Facilitating sea turtle nesting
The beach of Vétiver, located in the municipality of Case-Pilote, is one of the most important nesting sites for the critically endangered hawksbill turtle (Eretmochelys imbricata) in Martinique. It is also a nesting ground for the green sea turtle (Chelonia mydas), another endangered species. As one of the last minimally urbanized beaches in the North Caribbean of Martinique, the site plays a vital role in the conservation of these species. In addition, fishing restrictions in the area significantly reduce the risk of turtle mortality caused by accidental capture in fishing gear, which is the leading cause of human-related sea turtle deaths in the Antilles.
However, the site faces several stressors that hinder successful nesting. The surrounding vegetation is severely degraded due to invasive alien species, and much of the shrub and tree cover has disappeared from the backshore, where turtles prefer to nest. Without adequate vegetation, hatchlings are left exposed to the heat. Additionally, the beach is frequently disturbed by local residents and visitors for recreational activities. With no designated parking area, cars often park directly on the beach, compacting the soil and further limiting the chances for vegetation to recover or turtles to dig nests. This compaction forces turtles to lay their eggs closer to the shoreline, increasing the risk of nests being washed away by heavy swells.
In 2022, the non-profit organization "Asso-mer" and its partners launched the Véti’Vert project on a previously neglected public green space. Through environmental restoration efforts, they created a nesting enclosure on the backshore to mitigate these stressors and improve the conditions for sea turtle nesting. The project also engaged with local residents to increase the chances of success (Refs 1-3).

Mapinguari National Park
Mapinguari National Park, located in the Amazon region of Brazil, is a protected area distinguished by its rich biodiversity and vast expanse of untouched tropical rainforest (2). It was officially created on June 5, 2008, by decree, covering an area of 1,776,914.18 hectares (2). The Chico Mendes Institute for Biodiversity Conservation (ICMBio) manages the park. It is linked to a management plan encompassing several nearby conservation units and their areas of influence (2, 3). Its main goal is to preserve the valuable natural ecosystems and scenic landscapes of the Purus-Madeira interfluvial region, which includes savanna enclaves (2, 3). The ecoregion where it is located has a high priority for botanical conservation due to parameters such as species richness and endemism (3). Additionally, the area presents great environmental heterogeneity, with several isolated and unique ecosystems, aspects that have been considered for fostering scientific research and public visitation, with programs for environmental education, recreation in contact with nature, and ecotourism (3). On March 8, 2013, an advisory council for the park was established to involve various stakeholders in decision-making and the effective conservation of the park (2), and in 2018 a Management Master Plan was established, seeking to develop an integrated approach for the protection and proper management of the region, especially considering the socio-environmental impacts of the construction of the BR-319 highway and the deforestation caused by fires, the expansion of soybean cultivation, land appropriation (7) and cattle ranching from the neighbouring state (3, 10). It was established as a Natural Park in 2008, but over the years it has undergone changes in land regulations, adding or decreasing its size as certain mining activities have been allowed in the buffer zone (2)
Healing earth: reforesting parts of the Amazon
According to data from the National Institute for Space Research (Inpe), Rondônia ranks fourth nationally among the states with the highest number of detected fire outbreaks (2). In response to this issue and to restore devastated areas in the Amazon, Terra Cura was established in 2016 by resident Luana Lopes, promoting the planting of more than a thousand trees in the Porto Velho region (1). The areas benefiting from this initiative were those degraded by deforestation, causing erosion along the riverbanks (1).
This reforestation effort took place in the scenographic city of Jerusalem of the Amazon, from 2016 to 2022, a cultural and touristic complex in Porto Velho, where erosion caused by deforestation was observed along the riverbanks next to it (2). It was developed as a collaboration with the club and the founders of the Associação Clube Teatral Êxodo, who gave the space so that we could recover the land (3).
The project focused on developing an agricultural strategy known as syntropic farming, by implementing an agroforestry system. This approach seeks to reorganize and restore the natural environment, creating better conditions for planting and allowing trees to thrive. In the reforestation process, volunteers and experienced technicians worked together Additionally, the project included a nursery used for donating seedlings and for offering forestry and agro-construction courses to the community, held in the reforestation area (2).
The Terra Cura project, in addition to working on reforestation and recovery of degraded areas, promoted environmental and cultural integration at the site, promoting sustainable fairs and bazaars, training courses in ancestral practices such as soil cultivation and bioconstruction, and thematic events, bringing together artists and local communities (3). Although they were evicted from the area surrounding the scenic city of Jerusalem (5, 6), they are still active in the area.

