    The title of speech

    Dutch policy and practice in NBs & governance aspects of implementing NBs

    Short abstract of speech

    Nature-based solutions (NBS) can play a critical role in improving water security, including mitigation and adaptation to climate change. The Netherlands has a long history of using NBS to manage water resources, and these solutions have proven to be effective in reducing flooding, improving water quality, and providing other benefits. Given that the Netherlands is a global leader in the development and use of nature-based solutions (NBS), the policy and practice of NBS in the Netherlands will be shared in the speech.

    The title of speech

    NBS to enhance urban resilience

    Short abstract of speech

    Urban water systems are essential to a city's infrastructure, playing a pivotal role in supporting the economy, health, food supply, and natural ecosystems. Clean and readily available water is the backbone of these systems. It's crucial that our infrastructure is designed not only for today's needs but also to meet future challenges. Nature-based solutions (NBS), including green infrastructure, are instrumental in fortifying urban resilience. They offer a myriad of benefits, from flood risk reduction and water quality improvement to biodiversity enhancement and the creation of sustainable urban ecosystems. Moreover, these solutions can serve dual purposes, such as providing recreational spaces that enrich local communities. 

    Deltares is at the forefront of NBS research, spanning various scales. Our studies range from field tests on permeable pavements and bioswales to experiments with mangroves and willow trees for coastal defense, and investigations into storage and retention in river systems. We will present our climate resilient city toolbox.

    The title of speech

    Enablers for developing NBS – experiences from EcoShape, Building with Nature

    Short abstract of speech

    Based on the combined climate and biodiversity crises, the interest in Nature-based Solutions (NbS) is rising worldwide and the need for infrastructure development using NbS instead of traditional solutions is generally acknowledged.

    However, still many investments in infrastructure whether for climate adaptation or in general are not developed in a nature-inclusive let alone nature-based approach. EcoShape, a consortium established in the Netherlands in 2007 has developed its Building with Nature (BwN) knowledge programs to address the necessary paradigm shifts to enable the development of NbS. Via a learning-by-doing approach, various pilots have been initiated, developed, designed, constructed, monitored and evaluated in one of the three programs that EcoShape has conducted. Most of lessons learned are capture in the six Enablers for BwN that EcoShape has derived; these six Enablers need to be met to overcome the barriers that are preventive of NbS development. For each of them, EcoShape has advices based on scientific knowledge and practical experiences in the field to help progress NbS.

    During the speech these Enablers will be discussed and the main advices on working with them will be presented using the various in-field cases that EcoShape has conducted.

    Stream restoration as guided by the NbS criteria

    Short abstract of speech

    Although the natural solution is a new slogan that has emerged in recent years, it is based on the long-standing desire of humans and nature to coexist harmoniously.

    The author analyzes the 8 criteria set by IUCN for natural solutions and uses examples to illustrate how these criteria guide river restoration and promote paradigm shift.
