What does this mean for sustainability research? Because of the scope of the crisis, researchers have been heavily involved: not only have they had to speed up the pace of scientific production to provide urgently needed COVID-19 knowledge, but they have also been affected citizens. For sustainability science, this calls for an experience-based reflection on the positionality and orientation of research aiming to support sustainability transformations. Twenty sustainability researchers discussed their sustainability research on COVID-19 in three workshops based on the following questions: How does the pandemic—and the measures taken to deal with it—affect sustainable development? What can we learn from the pandemic from the perspective of societal transformation? The present discussion paper emerged from this multidisciplinary exchange among sustainability researchers, considering five topics: impacts of the COVID-19 crisis on sustainability transformations; learning for sustainability transformations; the role of solidarity; governance and political steering; and the role of science in society. Our discussions led to a meta-level reflection on what sustainability research can learn from research on COVID-19 regarding topics and disciplinary angles, time dimensions, the role of researchers, and how adequate preparation for both crises and long-term transformations requires interdisciplinary interaction.}, language = {en} } @article{JochheimLuettschwagerRiek2022, author = {Jochheim, Hubert and L{\"u}ttschwager, Dietmar and Riek, Winfried}, title = {Stem distance as an explanatory variable for the spatial distribution and chemical conditions of stand precipitation and soil solution under beech (Fagus sylvatica L.) trees}, series = {Journal of Hydrology}, journal = {Journal of Hydrology}, number = {608}, publisher = {Elsevier}, issn = {0022-1694}, doi = {10.1016/j.jhydrol.2022.127629}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:eb1-opus-5306}, year = {2022}, abstract = {The partitioning of bulk precipitation (PR) in forest ecosystems and its chemical composition depends on both meteorological factors, such as precipitation amount and intensity, evaporation rate, and wind speed, and stand structural factors, such as stand density, canopy structure, bark texture, and spatiotemporal distribution and density of foliage. We analysed fluxes of water and element contained therein of a mature European beech (Fagus sylvatica L.) forest stand on sandy soils in northeastern Germany. We applied a radially symmetrical setup within a stem distance gradient to measure stand precipitation (SP) with its components of throughfall (TF) and stemflow (SF), as well as to measure soil moisture, the chemical composition of the soil solution, the soil chemistry, and the fine root distribution. The chemical analysis of the constituents covered the macroelements (Ca, Mg, K, Na, Al, Fe, Mn, Si, S, P), the cations and anions NH4+, NO3-, Cl-, SO42-, and a few heavy metals (Cu, Pb, Zn). With an average PR of 620 mm a-1, the partitioning resulted in 79\% TF, 6\% SF, and 15\% canopy interception. TF volume increased with distance to stem during summer, but decreased during winter. Clear spatial gradients with increasing concentrations from PR, to different classes of TF as the distance from the trunk decreased, to SF were observed for nearly all elements. The contact of precipitation with leaves and the canopy structures alters the chemical composition of TF and SF by transferring elements from dry deposition or leaching of intracellular materials from the canopy and leads to the input of larger amounts of macroelements and heavy metals with the SP into the soil. Spatial patterns of canopy structures thus affect the spatial variation of TF and its constituents, which also affects the spatial distribution of roots and, at least in phases, the chemical composition of the topsoil solution.}, language = {en} } @article{WinklerSchwarzSenge2020, author = {Winkler, Christoph and Schwarz, Ulrich and Senge, Bernhard}, title = {Materialwissenschaftliche Analyse des Abbindeverhaltens von Holzklebstoffen am Beispiel von 1K-PUR}, series = {Chemie Ingenieur Technik}, volume = {92}, journal = {Chemie Ingenieur Technik}, number = {6}, publisher = {Wiley}, issn = {0009-286X}, doi = {10.1002/cite.201900171}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:eb1-opus-5323}, pages = {759 -- 768}, year = {2020}, abstract = {Das Abbinden von Holzklebstoffen wird bisher anhand von Parametern bewertet, die kaum eine prozesstechnische Optimierung erm{\"o}glichen.

