Although various research approaches have tackled technological innovations in the last few decades, the specificities and enabling conditions of individual sustainability innovations remain rather unknown. We therefore propose an analytical framework, built on learning from the social–ecological systems and transitions literature. The sustainability innovation framework features four dimensions: context, actors, process and outcomes, which are detailed in 31 variables. We use the sustainability innovation framework to analyze two case studies selected in the Schorfheide-Chorin Biosphere Reserve, Germany. The first refers to technological and organizational innovation in mobility, while the second relates to social and organizational innovation in agriculture. As a result, we highlight commonalities and differences in enabling conditions and variables between the two cases, which underpin the influence of trust, commitment, resource availability, experimenting, learning, advocating, and cooperating for innovation development. The cases further demonstrate that sustainability innovations develop as bundles of interdependent, entangled novelties, due to their disruptive character. Their specificity thereby resides in positive outcomes in terms of social–ecological integrity and equity. This study therefore contributes to transitions studies via a detailed characterization of sustainability innovations and of their outcomes, as well as through a generic synthesis of variables into an analytical framework that is applicable to a large and diverse range of individual sustainability innovations. Further empirical studies should test these findings in other contexts, to pinpoint generic innovation development patterns and to develop a typology of sustainability innovation archetypes.

Zunächst wurde das sogenannte Tourismus Sustainability Satellite Account (TSSA), ein Bilanzierungssystem zur Messung der Nachhaltigkeit des Deutschlandtourismus, das in der vorangegangenen Projektphase erstmalig entwickelt und angewendet wurde, nun mit den aktuell verfügbaren Daten erneut befüllt. Beim TSSA handelt es sich um ein erweitertes Tourismus-Satellitenkonto (TSA) bzw. ein Kennzahlensystem, welches im Wesentlichen auf den statistischen Rahmenwerken der Volkswirtschaftlichen Gesamtrechnungen (VGR) und Umweltökonomischen Gesamtrechnungen (UGR) beruht. Hinzu kommen soziale Indikatoren, die die Nachhaltigkeit der Arbeitsverhältnisse im Tourismus messen. Das TSSA erlaubt somit eine systematische Zuordnung der ökonomischen, ökologischen und sozialen Auswirkungen des Tourismus zu den tourismusrelevanten Wirtschaftszweigen auf nationaler Ebene. Im Ergebnis der TSSA-Aktualisierung zeigt sich, dass der Tourismus in Deutschland weiterhin signifikant zur Wertschöpfung und zur Schaffung von Arbeitsplätzen beiträgt. Rund 3,6 % bzw. 6,1 % der Gesamtbruttowertschöpfung und -beschäftigung standen im Jahr 2019 im Zusammenhang mit dem Tourismus. Die Arbeitsproduktivität im Tourismussektor ist allerdings weiterhin relativ gering. Bei den ökologischen Auswirkungen zeigt sich ein im Vergleich zur letzten Messung (mit Daten von 2015 oder 2016) leicht gestiegener Energieverbrauch bei allerdings zurückgehender Energieintensität. Diese ist im Tourismus ähnlich hoch wie im Durchschnitt der deutschen Volkswirtschaft. Bei den tourismusinduzierten Emissionen von Treibhausgasen (THG) und besonders bei der Emissionsintensität sind ebenfalls Verbesserungen zu beobachten, doch liegt die Emissionsintensität der Tourismuswirtschaft immer noch deutlich über dem volkswirtschaftlichen Durchschnitt. Innerhalb der deutschen Tourismuswirtschaft trägt weiterhin der Verkehrssektor (insb. Flug- und Schiffsverkehr) am stärksten zum Energieverbrauch und zu den THG-Emissionen bei. Dagegen ist der tourismusinduzierte Wasserverbrauch deutschlandweit als eher unproblematisch einzuschätzen. Die Wasserintensität des Tourismus liegt deutlich unter dem Durchschnitt der deutschen Volkswirtschaft. Innerhalb des Tourismus ist sie am höchsten in den Sektoren Beherbergung und Gastronomie. Bezüglich der sozialen Nachhaltigkeitsdimension ist der relativ geringe und im Zeitverlauf abnehmende Verdienstabstand zwischen Männern und Frauen (bekannt als Gender Pay Gap; hier unbereinigt) in der Tourismuswirtschaft hervorzuheben. Alle anderen Kennzahlen in Bezug auf die Arbeitsbedingungen im Tourismus fallen dagegen weiterhin eher negativ aus. Dementsprechend werden diese von den Beschäftigten der Branche im Vergleich zum Durchschnitt der deutschen Gesamtwirtschaft als schlechter eingeschätzt. Bereits während der vorangegangenen Projektphase zeigte sich, dass für einige Nachhaltigkeitsindikatoren, vor allem aus dem ökologischen Bereich, eine Berücksichtigung im Rahmen des TSSA-Ansatzes nicht uneingeschränkt möglich ist. Dies liegt unter anderem an der unzureichenden Datenlage in der amtlichen Statistik sowie der Komplexität, bestimmte ökologische Effekte kausal dem Tourismus zuzuordnen. Daher wurde im zweiten Teil des hier vorgelegten Projekts für die Umweltindikatoren „Biodiversität“, „Wasserqualität“, „Lärmbelastung“, „Flächeninanspruchnahme“, „Luftemissionen“ und „Abfallaufkommen“ sowie für den sozialen Indikator „Tourismusakzeptanz“ eine ausführliche Recherche bestehender Datengrundlagen durchgeführt und darauf aufbauend evaluiert, inwieweit alternative Bilanzierungsansätze – als Ergänzung zum TSSA-Messsystem – den Tourismuseffekt