Pirojshanagar Township is an industrial and residential establishment of the company Godrej & Boyce Mfg. Co Ltd (G&B), located in the Vikhroli suburb of Mumbai city along Thane creek, with diverse natural and human-made habitats (1,2). Of the 16 km2 area of the Township, approximately 12 km2 is occupied by the mangrove ecosystem and its associated habitats (1,2). Upon recognizing the importance of this ecosystem, G&B decided to prioritize the conservation of the mangroves that grew along the banks of the newly acquired land (along the Thane Creek west bank) (1,2). Pirojshanagar, with its biodiverse mangrove forest, is sandwiched between two solid waste dumping grounds of the Brihanmumbai Municipal Corporation (BMC), which only increases its importance in the landscape and makes it a green oasis that acts as a carbon sink (1). It was a research-based project and the first successful mangrove conservation project in Mumbai, now serving as the Mumbai Metropolitan's green lung (1,2).

Benchakitti Forest Park was created as the extension of the existing Benchakitti Water Park, which is located near the central business district of Bangkok, Thailand. The Forest Park is built in an old Thai Tobacco Factory area. The main concept of the park is to bring the forest into the city and support urban biodiversity while offering leisure activities for the people. The main features in this project include constructed wetlands, nature learning and exercise trails (for running and bicycling), a learning centre, an urban farming area and multipurpose open space for gathering and event activities. Benchakitti Forest Park can be divided into 2 parts. The first part is a green outdoor area including the wetlands, all trails and an outdoor amphitheatre. This first part was completed and open to the public in 2022. The second part is the renovation of buildings into museums and the creation of an urban farm and other facilities associated with the building. This second part is still under construction.

This project aims to create a Butterfly corridor through the city of New Delhi by connecting local parks, residential gardens, biodiversity parks, and major forest areas (Ref 1, 2). For this, various locations, mainly maintained by citizens, are developed as habitats for the butterflies by planting various kinds of host plants which can be used to lay eggs. Overall, about 100 butterfly corridors are planned to be developed over time (Ref 3). The project is initiated by the Conservation Education Centre (CEC), a Delhi-based faction of the Bombay Natural History Society. With the help of CEC, community custodians of the gardens are trained to develop butterfly parks. A number of public and private land areas have now been designed as butterfly corridors throughout the city (Ref 1).
An underlying aim of the project is to allow butterflies to travel across locations, thus allowing genetic diversity among populations (Ref 1). The project has also helped educate the community about the importance of maintaining a healthy butterfly population. Through the organization of Butterfly month in September every year, citizens and, especially young kids, are encouraged to learn about butterflies through butterfly walks, counting, and photography contests, among other activities (Ref 1, 5).

The Greater Iqbal Park is one of Lahore's largest and most beautiful parks and is located in the suburbs of the Walled City of Lahore. The park was built in 1971 and is named after the national poet of Pakistan, Allama Iqbal (7). The redevelopment of Greater Iqbal Park was approved in 2015 by the Government of Punjab. The project was developed under the supervision of the Parks and Horticulture Authority (PHA). The landscape plan was designed by the joint collaboration of national (NESPAK) and international (Sites International) consultants. The on-ground earthwork and construction were carried out by Habib Construction Services, a Pakistan-based engineering construction company (1, 5, 4, 11). The design idea of the project focused on revamping the area to create a welcoming environment in the environs of the city’s densely populated areas (6).

The project aimed to renovate and preserve Minar-i-Pakistan Monument and expand the area of the park to 125 acres. It features elaborate walkways and manicured gardens with state-of-the-art landscaping to boost tourism opportunities The project envisioned enhancing the cultural heritage by creating green spaces with various species of plants and trees along the park to ensure efficient facilities for the users. The 125-acre green oasis is surrounded almost entirely by the old city of Lahore (1, 3, 4, 11, 12).

The park was inaugurated in December 2016 with state-of-the-art facilities for users, whereas the overall project including the development of the National Museum was completed in 2018. The park has been designed in a manner that its aerial view resembles the national symbol of the star and the crescent. (3,11)

Vietnam's capital, Hanoi, is the second largest city in the country and is one of the most vulnerable to climate change. The city is located on the western bank of the Red River, the principal river of northern Vietnam. Throughout the centuries authorities in Hanoi built dykes to protect the city from the instability of the Red River. Though these dykes were built at a high altitude, the floods became more intense due to the huge amount of alluvium that rests in the middle of the river and that could not continue to consolidate on the banks and making water levels higher and more dangerous. Furthermore, outside the dykes, in the riverine zones (which play a role as green corridors to connect the city and the river) economically disadvantaged people built settlements contributing to soil erosion (caused by illegal construction and excessive sand exploitation), subpar soil quality, and poor waste management. (1,2)

The Red River Zoning Plan (RRZP) came as a solution to address the issues before mentioned and has been promoted by the Hanoi People’s Committee. The plan is encompassing an area of about 11,000 hectares in 13 districts. The plan was approved by the Hanoi People's Committee in March 2022 at a size of 1/5000 section from Hong Ha Bridge to Me So Bridge. (1,4)

According to the concept, a 40-kilometre-long new metropolitan area would be created on both banks of the Red River. This urban space would be a flood drainage area for downtown. It will be designed with a green landscape including public spaces for cultural and tourism purposes. For this, the city would invest in a network of transport and technical infrastructure to bolster connectivity in terms of roads and waterways with neighbouring areas. Particularly, the RRZP is building three types of new parks near the riverbanks, including a nature conservation park, an agricultural park, and an urban park to improve climate change adaptation and bring more natural elements to the city.

