Health and well-being (SDG 3)

The Rajakori lake rejuvenation project aimed at reviving an existing lake using a natural and sustainable treatment system, the "Scientific Wetland with Active Biodigester (SWAB)". SWAB technology uses a two-step process involving (i) a sedimentation tank equipped with a biodigester and (ii) a constructed wetland system. The untreated sewage waste is passed through this two-step process that uses microbes and plants to reduce pollutant levels. The project also involved redeveloping the public space around the lake for community use (Ref 1,2). Before 2017, the lake was overfilled with sewage and waste from nearby neighbourhoods due to a lack of proper sewage management. Initiated by the Delhi Government, the project aimed at using low-cost natural methods rather than conventional techniques involving concretized bases and chemicals to treat water (Ref 1, 4). Due to its success and cost-effectiveness, this project now serves as an excellent example for other projects within Delhi (Ref 5).

A low-rise building located within Prestige University's existing 32-acre campus in Indore will feature an entirely walkable, stepped green roof. The green roof is planned to be punctuated with courtyards for temperature regulation and accessible to its users (university staff, students and other visitors etc.) from the ground level (1,2). It is designed and implemented by 'Sanjay Puri Architects', Architecture Consultancy based in Mumbai (1,2,6). This building is planned to be used for administration offices, an auditorium, lecture halls, and a library and cafeteria (1,2,3). The green roof mainly serves as a space for recreational activities for the users. The terraces will also include different-sized open-air sections, providing the building's interior with natural ventilation (2,4,5). This project truly blends with the traditional Indian Architecture approach in an innovative and modern way (4,5) and targets problems related to central India's oppressive heat (1,2,4).
Despite the initial target completion date of June 2022 (9), the construction phase of the project has not yet been finalized. The responsible architecture firm anticipates the completion date within the forthcoming months. This information was disclosed in January 2023 (10).

The Ecological Education Center (EEC) is a nationally recognized institution committed to promoting awareness and sustainability through its environmental education programs in Mongolia. As the only organization in the country dedicated to providing such programs, the EEC operates under the National University of Mongolia (NUM) and was founded in 1957 as the "Central Station of Young Naturalists". With over 60 years of experience in environmental education, the EEC offers its programs not only to NUM students but also to children of varying ages. Since 2011, the center has developed and introduced various cognitive-based environmental training programs, providing visitors with interactive learning opportunities that takes them through different learning stations. The EEC has several facilities to support the learning experience, including a nature experience garden, a greenhouse, and a small zoological museum. The nature experience garden is continuously enriched with new tree species each year, and as a result, it is now home to over 3500 trees and bushes of 30 different species. In addition to its educational programs, the EEC also provides advice on gardening and plant care to further promote environmental sustainability. (Ref. 1, 2, 3)

In 2008, Mahidol University in Thailand announced its revised five-year Green Campus master plan titled 'A Promised Place to Live and Learn with Nature' for its main Salaya Campus. The scheme aimed to promote a green conscience and lifestyle for its students and faculty through sustainable campus developments that consider social and environmental aspects. The university's objectives were to achieve energy conservation, environmental sustainability, and social cohesion and well-being. The main features of the master plan included the creation and maintenance of green open spaces covering at least 70% of the campus premises, optimization of land use, transformation of infrastructure to encourage cycling, creation of outdoor learning, recreational and research areas, and enhancement of local biodiversity. The master plan also covered guidelines and targets for energy consumption, waste, and water management in the campus buildings. The Siri Ruckhachati Nature Park, the university's arboretum, was also redesigned with green and blue areas playing a role in flood management. Following the 'Green Campus' master plan, Mahidol University developed its existing mission further and became an 'Eco University' in 2012 and a 'Sustainable University' in 2021. These two missions focus primarily on reducing energy consumption and waste management.

The new office building of the Council of Engineers is located on one of the busiest streets of Bangkok, Thailand. The building aims to combine new engineering technology with aesthetic and function, while maximizing green area and promoting sustainability. The building's terraced green area lead the people up to the entrance on second floor and continue up to the sky garden on the forth floor. The main features of the garden are lush fauna with tree and shrub species, planters, multi-purpose open spaces and bio-filtration system that use plants to filter and divert rainwater. The project aims to acquire the platinum TREES building rating (a green building certificate in Thailand) and it is in the process of applying for the certificate. (Ref. 1,2,3,5)

The Kota Damansara Community Forest Reserve is a forest located 10 km west of Kuala Lumpur in the state of Selangor and is the oldest managed forest reserve in Peninsular Malaysia. As the reserve was threatened over the years by plans for clearing and housing development, the community located in the township close to the forest sprang into action to salvage the forest. As early as 2003 an organization called Friends of Kota Damansara was formed to lead a diverse group of concerned individuals, organisations and communities to rally together to vocally defend the forest (2, 3). Efforts to protect and conserve the forest focused on a series of activities such as the development of a biodiversity management plan, awareness-raising activities, educational activities, building capacity activities, and the creation of an ethnobotanical garden to showcase Temuan (local indigenous people) knowledge of plants (1). These efforts were funded with the help of the UN's GEF's Small Grants Programme and led to the reserve being officially gazetted as of 18 February 2010 (Sel GN 398/2010) and being classified as amenity forest, education forest and research forest, making up 3% of land area in the state of Selangor (1, 2). Nowadays, the Kota Damansara Community Forest Reserve Trails is a popular weekend destination for mountain bikers, trail runners and casual hikers (3). Furthermore, the KDCFP has become much more accessible and utilizable by visitors from various categories of societies, besides researchers discovering and documenting a number of species of flora and fauna unique or endemic to the park (1).

