Ralf Seppelt (Prof. Dr.) studied applied mathematics at the Technical University Clausthal Zellerfeld, Germany, obtained his doctorate degree at the Technical University Braunschweig, Germany, in agroecology and systems analysis where he worked as research assistant and lecturer at Institute for Geoecology. After several research visits at the Gund Institute for Ecological Economics, Burlington and Maryland, USA, as well at the CSIRO in Canberra, Australia, he was appointed full professor for landscape ecology and Resource Economics at Martin-Luther University Halle-Wittenberg, where he lectures course on Environmental Modelling. He is head of the department for Computational Landscape Ecology. In the BMBF programme on "Sustainable Land Management" he coordinated the synthesis project GLUES “Global Assessment of Land Use Dynamics on Greenhouse Gas Emissions and Ecosystem Services”. His major research focus is land resources management based on integrated simulation and modelling systems. He thus is interested in the interactions and interrelationship of anthropheric and biospheric processes. This requires methodological developments in landscape ecology such as model integration, hybrid model systems and scales in space and time. He published various books and over 100 papers, see researcherID.
For the Intergovernmental "Science Policy Platform on Biodiversity and Ecolosystem Services" (IPBES) he worked as lead author for the Global Assessment and currently is coordinating lead author for the Nexus Assessment.

Having acquired a long-standing and in-depth understanding of human-environmental feedbacks at a regional scale, mostly with the scope on ecosystem service research [see most important references #1], in the recent years I seeked to apply that knowledge to global scale issues of human appropriation of natural resources. Together with my team we (a) identified global limitations of renewable resource production , devloped and tested a novel approaches to map global socio-environmental systems with respect to land management  and tested new approaches to assess ecosystem service valuations at a globale scale [4, 12]. Especially the study on the global value of pollination services  gained high attraction inside but also outside academia, was cited and reprinted in various policy documents (such the Summary for Policy Makers (SPM) of the as IPBES Pollination Assessment) as well as utilized by NGOs (Greenpeace).
Given these results, I aimed at (a) conceptually understanding the limitations human societies are faced with, given the decline in biodiverity [5,6]; (b) established globale scale synthesis studies to obtain data and information on that feedbacks  including best practive recommendations to support meta-analysis studies ; and (c) investigated how emerging remote sensing can support such research . We also started to develop the first model application that consistently analyses global agroeconomy, agricultral productivity as well as its impacts on biodiersity . Beyond this, I started to work on the societal part of human environment interaction and its model development [10,13].
Finally, I was and still am concerned about the way how we conduct science and how the scientific system is slowly transitioning in a globalized world . In that paper, I layout my vision of a less accellerating but higher quality science.
Vision: This ERC proposal MODUS I intentially focus on theory building and conceptual thinking, which is to my understanding crucially lacking in many fields of environmental research. With this, I somehow return to the origin of my scientific career, mathematics, philosophy and conceptional thinking.

CredoMy lectures and courses are always driven by the strong belief, that scientific progress and innovation are possible only, if recent research is presented in education and by the fact that data gathering in field, conceptional modelling as well as mathematical modelling and numerical analysis needs to be thought in an overall concept. Thus I always try to show my students in science its always a challenging question to start with, to continue with data collection and finally apply a modelling exercise for analysis. Only this enables us to assess simulation results correctly and enables us to teach interdisciplinary research.
