As a Mediterranean coastal city, Barcelona is particularly vulnerable to climate change. Its high population density also magnifies the local heat island effect which causes an array of health and environmental challenges. Climate change projections include a rise in average temperature and a significant decrease in rainfall, with expected lasting droughts and intense heat waves. In response, Barcelona has committed to becoming a global model of a sustainable city combating urban development challenges related to climate change and population density.

Forests can provide effective protection against rockfalls, landslides and avalanches; their preservation and proper management can maintain these services and functions which assume relevance also in the perspective of adaptation to current extreme events and future climate changes. The Protect Bio method enables the evaluation of these ecosystem services. The method aims to evaluate if technical protective (and expensive) measures (i.e.

The Vistula River is a 1,046 km long river which springs in southern Poland and ends in the Baltic Sea. The Upper Vistula extends over the three Polish provinces of Małopolskie, Podkarpackie and Swietokrzyskie. The Upper Vistula region covers an area of 43,000 km², including the cities of Krakow, Tarnow, Kielce, Nowy Sacz, Rzeszow, Przemysl and Krosno. The area is also known for its extraordinary natural values. The region is prone to flood risk both in winter and in summer.

The Forested Infiltration Area (FIA) is proving to be an effective tool in Northern Italy helping to address water scarcity challenges and/or to achieve environmental benefits over the long term. FIA is a method to recharge groundwater aquifers by channelling surface waters during times of excess into designated areas that have been planted with various species of trees and/or shrubs.

“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).

The 19^th 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.
