Sustainable development of coastal regions




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...


Mangrove restoration in Costa Rica

A pilot mangrove restoration project in Costa Rica demonstrating how mangrove planting can benefit habitat and species conservation, whilst boosting the local economy. About 40% of Costa Rica’s mangroves were deforested following the collapse of the country’s banana boom in the 1980s. A vigorous fern species has taken over much of the deforested area, preventing the mangroves from re-establishing. A pilot restoration project of 30 ha of mangrove in a protected wetland was implemented, involving clearance of the ubiquitous fern, planting of saplings, and continued fern removal for a few...



NAIAD Case studies: Lez river basin (France)

The Lez river (29 km long) is a small coastal Mediterranean river with a watershed of 746km2. Its spring is the outlet of a large karst aquifer. It then crosses natural and agricultural areas before reaching the plain of Montpellier (with 290 000 inhabitants) and the Mediterranean Sea. The Montpellier plain is characterized by a rapid urbanization with massive land artificialisation and soil-sealing (2920ha decrease of agricultural and natural areas from 1990 to 2012).

The watershed is exposed to a typical Mediterranean weather marked by repeated...



Ecological Restoration & Local Sustainable Fishing by Immersing artificial reefs - PRADO Reefs Project

Artificial reefs - Prado bay (3)

Ecological restoration by immersing diverse artificial reefs to provide shelters and habitats to marine species. The aim of the project is to diversify and regenerate marine natural resources in order to both make local fishing durable and ecological restoration.

  • Protect and provide long term benefits related to biodiversity and then to all the economical activities (fishery, tourism) linked in.

The restoration of the former saltworks in southern France

1 Restore a more natural hydrological functioning that reconnects the surrounding hydrosystems (including the lagoons located further inland, the Mediterranean Sea and the Rhône River).

2 Restore the natural ecosystems characteristic of coastal lagoons and sandy coastlines, including dunes, salt steppes and saltmarshes.

3 Maintain or increase the carrying capacity for breeding colonial water birds.

4 Implement adaptive management to sea-level rise, creating accommodation space for water spread.