abbilden können. Im Rahmen des Datenscreenings bestätigte sich zunächst die mangelhafte Datenlage auf Bundesebene. Die Machbarkeitsanalyse kam nachfolgend zu dem Ergebnis, dass eine räumliche Differenzierung nach dem Grad touristischer Relevanz, gemessen an Tourismusdichte und -intensität, und eine daran anknüpfende Analyse der Veränderung von Umweltbedingungen in stark touristisch geprägten Regionen mit Vergleich zum gesamtdeutschen Durchschnitt eine Möglichkeit darstellt, um den Beitrag des Tourismus beispielsweise zur Flächenversiegelung zu quantifizieren. Einerseits könnte dafür auf bereits bestehende amtliche Regionaldaten zurückgegriffen werden. Andererseits wären bei bestimmten Umweltindikatoren auch zusätzliche Datenerhebungen auf lokaler Ebene in der Zukunft notwendig. Insbesondere für die Wirkungsfelder Biodiversität und Abfälle müssten zunächst die Voraussetzungen bzgl. Datenverfügbarkeit geschaffen werden. Dagegen ließe sich die Tourismusakzeptanz durch regelmäßige standardisierte Befragungen messen. N2 - The project presented here has pursued two main goals. First, the so-called Tourism Sustainability Satellite Account (TSSA), an accounting system for measuring the sustainability of tourism in Germany, which was initially developed and applied in the previous project phase, was repopulated with the currently available data. The TSSA is an extended tourism satellite account (TSA) and indicator system respectively that is essentially based on the statistical frameworks of national accounts (NA) and environmental economic accounts (EEA). In addition, the TSSA includes social indicators that measure the sustainability of labour relations in tourism. The TSSA thus enables a systematic attribution of the economic, environmental and social impacts of tourism to tourism-related economic sectors at the national level. The results of the TSSA update show that tourism in Germany continues to make a significant contribution to value added and job creation. Around 3.6 % of total gross value added and 6.1 % of employment were attributable to tourism in Germany in 2019. However, labour productivity in the tourism sector remains relatively low. In terms of environmental impact, energy consumption in the tourism sector has slightly increased compared to the last measurement (based on data from 2015 or 2016). However, energy intensity has decreased over the same period. Energy intensity in tourism is about as high as for the average of the German economy. Regarding tourism-induced greenhouse gas (GHG) emissions, and particularly emissions intensity, the situation has also improved, even though the GHG emissions intensity of tourism is still well above the average of the German economy. Within the tourism sector, transportation (in particular aviation and shipping) contribute the most to energy use and GHG emissions. By contrast, tourism-induced water consumption appears to be less of a problem in Germany. The water intensity of tourism is significantly lower than the average of the German economy. Within the tourism sector it is the highest in accommodation and gastronomy. In terms of the social sustainability dimension, the relatively low and decreasing income gap between men and women (known as the Gender Pay Gap; unadjusted) in the tourism sector over time is worth mentioning. By contrast, all other indicators regarding the working conditions in tourism continue to perform less favourably. Consequently, employees in the tourism sector still assess the working conditions as worse compared to the average of the overall economy. It has already been shown in the previous project phase that for some sustainability indicators, especially from the ecological dimension, a consideration within the framework of the TSSA approach is not possible without restrictions. This is due, among other things, to the insufficient data available from official statistics and the complexity of causally attributing certain ecological effects to tourism activities. In the second part of the project presented here, a detailed research of existing data bases was therefore conducted for the environmental indicators "biodiversity", "water quality", "noise pollution", "land use", "air emissions" and "waste generation" as well as for the social indicator "tourism acceptance". Based on this, it was evaluated to what extent alternative accounting approaches - as a supplement to the TSSA measurement system - can indicate the tourism effect. The data screening initially confirmed the insufficient data availability at national level. The subsequent feasibility analysis yielded that a spatial differentiation according to the degree of tourism relevance (based on tourism density and intensity) and an ensuing analysis of the change in environmental conditions in regions strongly influenced by tourism in comparison to the overall German average represents an opportunity to quantify the contribution of tourism e.g. to land use. On the one hand, existing official regional data could be used here. On the other hand, additional data collections at the local level would also be essential for certain environmental indicators in the future. In other cases, in particular for biodiversity impacts and solid waste generation, the preconditions for suitable data availability must be created first. By contrast, the acceptance of tourism by residents can easily be measured through standardised surveys.

