Increase green urban nature for carbon storage (wetlands, tree cover)

IKEA opened its doors in Budapest in 1990. This was the very first store in Hungary. Twelve years later, the store announced that it would install a green roof. The main purpose of the green roof was to compensate the locals for the loss of green space. The green roof was intended to create a biologically active surface that fits in aesthetically into the suburban landscape and provide a home for animals such as pollinators. The green roof, built in 2002, was covered with a Sedum carpet. In 2014, when the original Sedum vegetation died out, the green roof was completely removed. Then, during the autumn 2014 planting, four types of Sedum shoots were seeded. This was followed in the spring of 2015 by the seeding of herbaceous dicots seed mixes, which contained seeds of roughly 50 plant species. The vegetation is regularly monitored by ecologists: in 2021, more than 160 different taxa were recorded, including spontaneously occurring species. The green roof is closed, not accessible to the public, however tours are occasionally organized for professionals [3] [6] [8] [9] [10] [11].

Located in downtown Bandung, with an area of 3.8 hectares, Babakan Siliwangi (more commonly known as Baksil) has been declared The World City Forest on September 27, 2011, by the United Nations Environment Programme (UNEP). It is part of the green belt of Bandung and is a place of recreation for residents and features a canopied walking path. Declaring the forest as part of the urban green belt of the city has not been an easy task for the management team of Baksil as in 2011, there was a plan to build privately-owned multistories building at the site, which would greatly reduce the environmental quality of the area. In response to this challenge, the team initiated a series of awareness actions as well as a planting campaign to raise the profile of the forest, as well as to address several environmental challenges such as emissions reduction, noise pollution, soil degradation, and fauna and flora conservation. The intervention proved to be very successful as it established the Baksil forest as a new public space that enabled people to get to know and better appreciate their city forest. Several communities have been holding events in this area to activate the idle space, while inviting more people to interact with the forest, making it to be invaluable for the local community and the city of Bandung.

Indonesia’s peatlands are among the most vulnerable ecosystems on Earth and also have significant potential as carbon sinks (1,2). Fire risk in Sumatra's peatland areas is high due to canals that were dug for logging and plantation development (1,2). The Sumatra Merang Peatland Project was thus launched to restore the area as the massive forest fire in 2015 destroyed thousands of hectares of biodiverse tropical forest (1). This project includes restoring more than 22,900 hectares of peatland rainforest in the Merang region, located within Musi Banyuasin Province, South Sumatra in Indonesia (1,2,3). The project targets the Merang biodiversity corridor, one of the largest and deepest peat swamps in South Sumatra, which protects an area more than 3.5 times the size of Manhattan (New York City) (1,2,3). This project is a part of the Althelia Climate Fund and was implemented on the ground by Indonesian Companies named PT Global Alam Lestari (GAL) and Forest Carbon (1,2,3,4,5). The project aims and contributes to climate change mitigation and ecosystem resilience by peat rewetting and reforestation, protecting biodiversity and working with local communities to build and improve livelihoods (1,3).
The first stage of the project is considered completed and is considered to achieve positive impacts already, but it still aims to upscale certain activities until 2025 (3,4,5). The total lifetime of the project extends to 2062 (4).

Nazarbayev University (NU) launched the Green Campus (GC) project in 2016 to promote environmental sustainability (2). The GC concept is based on principles of the sustainable development and aims to focus on the greenhouse gas emissions reduction and waste management processes (1, 5). The university has established a Green Campus office, a Green Campus University Committee and the NU Green Society for the implementation of the project (2).

One of the main activities of the Green Campus is organizing tree-planting events on campus. To date, more than 1000 trees have been planted, with funds donated by university sponsors or raised via the collection and recycling of campus wastepaper [3, 4]. Additionally, the initiative also implemented a separate waste collection process for six types of waste: paper, plastic, glass, metal, batteries, and light bulbs. The collected waste is sent for recycling to selected companies [2].

Before Earth Day, NU also hosts an annual Green Week in April, to promote sustainability practices within its community. The Green Week program typically includes eco-talks by experts, workshops, garage sales, vegetarian food fairs, eco-trips, art exhibitions, and environmental movie screenings [2, 4, 5]. Climate Week, training courses, and Climate Launchpad are also part of the university's green initiatives to educate students on environmental practices [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).

Clifton Urban Forest was initiated by an individual named Shahzad Qureshi after Karachi witnessed its first “official” heat wave in 2015. More than 2000 people died in the region when temperatures reached over 120 degrees Fahrenheit in Karachi (Ref: 1,4). The major culprit for this heat wave was the ‘Urban heat Island’ effects, resulted from the congested concrete build-up and less green cover. At that time everybody started realizing the non-existence of green cover in the city is the reason behind the city being very hot. Qureshi saw a TED talk about the Miyawaki Method, a quickly growing dense urban forest and decided to give that a try. He believed that the Miyawaki Method, which promised a fast and sustainable forest within three years without using any pesticides and chemicals, could transform Karachi (Ref: 4,7).

