Monsanto Green Corridor integrates Lisbon's ecological structure in a extension of around 2.5 km, with a trails network of around 40km and an area of 51 hectares with thousands of trees and shrubs, gardens and parks, and an agricultural area. It also includes equipment: a children's playground, a skate park, kiosks, cycle paths and viewpoints

The Corridor connects Parque Eduardo VII, in the city center, to Parque Florestal de Monsanto, considered Lisbon “green lung”, with approximately 900 hectares. In addition to green areas, Monsanto has three artificial lakes, a Wastewater Treatment Plant and an Interpretation Center with several environmental awareness activities.

This green corridor, designed in the 70s, was the first and is the most important of the nine corridors that connect important areas of the city and contribute to the fight against climate change and to the implementation of the Lisbon Local Biodiversity Action Plan, whose objective is to increase the performance of biodiversity in the city with the green area occupying 25% of the total area in 2025.

Urban green corridors promote the movement and articulation of historical, cultural and landscape heritage and support different uses compatibility: environmental, sports, aesthetic, cultural and recreational. They are designed for a sustainable city development, because they allow the protection of biodiversity and natural elements, contribute to prevent the formation of heat islands and reduce atmospheric pollution in the city.

The existence of cycle paths promotes sustainable mobility.
In addition to the ecological function, green corridors are socially and culturally very important, they improve people's life quality through physical activity and mental relaxation, promote tourism with positive effects on the city's economy and promote population cultural  by allowing access, for example, to outdoor amphitheaters.

Direct SDGs:

• SDG 11 Sustainable cities and communities: Reduction of the city's adverse environmental impact; universal access to public green and safe spaces, inclusive and accessible.
• SDG 13 Climate Action: Improve education, awareness-raising and human and institutional capacity on climate change mitigation, adaptation, impact reduction and early warning
• SDG 15 Life on Land: Prevention of biodiversity threats; sustainable use of terrestrial ecosystems.
   

1. What is the Lisbon Local Biodiversity Action Plan objective?
2. How do green corridors contribute to sustainable city development?
3. How do green corridors contribute cultural and socially?
    

The green corridors gives a possible new life to the city's animals through the construction of habitats and the establishment of connections between habitat areas, and, consequently, the movement of species, matter and energy. The city also benefits from dust settling, wind protection and breeze regulation. Additionally, the green corridors: i) allows the regulation of thermal amplitudes and atmospheric luminosity; ii) is particularly effective in lowering water and air temperatures due to shade and high evapotranspiration; iii) positively interferes with hydrological processes, reducing risks of erosion: iv) and allows the circulation and infiltration of rainwater in the open air, promoting the use of water.
