Flood protection in the Upper Vistula river basin: grey and green measures implemented in the Sandomierz area

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.

Restoration of the Oka River’s upper estuary, part of the Urdaibai Biosphere Reserve

The estuary of the Oka River is located within the Urdaibai Biosphere Reserve, on the coast of Biscay, Basque Country, north of Spain. It is an area of high ecological value. Its landscape has been transformed over the years by human activities, as it has been inhabited since Prehistoric times. The most important activities affecting the landscape of the estuary have been agriculture, cattle rising and a shipyard. While the first two have practically disappeared, the shipyard activity is still on-going, although with less intensity than in previous decades.

Autonomous adaptation to droughts in an agro-silvo-pastoral system in Alentejo

Herdade do Freixo do Meio is an organic certified farm of 440 hectares located in the Alentejo region in the south of Portugal, a region characterized by the multifunctional agro-silvo-pastoral system of cork and holm oak trees, named montado. This farm employs about 20 people and produces cork, vegetables, fruit, wine and herbs, and holds animals (such as sheep, cows, pig, turkey and chicken) extensively.

Temporary flood water storage in agricultural areas in the Middle Tisza river basin - Hungary

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.

Amphibious housing in Maasbommel, the Netherlands

The Netherlands is a country with a long history of mitigating flood damage and adapting to flood risk. With 60% of the country below sea level, the development and implementation of flood resilient infrastructure has become an important part of the Dutch culture. The flood threat in the Netherlands is not only related to rising sea-levels. Rivers also pose a risk of flooding. This risk is increased by climate change as it causes more frequent and extreme rainfall.

Infrastructure and economic incentives to reduce vulnerability to drought in Segura and Tagus basins

The Segura River Basin in the south east of Spain suffers from a structural condition of water scarcity and drought occurrence. For decades, the focus for dealing with this condition has been placed on instrumental objectives such as increasing water transfer facilities (i.e. Tagus Segura Water Transfer, a major diversion project), developing alternative sources (i.e. desalination and reuse) or making use of water in a more technically efficient way (i.e. irrigation modernization).

Room for the River Regge, Netherlands - restoring dynamics

The Regge River is a typical rain fed river. Starting in the 19th century the first bends were cut and over the years the Regge River was largely turned into a canal. In situations with heavy rainfall, large areas in the valley of the river are flooded. In dry periods, on the contrary, agriculture and the wetlands suffer from the lack of water. Because of climate change, precipitation is projected to become more extreme; showers heavier and dry spells more prolonged. Measures directed at restoring the dynamics of the river must also help to adapt to these projected changes.

 

A transboundary depoldered area for flood protection and nature: Hedwige and Prosper Polders

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.
