farms was modeled. The results of a 20-year simulation show that on average, CAFS at Coopedota can compensate the carbon footprint of coffee by approximately 160% annually. Simultaneously, a trade-off between carbon sequestration and productivity at reduced inputs appears, which should be minimized. In the third chapter a marginal willingness to pay (WTP) of € 1.70 for a carbon neutral label was identified on a 250g package of specialty coffee by a discrete choice experiment among German consumers. Yet this marginal WTP was lower than the marginal WTP among the same consumers for direct trade claims or a Fair Trade certificate. Direct trade claims refer to the situation where direct trade relations exist; however, they are not certified and only declared by the retailer, as in the case of the family-run coffee roaster Hochland Kaffee Hunzelmann GmbH. Moreover, a positive synergistic effect was discovered for the combination of the carbon neutral label with direct trade claims. However, a public awareness on the contribution of agriculture to climate change is missing, as is the familiarity of the public with carbon concepts. Concluding, LCA-based certification for carbon neutrality can be a promising market-based tool for the agri-food sector to mitigate climate change. Such certification holds promise because it addresses recent demands for climate relevant information on agri-food products, while benefitting producers, the environment and consumers alike. Examples of these benefits include a potential increase in resource use efficiency, identification and minimization of GHG emission hot spots and trustworthiness among consumers due to the prescriptive nature of the standards. Additionally, the interdisciplinary case study approach enabled the identification of multi-faceted challenges and recommendations. One recommendation is that an agricultural perspective needs to be integrated into the standard by, for example, enabling the accounting of biogenic carbon sequestration. Such carbon accounting would prevent criticism of carbon offsetting and foster synergies between climate change mitigation, sustainability, and resilience. Particularly in the case of higher carbon prices, carbon accounting would be economically interesting but further research is needed to provide a robust dataset to enable it. Independent from a potential premium price for the label, access to capital and governmental support programs, especially for smallholders in less developed countries, can foster the implementation of greener technologies and allow stakeholders to benefit from increased efficiencies. The findings of this thesis indicate that coupling a carbon standard with existing sustainability standards, which use similar datasets, could ease the acquirement of reliable farm data on GHG emissions and reduce costs. Moreover, a coupling of standards could ensure additional sustainability practices, beyond the climate aspect, as already associated by consumers. This study also indicates that to establish markets for carbon neutral products, consumers first have to be aware of the extent of the agri-food sector’s contribution to climate change and consumer responsibility in tackling this problem through their purchasing behavior. This thesis further illustrates the importance of innovators in advancing development goals. Taking action on climate change mitigation and shaping a more sustainable agri-food sector requires strong initiatives and visionaries on the ground, as exemplified by the pioneering case of Coopedota.
