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 Bakhawan Eco-Park is a 220-hectare mangrove forest located in Kalibo, Aklan province, Philippines, that started as a reforestation project in 1990. It was a joint project of the local government and a non-government organization, Kalibo Save the Mangroves Association (KASAMA), with the aim of reforesting the muddy shoreline of New Buswang district to protect the community from floods and storm surges [1,2]. Aside from preventing floods, the eco-park also provides locals with livelihood opportunities, mitigates the effects of climate change, and serves as a habitat for various mangrove tree species, birds, and marine life [1,2]. The project's success is largely attributed to the active involvement and support of the local community, with some families playing an integral role in the reforestation program. [2] Notably, the involvement of local women in the NBS initiative has contributed to the success of mangrove conservation. Some women have also taken on the task of policing the mangroves to prevent illegal tree-cutting by trespassers [4]. Today, the eco-park is acknowledged as one of the most successful mangrove reforestation project in the Philippines [1]

To improve the ecological and living environment for the residents, Vietnam National University in Ho Chi Minh City (VNU-HCM) inaugurated a project, "For a Green Dormitory" in September, 2022. The project is a tree planting activity sponsored by the program "One million urban green trees" (MTIC) by Green Viet Water Biodiversity Conservation Center (GreenViet), through the Conservation Fund project. The aim of the green dormitory project was to promote the planting of different species of trees to improve the ecological and living environment for more than 40,000 students staying at the centre. More than 1000 trees such as Pink trumpet, Black Star, Oil, and Camphor have been planted at planned points at the dormitory (1). The initial goal was to plant a total of 5,250 trees from September 2022 to March 2023 and included a series of greening activities of mass organizations at the dormitory campus of the Vietnam National University. So far, more than 1000 students, 200 lecturers, the dormitory manager of VNU-HCM and more than 50 members of Dang Gia Trang Manufacturing, Trading and Service Co., Ltd, participated in the project (1). In addition to this, the project also initiated an exchange program through which plastic waste was exchanged to receive green trees, encouraging awareness among officials, employees and boarding students (2).

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)

Sky Park One Islamabad is an innovative high-rise apartment building project, located in the heart of the prestigious Gulberg Greens in Islamabad (2). The building has been designed with a unique concept that features a rooftop level garden with ample plantation.

Rooftop garden are still very rare in Pakistan (5) and as such, the project provides an example for the green vertical housing in Pakistan with a focus on energy efficiency (1).

Raipur city is known as the seventh-most polluted city in the world (2, 3, 4). In response to the escalating problem of air pollution and its public health effects, the state of Chhattisgarh in India has envisioned the creation of a verdant and healthy natural space for urban inhabitants in the heart of Raipur - the Oxi-zone (3).This project acts as the 'Breathing lungs for Raipur' (1, 2). Approximately 19 acres of land were allocated to create an ‘oxy-zone’, including the demolition of buildings to plant trees in their place (1, 2, 4). Inspired by the iconic Central Park of New York City, and suggested by a local citizen group, the Oxi-zone aims to transform this area into a thriving habitat for diverse species of trees and plants, which will also provide water bodies to replenish the groundwater in the vicinity (2, 3, 4). In summary, this project is an integrated green space, enabling residents to relax, meditate and exercise within the “shadow of nature” (3, 4).

As an industrial development practice that involves a symbiotic connection between materials, energy, natural systems and local communities, the concept of green industry has become a point of focus for a factory in Rangapur, Karupannya Rangpur Ltd., designed by Architect Bayejid Mahbub Khondker and his team. The factory has become a pioneering example in the "green industry" initiatives in Bangladesh (2).
The factory has a green façade of climbing plants, as well as a green rooftop and integrated green elements, designed specifically to incorporate a once extinct industry, the Shataranji (weaving style). The intervention was designed to respond to human and enviornmental needs (2,7). From a human perspective, the intervention responds by improving work conditions for the workers by introducing green spaces that help with local temperatures and relaxation. From an environmental perspective, the project responds to challenges related to energy efficency (3,4).
The factory architecture incorporates cultural and indigenous knowledge with the utilization of natural light, wind, water, and flora while maximizing the use of natural elements and the idea of "Reuse and Recycle." The factory's roof features the Nandini Park, where employees can relax and eat lunch. The Nandini Park is surrounded by flowering plants and vegetation. (1, 2, 4, 6)

Uuliin Nuur (Mountain Lake or Green Lake) is a community park located in the ger district area known as Denjin Myanga of Ulaanbaatar city. The Ger district is a term commonly used in Mongolia to refer to a type of settlement located on the outskirts of the country's capital city and characterized by traditional Mongolian gers, or yurts. The area was once a quarry for the city’s construction during the socialist regime (from 1946 to the late 1960s) and was turned into a dumping ground after its closure. In 2009, a private citizen, Ulziitogtokh Sodnomsenge, gained approval to develop Uuliin Nuur. He cleaned up the area and used his savings to turn the former dumpsite into a green garden in the middle of ger areas to create a healthy, green, public space, especially for children living in the area. He opened an ice rink in the winter of 2012 and officially opened the Uuliin Nuur park in May 2014. From 2013 to 2019, approximately 1000 trees and shrubs were planted in this park during the spring and autumn. The trees were planted by the founder of the project by locals and foreign visitors as memorial trees. Over the years, the park was equipped with various community facilities to support social interaction and educational purposes. Uuliin Nuur is one of the few public places launched and developed by an individual. It showcases how abandoned places can be transformed into valuable places and how the local community's attitudes and awareness can change. (Ref. 1, 3, 4)

The northern part of Thane Creek in Navi Mumbai was declared a 'Protected Area' in 2015 by the Maharashtra Government (1,2,4). As the Central Asian Migratory Flyway (CAMF) ecosystem, it is occupied by a large number of wading birds, especially Lesser Flamingos and Greater Flamingos (1,2). Recently, a Management Plan has been proposed to guide the sustainable management of the 'Thane Creek Flamingo Sanctuary (TCFS)' (1).
The Management Plan (2020-2030), proposed by the Mumbai Mangrove Conservation Unit (MMCU) proposed implementation plans for the conservation of Flamingo species, mangrove management, eco-tourism, education and awareness raising, as well as participatory decision-making (1).
Thane Creek harbours rich biodiversity and spreads over an area of 1690ha (896ha of mangroves and 794ha of adjacent creek water body) (1,2,3). Also, it is located right amidst a mega-city, being crucial to conserving this unique natural environment with its eclectic mix of mangroves, mudflats and threatened bird species (1,2).
