Estimating the demand for risk reduction from foodborne pathogens through food irradiation
Authors: Hartl Jochen , Fox John (Sean)
Published: August 2024

In this study the response of US consumers to irradiation in meat processing is examined. Despite scientific evidence of the effectiveness and safety of irradiation, meat processors and retailers have been slow to market irradiated beef products due to uncertainty about consumer acceptance. The objective of this study was therefore to examine the factors influencing consumer demand for irradiation using data from a contingent valuation (CV) survey with 819 households in eight midwestern US states. The analysis focused on the value of reduced risk from Escherichia coli O157:H7 and Salmonella in ground beef consumption. Respondents were on average willing to pay a price premium of 22 cents/lb. for safer ground beef. Willingness to Pay (WTP) amounts were influenced by protective actions at home and varied partly with the scope of the risk reduction.

Wetterderivate: Ein Instrument im Risikomanagement für die Landwirtschaft?
Authors: Berg Ernst , Schmitz Bernhard , Starp Michael , Trenkel Hermann
Published: August 2024

The risks associated with farming activities are likely to increase in the future. It, therefore, appears worthwhile to analyse new risk management instruments. This paper investigates weather derivatives for which a market has already emerged in the USA. Contrary to traditional financial derivatives, their payoff is determined by future weather events, such as temperature or precipitation. Thus, they hedge risks which result from climate. Since they address production risks they are complementary to instruments that hedge price risks, such as future markets. The objective of the paper is to evaluate the economic impacts of weather derivatives and to assess their potential as farm level instruments of risk management. After outlining the main characteristics and the functioning of weather derivatives and their emergence, emphasis is placed on model calculations to quantify farm level impacts. The potato farm is used as a case study. Empirical data on yields and weather variables are taken from an experiment station of the Chamber of Agriculture at Hanover, Germany. After studying the relationship between yields and weather variables, the findings are used to design an option based on a precipitation index. Stochastic simulation is then used to assess the effects on the probability distribution of revenues. The results show that weather derivatives can be useful instruments of risk management in agriculture. Since there is still a lack of knowledge with respect to some of their economic impacts, further research is needed. This refers to the choice of suitable commodities and weather indexes, the contractual design and methodological aspects of pricing and of integrating weather derivatives into the risk management of farms. Last but not least, the question has to be answered, as to which partners would be willing to accept the risk that farmers intend to reduce by means of weather derivatives.

Entwicklung und Zukunft der EU - Agrarhandelspräferenzen für die südlichen und östlichen Mittelmeeranrainerstaaten
Authors: Grethe Harald , Nolte Stephan , Tangermann Stefan
Published: August 2024

The EU has recently completed negotiating a series of association agreements with mediterranean countries. Trade preferences for agricultural goods which are granted under these agreements as well as under former arrangements are analyzed by calculating the value of preference margins at several stages in the evolution of preferences. The total value of preference margins for all countries covered was about EURO 130 million under the agreements in the mid-seventies and increased by 48 per cent until 1995. It was eroded by about 14 per cent until 2000 due to the reduction of EU MFN tariffs. The extended preferences under the new agreements more than compensate for this erosion of preferences and result in a total value of preference margins of EURO 226 million once all agreements have entered into force.
Optimale Vertragsdifferenzierung in der Agrarumweltpolitik
Authors: Glebe Thilo
Published: August 2024

This article deals with the optimal differentiation of agri-environmental contracts based on a self-selection mechanism. The paper demonstrates that both economic efficiency and effectiveness of public expenditures can be increased, if a menu of combinations of farming practices and payments are offered. However, there is a trade-off between efficiency and effectiveness, since the optimal programme minimising government expenses does not simultaneously minimise farmers’ opportunity costs. A numerical example of differentiated agri-environmental contracts, aiming for the reduction of nitrogen fertiliser in wheat production, illustrates that efficiency and effectiveness gains can be substantial. Furthermore, it is shown that economic rents for agricultural producers do not necessarily shrink as a result of contract differentiation, if the latter aims for the minimisation of public expenditures.
Das neue Gentechnikgesetz – ein Gentechnikverhinderungsgesetz? Eine umweltökonomische Analyse der haftungsrechtlichen Neuerungen im Gentechnikgesetz
Authors: Becker Alexander , Holm-Müller Karin
Published: August 2024

In this article, legal consequences of the new German genetic engineering act are analyzed. In addition environmental economic analysis is presented of those parts of the act that introduce new litigation regulation to farmers. The different kinds of external costs arising from genetic engineering of plants and their allocation to different actors are considered. The paper focuses on the costs resulting from the postulated coexistence of conventional/organic farms and users of biotechnology. Excessive liability of farmers can be avoided, if the producers of genetically modified seeds accept any litigation claims against farmers. Furthermore, negotiations between neighbouring farms can be an option to keep the costs of damage prevention at reasonable levels.