Adopt a linden tree
"Adopt a linden tree" is a project that involved the planting and adoption of linden trees in the city of Iași, spanning from 2019 to 2023 across three editions (1 to 8). The campaign was spearheaded by the National Athenaeum of Iași, in collaboration with the Mihai Eminescu Association from Vienna (2). This initiative was launched in celebration of the Athenaeum's 100th anniversary, and it specifically chose the linden tree because of its deep-rooted symbolism in the city of Iași. The tree is not only a natural landmark but also carries cultural and historical weight, as it is closely associated with Romania’s national poet, Mihai Eminescu, who is known for his love of linden trees.
In 2019, 100 linden trees were planted, a number that was repeated in 2020. In the 2023 edition, 50 trees were added, bringing the total number of trees planted through this project to 250 (1 & 4 & 5). An important and unique aspect of the initiative is the "adoption" of the trees by volunteers who participated in the campaign. These volunteers not only lent their names to the trees but also took on the responsibility for their care, ensuring the trees' survival and growth until they reached maturity .
Volunteers were encouraged to participate, and the campaign was supported by donations from individuals, businesses, and public institutions. The municipality of Iași also contributed by providing funds, approving the initiative, and preparing the land through its subsidiary, Servicii Publice Iași S.A., reflecting strong public-private collaboration.
Beyond its cultural significance, the campaign aimed to achieve several other objectives. These included enhancing the city’s aesthetics, promoting community engagement, and improving the quality of life in Iași by contributing to cleaner air and a healthier environment . The initiative also aimed to raise environmental awareness among residents and foster a stronger sense of responsibility toward the natural world. (1-8)

Los Remedios park
The old Altadis tobacco factory in the Los Remedios neighbourhood of Seville is being transformed into an area with offices, hotels and lots of green space. New green space will connect existing green areas next to the river, resulting in a total of 13 378 m2 of green areas within 3 ha of public space. The park will increase the number of trees in the area by 60 per cent, creating a lot more shaded areas, which are needed during the hot summers [Ref. 1-5]. Additionally, the trees will contribute to carbon sequestration, improve air quality and promote biodiversity [Ref. 5]. The park is meant to become a popular destination for recreation, new entrances and a bridge over the river will connect the surrounding neighbourhoods to the park [Ref. 1-3]. There will be areas for physical activity, dog walking and play for children [Ref. 1, 4]. The project is being carried out by real estate company KKH Property Investment, which owns the land and will invest 250 million EUR in the project as a whole, of which 5 million EUR is designated for green spaces. KKH has made an agreement with the City of Seville to ensure the project has benefits for the area and its citizens, and follows previous plans for the area, which have involved citizen participation [Ref. 3, 6, 9].
Nano forest in Berlin
On a small roadside green space in Berlin, a tiny forest was created. The idea of Tiny Forests comes from Japan, there are already some in France and the Netherlands, and since 2020 also in Germany. Tiny forests are constituted of trees planted densely next to each other in small spaces, such as tiny green roadsides.
At Oderstraße, the NGO TinyForestBerlin planted an even smaller forest, a nano forest on a roadside where trees cool down the area, filter the air and create a habitat for insects. Trees in urban areas loosen up the dense and degraded soil, allowing it to store carbon and let rainwater properly seep into the ground to prevent urban flooding. Roadsides are hardly utilised or recognized in their environmental potential, such as hosting a nano forest. Projects like the one implemented by TinyForestBerlin present an approach for collaboration between the district and civil society, as the district's park department lack the capacity to maintain small roadsides. The project at Oderstraße is the first official tiny forest in Berlin, as a previous planting campaign in Friedrichshain was not entirely legal due to missing approval of local authorities. (Ref. 2; Ref. 5)
The TinyForestBerlin association has set itself the goal of creating such small nano-forests all over Berlin. An ambitious project that aims to enrich the city's green spaces and contribute to improving the urban climate. The trees planted on Oderstraße are one of many smaller planting projects that are spread throughout the city on public as well as private land. (Ref. 3)

Urban Natural Area Ciric
"Urban Natural Area Ciric" is an initiative aimed at designating the forest and lakes of the Ciric area, located on the outskirts of the city of Iași, as an Urban Natural Area. To achieve this goal, the initiating organizations—NGO Civica and the Ornithological Association of Iași (SOR)—have developed a comprehensive report focused on the Ciric natural area, which monitors species and habitats while identifying pressure points on biodiversity and necessary conservation actions, as well as the benefits these areas provide.
In the Ciric area, various flora and fauna species have been identified, with some holding high protection status (14 bird species) or being of community importance and conservation interest. However, this ecological richness faces threats, as factors such as rapid urbanization, water pollution, and waste disposal have been identified as significant risks to the ecosystems.
In response to these challenges, the NGO aims to collaborate with the municipality to create protective municipal laws that will not only recognize the area as an Urban Natural Area but also ensure its inclusion in development plans. This partnership seeks to establish regulatory measures and strategies that will safeguard and enhance the biodiversity and ecosystems of Ciric. Additionally, the organizations have highlighted the social and physical benefits of the area for residents, including flood regulation and prevention, pest control, provision of clean air, and recreational and scientific opportunities.
To further raise support and awareness for their efforts, SOR and Civica conduct guided tours, educational workshops, and photographic exhibitions. They have also set up two informational panels in the area that highlight the biodiversity of Ciric. Furthermore, the two NGOs have partnered with regional organizations to create the "Rețeaua națională de arii naturale urbane" (The National Network of Urban Natural Areas) and have received funding from the EEA Grants.

