Franz-Theo Gottwald teaches environmental, agricultural, food and bioethics. His publications reflect and discuss the following topics: Guidelines for sustainable development in agriculture and food industry, future of animal husbandry, digitalization and sustainable consumption. Paramount among them are questions of food sovereignty and the new field of urban food governance.

In his capacity of honorary professor for environmental ethics at the HU Berlin, he has been doing research and teaching in the master's INRM and Agricultural Economics programs since 2001. He focuses on providing a deeper understanding of environmental and bioethics as well as their fields of application, training and strengthening students’ abilities of argumentation and reflection with regard to ethical questions and the analysis of concrete ethical problems and conflicts arising between the protection and use of soil, plants, animals, humans and future generations.
Since Fall 2021 he does no longer provide a complete module on ethics, but serves as lecturer on the above mentioned topics together with his collegues. He also serves in Bachelor-, Master-Thesis and on Ph.D. level as well as a member of the ethic-commission.
He has been director of the Schweisfurth Foundation for thirty years. The Foundation has been dedicated to ethical ways of doing business, and positive support of sustaining life in viable agriculture and food production methods. Additionally, his leadership, advice and trusteeship have been sought by different associations and organizations, f.e. as chair oft he supervisory board oft he World Future Council.

Jochen Hinkel heads the department of Adaptation and Social Learning at the Global Climate Forum (GCF), which is a transdisciplinary, not-for-profit research Institute founded by nobel laureate Klaus Hasselmann in order to carry out stakeholder-based, solution-oriented climate adaptation & mitigation research. Hinkel also teaches at the Division of Resource Economics at Humboldt University in Berlin. His research focuses on risk management, policy/decision making and governance in face of climate change and associated societal transformations from the following two complementary perspectives:
From a normative/prescriptive perspectives, we apply economic and robust decision theory, together with state-of-the-art climate impact models, in order to co-develop, together with stakeholders, desirable, efficient and robust adaptation strategies.

This operates at all scales, from local city-level case studies (e.g., German Baltic Sea Cities) to continental (e.g., Europe) and global scale analysis (e.g., PROTECT project, Global Coastal Model Intercomparison Project).
From a descriptive and explanatory perspective, we apply frameworks of institutional economics and political sciences in in-depth local case studies in order to gain a deep understanding of what drives institutional and policy change and performance. Current research covers the governance of coastal adaptation in Germany and the Maldives, and project-level funding and financing arrangements for nature-based solution in Europe.
Hinkel has contributed as a Lead Author on coastal risk, adaptation and governance to the last two Assessment Reports of the Intergovernmental Panel of Climate Change (IPCC) and currently co-leads work on coastal decision making in the United Nation's World Climate Research Programme (WCRP).

Jesko Hirschfeld is environmental economist at the Institute for Ecological Economy Research (IÖW) in Berlin since 2002. He is leading and working on research projects in inter- and transdisciplinary contexts that analyse the effects of land use, water management and urban planning decisions on biodiversity and ecosystem services, as well as the challenges climate change poses on environmental planning and sectoral policies. Currently he is coordinating research projects on the effects of urban green and blue infrastructures on regulating and cultural ecosystem services, carrying out extended cost-benefit analy-

ses relying on economic valuation methods to monetarize external environmental effects as well as preferences of stakeholders and the broader public. 2017-2020 he was visiting professor for Environmental and Land Economics at TU Berlin and since January 2022 he is visiting professor for Environmental Economics in the Working Group on Resource Economics at the Albrecht Daniel Thaer-Institute of Agricultural and Horticultural Sciences of the Humboldt-Universität zu Berlin.

The working group Sustainable Land Use in Developing Countries (SusLAND) focusses on the analysis of land use and landscape systems in emerging and developing countries. Based on the analyses, interdisciplinary research methods are used to develop strategies to mitigate complex problems of farming systems in developing countries at local, regional and global scales. Emphasis is placed on questions regarding the avoidance of land use conflicts, the improved adaptation to climate change, food and nutrition security, and the stabilization of the livelihood of family farms. SusLAND operates in Sub-Saharan Africa, Latin America and South Asia and focusses in particular on resource economics in combination with natural sciences.

Foto Ilona Otto Prof. Dr. Ilona M. Otto is a newly appointed Professor in Societal Impacts of Climate Change at the Wegener Center for Climate and Global Change, University of Graz. She leads a new research group focusing on Social Complexity and System Transformation (SoCo). The group’s ambition is to use complex science theory and novel research methods to analyze social dynamic processes and interventions that are likely to spark rapid social changes necessary to radically transform the interactions of human societies with nature and ecosystem services in the next 30 years. Prof. Otto is also interested in environmental inequalities and the socio-metabolic implications of resource and energy, used to support lifestyles of different social groups. She is also an Associated Fellow at the Berlin Workshop in Institutional Analysis of Social-Ecological Systems (WINS) hosted by IRI-THESys Institute at the Humboldt University.