With the coming-into-effect of regulation (EC) Nr. 510/06 from the 20th March 2006 and the executive regulation (EG) Nr. 1898/06 the community-wide protection of geographical indications and designations of origin for agricultural products and foods received a new legal basis. The new regulation replaces the old regulation (EG) Nr. 2081/92. Because some of the changes have great significance for new applications of producer groups and for their communication policy in this paper the most important modifications will be presented and evaluated. Furthermore proposals for possible future modifications are discussed.
Mehr-Ebenen-Modelle in der Analyse agrarstruktureller Entwicklungen – Methodik und Implikationen
Authors: Margarian Anne
Published: August 2024

Until now empirical analyses have not succeeded in the determination of a general upon agreed bunch of the most important driving forces of structural change in agriculture beyond the level of the national economy. It will be argued that the sometimes contradictory results of different studies are caused by the endogenous dynamics of structural change as well as by mixing up different levels of causality. The influence of single causes, therefore, is not necessarily characterised by linearity, symmetry and independence of other causes, of the location or of time. Multi-level-models are being presented as a method with the capability to cope with these problems by modelling hierarchical relations and dynamics in time simultaneously. The flexibility of the method as well as its capability to generate new insights will be demonstrated on the example of a panel analysis for the explanation of regional differences in structural change of agriculture.
Modellgestützte Abschätzung der regionalen landwirtschaftlichen Landnutzung und Produktion in Deutschland vor dem Hintergrund der „Gesundheitsüberprüfung“ der GAP
Authors: Kreins Peter , Gömann Horst
Published: August 2024

The framework conditions surrounding agricultural production in Germany have changed dramatically due to the Renewable Energy Law (EEG) and a sustained increase in agricultural prices. The Common Agricultural Policy, substantially reformed in the Luxemburg Compromise, will be considered in the framework of the “Health Check”. Against this background, the regional developments anticipated in dairy production, beef cattle husbandry and agricultural land use by the year 2015 are analysed with the help of the regionalized agricultural sector model RAUMIS. Simulations on the adaptability of dairy production under different market conditions are carried out with regard to the expiration of the dairy quota regulation. The farming intensity on arable land is generally increasing due to the increase in agricultural prices, the elimination of set aside obligation and the promotion of renewable resource crops. The increasing competitiveness of cash crops is speeding the departure of dairy production from arable crop areas into competitive grassland regions. In contrast, milk production is either constant or reduced on less competitive grassland locations. Among the regions reducing production are, according to the model results, low mountain ranges with high levels of grassland, for example in the Black Forest, in the Schwäbisch Alp, in the Hessian Mountain area in parts of the Eifel and parts of the Hunsrück. In the course of the many decades of milk quota system, a significant milk production potential was deactivated which could play a large role when the quota regulations expire. Based on a calculated “milk equilibrium price” at which the quota amounts are exactly produced, a price increase of ten percent leads to a long term expansion of the milk produced by about six million tons. There is thus no reversal of the successive milk production reductions in the least competitive regions, not even through significantly higher direct payments distributed in the framework of the introduction of the “regional model” in grassland regions, since these are decoupled payments. Should this drop in milk production have negative consequences for other sectors, for example tourism, it is to question, whether specific measures should be developed for the affected regions.
The influence of climate change, technological progress and political change on agricultural land use: calculated scenarios for the Upper Danube catchment area
Authors: Henseler Martin , Wirsig Alexander , Krimly Tatjana , Dabbert Stephan
Published: August 2024

