Die Forschungsgruppe Biodiversit\u00e4ts\u00f6konomie fokussiert sich darauf, die wissenschaftliche Grundlage f\u00fcr Nachhaltigkeit in den Beziehungen zwischen Mensch und Natur zu verbessern, indem sie die nachhaltige Nutzung erneuerbarer nat\u00fcrlicher Ressourcen (z. B. Meeresfischerei, Weideland, W\u00e4lder) und die Erhaltung der Biodiversit\u00e4t von der regionalen bis zur globalen Ebene untersucht.<\/p>\n \n <\/div>\n <\/div>\n\n \n <\/div>\n\n <\/div>\n<\/div>\n\n

Wir untersuchen, wie wirtschaftliche Anreize das Verhalten gegen\u00fcber der Natur beeinflussen, was Nachhaltigkeit – verstanden als Gerechtigkeit in den Beziehungen zwischen Mensch und Natur – bedeutet und wie wirtschaftspolitische Instrumente zu diesem Ziel beitragen k\u00f6nnen. Unsere methodische Expertise umfasst quantitative \u00f6kologisch-\u00f6konomische Modellierung, dynamische Optimierung, Statistik, \u00f6konomische Experimente, konzeptionelle Modellierung, Spieltheorie und Kapitaltheorie.<\/p>\n<\/div>\n <\/div>\n <\/div>\n <\/div>\n<\/div>\n\n\n

\n Towards a comprehensive valuation of natural capital in Germany: Methods and approaches to deal with limited information and uncertainty (ValuGaps) \n \n <\/svg>\n <\/div>\n

 <\/p>\n

Biodiversity and natural capital contribute fundamentally to human well-being. So far, societal decision-making only partly takes these values into account. One major reason are large information gaps and uncertainties. The few existing original valuation studies have not been systematically selected, typically consider only a subset of values, and treat ecological-economic dynamics and uncertainties only implicitly.\u00a0ValuGaps\u00a0<\/em>responds to the need for comprehensive, reliable, and scalable values of natural capital and biodiversity for societal decision-making, as experienced by public authorities in Germany, especially the German Environment Agency (UBA) and the German Federal Agency for Nature Conservation (BfN).<\/p>\n

 <\/p>\n

ValuGaps<\/em>\u00a0considers multi-dimensional economic, relational, and health values and asks the following questions:<\/p>\n

    \n
  1. Where do societal decision-makers and stakeholders face the largest information gaps and uncertainties with respect to different values of biodiversity and natural capital?<\/li>\n
  2. How to scale, transfer, and bridge different types of values across (i) space and time, (ii) groups of beneficiaries, and (iii) types of ecosystems in a practical, scientifically and normatively sound way? By means of integrated ecological-economic modelling, behavioural experiments, and surveys, we specifically ask\n
      \n
    1. What are the key parameters required to value natural capital in a scalable and transferable way, and how can their values be quantified or constrained?<\/li>\n
    2. How do uncertainties propagate when scaling, transferring or bridging values?<\/li>\n<\/ol>\n<\/li>\n
    3. How can societal decision-makers make best use of valuation, and how do and how should they deal with uncertainties?<\/li>\n<\/ol>\n

       <\/p>\n

      ValuGaps<\/em>\u00a0will develop the interdisciplinary scientific basis for comprehensively taking into account natural capital values in policy making, accounting and planning. The approach will be exemplified and tested for grasslands as the prime case study, and for smaller case studies on temperate forests, marine fish and urban green space. As a transdisciplinary project where scientists closely cooperate with the key federal agencies in the domain, UBA and BfN, and by establishing a reference-stakeholder network,\u00a0ValuGaps<\/em>\u00a0will significantly contribute to mainstreaming the value of biodiversity in decision-making, a political commitment under the CBD Aichi Target 2.<\/p>\n

      \n Marine ecological-economic systems in the Western Baltic Sea and beyond: Shifting the baseline to a regime of sustainability (marEEshift) \n \n <\/svg>\n <\/div>\n
      \n

      marEEshift pursues the following overall scientific aims:<\/p>\n

      1. identify processes that increase or decrease the resilience of marine ecological-economic systems.<\/p>\n

      2. identify and initiate measures, institutions, and processes that could foster a resilient ecological-economic system of marine resource use in a regime of sustainability. This may require a regime shift from the current state of over-use towards a new resilient regime of sustainability.<\/p>\n

      To achieve these aims, we will study historical regime shifts in the Western Baltic Sea and beyond. We will explore the combinations of ecological, environmental (incl. climate-related), economic, social, and political drivers that have caused tipping points in the Western Baltic Sea and in cod-fisheries throughout the Northern Atlantic in the past.<\/p>\n

      In addition to that, we will study the effects of environmental change as well as multi-species interactions and multiple stakeholders on the resilience of the Western Baltic marine ecological-economic system, where commercial and recreational fisheries on cod and herring interact.<\/p>\n

      Besides analyzing what a regime of sustainability would be in the context of this specific ecological-economic system, we will explore the potential for a shift towards a regime of sustainability for the Western Baltic as a model case.<\/p>\n

      This project is funded by the Federal Ministry of Education and Research for a period of three years.<\/p>\n

      \n Food security and sustained coastal livelihoods through linking land and ocean (FOCUS) \n \n <\/svg>\n <\/div>\n
      \n

      Sustainable food production is a central element of a future bioeconomy. However, many food production systems on land and in the oceans are under pressure from intensive human use and global environmental changes.<\/p>\n

      FOCUS aims to globally assess the economic effects of climate change on marine ecosystem services and agriculture. Together with partners from the Potsdam Institute for Climate Impact Research (PIK), Climate Impacts and Vulnerabilities and Dalhousie University, we will couple a global agricultural sector and land-use model in combination with a new global bio-economic fisheries model to quantify climate change effects on food production, food security and rural livelihoods for the coastal areas around the world.\u00a0 In collaboration with practitioners, we will develop policy approaches for integrating a well-managed, linked land-ocean system into the bioeconomy.<\/p>\n\n <\/div>\n <\/div>\n

      \n Scenarios of Marine Biodiversity and Evolution under Exploitation and climate change (SOMBEE) \n \n <\/svg>\n <\/div>\n
      \n

      SOMBEE addresses the role of eco-evolutionary dynamics and their consequences for the sustainable exploitation of fish resources in the future. To this end, we will build and test scenarios of the combined pressure of fishing and climate change on both intra- and inter-specific marine biodiversity, by explicitly modelling the phenotypic plasticity of fish life-history traits, their selection and adaptive evolution, and their genetic drift for multiple interacting species. The objectives are to:<\/p>\n
