    Description: A policy framework for sustainable resource management (SRM) is required both to guarantee the materials and energy supply of the EU economy and safeguard the natural resource basis in the future. Goals and strategies for sustaining the metabolism of the economy are described. Data are presented on the material throughput and physical growth of the EU's economy, on total material requirements (TMR), its composition, the decoupling from economic growth, and the increased shift to other regions. A first future target Material Flow Balance (t- MFB) of the EU is outlined. Detailed data reveal the "top ten" resource flows. Policy design for SRM should aim at an integrated and balanced approach along the material flow, comprising resource extraction, the product cycle and final waste disposal. Strategies and potential instruments to manage fossil fuels, metals and industrial minerals, construction minerals and excavation are discussed. Possible priorities and examples are given for target setting, focusing on limited expansion of built-up area, reduced use of non-renewables, increased resource productivity, and shift to sustainable cultivation of biomass.

    Description: For answering questions concerning anthropogenic impacts on tropical forest developmentthe individual-oriented and process-based forest growth model Formind2.0 wasdeveloped. It simulates the spatio-temporal dynamics of uneven-aged mixed forest standsin areas of one hectare to several km^2. The model describes forest dynamics as a mosaicof interacting forest patches of 20 m^2×20 m^2 in size. Within these patches trees are notspatial-explicitly distributed, and thus all compete for light and space following the gapmodel approach. Tree species diversity is aggregated into 5-20 plant functional types(PFT) on the basis of species maximum tree height and successional status. The carbonbalance of each individual tree including photosynthesis and respiration is modelled explicitly.Thus, we can match measured diameter increment for different PFT, size and light conditionsaccurately. Allometric relationships connect above-ground biomass, stem diameter,tree height and crown dimensions. Beside increasing mortality through self-thinning indense plots one of the main processes of mortality is gap creation by falling of large trees.This process as well as seed dispersal from mature trees interlinks neighbouring plots witheach other.The model was parametrised for three different sites in South-East Asia and South-America:Sabah (Malaysia), Venezuela, and French Guiana. Model accuracy is testedwith growth data from permanent sampling plots in Sabah. Sensitivity of various resultvariables on variation of most parameter values is tested and give important insights intogeneral model behaviour.Two examples of anthropogeneous impacts on tropical forest dynamics are managementpractise and fragmentation, both of major concern. Following applications are performed:Growth and yield of Venezuelan rain forest under various logging methods, intensitiesand cycles are analysed for their ustainability.Effects of logging (method and cycles), fragmentation and recruitment assumptionson forest dynamics in Sabah are discussed.Finally, fragmentation impacts on mortality and recruitment are simulated and theireffects on forest dynamic and biomass loss are evaluated for a forest site in French Guiana.

    Description: The paper sketches out a theoretical framework for analysing the interplay between eco-efficiency, cognition and institutions. It derives from analytical shortfalls of the prevailing literature, which features strongly engineering and business economics, by using insights from New Institutional Economics, from Cognitive Sciences and, partly, from Evolutionary Economics. It emphasises the role cognition and institutions play in the adoption of "green" technologies by firms. A cognitive perspective derives from recent research on simple heuristics and context-based rationality; it is proposed that those recent findings can serve to analyse decision-making of individual actors or firms and, thus, should complement economic analysis. A second proposition is that eco-efficiency and normative rules such as a Factor Four strongly rely upon institutions, i.e. the ability of institutions to evolve over time and the development of those institutions that are most appropriate to enhance technological change. In this regard, business institutions and competition are crucial, but regulatory needs remain in order to safeguard continuity of knowledge creation. The framework allows for an analysis why overall adoption of eco-efficiency still can be considered relatively slow and why some markets and firms are far ahead. As a brief case study the article reflects upon German waste law’s ability to enhance eco-efficiency.
