    Towards sustainable resource management in the European Union (2002)
    Wuppertal : Wuppertal Institut für Klima, Umwelt, Energie | Wuppertal : Wuppertal Institut für Klima, Umwelt, Energie
    Details
    Publication Date: 2022-02-18
    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.

    Mortality of Asterias rubens and Ophiura ophiura discarded in the Nephrops fishery of the Clyde Sea area, Scotland (2001)
    In:  EPIC3ICES Journal of Marine Science, 58, pp. 531-542

    Description: The Clyde Sea Nephrops fishery produces large amounts of invertebrate discards. Of these, up to 80% (by numbers) are echinoderms, including the starfishAsterias rubens and the brittlestar Ophiura ophiura. The short- and longer-term mortality of these species was determined after trawling in order to gain reliableestimates of trawl-induced mortality. Short-term mortality was assessed after trawling and periods of aerial exposure on deck, and ranged from 0-31%, with A.rubens showing lower mortality. Mortality of haphazardly collected echinoderms of various sizes and degrees of damage was monitored over one month todetermine longer-term mortality. The effects of injury on starfish survival were also examined, as were the effects of trawling and aerial exposure on O. ophiurasurvival and A. rubens righting time. Injured A. rubens had a significantly higher long-term mortality (22-96%) than controls (4%). Trawling and aerial exposuresignificantly increased righting times of A. rubens, implying susceptibility to stress and an increased risk of predation. Moribund A. rubens developed white lesionscontaining bacteria (Vibrio metschnikovii and Acinetobacter sp.) and mortality rates only stabilised in the third week after trawling. In contrast, all trawled O. ophiuradied within 14d. Immediate re-immersion in sea water resulted in lower, but nevertheless high, mortality (91%). Our results suggest that post-trawling mortality ofdiscarded echinoderms has been underestimated in the past.

    Cognitive and institutional perspectives of eco-efficiency : a new research landscape towards Factor Four (or more) (2002)
    Wuppertal : Wuppertal Institut für Klima, Umwelt, Energie | Wuppertal : Wuppertal Institut für Klima, Umwelt, Energie
    Details
    Publication Date: 2022-02-18
    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.

    Survival of decapod crustaceans discarded in the Nephrops fishery of the Clyde Sea area, Scotland (2001)
    In:  EPIC3ICES Journal of Marine Science, 58, pp. 163-171
    Details

    Description: The Clyde Sea Nephrops fishery produces large amounts of invertebrate discards. Of these, as much as 89% are decapod crustaceans, including the swimmingcrab Liocarcinus depurator (Linnaeus, 1758), the squat lobster Munida rugosa (Fabricius, 1775) and the hermit crab Pagurus bernhardus (Linnaeus, 1758). Theshort-term mortality of these species was assessed following trawling and periods of aerial exposure on deck (16-90min), and ranged from 2-25%, with Pagurusbernhardus showing the lowest mortality. Two experiments were performed to determine the longer-term survival of trawled decapods compared to those withexperimentally ablated appendages. Deliberately damaged decapods had a significantly lower longer-term survival (ca. 30%) than controls (72-83%). Survival oftrawled Liocarcinus depurator that had been induced to autotomize two appendages was slightly lower (74%) compared with intact creel-caught animals (92%).Mortality rates stabilised about 10d after trawling. Our results suggest that post-trawling mortality of discarded decapod crustaceans has been underestimated in thepast, owing to inadequate monitoring periods.
