Maintenance and management of urban nature

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)

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 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).

The Misheel Botanical Garden is a large park located in Ulaanbaatar, Mongolia, established in 2021 along the Tuul River. The project was carried out by "Misheel Group" LLC in cooperation with public actors and more than 100 customer organisations, within the framework of social and environmental responsibility. The project cost 2.1 billion MNT and covers 110,000 square meters of green space, which was beautified without disturbing the native vegetation. The center aims to maintain and restore the ecological balance of flora and fauna, increase the flow of the Tuul river basin by planting trees each year, and provide citizens with more leisure and recreation opportunities. The botanical garden includes a combination of green-blue infrastructure and offers the opportunity for people to relax and expand their knowledge about a healthy environment. The center features a laboratory for students of natural sciences, a basketball court, a sand volleyball court, leisure areas for the elderly and infants, a dedicated sand area, and access for strollers and people with disabilities.

Mérida city developed a Municipal Green Infrastructure Plan (Plan Municipal de Infraestructura Verde), in order to "strengthen the green infrastructure system through planning, design and implementation of urban strategies at different scales of actions and projects that contribute to enriching ecosystem services in the public and private space of the Municipality of Mérida" (Ref. 1). The plan has four axes, providing a comprehensive and transdisciplinary approach to integrating nature-based solutions into city planning and the design of public spaces in order to provide climate change adaptation and mitigation benefits (Ref. 1).
The Mérida Green Infrastructure Plan shares strong ties with a state-wide strategy, 'Arborizando Yucatán', which promotes reforestation efforts across the 106 municipalities of the state in order to "help reduce the effects of climate change, have more areas green and a better climate for the benefit of current and future generations of Yucatecans" (Refs. 3 & 4). At both the municipal and state level, the relevant administrations (Mérida City Council and the State Government, respectively) have signed an agreement (Declaration for Mérida 2050), whereby both pledged to plant at least 200,000 native trees in the City of Merida, running alongside both the Mérida Municipal Green Infrastructure Plan and the Aborising Yucatán Strategy (Ref. 2).

The Beddagana Wetland Park is located in Sri Jayawardenapura Kotte, Sri Lanka's administrative capital. The wetland park plays an important role in flood regulation and keeping the city cool during periods of extreme heat. The city is located in the Colombo district and the project contributes to the flood management goals of the Metro Colombo Urban Development Project (MCUDP). It demonstrates how a wetland can be preserved while promoting eco-tourism and improved livability in the city. The target area is located within the Sri Jayewardenapura-Kotte municipality and is a part of Parliament Lake. While focusing on the protection of the wetland habitat as a flood-retention area, the project also supports selecting investments aimed at the protection and landscaping of key areas within the target area to improve livability for local people living in and around the area, while providing access to much-needed recreational space.

Typically considered dividers of the urban space, ravines ('barrancos') which run through Guatemala City are being targeted for an overhaul of their reputation and are instead being reframed as a way to bring people and their environment together (Ref. 3). Now metamorphosed into a grassroots movement, 'Barranqueando' "wants to continue integrating the ravines with the urban environment to generate ecological, social and economic benefits for their city", where the unexplored potential of the ravines can be realised as areas to "serve as natural reserves, as nodes and paths for sustainable mobility throughout the city, as rainwater collectors, as crucial carbon sinks, as well as for purifying and cooling the air" (Ref. 3).

One of the first projects of the movement was the development of Jungla Urbana, an ecological park that brought together a ravine and the adjacent urban space, "giv[ing] residents the opportunity to wander through largely untouched nature – and experience the natural ecology of the site their city is built on", and providing an area to "...explore how the city’s unique ecosystem can be used to benefit its citizens – ecologically, socially and economically" (Ref. 3).

A rain garden has been implemented at the Fazenda Lagoa do Nado Municipal Park in Belo Horizonte. The rain garden has been created as "a solution that contributes to the runoff of rainwater, allowing the water to be filtered through vegetation and infiltrate into the soil", with this type of solution being recognised as a method which "recharge[s] the water table, increases biodiversity, improves the local microclimate and air quality" (Ref. 1). The rain garden has been created as a demonstration project within the wider INTERACT-Bio project which is led by the global Local Governments for Sustainability network, ICLEI (International Council for Local Environmental Initiatives) (Ref. 1). As summarised by President of the Municipal Parks and Zoobotany Foundation of Belo Horizonte, Sérgio Augusto Domingues, “This is an important experiment that enables solutions based on nature. The idea is that it, like other mechanisms, complements macro-drainage interventions, helping the city to be more resilient to extreme events related to climate change" (Ref. 3).
According to the Municipality of Belo Horizonte, the Multiannual Government Action Plan (PPAG) aims to implement 30 rain gardens in the municipality by 2025, each garden having an area of ​​150 square meters (Ref. 7).
