Coffee has proven to be highly sensitive to climate change. Because coffee plantations have a lifespan of about thirty years, the likely effects of future climates are already a concern. Forward-looking research on adaptation is therefore in high demand across the entire supply chain. In this paper we seek to project current and future climate suitability for coffee production (Coffea arabica and Coffea canephora) on a global scale. We used machine learning algorithms to derive functions of climatic suitability from a database of geo-referenced production locations. Use of several parameter combinations enhances the robustness of our analysis. The resulting multi-model ensemble suggests that higher temperatures may reduce yields of C. arabica, while C. canephora could suffer from increasing variability of intra-seasonal temperatures. Climate change will reduce the global area suitable for coffee by about 50 % across emission scenarios. Impacts are highest at low latitudes and low altitudes. Impacts at higher altitudes and higher latitudes are still negative but less pronounced. The world’s dominant production regions in Brazil and Vietnam may experience substantial reductions in area available for coffee. Some regions in East Africa and Asia may become more suitable, but these are partially in forested areas, which could pose a challenge to mitigation efforts.

The nitrogen pollution of freshwater heavily affects social–ecological systems. To reduce negative effects, research calls for an integrated approach, including a coherent and diverse set of governance instruments. Thus far, however, the effects of (non-)integration have been blurry. Taking Germany as an example, this study sheds light on the actual complexity of the problem along five dimensions of complexity (goals, variables, dynamics, interconnections, and uncertainties). It also sheds light on related governance instruments (rules, information, and economic incentives) and their impacts on problem-solving (implementation of specific measures). Analyses include expert interviews on complexity, European water and agricultural policies, and official data on the planning and implementation of measures to reduce nitrogen concentrations. Results show Germany’s path of sustaining a complex problem by using a non-coherent and low diversity governance approach, avoiding rigorous rules, and barely using economic instruments to deal with nitrogen surpluses. A stronger integration of water and agricultural policies, as well as a better use of economic instruments, are suggested to enhance water quality in the future.

Agricultural land use in Germany is faced with new drivers and conflicts. There has been a continuous downward trend in agricultural land use since reunification, and agriculture seems to be increasingly squeezed by various land use demands. Whereas land prices and land rents have stayed rather stable during the 90ies and at the beginning of the new millennium, they have started to go up considerably during the last ten years. At the same time the agricultural sector is faced with deteriorating environmental indicators and a changing land use structure and concentration. International agricultural prices have become a key determinant for land prices in Germany contributing to increasing land prices. Equally, new demands for nature conservation and natural resource protection under the Common Agricultural Policy have contributed to make agricultural land scarcer, and bioenergy production under the Renewable Energy Act has considerably affected land demand and prices in various regions. In East Germany, some land market specialties relate to the farm structure and the land privatization process after reunification. In view of these developments, there is a new policy debate on agricultural land market interventions.

The use of nitrogen (N) fertilizer substantially contributes to greenhouse gas (GHG) emissions due to N2O emissions from agricultural soils and energy-intensive fertilizer manufacturing. Thus, a reduction of mineral N fertilizer use can contribute to reduced GHG emissions. Fertilizer tax is a potential instrument to provide incentives to apply less fertilizer and contribute to the mitigation of GHG emissions. This study provides model results based on a production function analysis from field experiments in Brandenburg and Schleswig-Holstein, with respect to risk aversion by calculating certainty equivalents for different levels of risk aversion. The model results were used to identify effective and cost-efficient options considering farmers’ risk aversion to reduce N fertilizer, and to compare the potential and cost of GHG mitigation with different N fertilizer tax schemes. The results show that moderate N tax levels are effective in reducing N fertilizer levels, and thus, in curbing GHG emissions at costs below 100 €/t CO2eq for rye, barley and canola. However, in wheat production, N tax has limited effects on economically optimal N use due to the effects of N fertilizer on crop quality, which affect the sale prices of wheat. The findings indicate that the level of risk aversion does not have a consistent impact on the reduction of N fertilizer with a tax, even though the level of N fertilizer use is generally lower for risk-averse agents. The differences in N fertilizer response might have an impact on the relative advantage of different crops, which should be taken into account for an effective implementation of a tax on N fertilizer.

This study analyzes the greenhouse gas mitigation potential and corresponding mitigation costs of biogas production in the federal state of Brandenburg, Germany. The production of biogas is based on cattle slurry and maize (Zea mays L.) and is used to produce electrical and thermal energy. The impacts of the feedstock and storage facilities chosen, thermal energy use, and land use change on the mitigation potential and the mitigation costs were analyzed by evaluating different scenarios.