Growroom
The Growroom is a spherical urban garden made of plywood, designed as a temporary installation in Gdańsk’s Strzyża district. Originally created by Danish architects Sine Lindholm and Mads-Ulrik Husum, the structure was adapted for this location as part of a collaborative initiative. It provides a small, functional space where residents can plant and enjoy greenery within the city.
In Gdańsk, the Growroom was used to cultivate flowers, herbs, and strawberries, with the plant selection curated by Joanna Paniec, a specialist in the city’s green initiatives. A central bench within the structure offers a simple resting spot for visitors. While visually appealing, the installation primarily served as a short-term experiment in integrating greenery into urban settings.
The project was co-financed by the Danish Cultural Institute, the Danish Ministry of Culture, the Danish Ministry of Foreign Affairs, and the Environmental Department of the Gdańsk City Office. It was brought to Gdańsk by the Polish foundation Kultura nad Kulturą and conceptualized by Agnieszka Wołodźko, a painter, exhibition curator, and author of the blog Pomiędzy sztuką a życiem. The installation was in place from [add dates if available], after which maintenance was handed over to the local community.
The Growroom was not intended as a long-term urban feature but rather as a temporary initiative to explore the role of small-scale green spaces in cities. While it provided a brief opportunity for local engagement with urban gardening, it was ultimately a short-lived addition to the district. (1-4)

Bring Nature Home
Bring Nature Home project, partly financed by and implemented under the New European Bauhaus programme by the organisation "UrbanizeHub", is an initiative focused on encouraging and helping the city of Iasi to become more green while strengthening urban communities (1 & 3). More concretely the project sought to transform an unused space in a residential area of a neighborhood in Iasi through a "biophilic design", with the involvement of the local community (1 - 5). The space was then transformed into a green area that would help the residents reconnect with nature (1 & 4). The implementation later helped develop a handbook that could be used to reproduce the methods of the initiative in other urban settings (4 & 5).
Involving the local community, including children from the nearby daycare, the project conducted five workshops. These workshops focused on educational activities, improving the connection with urban nature, and ultimately creating an urban garden which included perennial plants, and insect and bird houses (5, pp. 53 to 58).
Beyond community engagement and inter-generational dialogue, the project highlighted the importance of natural elements and biodiversity in urban settings. It also facilitated knowledge exchange among public institutions, NGOs, and private companies. With additional funding from IULIUS and municipal approval, the initiative successfully transformed the unused space into a thriving green area (4 & 5, p. 67 & 71).

Community garden on Graveyard
The Prinzessinnengarten Kollektiv Berlin is a community garden in the New St Jacobi Cemetery in Berlin-Neukölln that invites people to join in gardening and experience nature. As part of open gardening days, people can participate in the design of the garden areas and gain experience in the local, ecological cultivation of useful plants. The main aim of their work is to provide opportunities for education and participation. Activities are open to everyone and range from sowing, planting and harvesting to seed production, processing and preserving vegetables, keeping bees to questions of community-based urban habitat design.The community also has its own farm shop where seeds, food and processed products are sold. (Ref. 1; Ref. 4) Numerous projects for recycling and upcycling, innovative cultivation methods, organic beekeeping, composting methods and post-fossil mobility use the Prinzessinnengarten as a platform for sustainable urban living. Artists also work in the garden with participatory methods on the question of how cities and their coexistence can be designed in a sustainable and resource-saving way. Outside the Prinzessinnengarten, offshoot gardens are set up and collaborations are developed to build nationwide and European networks. Through lectures, workshops, study visits and participatory research in the garden, we endeavour to include and further develop the topics associated with the Prinzessinnengarten in discussions and education. (Ref. 7)
The project is located on a cemetery, which has been partially closed since 2016. This means that burials are no longer carried out on the site and the existing rights of use of the 500 or so remaining graves will no longer be extended after expiry. The church association lends the land to the project in exchange for maintenance work on the surrounding grounds. (Ref. 6)