Both climate and agricultural policy changes are commonly seen as important drivers for agricultural production. In this study, scena-rios of climate and political change were calculated for the Upper Danube catchment area using the regional optimization model ACRE. Two political scenarios were calculated for the year 2020. One scenario assumes the continuation of the Common Agricultural Policy reform 2003 the other assumes a strong shift away from payments of the first pillar to payments of the second pillar of the CAP. Both scenarios were combined with four different scenarios of climate change and technological progress derived from ICCP SRES assumptions and the ACCELERATES project. The results of the scenario calculations were analysed with respect to their implica-tions for the whole catchment area as well as for selected districts. Climate change and technological progress both cause small changes in agricultural land use: fodder crop area tends to be converted to cash crop area, and intensive grasslands tend to be converted into extensive grasslands. Climate change and technological progress increase crop productivity, and consequently, total gross margin increases. The impact of climate change might get stronger toward the end of the century which is beyond the scope of the investigations presented here. The impact of climate change might thus switch from bringing net benefits in the short to medium term to bringing net losses for the area investigated in the long run.

The didactic value of linking models: experiences from the LEI model funnel
Authors: Helming John F.M. , Banse Martin
Published: August 2024

The complexity of agri-environmental economic issues is such that a model that is fully consistent at all levels of aggregation and all type of questions to be addressed is not available at the Agricultural Economics Research Institute in the Hague LEI. Such a model is probably also not feasible. At LEI this problem is solved by linking models at different scales of analysis: global economic, national economy-wide, regional agricultural, national spatial and farm levels. This linked model system enlarges scope and consistency of the analysis. The goal of the model linking, however, is not a full integration and, ultimately, simultaneous optimization of the models. Therefore, the different models of the LEI model funnel are often rather loosely linked. Hence, it is not surprising that the models sometimes produce different results even for the shared variables. This article describes the difficulties to share and exchange information between different models and identifies possible solutions which aim at a more consistent analysis along the models combined at LEI while maintaining the diversity of modelling approaches.

Zusatznutzen Berg? Argumente für den Konsum von Bergprodukten
Authors: Matscher Anja , Schermer Markus
Published: August 2024

Given the broad range of products in food retailing, actors are increasingly aiming to differentiate their products by promoting certain features as added benefits. This means that any added (emotional) benefit, whichever way it is communicated, becomes significant. In this article we investigate inhowfar the fact that a product originates from a mountain region constitutes such an added benefit for consumers and what arguments support their choice of mountain food products. We present results of four focus groups with participants from Austria (Tyrol) and Germany, analysed by using Convention Theory. Our findings suggest that the origin of a food product in a mountain region does not constitute a singular added benefit but rather the sum of several components associated with a mountain origin, in varying combinations, depending on the specific focus group. The statements gathered in the focus groups may thus provide some indication on how to improve the communication strategy for mountain products.
Consequences of a progressive reduction of direct payments in Germany: paving the way for post-2013?
Authors: Kellermann Konrad , Sahrbacher Amanda , Sahrbacher Christoph , Balmann Alfons
Published: August 2024

Due to Germany’s specific farm structure, the progressive modulation of direct payments decided within the Health Check of the Common Agricultural Policy (CAP) is of particular relevance for German agriculture. In this paper we apply the agent-based model AgriPoliS to shed some light on the structural effects of a progressive modulation as evoked in the Health Check (HC) proposal and the final agreement made in November 2008 for two German regions. Furthermore, we analyse whether a progressive modulation will allow for a continuous policy in the case of a reduced hypothetical single area payment of 150 €/ha starting in 2013. Results show that although we could observe substantial income effects in the short and long run, structural effects of the progressive modulation scheme are small but preservative. In contrast, the introduction of a reduced single area payment in 2013 would sharply increase structural change. In case the initial HC proposal is followed by a single area payment the previously observed policy effects would diminish for very large (above € 300,000 premium) and small farms (below € 100,000 premium). Still, although these effects are much less pronounced with the final HC agreement, the progressive modulation would provide farmers with wrong signals, as it is most likely that future reforms will be characterized by less support and thus require a stronger market orientation of farms.
The Europeanisation of agri-environmental policy in Poland
Authors: Hadyńska Anna
Published: August 2024