Human health may be at risk when soils are contaminated; while some soil contaminants such as heavy metals (HMs) have been extensively studied, others such as micro(nano)plastics (MNPs) or antibiotic-resistant bacteria (ARB) pose novel threats. This paper investigates the linkages between soil contamination and human health risk by reviewing the state of knowledge on HMs, MNPs, and ARB in agricultural soils. A keyword-based search in Web of Science, Scopus, and Google Scholar was conducted, complemented with a backward snowball search. We analysed main sources of contamination for agricultural soils, risks to human health differentiated by uptake pathway (ingestion, inhalation, dermal), and interactions of contaminants with microorganism, soil fauna, and plants. Results show that the emergence and spread of ARB and antibiotic resistant genes from agricultural soils and their contribution to antibiotic resistances of human pathogens is recognized as a significant threat. Likewise, a growing body of evidence indicates that MNPs are able to enter the food chain and to have potentially harmful effects on human health. For HM, knowledge of the effects on human health is well established. Multiple agricultural practices increase HM concentrations in soils, which may lead to adverse health effects from the ingestion of contaminated products or inhalation of contaminated soil particles. Severe knowledge gaps exist about the pathways of the contaminants, their behaviour in soil, and human uptake. Little is known about long-term exposure and impacts of MNPs, antibiotics and ARB on human health or about the possible combined effects of MNPs, ARB, and HMs. Missing monitoring systems inhibit a comprehensive assessment of human health risks. Our research demonstrates the need for human health risk assessment in the context of agricultural soils, in particular to be able to assess risks related to measures reinforcing the concept of the circular economy.

T1 - The land and sea routes to 2030: a call for greater attention on all small islands in global environmental policy JF - npj Biodiversity N2 - Islands have unique vulnerabilities to biodiversity loss and climate change. Current Nationally Determined Contributions under the Paris Agreement are insufficient to avoid the irreversible loss of critical island ecosystems. Existing research, policies, and finance also do not sufficiently address small islands’ social-environmental challenges. For instance, the new Global Biodiversity Framework (GBF) mentions islands in the invasive species management target. This focus is important, as islands are at high risk to biological invasions; however, this is the only GBF target that mentions islands. There are threats of equal or greater urgency to small islands, including coastal hazards and overexploitation. Ecosystems such as coral reefs and mangroves are crucial for biodiversity, coastal protection, and human livelihoods, yet are unaddressed in the GBF. While research and global policy, including targeted financial flows, have a strong focus on Small Island Developing States (SIDS), the situation of other small islands has been largely overlooked. Here, through a review of policy developments and examples from islands in the Philippines and Chile, we urge that conservation and climate change policies place greater emphasis on acknowledging the diversity of small islands and their unique governance challenges, extending the focus beyond SIDS. Moving forward, global policy and research should include the recognition of small islands as metacommunities linked by interacting species and social-ecological systems to emphasize their connectivity rather than their isolation. Coalition-building and knowledge-sharing, particularly with local, Indigenous and traditional knowledge-holders from small islands, is needed to meet global goals on biodiversity and sustainable development by 2030.