A conceptual framework for climate change assessments of international market systems that involve long-term investments is proposed. The framework is a hybrid of dynamic and static modeling. Dynamic modeling is used for those system components for which temporally continuous modeling is possible, while fixed time slices are used for other system components where it can be assumed that underlying assumptions are held constant within the time slices but allowed to vary between slices. An important component of the framework is the assessment of the "metauncertainty" arising from the structural uncertainties of a linked sequence of

Clinical trials on fracture repair have challenged the effectiveness of bone morphogenetic proteins (BMPs) but suggest that delivery of mesenchymal stem cells (MSCs) might be beneficial. It has also been reported that BMPs could not increase mineralization in several MSCs populations, which adds ambiguity to the use of BMPs. However, an exogenous supply of MSCs combined with vascular endothelial growth factor (VEGF) and BMPs is reported to synergistically enhance fracture repair in animal models. To elucidate the mechanism of this synergy, we investigated the osteoblastic differentiation of cloned mouse bone marrow derived MSCs (D1 cells) in vitro in response to human recombinant proteins of VEGF, BMPs (-2, -4, -6, -9) and the combination of VEGF with BMP-6 (most potent BMP). We further investigated ectopic bone formation induced by MSCs pre-conditioned with VEGF, BMP-6 or both. No significant increase in mineralization, phosphorylation of Smads 1/5/8 and expression of the ALP, COL1A1 and osterix genes was observed upon addition of VEGF or BMPs alone to the cells in culture. The lack of CD105, Alk1 and Alk6 expression in D1 cells correlated with poor response to BMPs indicating that a greater care in the selection of MSCs is necessary. Interestingly, the combination of VEGF and BMP-6 significantly increased the expression of ALP, COL1A1 and osterix genes and D1 cells pre-conditioned with VEGF and BMP-6 induced greater bone formation in vivo than the non-conditioned control cells or the cells pre-conditioned with either VEGF or BMP-6 alone. This enhanced bone formation by MSCs correlated with higher CADM1 expression and OPG/RANKL ratio in the implants. Thus, combined action of VEGF and BMP on MSCs enhances osteoblastic differentiation of MSCs and increases their bone forming ability, which cannot be achieved through use of BMPs alone. This strategy can be effectively used for bone repair.

Planning agricultural and environmental programmes has become a complex task. In this paper we show how interactive programming can help to solve such complex policy decision-making problems. The basic linear programming model is implemented with Excel. We show, for a hypothetical agricultural and environmental programme, how the approach can be used in an interactive way between scientists and policy decision-makers. The approach allows to visually demonstrate and quickly assess the consequences of changing assumptions and framework conditions on the programme design. It could effectively improve the quality of policy decision-making support; it requires the actors’ willingness, of course, to engage in a real dialogue.

In this paper we analyse the impact of the EU multi-level co-financing system on regional policy-making and priority setting taking the case of the agri-environmental programme of Saxony-Anhalt. The implications of several co-financing scenarios are analysed and compared to respective lump-sum transfers using an interactive linear programming approach. The results reveal how regional choices on agri-environmental measures are influenced by the co-financing system leading to distortions. The extent of these distortions depends on the specific regional preferences and restrictions.

This article focuses on the social rate of return to plant breeding investment in Germany between 1980-2000. Starting point of the analysis is the development of total factor productivity which is decomposed into the effects of factor input and research investment. Information on investment in plant breeding have been obtained via questionnaires sent to both private plant breeding companies and public research organizations. The empirical results suggest significant underinvestment in German plant breeding research, as the calculated social rate of return is in the range of 16 to 28%.

Abstract “Swelling” is generally taken to mean the expansion of a rock due to water absorption. The main intention of this paper is to point out the significant difference between the swelling of clay and claystone (Tonstein) on one hand and the swelling of claystone and marl containing anhydrite on the other. In the opinion of the author, these differences are so large that they should be described as different phenomena. Leopold Müller has already proposed the introduction of different German terms: “Quellen” for clay and “Schwellen” for anhydrite. Unfortunately, this terminology has not caught on, probably because the word swelling is used in English for both processes. The resulting merging has hindered research into anhydrite swelling for decades, and the development of calculation methods and technical solutions for tunnelling in anhydrite‐bearing ground is still at an early stage. In contrast, the problem of clay swelling can be regarded as largely solved. Unter “Quellen” wird ganz allgemein die Ausdehnung eines Gesteins infolge von Wasseraufnahme verstanden. Hauptanliegen des vorliegenden Beitrags ist es, auf die beträchtlichen Unterschiede zwischen Quellvorgängen in Ton und Tonstein einerseits und in anhydrithaltigem Ton‐ und Mergelstein andererseits hinzuweisen. Nach der Überzeugung des Autors sind die Unterschiede so groß, dass man eigentlich von zwei verschiedenen Phänomenen sprechen muss. Schon Leopold Müller hat deshalb getrennte Begriffe einzuführen versucht: “Quellen” für Ton und “Schwellen” für Anhydrit. Bedauerlicherweise hat sich diese Terminologie nicht durchsetzen können, vermutlich auch wegen der Verwendung des Worts “swelling” in der englischen Sprache für beide Vorgänge. Die damit verbundene Gleichsetzung hat jahrzehntelang die Erforschung des Anhydritschwellens behindert. Die Entwicklung von Rechenansätzen und von technischen Lösungen für Tunnel in Anhydritgestein befindet sich letztlich immer noch in einer Frühphase. Dagegen kann das Problem des Tonquellens als weitestgehend gelöst angesehen werden.

