Sabrina Kirschke is a Senior Research Associate at UNU-FLORES. She contributes to the research, academic, and capacity development activities in water resources management within the resource nexus. Before joining UNU-FLORES, she worked as a research associate in several water-related projects at the Helmholtz-Centre for Environmental Research (UFZ) in Magdeburg, Germany and as a consultant and intern at the Deutsche Gesellschaft für Technische Zusammenarbeit und Entwicklung GmbH in Eschborn and Uganda. She is particularly interested in conceptualising complexities of water quality-related nexus problems and to developing governance strategies to addressing these problems in practice. Her work refers to various regional levels (e.g., transboundary, national, local) and regulations (e.g., European Water Framework Directive). She is experienced with interdisciplinary and problem-oriented research, in-depth cooperation with stakeholders, and the application of qualitative and quantitative research methods. During her PhD, she worked on the role of complexity in addressing the water quality challenge.

Wolfgang Wende is a landscape planner, who studied at the Technical University Berlin (TUB) Germany. After he graduated with a Diploma of Planning Engineering he followed an awarded doctorate fellowship of the State of Berlin for young scientists analyzing the effectiveness of the German Environmental Impact Assessment system. In between the years 1999 – 2006 he worked as a scientific assistant at the Department for Landscape Planning and Environmental Impact Assessment TUB. 2006 – 2008 he was announced as a visiting professor at TU Berlin. His additional research from that time up to today was strongly focusing on the German and on international biodiversity and ecoystem services Mitigation Regulation Systems (IMR), thus, biodiversity offsets and habitat banking. His book ‚Biodiversity Offsets‘ is receiving worldwide attention:

2008 – 2009 he changed his position to the Federal Environment Agency Germany, Dept. of Spatial and Environmental Planning.

Since 2010 he is a professor for urban development at the Technische Universität Dresden and head of Research Area Landscape, Ecosystems and Biodiversity at the IOER Dresden. He also has broad European wide and international experience, e.g. being visiting professor at the NUS (National University of Singapore) for landscape policies (from 2009 - 2021).

From 2011 until 2016 Wolfgang has been President of the German Environmental Impact Assessment Association promoting and supporting environmental impact assessment and new biodiversity offset approaches emerging in Europe and all over the world.


Katharina Stein studied biology with special emphasis on tropical ecology. Her PhD focused on basic research in the Atlantic Coastal Rainforest of Brazil on the pollination ecology of endemic plants. As a post-doc she focused on applied ecology in West-African socio-ecological systems. Her research areas comprise biodiversity assessment and valuation of ecosystem services, nature conservation and natural resource management, bee pollination ecology, crop production and human livelihood, functioning of tropical ecosystems (in West Africa, South America), and socio-ecological systems under global change.

Katharina is also member of the IUCN Wild Bee Specialist Groups on best practice and policy and currently working as scientific associate at the Centre for International Postgraduate Studies on Environmental Management for professionals from developing countries. She is active in lecturing, publishing and supervising students in an international setting also in the global South.

Scientific Experts

Dr Floor Brouwer

Adjunct Professor, UNU-FLORES, Germany

Dr Patrick O’Farrell

Adjunct Researcher, UNU-FLORES, Germany

Dr Martina Artmann

Head of the Leibniz-Junior Research Group: Urban human-nature resonance for sustainability transformation (URBNANCE), IOER, Germany

Floor Brouwer is an Adjunct Professor at UNU-FLORES, working primarily on the conceptual advancement of the Resource Nexus. He is an environmental economist working on the integrated management of natural resources. His focus on the conceptual advancement of the Resource Nexus includes targeted Resource Nexus studies (e.g., on the agri-food nexus), education, capacity development, and quality assurance. He was formerly a scientific coordinator of an EU-funded project on the sustainable and integrated management of the nexus (SIM4NEXUS). He is also leading the Nexus Project Cluster, a group of 30 independent Water-Energy-Food cross-sector research initiatives who team up for increased and more impactful communication and dissemination of the Nexus.

I have 20 years of applied research and project experience focussed on the role of nature in development. My work focuses on understanding social-ecological systems within a development and conservation context. I have explored the area of ecosystem services from diverse perspectives and have worked on the measurement, quantification, modelling, and spatial mapping of services flows of the associated ecological processes, and sought to establish the values that people attribute to these within in variety of landscapes. This work has provided support to local, national and international decision-makers and managers.

Martina Artmann completed a Bachelor's degree program in Agricultural Science at the University of Hohenheim (Germany) and received her M.Sc. degree in Landscape, Regional and Urban Management at the University of Salzburg (Aus-tria). In 2015, she obtained her doctor’s degree at the Department of Geography and Geology of the University of Salzburg (Austria). Her dissertation was about efficient urban soil sealing management. Since 2015 she is researcher at the Leib-niz Institute of Ecological Urban and Regional Development (IOER), Dresden (Germany) leading since 2020 the Leibniz-Junior Research Group ”Urban human-nature resonance for sustainability transformation” (URBNANCE). In her recent studies, Dr. Artmann is linking urban ecology with sustainability transformation. In this regard, she is researching on edible cities as an approach for linking urban residents with nonhuman nature and food. Looking for leverage points for sustainability urban transformation, she is currently working with her research group on the concept of urban human-nature resonance addressing vari-ous relational discourses of sustainability science such as deep ecology, indige-nous knowledge and relational values. Besides, Dr. Artmann is board member of the Society for Urban Ecology (SURE).