So far, little is known about how the social and ecological conditions of migration interact. Thus, in our study we investigated the rural-urban migration process from the countryside to the capital in the Eastern Steppe conducting semi-structured interviews. Our results show that this rural-urban migration often follows a stepwise process from smaller settlements to larger urban agglomerations. The results also demonstrate a complex interplay between the prevailing social, economic, and ecological factors. While social factors (kinship, education) show the same relevance at each step of migration, ecological factors such as the occurrence of dzud seem more relevant at the early stages, from the steppe to the sum centres. Ecological factors only seem to rank second in importance, after social reasons. Economic reasons are also revealed to be very significant but seem most relevant the closer the migrations are to the capital. These results are essential in order to cope with current and future challenges of population development and find solutions to enable traditional Mongolian nomadism even under a modern lifestyle.

First, we try to shift the perspective from humans towards wildlife and regard modern era (near) extinctions of selected wildlife species as an ultimate expression of HWC. We then reflect on the legitimacy of ecosystem comparisons beyond the borders of biogeographical regions—an important prerequisite for global approaches. In the following, we present two case scenarios that exemplarily illustrate the topic from different perspectives: carnivore–livestock conflicts (classical view, human perspective) and wind turbine-induced mortality of bats (wildlife perspective, rarely regarded as a form of HWC). On this basis, we try to develop a framework that enables a global approach, while adequately considering case- and region-specificity. We think that a globally valid and generally approachable dimension can be defined, as long as there is a natural link: in the present case the established monophyly of the orders Carnivora and Chiroptera, i.e., representatives descending from common ancestors, thus sharing common ecological features. This natural relationship among all representatives of a systematic group (specification of the “wildlife” concept) is key for the development of an overarching strategy that can be adjusted to a specific case.

We investigated and compared the acoustic behavior of free ranging bats in rural (Havelland, Brandenburg) and urban (Berlin city center) green areas (n = 6 sites) to assess possible effects of urbanization on bat vocalizations using automated real-time recordings from May to October 2020 and 2021. We show that foraging and social call activity of commonly occurring bat species was lower in urban areas compared to rural areas. We present data on rural-urban variation in acoustic parameters of echolocation and Type D social calls (produced during flight) using the example of the common pipistrelle Pipistrellus pipistrellus. Calls from urban sites revealed significantly higher end and peak frequencies compared to rural site calls. In addition, urban social calls present a higher degree of complexity as they structurally differed from rural social calls with regard to assemblage and number of call components. Moreover, urban social calls were emitted in a presumably different context than rural calls: antagonistic social calls in urban areas were detected throughout the year and in the acoustic absence of conspecifics and heterospecifics. Our results provide evidence for the ability of P. pipistrellus to modulate temporal and spectral features of echolocation and social calls, as well as patterns of social call production, in order to compensate for constraints imposed by the urban acoustic environment. We suggest that this acoustic behavioral plasticity plays a major role in the degree of adaptation of insectivorous bats to urban habitats.

Student tutors change into the role of teachers and organize lectures, excursions, and assignments at the Real-World Laboratory “Ackerbaum”—an agroforestry system in the federal state of Brandenburg, Germany. Students can learn about agroforestry systems, participate in research, and take practical action. The examination of the module is a scientific report linked to the experimental area. In this study, an attempt was made to verify the quality and impact of teaching formats in the ITL via the analysis of 53 reports created by 170 students as well as surveys among participants. For this purpose, indicators were formulated that capture the quality of scientific methods and the contribution to higher education for sustainable development. Students and tutors appreciate the open working atmosphere and the possibility to actively participate in the course; many leave the module motivated. Some even move toward transformation in agriculture professionally as, e.g., consultants in the field of agroforestry. As a transformative institution, HNEE offers with ITL a rare opportunity for practical application, scientific methods, and transdisciplinary collaboration with different stakeholders to work on future models to change today’s agriculture.

