Climate and biodiversity: to a nature positive future

Challenge
There are two traditional approaches to the theme of 'climate and biodiversity'. On the one hand, climate change will have consequences for existing nature and ecological targets. On the other hand, nature can be used to mitigate and adapt to the consequences of climate. It is important to generate and exchange knowledge from both perspectives. But the second point of view receives less attention. For Rijkswaterstaat, this is a missed opportunity, especially in the light of the increasing importance of biodiversity restoration towards a nature positive future.
Conventional infrastructure approaches can often cause negative impacts on other resources and values like nature and biodiversity. We can only tackle Europe’s increased water-related challenges by employing a diverse range of nature based solutions (NbS) from a basic approach and in an integrated way. A hallmark of NbS is that they provide a range of additional benefits to people and nature and thus can help tackle today’s other great global crisis: the loss of biodiversity. In this way NbS can also contribute to the achievement of other international objectives, such as the Sustainable Development Goals and Paris Climate Agreement. Using NbS to address the challenges can also help restore nature across Europe – boosting efforts to achieve other critical policy objectives, including the attainment of good ecological status for all rivers and other waters under the Water Framework Directive. And helping Europe lead the transition to a healthy planet, as outlined in the European Commission’s new Green Deal. 

The discussion will focus on
In this session, Rijkswaterstaat invites you to share experiences in research on the effect of climate change on biodiversity and NbS as a strategy to adapt to the impacts of climate change in large waterbodies. We will share some general concepts and individual cases from our work in large waterbodies. Partners are invited to present their own research. Discussion will focus on best practices, do’s and don’ts, scale, input and output, knowledge questions and sharing information and experiences. 

Goal
The goal of the session is to share good practices and learning experiences in a diverse, multidisciplinary group of academic and governmental experts on water, climate adaptation and biodiversity. We will work towards a knowledge agenda and shared topics for future cooperation and exchange.

Location
The side event will take place at the Blauwe Zaal in Hotel Arsenaal. This is a 1 minute walk from Expo Arsenaal. 

Address: Korte Geer 1, 2611 CA Delft

Walk to Museum Prinsenhof for museum visit, reception and opening dinner

The field visit will  join the group of subtheme 'Extreme River Events'. Our focus is on the change of biodiversity. We will see the use of nature based solutions (NbS) and how this helped restore nature in the Netherlands. We will also look into the possibilities for these solutions in other urbanized deltas across the world. 

We will start our journey upstream the river Rhine, close to the border with Germany, and decent down the river. In Lent the river area along Rhine’s main branch, the Waal, will be visited. Extreme flooding risks here have been mitigated in the Room for the River intervention in this urbanized area, creating new nature and recreation areas. Aspects of River bed erosion and shipping will also be addressed in our visit. In Driel we will visit the weir lock in the Nederrijn as an important object to partially mitigate water scarcity problems in the Netherlands, especially maintaining drinking water reserves in the future. Finally we will visit the “langsdammen” along the Waal, close to Tiel. Here dams have been created parallel to the river in order to reduce erosion, a better groundwater-surface water interaction and improved biodiversity habitats.
