TY - JOUR A1 - Brandt, Jan-Ole A1 - Barth, Matthias A1 - Hale, Annie A1 - Merritt, Eileen T1 - Developing ESD-specific professional action competence for teachers: knowledge, skills, and attitudes in implementing ESD at the school level JF - Environmental Education Research N2 - Equipping future change agents with the competencies to lead the societal transformation towards sustainability requires competent and committed teachers who effectively implement Education for Sustainable Development (ESD) across the education system. In a comparative case study, this paper investigates how individual ESD courses in teacher education programs at Leuphana University (Germany) and Arizona State University (USA) support the development of ESD-specific professional action competence for teachers. Applying a mixed-method approach, the specific focus is on the links between supporting or hindering factors that affect pre-service teachers’ actual achievement of intended learning outcomes. The findings indicate that both courses increased students’ competence—yet, to varying degrees. The 4Cs (personal, professional, social, and structural connections) were revealed as the most significant factors affecting students’ learning and should be considered when designing course offerings in Teacher Education for Sustainable Development (TESD) with the goal to develop students’ knowledge, skills, and attitudes.

T1 - Ein ökosystembasierter Ansatz für den Umgang mit der Waldkrise in der Klimakrise JF - Natur und Landschaft N2 - Die vorherrschenden Strömungen in Diskurs und Praxis forstlicher Klimawandelanpassungen stehen einem ökosystembasierten Ansatz entgegen. Es wird auf Baumarten fokussiert; aktive Anpassung bedeutet oftmals das Anpflanzen ökosystemfremder Arten. Die Bemühungen, zukünftige Waldtypen möglichst artenscharf zu definieren, offenbaren ein deterministisches Gestaltungsparadigma. Dieses kann darauf zurückgeführt werden, dass die bioenergetisch bzw. thermodynamisch untermauerte Nichtgleichgewichtsökologie nicht rezipiert wurde. Auf der Grundlage aktueller systemökologischer Theorien und Befunde wird in zehn Prinzipien ein Ansatz ökosystembasierten Waldmanagements skizziert. Ökosystemfunktionalität kann thermodynamisch beschrieben und quantifiziert werden; im Mittelpunkt steht die Energiedissipation(sfähigkeit). Ökosystembiomasse und -informationsgehalt sowie ein kohärentes holarchisches Netzwerk sind die Grundlage für die physikalische Arbeitsfähigkeit, aber auch für Resistenz und Resilienz. Aus den thermodynamischen Eigenschaften und der Komplexität ergeben sich ontische Offenheit und Unbestimmtheit von Waldökosystemen. Ein ökosystembasiertes Waldmanagement fokussiert auf Strukturen und Prozesse, die Kühlung und Wasserrückhaltung sowie Selbstregulation im System vermitteln.

T1 - Participatory learning for transdisciplinary science in biosphere reserves T2 - UNESCO Biosphere Reserves N2 - Biosphere reserves (BRs) are model regions for testing participatory approaches to establish a new relationship between human beings and nature. This requires changes in land use and in biodiversity and natural resource management. Driving changes of this kind is challenging. BRs, therefore, need knowledge about how to organize participatory processes, prevent conflict and encourage cooperation among multiple stakeholders including municipalities, land users and scientists. Learning, education, experimentation and participation across different cultural contexts play a major role in biosphere reserves. BRs are or should be Science for Sustainability support sites – special places for testing interdisciplinary approaches to understanding and managing changes and interactions between social and ecological systems, including conflict prevention and management of biodiversity. Universities can participate in this learning process by contributing theoretical and empirical knowledge. Moreover, as universities maintain academic neutrality when it comes to the conflicts of interests among stakeholders in BRs, they can play the role of catalyst by initiating and reflecting on processes. With this role for universities, BRs would not only become places for research, but also places for participation and learning for sustainability. In this article, we outline this modified role with three examples of transformative research and teaching between German biosphere reserves and the Eberswalde University for Sustainable Development.

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. The results of the correlation analysis proved a significant relationship between mechanical properties and penetration parameters, in particular, those obtained from fiber quantity.

Three experiments have focused on different aspects of the production of electrically conductive adhesive wood bonds, experiment I with a variation of the adhesive components, experiment II is varying the process parameters in the bonding process, and experiment III is investigating a thermal postcuring effect. Tensile shear strength (EN 302–1, requirement for structural wood bonding dry condition (A1 treatment)) and electrical resistography under direct current (DC measurements) of the bondline was used to identify major influences on tensile shear strength and the formation of the electrically conductive network. The results show high differences due to the adhesive polymer selection, the filler type and some of the process parameters. As an example, it was revealed that the bond strength of multifunctional adhesive wood joints can be increased by integrating increasing contents of carbon nanotubes in polyurethane prepolymers, if the polymers do not contain fibrous fillers before the dispersion.

Applied as sensor elements in engineered timber, these multifunctional adhesive bondlines are influenced by a lot of process parameters, including the dispersion process, manufacturing parameters and postcuring conditions. Additionally, the sensitivity of these sensor elements is counteracted by instabilities of the piezoresistivity. A setup and analysing method of the piezoresistive response have been developed, which includes sensitivity as well as instability effects. With this setup, the quality of the piezoresistive bondline has been assessed by three experiments, varying 10 influencing factors. The piezoresistive response was investigated in compression perpendicular to the bondline. It was shown that the electrical sensitivity in compression and stability of the piezoresistive bondline can be influenced by polymer formulation, filler type, filler content as well as the press temperature, glue spread, dispersion technique and thermal postcuring.