In Central Asia, tree windbreaks from mainly poplar trees have a long tradition, but were largely cut down as source for fuel wood after the disintegration of the Soviet Union. As Central Asia is a forest-poor region, restoration of tree windbreaks has the potential to provide timber and wood resources to that region. This study aimed to assess the potential of tree windbreaks to contribute to domestic timber and wood production. Methods: This study rests on a GIS-based analysis, in which tree lines (simulated by line shape files) were intersected with cropland area. The tree data to calculate timber and wood volumes stem from a dataset with 728 single trees from a relevant range of climatic conditions. Results: The potential annually available timber volumes from tree windbreaks with 500 m spacing are 2.9 million m3 for Central Asia as a whole and 1.5 million m3 for Uzbekistan alone, which is 5 times the current domestic roundwood production and imports of the country. Conclusions: tree windbreaks offer untapped potential to deliver wood resources domestically as a raw material for wood-based value chains.

Perspectives for Anchoring Sustainability in Higher Education Curricula JF - Sustainabilty N2 - The study investigates the extent to which sustainability is anchored in university curricula of a federal state (Brandenburg, Germany). (1) It provides a baseline for identifying opportunities for sustainability-related curriculum reform by analyzing study programs, levels and type of degree, level of anchoring, and context within the documents. (2) The case studies included an analysis and quantitative evaluation of 748 curricular documents. (3) A third of the study programs refer to sustainability; to an equal extent in both bachelor’s and master’s programs, and to an above-average extent in the fields of science and engineering. There is a strong commitment to sustainability in 12% of the curricula; however, it is strongly anchored in only 3% of study and examination regulations, and in only 9% of module descriptions. (4) For the first time, we have comprehensive results on sustainability in university curricula of an entire federal state and can discuss potentials for its further integration. The innovative method was developed out of the National Monitoring on Education for Sustainable Development (ESD) and adapted to the federal state level; the analysis of curricula through a wider set of variables is transferrable to other states.

The large forests dominated by Scots pine (Pinus sylvestris L.) that cover the lowland regions in northeast Germany have already been affected regularly by cyclic mass propagations of defoliating insect species in the past with climate projections implying an even more advantageous environment for devastating outbreaks in the future. To improve predictive and responsive capacities we have investigated a wide range of ecological parameters to identify those most strongly related to past outbreak waves of three central species. In total, we analyzed 3,748 variables covering stand and neighborhood properties, site quality, and climatic conditions for an area of roughly 750,000 ha of pine forests in the period 2002–2016. To reflect sensitivity against varying climate, we computed “floating windows” in relation to critical phenological phases of the respective insects. The parameters with the highest explanatory power resulted from the variable importance measures of the Random Forest (RF) methodology and have been evaluated by a 10-fold cross-validation process. Our findings closely reflect the known specific gradation patterns and show that relative variable importance varies with species. While Lymantria monacha L. feeding was mainly dependent on the surroundings of the respective stand, Diprion pini L. proved to be almost exclusively susceptible to climatic effects in its population dynamics. Dendrolimus pini L. exhibited a mixed pattern of variable importance involving both climatic and forest structure parameters. In many cases the obtained statistical results support well-known ecological cause-effect relations and long-term population change dynamics. The RF delivered very high levels of sensitivity and specificity in the developed classifications and proved to be an excellent tool to handle the large amounts of data utilized for this study. While the presented classification approach may already support a better prognosis of the amplitude during the outbreak culmination, the obtained (most important) variables are proposed as preferable covariates for modeling population dynamics of the investigated insect species.

