SDGs National Strategy

The Swedish Geotechnical Institute, a government agency, and the county administrative boards in Västra Götaland and Scania are running a project which tests methods to prevent erosion of coastal salt meadows. Erosion risks destroying unique ecosystems, and the aim is to develop cost-efficient, nature-based mitigation methods that can be replicated in other sites with similar problems. The project is part of an EU-funded Interreg North Sea project called MAinstreaming NAture BAsed Solutions through COASTal systems (MANABAS COAST), which involves other countries in the region [Ref. 1, 5]. Four different salt meadows are included in the Swedish part of the project. The sites are called pilot areas and are meant to test and showcase NBS to inform policy and develop methods that can be used in larger scales in the future. One of the sites is located at Glose in Kungälv municipality within the Gothenburg FUA [Ref. 2-4]. Here, the biodiversity of a salt meadow used for grazing and the adjacent coastal waters are threatened by erosion. According to a new management plan, NBS such as natural barriers will be implemented to break waves and halt erosion, preserving the ecosystems, improving water quality and ensuring the land continued use as a pasture for grazing cattle [Ref. 4].

Alexandria is one of the world’s most climate-vulnerable cities, facing serious environmental challenges that threaten its landscape, culture, and livability. The city is grappling with rising sea levels, pollution, extreme fluctuations in temperature, and the intensifying urban heat island effect, all of which are worsened by climate change. The past decade has seen a steady decline in Alexandria’s parks and green areas, a trend that has raised significant concerns among environmentalists and the public. The shrinking green spaces are largely due to rapid urban expansion and the development of commercial projects, which are gradually pushing Alexandria's environmental balance and cultural heritage to the edge.
In recognition of these pressing issues, Egypt launched the "100 Million Trees Initiative" in 2022 as part of its Egypt Vision 2030, a national plan for sustainable development. The initiative aims to increase the per capita share of green space throughout the country, with objectives that include improving air quality, enhancing public health, countering the urban heat island effect, and reducing greenhouse gases. The initiative is also focused on improving the beauty and cultural value of Egypt's urban areas, aligning with broader goals to build sustainable and climate-resilient cities. Alexandria, being a coastal city that is both environmentally sensitive and culturally significant, has been a focal point of these efforts.
As part of this national campaign, the Governor of Alexandria was tasked with overseeing the enhancement and expansion of green spaces across the city, focusing on both the aesthetics and cultural aspects of the urban landscape. In 2023, these efforts took root in the Al-Muntazah 2 neighborhood, where 596 trees were planted as a contribution to the 100 Million Trees Initiative. This project included the Al-Samad Preparatory and Secondary Schools campus as one of its primary planting sites. (1-5)

The Alexandria Governorate is especially susceptible to the impacts of climate change, a vulnerability exacerbated by its dense coastal communities and rapidly growing population (2). Both demographic shifts and urban development intensify how climate phenomena affect the people and infrastructure of Alexandria (1). Buildings, roads, and other concrete structures absorb and release solar heat, significantly contributing to the urban heat island effect, which is causing temperatures in the city to rise faster than in less developed areas (1). Despite Alexandria’s growing need for cooling green spaces, they currently make up only 0.25 percent of the total area within the Governorate, highlighting an urgent need for environmental interventions (3-6).
In response, Ahmed Gaber, chairman of the Alexandria Water Company, initiated a public awareness campaign in 2023 focused on the numerous benefits of planting green roofs (3-6). Green roofs serve multiple purposes: they extend the longevity of buildings, lower energy consumption, improve air quality, increase biodiversity, manage rainwater runoff, and mitigate the urban heat island effect (3). Furthermore, Gaber has emphasized the visual appeal of eco-friendly roofs, noting that green roofs offer an aesthetically pleasing option that enhances the urban landscape while serving critical environmental functions (4).
This initiative by the Alexandria Water Company marks a pioneering step among governmental organizations in the region, as they lead efforts to address climate and environmental challenges actively. The company has begun planting green roofs across its facilities, including the new Al-Mashishya water station, where green spaces atop buildings are set to bring lasting environmental benefits to Alexandria. Through these efforts, the Alexandria Water Company is working to set an example for public and private sectors alike (3-6).

Alexandria is a city with a special charm, known for its 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 green space due to urban expansion and the establishment of Commercial and profitable projects (1). To address the lack of green space in the city, The Governor of Alexandria has stressed the continued efforts to develop, beautify and plant the squares and turn them into attractive civilized facades, as part of Egypts 2030 vision which aims to move towards a greener city and reduce the effects of climate change. (2). To encourage redevelopment of public green spaces, The Governor launched the “Alexandria shines with its squares” competition in 2023, where the top three neighborhoods with the best redeveloped squares would receive a prize of up to EGP 50,000 [928.45 EUR] (6). The First Al Montazah neighborhood participated in the competition by redeveloping Sidi Bishr Mosque Square (2-5). The 700 meter square was completely upgraded with solar energy, a new irrigation system to conserve water, modifications to the sewer network, and planting the garden with plants that suit the environment (3). The greening activities included planting 400 sticks of various crops in the upgraded square (4).

