A 7-hectare pilot public project, the Tebet Eco park is located in South Jakarta in a neighbourhood that is densely populated. Previous to the intervention the park was in an acute state of deterioration and prone to floods as well as ecological degradation, as the park is streamed by a river which made it only more susceptible to heavy rains. As such, the municipal authorities of Jakarta planned to revitalize the area by " increasing the hydraulic capacity of existing canal, improving site-wide pedestrian connectivity, and adding new recreation program". This meant that the park was transformed by planting and conserving new and older trees, as well as using vegetation and natural embankments. Furthermore, the implementer planted riparian vegetation to improve water quality by filtering and cleansing surrounding runoff, which also enhanced the site's biodiversity. Besides these elements, a thematic garden, a forest buffer, and a community garden were implemented complementing the entire eco-design that the park aimed for. The park's rehabilitation focused greatly on the human element as it was paramount to provide maximum benefits for park users, the surrounding natural habitats and species, as well as increasing the land value of the area.

In 2018, the Bulat Utemuratov’s Foundation began reconstruction works at the main Botanical Garden in Almaty at the request of the Institute of Botany and Phytointroduction and with the support of the governor of Almaty city [1, 5, 6]. The goal of the project was the restoration of the botanic garden with preservation of its original green character and the modernization of its infrastructure [2, 5]. Taking into account the special status of the Botanical Garden and the high public interest in the reconstruction project, the Foundation ensured full transparency to the public. Taking public recommendations into considerations, the schematic design of the reconstruction was approved in the autumn of 2018 [6]. The project also aimed to do no harm to the existing flora and fauna of botanical gardens, and apply new technology to provide long service life to the garden [1, 4].

To achieve the project's goals, the water supply system was restored, drip and auto irrigation systems were created. Around 174.3 thousand plants were planted, including more than 1300 trees. Additionally, 50 thousand sq.m of roads and paths were repaired, lighting systems and video surveillance systems were installed, and the garden furniture was renovated [1]. The project also resulted in the development of three new entrance pavilions with an electronic ticketing system. A mobile application with a garden map and a description of the green areas has been developed [5]. Special attention was paid to the accessibility of all zones of the Botanical Garden for low-mobility groups. [1, 4, 5, 6].

Confirming the success of the project, within three months after the reconstruction was completed, over 210 thousand persons visited the Almaty Botanic Garden [6].

The Ecological Education Center (EEC) is a nationally recognized institution committed to promoting awareness and sustainability through its environmental education programs in Mongolia. As the only organization in the country dedicated to providing such programs, the EEC operates under the National University of Mongolia (NUM) and was founded in 1957 as the "Central Station of Young Naturalists". With over 60 years of experience in environmental education, the EEC offers its programs not only to NUM students but also to children of varying ages. Since 2011, the center has developed and introduced various cognitive-based environmental training programs, providing visitors with interactive learning opportunities that takes them through different learning stations. The EEC has several facilities to support the learning experience, including a nature experience garden, a greenhouse, and a small zoological museum. The nature experience garden is continuously enriched with new tree species each year, and as a result, it is now home to over 3500 trees and bushes of 30 different species. In addition to its educational programs, the EEC also provides advice on gardening and plant care to further promote environmental sustainability. (Ref. 1, 2, 3)

In 2010, to revamp the Raja Musa Forest Reserve (RMFR), a rehabilitation project was initiated by the Friends of North Selangor Peat Swamp Forest Association (a local NGO) in collaboration with governmental and non-governmental stakeholders. As part of the largest peat swamp forest complex on the West Coast of Peninsular Malaysia, the Raja Musa Forest Reserve (RMFR) is an important home to many threatened species, as well as a valuable ecosystem in the fight against global warming. Despite this, over the years the forest has been subjected to fires and illegal encroachment which severely reduced its area (1). The project was considered unique as it was an innovation aimed to enhance and strengthen the capacity of the local community in peatland water management and forest rehabilitation works (3,5). Activities included among others rehabilitation of the degraded peat forest through the plantation of new seedlings, demonstration of, and provision of a documentary model for community-based peat swamp forest rehabilitation, as well as the creation of an awareness programme with the local community and dissemination of educational materials (2).
The importance of the intervention consists not only in the implementer's approach in regard to nature-based solutions but also in its aim of documenting a "model of low-cost hydrologic restoration of peat swamp forest" which ultimately should be replicated in similar conditions but in various locations (2).

