The Digital Hub, a campus in Dublin 8 offering 49,000 sq. ft. of office, studio, and workspaces for small businesses in technology, creative industries, social enterprises, and artisans, has partnered with Pocket Forests to establish Ireland’s first urban native tree nursery. Located on The Digital Hub campus, the Pocket Forests Tree Hub will grow native Irish trees, including birch, rowan, and alder, to support the planting of over 600 trees throughout Dublin 8 and beyond.
As Dublin 8 district faces a noted lack of green spaces and low tree density, as highlighted by the Mapping Green Dublin project from University College Dublin and local groups, the Tree Hub is set to address this gap. This innovative initiative aims to improve the local natural environment and bolster biodiversity in a rapidly urbanizing area.
Pocket Forests, co-founded in 2020 by Ashe Conrad-Jones and Catherine Cleary, is inspired by the Tiny Forest concept, which brings diverse native plants to small urban plots. Using permaculture methods, Pocket Forests regenerates depleted soil and creates diverse micro-forests on plots as compact as six square meters. This approach, which enriches soil and encourages biodiversity, has a unique capacity to transform urban areas into lush, green spaces, contributing to improved air quality and local ecosystems.
The Covid-19 pandemic has underscored the importance of access to nature for well-being, and The Digital Hub offers an ideal location for this first-of-its-kind urban initiative. The Tree Hub will serve as a valuable resource for greening Dublin 8, promoting community engagement, and fostering a greater connection to nature.
Beyond the nursery, Pocket Forests will run a series of six half-day workshops at The Digital Hub to educate the community on biodiversity, pollination, compost, soil health, and the importance of urban forest ecosystems. The Digital Hub’s Tree Hub boosts well-being, biodiversity, and green space for future generations. (1-5

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.

The Santa Gilla lagoon, a crucial wetland in the Cagliari metropolitan area of Sardinia, has been the focus of several interventions aimed at restoring and preserving its natural and socio-economic functions. The overarching goal of these projects is to rehabilitate the lagoon's ecosystems, improve public accessibility, and promote sustainable economic activities such as eco-tourism and fishing. One significant intervention is the restoration of pedestrian and cycling paths around the lagoon, managed by CACIP (Consorzio Industriale Provinciale di Cagliari) in collaboration with the Metropolitan City of Cagliari. With over two million euros in funding, this project aimed to recover the original profiles of the lagoon's embankments, while removing waste from the area and enhancing the paths for non-motorized mobility (2). Another crucial development was the legal action taken by the Corpo Forestale (Forestry Corps) in 2020 to address illegal constructions and pollution along the lagoon's eastern shores. This action included the sequestration of areas used for illegal fishing activities, where hazardous materials and waste were improperly disposed of, leading to environmental degradation​ (1). Furthermore, environmental groups have made continuous efforts to address illegal dumping near the lagoon, particularly along the SS 195 highway. These groups have actively sought the intervention of local authorities to initiate cleanup operations and enforce regulations against illegal waste disposal​ (4). The projects were implemented primarily to address the significant environmental hazards facing the Santa Gilla lagoon, including pollution from illegal dumping, habitat degradation due to unauthorized constructions, and the overall loss of biodiversity. These activities also aimed to mitigate the socio-economic risks posed by the deteriorating environmental conditions, such as the decline in tourism and sustainable fishing practices (1,2,4).

The environmental and public space recovery project around the Bazurto Market in Cartagena is a comprehensive initiative aimed at addressing the severe environmental degradation and chaotic urban conditions in this vital area of the city. The Bazurto Market, one of Cartagena's most important economic hubs, had experienced increasing levels of disorganization, pollution, and public health risks due to the encroachment of informal vendors and improper waste management (ref 1,2,5). The primary goals of this project are to restore the ecological health of the Caño de Bazurto and the Ciénaga de las Quintas, enhance the quality of public spaces around the market, and improve the overall urban environment (ref 1). Project activities included removal of waste from the surrounding water bodies, installation of protective barriers along the Ciénaga de las Quintas, and the planting of trees to revitalize green spaces (ref 3,4). Emphasis was placed on planting of a variety of tree species, such as Guayacán Amarillo, Ceiba, and fruit trees like níspero and mango. These efforts were concentrated in areas around the Bazurto Market, where green spaces had been neglected or overtaken by informal commercial activities. The project also included the restructuring of vendor locations and public spaces to reduce congestion and improve the flow of both pedestrian and vehicular traffic (ref 5). Educational campaigns were conducted to encourage better waste disposal practices and enhance community involvement (ref 1).

"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.

