“Allgäuer Moorallianz” is an initiative which was founded in 2007 aiming to foster moor protection in the Allgäu region. The Allgäu region belongs to the Bavarian Alpine foreland (Germany) and hosts one of the most important hotspots of high wetland with its diversity of moor types existing across the young moraine landscape and at different elevation levels. The conservation of these moor landscapes has a significant effect on reducing climate change impacts and maintain ecosystem services such as climate regulation.

A large restoration project started in 2011 in the former saltworks of Salin-de Giraud, located in the southeast of the Rhône delta, within the Camargue Regional Natural Park and the UNESCO‘s Man and Biosphere Reserve. This site represents a vast coastal area of 6,500 ha in the municipalities of Arles and Saintes-Maries-de-la-Mer, partially transformed and used for industrial salt production from 1950 to 2008. It was characterised by a strong artificialisation, with seafront dykes and disconnection among different water bodies used as ponds for salt extraction.
Pursuant to the Water Framework Directive and in accordance with the environmental objectives of the Hydrological Plan of the Tagus River Hydrographic Basin, in coordination with Patrimonio Nacional (as the entity that manages the Monte de El Pardo area), the improvement of the ecological condition of the river has been proposed as well as the recovery of this space of great environmental value, from the Pardo Reservoir to the confluence with the La Trofa stream (a distance of approximately 6 km).
Amphibians suffer a global decline. This has made them the most threatened group of vertebrates on the planet, with more than a third of the species under some degree of threat. The main threats include the destruction of their habitat, changes in climate, emerging diseases and the disappearance of places of reproduction.
The 19th century industrialisation in Lodz heavily affected the city’s rivers, altering their ecosystems and hydrology. Many rivers in the densely built-up city were canalized. This resulted in a higher flood risk from runoff during heavy rain periods. Low water retention also implies reduction of soil moisture during dry spells, contributing to higher temperature and reduced air humidity (urban heat island). Based on climate change projections, it is expected that the intensity of heavy rain periods and higher temperatures will increase and exacerbate these problems.
The increasing exposure to floods is a consequence of the river regulation and land reclamation works that shaped the landscape in the Tisza River floodplain. During the last 150 years an extensive flood defence and water management infrastructure has been constructed. Climate and land use change in the basin are increasing the frequency and magnitude of floods. The Hungarian Government has been pursuing a new flood defence strategy for the Tisza based on temporary reservoirs where peak flood-water can be released.
Historically, the Regge was a free-flowing shallow lowland river which meandered through a landscape containing marshes, wet meadows and sandy levees. To facilitate shipping, from 1848 onwards the river was straightened by cutting off meanders, and the river channel was deepened and widened. Dams were built to better regulate the river flow, and the floodplain was embanked to protect the adjacent land from flooding. In 1935, the river was almost completely canalised, reducing its length from roughly 70 km to 50 km.
Situated in East Anglia, Norfolk Broads (Broadland) is one of the finest areas of wetland in Britain. It includes both open water, the Broads themselves (a network of mostly navigable rivers and lakes), and the low-lying marshland surrounding the tidal reaches of the Yare, Waveney, Bure rivers and their tributaries. These rivers reach the sea at Great Yarmouth.
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 – low lying areas of reclaimed land are being removed, reopening these areas to the tides.
Stuttgart’s location in a valley basin, its mild climate, low wind speeds, industrial activity and high volume of traffic has made the city highly susceptible to poor air quality. Development on the valley slopes has prevented air from moving through the city, worsening air quality and contributing to the urban heat island effect. A Climate Atlas was developed for the Stuttgart region, presenting the distribution of temperature and cold air flows according to the city’s topography and land use.
