The FUTURE - a project of 100,000 trees in the Porto Metropolitan Area - is a planned and coordinated effort of various organizations and citizens to create and maintain native urban forests in this region, which needs to enrich its biodiversity, sequester carbon, improve quality of air, protect their soil and contribute to a better quality of life for regional people. The 100,000 Trees Project for the Porto Metropolitan Area” intends to restore 100 hectares of urban forest with native trees. (1, 2)

Nature-based solution

  • Parks and urban forests
  • Large urban parks or forests
  • Green corridors and green belts

Key challenges

  • Climate action for adaptation, resilience and mitigation (SDG 13)
  • Climate change adaptation
  • Climate change mitigation
  • Water management (SDG 6)
  • Stormwater and rainfall management and storage
  • Green space, habitats and biodiversity (SDG 15)
  • Habitat and biodiversity restoration
  • Habitat and biodiversity conservation
  • Green space creation and/or management
  • Environmental quality
  • Air quality improvement
  • Social justice, cohesion and equity (SDG 10)
  • Environmental education
  • Social cohesion
  • Social interaction
  • Health and well-being (SDG 3)
  • Enabling physical activity
  • Creation of opportunities for relaxation and recreation


Creation of new green areas, Maintenance and management of urban nature, Protection of natural ecosystems, Knowledge creation and awareness raising

Project objectives

1. Create and manage a flagship project to reforest the region with native species; 2. Help manage urban forests with the goal of making a difference in the territory; 3. Create training and action opportunities for citizens with the goal of having a positive impact on people’s awareness and practical knowledge about trees and woodlands; 4. Structure a volunteer program for reforestation and management tasks with a goal of contributing to social change and promoting public participation. 5. Also, urban forests filter air, water and sunlight, moderate harsh local climates, cooling the air and slowing wind and stormwater runoff, reduce the urban heat island effect and air pollution, act as carbon sink against climate change, provide recreational opportunities, improve wildlife habitat and biodiversity and create other countless health, social and economic benefits (2)

Implementation activities

By June 2011, after several meeting rounds, the project was able to bring together the basic resources needed for the startup phase: (1) eight planting areas (public and private; in mountain, urban, and riverside areas) totaling around 40 hectares, (2) human resources for planting and management (these forest management teams resulted from the cooperation between landowners associations, the central government and municipalities), (3) indigenous tree seedlings (from state nurseries, through a partnership with a non-governmental organization), and (4) a growing goodwill movement to help with the planting and management (NGO, schools, companies and organizations with social responsibility departments). The main implementation phase of the 100.000 trees project started in September (training) and October 2011 (planting) (2)

Climate-focused activities

Climate change adaptation:

  • Increase or improve urban vegetation cover to help reduce outdoor temperature
  • Create or improve outdoor spaces to help people escape from urban heat

Climate change mitigation:

  • Increase green urban nature for carbon storage (wetlands, tree cover)
  • Improve carbon sequestration through selection of more adaptable species

Biodiversity conservation or restoration-focused activities

Biodiversity conservation:

  • Protect and enhance urban habitats
  • Preserve and strengthen existing habitats and ecosystems
  • Reduce negative impacts and avoid the alteration/damage of ecosystem
  • Protect species
  • Undertake specific measures to protect species
  • Undertake specific measures to protect native species
  • Means for conservation governance
  • Raise public awareness
  • Public engagement
  • Create and use scientific knowledge for conservation
  • Capacity building

Biodiversity restoration:

  • Restore species (native, endangered, or unspecified)
  • Restore native species
  • Public engagement

Main beneficiaries

  • Local government/Municipality
  • Non-government organisation/Civil Society
  • Researchers/University
  • Citizens or community groups
  • Young people and children


Management set-up

  • Co-governance with government and non-government actors

Type of initiating organisation

  • Regional government

Participatory approaches/ community involvement

  • Dissemination of information and education

Details on the roles of the organisations involved in the project

The FUTURO is an initiative of CRE.Porto (Regional Center for Excellence in Education for the Sustainable Development of the Porto Metropolitan Area), coordinated by the Porto Metropolitan Area and the Portuguese Catholic University (Porto). Several public and private entities actively participate in the FUTURE, offering institutional support and material and human resources to the project. There are two main panels working within RCE Porto. The first is a forum for representation of local and regional stakeholders and its main functions are to help outline joint actions and to make a contribution to their implementation. The second key panel is the Coordinating Office which is the engine of RCE Porto. It is committed to making things happen, to prompt collaboration, to managing joint projects, to identifying and preparing funding applications, and to organising meetings between partners. (1, 2)
