Currently, a national TEEB study is being conducted in Germany. However, it lacks an overall estimation of ecosystem service value (ESV) at the national level. In this paper, we estimate the ESV in Germany based on the national land cover data and the unit value transfer method and examine the relationships between ESV and gross domestic product (GDP). The results indicate that the total ESV amounts to 248,895 million US$/yr, accounting for 7.91% of the sum of ESV and GDP. Cropland with 111,704 million US$/yr makes the largest contribution to the total ESV, and the second largest state, Lower Saxony, has the greatest ESV of 60,346 million US$/yr. In addition, a spatial pattern that distinguishes four regions in terms of the relationship between ESV and GDP at the district level is identified. This study illustrates the overall status of ecosystem services at the current point of time in Germany, raises public awareness about the magnitude of these services relative to other services captured in GDP, and implies suggestions for future research and ecological policy.

This paper concerns the net effects of promoting renewable energies on value added and disposable income in Germany, as well as their distribution among regions and income brackets. Since its entry into force, the German Renewable Energy Sources Act (EEG) has stimulated tremendous investments in renewable energy capacities by guaranteeing investors a fixed price per kWh as well as a preferred feed into the grid over electricity from conventional sources. The policy measures are financed by a surcharge on electricity prices. In recent years, a controversy has arisen about potentially negative regional and social distribution effects. In this paper, multiregional price and quantity input-output models with endogenous heterogeneous households are used to trace the indirect impacts of the EEG on value added and disposable income through the complex network of regional value chains. Our findings suggest that the generation of electricity from renewable sources itself leads to small positive impacts on industries, but leads to a significant drain on household income and has regressive distributive effects. However, investment in new capacities may possibly transform these negative impacts into a positive direction for the majority of households. [ABSTRACT FROM AUTHOR]

In many studies, consumer preferences are determined by using direct surveys. For this method social desirability is problematic. This leads to the effect that participants answer in a way that they perceive as desired by society. This leads to the stated importance of certain features in these studies not being reflected in real purchasing decisions. Therefore, the aim of the study is to compare consumer preferences measured by a quasi-experiment to those quantified by direct questions. Another objective is to quantify the part-worth utilities of product characteristics such as origin, price and food labels. Part-worth utilities are estimated on an interval scale with an arbitrary origin and are a measure for preferences. The real purchasing situation was simulated in a quasi-experiment using a choice-based conjoint analysis. The part-worth utilities were then compared with the results of a conventional preference assessment (Likert scale). For this purpose, 645 consumers from all over Germany were surveyed in 2014. The participants were on average 44 years old and 63% were women. The results of the conjoint analysis report the highest part-worth utility (2.853) for the lowest price (1.49€), followed by the characteristic "grown locally" (2.157). For the labels, the German organic label shows the highest part-worth utility (0.785) followed by Fairtrade/"A heart for the producer" (0.200). It is noticeable that the carbon footprint labels have negative part-worth utilities compared to tomatoes without a label (-0.130 with CO2 indication, -0.186 without CO2 indication). The price is ranked 12th in the importance of the characteristics of purchasing tomatoes in the survey with a Likert scale, whereas it is first in the evaluation of the quasi-experiment (conjoint analysis), which supports the assumption of a social desirability bias.

Deliberative monetary valuation has emerged as a promising alternative to conventional stated preference studies of ecosystem services. It promises to give respondents a better basis for decision-making by exposing them to a more diverse set of knowledge, arguments and opinions through group discussion. However, under certain conditions, small groups may fail to effectively pool the individual knowledge of their members. This paper examines the impact of the initial distribution of individual preferences in discussion groups on the outcome of deliberative choice experiments. Drawing on a deliberative monetary valuation study of forest ecosystem services in West Saxony, Germany, it is shown that the initial preference distribution in groups influences both the diversity of arguments exchanged during group discussions and respondents' consideration of the costs of environmental policies. Furthermore, results indicate that respondents' post-discussion willingness-to-pay is affected by the initial preference distribution in groups, though these changes were not statistically significant. The choice certainty of respondents was found to remain largely unaffected. Overall, the empirical findings of this study provide preliminary evidence about the need to conduct future deliberative monetary valuation studies with groups with heterogeneous initial preferences as this may provide respondents with a more complete set of decision-relevant information.

