Leren van vijf jaar samenwerken in het programma ED2050

Ecologisch herstel, Eems-estuarium, adaptief, samenwerking

Na vijf jaar uitvoering van het programma Eems-Dollard 2050 maken we in dit artikel de balans op. Welke lessen zijn er geleerd? Hoe kijken we terug op de gekozen aanpak? Welke oplossingsrichtingen komen (en blijven) in beeld om het herstel van het estuarium daadwerkelijk dichterbij te brengen? Is de manier van samenwerken aan herziening toe? Wat vragen de nieuwe uitdagingenvan ons? Spoiler alert: de volgende periode van vijf jaar wordt geen kopie van de eerste; ED2050 blijft immers een adaptief programma.

Working on ecology in the Ems estuary in perspective. Learning from five years of cooperation.

Ecological restoration, Ems estuary, adaptive, cooperation

In 2016 national and regional governmental authorities started the adaptive program for ecological restoration of the Ems estuary in cooperation with the harbour authority, industry and environmental NGO’s (ED2050). The co-operation is based on the understanding that a vital and resilient ecosystem also forms the foundation for economic development. The program aims at solving long term problems, such as high silt concentrations, habitat impoverishment and subsequent decrease in biodiversity.

The program is working along different strategies: knowledge development about the hydro-morphology,
habitat development along the coastline and useful application of silt. Extraction of silt helps to reduce the excessive turbidity of the estuary when applied at a scale of least 1 million ton per year. Also transboundary co-operation with Germany is part of the strategies. We present nine strategies to follow up the lessons learned in the first period. For example, we learned, that we also have to take the effects of sea level rise into consideration and we conclude that some of the solutions have to be found in the inland areas. This emphasizes the need for an integrated, spatial approach. Synergy may be found with inland measures for climate-adaptation and recreation. For measures in the estuary itself co-operation with Germany is essential.