This paper seeks to answer the following question: what are the impacts of European agri-environmental policy (AEP) on member states’ policy patterns? The concept of Europeanisation is employed, as it relates to the adaptation of domestic policies and policy instruments to existing EU legislation. An analysis of the extent to which the European level of policy-making has affected the emergence and further development of the AEP in Poland will be undertaken. Additionally, the paper examines the way in which Poland has applied Agri-environmental Schemes (AESs) and what effects this has had on the relevant Polish institutions. Empirically, this research draws on semi-structured interviews with key administrative bodies and social actors involved in agri-environmental issues.
Thuenen Rings of Biogas Production – the Effect of Differences in Transport Costs of Energy Crops in the Choice of Renewable Resources by Biogas Plants
Authors: Schulze Steinmann Matthias , Holm-Müller Karin
Published: August 2024

This paper discusses how differences in transport costs of energy crops affect the choice of feedstock used in biogas production. This is done by optimizing feedstock demand subject to transportation distances of the different crops. For this a von Thuenen type model is applied to the feedstock demand of biogas plants. In addition to yields in terms of quantity and energy concerning the different crops and the costs of having them available, the profitability of the fermentation plant must be considered. It is shown that silage maize is the most profitable crop for medium distances, but gives way to winter wheat as distances increase. Our analysis suggests that even bigger plants than today can be sustained exclusively with silage maize. Key words: Thuenen Rings; transportation logistics; energy crops; biogas production

Does Strategic Group Membership Affect Firm Performance? An Analysis of the German Brewing Industry
Authors: Theuvsen Ludwig , Heyder Matthias , Niederhut-Bollmann Christoph
Published: August 2024

The concept of strategic groups has been successfully applied for analyzing firm strategies, structures and performance in various industries. Based on a large-scale empirical study, this paper identifies strategic groups in the German brewing industry and analyzes the effects of group membership on economic performance. The brewing industry is an interesting research object. The severe economic crisis German breweries face in their home market and the deep structural changes reshaping the global beer industry are forcing German breweries to rethink their strategic position. The analysis reveals a limited number of strategic groups and significant performance differences between these groups. Both results are in line with the central hypotheses of the concept of strategic groups. The empirical results enable firm managers to benchmark their breweries against more successful strategic groups, to better adapt corporate and competitive strategies to firm environments, to identify more profitable strategic positions, and to take action to switch from one strategic group to another.
Impacts of Stockholding Behaviour on Agricultural Market Volatility: A Dynamic Computable General Equilibrium Approach
Authors: Femenia Fabienne
Published: August 2024

Successive CAP reforms raise the question of whether it can have a price-stabilizing capability. In this context more and more attention is being paid to private risk-managing instruments such as storage. The effects of storage have already been widely studied in the economic literature. But hardly any of these studies take account of the links between producers’, households’ and stockholders’ intertemporal decisions and, in particular, they do not use a dynamic CGE model. Furthermore, a large number of previous studies focus on the effect of stockholding on price volatility due to exogenous shocks and assume rational expectations. It is more the endogenous aspect of risk, induced by expectation errors, that has often been used to justify public intervention in agricultural markets. In this paper we construct a model addressing these issues and we conduct some illustrative simulations. Some of our results are at variance with the conclusions of previous economic studies concerning the effects of speculative storage on market volatilities. We also reveal the vital role played by the form of economic agents’ expectations and by the links between the intertemporal decisions of market participants.

Quantifying the Influence of Product Design on Perceived Taste and Purchase Intent for Wine Using a Characteristics Model
Authors: Szolnoki Gergely Szolnoki , Hoffmann Dieter , Herrmann Roland
Published: August 2024

A substantial expansion of wine supply has induced a strong product proliferation on the market. It is not only the taste of wines that has become more diversified, but quality signals are increasingly utilized, too. Quality signals include information on the wine bottle, such as origin, grape variety or brands. Additionally, there is a strong trend towards using the product design, i.e. bottle type or style of the wine label, as an instrument of product differentiation. The objective of this article is to analyze whether the product design affects the perceived taste of wine and the willingness to buy a wine. Primary data, which have been collected from an experiment combined with a survey of wine consumers, reveal that product design strongly affects the willingness to buy a wine. This strong effect occurs when the wine is tasted prior to the purchase decision. Interestingly, the product design affects consumers’ taste evaluation of the wine that is crucial for the consequential effects on the willingness to buy. An alternative modeling approach with a direct impact of product design on willingness to buy strongly underestimates the role of product design. A cluster analysis additionally reveals that product design and other quality signals do matter in some wine consumer segments but less in others.
Determinants of Competitiveness of „Extended Family Farms“ – Empirical Results from a Survey of Farm Managers
Authors: Schaper Christian , Deimel Mark , Theuvsen Ludwig
Published: August 2024