Das neue Bild des Strukturwandels im Agrarsektor wird geprägt durch eine Vielfalt wirtschaftlicher, politischer und institutioneller Veränderungsprozesse. Die gesellschaftlichen Ansprüche an den Agrarsektor haben sich gewandelt und sind vielfältiger und komplexer geworden, und der Paradigmenwechsel von einer eher protektionistischen Agrarpolitik zu einer stärker an Umwelt- und Qualitätszielen ausgerichteten Agrarpolitik hat erheblichen Einfluss auf strukturelle Entwicklungen. Zudem werden die strukturellen Veränderungsprozesse entscheidend geprägt durch neue Technologien und Internationalisierungs- und Globalisierungsprozesse. Von 2003 bis 2006 arbeitete an der Humboldt-Universität eine von der DFG geförderte Forschergruppe zu Fragen des Agrarstrukturwandels in Mitteleuropa. Der Beitrag stellt beispielhaft einige Ergebnisse der Forschungsarbeiten vor und skizziert künftige Arbeiten in dem Forschungsschwerpunkt. Am Beispiel des Agrarsektors geht es um ein neues und vertieftes Verständnis strukturellen Wandels in modernen Volkswirtschaften.

The paper provides a methodology which is suitable for the analysis of the social cost of disease and the benefits and cost of health intervention by integrating public health analysis and economics. The approach developed in the paper is applied to food-borne diarrhea in Rwanda. The results suggest that simple treatments such as Oral Rehydration Therapy have a higher social rate of return than consumer protection via education.

Citizen science is often promoted as having the capacity to enable change–from increasing data provision and knowledge product development, via behavioral change of citizens, to problem-solving. Likewise, researchers increasingly emphasize the role of project design in initiating these changes through citizen science. However, respective claims are mostly based on single case studies and reviews, calling for a systematic comparative approach to understanding the effects of project design on change. Based on a survey of 85 water-related citizen science projects from 27 countries, we analyze the comparative effects of literature-based design principles on project impacts. Factor analysis first reveals three key impact factors which are ‘Data output’, ‘Citizen outcome’, and ‘Impact chain’. Regression analysis then shows that these impact factors are significantly influenced by several design factors, amongst which motivational factors are most prominent. The analysis also shows that design factors are most important for ‘Impact chain’, followed by ‘Citizen outcome’, and ‘Data output’. While design factors only partly explain the overall project effects, the regression results are rather stable and significant when including other potential influencing factors like project responsibility and funding. In sum, the results provide an empirically substantiated and differentiated understanding of citizen science impacts and how these are influenced by project design.

Policies for rural areas have become an important but complex policy field in the European Union`s Common Agricultural Policy. The purpose of this paper is to report on a methodological approach pursued to model the allocation of EAFRD (European Agricultural Fund for Rural Development) funds in Saxony-Anhalt. We show how an interactive programming approach can be developed and used to support our partner Ministry of Agriculture and the Environment. So far, various key elements of the modeling approach have been specified: the definition of all relevant policy measures and funding options, the assessment of impacts on the regional objectives pursued, the definition of relevant lower and upper bounds, and the formulation of co-financing requirements and possibilities. Some first results reveal potentials for policy adjustment. After some more refinements and specifications, the model is to be used interactively with Ministry representatives for scenario calculations to support policy-making and strategy development for rural development in Saxony-Anhalt.

