It is widely accepted that environmental awareness is essential, yet does not inevitably lead to responsible use of resources. Additional factors on the individual level include the meaning constructed by the term "resources" and the individual and social norms that influence the relevant behavior. Current didactic concepts do not take into account such aspects. Therefore, this article uses a didactic-psychological approach for designing an educational concept for raising awareness for a responsible use of natural resources. Combining insights of environmental psychology and of constructivist didactics, a general principal of "norm-oriented interpretation learning" is outlined to enrich the didactic debate on responsible and efficient resource use. Based on the presentation of a qualifying module for resource efficiency consultants as a practical example of resource education, a new didactical approach, namely "open-didactic exploration" (short form: ODE) is introduced. The article discusses the theory-based elements of ODE and illustrates a step by step process for designing educational materials. This adds to the theoretical debate about a didactic design for resource oriented education. Furthermore, this method can be directly used by practitioners developing education and training material (e.g., teachers, trainers in vocational education). The Wuppertal Institute developed and applied this method in numerous projects. The conclusion and outlook discusses future expectations and scope of the introduced ODE method as a contribution to foster "norm-oriented interpretation learning", suggesting perspectives for further development.
"Selbst-Check Handwerk" : Selbstbewertung zum nachhaltigen Wirtschaften in Handwerksbetrieben
(2007)
The article estimates the natural resource consumption due to nutrition from the supply and demand sides. Using the MIPS (Material Input per Service Unit) methodology, we analyzed the use of natural resources along the supply chains of three Italian foodstuffs: wheat, rice and orange-based products. These figures were then applied for evaluating the sustainability of diets in 13 European countries. The results outline which phases in food production are more natural resource demanding than others. We also observed different levels of sustainability in the European diets and the effect of different foodstuffs in the materials, water and air consumption.
The European Commission has established the Eco Management and Auditing Scheme (EMAS) to promote and institutionalize corporate environmental management and environmental audits. This article summarizes a study primarily concerned with the execution of an ecoaudit in a medium-sized furniture enterprise according to the rules of EMAS. Material flow accounting was used to assess and analyze the "gate-to-gate" and "cradle-to-grave" environmental impacts related to the firm's products and activities. A resource management strategy was developed that permits the determination of methods for firm-specific material flow management, product management, and ecological product design to improve environmental performance as seen from the vantage point of resource efficiency.
Human nutrition is responsible for about 30% of the global natural resource use. In order to decrease resource use to a level in line with planetary boundaries, a resource use reduction in the nutrition sector by a factor 2 is suggested. A large untapped potential to increase resource efficiency and improve consumers' health status is assumed, but valid indicators and general guidelines to assess these impacts and limits can barely be found. Therefore we will have a try to define sustainable limits towards the individuals' daily diet and therefore stimulate current available scientific debate.
Within the paper an examination of existing indicators and assessment methods is carried out. We set the focus on health indicators, such as energy intake, and environmental indicators, such as the carbon or material footprint. The paper aims to provide first, an assessment of core indicators to explore the sustainability impact of foodstuff, and second, a deeper understanding and a discussion of sustainable limits for those dimensions of food and nutrition. Therefore we will discuss several ecological and health indicators which may be suitable to assess the sustainabilty impact and indicate differences or similarities. As a result it becomes obvious that several ecological indicators "point in the same direction" and therefore a discussion about the variability and the variety of these indicators has to be faced in the future. Further the definition of sustainable levels per indicator is an essential aspect to get an idea about the needed barriers for a sustainable nutrition, by now first steps had been made, but no binding guidelines are available yet. Therefore the paper suggests a few indications to set up sustainable levels for health and environmental indicators, based on the idea to reduce the resource use level up to 30-50% in 2030.
Assessing the natural resource use and the resource efficiency potential of the Desertec concept
(2013)
Considering global warming, increasing commodity prices, and the dramatic consequences of the over-exploitation and overuse of resources, a transition to a renewable energy supply is necessary. This requires an (resource) efficient and renewable supply of operating reserve. In this article, a possible solution to this problem is analysed: the Desertec concept. It is meant to convert solar energy in areas with high solar irradiation into electrical energy by means of Concentrated Solar Power (CSP) transferring this energy by High Voltage Direct Current (HVDC) lines into the whole European Union Middle East and North Africa (EU-MENA) area. In order to assess the resource efficiency potential of Desertec, three different kinds of CSP plants (parabolic trough, Fresnel collector and central receiver of the building classes Inditep, Novatec and Solar Tres) including heat storage systems (Molten Salt and Phase-Changing-Material) and the necessary HVDC are analysed using the Material Input per Service Unit (MIPS) methodology. The assessment is accomplished for three different locations (Morocco, Tunisia and Egypt) and two points of time (2025 and 2050). With these results, a scenario of electricity supply in Germany in 2050 with a 20% share of solar power import is calculated. Central receivers are the most resource efficient ones: their consumption of abiotic materials is only half of parabolic trough plants and two thirds of Fresnel trough plants. Water and air consumption is the lowest of all analyzed CSP plants as well. The scenario for Germany's fuel mix in 2050 shows that a predominantly renewable fuel mix reduces the consumption of abiotic materials by 75%, of water by 60% and of air by 45%. Only the consumption of biotic materials rises due to the higher share of biomass conversion.
Auf KURS in die Zukunft
(2006)
Eine nachhaltige Entwicklung zielt auf den Erhalt der Umwelt unter weltweit sozialverträglichen und wirtschaftlich verlässlichen Bedingungen. Für den nötigen gesellschaftlichen Kurswechsel werden technologische, soziale und organisatorische Innovationen benötigt, die im privaten Umfeld (Familie, Vereine) wie im beruflichen Kontext (Unternehmen, Bildungseinrichtungen) von jedem einzelnen vorangebracht werden können. Um Zukunft durch Innovationen gestalten zu können, müssen junge Menschen zusätzlich zu ihrer beruflichen Qualifikation als Bürger zu gesellschaftlicher Teilhabe befähigt und motiviert werden. Mit entscheidend hierbei ist ein erfolgreicher Übergang von der Schule in den Beruf. Die Kooperation zwischen Schule und Wirtschaft und die damit zusammenhängende Öffnung der beiden unterschiedlichen Systeme kann einen wichtigen Beitrag dazu leisten. Die Studie versucht, ausgehend von aktuellen bildungspolitischen Zielsetzungen und im Rahmen einer nachhaltigen Entwicklung, die Bedeutung der Kooperation von Schule und Wirtschaft herauszustellen sowie entsprechende Handlungsempfehlungen für deren Ausgestaltung und Weiterentwicklung zu geben.
