Urban hybrid dunes in Barcelona

Constructing and maintaining semi-fixed dunes on heavily used urban beaches to optimize the flows of ecosystem services, through collaboration with administrations and stakeholders. Dunes play a central role in coastal defence and protection against sea level rise linked to climatic change. Stakeholder mapping and social research will be used to learn how to shape social attitudes to make the year-round intensive recreational use of beaches compatible with the protection of the dunes.

Green Roof of Aimé Césaire School Complex

Aimé Césaire Primary School: A Garden Home (Source:

In 2013, an experimental and educational project, conceived as a garden home for a school, was built at the heart of the green district known as ‘Duke’s Meadow’ on the Île de Nantes. The building’s roof was covered by 2,700 square meters of natural dunes.

The objective is to create a green roof, relying heavily on a phytosociological approach to plant colonization and high biodiversity, but also a site that is easy to manage.

The originality of its green roof results from a co-construction between architects and landscape designer. Its qualities are undeniable, and this...

ReDuna - Restoration of S. João da Caparica Sand Dunes

ReDuna aerial view

One of the consequences of global warming is the sea level rise. In urban settings along coastlines, rising seas threaten not only houses, but also several types of infrastructures such as industries,  roads, power plants, freshwater aquifers, etc. Rising sea-level also pushes destructive storm surges further inland, posing very high risks for coastal populations, as storm surges can push water kilometers inland, causing extreme flooding far from the coast. 

The Portuguese ReDuna project aims to restore the natural capacity of the Almada sand dune-beach ecosystem to healthily...

Project Coastbusters Biogenic reefs concept


 The public-private Coastbusters consortium aims to study and translate desired coastal protection functionality into designs that make use of the capability of ecosystem engineering species. In other words, does ecosystem creation and Nature-based Solutions’ technical design provide a more sustainable and cost-effective management approach to conventional coastal engineering? To answer this question, two Coastbusters research projects are executed, funded by the Flemish agency for Innovation and entrepreneurship (VLAIO) and co-funded by the industry (Dredging International part of the...