Due to an intensifying competition, gaining and sustaining competitive advantages have become increasingly important for family farms in recent years. In the course of general structural changes in agriculture, so-called “extended family farms” have emerged as a predominant form of farming businesses in many, mainly western parts of Germany. Through combining traditional family-labour-based governance structures with additional non-family labour, extended family farms can realize economies of scale. Thus, they are often considered a sustainable type of organisation that is able to cope with international competition. So far existing research has not fully explored the factors determining the competitiveness of extended family farms. Against this background, this article analyzes potential determinants of competitiveness of extended family farms on the basis of a survey of 103 farm managers. The empirical results show that the success of the farms surveyed is not only based on the realization of technical economies of scale, but also on the personality of the farm managers and the strategies implemented.
Does the Consumer Really Knows which Quality he Buys? A Study about the Expected Quality from Quality Labels
Authors: Kubitzki Sabine , Krischik-Bautz Stephanie
Published: August 2024

Quality labels for food products are an important consumer policy tool and are used for product diversification strategies by the producers. In the literature, the effectiveness of such labels concerning the purchase behaviour of consumers has been doubted. In this context, our paper compares the guaranteed quality of three labels – QS, CMA and BIO – with their expected quality by the consumer. The QS label and particularly the BIO label are process-orientated and characterized by a high level of control and sanctions. The CMA label assured, till its termination in 2009, a specific sensory quality accompanied with less rigorous mechanisms of control and sanctions. The results of a representative online survey indicate that consumers expect the same quality level from the CMA label and the QS label, although, in fact, QS guarantees a higher process quality. The CMA label can differentiate from the others in consumers’ perception as a regional origin label, whereas the BIO label stands out for the material dimension of quality including safety and quality items. To conclude, the perception of the material quality of labels (e.g. CMA label) can be biased by positively valued ideational product attributes. Thus, it is supposable that the consumer assesses the quality better than it actually is.

Influencing the Effect of Nutritional Information by Framing: Analysis using the Example of Folic Acid
Authors: Lensch Kathrin , Hartmann Monika , Simons Johannes
Published: August 2024

One way to support consumers in integrating health aspects into their purchase and eating behaviour is to make information available to consumers in a comprehensible manner. In behavioural economics framing effects are acknowledged as important factors influencing perception of information. In this paper framing effects are analysed by means of an experiment using the example of information about folic acid. The results give evidence that framing influences consumers’ perception, the need for information and decision process even though the effect is small. Overall, a negative frame results in a stronger effect than a positive one.

A Cohort Analysis of Food-at-Home and Food-away-from-Home Expenditures in Germany
Authors: Drescher Larissa S. , Roosen Jutta
Published: August 2024

Over the last decades and across countries, eating patterns have changed in favour of increasing consumption of food away from home. According to Ando and Modigliani (1957), consumers pass through different stages of a life-cycle with different impacts on demand. The criticism that life-cycle theory neglects generational effects and concentrates only on ageing effects has led to the application of the cohort analysis, which decomposes not only age, but also period and cohort effects. This paper presents the results of a cohort analysis on food-at-home and food-away-from-home consumption covering 25 years of German consumption data. The results of seemingly unrelated regressions indicate that there are significant age, period and cohort effects on food-at-home and food-away-from-home expenditures, which are more distinct for food-at-home consumption. This paper also finds evidence for the significant effects of gender, occupation, household composition and region on both expenditure categories. For instance, the effect of being female is negative on both types of expendi-tures. Moreover, there is a non-linear relationship between household size and both food-at-home and food-away-from-home-consumption.

