Multi-Scale Governance of Sustainable Natural Resource Use—Challenges and Opportunities for Monitoring and Institutional Development at the National and Global Level
(2016-08-09)
In a globalized economy, the use of natural resources is determined by the demand of modern production and consumption systems, and by infrastructure development. Sustainable natural resource use will require good governance and management based on sound scientific information, data and indicators. There is a rich literature on natural resource management, yet the national and global scale and macro-economic policy making has been underrepresented. We provide an overview of the scholarly literature on multi-scale ...

Potenzialanalyse der Fördermaßnahme CO₂-WIN
(2022-01)
Die Nutzung von CO₂ als Rohstoff ist ein vielversprechender Weg, um fossilen Kohlenstoff in verschiedensten Anwendungen zu substituieren, emittiertes CO₂ produktiv einzusetzen und Kohlenstoff vermehrt im Kreislauf zu führen. Im Rahmen der Fördermaßnahme CO₂-WIN wird deshalb in insgesamt 15 verschiedenen Forschungsprojekten untersucht, wie CO₂ als Rohstoff zur Produktion von werthaltigen Produkten eingesetzt werden kann. In diesem Dokument wird die Herangehensweise zur Analyse und Berechnung der zukünftigen Potenziale, ...

Bestimmung des Materialfußabdrucks mit ökobilanziellen Methoden und Softwarelösungen
(2019-05)
Die Bestimmung des Materialfußabdrucks ist wichtig, um die Ressourcenproduktivität jedes Unternehmens und letztlich der Gesamtwirtschaft wirksam steigern zu können. Deshalb wurde eine methodische Handreichung zur Bestimmung des Materialfußabdrucks von Produkten und Infrastrukturen entwickelt und die Vorgehensweise am Beispiel der CO2-Nutzung erläutert. Der Konzepthintergrund, die Hauptindikatoren und die Verwendung von opensource Software mit einschlägigen LCA-Datenbanken werden vorgestellt.

Multicriteria Analysis Methods for enhanced Result Interpretation in Life Cycle Assessment
(2021-03)
In this document the problem of trade-offs between indicators in Life Cycle Assessment (LCA) studies is explained in more detail as well as the requirement of MCA methods to accommodate them. Furthermore, the four environmental footprints in combinations with certain other indicators are proposed as a common minimum-set of indicators to harmonize LCA-studies and to ensure their comparability. Important rules for the conduction of an LCA for CO2 utilization technologies are also explained. In the next step, methods ...
Dissertation
CO₂ as Carbon Source
(2022-04)
This thesis examines several aspects of the use of CO₂ as a carbon source for the chemical industry in Germany. The analysis focuses on the usage potential for CO₂ in the chemical and plastics industries, the current and future competitiveness for the production of CO₂ based chemicals in Germany and the characteristics of a CO₂ based value chain for polymer products. To investigate the different aspects, multiple methods of system analysis are applied, which investigate environmental and economic aspects of CO₂-based ...
Habilitation
Impact on climate by land-atmosphere interactions
(2022)
This synthesis of the cumulative habilitation explores the uncertainties of the impact of land-atmosphere interactions due to land use and cover change (LUCC) on the regional and local climate. The results are published in several papers of climate, environmental and atmospheric journals. Efficient emission reduction policies are needed in order to reduce the increase in the rate of climate change intensification with increasing greenhouse gas emissions. This requires the development of mitigation and adaptation ...

Decision‐Making in Public Good Dilemmas: Theory and Agent‐Based Simulation
(2013-05-14)
In many real world contexts individuals find themselves in situations where they have to decide between options of behaviour that serve a collective purpose or behaviours which satisfy one’s private interests, ignoring the collective. In some cases the underlying social dilemma (Dawes, 1980) is solved and we observe collective action (Olson, 1965). In others social mobilisation is unsuccessful. The central topic of social dilemma research is the identification and understanding of mechanisms which yield to the observed ...

Modeling the interplay between land use, bioenergy production and climate change
(2010-08-09)
Land use has become a force of global importance, considering that 34% of the Earth’s ice-free surface was covered by croplands or pastures in 2000. The expected increase in global human population together with eminent climate change and associated search for energy sources other than fossil fuels can, through land-use and land-cover changes (LUCC), increase the pressure on nature’s resources, further degrade ecosystem services, and disrupt other planetary systems of key importance to humanity. This thesis presents ...

Modelling of global crop production and resulting N2O emissions
(2006-04-18)
Landwirtschaft spielt eine zentrale Rolle im Erdsystem. Sie trägt durch die Emission von CO2, CH4 und N2O zum Treibhauseffekt bei, kann Bodendegradation und Eutrophierung verursachen, regionale Wasserkreisläufe verändern und wird außerdem stark vom Klimawandel betroffen sein. Da all diese Prozesse durch die zugrunde liegenden Nährstoff- und Wasserflüsse eng miteinander verknüpft sind, sollten sie in einem konsistenten Modellansatz betrachtet werden. Dennoch haben Datenmangel und ungenügendes Prozessverständnis dies ...

A Modeling Analysis of Changing Global Land Use as affected by Changing Demands for Wood Products
(2010-01-08)
The 21st century has brought new challenges for forest management at a time when globalization in world trade is increasing and global climate change is becoming increasingly apparent. In addition to various goods and services like food, feed, timber or biofuels being provided to humans, forest ecosystems are a large store of terrestrial carbon and account for a major part of the carbon exchange between the atmosphere and the land surface. Depending on the stage of the ecosystems and/or management regimes, forests ...
