Restoring ecosystems and their functions

Alcaldía de Medellín - Green Corridors Initiative

Medellín, like many other cities, faces rising temperatures, worsened by the urban heat island effect—concrete and tarmac absorbing the sun’s power, radiating it out as heat and keeping the city warm long after the sun has gone down. It doesn’t have to be that way, as Colombia’s second-largest city, Medellín, is showing by embracing nature-based solutions.

With the Green Corridor project, which won the 2019 Ashden Award for Cooling by Nature Award, supported by the Kigali Cooling Efficiency Program and in partnership with Sustainable Energy for All, Medellín’s city authorities...

Green corridors: Ventilation corridors network, Stuttgart

Green corridors are linear parks that help renature cities by connecting green areas to one another to form urban green infrastructure networks. They are often retrofitted along areas of abandoned traffic infrastructure, e.g. railway lines, or waterways to create interconnecting parks. Green corridors are particularly beneficial for urban biodiversity as well as cooling cities and improving air quality by providing cool air pathways.

The city of Stuttgart took this concept and implemented it on a large, city-wide scale. Located in a valley with low wind speeds, the city is prone to...

Farfalle in ToUr

The project promotes urban butterflies conservation, thanks to the involvement of fragile people as citizen scientists. It aims to create and connect Butterfly oasis, to allow butterflies to cross the city; and to involve people with mental or physical disabilities, to fight the social stigma

Shanxi Qixian Wetland Park Restoration Project -Experience- AFD financed

Project introduction:

The Changyuanhe river is in Qixian, Jinzhong City, Shanxi Province, in North and Middle China and become the main axis of the project, both by its cultural and ecological important for the country. In the past, there were large areas of marsh wetlands along the river, which can regulate and enrich the ecological diversity with good water power. Today the contrast between the upstream natural area (which is still well preserved) and the downstream area (which is dry for four months of the year) is astonished. The project aims to afforest the 30km river...

Mirafiori Sud Living Lab

The project ProGIreg is funded by the European Commission under the Horizon 2020 programme and will run from June 2018 until 2023. ProGIreg stands for ‘productive Green Infrastructure for post-industrial urban regeneration’: nature for renewal. ProGIreg develops self-sustaining business models for nature-based solutions, based on a scientific assessment of the multiple benefits they provide for social, ecological and economic regeneration.Together, local citizens, governments, businesses, NGOs and universities design the nature-based solutions and make them happen.

Habitat enhancement of stone clad sea walls.

Seawalls are usually seen only as flood alleviation structures rather than as having other possible functions to benefit the wide environment. Where new walls are being installed there is opportunity to include more sympathetic “nature friendly” textured finishes to improve or maintain biodiversity. Where seawalls are already installed, retrofit enhancement measures provide significant opportunities. Small alterations were made to the mortar pointing between decorative stone cladding of a section of vertical concrete wall during construction of the Shaldon and Ringmore Tidal Defence Scheme...