The Profitability of Seasonal Mountain Dairy farming in Norway
Authors: Asheim Leif Jarle , Lunnan Tor , Sickel Hanne
Published: August 2024

In this paper the economics of seasonal production of cheese in the mountain in Norway is investigated and compared with keeping the cows at the farm, investing in a common pasture or in co-operative dairy farming. The comparison is based on calculations in a linear programming (LP) farm model supported with Stochastic Dominance with Respect to a Function (SDRF) for risk analysis. Mountain dairy farming involves free ranging cows on natural pastures for about 70 days. The contents of polyunsaturated fatty acids, CLA and various antioxidants in the milk increase when cows graze alpine pastures affecting its processing properties, and flavor and chemical content of dairy products. Seasonal mountain cheese production is found to be generally preferable to the other alternatives for risk neutral as well as risk-averse decision makers. This is due to a higher price for mountain products, subsidy payments for mountain farming, and exemption for farm processed milk in the national milk quota. The risks are partly price risks but also yield and output risks as well as downside political risks since the profitability depend strongly on subsidies and premiums, and exemption for farmprocessed milk in the milk quota. Investments in farming co-operatives were unprofitable due to less subsidy payments compared to individual farmers. Effects of calving time, introducing fertilized pastures or night pens, and supplementary feeding to extend the mountain period and sustain milk yields are examined. The premium price for “mountain products”, animal welfare, and farmer co-operation on marketing are discussed.
Determining Short Term Responses of Irish Dairy Farms under Climate Change
Authors: Shrestha Shailesh , Hennessy Thia , Abdalla Mohamed , Forristal Dermot , Jones Michael B.
Published: August 2024

This study aimed to determine short term farm responses of Irish dairy farms under climate change. The Irish National Farm Survey data and Irish weather data were the main datasets used in this study. A set of simulation models were used to determine grass yields and field time under a baseline scenario and a future climate scenario. An optimising farm level model which maximises farm net income under limiting farm resources was then run under these scenarios. Changes in farm net incomes under the climate change scenario compared to the baseline scenario were taken as a measure to determine the effect of climate change on farms. Any changes in farm activities under the climate run compared to the baseline run were considered as farm’s responses to maximise farm profits. The results showed that there was a substantial increase in yields of grass (49% to 56%) in all regions. The impact of climate change on farms was different based on the regions. Dairy farms in the Border, Midlands and South East regions suffered whereas dairy farms in other regions generally fared better under the climate change scenario. For a majority of farms, a substitution of concentrate feed with grass based feeds and increasing stocking rate were identified as the most common farm responses. However, farms replaced concentrate feed at varying degree. Dairy farms in the Mid East showed a move towards beef production system where medium dairy farms in the South East regions shifted entire tillage land to grass land. Farms in the South East region also kept animals on grass longer under the climate change scenario compared to the baseline scenario.

Are Agri-food Exports any Special? Exchange Rate Nonlinearities in European Exports to the US
Authors: Fedoseeva Svetlana
Published: August 2024

Using aggregated EMU exports to the US as an example, VERHEYEN (2013a) showed, that in the long run exports react to exchange rate changes in a nonlinear way. This paper tests whether this holds true for agri-food exports as well. To address this question a partial sum decomposition approach and the NARDL framework of SHIN et al. (2013) is applied to the aggregated agri-food exports of eleven European countries to the US, which is currently the major partner of the EU in agricultural trade. The outcomes suggest, that the exchange rate nonlinearities are even more pronounced in agri-food than in total exports. European exporters seem to benefit more from Euro depreciation, than its appreciation harms them. These findings might be interpreted as a sign of pricing strategies application (e.g., pricing-to-market) to the European agri-food exports.

Evaluating the Land Conversion of Annual Crop Production to Cultivate Miscanthus – An Application of the Real Options Approach
Authors: Diekmann Antonius , Haverkamp Matthias , Mußhoff Oliver
Published: August 2024

Several studies applying the classical investment theory have shown that miscanthus (MSC) is an economically advantageous alternative to traditional agricultural land use. Nevertheless, only few farmers cultivate MSC. Therefore, it seems as if farmers do not act according to classical investment theory. In contrast to the classical investment theory, the real options approach (ROA) considers irreversibility and temporal flexibility of an investment as well as uncertainty with regard to investment returns. Consequently, investment triggers indicating when a decision-maker should invest can be shifted upwards in comparison to the classical investment theory. It is therefore often concluded that the ROA can help to explain investment restraint. However, the possibility of disinvestment is often neglected. Thus, there is the risk that calculated investment triggers of the ROA are overestimated. We develop a model by using a combination of a genetic algorithm and stochastic simulation in order to calculate investment triggers in general, and conversion triggers in particular (with and without reconversion possibilities) to the conversion possibility from wheat to MSC following the ROA. Our results show that the conversion triggers of the ROA are higher than those of the classical investment theory. Nevertheless, the neglection of disinvestment (reconversion) possibilities leads to overestimating conversion triggers. However, conversion triggers of the ROA are still higher than those of the classical conversion triggers of both theories decrease. It can be concluded that the ROA has the potential to partially explain farmers' inertia to convert to MSC.