In 2017, the city of Jakarta initiated a peri-urban farming program under its Urban Agriculture Program that aimed to achieve sustainable agricultural production, rural economic sustainability and long-term environmental sustainability (1,4).
South Jakarta is one of the five administrative units that form Jakarta is a prosperous city with more than 2.2 mils. inhabitants. Industrial production as well as urbanization developed quickly in the city, leading to a steep increase in population. Meanwhile, the city experiences a reduction in agricultural land converted into settlements and industrial land, as well as soil deterioration. The city needs agricultural land for production and to establish food security. Furthermore, it needs to improve air pollution as well as oxygen provisioning. As such a solution had to be found (1).
To implement the program a total of 12 communities in the South Kebayoran Lama subdistrict of South Jakarta participated in implementing and operating urban farms. One of these communities has been the Kebayoran Lama Selatan Urban Village managed by Seruni Indah Farmers Group (Kelompok Tani Seruni Indah) which is a very successful example of sustainable organic urban farming supporting more than 3500 residents. The engagement consisted in using vacant and private yard land for horticultural crops (vegetables, fruits and ornamental plants), spices, medicines, herbs etc. through hydroponic and conventional practices that could benefit the community and the general public. 15 gardens have been implemented with funding provided by the Indonesian government (3, 7).

The Kota Damansara Community Forest Reserve is a forest located 10 km west of Kuala Lumpur in the state of Selangor and is the oldest managed forest reserve in Peninsular Malaysia. As the reserve was threatened over the years by plans for clearing and housing development, the community located in the township close to the forest sprang into action to salvage the forest. As early as 2003 an organization called Friends of Kota Damansara was formed to lead a diverse group of concerned individuals, organisations and communities to rally together to vocally defend the forest (2, 3). Efforts to protect and conserve the forest focused on a series of activities such as the development of a biodiversity management plan, awareness-raising activities, educational activities, building capacity activities, and the creation of an ethnobotanical garden to showcase Temuan (local indigenous people) knowledge of plants (1). These efforts were funded with the help of the UN's GEF's Small Grants Programme and led to the reserve being officially gazetted as of 18 February 2010 (Sel GN 398/2010) and being classified as amenity forest, education forest and research forest, making up 3% of land area in the state of Selangor (1, 2). Nowadays, the Kota Damansara Community Forest Reserve Trails is a popular weekend destination for mountain bikers, trail runners and casual hikers (3). Furthermore, the KDCFP has become much more accessible and utilizable by visitors from various categories of societies, besides researchers discovering and documenting a number of species of flora and fauna unique or endemic to the park (1).

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).

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. [1,2].

18 km southwest of Karachi City (Sandspit area), the World Wildlife Fund Wetland Center (an NGO subsidiary of the WWF) started a project in 2011 called Nurturing Young Sapling with a grant from the Mangrove for the Future organization. The project aimed to increase the mangrove forest cover near Karachi as to restore the ecosystem and improve the habitat for local and migratory birds, crabs and other fauna. In this way, the project sought to improve biodiversity and therefore the availability of livelihood resources to the local community, as well as to enable ecotourism. It also focused to enhance the awareness of school children on the importance of a mangrove ecosystem and advocating for its sustainable use (1).
The project benefited local fishing communities, school children and their families as well as local and international visitors to the Sandspit area. The project resulted in the mangrove plantation at 4.5 hectares area, the establishment of a mangrove (Avicennia Marina) nursery, the plantation of 5000 mangrove saplings, awareness raising of 200 school children, two-day awareness conference, the celebration of significant environmental days at the Wetland Centre to promote conservation awareness among school children (1, 2, 3).
After the successful completion of the project in 2012, WWF Pakistan has been actively involved in the management and plantation of mangroves in the Sandspit area. Multiple campaigns and awareness-raising programs for coastal protection are conducted by WWF in their Sandspit office with multiple partnerships to plant and educate students and communities about the importance of mangrove trees.

Since 2012, the Municipality of Ipoh continued the revitalization and rehabilitation of the D.R. Seenivasagam Recreational Park (TDRS) under the Malaysian National Urbanisation Policy, which suggests that for every 1,000 inhabitants, there should be public green open spaces of 2 ha. Through this intervention, the Ipoh municipality tried to address several sustainability challenges, which are usually a result of the lack of green open spaces. Some of the challenges addressed were the urban heat island effect, soil erosion resulting from improper drainage, and noise pollution. Ultimately, the municipality aimed to provide a convenient setting for a variety of leisure and recreational activities in addition to enhancing the civic values of the community. The intervention consisted of several tree-planting actions organized by the Ipoh Council in collaboration with the Perak Government (a Malaysian state that has its capital in Ipoh).
D.R. Seenivasagam Recreational Park was built in the 1950s and is one of the largest urban parks in Ipoh. It has become a favourite among locals as well as an example of good practice for integrating green open spaces in addressing sustainability challenges over the years. Located in the vicinity of the Kinta River, during the early days of its opening, it was a mini botanical garden which eventually transitioned to a full-scale park, one of not too many in Ipoh. The park also includes a lake with wooden bridges that contributes to the diversity and habitat of the place. The DR Park, as it is known to the locals, has entertained many families for more than 25 years, starting as a mini-theme park during its formative years, much to the delight of many children. To date, the park has remained a popular spot with abundant greenery and attractions, an oasis within Ipoh’s city life. (1,2,3,4)
