Flood protection

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).

Asia is one of the fastest economic growing regions and so are many cities on the Asian continent. Economic growth brings forward many challenges including intensive urban development, loss of natural features, increased urbanization, and high levels of air pollution, just to name a few. One of these cities is Ho Chi Minh where it was assessed that only 0,25% of its area is covered with vegetation, and in addition to this, there is traffic congestion and air pollution (3).
In an effort to rectify some of these transgressions, a private initiative developed a house called the House of Trees, located in Tan Binh district, one of the most densely populated residential areas in Ho Chi Minh City, where many small houses are crowded together (2).
The green features of the house include five roofs that function as gardens thanks to a layer of earth substratum, from which tall tropical trees grow (3). The aim of the project is to bring green space back into the city, accommodating high-density dwellings with big tropical trees. Five concrete boxes are designed as "pots" to plant trees on their tops. With a thick soil layer, these pots also function as storm-water basins for detention and retention, hence contributing to reducing the risk of flooding in the city. The project has been conducted by Vo Trong Nghia Architects, a leading Vietnamese firm in building green architecture in urban Vietnam. (1)

As an archipelagic state, Indonesia consists of 18,000 islands and 18,000 km of coastline, which is inhabited by more than 60% of the Indonesian population. Its geographical position exposes the island country to several climate change challenges, ranging from an increase in high temperature to a sea level rise and severe floods. One of the cities affected by flash floods, flooding, and landslides is Pekalongan City, crossed by 7 rivers and home to approx. 300,000 people. Inundations can reach 50-100 cm in many communities, causing distress, evacuations, and severe damage to infrastructure and food security as well as loss of income for the inhabitants that work in the fisheries sector, in the Batik industry (the process of traditionally dyeing fabric, performed on cotton and silk using a resist technique) or in paddy rice farming. (1)

Responding to the climate risks became of utter importance to the municipality of Pekalongan City. To help the Municipal Government of Pekalongan City to overcome the problem caused by climate change, Kemitraan (Partnership for Governance Reform in Indonesia), an implementing and advocacy NGO developed the project on Safekeeping-Surviving-Sustaining towards Resilience, a 3S Approach. The aim was to Build Coastal City Resilience to Climate Change Impacts and Natural Disasters in Pekalongan City, Central Java Province. This was approved on 29 October 2020 and is currently entering its implementation phase. The project will focus on building resilience to climate change impacts with interventions of hard and soft nature. More precisely, the project aims to build capacity and resilience through training, mangrove ecosystem restoration and enhancement of coastal protection, and development of a Local Climate Adaptation Action Plan and implementation of climate-smart actions (1,2). The project aims to reach these goals by employing a collaborative and participatory approach that is locally driven and involves those most at risk. The program is expected to end in April 2023 (1).

In order to prevent the damage to mangrove forests that occurred over the last few decades or more, a project was started in the Penang region aiming to raise public awareness regarding the importance of mangroves for their continued conservation and protection through active community participation (community resilience) (1). The project closely relates to the GEF Focal Area on Biodiversity Conservation operational programme (OP) 2 on Coastal, Marine and Fresh Water Ecosystems and is led by the Penang Inshore Fisherman Welfare Association (PIFWA). The project aimed to regenerate mangrove forests by planting up to 11,000 saplings in order to rehabilitate the once degraded mangroves as they are able to ultimately improve the wetland ecosystem and its biodiversity and thus sustain the livelihood of fisher communities (1).
Mangrove forests are an important part of the Malaysian coastline. Besides their contributions to the biodiversity of the Malaysian coast, mangroves also help greatly with protecting the coastal strip from erosion and providing a means of living for the communities located close to the forests. Stabilising the shoreline and reducing soil erosion, mangroves are also home to myriad species of plants and animals, they provide timber and non-timber forest products, and they support fisheries (1,2). Due to their importance, their disappearance is greatly noticed. From 2000, within a period of 15 years, 25,500 hectares of mangrove forests disappeared, mostly due to industrial-scale logging, clearance for shrimp farming, tourism or firewood (5).

Jin wellbeing is a senior-oriented lifestyle complex in Bangkok, Thailand, which comprises residences, commercial units and hospitals. The first phase of the development has been completed in 2020. This phase included five residential buildings with senior hospitals, wellness centres and green spaces that cover over 40% of the site. The project aims to create a sustainable living environment while enhancing both the physical and mental health of the people through nature with the “Community of Revine Forest” concept. The main interventions include an urban forest, a therapeutic garden, a community farm, an outdoor exercise area, and a multipurpose area. Ecologically sustainable design has been integrated into the planting strategies and water management to create a resilient ecosystem, mitigate flood and improve water retention capabilities of the area for irrigation purposes.

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).

The green infrastructure master plan of Udon Thani aims to prepare the city for the future development challenges by offering a new infrastructure network that can mitigate flood and drought while enhancing community and public space within the municipality. Udon Thani is an important economic city in the northeastern part of Thailand and is growing rapidly. With urbanization and climate change trends, the city is experiencing water supply and flood challenges. The masterplan consists of four main design strategies including canal restoration, green streets, retention parks and wetland areas. All four mains strategies create multi-functional spaces that promote environmental and social benefits together. Aside from slowing water flow which allow infiltration and retaining water, these spaces act as park and community garden which offer passive and active recreational activities. In total, 14 sub-projects were proposed together with cost-benefit analysis. (Ref. 1,2,3,4) Currently, the first project is under construction, which is a canal restoration (Huay Mak Khaeng). The construction is expected to finish in 2024. (Ref. 6,7,8)

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. (Ref. 1,2,3)

In 2016 the Dhaka South City Corporation (DSCC), one of the municipal local government authorities of Dhaka initiated a plan to revitalise 19 of the city’s parks and 12 playgrounds. One of them is Rasulbag Shishu Park, previously a derelict area surrounded by residential tower blocks, tiny shops and street market stalls. Besides reconditioning a derelict area, DSCC considered it of utmost importance to address some environmental and planning aspects. One of them is the fact that Dhaka is located in a region severely exposed to flooding during the rainy seasons. Poor planning of the city, with narrow alleyways, which have no proper drainage, contributes greatly to transforming streets into rivers. As such, in 2018 DSCC started redesigning the area, counting on a participatory approach throughout the community. No trees were taken down throughout the entire process; all other already-existing trees in the park were included in the design. Most of the native shrubs and trees make up the rows of orchards that line the park's perimeter, disguising its crumbling walls and softly merging them into its surroundings. To establish an environmentally friendly and aesthetically beautiful boundary, various plants, including flowers and fruit trees, have been planted around the park's furthest edges. It was expected that the intervention would revitalize a sense of community in an already failed public space. (Ref 1, 2, 6)