Martinique is a biodiversity hotspot, home to over 1,500 endemic plants, 70% of which are under threat from human activities. In response to these pressures, the Péyi Vert [Green Country] initiative was launched to plant endemic trees and strengthen the island's biodiversity. Beyond simply preserving species, these trees are crucial in maintaining healthy ecosystems, as they provide essential services such as carbon sequestration, shade, food for human consumption, soil decontamination, pollination, and protection against coastline erosion.
Launched in June 2020 by Entreprises et Environnement (EE), a not-for-profit business association representing 80 Martinican companies, the Péyi Vert initiative aims to plant 1 million native trees (either Martinican or Caribbean) over five years. It can be seen as a Martinique-wide strategy to adapt to and mitigate climate change. Péyi Vert facilitates connections between people who want to plant trees and Martinican companies that serve as financial sponsors. The initiative emphasizes conserving natural heritage by planting endangered species, as well as promoting native species that, while not necessarily threatened, provide valuable ecosystem services or contribute to biodiversity restoration.
Between 2020 and 2023, EE reported planting 50,000 trees (Refs 1, 4, 6, 7). Although individuals can make donations, Péyi Vert primarily seeks funding from companies looking to offset their carbon emissions or enhance their Corporate Social Responsibility (CSR). To achieve its goals, the initiative mainly collaborates with municipalities, companies, and farmers (Ref 3).

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).

The project for Tricentennial Park involves a series of improvements aimed at enhancing its overall infrastructure and appeal. Among the planned upgrades is an enhancement of the pavilion, along with the addition of other site amenities (Ref 1). A lake is also being created as part of the project (Ref 2). Currently, work is underway on phase two, which includes landscaping, the construction of a group picnic pavilion, walking trails, a parking area, and even a misting machine to provide relief during hot weather (Ref 2).
One of the key highlights of the project is the opening of a new playground in 2024, featuring a unique design. The park is laid out in a figure-eight pattern, and a sign within the park highlights its recognition for following “best practices in youth fitness,” encouraging children to stay active through sliding, swinging, spinning, climbing, brachiating, and balancing (Ref 2). This park is the first in Mobile designed exclusively for passive use, without ball fields, providing a space for families and individuals to enjoy the playgrounds (Ref 4). The park fosters social interaction, allowing children to build friendships and create lasting memories while spending time with their families (Ref 4). The park also boasts beautiful scenery, adding an aesthetic dimension to the overall experience (Ref 2).
Tricentennial Park is part of the larger Three Mile Green Trail, a 6.5-mile linear park. A one-mile segment of the trail is located within Tricentennial Park. The trail will be expanded east to MLK Boulevard and west to Bush Park by 2024 (Ref 1).

Rainwater management in Gdańsk presents significant challenges due to the city's hydromorphological conditions, including high groundwater levels and steep terrain. These factors, coupled with the periodic inefficiency of the storm sewer system and the intensification of extreme weather events such as heavy rainfall, have necessitated innovative solutions. Gdańsk has responded by implementing a climate change adaptation policy that promotes the use of open drainage systems, including small retention facilities like rain gardens. These gardens help mitigate the risks associated with excessive rainfall while enhancing urban sustainability.
The first rain garden in Gdańsk was established in the Stogi district at the Flood Control Warehouse on Kaczeńce Street. This facility collects and utilizes rainwater from nearby paved surfaces, aiming to manage rainfall of at least 30 mm during intense, short-term downpours. Utilizing a variety of perennials such as marsh marigold, common loosestrife, comfrey, hemp agrimony, common calamus, and arrowhead, the garden retains and filters rainwater naturally, increasing efficiency and ecological benefits. Rain gardens absorb water up to 40% better than traditional lawns. They reduce rainwater runoff, mitigate flood risks, filter pollutants, improve biodiversity, and enhance urban air quality while lowering temperatures.
The garden was created as part of a broader investment in the Flood Control Warehouse in Stogi, a facility opened in 2017 at a cost of over PLN 5 million. Strategically located near the Sucharski Route and the Martwa Wisła tunnel, the warehouse supports rapid response to flood emergencies, storing over 100 types of equipment, from shovels to large generators. This combination of infrastructure and green solutions demonstrates Gdańsk's commitment to urban resilience and environmental sustainability. (1-4)

This initiative focused on creating a management plan for the Uricani forest, a protected area located near Iasi. Designated as both a nature reserve and a Natura 2000 site, the forest is crucial for its "Dacia oak & hornbeam forests" habitat and the presence of the stag beetle, the largest beetle in Romania and Europe.
Despite existing nature protection designations, the environmental NGO "Asociația Ecoturistică Prietenii Pădurii Bălțătești" recognized the need for an updated management plan. With European funding, the NGO developed a model plan for protected areas in Neamt and Iasi counties, including Uricani forest.
The NGO conducted monitoring activities in cooperation with forestry directorates to assess habitat conditions and stag beetle populations. The goal was to identify risks and requirements for species conservation and design appropriate management actions. Additionally, the organization aimed to promote the area's tourism potential and conduct awareness-raising activities with local communities and schools.
The completed management plan, developed through public consultation and approved by the Romanian environmental ministry, included measures for natural habitat regeneration, ensuring suitable conditions for the stag beetle, addressing illegal logging, pasturing, and waste disposal, and establishing information points and educational activities for the community.