The Community Garden Project was proposed in 2018 by Samyuktha Kannan (a resident of Chennai City) to the Resident Welfare Association (RWA), which is a non-governmental organization (NGO) of Kasturba Nagar (1,2,3). The RWA uses the community hall of a public park of Kasturba Nagar to host meetings and community events, but the area was surrounded by open dry land and an unmanaged field (1,2). This open area surrounding the community hall was then assigned to develop a community garden of 1500 square feet (1,2,3). This project aimed to serve as a shared garden place to bring along residents of all age groups to enjoy gardening and simultaneously create opportunities to learn and share knowledge through social engagement and reconnect with nature (1,2). Although implemented and completed in 2019, the project still continues to contribute towards sustainability through further development and introduction of eco-friendly elements and activities, as well as the involvement of various stakeholders for support (3,4).

In 2005, a constructed wetland was established in Barangay Villareal, Bayawan City in order to improve a peri-urban settlement and promote domestic wastewater treatment with reed beds. The wetland covers an area of 2680 square metres and comprises two reed beds, with the first bed utilizing perforated pipes beneath a sand and gravel substrate for vertical flow filtering, and the second bed utilizing horizontal flow for biological filtering. The roots of the Phragmites karka reeds, which are used in the system, act as a natural filter, removing microorganisms and pollutants. The treated effluent is reused for various purposes, such as watering plants, firefighting, and irrigating ornamental plants and agricultural crops. The overarching objective of the initiative is to safeguard coastal waters from pollution caused by domestic wastewater and enhance residents' quality of life by providing safe sanitation and wastewater treatment facilities. Furthermore, the initiative seeks to showcase the effectiveness of constructed wetlands, encourage the use of locally available reeds for wastewater treatment, and conserve water and nutrients by reusing treated wastewater.

The "Urban Forest" project focused on the establishment of the Mongolian-Korean Friendship Forest on a 40-hectare land in Dambadarjaa, Sukhbaatar district of the capital city, Ulaanbaatar. Previously known as the Forest Research and Development Center Arboretum Park, this area has a river running through it. The project, with a total cost of over 8 million EUR, was designed specifically to reduce air pollution in the capital, to create a healthy eco-environment for Ulaanbaatar residents to spend their leisure time and to raise awareness of the importance of forests and the benefits of trees in Mongolia. In total, 55,000 trees and shrubs of 36 different species were planted so far and the park boasts five different types of coniferous trees that thrive in Mongolia, including larch, pine, abies, cedar, and spruce, as well as deciduous trees such as birch, aspen, willow, lilac, and maple. The Urban Forest park also includes several facilities, such as a visitor information center, a playground, sport facilities, a natural arboretum and a ground fountain. The park will be operational and accessible to the public in 2023. The project was implemented between 2017 and 2022, as the second phase of the Korea-Mongolia Greenbelt Reforestation Initiative jointly developed by the Mongolian Ministry of Environment and Tourism (MET) and the Korea Forest Service (KFS). The Green Belt initiative was created with the overall aims to mitigate desertification, combat climate change, and reduce yellow dust and sandstorms in Mongolia.

The National Garden Park is the largest park in Ulaanbaatar and the only park of its kind in the capital city of Mongolia, offering multiple environmental services, recreational and commercial functions. Currently, the park extends to 183 hectares, covering 23% of the total green construction in the city, and stretches from the northeastern part of the Marshall Bridge to the Uliastai Bridge in the Bayanzurkh district. In the long term, the park is planned to be extended to have a total area of 973 and to have 1.200.000 trees planted within the “One Million to One Billion” afforestation program. The park offers a range of recreational facilities and services for citizens, including bicycle and pedestrian areas, specialized sports areas and children's playgrounds. It also houses trade and service organizations. As a result, the park has become a popular recreational area for the citizens of the capital and is the most visited urban park in Ulaanbaatar. During the summer, it attracts an estimated 12-15 thousand visitors a day, and during the winter, it sees 6-9 thousand visitors a day. The National Garden park was officially established in 2009 with the aim of protecting the Tuul River Basin's drinking water source, reducing air pollution, and increasing green space to create a healthy eco-environment and providing recreational opportunities for the public. In 2016, the National Garden Park was designated as a local property budgetary enterprise with defined primary functions, management structure, control, and rights under the administration of the Assembly of Citizens' Representatives. The park currently employs 113 staff members (as of 2021). (Ref. 1. and 4)
