The first LIFE project led by the municipality will make Lisbon greener and “cooler”

Projections of increasing temperatures and decreasing average of annual rainfall over this century make it urgent to adapt cities to climate change.

LIFE LUNGS (acronym for «Towards a more resilient Lisbon UrbaN Green InfraStructure as an adaptation to climate change») is a project that aims to contribute to making the city more resilient to rising temperatures, mitigating the effects of heat waves and water scarcity, which are expected to be more frequent in the near future, being in line with the climate policies adopted by the municipality. The project is implemented between September 2019 and August 2024.

Implementation actions

LIFE LUNGS encompasses 6 implementation actions

Biodiverse rainfed meadows improvement, installation and operation

This action includes the installation, improvement and operation of biodiverse rainfed meadows in areas of Parque Bela Vista and Alto da Ajuda, as a more adapted alternative to climate change than conventional urban lawns. These areas are compatible with grazing of animals (action C2), a solution that is tested for the first time in an area of intensive use.

A flock of sheep as an urban non-mechanic vegetation control and soil conservation agent

This action focuses on the installation of a non-mechanical vegetation control system consisting of a flock of sheep as an alternative to traditional mechanical vegetation control, and also as an integral part of the ecosystem. This flock will be supported by a shepherd, trained to communicate with the population, thus contributing as well to raising awareness and disseminating information.

Water management measures

This action includes a set of sub-actions related to water management measures that allow, through the development of ecosystem services, to deal with water scarcity and intense precipitation events, which are two of the main impacts of climate change in Lisbon.

Increase of tree cover density along Lisbon's urban green infrastructure

Green infrastructure contributes directly to climate adaptation. With the increase in average temperature, according to several studies and scientific forecasts, the effect of urban heat island is a strong threat. Cities will be better adapted, when their green infrastructure is more consolidated. The shade has a concrete action in reducing the surface temperature, and the trees are considered one of the best solutions to combat the effect of the urban heat island.

This action provides for the mass planting of trees and shrubs in various areas of the city, from green spaces to other areas, including streets where they can provide shade directly to buildings and sidewalks.

“Open Desk Office” to foster project replication and transfer in the Lisbon Metropolitan Area

This action includes maximizing the results of the project - in this case, measures to adapt to climate change - in other green urban areas, belonging to CML and other private ones, not directly covered by the project. The larger the green infrastructure area adopting the same type of solutions, the more successful the adaptation to climate change.

Transfer and replication results by stakeholder involvement

European cities and, specifically, southern Europe, face common climate adaptation challenges: rising temperatures, risk of water scarcity or extreme floods. Green infrastructure can act strongly in regulating the climate.

This action aims to guarantee transfer and replication, which are fundamental in a demonstration project, ensuring an international dimension, as it involves the municipality of Málaga (AM) and other national and European stakeholders.
