Sources: 2. Developments: 2. Greenpeace issued reports warning of accelerating coastal erosion and sea-level rise affecting the Atlantic coastlines of Portugal and the Canary Islands. In the Canary Islands, the organization noted that nearly four kilometres of shoreline disappear annually, threatening 150 km of coast and exposing 72% of wastewater discharges. In Portugal, estimates suggest 40% of beaches could vanish by 2100, with over 100,000 residents living in flood-prone zones. Following these environmental concerns, the Government of the Canary Islands approved an update to its Special Plan for Civil Protection and Emergency Response to Flood Risk (PEINCA). This revision modified the identification of significant potential flood risk areas, resulting in the removal of nine coastal risk areas across Gran Canaria, Lanzarote, and Tenerife. The Minister of Territorial Policy, Cohesion, and Water, Manuel Miranda, stated the update ensures civil protection efforts are coordinated with current hydrological risk management plans. ## Timeline ### 2026-08-31: Canary Islands updates flood emergency protection plan The Canary Islands government has updated its flood emergency plan (PEINCA), removing nine coastal areas from the significant flood risk list to better align with current hydrological data. 2 sources. https://clstr.news/cluster/canary-islands-updates-flood-emergency-protection-plan ### 2026-08-05: Greenpeace warns of accelerating coastal erosion in Canary Islands and Portugal Greenpeace warns that rising seas are eroding coastlines in the Canary Islands and Portugal, urging emergency protection plans and a halt to high‑impact development. 2 sources. https://clstr.news/cluster/greenpeace-warns-of-accelerating-coastal-erosion-in-canary-islands-and-portugal --- Cite as: Coastal erosion and flood risk in Canary Islands.
