Restoring ecosystems and their functions


Heritage zone of Xochimilco: Tlahuac and Milpa alta, Mexico City. The importance of Nature-Based Solutions

Chinampa Atliacac harvest agrochemical-free products in Tláhuac. The chinampa is a cultivation method used by native indigenous groups to expand the territory in the lakes and lagoons of the Valley of Mexico, and they use them to grow flowers and vegetables.

Xochimilco is an important tourist attraction for Mexico City and because of thi,s public policies have been focused in conservation, tourism infrastructure and ecotourism. Therefore there is now a priority to address social and environmental challenges including: the dredging and cleaning of the canals, garbage collection and reforestation of channels, exotic species control, improving the hydraulic infrastructure, Axolotl conservation, Chinampas rehabilitation, and productive projects.

Natural systems or nature based solution have been suggested and implemented in order to reduce...


Multisectoral and multiscale articulation for urban regeneration in Medellín and its Metropolitan Area

Medellin's accelerated growth has increased occupation of risk areas such as mountain slopes and has deepened problematics such as air pollution.

In response to the challenges arising from the urban expansion of Medellín and the close association with neighbouring municipalities, the Metropolitan Area of the Aburrá Valley (AMVA for its Spanish abbreviation) was established in 1980 as a regional public transportation and urban environmental authority. Within this context, the current city government, in co-ordination with other municipalities of the AMVA, focused its development plan (Plan de Desarrollo) priorities on the implementation of actions to improvethe urban environment, including nature-based interventions from the...


City districts as testing grounds: integrated sustainable stormwater solutions through retrofitting in existing neighbourhoods and as part of urban transformation processes in Malmö, Sweden

Bo01 in the west harbour Malmö.

The city’s green and blue areas have a long history, and are even today seen as an important and integrated part of the city of Malmö, as reflected in the recent Master Plan. The ambitions are to create a close, dense, green and mixed functioning city, with densification as a driver, rather than expansion into the outside highly productive farmland. Urban green is a vital component of the future of the city and, in the master plan, is brought forward under such diverse headings as Green City, Green and Blue Environments, Biodiversity, Countryside and Agriculture, Children’s Perspectives,...

The Green Corridors Network as the background of a NbS approach in Lisbon, Portugal

UAG parks were installed since 2011 as part of a process of social inclusion, where quality of the public space was the decisive point for citizen engagement and approval.

For several reasons, protecting important ecological areas in Lisbon from urbanisation has become difficult. Remnant areas of natural habitat have gained particular importance in consolidating the green corridors network, benefiting from the fact that much of this land is still within the municipality’s property holdings. The “Lisbon Green Plan” published in 1996 set out the approach used in 2008 to implement safeguarding measures to protect the ecological structure under development threat at that point. It triggered an update to the Lisbon Master Plan at a time when climate issues were...

Barcelona wants to renature the city and create, in this period, 165 ha of new green spaces, which increases the green spaces/inhabitant ratio by 1m2. As Barcelona is a compact city, there are various strategies to improve, transform or create new green spaces. The actions will take place at various urban scales (street, district or city scale) and...