Mit den Luxemburger Beschlüssen vom Juni 2003 wird ein neues Kapitel zur Reform der Agrarpolitik in der Europäischen Union aufgeschlagen. Wie jede Politik in ihrem Bereich hat Agrarpolitik dafür Sorge zu tragen, dass die mit dem Agrarbereich verbundenen gesellschaftspolitischen Ziele erreicht werden. In einem marktwirtschaftlichen System geht es zunächst um die Verbesserung der Wettbewerbsfähigkeit der Landwirtschaft und deren Integration in die internationalen Agrarmärkte. Ebenso wichtig ist es aber auch, den Schutz der natürlichen Umwelt, den Erhalt der Kulturlandschaft und den Tierschutz zu gewährleisten sowie soziale Probleme im volkswirtschaftlichen Strukturwandel abzufedern. Aus diesen Gründen wird der Agrarsektor als ein Wirtschaftsbereich angesehen, den man nicht allein dem freien Spiel der Marktkräfte überlassen kann. Die entscheidende Legitimation der Agrarpolitik liegt also darin, dass mit der landwirtschaftlichen Produktion externe Nutzen und Kosten sowie die Bereitstellung öffentlicher Güter verbunden sind.

Seit 1990 veröffentlicht das United Nations Development Programme (UNDP) den sogenannten Human Development Index (HDI), mit dem der Entwicklungsstand eines Landes beschrieben und verglichen werden kann. Zur Beschreibung von Entwicklung stützt sich der HDI auf nur wenige Indikatoren. Dem gegenüber wird in dieser Arbeit ein faktoranalytischer Ansatz genutzt, um einen Entwicklungsindex für Länder auf der Grundlage einer Vielzahl von Entwicklungsindikatoren zu berechnen. Hierdurch wird es möglich, den Aussagegehalt des HDI auf der Grundlage einer möglichst breiten Informationsbasis einzuschätzen und weiter zu entwickeln. Datengrundlage der Analyse sind insgesamt 30 Entwicklungsindikatoren für 94 Länder. Im Ergebnis zeigt die Analyse, dass das Entwicklungsniveau von Ländern durch zwei Faktoren beschrieben werden kann, die als 'Wohlstand' und 'Partizipation' bezeichnet werden. Die für den HDI genutzten vier Entwicklungsindikatoren gehören zu dem identifizierten 'Wohlstandsfaktor', so dass der HDI im Grunde genommen ausschließlich das Wohlstandsniveau als Entwicklung beschreibt und das mit einer begrenzten Informationsbasis. Demgegenüber wird mit Hilfe der zwei identifizierten Faktoren ein breiter definierter Entwicklungsindex HDIplus vorgeschlagen. Die Berücksichtigung des Entwicklungsfaktors 'Partizipation' führt zu einer teilweise erheblichen Abweichung in der Rangordnung gegenüber dem HDI. Die Analyse mag die alte Diskussion neu beleben, in wieweit Entwicklung ausschließlich durch 'Wohlstand' beschrieben werden kann oder weitere Entwicklungsdimensionen umfassen muss.

Financing agri-environmental programmes in the European Union (EU) takes place in a multi-level system with mixed co-financing and shared financial responsibilities. In this paper we analyse how co-financing influences policy-making in regions taking the case of the agri-environmental programme in Saxony-Anhalt. Using an interactive linear programming approach the implications of several co-financing scenarios are analysed. EU co-financing certainly enhances the financial volume for the agri-environmental programme in Saxony-Anhalt; but as regional policy-making is distorted by the scheme of mixed co-financing as compared to unconditional financial transfers, the priorities for measures vary depending on different EU co-financing scenarios.

Die Preisvolatilitat hat in Deutschland im Zeitraum 1993-2008 fur wichtige Agrarprodukte (Weizen, Gerste und Milch) vor allem aufgrund der Deregulierung der EU-Markte zugenommen. Fur andere Produkte hat sich die Preisvolatilitat in diesem Zeitraum wenig geandert, was vor allem daran liegt, dass das Ausmas der Marktregulierung uber diesen Zeitraum stabil war. Im Rahmen von Simulationen mit dem Agrarsektormodell ESIM wurde gezeigt, dass es aufgrund der starken Weltmarktintegration bei Weizen, Gerste und Raps keinen erlosstabilisierenden Zusammenhang zwischen den Ertrags- und den Preisschwankungen in Deutschland gibt, da das auch in Deutschland masgebliche Weltmarktpreisniveau nicht wesentlich durch das Ertragsniveau in Deutschland determiniert wird. Ein potenzieller Anstieg der globalen Ertragsvariabilitat, der sich langfristig in Folge des globalen Klimawandels einstellen konnte, wurde zu einem Anstieg der Preisvolatilitat fuhren. Forderungen nach einer staatlichen Subventionierung von Ernteversicherungen aufgrund des hohen systemischen Risikos und daraus resultierenden Marktversagens haben in den letzten Jahren zugenommen. Bisher fehlt allerdings der empirische Nachweis dafur, dass das systemische Risiko in seiner Hohe nicht durch marktwirtschaftliche Instrumente und ohne Subventionierung beherrschbar ist.
