The islands of Macaronesia are not spared from the effects of climate change, being very vulnerable to their consequences given their particular geographical situation, insularity, remoteness from the continent, fragmentation, external dependency, scarcity of natural resources, demographic density, dependence on the tourism sector and great biodiversity.

The Hedwige-Prosper polders project is part of the Belgian Sigma Plan: this integrated plan is reinforcing dikes and quay walls and opening flood areas to protect land along the Scheldt Estuary and the upstream basin against floods. In this specific project, the outer defences of the Hertogin-Hedwige (hereinafter referred to as Hedwige) and the Prosper polders â€“ low lying areas of reclaimed land are being removed, reopening these areas to the tides.
The Albert canal in the eastern part of Flanders connects the industrial zones around Liege with the harbour of Antwerp. Ships can continue their way at both ends of the canal: via the river Scheldt to the Netherlands and via the river Meuse to France. In the future the Meuse basin, from which the Albert canal receives its water, is projected to experience more and longer periods of low river discharge, as a consequence of climate change, and so less water is expected to be available for sluicing ships. This would limit inland navigation.
In 2000, the governments of Bulgaria, Romania, Ukraine and Moldova pledged to work together â€“ with the signing of the Lower Danube Green Corridor Agreement - to establish a green corridor along the entire length of the Lower Danube River (~1,000 km). All partners recognized a need and shared responsibility to protect and manage the Lower Danube in a sustainable way.
