In 2019 at the Gullele Botanical Garden in Addis Ababa, the Ethiopian government launched a historic tree planting campaign. Over 350 million trees were planted in an ambitious move to counter the effects of deforestation and climate change. The Gullele Botanical Garden was selected as one of the 1000 sites all over the country involved in the Green Legacy Initiative, a national campaign against the effects of climate change. The United Nations estimates that Ethiopia’s forest coverage has declined drastically to a low of just 4 per cent in the 2000s from 35 per cent a century earlier. (1,2) The Botanical Garden was not selected aleatory as it is Ethiopia's only botanical garden and it is a nursery for various indigenous plant species. Its mission is to conserve and promote the Ethiopian diverse plants and tree population and it is a conservation initiative located at the northwestern tip of the Addis Ababa City Administration. The site covers an area of 1000 ha which is representative of the central plateau of Ethiopia. (3)

This intervention was initiated in 2014 in Agege, a slum and a city in itself belonging to Lagos. Agege is one of the 7th most populated low-income communities in Lagos with a total population of around 1,033,064 people. Climate change in Nigeria led to seasonal droughts and floods, causing pressures in terms of food security as well as high temperature and humidity levels which affect directly the economically disadvantaged population in the slums of Lagos. In 2014 a research team at the University of Cardiff alongside community leaders of a Yoruba community in Agege implemented a study on vertical gardens in residential areas with the purpose of alleviating local temperatures and enhancing biodiversity. The implementation started with a study and was continued with the introduction of practical gardens maintained by the local community of 3 residential buildings (one in Suru Street, another in Lagos Street in Agege, and a third in Abeokuta Street).

In 2019, the public initiative "Let's return the rivers to the city" campaign united public forces around the Podborenka river, which flows through the territory of Izhevsk along its entire length [1, 4, 5]. In an urbanised environment, the river was abandoned due to water pollution, poor treatment of stormwater, road and industrial runoff, soil erosion, and due to presence of landfills in the valleys [1, 4, 7]. Therefore, the project's primary goal is to increase the efficiency of urban resources and the creation of new scenarios for resource use on the example of the space of the riverbed of a small river [3]. The project implementation contributes to improving the ecological situation of the Podborenka River, its embankment zone and biodiversity [1, 9]. Also, the project implementers paid particular attention to the education of young people, the development of volunteer movements, and raising the level of the ecological culture of the population [1, 2, 6, 7].

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.

The project is part of a bigger initiative aimed at restoring the coastal forest near the city of Mahajanga in western Madagascar. Alongside 2 international NGOs, the community located in the bay next to the city of Mahajanga implemented the intervention with the ultimate goal being to transition the land into a protected area as part of the greater "Mahajanga Green Belt Project". The regrowing forest will form the northwestern end of the greater Mahajanga Green Belt, with the southeast meets the Ankarafantsika National Park. The project also has a gendered aspect as it aimed to employ mostly the women in the suburbs of the city. (1,3)

In 2015 an innovative project called the "Sweet City" (Ciudad Dulce) was launched in Curridabat. Its main goal was to bring wild spaces into 21 urban neighbourhoods of Curridabat ("spaces of sweetness") and eight corridors ("transitions") and thus linking neighbourhoods and parks through a participatory re-design approach with local stakeholders [3]. The main objective of the Sweet City model is to reintroduce biodiversity into the urban space by focusing on five fundamental dimensions: Biodiversity, Infrastructure, Habitat, Co-existence and Productivity. The interventions of this project included park improvements, sustainable drainage systems, the protection of wetlands, spring water recovery, promoting organic farming practices, and many strategies that help improve biodiversity and motivate citizen participation, finally, as ecosystem-based disaster risk reduction measures and climate change adaptation actions [1].

"The Urban forest strategy (UFS) is a central part of an innovative overarching policy framework of the City of Melbourne underpinning the city's aim to create healthy ecosystems for people and nature" in the period between 2012-2040 (1 p9). The UFS outlines a scientifically-vetted long-term process to re-nature the city with a diverse selection of urban trees and open space for and with the citizens, combining elements of an eco-managerial governance arrangement with an open and reflexive co-governance approach. (1 p11). The Strategy concentrates on 6 areas to achieve its goals: canopy cover, forest diversity, vegetation health, water quality and soil moisture, urban ecology and environmental stewardship among citizens.

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]

The Square Metre for Butterflies project was initiated by the Royal Botanic Gardens of Edinburgh (RBGE), in partnership with the Butterfly Conservation Trust, as an Edinburgh Living Landscape network membership activity. By planting relatively small-sized patches of caterpillar food plants on the roofs of mainly office buildings, the aim of the project is to enhance green roofs in order to increase their value for biodiversity, and for native butterflies in particular. Office buildings in Edinburgh’s city centre are targeted because of their location close to Arthur’s Seat hill, which is the natural habitat of Edinburgh’s butterflies. [ref 1]

The Roerplein pocket garden was a Neighborhood Green Plan project. The Neighborhood Green Plans were an initiative of Utrecht Municipality to support the bottom-up 'greening' of its neighbourhoods. Citizens could propose a variety of often quite small-scaled plans that enhance the neighbourhood by means of green spaces that promote social cohesion and thereby community identity. At the Roerplein, a public square was transformed into a green square by way of a participatory process, assisted by a social entrepreneur. The project aimed to reduce heat stress, enhance social cohesion and the attractiveness of the neighbourhood, promote biodiversity and support recreation (ref. 1).