In this study, the Mann-Kendall (MK) test was used to study the variabilities in the spatial patterns of the gross primary production (GPP), evapotranspiration and WUE across Central Asia [the Xinjiang Uyghur Autonomous Region (XJ) in China (CHN), Kazakhstan (KAZ), Turkmenistan (TKM), Uzbekistan (UZB), Kyrgyzstan (KGZ), and Tajikistan (TJK)] from 2000 to 2014. We compared the change results by country, land cover type, population density, and human influence. In addition, the results of GPP, evapotranspiration (ET), and WUE parameter tests were combined and classified to analyse the causes of the changes in WUE. The results showed that (1) the time series of GPP, ET and WUE exhibited no significant changes. 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. This study, which is based on the variabilities in WUE spatial patterns, should provide a theoretical basis for ecosystems in arid land areas.

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.

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.

These lands fulfil a range of ecosystem services, goods, and functions. Increasing natural and anthropogenic pressures impose threats to these lands. This paper first describes the Quercus genus and discusses management and mismanagement practices of oak systems. Then, the provisioning ecosystem services related with oak systems are reviewed, including: (1) oak’s agroforestry and silvopasture systems for the production of food, pasture, and additional products; (2) browsing of oak leaves and acorns by livestock; (3) harvesting of oak wood for timber; (4) cork oak stripping, and the uses of cork; (5) acorn-based foods and beverages; and (6) others uses, such as the production of medicines and extraction of tannins for the leather industry. We discuss the multi-purpose and multi-functional nature of oak systems, and demonstrate how they diversify sources of income for local communities, resulting in improved economic and food security. Further, we show the important role of woodlands certification, aimed at protecting oak systems while ensuring environmental equity. Also, we demonstrate how providing of financial support for reforestation and afforestation schemes of degraded oak woodlands, could restore ecosystem functioning and reverse land degradation. Then, we stress the need to involve traditional knowledge in restoration schemes of degraded oak systems. Lastly, we demonstrate how policymaking and legislation regarding the oak’s commercial plantations and farming systems could alleviate stresses imposed on the world’s oak woodlands and forests by producing alternative sources of wood for the timber industry.

Euphrates poplar (Populus euphratica Oliv.) is the only constructive tree species of the desert riparian forests along the Tarim River in northwestern China. The ecosystem stability of these forests has been damaged due to widespread internal decay or hollow rot in many tree trunks. However, forest resource conservation is difficult due to the unclear spatial patterns of P. euphratica trunk decay under different water conditions and tree morphology in the middle (MTR) and lower reaches (LTR) of the Tarim River. We conducted a field experiment and lab analysis to assess the reliability of the ARBOTOM® 2D stress wave Non-Destructive Testing (NDT) technique on P. euphratica populations. We explored the quantitative characterization method and the spatial distribution patterns of P. euphratica trunk internal decay in the MTR and LTR. Our study found that (1) the accuracy of the stress wave NDT technique in detecting trunk decay of P. euphratica in the arid desert area was more than 80%; The severity of internal trunk decays can be quantitatively characterized by the combination of the Matlab Image Processing Toolbox, (2) the trunk decay proportion of P. euphratica showed an increasing trend with the tree height in the MTR. The LTR first increased, then decreased. The degree of decay was highest when the tree height was 6–7 m. The trunk decay proportion of individual trees positively correlated with the diameter at breast height and crown loss (p < 0.001) and negatively correlated with the crown diameter (p < 0.001). The higher the decay occurrence, the worse the individual size was, and vice versa, and (3) the decay proportion of the P. euphratica showed an overall increasing trend with an increase in groundwater depth. The trunk decay was significantly higher in the LTR compared to the MTR at the same distance of 300–1050 m from the river channel. Our findings suggested that the trunk decay in P. euphratica had a higher difference among different tree morphology, and the occurrence of decay in the LTR was much higher than in the MTR. The water stress at the site is one of the leading factors in internal defects in the riparian forests along the Tarim River. The results provide a theoretical basis and scientific support for desert riparian forest ecosystems’ conservation and sustainable management.

During the year, the company must monitor the stock for accountability reports and internal governance. This paper proposes a more efficient and precise survey method that overcomes the challenges of the common monitoring system in Brazil. In this study, a monitoring method based on digital stereoscopy from UAV images was implemented and evaluated. The results were compared with those of the traditional topographic survey based on RTK equipment. A multi-engine UAV, with an integrated global navigation satellite system (GNSS) and real-time kinematic positioning (RTK) equipment was used to fly over and survey a masonry oven complex containing eight charcoal heaps. Two stereoscopic processing methods were applied: (1) very low quality and (2) high quality to image alignment, reconstruction of a dense cloud, facet count and a three-dimensional mesh creation. Low-quality products showed geometric deformities when compared to high quality, but resulted in estimations similar to the topographic survey. Results indicated that the volume estimation of the charcoal heaps using UAV derived orthomosaics can replace the conventional method of GNSS RTK surveys with considerable gains in stockpile volume accuracy, inventory frequency and labour safety. The high quality processing method registered improvements in geometric precision and accuracy.