Still challenging is the model performance when considering complex interrelations between soil and crop dynamics under a changing climate. The objective of this study was to test the agronomic crop and environmental flux-related performance of a set of crop models. The aim was to predict weighing lysimeter-based crop (i.e., agronomic) and water-related flux or state data (i.e., environmental) obtained for the same soil monoliths that were taken from their original environment and translocated to regions with different climatic conditions, after model calibration at the original site. Eleven models were deployed in the study. The lysimeter data (2014-2018) were from the Dedelow (Dd), Bad Lauchst{\"a}dt (BL), and Selhausen (Se) sites of the TERENO (TERrestrial ENvironmental Observatories) SOILCan network. Soil monoliths from Dd were transferred to the drier and warmer BL site and the wetter and warmer Se site, which allowed a comparison of similar soil and crop under varying climatic conditions. The model parameters were calibrated using an identical set of crop- and soil-related data from Dd. Environmental fluxes and crop growth of Dd soil were predicted for conditions at BL and Se sites using the calibrated models. The comparison of predicted and measured data of Dd lysimeters at BL and Se revealed differences among models. At site BL, the crop models predicted agronomic and environmental components similarly well. Model performance values indicate that the environmental components at site Se were better predicted than agronomic ones. The multi-model mean was for most observations the better predictor compared with those of individual models. For Se site conditions, crop models failed to predict site-specific crop development indicating that climatic conditions (i.e., heat stress) were outside the range of variation in the data sets considered for model calibration. For improving predictive ability of crop models (i.e., productivity and fluxes), more attention should be paid to soil-related data (i.e., water fluxes and system states) when simulating soil-crop-climate interrelations in changing climatic conditions.}, language = {en} } @incollection{WelpYiliminuer2021, author = {Welp, Martin and Yiliminuer,}, title = {Stakeholder management}, series = {Sustainable Management of River Oases along the Tarim River/China (SuMaRiO)}, booktitle = {Sustainable Management of River Oases along the Tarim River/China (SuMaRiO)}, editor = {Cyffka, Bernd and Disse, Markus and Betz, Florian}, publisher = {Schweizerbart}, isbn = {978-3-510-65432-1}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:eb1-opus-5407}, publisher = {Hochschule f{\"u}r nachhaltige Entwicklung Eberswalde}, pages = {27 -- 32}, year = {2021}, language = {en} } @misc{KosteraStrauss2022, author = {Kostera, Monika and Strauß, Anke}, title = {Teaching what is not there}, series = {Culture and Organization}, volume = {28}, journal = {Culture and Organization}, number = {3-4}, publisher = {Taylor \& Francis}, doi = {10.1080/14759551.2022.2036922}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:eb1-opus-5716}, pages = {185 -- 193}, year = {2022}, language = {en} } @article{EdalatTholeFaezipour2021, author = {Edalat, Hamidreza and Thole, Volker and Faezipour, Mehdi}, title = {Experimental study on correlation between adhesive penetration pattern and mechanical performances in oriented strand board}, series = {European Journal of Wood and Wood Products}, volume = {79}, journal = {European Journal of Wood and Wood Products}, publisher = {Springer Nature}, issn = {0018-3768}, doi = {10.1007/s00107-020-01590-1}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:eb1-opus-5721}, pages = {59 -- 74}, year = {2021}, abstract = {The aim of the experimental study presented here is to investigate the correlation between adhesive penetration and mechanical performances of wood-based composites. For this purpose, oriented strand boards were made with poplar uni-strands and PF resin. To make differences in resin penetration, strand moisture content (MC) and resin solid content (SC) were selected as variables of the experiment. The adhesive penetration pattern was studied by the elemental counting method (ECM) in two layers of the boards' thickness. Mechanical properties including MOE, MOR, IB, tensile strength parallel to the grain, impact resistance, and creep bending were evaluated as well as resin droplets distribution. The results showed that strand MC and resin SC influence the mechanical performance and resin penetration parameters. The penetration parameters increased in the middle layer where the bondlines are close to heat and hydrodynamic pressure sources. The composites made with higher concentration resin and drier strands expressed weak penetration causing a reduction in mechanical properties except for tensile strength where the shear stress took place between bonded strands. Resin droplet size analysis proved that resin SC could change the droplet size distribution and influence the strengths. Strand MC could act as a modifying factor to develop the penetration and balance it between the layers.

