Agricultural Entrepreneurs' Decision Making and Structural Change: An Experimental Approach

The rational calculus of farmers assumed in many agricultural economic models is unrealistic and non-predictive of their actual decision making. Understanding structural change in agriculture can thus be improved via a realistic modeling of the decision making by agricultural entrepreneurs. Specifically, slow disinvestment (i.e., postponing farm exit), persistence of market structures (i.e., failure to reallocate land plots towards higher efficiency), and more generally characterizing the decision making of farmers are crucial for a better understanding of structural change and policy advice. We apply economic experiments to better understand such disinvestment choices, land markets with economies of scale and private opportunity costs, different auction and bargaining forms to improve allocation efficiency of land markets, and to generally characterize the decision making of farmers.

Forest functions arrangement with the CBD's Ecosystem Approach - A study on the Bengawan Solo River Basin, Java, Indonesia

The natural capital of forests consists to a great extend of the forests environmental functions for human well-being, which not only include goods and services (source and sink functions) but also include life-support functions that reflect ecosystem performance (ecosystem functioning). Shifting the management approach from a traditional one to one that is more aware of the ecosystem complexity, the idea of 'ecosystem functioning is appearing to tackle gradual declines of ecosystem functions. Within CBDs framework, the Ecosystem Approach has been introduced on account of the necessity for open decision making with strong links between all stakeholders and the latest scientific knowledge due to uncertainty and unpredictability in nature. The Ecosystem Approach is still in need of further elaboration, even though as a concept Ecosystem Approach has been widely accepted. To aim forest enhancement, this approach has been regarded as the most feasible concept for the study area, the Bengawan Solo River Basin - Java, Indonesia. Therefore the principles and operational guidelines will be used to analyse and evaluate the current forest management in those areas of the Bengawan Solo River Basin, in which ecosystem function is the basis for forest development area. This research focuses on ecological functions of forests at various levels of ecosystem management planning, from the forestry sectors point of view.

Verwertung von PUMA-Produkten

Im April 2012 führte PUMA das Rücknahmesystem Bring Me Back ein. Seither können Kunden in PUMA Stores weltweit gebrauchte Produkte zurückgeben, die dann durch die Firma I:CO der Weiterverwendung und Verwertung zugeführt werden. Auch die Produkte der neuen recyclefähigen und biologisch abbaubaren PUMA-InCycle-Kollektion, die seit März 2013 auf dem Markt sind, werden so erfasst. Hierzu gehört etwa das recycelbare PUMA Track Jacket, das zu 98 Prozent aus Polyester aus gebrauchten PET-Flaschen besteht. Der PUMA-Rucksack aus Polypropylen wird nach Gebrauch an den ursprünglichen Hersteller zurückgegeben, der das Material wieder zu neuen Rucksäcken verarbeitet. Durch solche Neuentwicklungen will PUMA seine Planungs- und Entscheidungsbasis verbessern. Deshalb hat sie bifa mit der Analyse abfallwirtschaftlicher Optionen für gebrauchte PUMA Produkte beauftragt. bifa untersuchte hierzu Referenzprodukte und Optionen für die Erfassung und Sortierung von Produkten und Materialien. 35 Pfade mit unterschiedlichen Verwertungs- und Beseitigungsansätzen wurden entwickelt und bewertet. Die Realisierungschancen der Pfade wurden dann dem zu erwartenden Nutzen insbes. für die Umwelt gegenübergestellt. Dabei wurde zwischen gut entwickelten und wenig entwickelten Abfallwirtschaften (Waste-Picking-Szenario W-P-Szenario) unterschieden. Es zeigte sich, dass Pfade, die im Szenario Abfallwirtschaft ökologisch nachteilig sind, im W-P-Szenario durchaus vorteilhaft sein können. Im W-P-Szenario sind zudem Pfade realisierbar, die in entwickelten Abfallwirtschaften keine Chance hätten. Die moderne Abfallverbrennung ist für W-P-Szenarien ökologisch vorteilhaft, aber dennoch eine schwierige Option. In entwickelten Abfallwirtschaften sollten Sammlung und Wiedereinsatz gebrauchter Schuhe und Textilien weiterentwickelt werden. Die folgenden generellen Empfehlungen wurden gegeben: - Der Einsatz von Recyclingmaterialien in PUMA-Produkten ist aus ökologischer Sicht zu empfehlen. Diese Erkenntnis wird auch durch die Ergebnisse der ersten ökologischen Gewinn-und-Verlust-Rechnung von PUMA belegt. Über die Hälfte aller Umweltauswirkungen entlang der gesamten Produktions- und Lieferkette des Unternehmens werden bei der Herstellung von Rohmaterialien verursacht - Das Produktdesign sollte auch für bestehende Verwertungspfade optimiert werden, da realistischerweise nur ein Teil der Produkte über das Sammelsystem erfasst werden kann - Die ökologischen Vorteile von Produkten, die aus nur einem Material bestehen, kommen nur dann zum Tragen, wenn das Produkt nach Gebrauch aussortiert und das Material tatsächlich recycelt wird - Biol. abbaubare Produkte können auch Nachteile haben, zum Beispiel die schnellere Entwicklung von klimaschädlichem Methan bei ungeordneter Deponierung - Eine Verlängerung der Produktlebensdauer über den gesamten Lebenszyklus einschl. der Verwendung als Gebrauchtprodukt ist der effektivste Weg, Umweltlasten zu reduzieren.

