What is the Ebro Delta?

In its final segment, the Ebro river makes up the second largest delta in the Western Mediterranean in terms of area, with an emerged surface of some 320 km2.

It is the most significant natural environment on the Catalan coast.

Climate projections

The Ebro Delta is an area extremely vulnerable to the impacts of climate change and poor management of the river basin, both in terms of the contribution of water flows and sediments.

The lack of water flow and sediments

Water flow and annual water contribution from the Ebro river show a significant decrease –near 30%- when comparing figures from before the Tortosa plant began operating (1912-2013) with those from after the large dams were built throughout the river basin (1980-2013).

The lack of water flow and sediments

The retention of sediment by dams and reservoirs in the Ebro basin causes the coastline to recede and speeds up the sinking of the deltaic marshes.

The challenges and the solutions

The main challenges identified in the Ebro Delta are agreement and consensus on the solutions to be carried out.

The main solutions to climate change and to the poor management of the Basin must be based on the contribution of flows and sediments (Nature-based Solutions)

The Secretariat for the Environment and Sustainability, in collaboration with the Platform for the Defense of the Ebro river, is promoting this exhibition which aims to show the impact of climate change on the evolution of one of the richest in biodiversity and, at the same time, most vulnerable deltaic systems in Europe: The Ebro Delta.