While political and scientific interests in ecosystem services (ES) information increases, actual implementation in planning still remains limited. We investigated how landscape and regional planners in Germany already use environmental information, and explored their perceptions concerning an integration of additional information on ES in their work. Four themes are addressed: (1) existing decision-making contexts, (2) current use of environmental information, (3) perceived options for integrating ES information, and (4) useful ES information formats. The research method consists of semi-structured interviews and a web-based survey with German landscape and regional planners. Results are disaggregated between landscape and regional planners, as well as planners with and without prior knowledge of the ES concept. Our results illustrate that a broad range of environmental information is already used that could be associated with ES, but the two most frequently consulted data, species and habitats, relate more to biodiversity. Stronger integrating ES information in planning was generally perceived as useful. However, implementation would often require a mandate from higher-ranking policy levels and the provision of appropriate resources. Project-oriented planning, public information and regional development were seen as promising application contexts. Contrary to our expectations, planners with prior knowledge of the ES concept did not evaluate the usefulness of ES information significantly more optimistic. No single optimal ES information format (ordinal, cardinal, economic valuation) emerged, but context-specific combinations were proposed. The results present valuable guidance for studies and assessments that aim at addressing the ES information needs and requirements of decision makers, and planners in particular.

Offshore wind farming is a contentious new form of sea use and a prominent driver of change across Europe. Drawing on the results of the research program Zukunft Küste - Coastal Futures, this contribution considers the resilience of the social-ecological system to the introduction of offshore wind farming in a northern German case study region. We do so by focusing on regime shifts and cross-scale effects, described through the concepts of adaptive cycles and ecosystem services. Offshore wind farming is shown to lead to a potential slow regime shift in the marine ecosystem, as well as a more rapid regime shift in the seascape. These shifts lead to changes in the available ecosystem services and conflicts between new and traditional sea and seascape values. We then explore the impact of these changes on the socioeconomic system on the coast. Against the background of the system's current state and constraints, we argue this impact could be creative and innovative, but this trajectory depends on an internal socio-political shift and willingness to change.

In cities there is a variety of economic and spatial forces that may influence to what extent a travel-related CO2 emission pricing can be an effective instrument to contribute to the achievement of CO2 reduction goals. Therefore, we examine the effectiveness and impact of CO2 emission charges using a spatial general equilibrium model of an urban economy, calibrated according to an average German city. Our analyses suggest that the imposition of a Pigouvian type CO2 emission charge on urban passenger travel may be able to reduce emissions by about 1%–11%, depending on the estimated social damage cost of carbon dioxide. Such a policy increases urban welfare mainly on account of a reduction of congestion costs. However, pricing congestion directly not only provides higher urban welfare but also higher emission reductions. Pricing congestion and CO2 emissions simultaneously allows to achieve a wide range of emission reduction goals. If, however, the reduction goal is very ambitious the emission charge must be raised to higher levels. Then, distortions in the urban markets and in spatial travel decisions lower labor supply and thus urban production, income of city residents, federal tax revenue, income of landowners outside the city, all together implying losses in welfare.

The paper assesses the impact of different policy options on the land use and associated biodiversity values of jointly organised low-intensity grazing systems (‘Allmende’) in Bavaria. We use an integrated economic and ecological modelling approach to compare three scenarios with the situation in 2003/05. We base the economic sub-model on single farms, which alter their land use in response to economic stimuli. Within the economic part, factors like the farm's endowment with machinery and quota are regarded. Within the rule-based ecological sub-model we analyse: area of protected habitats according to the EC Habitats Directive; biodiversity for selected taxonomic groups and habitat quality for different target species. An overall evaluation of the scenarios indicates that decoupling has a limited effect, because higher direct payments compensate the effect of lower product prices. If all payments are strictly targeted to agri-environmental measures and set to a level which guarantees a low-input management of the grassland, the public costs could be reduced and additional habitats for the target species could be provided. Regarding all indicators but the extent of protected habitats and the public costs, a scenario with a cessation of public payments and market liberalisation performs the worst.

