Subjects and hosts of the in-depth sessions

1 Land of sand. Land of mud. Reclaiming new landscapes

Hosts: Rik de Visser (Bureau Vista) and Laura Cipriani (TU Delft)

This session intends to claim the ‘necessity of landscape’ in land reclamation processes. The session includes two parts. The first part intends to collect, present, and analyze a series of reclamation projects on a global scale, emphasizing landscape, urban, environmental, and social conflicts in artificial lands worldwide. The second part intends to present how the landscape architecture approach became an element of success and innovation in constructing the Marker Wadden project: a new archipelago that consists of marshland and shallow waters designed to attract an abundance of birdlife.

2 Marker Wadden as example for other areas (upscaling and financing)

Hosts: Fokko van der Goot  (Boskalis/EcoShape) and Stefan Aarninkhof (TU Delft/EcoShape)

3 Beneficial Use of  Sediments: enablers and practical guidelines

Hosts: Thomas Vijverberg (Boskalis) and Thijs van Kessel (Deltares)

This session deals with the beneficial use of sediments, focusing on the use of fine sediment fractions that are traditionally considered as being less suitable for beneficial use. Experiences from ‘Marker Wadden’ and ‘kleirijperij’ demonstrate that beneficial use is possible, but that this is only feasible if variability and uncertainty in sediment properties is well monitored, or adaptive building methods are used. Based on these experiences a set of practical guidelines has been derived and will be discussed in the workshop, with special attention to control and intervention methods. Main enablers and distractors for future projects will also be discussed.

4 Role of climate adaptation in Nature Based Solutions

Hosts: Piet Dircke (Arcadis) and Bregje van Wesenbeeck (Deltares)

Recently nature-based solutions that work with natural processes and ecosystem services, are gaining popularity to adapt to climate change. NbS are considered to provide multiple benefits, such as contribute to mitigation of and adaptation to climate change. In addition, they can function in an adaptative manner under changing external pressures, for example by accreting sediment under sea level rise. However, several elements are also unknown with respect to NbS. This workshop aims to map opportunities for NbS upscaling and mainstreaming and to create a battle plan on how to approach that.

5 Ecosystem Restoration; an effective measure for biodiversity recovery?

Hosts: Liesbeth Bakker (NIOO)

6 Role of climate mitigation in Nature Based Solutions

Hosts: Piet Dircke (Arcadis) and Bregje van Wesenbeeck (Deltares)