However, so far only a limited number of species combinations have been studied in detail, revealing inconsistent results. In this study, we analysed the effect of mixing Scots pine and oak (pedunculate oak and sessile oak) trees on their drought response along a comprehensive ecological gradient across Europe. The objective was to improve our knowledge of general drought response patterns of two fundamental European tree species in mixed versus monospecific stands. We focused on three null hypotheses: () tree drought response does not differ between Scots pine and oak, () tree drought response of Scots pine and oak is not affected by stand composition (mixture versus monoculture) and () tree drought response of Scots pine and oak in mixtures and monocultures is not modified by tree size or site conditions. To test the hypotheses, we analysed increment cores of Scots pine and oak, sampled in mixed and monospecific stands, covering a wide range of site conditions. We investigated resistance (the ability to maintain growth levels during drought), recovery (the ability to restore a level of growth after drought) and resilience (the capacity to recover to pre-drought growth levels), involving site-specific drought events that occurred between 1976 and 2015. In monocultures, oak showed a higher resistance and resilience than Scots pine, while recovery was lower. Scots pine in mixed stands exhibited a higher resistance, but also a lower recovery compared with Scots pine in monocultures. Mixing increased the resistance and resilience of oak. Ecological factors such as tree size, site water supply and site fertility were found to have significant effects on the drought response. In the case of Scots pine, resistance was increased by tree size, while recovery was lowered. Resistance of oak increased with site water supply. The observed mixing effect on the tree drought response of Scots pine and oak was in some cases modified by the site conditions studied. Positive mixing effects in terms of resistance and resilience of oak increased with site water supply, while the opposite was found regarding recovery. In contrast, site fertility lessened the positive mixing effect on the resistance of Scots pine. We hypothesise that the observed positive mixing effects under drought mainly result from water- and/or light-related species interactions that improve resource availability and uptake according to temporal and spatial variations in environmental conditions.}, language = {en} } @article{delRioPretzschRuizPeinadoetal.2022, author = {del R{\´i}o, Miren and Pretzsch, Hans and Ruiz-Peinado, Ricardo and Jactel, Herv{\´e} and Coll, Llu{\´i}s and L{\"o}f, Magnus and Aldea, Jorge and Ammer, Christian and Avdagić, Admir and Barbeito, Ignacio and Bielak, Kamil and Bravo, Felipe and Brazaitis, Gediminas and Cern{\´y}, Jakub and Collet, Catherine and Cond{\´e}s, Sonia and Dr{\"o}ssler, Lars and Fabrika, Marek and Heym, Michael and Holm, Stig-Olof and Hylen, Gro and Jansons, Aris and Kurylyak, Viktor and Lombardi, Fabio and Matović, Bratislav and Metslaid, Marek and Motta, Renzo and Nord-Larsen, Thomas and Nothdurft, Arne and den Ouden, Jan and Pach, Maciej and Pardos, Marta and Poeydebat, Charlotte and Ponette, Quentin and P{\´e}rot, Tomas and Reventlow, Ditlev Otto Juel and Sitko, Roman and Sramek, Vit and Steckel, Mathias and Svoboda, Miroslav and Verheyen, Kris and Vospernik, Sonja and Wolff, Barbara and Zlatanov, Tzvetan and Bravo-Oviedo, Andr{\´e}s}, title = {Emerging stability of forest productivity by mixing two species buffers temperature destabilizing effect}, series = {Journal of Applied Ecology}, volume = {59}, journal = {Journal of Applied Ecology}, number = {11}, publisher = {Wiley}, issn = {1365-2664}, doi = {10.1111/1365-2664.14267}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:eb1-opus-5778}, pages = {2730 -- 2741}, year = {2022}, language = {en} } @article{PaulKuhnSteinhoffKnoppetal.2020, author = {Paul, Carsten and Kuhn, Kristin and Steinhoff-Knopp, Bastian and Weißhuhn, Peter and Helming, Katharina}, title = {Towards a standardization of soil-related ecosystem service assessments}, series = {European Journal of Soil Science}, volume = {72}, journal = {European Journal of Soil Science}, number = {4}, publisher = {Wiley}, issn = {1365-2389}, doi = {10.1111/ejss.13022}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:eb1-opus-5801}, pages = {1543 -- 1558}, year = {2020}, abstract = {The concept of ecosystem services (ES) creates understanding of the value of ecosystems for human well-being.

The Common International Classification of Ecosystem Services (CICES) is an important step forward, although its application to soils is not without difficulty. CICES version 5.1 defines 83 ES classes, of which only some are relevant for soils. We compiled two subsets of CICES classes: one set of soil-related ES comprising 29 services defined as directly and quantifiably controlled by soils and their properties, processes and functions, and another set of 40 ES defined as being affected by agricultural soil management. Additionally, we conducted a systematic literature review, searching for published lists of soil-related ES that claim completeness. We identified 11 relevant lists. Of all CICES classes, 12 were included in more than 75\% of the lists, whereas another 36 classes were included in 25-75\% of them. Regarding the suitability of the CICES classification for addressing ES in the context of soils and their agricultural management, we identified constraints, such as overlaps, gaps, and highly specific or very broad class definitions. Close cooperation between the soil research and ES communities could ensure better consideration of soils in future CICES updates.

