The relationship between large-scale metal mining and its impacts is a topic of growing discussions in Argentina. Multinational mining corporations publish sustainability reports in order to show their social responsibility and contributions to sustainable development. These reports promote a higher transparency but doubts remain as to its usefulness to improve relationships with communities. By using a descriptive-explanatory method, this study analyses the 2009 Sustainability Report of Bajo de la Alumbrera mine so as to assess its quality and compare the "reality" painted by the company with the views of conflict by critical stakeholders. Results, validated with reports from other years, show the need to improve the information reported for conflictive indicators and, along with local governments, to implement a significant change in the way of making decisions, especially by engaging critical stakeholders.
Zwischen Anpassungs- und Veränderungsdruck : Klimafolgenanpassung und nachhaltige Transformation
(2015)
Strategien der Klimafolgenanpassung und der nachhaltigen Entwicklung werden in Deutschland kaum aufeinander bezogen. Kurzfristige Maßnahmenplanungen zur Schadensbegrenzung dominieren das politische Handeln, Fragen nach Vorsorge- und Gerechtigkeitsaspekten kommen zu kurz. Die Entwicklung resilienter Entwicklungspfade stellt eine Herausforderung für die real existierende Problembewältigung dar. Für die Umsetzung einer nachhaltigen und resilienten Klimaanpassungsstrategie ist ein Mix aus institutionell basierten Regeln und teilhabeorientierten Realexperimenten zur Erprobung von Neuem naheliegend.

A reduction in working hours is being considered to tackle issues associated with ecological sustainability, social equity and enhanced life satisfaction - a so-called triple dividend. With respect to an environmental dividend, the authors analyse the time use rebound effects of reducing working time. They explore how an increase in leisure time triggers a rearrangement of time and expenditure budgets, and thus the use of resources in private households. Does it hold true that time-intensive activities replace resource-intensive consumption when people have more discretionary time at their disposal? This study on environmental issues is complemented by introducing the parameters of voluntary social engagement and individual life satisfaction as potential co-benefits of rebound effects. In order to analyse the first dividend, a mixed methods approach is adopted, enabling two models of time use rebound effects to be applied. First, semi-standardised interviews reveal that environmentally ambiguous substitutions of activities occur following a reduction in working hours. Second, estimates for Germany from national surveys on time use and expenditure show composition effects of gains in leisure time and income loss. For the latter, we estimate the marginal propensity to consume and the marginal propensity to time use. The results show that time savings due to a reduction in working time trigger relevant rebound effects in terms of resource use. However, both the qualitative and quantitative findings put the rebound effects following a reduction in working time into perspective. Time use rebound effects lead to increased voluntary social engagement and greater life satisfaction, the second and third dividends.
Wissen stärkt die Region
(2013)
In diesem Artikel erläutert Michael Kopatz, warum Projekte kooperativen Wirtschaftens (wie beispielsweise Regionalwährung, Tauschringe und Energiegenossenschaften) ihr wahres Potenzial in puncto Klimaschutz, Ressourcenschonung und lokaler Wertschöpfung erst dann entfalten können, wenn Kommunen sie systematisch unterstützen.
Er fordert, dass Projekte der Gemeinwohlökonomie nicht länger nur wohlwollend von politischen Entscheidungsträger(inne)n wahrgenommen werden, sondern dass ein Handlungskonzept zur systematischen Förderung geschaffen wird - eine Wirtschaftsförderung 4.0 sozusagen, die er in seinem Beitrag beispielhaft entwickelt und erläutert.
