Water as Leverage for Climate Adaptation: Wadden Sea Region Ribe From source to sea Call For Action 1. Understanding the causes and detecting the potentialities In order to give an answer to the many challenges of Ribe, there is a need for a better understanding of the different dynamics behind these challenges, and especially the potential solutions. The different water issues cannot be solved in the center of Ribe itself, but are dependent on the whole water system of the water catchment area. The issue of flooding can probably only be solved when measures are also taken further upstream, and in the landscape on the eastern side, and by intervening in the area between the city and the dyke on the western side. Today, the question lives whether or not a new dyke is needed according to the Risk and Climate Adaptation Plan in development, whether this is the best option and what this means for the possible land use. What if the position of the dyke would be moved more inland towards the city of Ribe? How would this affect the water level balance of the city? What about the landowners of the now flooded land? Could a double dyke system be implemented, creating a new kind of agriculture in this inbetween area? How does this affect the natural values? Next to that, the water level balance of the soil is fragile and there is a need for a better understanding of its conditions and possible solutions, in respect to the heritage value but also in light of being sustainable and futureproof. Moreover, there is a need to improve the conditions for fish passage from the seaside of Ribe through the stems of the river system. This might call for more water on the western part. The city of Ribe has a unique and important historical value that needs to be maintained. However, this asset is under pressure due to the touristic attractivity and the maintaining of the fragile water balance of both soil and river, all this while considering current and future climate dynamics and the impact of new developments. Making the past more sustainable is a very delicate question, which asks for innovative solutions. In short, different scenarios need to be considered on how these multiple threats and challenges could be solved in an integrated way, since they are all dependent on each other. Future investments should be done by bundling forces and by diminishing unwishful effects. Next to the participation of experts to understand the issues better, this asks for the participation of the many local stakeholders in the area: inhabitants, actors of tourism, heritage organizations, farmers, the sportfishing association, inhabitants, industry, the municipality, the wastewater company, Natura2000, and so on. 2. Detecting design principles for a sustainable ‘past’ The possible scenarios for tackling the challenges of Ribe in an integrated way should lead to the 14 Ribe
Setting the Scene for a Call for Action formulation of design principles that are in respect with the local context but which are futureproof and integrated. How can the city be redesigned to maintain the presence and identity of the heritage buildings, while being adaptive for climate change? How can the natural landscape be rethought as a sponge to be more resilient for future flooding and drought? What kind of design principles are needed? How can nature-based solutions help maintain the heritage, while giving it a new attractive face, and help strengthen the wonderful landscape? 3. Integrated plan from source to sea Next to the design principles, there is a need for a plan which looks both to the city of Ribe as well as beyond its borders. The different issues cannot be solved in the city itself but ask for an integrated approach for the whole water catchment area, from source to sea. Which action should be taken where, to give an answer to the different challenges? This asks for an integration of the different wishes of each actor and the various thought-out design principles. That is the contribution that the Water As Leverage trajectory will bring to Ribe, and which will be taken into account within the development of the local Risk and Climate Adaptation that is being developed in the coming years. To do so, the case of Ribe asks for multi-disciplinary teams consisting of experts in: • Hydrology: understanding the water system from source to sea and on the characteristics of the ‘cultural swamp’ in the city centre • Design: thinking out new solutions to combine past and future together • Biodiversity: impact of solutions on the ecosystems, with special attention to birds and fish • Technology: understanding and thinking out new solutions, with a preference for nature-based solutions • Heritage: how to maintain the historical value of the city and landscape? • Juridical matters: understanding the different constellations of land ownership and thinking of new innovative approaches • Participation: how to get everybody on board, with each of the stakeholders having their own mindset, values, and wishes?
