Social change (e.g. social relationships, networks and dynamics within them)

In Egypt, knowledge about climate change remains limited, particularly among the younger generation. While all children globally face the challenges of a degrading natural environment and climate change, some are more vulnerable than others. This vulnerability is often influenced by the quality, availability, equity, and sustainability of essential services such as water, sanitation, healthcare, nutrition, and education. In response to these concerns, Egypt has taken steps to empower its youth to engage meaningfully in international efforts to combat climate change.
In 2022, with the support of UNICEF, the United Nations in Egypt, USAID, and the Embassy of Switzerland, Egypt's Ministry of Youth and Sports and Ministry of Environment launched the EGYouth4Climate Caravan. This initiative aims to raise awareness among children and young people about climate issues, encourage climate action, and provide a platform for youth to share their opinions and ideas. The caravan hosts a range of activities, including capacity-building sessions, youth dialogues, competitions, festivals, theatrical performances, bootcamps, and awareness campaigns.
One of the caravan’s stops was at the Nasr Youth Center in Alexandria, where a seed-planting workshop was held as part of the caravan’s reforestation activities. This workshop offered children a hands-on learning experience, teaching them about the importance of trees and providing an opportunity to plant seeds and trees across the center’s grounds. Through such initiatives, the EGYouth4Climate Caravan fosters climate literacy and environmental stewardship among Egypt’s youth, empowering them to take active roles in shaping a sustainable future.

The project to redevelop Archipelagos Square in Cagliari aims to transform this key urban space, which serves as a gateway between the city and its coastal areas, into a more functional and aesthetically pleasing environment. Currently, the area lacks cohesive design, leading to unregulated use and its transformation into an informal parking lot. The redevelopment will address these issues by enhancing the pedestrian experience and reducing vehicular traffic. Improvements in public comfort and safety will include better rainwater drainage, the removal of architectural barriers, and the creation of accessible pathways for all.
This project emphasizes environmental sustainability and the preservation of the local landscape. Key interventions include revitalizing green spaces, safeguarding native vegetation, and removing invasive species. Integrating walking and cycling paths will improve connectivity between the city, Marina Piccola, and Poetto beach, fostering outdoor recreational activities. A designated eco-system filter will recreate the natural dune environment, blending pedestrian areas with the surrounding landscape.
Funded by the Fondo Sviluppo e Coesione (FSC), the project has a total budget of 3 million euros, with construction lasting 10 months starting in October 2023. The redevelopment reflects the broader goals of Cagliari’s administration to promote sustainable urban mobility and improve the public realm, contributing to the city's vision of becoming a hub for nautical sports while enhancing the overall quality of life for residents and visitors (Refs. 1, 2, 3 & 4).

The Recovery of Cienaga Juan Polo project is primarily aimed at reopening the natural mouth of the Manzanillos to restore water flow between the sea and the Juan Polo coastal wetland, which has been affected by human activities leading to high salinity and water stagnation issues (ref 2). The project is led by Fundacion Serena del Mar. Environmental and social sustainability are core components of the project design, which has included extensive community consultations since 2013. These consultations have resulted in agreements covering employment opportunities, education, and infrastructure development (ref 2). Key implementation activities include the reforestation of mangroves and targeted interventions to address ecological degradation, such as increased salinity, water stagnation, and biodiversity loss (ref 2). The project also seeks to enhance the quality of life for surrounding communities by restoring traditional economic activities, particularly fishing, and integrating sustainable urban planning elements such as canals, sluices, and navigable waterways. These features are designed to support the development of a "blue corridor" for aquatic mobility within Serena del Mar (ref 2, 3). In addition, it also contributes to local capacity building through environmental education programs that engage community members, researchers, and NGOs in biodiversity monitoring and sustainable practices​ (ref 1).

Airfield Estate, based in Dundrum, South County Dublin, is a dedicated sustainable food hub and Dublin’s only working urban farm and gardens. The 38-acre site, originally owned by the Overend family, attracts over 120,000 visitors for a fun day out including families, garden enthusiasts, schools, weddings and businesses.
The community garden at Airfield Estate is based on a partnership between the Estate and Toast corporation, a digital technology platform built for restaurants with an office in Dublin. The community garden was created to produce sustainable fruit and vegetables while also offering opportunities for people to learn about environmentally-friendly food production, empowering them to make more informed food choices. The Toast.org Community Garden at Airfield Estate will be a resource centre for education on nutrition, food sovereignty, seed saving, biodiversity, conservation, and resource management, supporting Toast.org’s mission to enrich the food experience for all. The community garden will also support Airfield Estate’s ambition to be Dublin’s sustainable food hub and help bring Dublin on its journey to be known as a world-leading sustainable food city (2, 3). The grounds will be accessible to everyone, from the local community and vulnerable groups to corporate employees, and the space will host horticulture talks and workshops on various topics. The partnership between Toast.org and Airfield Estate began in 2021 when some of Toast’s Dublin-based employees volunteered with the charity. The launch of the community garden is one of several ways Toast.org will support Airfield Estate throughout 2023. (2)

