Im folgenden Beitrag untersuchen wir die Bürgerbeteiligung im Projekt InnovationCity Ruhr - Modellstadt Bottrop. Im Frühjahr 2010 hat der Initiativkreis Ruhr einen Wettbewerb ausgerufen, bei dem die "Klimastadt der Zukunft" gefunden werden sollte. Ausschlaggebend für den Sieg der Ruhrgebietsstadt war das vorgelegte Konzept, welches Gesellschaft, Wirtschaft und Wissenschaft verbindet. Ziel von InnovationCity Ruhr ist es die CO2-Emmissionen in der Stadt bis 2020 zu halbieren und somit eine Vorbildfunktion zur sozial-ökologischen Transformation für das gesamte Ruhrgebiet einzunehmen. Anhand der (Zwischen-) Ergebnisse zweier Untersuchungen (Best 2013; Roose 2014) werden wir veranschaulichen, wie die Bottroper Bevölkerung die Beteiligungsmöglichkeiten im Projekt wahrnimmt. Darüber hinaus decken wir Hemmschwellen auf und geben Empfehlungen zu einer verbesserten Aktivierung der und breiten Beteiligung durch die Bürgerinnen und Bürger.
Access to sustainable and affordable energy services is a crucial factor in reducing poverty in developing countries. In particular, small-scale and community-based renewable energy projects are recognized as important forms of development assistance for reaching the energy poor. However, to date only a few empirical evaluations exist which analyze and compare the impact of these projects on local living conditions and their sustainability ex-post implementation.
To better understand the impacts and the conditions that influence sustainability of these projects, the research presented in this paper evaluated 23 local development projects post implementation. By applying an standardized evaluation design to a cross-sectional sample in terms of renewable energy sources (solar, wind, biomass, hydro), user needs (electricity, food preparation, lighting, productive uses), community management models, finance mechanisms and geographical locations, the review results provide valuable insights on the underlying conditions that influence the success or failure of these small-scale local energy interventions. The empirical evidence suggests that the sustainability of small-scale energy implementations (≤100 kW) in developing countries is determined by the same factors, independent of the socio-cultural, political and ecological context. These findings allow to better predict the long-term success of small sustainable energy projects in developing countries, this can help to improve project designs and increase the certainty for future investment decisions.
In the debate about the transformation process towards sustainability manifold eco social economic concepts are discussed. Most of them lay claim to democracy, to processes of inclusion of all who are affected. But do alternative concepts automatically lead to democracy, overcoming hierarchies, power and exclusion? Based on this question, the article discusses two eco social concepts: Vorsorgendes Wirtschaften and Small new Social Contracts. It throws the light on traps like repressive or instrumental forms of inclusion and ends with three clues for a transformative democratic way to sustainability.
In recent decades, better data and methods have become available for understanding the complex functioning of cities and their impacts on sustainability. This review synthesizes the recent developments in concepts and methods being used to measure the impacts of cities on environmental sustainability. It differentiates between a dominant trend in research literature that concentrates on the accounting and allocation of greenhouse gas emissions and energy use to cities and a reemergence of studies that focus on the direct and indirect material and resource flows in cities. The methodological approaches reviewed may consider cities as either producers or consumers, and all recognize that urban environmental impacts can be local, regional, or global. As well as giving an overview of the methodological debates, we examine the implications of the different approaches for policy and the challenges these approaches face in their application on the field.
