Joint implementation (e.g. tree planting)

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).

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).

The Neela Hauz lake, part of the Neela Hauz biodiversity park, is a natural depression that was once a major source of drinking water for south Delhi, India (Ref 1). Due to nearby road construction and neglect, the lake was filled with solid waste and construction debris for many years. In 2015, based on the request of neighbourhood colonies, the Delhi High Court ordered the restoration of the lake. The Delhi Development Authority (DDA), in collaboration with the Centre for Environmental Management of Degraded Ecosystem (CEMDE) of the University of Delhi, carried out the restoration and revival of the lake using a Constructed Wetland System (CWS). Using the help of natural landscaping composed of oxidation ponds, pebble beds, and furrows having aquatic plants, now the sewage from nearby residential colonies is treated before passing it to the lake (Ref 2). The wetland now converts approximately 1 million litres of sewage per day which has resulted in satisfactory water quality levels (Ref 1). The lake, along with the surrounding biodiversity park, attracts many migratory birds and is also a tourist attraction point in the city. The success story of the lake now has become a model case for the revival of other lakes in the city (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. The center also includes a terrace with a view of the Tuul River, where visitors can relax, and host events and activities throughout the year, including the winter.

In Senegal, urban flooding in the rainy season causes major damage to public and private infrastructure, and poses considerable social, economic and health-related risks to the human population, in particular the poorest. Poor drainage systems mean that rainwater floods the whole neighbourhood, paralysing transport, and economic activities and posing health and safety risks due to stagnation and contamination (e.g. increase in water-borne diseases). To respond to such emergencies, in 2015 several stakeholders (Senegalese government, local authorities in Dakar and the local community) initiated a project that aimed to build resilience to flooding in informal settlements of Dakar. The project consisted of building resilience to floods by focusing on 3 fields: 1) infrastructure (floodwater evacuation, solid waste management, urban gardening and greening); 2) policy (district flood contingency plans and national policy advice); and 3) capacity building (training and awareness building for beneficiaries and key stakeholders, with a special focus on empowering women). The project was concluded in 2017 however its benefits are still felt today by the inhabitants of Greater Dakar. (1,2,3)

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).

"Siargao It Up" is the mangrove conservation programme in Del Carmen, Siargao Islands of the Philippines. The municipality of Del Carmen hosts the largest mangrove forest in the Philippines – consisting of 4,871 hectares as of 2018. This mangrove forest is the habitat of rare and endangered species of flora and fauna both in marine, wetland and terrestrial areas. This ecosystem helps maintain the island's ecological balance by providing rich breeding grounds for aquatic lives. Furthermore, the forest plays a key role in capturing and storing carbon and helps the Philippines to meet its goal of carbon emission reduction. In addition to creating habitats and storing carbon, the forest also protects the community from the inevitable effects of climate change disasters. Recently, in December 2021, it was able to protect the residents from the onslaught of Typhoon Odette. [1, 2, 3]

South Africa is struggling to provide services to the millions of poor people migrating to the major centres and living in informal settlements (shanty towns), built on land that was formerly used for agriculture or pasturage. Vegetation is sparse and the open spaces between the houses are generally of beaten earth. These areas face persistent challenges that undermine health and everyday well-being and increased disaster risk due to their poor design and lack of green infrastructure. Moreover, informal settlements are very vulnerable to flooding events, which affect the quality of life of the people living in them. Such a case is Diepsloot, a settlement in Johannesburg, where a team of researchers implemented a sustainable urban drainage system with the purpose of alleviating poor water infrastructure and addressing issues related to land erosion and environmental degradation. This research has been benefiting from the support of the local population through adaptive co-management and joint implementation of the intervention. (1,2)

In order to promote Urban and Periurban Agriculture and Forestry (UPAF) as a municipal strategy to deal with negative climate change effects, Bobo-Dioulasso local authorities have identified, using a participatory approach, city greenways as experimentation sites for local climate solutions. The intervention consists in transforming vacant land belonging to the city into green corridors (greenways) through market gardens and forestry, retaining the benefits of urban agriculture. Urban agriculture, when planned and managed properly, can contribute to climate change mitigation efforts by lowering the ecological footprint associated with food production. At the same time, urban agriculture can enhance climate change adaptation efforts by increasing vegetation cover and reducing surface water run-off, while at the same time conserving biodiversity.
