Successful final conference of the SALTSA project

On September 17th, 2021 the final conference of the project "SALTSA: Groundwater salinization by rising sea levels as a social challenge - the example of Northwest Germany" took place. SALTSA is an inter- and transdisciplinary project in which a synthesis of social perceptions and challenges with hydrogeological modeling was carried out. In addition, 15 experts from 14 institutions and authorities involved in water management were involved in the project.

The focus of the event was the presentation of the project results. For example, it was shown that the perception and awareness of the problem of groundwater salinization and the processes that caused it has increased among most of the participating actors during the course of the project. The results of the hydrogeological modeling suggest that the rise in sea level and the change in drainage levels in particular will have a strong impact on the future situation of salinization. Future issues mainly relate to modern, dynamic and holistic water management.

The conference was rounded off by two further program items. Gualbert Oude Essink, Dutch expert on groundwater systems (Deltares), gave a keynote on the topic “Supporting decisions on strategic water management issues of stakeholders using modeling tools: on some dutch cases”. In addition to vivid examples from the work of Deltares, a national Dutch institute with the aim of effective and timely climate change adaptation and direct integration into the national political system, he presented models and possible adaptation strategies for the Dutch region of Zeeland with regard to groundwater salinization. The conference ended with a lively panel discussion. Uwe Sütering (OOWV), Jörg Elbracht (LBEG) and Godehard Hennies (Wasserverbandstag) gave keynote speeches on the subject of “Groundwater salinization at the North Sea coast - what is the current status? What are the needs regarding knowledge and action?".

The SALTSA final conference took place in a corona-compliant hybrid format. The actors who worked closely with the project team over the course of the project were invited to be present. At the same time, the conference was broadcast digitally and 38 interested listeners from science and practice took part online.

Publication of Adaptiveness: Changing Earth System Governance as part of the Earth System Governance Project Series

Adaptiveness is edited by Riyanti Djalante and Prof. Dr. Bernd Siebenhüner. Dr. Nicolas Jager and Julie King are contributing authors.

Rapid and transformational actions are more urgently needed than ever to achieve a just, resilient, and ecologically sustainable global society, as envisioned and supported by the Sustainable Development Goals. Dynamic governance approaches are vital for addressing changing and uncertain conditions. At many levels, governance needs to be responsive and flexible - in one word - adaptive.
This book provides a state-of-the-art review of the conceptual development of adaptiveness as a key concept in the environmental governance literature, complemented by applications from global, regional, and national levels. It reviews the politics of adaptiveness, investigates which governance processes foster adaptiveness, and discusses how, when and why adaptiveness influences the governance of diverse systems. It is a timely synthesis for students, researchers and practitioners interested in environmental governance, sustainability and social change processes.
This is one of a series of publications associated with the Earth System Governance Project. For more publications, see

Project launch of "WAKOS - Water at the coast of East Frisia: basis for tailor-made climate services for adaptation"

After the launch of the project Gute Küste Niedersachsen on January 01 2020, the joint project WAKOS started on June 01 2020. Thereby, we are happy to welcome two new research fellows and PhD students in our team - Evke Schulte Güstenberg, working in the project Gute Küste, and Annalena Schoppe, who is engaged in the project WAKOS.

The focus in the WAKOS project is on the preparation of regional climate data or rather climate scenarios, which ought to be used as a basis for the discussion about the socially accepted need for action in coastal protection. The new joint project will be executed in collaboration of the Helmholtz-Zentrums Geesthacht (HZG), the NLWKN – research unit Coast, the University of Hamburg, the Jade University of Applied Sciences Wilhelmshaven / Oldenburg / Elsfleth and the Carl von Ossietzky-University Oldenburg. The project is funded with 2.29 million euro by the Federal Ministery of Education and Research. The subproject, managed by Dr. Leena Karrasch and Prof. Dr. Bernd Siebenhüner, concentrates on the identification of concepts for elicitation of regional capacity and necessity for adaptation, which is applicable in the model region and is socially accepted, to finally strengthen the resilience of the model region.