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.

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).

The Stora Amundö and Billdal archipelago nature reserve is in the southernmost part of the City of Gothenburg. The proximity to the city makes it a popular recreational destination, with about 73000 visitors each year. In 2018, the area was protected as a nature reserve to preserve its recreational, natural and historical values. The status as a nature reserve prohibits any exploitation and other harmful activities in the area. The area of the reserve is 1103 ha, of which 259 ha is land area and the rest is water [Ref. 1-3]. The management of the reserve includes promoting recreational and educational activities by creating new entrances, paths and signs, as well as holding guided tours. The management also includes restoring and improving terrestrial ecosystems such as grasslands through mowing and grazing and deciduous forests through selective clearing. A wetland has been restored to promote biodiversity further [Ref. 2, 4]. The reserve was created and is managed by the City of Gothenburg, the process of creating it involved consultation of stakeholders such as land owners, government agencies and NGO's [Ref. 1]. Some local landowners disagreed with the borders of the nature reserve having an impact on their land, leading to an appeal that was ultimately denied [Ref. 5, 6]

Maya’s Farm is a small, CSA (Community Supported Agriculture) sustainable urban farm located in Phoenix, Arizona, where urban development has limited farmland availability. In 2020 alone, Phoenix lost nearly 200 acres of farmland to urban sprawl, putting farms like Maya’s at risk. The farm faced potential closure until the City of Phoenix intervened, providing funding through the Farm Preservation Program, which established the city's first urban agricultural conservation easement. Maya's Farm strives to inspire a local appreciation for sustainable food and to bring renewed value to local food systems.
The farm’s mission is to provide accessible, fresh, locally grown produce to the community while promoting awareness of healthy, sustainable food practices. Through its CSA program, members receive a weekly produce box and have opportunities to come together, honor food traditions, and share stories over locally harvested food. As a CCOF (California Certified Organic Farmers) certified organic farm, Maya’s Farm is committed to organic practices that exclude GMOs, nurture the soil, foster biodiversity, and innovate growing systems. These methods result in healthy soil and cleaner air, contribute to carbon sequestration, and support critical wildlife habitats.
To broaden educational outreach, Maya’s Farm offers several programs that promote sustainable food practices, including its CSA program, an edible classroom series, and a partnership with Arizona State University (ASU). Through this ASU partnership, students gain hands-on experience by participating in daily farm operations.
Building stronger community connections is another cornerstone of Maya's Farm’s work. The farm collaborates with local restaurants, farmers' markets, and community groups to expand its impact. Maya’s Farm, ASU, and Arizona Sustainability Alliance launched an agrivoltaics project with solar-shaded crops. (2, 9, 11, 13, 15)

In 2022, the municipality of Cagliari launched a project to revitalize Viale Trieste, one of its avenues, by redesigning its roads and pedestrian areas and adding new green spaces. The project covers approximately 1,300 meters and 36,500 square meters, and will be completed in two phases, each focusing on different sections of the avenue. With a budget of 12 million euros, funded by municipal, national, and EU resources, the aim is to transform Viale Trieste into a vibrant, accessible, and attractive space for everyone.

The renewal will introduce new green spaces and improved drainage systems to enhance soil permeability. As part of this, some trees will be relocated to other areas of the city to address root issues and improve survival rates. Dead or unstable ficus trees will be removed, while 79 new trees will be planted. Older ficus trees will be relocated to city parks, with younger ones planted along the avenue to prevent pavement damage and promote sustainability. The project also includes upgrading water supply and drainage systems to manage stormwater more effectively, reducing the risk of flooding and improving sustainability. Public lighting will be modernized, with new street lamps and dedicated lighting for pedestrian and bicycle paths to make the area safer and more welcoming after dark.

However, the community has expressed concerns about the project, citing safety issues, delays, disruptions, and poor communication from officials. There is also significant opposition to replacing the historic ficus trees, valued for their environmental and historical significance, with Chinese pear trees and younger ficus (Refs. 1, 2, 3, 4, 5, 6, 11, 16).

The City of Gothenburg's policy for park and street trees was updated in 2016 and has the overarching aim to maintain and develop the ecological, historical, social and economic values of the city's trees and tree environments. Trees are described as having ecological, historical, cultural and economic values. They can provide ecosystem services such as habitat and biodiversity, air quality improvement, flood prevention, heat mitigation, recreation and aesthetic values [Ref. 1].

The policy applies to all trees in the streets, squares, and parks within the municipality but not to natural environments such as forests at the city's edge. Further, the policy is mostly relevant for municipality employees whenever they make decisions that will affect trees or tree-covered areas, such as zoning/planning and construction projects. Other actors in the city, such as private real estate or construction companies, are not required to follow the policy but are encouraged to consider it. The policy formulates sub-goals and guidances regarding the preservation of existing trees (prioritising large and old ones), the planting of new trees, the maintenance of trees, protection during construction work and finally, the taking down of trees, including compensation measures. The policy's direct effects is an expected improved management of trees within the municipal organisation. This may have further indirect benefits in the form of increased ecosystem service provision when the policy affects other projects [Ref. 1, 2].