Probabilistic approaches for assessing environmental risks of pesticides

Current methods for risk assessment are mostly 'deterministic'. This means they treat factors such as the toxicity of pesticides as if they were fixed, and precisely known. But in the real world, factors such as toxicity are not fixed but variable. For example, the same pesticide could be more toxic to some species of wildlife, and less toxic to others. What's more, the factors affecting risk are not precisely known but uncertain. For example, toxicity is measured for only a very small number of species, so scientists have to estimate toxicity to all the other species that we want to protect. Current methods for risk assessment try to allow for variability and uncertainty by using 'fixed safety factors', but this fails to give a complete description of the full range of the possible risks. Also, it is difficult to decide how big the safety factors should be. Probabilistic approaches enable variation and uncertainty to be quantified, mainly by using distributions instead of fixed values in risk assessment. A distribution describes the range of possible values (e.g. for toxicity), and shows which values within the range are most likely. The result of a probabilistic risk assessment can also be shown as a distribution, showing the range of environmental impacts that are possible, and which impacts within that range are most likely. This should provide a better basis for making decisions about pesticide risks, because the full range of possible outcomes can be taken into account. The main work of the EUFRAM project is done by a core partnership of 27 organisations from government, industry and academia, and comprises three main parts. 1. Development of a draft framework of basic guidance for risk assessors. The topics to be addressed include: - role and outputs of probabilistic assessments - methods of uncertainty analysis - probabilistic methods for small datasets - how to report and communicate results - how to validate probabilistic methods - how to improve access to existing data - requirements for probabilistic software and databases. - The framework will also include case studies of probabilistic risk assessment, showing how the methods can be applied to assessing impacts of pesticides on terrestrial and aquatic organisms. The first draft of the framework will be published at the end of 2004. 2. End-user testing. - In 2005-2006, the draft framework was subjected to extensive testing and refinement. A series of three workshops was organised for potential users, who were encouraged to trial the framework in their own organisations. Feedback from the users was used to refine the framework, and it is intended that the final version will be suitable for adoption as standard guidance at the European level.

Optimized Strategies for Risk Assessment of Chemicals based on Intelligent Testing (OSIRIS)

The proposed regulation concerning the registration, evaluation, authorisation and restriction of chemicals (REACH) requires demonstration of the safe manufacture of chemicals and their safe use throughout the supply chain. There is therefore a strong need to strengthen and advance human and environmental risk assessment knowledge and practices with regard to chemicals, in accord with the precautionary principle. The goal of the project OSIRIS is to develop integrated testing strategies (ITS) fit for REACH that enable to significantly increase the use of non-testing information for regulatory decision making, and thus minimise the need for animal testing. To this end, operational procedures will be developed, tested and disseminated that guide a transparent and scientifically sound evaluation of chemical substances in a risk-driven, context-specific and substance-tailored (RCS) manner. The envisaged decision theory framework includes alternative methods such as chemical and biological read-across, in vitro results, in vivo information on analogues, qualitative and quantitative structure-activity relationships, thresholds of toxicological concern and exposure-based waiving, and takes into account cost-benefit analyses as well as societal risk perception. It is based on the new REACH paradigm to move away from extensive standard testing to a more intelligent, substance-tailored approach. The work will be organised in five interlinked research pillars (chemical domain, biological domain, exposure, integration strategies and tools, case studies), with a particular focus on more complex, long-term and high-cost endpoints. Case studies will demonstrate the feasibility and effectiveness of the new ITS methodologies, and provide guidance in concrete form. To ensure optimal uptake of the results obtained in this project, end-users in industry and regulatory authorities will be closely involved in monitoring and in providing specific technical contributions to this project.

Reconciling Adaptation, Mitigation and Sustainable Development for Cities (RAMSES)

Objective: The RAMSES project will develop a rigorous, analytical framework for the implementation of adaptation strategies and measures in EU and international cities. It will develop a set of innovative methods and tools that will quantify the impacts of climate change and the costs and benefits of adaptation to climate change and thus provide the evidence to enable policy makers to design adaptation strategies. It integrates the assessment of impacts and costs to provide a much more coherent approach than currently exists. As major centres of population, economic importance, greenhouse gas emissions and infrastructure, RAMSES focuses on adaptation issues in cities. RAMSES will deliver: 1. A strategic frame for evidence-based adaptation decision-making. A pragmatic and standardised framework for decision making using comparable climate change impact assumptions, impact and adaptation costs while taking account of uncertainty. This will apply and combine smart and unconventional scientific methodologies. 2. Multi-level analysis as local administrative units, cities will be used to develop adaptation (and more generally sustainable development) strategies from the bottom-up/top-down, that can be aggregated to consider costs at the national, EU and international levels. 3. Quantification of adaptation costs a framework for assessment of full economic costs and benefits of adaptation (to date a woefully under-researched area). 4. Policy relevance and acceptance of adaptation measures city case studies and stakeholder engagement will ensure the relevance of the framework for policy makers and ensure adaptation measures become better accepted by other stakeholders. The frameworks will be converted into a user-friendly guide for stakeholders who need to prioritize adaptation and mitigation decisions. This reduces costs and enhances understanding and acceptance of adaptation. The data will be fed into the European Clearinghouse Mechanism to increase transparency/stakeholder access.
