IGB statement on the Strategic Environmental Assessment at the Oder River

Scientists critizise scoping document of the Federal Waterways and Shipping Agency
The Concept for the regulation of the Oder River which Germany and Poland agreed on in a bilateral agreement is currently being subjected to a transboundary Strategic Environmental Assessment (SEA) by the German side. The so-called scoping is the first procedural step of the SEA. With the participation of specialised authorities, associations and other stakeholders, the scope of the assessment is planned to be determined. For this purpose, IGB has submitted a research-based statement.

In the meantime, however, a parallel structure has been built in the river to deepen the navigation channel.

The researchers analysed the submitted scoping document from a scientific perspective. In summary, they conclude that neither the project purpose nor the project description clearly emerge from the scoping document. It does not have the technically necessary and objective breadth of analysis, but operates on the basis of preferred assumptions, what influences the result. Also missing is the document with the concretely planned current control concept, which is indispensable for recognising the extent of intervention. The presentation of the project impacts is correspondingly inadequate.

Without providing a complete presentation of the environmental impacts, the scoping document already contains a comprehensive stratification of impact factors, impact areas and objects of protection down to the project level in this preliminary phase, where overall impacts can no longer be measured. In the opinion of the researchers, this proposed early stratification is definitely not sufficient for the assessment of ecological as well as hydrological impacts with regard to professional good practice and should therefore be rejected. They  scientists explain that different stressors can negatively reinforce each other and that all hydromorphological changes and their effects must be recorded at the level of the strategic environmental assessment in the sense of a cumulative consideration in order to be able to meaningfully and comprehensively assess their medium- and long-term effects.

IGB makes the submitted statement available to the interested public.

Already in December 2020, the researchers published an IGB Policy Brief to raise awareness for the dangers to nature and sustainable use posed by the development plans on the Oder River.
