Climate change impacts

Rise in the average level of seawater - increase in the average sea level between 0.17m and 0.38m for 2050, and between 0.26m and 0.82m by the end of the twenty-first century; other studies project an increase to 1.10m in 2100 in the most extreme scenery (global projections). Increased likelihood of floods and flooding - increased likelihood of flash floods throughout the twenty-first century due to the increased intensity of rainfall will occur over shorter periods. Excessive rainfall and strong wind - decrease in episodes of rain and strong wind, however, these will be gradually more intense in the winter months; increased intensity of rainfall coupled with more intense winter storms, accompanied by rain and strong wind; decreased seasonal rainfall but more precipitation in the winter months (up + 10%) and a decrease in the rest of the year, especially in spring (up to -52%); decreased of annual rainfall (up to 15 days); drought appearance. Increase in the annual average temperature, especially the maximum - rise in annual average temperature between 1 ° C to 5 ° C; significant increase in the spring, summer and autumn (up to 5 ° C); more frequent heat waves (four times in 2041 to 2070 and from 2071 to 2100 quintuples compared to the current climate).

Main motivation for taking adaptation action

The results obtained via Barreiro's "Municipal Risk Mapping" emphasise the importance of identifying the current climate vulnerability of the municipality, justifying the need to draw up a strategy for adaptation to climate change, as well as a long-term prevention and mitigation perspective.

Adaptation strategy

Have you already developed an adaptation strategy?
Yes, we have an adaptation strategy
Name of the strategy/ plan (If adopted)
Municipal Strategy for Adaptation to Climate Change “Estratégia Municipal de Adaptação às Alterações Climáticas” (EMAAC)
Date of strategy/plan approval
Sep 21, 2016
Summary of the strategy/plan
The Municipal Strategy for Adaptation to Climate Change (EMAAC) for the city of Barreiro allowed us to identify current and future vulnerabilities and find options for adaptation to climate change for the municipality. We identified 20 adaptation measures that allow us to minimize the risks from rising sea levels as well as excessive rainfall associated with floods and heat waves. This strategy identified the actions that the council needs to take to mitigate the impacts of climate change. The adaptation strategy for the municipality of Barreiro, follows the "Municipal Risk Mapping," which has been approved by the National Civil Protection Authority and is also related to climate change adaptation. The document is also linked to the Master Plan currently under review and includes the identification, characterization and methodical evaluation of natural, mixed and technological risks. As a result, a detailed compendium of the main risks that helped in the creation of an effective adaptation strategy. It also supports the work of civil protection in the city, improving planning and reducing risks. This risk mapping promotes a territorial organization model, creating the basis for a municipal geographic information system, as defined in the "Legal Framework of Land Management Instruments". This model aims to: 1) identify constraints, reserves and protected areas for the permanent realization of civil protection plans; and 2) create the performance conditions in critical areas. This model should establish a preventive system of risk management that includes planning and land management.
Additional information on adaptation responses
The Municipal Civil Protection Service contributed to the city's adaptation-related activities by sharing information that formed the basis of preparing the "Municipal Emergency Plan" and "Plan of External Emergency". Their role and the process followed included: 1) informing of all measures, programs, plans, policies and civil protection operations; promoting information sharing; conducting training and awareness raising among the population. 2) Conducting a survey regarding the assessment and prevention of collective risks; permanently analyzing the municipality's vulnerabilities, proceeding to the dissemination of appropriate forms of building protection, maintenance of cultural and heritage assets, facilities, essential services and natural resources. 3) Coordinating and monitoring training and simulations developed in the field of civil protection and providing an opinion on the fire safety risks in licensing procedures for private works.

Good practice / spotlight item

Retention basins for flood prevention
Barreiro experiences flooding caused by heavy rains, undersized infrastructure drainage systems, and the obstruction of water lines. As a way to address cyclical flooding caused by heavy rainfall, Barreiro conducted a hydraulic study that led to the "stormwater retention basins" project. The aim is that the retention basins retain water and increase the time flow.