Biofuel Sustainability Requirements – The Case of Rapeseed Biodiesel
Authors: Junker Franziska , Gocht Alexander , Marquardt Sandra , Osterburg Bernhard , Stichnothe Heinz
Published: August 2024

Biodiesel production in Europe and Germany relies heavily on rapeseed oil. Thus, the biodiesel industry has become the most important outlet for rapeseed oil. In light of the increasing greenhouse gas (GHG) saving requirements at the European level, this situation may change: according to the default values specified in the current legislation, biodiesel produced from rapeseed oil will not meet GHG saving requirements as of 2017. In this article, we assess the market impacts of the withdrawal of rapeseed oil from the biodiesel industry in Germany and Europe. Simulations with the MAGNET and CAPRI modelling systems indicate a decline in producer prices for rapeseed of approximately 17% in the EU. The area dedicated to rapeseed production will decline by 6%. Rapeseed oil is primarily substituted by imported vegetable oils. Simultaneously, imports of biodiesel from North America, Argentina and Asia are projected to increase. We investigate options to improve the GHG balance of rapeseed biodiesel. We conclude that only a combination of climate-friendly produced fertiliser and efficient conversion processes can provide the necessary GHG emission-savings to meet the EU’s sustainability goals after 2017.

Is the Cultivation of Sugar Beets as a Biogas Substrate an Alternative for Farmers? A Discrete Choice Experiment for the Design of Substrate-supply-contracts for Sugar Beets
Authors: Sauthoff Saramena , Anastassiadis Friederike , Mußhoff Oliver
Published: August 2024

In order to provide a sustainable renewable energy production in biogas plants, it is necessary to examine substrates apart from silage maize on their suitability and acceptance in society. In this context, sugar beets gain more and more importance for the production of biogas. To date, there have not been any studies on the attitude of farmers towards the alternative use of sugar beets in biogas plants. We, therefore, investigated how substrate supply contracts should be designed that farmers agree to cultivate sugar beets for biogas. Due to the lack of farm-level data, we conducted an online-survey including a Discrete Choice Experiment with 118 German farmers. Our results show that the participating farmers react with re-straint to contract sugar beets for biogas. If farmers opt for a supply contract of beet as biogas substrate, they prefer a short contract period and small-scale cultivation. A spring harvest of sugar beets is generally rejected.
The Use of Silage Maize for Biogas Production – A Spatial Econometric Approach
Authors: Scholz Lukas , Meyer-Aurich Andreas , Kirschke Dieter
Published: August 2024

The expansion of silage maize production has experienced a dynamic development in recent years. This happened against the background of continuously decreasing cattle numbers and a rapid increase in biogas production. Available information on actual cultivated land with silage maize for biogas production in Germany diverges due to different methods of calculation between 500 000 ha and 1 800 000 ha for the year 2010. Based on the spatial econometric models developed in this study, estimates of the use of silage maize in biogas production and dairy and cattle farming are given for the state of Bavaria. The average estimated share of silage maize of agricultural land in Bavaria is 4.5 % for biogas production and 7.2 % for dairy and cattle farming. About 40 % of total production of silage maize is used for energy purposes on average. Further, the results of the study allow for a spatially differentiated view on the use of silage maize for biogas production.

Genetically Modified Herbicide Resistant Rapeseed in Germany: A Socio-Economic Assessment
Authors: Wree Philipp , Sauer Johannes
Published: August 2024

The cultivation of transgenic rapeseeds is currently banned in Germany. Considering the reversibility, irreversibility and uncertainty in the context of costs and benefits of introducing herbicide-resistance rapeseeds (HR), we determine the maximum incremental social tolerable irreversible costs (MISTICs) of this technology for Germany. Results indicate that banning HR genetically modified