Alexandria is one of the vulnerable cities facing climate change (1). From rising sea levels, pollution, extreme rise and fall in temperature and the urban heat island effect, Alexandria is battling significant challenges (1). The city is also worldly renowned for it beaches and gardens that act as the lungs through which the city breathes, and are considered a haven for its people (1). Unfortunately, in the last ten years, there has been a decrease in parks and green areas, which is a cause for concern (1). This shrinkage comes at the expense of urban expansion and the establishment of Commercial and profitable projects, which is a challenge facing the environmental balance and cultural heritage of the city (1). To address the nature of the challenges and climate changes and their effects in Egypt, the president launched the "The 100 Million Trees Initiative" was brought into action in 2022 as part of the Egypt 2030 Vision (2-3). The campaign is meant to double the per capita share of green spaces across the country, improve air quality and people’s health, and reduce greenhouse gases. It will also aim to recoup economic benefits from the trees, including wood and olive oil (3). As part of this initiative, the governor of Alexandria was tasked with taking care of the green spaces and improving the aesthetic and civilizational level, within the scope of Alexandria's neighborhoods and centers (4). In 2023, the gardens department carried out the planting of 812 trees and shrubs of various types within the scope of Al-Muntazah 2 Neighborhood during Week 25 to continue the work of the presidential initiative to plant 100 million trees in the governorate's neighborhoods (4).

Tirana's urban development has set a new record in 2022, when more than 1.8 million square meters of new buildings were constructed (Ref. 5). This rapid development increased the need for accessible urban green areas. At the Tulla Urban Farm, a wide audience is trained to create those green areas in their yards, balconies and roofs with the added benefit of growing produce for their own needs (Ref. 1,2,5). This practice of food autonomy is deeply rooted in Albanian culture but has been lost in urban settings where concrete has taken over the city (Ref. 1). Tulla Urban Farm addresses this issue by providing an inclusive space for people of diverse backgrounds to come together and experience urban gardening first hand under the guidance of professionals from the Agricultural University of Tirana (Ref. 2,3). In these "urban agricultural schools", workshops, seminars and discussions are held to re-cultivate traditional agro-cultural practices and knowledge that will benefit the participants, many of which are from marginalised backgrounds (Ref. 1, 4). All these activities are facilitated through the rooftop greenhouse of the Tulla Cultural Center, which harbours over 300 plants (Ref.1). As such, Tulla Urban Farm not only provides a space for experiencing and learning about plants but also for social interaction and building a community that also addresses more serious issues such as mental health in a society that faces high rates of unemployment (Ref. 1).
The project had received inital funding from the German GIZ in 2022 and won the Cultures of Resistance Award through which it financed the first two years of its programme and enabled free participation at the urban agricultural school for all participants (Ref. 2,4).

The urban farm of Lak'a Uta is an initiative launched by the NGO Fundación Alternativas, which established the first community garden in Bolivia, located in the city of La Paz at an altitude of 3,600 meters above sea level (1-3). The initial plan was to develop the garden on private land, but since the goal was to create an open space accessible to all citizens, the project eventually sought a public location (3). The subdistrict of Cotahuma granted them permission to use the Lak'a Uta park, an abandoned area rendered unusable by two landslides in the previous year (3). Through voluntary efforts and an investment of 2,800 euros, the land was transformed over three years to accommodate 40 plots of 16m² each, with individual families cultivating a variety of vegetables (3).
Now celebrating its 10-year anniversary, the project adheres to many principles of organic agriculture in an urban setting (5). The area has become a biodiversity hotspot, featuring an artificial pond, 16 wild plant species, and 39 fauna species, including 34 bird species, two types of frogs that provide natural pest control, and three bee species (3-5). Compost is produced naturally using waste management practices and worms (4-5). In addition to edible vegetables, the garden produces medicinal plants, some of which help stabilize the soil and prevent further landslides (3-4). The infrastructure also includes a rainwater collection system (3-5).
Originally, the project aimed to improve access to food, particularly in response to the growing urban population (1-3). Over time, it has also fostered a strong sense of community, while promoting urban gardening through educational workshops and disseminating information nationwide (1-5). It is estimated that 20,000 people have been educated on urban agriculture, healthy eating, and reconnecting with nature (5). The project has also contributed to shaping a local government law supporting urban gardening within the municipality (3).

