A full consideration of ecosystem services (ES) impacts, interactions and improvements can result in more sustainable and adaptive solutions for dredging and marine construction projects. Furthermore, the benefits can be translated in monetary terms, providing returns on investment and highlighting the links between ecology and economy. For some however, the ES concept is too theoretical. This article seeks to show how the ES concept can actively be applied at any point during a project and the benefits of doing so. Its purpose is to provide a framework for integrated and interdisciplinary thinking throughout the different steps of the project cycle.
To show the success of polymer use in highly contaminated areas, two recent projects are presented: at Port-La-Forêt harbour in La Forêt-Fouesnant, France and at the Kishon River seven kilometres downstream from Haifa, Israel.
The New Suez Canal project was a titanic effort in logistics. Six global dredging contractors completed the works within one year and several records were broken during the execution of the project. The contractors disposed of more than 245 million m3 of sand in just nine months.
A case study of a tidal marsh restoration project at the Polders of Kruibeke in Belgium shows how an Ecosystem Services assessment can reveal otherwise hidden benefits.
As Vietnam seeks a balance between preserving land for agriculture and finding space for industry, creating new land is one solution. But waiting for subsoil to settle naturally at reclamation sites is time-consuming and costly.
A state-of-the-art 3D plume model, used at the Ras Laffan Port Expansion project, simulates alternative disposal scenarios and helps develop Safe Disposal Maps.
