Restoration of an urban wetland: Humedal Angachilla
One of Valdivia's (in South Chile) southern peripheral neighbourhoods reaches the river of Angachilla which in time led to the creation of an urban wetland, a beautiful and large urban nature reserve of the city of Valdivia. The city of Valdivia is inserted in an extensive network of rivers and coastal wetlands, which penetrate the city through estuaries, hualves and meadows. The Angachilla estuary wetland is one of the most important, connecting the southern sector of the city with the Valdivia River estuary.
These urban wetlands provide important ecosystem functions that directly benefit citizens. Since 2007, the residents of Villa Claro de Luna (neighbourhood) together with various social organisations have worked on the recovery of the Angachilla Wetland, a natural space of great ecological and social value located in the city of Valdivia. Actions included carrying out cleaning, restoration and environmental education activities to recover a place that, abandoned and without any protection from the authorities, was converted into a clandestine garbage dump.

Resilient Rosario
From 1998-2002 Argentina went through an economic depression, which began after the Russian and Brazilian financial crises, caused widespread unemployment, riots, the fall of the government, and a default on the country's foreign debt. Rosario, the third-most populous city in the country, was not a stranger to the crisis' effects as many of its inhabitants were now living under the poverty line. Coupled with this, climate change was heating up the city and making rainfall more erratic, leading to both flooding in Rosario and fires in the nearby river delta. To tackle urban inequality and climate change the Municipality of Rosario developed a program called "Urban Agriculture Program" which aims to give low-income residents access to underutilized and abandoned public and private land to cultivate food. Over the years, the municipality evolved the program into a cornerstone of its inclusive climate action planning. (1)
Let's go green!
In November 2019 the municipality of Hammam Sousse alongside one of the local schools initiated a climate intervention by planting trees next to the banks of the river Oued El Hammam. The municipality of Hammam Sousse is located in the central-eastern part of Tunisia (Sahel region), and as a coastal city, it enjoys a warm Mediterranean climate with a dry summer. The Mediterranean region is ranked among the regions which are the most vulnerable to the effects of climate change and the intervention focused on implementing solutions to mitigate these effects.

Million Trees
The Million Trees project was a programme launched by Auckland Mayor Phil Goff in 2017 to plant a million predominantly native trees and shrubs over a period of three years (Ref. 1,2,3,4). It aimed to make Auckland a greener, more beautiful place while creating carbon sinks, protecting the city’s waterways and improving the city’s living environment (Ref. 2,4). The programme engaged a variety of actors in the planting activities, including local boards, iwi, schools, service and social sector groups, private entities, the council group, the New Zealand Transport Association (Ref. 1). Particularly notable partnerships included those with the Department of Corrections and the Trees that Count Trust (Ref. 2,4,6).
The initial goal was met in 2019, and the project has been renewed for 2019-2022 (Ref. 1,7).

Air quality project at Hunters Bar Infant School (BREATHE)
This project started as a grassroots movement by Hunter’s Bar Infant School (HBIS) in Sheffield when they were seeking to actively help to protect children from air pollution. HBIS led a fundraising campaign that, in collaboration with the University of Sheffield, provided the base to create a green barrier in their playground. The NBS is part of a bigger study called BREATHE that provides the science behind the project, which involves the design of the green barrier, the assessment of its impacts and a feasibility evaluation for installing green barriers in other schools in Sheffield and in Buenos Aires.

Gardening Rome: Public Space Transformation
Urban gardening developed in Rome as a reaction to the unequal distribution of available green spaces in densely populated areas of the city, and to the lack of care for the already existing ones. Since 2006, a large number of associations and informal citizen groups have started to engage in collective gardening by performing both Guerrilla Gardening-style actions and long-lasting community gardens projects run by local associations. This social and spatial transformation is turning most of its urban voids and interstitial spaces into places for collective enjoyment thanks to the spontaneous engagement of local dwellers. [1]
Pocket Parks in Budapest
The creation of pocket parks is an urban initiative that has steadily grown throughout Budapest since 2010 (Reference 1). Most of these projects are citizen-led, but there is often support provided in the form of education and consultancy by initiatives such as the Contemporary Architecture Center (KÉK), or sometimes the local government (Reference 8). These spaces, typically covering an area of 1400 square meters only, are multi-functional and provide a space for small-scale food production, recreation, community sharing, and can be a fundamental element of neighbourhood rehabilitation. Moreover, it provides positive environmental effects such as water retention and the improvement of the area's micro-climate. Pocket-parks are critical in increasing the number of green areas in neighbourhoods that have limited space. (Reference 9)
Porto Biospots Network
The Porto Biospots Network is a partnership of the Municipality with "Infraestruturas de Portugal", and is a network of urban forest areas (predominantly autochthonous) that aims to allow the reforestation of adjacent transit routes, major highway nodes, and routes of circulation within the city, transforming environmentally poor lands into green areas that provide multiple ecological services. This initiative foresees the reforestation of 14 areas and the planting of 10,000 trees by 2021, having already completed 2 roads, with a total of 1305 native trees planted. The biospot is the materialization of a part of the Municipal Ecological Structure of Porto. [1][4]
The Field Group Duddingston
The field is a 3.5 hectare of grassland, grazed by horses for over 20 years. After it fell vacant in early 2011, a group of local residents (“The Field Group”) negotiated a community lease with its owners, City of Edinburgh Council, with the aims of creating an orchard, creating/restoring semi-natural habitats and encouraging its use for quiet recreation and informal education. Members can volunteer their gardening labour or donate money. They can then participate in a garden run for the community – whether to pick the vegetables, learn fruit-growing, help to keep the chickens or just enjoy the space. [ref 1, 2]
John Muir Pollinator Way
The John Muir Pollinator Way is an initiative by the NGO Buglife to create and restore pollinator habitats along a 215 km long-distance active travel route – The John Muir Way – across the densely populated central belt of Scotland. The John Muir Pollinator Way is the first B-Line ‘pathway’ in Scotland and stretches from Helensburgh in the west to Dunbar in the east (Emilie). It is an ambitious project given the length (215 km) of this pathway. It connects nine different local authorities and 40 km of the total length falls within the Edinburgh local authority area (Burgess, 2016). This not only serves to halt the process of declining pollinator numbers providing crucial ecosystem services, but also helps people to connect with nature. Between July 2015 and March 2017, project partners and volunteers have transformed 19 sites into species-rich grassland. [ref 1]
