Abstract:
Exploring strategies for sustainable management requires an integrated, scientific and problemoriented
approach involving a combination of environmental and socio-economic aspects in view of
the manifold issues and often conflicting stakeholder interests which have to be addressed. It calls for
more interdisciplinarity in science, translational research (see below) and transdisciplinarity in form
of a science-practitioners dialogue and interaction. There are constraints to crossing interdisciplinary
boundaries in science. By tradition, scientists are usually confined to specialized niches of knowledge
and are not easily prepared to embark on interdisciplinary endeavors. Interdisciplinarity, even among
natural sciences, requires new research approaches and new ways of thinking. The challenges
become even more formidable when bridging natural and social sciences, e.g. when connecting
abiotic framework conditions with environmental processes and social and socio-economic aspects.
Translational research – oriented towards defining ways to communicate with practitioners and
introducing research findings into political decisions – requires new and diverse formats of
education, training and networking.
I use examples of personal engagement in water issues over the last 30 years to outline the challenges
of getting involved in applied research and science-policy interactions. The first two examples refer to
a long-term engagement in resource-management in SE-Asian reservoirs and lakes. Following an
early ecosystem-oriented study on the Parakrama Samudra reservoir in Sri Lanka (1979-1982), a
multidisciplinary EU-program was launched. The international project, carried out by a consortium
of Asian and European scientists, provided a large amount of factual information (Schiemer et al.
2008) and a wealth of experience regarding the challenges of formulating a system-oriented approach
comprising environmental and socio-economic aspects and transferring the scientific knowledge into
real-world politics.
The second set of experience refers to the management of the riverine landscape of the Danube in
Austria. Large rivers with their extensive wetlands and floodplains offer a wide variety of ecological
services, e.g. flood retention, drinking water supply, fisheries and conservation. Other human uses are hydropower production and navigation. They represent partially conflicting stakeholder interests of
different political power. Human impacts over the past 150 years through river regulation, damming
and pollution have reduced some of the service capacities and call for rehabilitation measures. In
1983/84, I became engaged in a major public discussion over a projected hydropower dam. As a
result of the critical position taken by scientists, we were invited by the government to take part in a
commission of practitioners, planners and scientists to develop long-term management and
restoration concepts. The panel was requested to find science-based compromises for conflicting
stakeholder interests. This engagement forced scientists of various disciplines – ecologists,
hydrologists and geo-morphologists – to develop a common understanding of the vulnerability of
river-floodplain systems to human interventions. Over the past thirty years, scientists played a
significant role in this discussion process, defining environmental targets and developing
benchmarking and assessment criteria for management options. This involvement was also a school of
learning regarding interaction with stakeholders and decision makers.