The spatial distribution of the WUE exhibited significant increases in the northern part of KAZ, the Ili Valley and the alpine region in KGZ and exhibited decreases in south Xinjiang and the irrigated area of UZB. (2) The main land cover types that exhibited changes in WUE were farmlands and grasslands, and areas with a medium population density exhibited large WUE changes. (3) The increased WUE resulted from an increased GPP and decreased ET. The increased GPP was because of increased precipitation and the Green for Grain Project, and the decreased ET was due to the response of vegetation to drought stress; the decreased WUE was mainly caused by changes in the crops planted and unreasonable water use practices in the irrigated agricultural areas in Central Asia.

However, the complex interactive coercing relationship between urbanization and ES is not yet fully understood, especially in arid Northwestern China. In this study, we constructed an evaluative framework for urbanization and ES using land cover/land use data and socioeconomic data from 1990 to 2018. We used global and local autocorrelation models to reveal the spatiotemporal interaction between urbanization and ES. The results revealed that the urbanization index increased from 0.06 in 1990 to 0.16 in 2018 in Xinjiang, and urbanization was significantly negatively correlated with ES. With the acceleration of urbanization, the ecosystem services value (ESV) has decreased 2,698.74 × 109 Yuan from 1990 to 2018 (6.62 Yuan = 1 .00 US\$). Due to geographical advantages, resource conditions, and land use changes, the spatial relationship of urbanization and ES has obvious heterogeneity. High-low correlation areas are mainly concentrated in the Northern Tianshan Mountain Economic Zone, whereas low-high correlation areas are concentrated in the Kashgar and Hotan Oases in southern Xinjiang. Based on regional geographical conditions and the spatial heterogeneity of resources, diversified ecological, social, and economic balance models should be considered to promote future sustainable urban planning and development.}, language = {en} } @article{ShiHalikMamatetal.2021, author = {Shi, Lei and Halik, {\"U}m{\"u}t and Mamat, Zulpiya and Aishan, Tayierjiang and Welp, Martin}, title = {Identifying mismatches of ecosystem services supply and demand under semi-arid conditions: The case of the Oasis City Urumqi, China}, series = {Integrated Environmental Assessment and Management}, volume = {17}, journal = {Integrated Environmental Assessment and Management}, number = {6}, publisher = {Wiley}, issn = {1551-3777}, doi = {10.1002/ieam.4471}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:eb1-opus-5469}, pages = {1293 -- 1304}, year = {2021}, abstract = {Understanding the balance between supply and demand of ecosystem services (ESs) is helpful for sustainable urban management. However, the interactions among multiple ESs supplies and demands remain under-researched, and ESs supply and demand spatial heterogeneity and correlation characteristics at the city level are rarely studied, especially in arid areas. To fill this gap, we established a comprehensive assessment framework of ESs supply and demand through integrating multi-source remote sensing data, social economy, and policy objectives, for the oasis city of Urumqi, China. The ESs supply-demand mismatches were revealed at the city level, and the spatial relationship between the ESs supply and demand was analyzed using spatial statistics. The results demonstrated that: (1) The total quantity of supply and demand of food provision, carbon sequestration, PM10 removal, and recreation services in Urumqi revealed that the demand was greater than the supply, the deficits being 16.10 × 107 kcal/ha, 6.88 × 104 t/ha, 155.86 kg/ha, and 697.26, respectively. (2) The supply and demand assessment of ESs revealed spatial differences from the city center to the suburbs, which further indicated that there are neighborhood similarities between the supply and demand of ESs. (3) The matching types of ESs supply and demand present obvious spatial heterogeneity, which can be divided into four types: High-high, high-low, low-high, and low-low. Owing to rapid urban development in the inner city, the city center is dominated by low-high, whereas the urban-rural ecotone is characterized by high-low, owing to the higher elevation and water resource advantages in the suburbs. Based on the analysis of the supply, demand, and matching of ESs, economic development and sustainable management policies are proposed for different ecological spaces.
