Developing climate change adaptation; improving risk management and resilience

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...

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

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...

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...

In response to the social challenges and environmental impacts caused by urban growth, Bogota adopted the incorporation of green and blue infrastructures in several urban planning instruments. The most important action was the implementation of the local concept of Main Ecological Structure (EEP for its Spanish abbreviation) in 2000. The EEP's purpose is the protection and management of ecological networksthat reconcile urban development with the conservation of the structures and functions of ecosystems, as well as their ability to provide ecosystem services.
