Neknampur Lake, also known as Ibrahim Bagh Cheruvu, located in Hyderabad, Telangana State of India, has historical importance and was part of a water reservoir network for irrigation and drinking as well as an inalienable part of the rural ecology of the village (1,2). Due to urbanization, the lake underwent drastic changes in ecology, land use and management in the past decade. Scientific investigations conducted by the Telangana State Biodiversity Board on Neknampur Lake highlighted that the water body was full of sludge and extremely eutrophicated, showing elevated algal growth (2). This was mainly because of the unabated entry of sewage and other waste over an extended period into the lake (1,2). In June 2016, The NGO named 'Dhruvansh' decided to adopt Neknampur Lake and thus began a series of interventions that incorporated bioremediation and phytoremediation techniques, regular cleanup drives of plastic removal and recycling campaigns into a restoration plan for the lake (1,2). With the support of the government institutions, 'Dhruvansh' began the revival of the lake across two phases: (1) the revival of the lake periphery and the lake body, followed by (2) the revival of the lake ecosystem (1,2). The ecological restoration of Neknampur Lake has improved the ecological services it provides and restores the glory of this historically significant lake, now known as a biodiversity hotspot (1,2,3,4).

The Upper Kinta River Basin covers an area of about 31,470 hectares above Ipoh City, and it is the main water catchment resource for the residents of the city and its surrounding areas. The Kinta river basin is now threatened by land erosion, land development, improper sewage treatment and irresponsible waste discharges (Ref 1). In 2021, a pilot project was implemented near the city of Ipoh along the SimpangPulai Highway and experimented with river bio-engineering techniques to reduce soil erosion and subsequently prevent sedimentation downstream (Ref 3). The pilot site was established as part of the Mainstreaming Biodiversity Conservation into River Management project, which focused on applying nature-based solutions for mainstreaming biodiversity into riverine landscape planning and watershed management in Malaysia. To provide seedlings for the bio-engineering project and also other related initiatives, a nursery was established in the indigenous Pawong Orang Asli Village. The nursery also provided additional income for communities (Ref 4). The pilot was developed with the expectation to be upscaled and replicated in other parts of the UKB, especially along the SimpangPulai Highway. (Ref. 6)

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 Adopt-a-Park project is an urban re-greening and renewal program. The Metro Manila Development Authority (MMDA), working together with the 17 Metro Manila local government units (LGUs), has launched the initiative to address rapid urbanization and urban decay by creating new green areas and renovating existing but underutilized or derelict neighbourhood spaces [4]. The project is part of the "I ♡ Metro Manila" advocacy program of the MMDA, which was launched to "uplift the spirits of the residents recovering from the impact of the COVID-19 pandemic as well as to strengthen initiatives on urban renewal that aims to transform the metropolis to be a more livable, greener, and resilient region"[1].

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 project “Enhancing climate resilience of Gorakhpur by buffering floods through climate-resilient peri-urban agriculture” is part of the Asian Cities Climate Change Resilience Network (ACCCRN) and financed by The Rockefeller Foundation. It was implemented by the Gorakhpur Environmental Action Group (GEAG) from June 2012 to May 2016 to demonstrate how ecosystem services generated by peri-urban agriculture can positively address the impacts of climate change in Gorakhpur, a city located in eastern Uttar Pradesh, India (Ref 1, 2). To be more specific, it was set out to “demonstrate flood risk mitigation through the preservation and improved management of open spaces by strengthening agriculture-based livelihoods in peri-urban areas” (Ref 1, 2). The main project outcomes were focused on conserving peri-urban agricultural land areas as they serve to climate-proof cities and build resilience, enhance the livelihood and food security of vulnerable groups in peri-urban areas, as well as establish sustainable and climate-resilient models (Ref 1). Activities like baseline surveys, field interventions, climate resilient extension systems, the adaptation of practices and research and advocacy were carried out to achieve the project outcomes (Ref 1). Additionally, the project has successfully improved the soil and water quality and developed special measures for waste management (Ref 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).

Park Podnikolie, with an area of about 100 hectares, is part of the water-green frame of the city and is included in the conservation zone of the historical and cultural value of the city of Mogilev [4,11]. Since olden times on the territory of Podnikol, there were up to 400 manor plots, occupied mainly by vegetable gardens. Now Podnikolie is a large park, which has become a favourite place for residents and guests of the regional centre [1]. More than 1125 tree saplings have been planted on the territory of Podnikolie to preserve the integrity of the historical ground, the historical territory [1,9,10,11]. Thus, the park is also called the "green heart" of Mogilev city. The densely planted area is officially a quiet recreation area where people "merge" with nature [1,2,6,10]. The project's goal is to improve the urban management system, promote the implementation of the principles of green urban planning, and improve citizens' quality of life through effective cooperation between local authorities and the population [2,9,10].

Senegal, like many other West African countries, is in an unprecedented position when it comes to the threats climate change poses. Climate scientists predict that the country will likely experience increased temperatures, decreased annual rainfalls, a rise in sea levels, and an increased frequency of heavy rainfall events. Automatically these events will change drastically the social and economic structures of the country and are reasons for concern for the people of Senegal and their government. For example, the city of Thiès is in an area where environmental degradation is very advanced. The tree cover is in a situation of extreme fragility due to tree ageing or abusive tree cutting. To address many of these concerns, the city of Thies is trying to become sustainable through the development of green spaces that are expected to restore the city's ecological dimension and contribute to the reduction of greenhouse gases and the improvement of the living environment.

Around 90% of Guyana’s population lives in an area that is below sea level, with many inhabiting flood-prone areas along the coast. The coastal plains are also home to about 75% of the country’s economic activities, including almost all of Guyana’s agricultural production. Over the years, degradation and loss of mangrove forests have resulted in increased coastal flooding and saltwater inundation of agricultural land. Mangroves contribute substantially to sea defence in Guyana by damping wave action and reducing wave energy, trapping sediments and stabilizing shoreline substrates while playing an important role in carbon sequestration.
The Guyana Mangrove Restoration Project was executed during 2010-2013 under the National Agricultural Research & Extension Institute. Following completion of the Project phase and given the importance of mangroves to Guyana’s coastal defences, mangrove restoration and management were integrated into NAREI (the National Agricultural Research and Extension Institute), a national institution that promotes climate-smart agriculture and resilient citizens.