These data were combined with soil pH value and apparent electrical conductivity (ECa) from on-the-go proximal sensing serving as indicators for soil-borne causes of grassland biomass variation. The field internal magnitude of spatial variability and hidden correlations between the variables of investigation were analyzed by means of geostatistics and boundary-line analysis to elucidate the influence of soil pH and ECa on the spatial distribution of biomass. Biomass and pH showed high spatial variability, which necessitates high resolution data acquisition of soil and plant properties. Moreover, boundary-line analysis showed grassland biomass maxima at pH values between 5.3 and 7.2 and ECa values between 3.5 and 17.5 mS m−1. After calibrating ECa to soil moisture, the ECa optimum was translated to a range of optimum soil moisture from 7% to 13%. This matches well with to the plant-available water content of the predominantly sandy soil as derived from its water retention curve. These results can be used in site-specific management decisions to improve grassland biomass productivity in low-yield regions of the field due to soil acidity or texture-related water scarcity.

Tree height has traditionally been measured by indirect field-based techniques, however these methods are rarely contested. With recent advances in Unmanned Aerial Vehicle (UAV) remote sensing technologies, the possibility to acquire accurate tree heights semi-automatically has become a reality. In this study, photogrammetric and field-based tree height measurements of a Scots Pine stand were validated using destructive methods. The intensive forest monitoring site implemented for the study was configured with permanent ground control points (GCPs) measured with a Total Station (TS). Field-based tree height measurements resulted in a similar level of error to that of the photogrammetric measurements, with root mean square error (RMSE) values of 0.304 m (1.82%) and 0.34 m (2.07%), respectively (n = 34). A conflicting bias was, however, discovered where field measurements tended to overestimate tree heights and photogrammetric measurements were underestimated. The photogrammetric tree height measurements of all trees (n = 285) were validated against the field-based measurements and resulted in a RMSE of 0.479 m (2.78%). Additionally, two separate photogrammetric tree height datasets were compared (n = 251), and a very low amount of error was observed with a RMSE of 0.138 m (0.79%), suggesting a high potential for repeatability. This study shows that UAV photogrammetric tree height measurements are a viable option for intensive forest monitoring plots and that the possibility to acquire within-season tree growth measurements merits further study. Additionally, it was shown that negative and positive biases evident in field-based and UAV-based photogrammetric tree height measurements could potentially lead to misinterpretation of results when field-based measurements are used as validation.

While the literature reveals the essential role that community gardens can play in terms of learning and education, no studies have investigated the training needs for participants in community gardens to ensure their successful development. The goal of this article is to evaluate the training requirements of urban community gardens to ensure their successful implementation and their contribution to sustainability in European cities. Two questionnaires of users’ needs analysis were designed and implemented in Berlin, Bologna, Budapest, and Cartagena. The results unveiled the need to re-enforce the training in the formation and community building phases of community gardens towards ensuring the creation of an engaged gardening community to maintain activity, particularly for top-down activities (e.g., research-related gardens). Users claimed their need for being trained on crop management skills (e.g., maintenance, bed preparation, organic practices) and on communication skills to further disseminate their activity, thereby increasing the potential for citizen engagement. Such requirements could be overcome with the creation of urban gardens networks, where experiences and knowledge are shared among practitioners. Policy recommendations are provided based on the outputs of this study.

Within the CEN member states (European Committee for Standardization), the so-called Eurocodes form the basis of the design and verification of the load-bearing capacity of structures. Current Eurocodes do not contain special recommendations for existing structures, meaning that the principles for new structures are applied. This can lead to an incorrect estimation of the load-bearing capacity within the semi-probabilistic safety concept. A central task within the investigation and evaluation of existing structures is the strength grading of the material in situ using non-/semi-destructive technical devices. Studies show the potential of the ultrasonic time-of-flight measurement in combination with visual evaluation for an improved grading. The information on the material from an improved grading technique can be used to update the material parameters as a target variable using a measured reference variable. In this contribution, test data from a partner project (spruce, pine, and oak) are analyzed, applying the stochastic grading model of Pöhlmann and Rackwitz. It can be shown that different grading techniques influence the updated distribution function of the material strength within the grade. The results depend on the timber species. Perspectives to develop updated models dependent on the knowledge available are shown and discussed.

