The most common ways of financing the implementation of nature-based measures are:
- the municipal budget (general);
- municipal budget, decided on through participatory budget voting;
- European funds (mostly structural and cohesion funds 2007-2013);
- Lisbon´s Casino direct funding obligations;
- partnerships with private companies resulting from municipal taxation and charges for permission to use public space during occasional events or as direct compensation from services that require municipal authorisation;
- sponsorship from national and private companies.
Success and limiting factors
The urban regeneration measures taken so far have shown how the restoration of Lisbon’s historical quarters and its riverfront, using nature-based solutions, helps both to improve the wellbeing of its inhabitants and make the city more attractive.
The Riverfront General Plan, being implemented since 2008 (see Figure 5) has been promoting regeneration of the riverfront based on environmental concerns, making Lisbon more competitive as a welcoming city for people and investments. It includes measures for the integration into the city’s ecological structure (further connection with other green areas and corridors in the city, as well as the city's drainage plan for flood control). It creates a diverse range of leisure and sports activities, joining the new urban spaces with the river and protecting the city from rising sea water levels due to climate change (Lisbon: a new relationship with the river).