IPCC picks up article by Dr. Leena Kararsch

In the IPCC Special Report on the ocean and cryosphere in a changing climate, which deals in particular with the impacts of climate change on low-lying islands, marine ecosystems, coasts and communities as well as risk management and adaptation, research of the University of Oldenburg gets a hearing. In the chapter 'Integrative Cross-Chapter Box on Low-lying Islands and Coasts', an article by Dr. Leena Karrasch, Martin Maier, Michael Kleyer and Thomas Klenke is cited.

A significant role to include society in the development of future adaptation measures in low-lying coastal areas play participatory processes, collective landscaping and a co-design of ecosystem-based management, as examples at the North Sea coast show (Karrasch et al. 2017, S. 666).

Project „Gamification of Interdisciplinary Higher Education“ approved

As part of the University package 2020 and the tender "Innovative teaching and learning concept: innovation plus", the project „Gamification of Interdisciplinary Higher Education“ by Dr. Thomas Klenke, Dr. Leena Karrasch and Malena Ripken is approved with 48,800€. Aim of the project is to develop the module 'Planning and Management of Coastal Zones and Sea Basins” with the approach Serious Gaming. The main objectives are (1) to develop concepts for the implementation and improvement of the game-based teaching content, (2) to use and reflect Serious Gaming continuously in the further course of the module, (3) incorporate external international guest lecturers and practice partners, as well as (4) to carry out a problem- and research-based and self-directed learning, to create the base for decision making for sustainable development in coastal areas and European seas.

New research project: Gute Küste Niedersachsen

Great success for the consortium of the Universities of Hannover, Oldenburg and Braunschweig

Ecosystem-strengthening coastal protection at the coast of Lower Saxony: that is topic of a new research alliance of the Leibniz University Hannover, the Carl von Ossietzky University Oldenburg and the Technische University Braunschweig. The network is financed with 2.5 million € by the Niedersächisches Vorab of the Volkswagen Foundation.  In field tests, the research institutes develop and test methodologically action and management possibilities for an ecosystem strengthening coastal protection together with local actors. One part of the project is managed by Dr. Leena Karrasch and Prof. Dr. Bernd Siebenhüner.

Notification on presentations by Prof. Dr. Bern Siebenhüner about the subject of 'Research and Climate crisis'

In December, Prof. Dr. Bernd Siebenhüner will speak at two events about the climate crisis.

At December 12 2019, an event about internationalisation and sustainability takes place in the foyer of A14. Mr Siebenhüner will discuss the following questions with Prof. Dr. Hans Gerd Nothwang (Fc VI), Prof. Dr. Joachim Peinke (Fc V) and Prof. Dr. Gabriele Gerlach (Fc V):

  • What consequences has internationalisation for the environment?
  • What can the university and each individual do to reduce CO2 emissions, e.g. at business trips?
  • What support do we expect from politics?

On December 09 2012, an evening event takes place at the BIS-room about Fake Science? - Why we can trust the IPCC and how climate research about the interdependence of atmosphere and ocean works. With his input, Bernd Siebenhüner explains the emergence of the reports published by the IPCC and its political relevance. Oliver Wurl will be connected live from the research vessel "Falkor" from the Pacific, on which he examines the correlation of oceans and the atmosphere at the example of the Pacific Ocean. In this connection, he explains the practical procedures of his work. The event starts at 7:30 pm.

Both events are organised in the context of Scientists for Future.

BREsilient Workshop series

On November 07 2019, the first of three workshops of the series about flood provision in the Pauliner marshlands of the project BREsilient took place.

As areas for local recreation, for athletic activities and as a home for associations, the Pauliner marshlands and the allotment garden area "Im Suhrfelde" are of high importance for the people on-site and beyond that. The attractive location close to the Weser arranges a special appeal but also hides risks. Heavy rainfalls and storm surges at the North Sea or snow melting upstream can cause extensive floodings in this area. This is the reason why the whole area is identified as a flood area. In a three-part workshop series, citizens, associations and actor of local politics and administration are supposed to develop adaptation measures for the preventions of flooding for the Pauliner marshlands and "Im Suhrfelde". The first Workshop "Flood prevention: analyses and discussion on adaptation measures" took place on November 07 from 5-8 pm at the Bürgerhaus Weserterassen.