Between 1976 and the early 2000s, most LH species were absent in this area following the civil war in Mozambique followed by intense poaching due to weak law enforcement capacity. Through the reconstruction of the historical and current distribution and movement patterns of seven LH species in five periods, we investigate possible changes in distribution and movement patterns over time. Data collection is based on a systematic literature search, censuses reports, online databases, dung count transects, and camera trap surveys. We mapped all LH observations and movements using ArcGIS 10.1. Our results reveal a dramatic collapse of LH populations between the peak of the colonial period and the post-colonial/civil war period (1800–2001), followed by a slight recovery from the post-proclamation of Great Limpopo Transfrontier Park to the current period (2002–2021). While LH population decline applied to all seven species, there are species-specific differences in the process of restoration: African elephant (Loxodonta africana), African buffalo (Syncerus caffer), and plains zebra (Equus quagga) appear to recover to a greater extent than giraffe (Giraffa camelopardalis), eland (Tragelaphus oryx), blue wildebeest (Connochaetes taurinus), and white rhino (Ceratotherium simum). We found evidence of the functioning of proposed wildlife corridors in the LNP. The results give reason to assume that restoration of populations of LH is still in a very early and vulnerable state and that further efforts are necessary to strengthen the slowly increasing populations of LH. Our results highlight the importance of combining past and current data as a guide for the restoration of threatened species in African savannas impacted by human activities.

ER - TY - JOUR A1 - Braun, Charis Linda A1 - Bitsch, Vera A1 - Häring, Anna Maria T1 - Developing agri-food value chains: learning networks between exploration and exploitation JF - The Journal of Agricultural Education and Extension N2 - Purpose The present study explores the development of agri-food value chains from an organizational learning perspective, using the German organic food sector as an example. We illustrate how the development of local value chains unfolds over time and outline how facilitation can support this process. Design/methodology/approach The study used an action research design to facilitate change in practice and to create new knowledge. Data were collected through qualitative interviews, participant observation, and documentation of workshops and other learning activities. Data analysis and conceptualization followed a grounded theory approach. Findings The development process of value chains occurs in three phases, from joint exploration of the problem, through a phase of experimentation and implementation, to further cultivation of established collaborations among value chain actors. The development process oscillates between intra- and inter-organizational learning as well as explorative and exploitative activities. Practical implications The results of this study can help to understand and to further professionalize the practice of value chain development and provide guidance for facilitators and other stakeholder working in this field. Theoretical implications By drawing on the theory of exploration and exploitation, the study enhances the understanding of value chains collaboration in an inter-organizational setting. The study conceptualizes the development of agri-food value chains and the role of facilitators in the process. Originality/value There is little research to date that considers the development of value chains as a collaborative learning process. The presented grounded theory of local value chain development may inform further research on the transition towards a more sustainable agri-food system.

A1 - Will, Andreas T1 - Rigor and Relevance : Enforcing dialogue between media management research and practice T2 - Diskussionspapiere Menschen, Märkte, Medien, Management N2 - There is a strong demand in media management to strengthen the bridge between theory and practice. Following the debate on rigor and relevance, the approach of engaged scholarship and arguments from our community, we see the need to develop a research agenda in dialogue with practice. Therefore, we explore the following questions: Which topics do media managers consider relevant to research? How can these issues be contrasted with the research agendas proclaimed by media management research? To answer these questions, we first summarize current issues in media management research through a literature review. Second, current issues in media management practice are captured based on an online survey with German media managers (N=46). Finally, the two perspectives are contrasted to develop relevant questions for media management research and practice.

The aim was to identify the plasticizing effects of moisture on phenol-formaldehyde-impregnated veneers. Thin beech veneer samples were impregnated with a low and a medium molecular weight phenol- formaldehyde resin. The measurements were performed with a dynamic- mechanical thermal analysis equipped with a humidity generator. The storage modulus and the loss factor of the uncured phenol-formaldehyde- impregnated and the untreated control veneers were determined at a relative humidity of 15%, 60%, and 85% and a constant temperature of 25 °C. The untreated control veneers exhibited the smallest reduction of the normalized storage modulus. In contrast, the phenol-formaldehyde- impregnated samples exhibited a more intense relative reduction of the storage modulus with increasing relative humidity. This effect was more distinct for samples impregnated with low molecular weight phenol- formaldehyde than for those impregnated with medium molecular weight phenol-formaldehyde. In addition, higher solids contents in the resins led to even smaller normalized storage modulus. Consistently, the loss factor indicated a greater softening of the samples with an increasing humidity and higher solids content of the phenol-formaldehyde.