Neknampur Lake, also known as Ibrahim Bagh Cheruvu, located in Hyderabad, Telangana State of India, has historical importance and was part of a water reservoir network for irrigation and drinking as well as an inalienable part of the rural ecology of the village (1,2). Due to urbanization, the lake underwent drastic changes in ecology, land use and management in the past decade. Scientific investigations conducted by the Telangana State Biodiversity Board on Neknampur Lake highlighted that the water body was full of sludge and extremely eutrophicated, showing elevated algal growth (2). This was mainly because of the unabated entry of sewage and other waste over an extended period into the lake (1,2). In June 2016, The NGO named 'Dhruvansh' decided to adopt Neknampur Lake and thus began a series of interventions that incorporated bioremediation and phytoremediation techniques, regular cleanup drives of plastic removal and recycling campaigns into a restoration plan for the lake (1,2). With the support of the government institutions, 'Dhruvansh' began the revival of the lake across two phases: (1) the revival of the lake periphery and the lake body, followed by (2) the revival of the lake ecosystem (1,2). The ecological restoration of Neknampur Lake has improved the ecological services it provides and restores the glory of this historically significant lake, now known as a biodiversity hotspot (1,2,3,4).

Lahore University of Management Sciences (LUMS) is a private research university located in the main residential area of Lahore City and is spread over a 100-acre area and hosts various plant and bird species. The Life Sciences Department of LUMS collaborated with the Botany Department at the Government College University to plant some rare species of endangered trees at LUMS. The project aims to preserve the ecosystem on the LUMS campus and develop an inventory of plants and animals commonly found on the campus. Taxonomic expertise and the modern science of DNA sequencing are used in the analysis and identification of plants. Additionally, LUMS aims to be the first University in Pakistan to set up a national biosurveillance system that would track biodiversity at all documented sites with their GPS coordinates across the whole campus. It envisions creating knowledge and awareness about the importance of the diverse biodiversity found on campus. It will enhance the effective management of present resources to preserve them for future generations. These findings may potentially serve numerous disciplines from other departments and also increase information and effective management of wildlife on campus. (Ref: 1, 2, 3)

The Upper Kinta River Basin covers an area of about 31,470 hectares above Ipoh City, and it is the main water catchment resource for the residents of the city and its surrounding areas. The Kinta river basin is now threatened by land erosion, land development, improper sewage treatment and irresponsible waste discharges (Ref 1). In 2021, a pilot project was implemented near the city of Ipoh along the SimpangPulai Highway and experimented with river bio-engineering techniques to reduce soil erosion and subsequently prevent sedimentation downstream (Ref 3). The pilot site was established as part of the Mainstreaming Biodiversity Conservation into River Management project, which focused on applying nature-based solutions for mainstreaming biodiversity into riverine landscape planning and watershed management in Malaysia. To provide seedlings for the bio-engineering project and also other related initiatives, a nursery was established in the indigenous Pawong Orang Asli Village. The nursery also provided additional income for communities (Ref 4). The pilot was developed with the expectation to be upscaled and replicated in other parts of the UKB, especially along the SimpangPulai Highway. (Ref. 6)

The International Cultural Garden Park (IC Park) is a comprehensive, private-sector-led, green development project in Yarmag, Ulaanbaatar, Mongolia. Initiated in 2021 by the Ikh Uilsiin Ereld Group LLC on its own property land as part of its social responsibility, the planned area covers a 35 hectares (86 acres) site. First, an international design competition was announced to plan the project. As a result of this competition, a contemporary park concept was developed for Ulaanbaatar's New Center to convey an international concept, with designs of significant cultural and historical elements from over ten different nations. The IC Park will also serve as a venue for a variety of international events, including conferences, sporting competitions, cultural festivals, and more. Green technology is being used with particular attention throughout the park's construction, and more than 90 species of trees and about 50 species of natural perennials growing in Mongolia are planned to be planted with the cooperation of professional tree planting and gardening organizations, specialists, researchers, and scientists. As of today, more than 7,000 trees have been planted in the project area, and professional personnel are diligently working on their care and pruning. The project is expected to reduce the negative consequences of global warming, create a greener environment, and secure long-term employment. (Ref. 1, 2, 4, 7)

The International Institute of Rural Reconstruction (IIRR) Myanmar and its local collaborative organizations developed a community garden at Inn Dein village to ensure access to diverse and safe food amidst the current internal crisis in Myanmar. The community garden is a part of the wider research project “Climate-smart villages as platforms for resilience building, women empowerment, equity, and sustainable food systems”, funded by the International Development Research Centre (IDRC). The expected outcomes are to benefit over 4,200 internally displaced persons (IDP) (due to COVID-19 and internal conflict) in Inn Dein and the Yangon Monastery Camp in Nyaungshwe. The community garden was established in the close vicinity of the Internally Displaced People (IDP) camp. The garden area is about 1.5 acres and rented for three seasons from the owner. Saplings were supplied for agroforestry purposes and a community support fund has also been provided for income generation and livelihood activities. Sprinkler irrigation has been installed to cover the whole land area, and 20 types of crops, including several legumes crops and vegetables such as mustard, radish, carrot, coriander, okras, eggplant and pumpkin are being cultivated. This project is particularly important in the current situation "[because of the lack of opportunities to direct support to IDP camps and the risky situation in food supplies, access to food and nutrition for IDPs is critically important." This project benefits both addressing food insecurity and increasing green space in the neighbourhood of the IDP camps. (Ref 1).