In 2021-2022, the fenced grassy area beside the Ballyfermot Community Civic Centre was transformed into a welcoming 'people’s park'—an open green space for the community (2). Designed by Dublin City Council’s Parks, Biodiversity, and Landscape Services, the park reflects ideas from local residents gathered over eight months of on-site conversations and two community consultation events.
The new park features a winding perimeter path, earth mounds planted with a variety of trees and plants for seasonal color, and infrastructure to support small community gatherings. An open pergola and a designated market space for food, plant, and craft markets provide inviting spots for social events. Along the park’s edge, a movement trail with playable elements for exercise and play adds a dynamic feature to the space.
Furthermore, a Jackstraws See-Saw is ideal for older children to play in groups and learn about movement whilst also being a tremendous informal seating area for them to gather and chat. Trees cover the See-Saw, offering shade and shelter from the weather, making it a great social space all year round. A Rope Course provides a physical challenge for older children to climb and balance at height while exploring the area. Informal play opportunities are found throughout the park to, with trees, fallen logs, benches and planting that create sensory, imaginative and physical play experiences. (5-7)
Additionally, an edible garden is planned to be developed collaboratively with local residents over the next 2-3 years (4).

Thessaloniki, Greece's second-largest urban center, is a key hub for economic growth and outward trade in the Balkans. The city hosts the country’s second-largest export port, which plays a crucial role in connecting European trade routes with Asia and China. However, until 2014, Thessaloniki's waterfront was poorly maintained, largely inaccessible, and unattractive. Moreover, major flooding events, connected to extreme weather events, exposed significant deficiencies in the city's flood mitigation infrastructure, leading to damage to housing and critical services. (5, 10, 11)
To address these issues, the Municipality of Thessaloniki launched an International Architectural Competition for the redevelopment of the New Waterfront. From 2006 to 2014, Thessaloniki's waterfront underwent a significant regeneration aimed at benefiting the city's population of 1.1 million and stimulating the local economy. The revitalized waterfront now stretches 3 kilometers between land and sea, featuring 58,000 acres of green space an playgrounds.. In total, 2,353 new trees and 118,432 plants were added across an area of 238,800 m² (Refs 1, 3, 4).
The project also introduced walking routes, sports and recreational facilities, seating areas, and scenic viewing points. The waterfront now has a bicycle path along the entire walkway, and an arbour of 660 umbrella pine trees, serving as shade from the midday sun. Completed in 2014, the New Waterfront has already become a vibrant urban green space, enjoyed by both Thessaloniki's citizens and visitors alike (Ref 4).

In Phoenix, access to native, traditional foods prepared by Indigenous communities is scarce. This disconnection is rooted in the legacy of colonization and the forced assimilation of Indigenous peoples through practices such as mandatory residential schools. The Phoenix Indian School, which operated until 1990, is a stark reminder of these injustices, and deep-rooted systemic inequalities continue to persist today. In response, Indigenous food activists have worked tirelessly to promote traditional foodways and advocate for food sovereignty.
One such initiative is led by Native Health, an urban Indian health program that provides primary medical, dental, behavioral health, WIC, and wellness services in Phoenix. In 2019, Native Health launched a community-based garden initiative to reconnect urban Indigenous communities with their traditional life ways. The Native Health Traditional Garden was initially established on a 15-acre plot of vacant land, which sat atop the remnants of a notorious boarding school. However, when an investment firm purchased the land, the garden was displaced and forced to relocate. It downsized to less than an acre of space within a larger community garden project known as the "KeepPhoenixBeautiful Garden."
Despite these challenges, the Traditional Garden continues to thrive, drawing from Indigenous agricultural techniques such as Akimel O’odham canal irrigation, Zuni waffle beds, and Diné dry farming. The garden focuses on cultivating traditional, Indigenous, and desert-adapted plants, including corn, beans, squash, gourds, peppers, sunflowers, melons, and medicinal plants. In addition to growing these vital crops, the garden provides interactive learning opportunities for all ages, including workshops, youth clubs, pick-your-own events, and monthly community workdays.
The goal of the Traditional Garden project is to offer the urban Indigenous community opportunities for hands-on learning, and increased access to harvested produce. (1, 2)
