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

Submitted by Jemma on 23 November 2021
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...

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

Submitted by Jemma on 23 November 2021
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...

Socio-ecological urban river restoration to mitigate flood risk, improve recreational potential and provide suitable habitats for fauna and flora: The Isar in Munich, Germany

Submitted by Jemma on 23 November 2021
Isar river that flows through southern Germany and cross the city of Munich.

In the second part of the 20th century, three major challenges led towards a new thinking and the implementation of river restoration as a nature-based solution at the Isar.

First, after decades of river regulation, water diversion and hydro-morphological modifications, the resulting degraded morphological status and related losses of ecological and social quality triggered serious concerns from civil society and citizens.

Second, the Isar River was very popular for swimming and other water-related outdoor recreational activities as one of the key elements of the local...