Abstract: Although frequently referred to in the literature, the concept of cultural ecosystem services (CES) has so far been limited in its application. Difficulties arise when specifying the nature of intangible values, but more significantly when it comes to relating intangible values to ecosystem functions. After setting out some conceptual issues, this paper uses a case study on the German North Sea coast to illustrate ways of operationalising the concept in a marine context. Based on a survey of local residents, we first identify current CES in the sea and the intangible values associated with them. Seascape and place emerge as useful conceptual bridges linking ecosystem functioning outcomes to key CES values. We then relate this to offshore wind farming, which some residents perceive as a significant threat to certain CES. Although the approach presented increases the visibility of intangible ecosystem values, the problem remains that such assessments are temporal, in need of added calibration and do not automatically put intangibles on a par with market ecosystem value.

This paper reports a contingent valuation study to value the economic benefits of a post-mining lake-district in East Germany. Lusatia Region faces serious water scarcity problems as the closure of mining pits in 1990 led to the termination of groundwater discharge into rivers. The water conflict centres around traditional water users whose water demand is no longer met and the rehabilitation of mining pits in form of a new lake-district. Current water allocation policy for the Elbe catchment places lowest priority on filling mining pits with river water, even though freshwater is essential for good lake water quality. Commissioned by the government, this study aims to determine the non-market benefits that would be generated by good water quality in the lake-district in order to re-assess the distribution of water among all water users in the Elbe catchment. Our findings show that the annual non-market benefits of the lake-district is significant and lies between 10.4 and 16.2 million euros.Apart from recreational benefits, people also obtain non-use values for the lake-district. Furthermore, two challenges for CV became apparent: fuzzy future benefits (potential improvement to the regional economy) significantly influenced WTP estimates, and WTP stated by users interviewed on site and at home varied significantly.

Abstract: The differing paradigms of ecological and neoclassical environmental economics have been described in various articles and books and are also embedded in different professional associations. However, we cannot take for granted that the paradigm debates described in the literature are actually mirrored in exactly the same way in the perceptions and opinions of researchers looking at sustainability from an economic perspective. This paper presents empirical results from a German case study on how economists and others involved in sustainability research from different schools of thought think about the issues of sustainability and economics, how they group around these issues, how they feel about the current scientific divide, and what they expect to be future topics of sustainability research. We analyze the data using cluster analysis. Based on a literature survey, we generated forty sustainability economics-related statements and asked 196 sustainability researchers about their degree of agreement or disagreement with these statements. In evaluating our survey results, we discuss to what extent the clusters that we identified do—or do not—represent the two schools of thought of ecological and neoclassical environmental economics. We also propose some fields of research that can help to bridge the gaps amongst sustainability economics researchers while clearly marking others that are more suitable for a scientific ‘competition of ideas’. Key results of the study are: We identify two primary scientific clusters, one clearly confirming the existence of the ecological-economics school of thought, and the other largely capturing the neoclassical environmental view. Yet, there are some surprising exceptions: Both schools of thought share a conceptual definition of sustainability that is integrative in considering ecological, societal and economic dimensions (‘three pillar concept’) and is geared at preserving the development potentials of society. We also find a shared critique of ‘pure economic growth’ strategies in our sample. These shared opinions may provide bridging concepts between the schools of thought. Also both clusters agree with respect to a wide range of future fields of sustainability economics research. Yet, the research agenda of the ecological-economics cluster contains a large number of additional topics, primarily related to social, distributional and evolutionary aspects of sustainable development. Strong divides between the clusters that seem to be more suitable for a scientific competition of ideas are primarily related to the question of how to achieve sustainability, including appropriate environmental policies.

Innovations in the bioeconomy are expected to provide new solutions to major economic, societal and ecological challenges like resource depletion, food insecurity or climate change. However, information about innovation activities in the bioeconomy and its outcomes is scattered and more systematic measurement efforts are useful for policy making to assess its impact and whether objectives are met. This article provides an overview of information needs and data availability for innovation indicators. Furthermore, data for key input and throughput indicators are presented and discussed for the bioeconomy in Germany. The data indicates a rather strong role of Germany for publications and patents. However, the commercial success remains unclear, because of current limitations in information availability about the output and outcome of innovations efforts. Here, the most critical information gap in exist. In order to improve this situation additional data collection such as innovation survey for the bioeconomy would be needed. • Innovation measurement concept for the bioeconomy is proposed. • Germany has significant private and public R&D funding activities in the bioeconomy. • Germany is not specialized in the bioeconomy patents. • Information gaps for the innovation impact prevail.
