is a helpful method for the formal integration of ecological and economic knowledge. A typical ecological-economic model consists of an ecological, and economic and a landscape component, which interact with each other in the one way or another. A popular application of ecological-economic models is the development and analysis of market-based biodiversity conservation instruments. Here the focus is often on the cost-effectiveness of an instrument, i.e. the instrument’s ability of achieving an ecological target at least costs, which involves the use of numerical optimisation.
For a good insight into the method I recommend my book
Here a video about the topic: A Brief History of (Ecological-economic) Modelling

Open PhD position
A PhD position is available within the research cluster Multiland that explores policies and strategies for biological pest control:
CALL FOR APPLICATIONS: PhD SCHOLARSHIP starting in 2022
PhD Programme Environmental and Resource Management
Research Cluster “Multifunctional Landscapes under Climate Change” (MultiLand)
Application Deadline October 10, 2021 - Start Scholarship/Programme in Cottbus: April 1, 2022
The idea of "multifunctional landscapes" is a promising concept for reconciling food production with the provision of ecosystem services and the protection of biodiversity. This idea is related to the concept of “ecological intensification” which according to a definition by FAO may be considered as “a knowledge-intensive process that requires optimal management of nature’s ecological functions and biodiversity to improve agricultural system performance, efficiency and farmers’ livelihoods.” In this research cluster, we investigate selected aspects of multifunctional landscapes respectively ecological intensification as a concept for combining food production with ecosystem service preservation (in particular pest control) and biodiversity conservation under climate change. Our study systems are fruit orchards in Brandenburg, Germany.
The research cluster combines the work of four PhD students from the fields of economics, ecology, climate science and modelling. All PhD students investigate the study system from a joint perspective but applying their disciplinary knowledge. Supervisors have excellent networks all over the world and all supervisors and PhD students work closely together. This call is for one PhD scholarship in ecological-economic modelling. Participants in the research cluster are as follows:
Helmholtz Centre for Environmental Research - UFZ, Dept. of Ecological Modelling, and Hon. Prof. of Ecological-Economic Modelling at BTU, Prof. Martin Drechsler
Topic “Ecological-economic modelling of biological pest control measures including adjacent semi-natural ecosystems in fruit orchards in a changing climate”: A spatially explicit agent-based model shall be developed to integrate information from the ecological, economic and climatological subprojects of Multiland, taking into account, among others, spatial interactions and human behaviour. The model shall be used to evaluate strategies for biological pest control.
The ideal candidate has good knowledge in the mathematical modelling of spatio-temporal processes, and computer programming in at least one higher language like C++, Python or Java. Some knowledge of one or more of the fields of economics, game theory and ecology is an advantage.
Department of Atmospheric Processes, BTU, Prof. Katja Trachte
Department of Environmental Economic, BTU, Prof. Frank Wätzold
Department of Ecology, BTU, Prof. Klaus Birkhofer
The PhD Programme ERM offers an integrated approach to current national and international environmental issues helping to improve the quality of professional environmental management for the 21st century. The Programme is a full-time three-year structured programme with 180ECTS awarded, 30 of which are completed in a mandatory curriculum. Upon successful graduation (dissertation, curriculum and defense), the degree of "PhD in Environmental Sciences" is conferred by the Faculty of Environment and Natural Sciences.
Both involved institutes, BTU and UFZ, offer a friendly, productive and international working atmosphere. The involved research units, the Chair of Economics, esp. Environmental Economics at BTU (https://www.b-tu.de/en/chair-of-environmental-economics/team/team/frank-waetzold), and the Department of Ecological Modelling at UFZ (https://www.ufz.de/index.php?en=34213) have strongly interdisciplinary staff and high international reputation in the field of ecological-economic modelling.
The scholarship starting in 2022 will be awarded by the German Academic Exchange Service (DAAD) within the Graduate School Scholarship Programme upon completion of a multi-stage selection process:
1. Applicants submit their complete application to BTU by October 10, 2021 the latest
2. Video-based interview for a selection of short listed candidates conducted by BTU
