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)

To address the mismanagement and illegal deforestation in the Changa Manga forest, the Punjab Government in Pakistan initiated strict actions with the help of the Forest Department between 2014 and 2017. Activities included planting new trees and taking action against illegal deforestation. Over the years, mismanagement and illegal deforestation decreased this woodland by 75% (measured in 2012) (2). The Government of Punjab approved the “Afforestation in Blank Areas in Changa Manga Plantation” project for the duration of three years from 2014 to 2017 aimed at the afforestation of a total area of 200 acres on flow irrigation during 2014-15 and maintenance of afforestation during the two subsequent years (2015-17) (4). Changa Manga Forest is one of the world’s oldest hand-planted forests, dating back to 1866 in Chunian City. It spreads over about 5065 hectares and hosts a wide variety of flora and fauna. The forest is home to 14 species of mammals, 50 species of birds, six species of reptiles, two species of amphibians, and 27 species of insects (1). Some exquisite tree families, such as Sheesham (rosewood). white mulberry and Kikar trees are found in this woodland (2). It also includes a wildlife preserve, which was launched in 2005 by the World Wildlife Fund (WWF) Pakistan to protect white-backed vultures and ensure their captive breeding in the forest (3). Currently, Pakistan is losing forests at thrice the rate of the other South Asian countries. One of the major benefits of the Changa Manga Forest afforestation project was that it increased honey production by 70% in the different areas of the forest park (5).

Balili River, situated in the province of Benguet, is among the many urban rivers in the Philippines that suffer from severe pollution due to various human activities. Indiscriminate dumping of waste in almost all of its 23 tributaries is a significant contributor to the pollution. Despite this, the river remains a critical source of irrigation for farmers in La Trinidad who primarily grow strawberry and salad crops in the valley. However, the use of contaminated water from the river poses a direct threat to the food safety of consumers of these crops. Moreover, during the summer, the black water of the Balili River is a constant eyesore in the community. To address these environmental concerns, a pilot study was conducted aimed at exploring treatment options for the polluted water in Balili River. The study focused on assessing the use of local plants to restore biodiversity, conserve wildlife habitats, and test the phytoremediation potential of local macrophytes. The pilot area was established within the Organic Farm of Benguet State University near the main stream of the Balili river. The study set up two types of constructed wetlands (CW), a surface flow CW for floating plants and a horizontal subsurface flow CW for emergent plants. The results of the pilot study suggest that constructed wetlands could be an effective solution for cleaning up the Balili River. The implementation of constructed wetlands in Balili River can not only improve the water quality but also benefit the local community and ecosystem. [1,2]

The United Nations High Commissioner for Refugees (UNHCR) and its partners collaborated in 2018 to develop an ecosystem restoration project in the Rohingya Camps of Ukhiya, near Cox's Bazar. The main objective of this project was to mitigate the increased risk of landslides, slope instability, and flooding caused by flash floods and the vicinity of the Bakkhali River. The intervention included the planting of quickly growing native trees, shrubs, and grass species. Additionally, the project encompassed other measures such as vegetable cultivation on stream beds, biological soil stabilization methods, and plant-based wastewater treatments. To ensure the sustainability of the project, a network of future practitioners from the Bangladeshi and Rohingya communities was created. Moreover, environmental education and awareness activities were undertaken to complement the efforts of the project, with a particular focus on engaging young people from both the host and refugee communities to maximize its impact. The area where the project was implemented has been significantly affected by land and forest degradation over the last few decades, which has been exacerbated since the arrival of Rohingya refugees in 2017. Therefore, the project also involved other stakeholders such as the International Center for Conservation of Nature (IUCN), the Danish Refugee Council, the World Food Programme, the International Organization for Migration, and the Bangladesh government, each contributing in various capacities to achieve the project's objectives.

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 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]

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. It aims to enhance the quality of life for the residents and provide them with facilities for relaxation within the apartment building (3). The rooftop garden spans an area of 9 Kanals (about 650sq.m) and features 7 green courtyards in the building. The 152 residential apartments are all connected to the joint courtyards (2, 3). 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).

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)

The Urban Farm Office building, is a concrete-framed structure covered in a "vertical farm" of vegetables, fruits and herbs. The building was constructed by the Vietnamese architectural firm Vo Trong Nghia (VTN) Architects in early 2022 as its own headquarters in Ho Chi Minh City. It aims to promote the production of safe food while reintroducing green space to the city with a façade covered in vegetation. Furthermore, the project also seeks to address the absence of green space that contributes to a number of socioeconomic issues, including air pollution, flooding, and the heat island effect. VTN Architects' idea for the Urban Farming Office includes the area of space-efficient food production in cities through vertical urban farming in addition to the core objective of restoring vegetation to urban structures.