Therefore, in December 2015, he and his team planted the first pilot forest covering about 300 square meters based on Dr Akira Miyawaki’s Methodology in a city-owned site in the Clifton area of Karachi. The area previously was used as an open dumping site. The project landscape design was developed by a German-trained landscape architect on 3 acres area and turned into an urban forest park (Ref: 6, 9). When the project became successful, they expanded the forest to the whole park, which is almost 12,000 square meters. The current project envisions increasing the green cover to restore Karachi's degraded environment by creating evergreen and sustainable forests. It targets to feature 50,000 trees, more than 50 native species, 1.2 km of nature walkways, vegetable gardening, community composting, a butterfly garden, a children's natural playground, a fruit forest, a central lake and a skywalk (Ref: 2, 4).

The created forest is self-sustaining with recycled wastewater. It has an organic vegetable garden that provides food for the community, a natural playground for kids, a lake for excess water storage, and a composting and recycling area that absorbs waste from 100 households around the park. Multiple school field trips have been arranged in the park to create awareness among the children about biodiversity and the natural ecosystem (Ref: 5, 6). Moreover, people have been actively visiting the Urban Forest and enjoying the interaction with native plants, and biodiversity and spending some peaceful time for relaxation and leisure (Ref: 9).

The project has received a lot of national and international recognition and funds from Sugi Projects, the Rotary club and crowd-sourced from various corporations and individuals (Ref: 7). Since then, Qureshi and his team have created 24 more forests in Pakistan (Ref: 5, 6).

As part of the Green Pakistan Programme (GPP), the Ministry of Environment of Pakistan initiated a plantation drive on the Margalla Hills, threatened by climate change, droughts, floods and deforestation. Margalla Hills National Park (MHNP) is a national park of Pakistan located in the capital city, Islamabad. It was established in the 1980s with a total area of about 173 square kilometres constituting Margalla Hills, Shakarparian Park, Rawal Lake and the Cultural Complex (2,5). The primary purpose of GPP was to protect the environment and revive forests, as Pakistan is a forest-deficient country having 5.01 per cent of its total area under forest cover. The park is under the supervision of the Islamabad Wildlife Management Board (IWMB) which ensures the management, maintenance and preservation of wildlife and other species in the park vicinity. The campaign was set to take place over 5 years between 2017-2022. Furthermore, as part of the same program, an awareness campaign was started to generate knowledge about plants and make Islamabad green and beautiful. Thousands of people visit the national park daily to enjoy the natural environment and healthy recreational facilities and relax by looking at the serene landscape and natural viewpoints of the city visible from the different trails of the park.

Penang is a state located in north-western Peninsular Malaysia with an area of 1,049 km2. It comprises two local authorities, Penang Island and the mainland. The former is further divided into five administrative districts which are further divided into mukims (sub-districts). Two urban mukims located on the island – George Town and Bayan Lepas – are the focus of the proposed nature-based solutions (NBS) climate adaptation programme. The programme was launched in 2022 by UN-Habitat in collaboration with the Ministry of Environment and Water (KASA) of Malaysia, Penang Island City Council (Majlis Bandaraya Pulau Pinang - MBPP), Department of Irrigation and Drainage (Jabatan Pengairan Dan Saliran - JPS) and Think City (a wholly-owned subsidiary of Khazanah Nasional Berhad (the sovereign wealth fund of the Government of Malaysia)). (Ref 1)

The implementation of the project responds to several challenges posed by climate change including heatwaves and flooding (Ref 4). The main goal of the programme is to enhance urban resilience and reduce human and ecosystem health vulnerability to climate change impacts and extreme weather events by implementing nature-based solutions (NBS) such as tree-lined streets, pocket parks, green parking spaces, green facades and rooftops, urban agriculture and blue-green corridors to reduce surface temperatures and stormwater runoff, as well as to increase social resilience and build institutional capacity (Ref 1, 3).

As early as 2010, the then authorities of Malaysia announced plans to transform certain Malaysian cities into green cities. Motivations behind these actions focused on addressing environmental challenges such as carbon emissions, high temperatures, and a reconnection with nature. One of the cities where green ideas were to be implemented was Putrajaya, located 25 km south of Kuala Lumpur (Ref 3). As this is a very complex project, the initiative was being led by the Perbadanan Putrajaya (PPJ), which is a local authority that administers the Federal Territory of Putrajaya and is under the Federal Territories Ministry of Malaysia. In transforming Putrajaya into a green city, PPJ undertook 38% of its area to be developed into parks, lakes, and wetlands while the rest is reserved for government offices, commercial and residential development, public utilities, and amenities (Ref 1). Green actions involved the creation of a wetland (the largest constructed freshwater in Southeast Asia), the implementation of an Urban Farming Programme and Rooftop Farming programmes, as well as large-scale tree planting (Ref 2, 3). PPJ aims to transform Putrajaya into a green city by 2025 including Putrajaya Inter-Parks Ride, Pedestrian Walkways and Bicycle Lanes. Putrajaya’s efforts in the implementation of these green initiatives have received numerous awards & recognitions (Ref 3).

Iloilo River Esplanade is a promenade and linear park along the Iloilo River, created as part of the Iloilo River Rehabilitation Project. It is the largest linear park in the Philippines and was designed by the landscape architect Paulo Alcazaren. The esplanade is one of a kind in the country that aims to foster biodiversity, store carbon by mangroves and provide protection from possible flood damages. Furthermore, the project aspires to build a lifestyle hub for the locals and promotes educational eco-tourism. The site was an existing dike road devoid of shade and originally built just as a flood control measure. The redesign has showcased its effect on public amenities, received several recognitions and has become a magnet for tourists in this city. [1, 3, 6, 7]
