Griffeen Valley Park Wetlands
The Dublin Urban Rivers LIFE (DURL) project incorporates two interconnected wetlands in Griffeen Park as part of its broader initiative to improve water quality, natural water management and aquatic biodiversity in urban areas. These wetlands were specifically designed as a natural sewage system to treat wastewater from the surrounding areas, addressing a significant environmental issue known as "domestic misconnection." Domestic misconnection occurs when household appliances, such as washing machines, dishwashers, and kitchen sinks, are incorrectly linked to surface water drains rather than the sewage system. This leads to untreated wastewater being directly discharged into local waterways, contributing to contamination.
In the River Griffeen catchment, which includes approximately 12,000 dwellings and associated infrastructure, domestic misconnections are a considerable threat to water quality. The DURL project focuses on identifying and rectifying these misconnected appliances to ensure that wastewater is properly treated before entering the river. This process will not only improve water quality but will also provide flood alleviation and support healthier aquatic ecosystems in the area.
The project is aligned with broader environmental policies, including the River Basin Management Plan 2022-2027, the Water Framework Directive, the Climate Change Action Plan, the Floods Directive, and the draft Biodiversity Plan. One of the key strategies is to use a Geographic Information System (GIS) to streamline inspections for domestic misconnections, making the process faster and more cost-effective.
The constructed wetlands in Griffeen Park, with a standing water depth of approximately 30 cm, are planted with a variety of native Irish species. These wetlands offer a natural, sustainable solution to wastewater treatment, with the potential for similar applications across Europe. (Ref. 2, 4)

The Boston Project: Sustainable Neighborhood
The “Sustainable Neighbourhood” project is a pilot initiative led by the Public Environmental Establishment (EPA Cartagena), aiming to achieve environmental management and adaptation to climate change for environmental sustainability in the Boston neighbourhood. The primary objective of the project is to transform these areas into an eco-neighbourhood through activities that promote an ecological culture and raise awareness in the community, thereby enhancing the quality of life in the area, particularly since the neighbourhood is situated adjacent to Ciénaga de la Virgen. This coastal wetland serves as the primary recipient of the city’s wastewater and solid waste. The activities included the restoration of environmentally degraded areas such as mangroves, solid waste collection, environmental education activities, recreational activities, and plastic collection. The project employed a participatory approach, with planning conducted in collaboration with community leaders, public entities, private companies, and other stakeholders (ref 1). Additionally, the EPA conducted awareness sessions on the responsible handling of solid waste, proper water use, and energy service (ref 2). the project seeks environmental management and adaptation to climate change for environmental sustainability, Community leaders participate in these activities with the cooperation and coordination of partners, including Afinia, Guardia Ambiental, Aguas de Cartagena, Comfenalco, IDER, Pacaribe, and others (ref 3).
NatureRx Rain Garden Pilot
The NatureRx Rain Garden Pilot is a community-driven initiative aimed at addressing urban runoff and its associated challenges, implemented by Bí URBAN, a community hub and social enterprise in Dublin focused on urban regeneration. The pilot project developed in Stoneybatter, Dublin involves diverting rainwater from residential rooftops into specially designed rain gardens (1). The area is used as the first trial area by installing around 100 rain gardens (3, 11). Built to fit neatly into available spaces, these self-sustaining planters will filter rainwater through the garden, with overflow pipes in place to prevent flooding during heavy downpours (1).
It is expected that these gardens will transform sterile urban spaces into green areas, enhancing biodiversity, providing habitats for pollinators, and acting as carbon sinks (1,3).

The Lommas Programme
Lomas are endemic seasonal ecosystems found in Peru and Chile. They provide a variety of benefits such as soil stabilisation, air purification, recreational spaces, water retention, and are habitats for endemic and threatened species (Ref 7). They are of great ecosystem value to the city of Lima, as green areas have been reduced in the urban area, occupying up to 24% of urban green ecosystems. These ecosystems are threatened by unplanned urban growth, traffic, pollution and lack of government regulation. Given this context, Eab Lomas is a project that focuses on the conservation, management and rehabilitation of the ecosystems found in the Lomas of Lima (Ref 1, 2, 3, 4, 5). It focused on 4 lines of action: conservation of Lomas' ecosystems; implementation of territorial planning; economic diversification focused on the conservation and recovery of vegetation through low-impact recreational activities; and management of water resources (Ref 1, 2, 3, 4).
IKEA's biodiverse extensive rooftop garden
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].
Green Campus Initiatives at Nazarbayev University
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].

Urban Farming Practices in South Jakarta
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).

Building Coastal City Resilience in Pekalongan
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.

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).

Siargao It Up: Mangrove Conservation
"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]
SuDS in Diepsloot
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)