Managing solid waste is one of the biggest challenges in urban areas around the world. Technologically advanced economies generate vast amounts of organic waste materials, many of which are disposed to landfills. In the future, efficient use of carbon containing waste and all other waste materials has to be increased to reduce the need for virgin raw materials acquisition, including biomass, and reduce carbon being emitted to the atmosphere therefore mitigating climate change. At end-of-life, carbon-containing waste should not only be treated for energy recovery (e.g. via incineration) but technologies should be applied to recycle the carbon for use as material feedstocks. Thermochemical and biochemical conversion technologies offer the option to utilize organic waste for the production of chemical feedstock and subsequent polymers. The routes towards synthetic materials allow a more closed cycle of materials and can help to reduce dependence on either fossil or biobased raw materials. This chapter summarizes carbon-recycling routes available and investigates how in the long-term they could be applied to enhance waste management in both industrial countries as well as developing and emerging economies. We conclude with a case study looking at the system-wide global warming potential (GWP) and cumulative energy demand (CED) of producing high-density polyethylene (HDPE) from organic waste feedstock via gasification followed by Fischer–Tropsch synthesis (FTS). Results of the analysis indicate that the use of organic waste feedstock is beneficial if greenhouse gas (GHG) emissions associated with landfill diversion are considered.
A future-oriented and sustainable "Leasing Society" is based on a combination of new and innovative serviceoriented business models, changed product and material ownership structures, increased and improved eco-design efforts, and reverse logistic structures. Together these elements have the potential to change the relationship between producers and consumers, and thereby create a new incentive structure in the economy regarding the use and re-use of resources. While the consumer in a leasing society buys a service (instead of a product), the producer in a leasing society retains the ownership of the product (instead of selling it) and sells the service of using the product. This creates producer incentives to re-use, remanufacture, and recycle products and materials and could become a cornerstone of the circular economy, depending on how the leasing society is implemented. While a predominantly positive picture of the success of a leasing society model and related business cases emerges from the bigger part of the available literature, this paper argues that the resource efficiency of respective business cases is highly dependent on the specific business case design. This paper develops a more cautious and differentiated definition of the leasing society by discussing relevant mechanisms and success factors of leasing society business cases. The leasing society is discussed from a micro business-oriented and a macro environment-oriented perspective complemented by a discussion of conditions for successful business models that reduce environmental impacts and resource footprints.
Ein sorgsamer Umgang mit natürlichen Ressourcen gehört zu den Kernthemen von Industrial Ecology. Mit der jeweiligen Betrachtungsebene, vom Unternehmen bis zur globalen Ebene, wechseln die Herausforderungen, Methoden und Lösungsansätze. Gibt es auch Indikatoren, die skalenübergreifend angewandt werden können?
Poor sustainability and increasing economic shortcomings in fossil raw material use besides further technical developments of substitutes lead to a growing potential for CO2-utilisation. Hence, we balanced CO2-based methane and methanol production in a life cycle assessment and identified CO2-utilisation as a greenhouse gas saving method. However, it requires a lot of renewable energy.
Urban mining
(2008)
This study aims to investigate whether, to what extent and how a transition toward integrated flood management has taken place in the Dongting Lake area at the middle Yangtze. Accordingly, we conducted a longitudinal research of its flood management (1949–2009). We developed an analytical framework linking regime components to two societal learning types (double and triple-loop learning) that are key to a regime transition. Our study shows that the transition toward integrated flood management has already started, but the whole regime transformation will still take time to complete, due to, for example, the not-yet-ready decision-making processes that shape the structure changes as well as the incompatibilities between what is on paper and real implementation. To understand how the regime transition took place, we investigated where and how triple-loop learning was initiated as well as how so-called "informal learning processes" has contributed to the transition of Dongting flood management.
Umweltverträglichkeitsprüfung und strategische Umweltprüfung als Instrumente des Ressourcenschutzes
(2014)
Vor dem Hintergrund der aktuellen Ressourcenschutzdiskussion wird im Beitrag erläutert, wie Ressourcenschutzbelange in den bestehenden UVPG-Schutzgütern, aber auch darüber hinaus in der Umweltprüfung stärker berücksichtigt werden können. In diesem Zusammenhang stellen die räumlichen und zeitlichen Systemgrenzen der Umweltprüfung eine besondere Herausforderung dar. Es werden erste Ansätze dargestellt, wie ressourcenbezogene Umweltwirkungen und stoffliche und energetische Inanspruchnahmen in die Planungspraxis übernommen werden können.
