Set up for multiple NBS interventions, including this one

Rising temperatures, longer dry spells, more intense heavy rainfall and sea-level rise, make Tanzania the 26th most vulnerable country to climate risks. Dodoma, the country's capital, is a city with a rapid rate of urbanisation and uneven population growth. The near-central business district, peri-urban and urban parts of the city, have grown very fast as a result of intensified urban planning and surveying of land. A way of addressing these stringent issues was developed by ICLEI, an international NGO, which focused on the relationship between nature and urban planning and initiated an intervention in the form of a community farm in Dodoma.
This project aims to develop, 15 km from Dodoma's city centre, a community farm that will focus on producing enough food for the inhabitants of the city and its surroundings. The farm is the first in a project that will try to establish foodways. Foodways include customs of food production, preservation, preparation, presentation, gathering, marketing (both buying and selling), uses of food products other than for eating and food folklore.”The project dates back to the beginning of 2020, and it is still ongoing.

The main rivers that cross Lilongwe are the Lilongwe, Lingadzi, Nankhaka and Chankhandwe Rivers, of which the Lilongwe River is the biggest and longest river and the primary source of water for Lilongwe city's residents. At 200 km long, besides its primary function, the river also supports several informal settlements and provides ecological, recreational, cultural and economic benefits. Despite these important functions that the river offers, it is still facing threats such as pollution, urban agriculture, sand mining, climate change effects, and a loss in the biodiversity of fauna and flora that this watercourse hosts. As it sustains a population of approx. 1 mil. inhabitants, the local authorities were interested in finding solutions to address the above threats. As early as 2016, ICLEI ( Local Governments for Sustainability), an international NGO that promotes sustainable development, worked alongside Lilongwe City Council and other stakeholders to protect the river as well as the people depending on it and implemented several actions, with the help of the local community. Eventually, this collaboration led to the issuing of a strategic plan for a sustainable and functional ecological corridor system in the heart of Lilongwe City. The Ecological Corridor aims to transform Lilongwe into a green, clean, prosperous, and resilient city, by ensuring the protection of its urban natural assets, and advancing complementary nature-based solutions. 1,2,3)

The project has seen the "installation of rock structures to reduce the energy of the water that is drained by conventional rainwater galleries and the strategic planting of certain plant species that, through phytoremediation, can mitigate the diffuse pollution that affects the body of the river" (Ref. 1). In combination, "these solutions aim to prevent erosion and landslides on the banks, stop the siltation of the river, improve water quality and strengthen the linear park as a leisure space increasingly demanded by the population in its surroundings" (Ref. 1). A demonstration project which occurred under ICLEI's INTERACT-Bio project, the implementation of NBS has also been accompanied by other measures which saw Lake Cabrinha be de-silted, a walking path, benches, and playground be built and LED lighting be installed" (Ref. 1).

Beirut RiverLESS, a project initiated by OtherDada, aims to address the deterioration of the Beirut River and its negative impact on the surrounding communities and environment by developing a holistic response plan for the Beirut River Watershed. The river runs east to west, then curves north, separating the city of Beirut from its eastern suburbs, primarily Bourj Hammoud and Sin el Fil. The goal is to bring the Beirut River back to life by following a Landscape Ecology approach and by enabling local governance, leading to innovative ecological interventions. Throughout time, the river has been used as a water resource for drinking and irrigation. It also once had an important role as a space for recreational activities. In 1968, the river was transformed from a natural, healthy and performing ecosystem to a canalized infrastructure, becoming an open sewer of domestic and industrial wastewater, highly polluted and posing numerous health risks to its neighbours. The river also lost its recreational and social function as people no longer had access to it. (1)

Al Shaheed Park is the largest park in the country. The park was designed to include besides its green spaces, several buildings (museums, parking) populated with green roofs and an artificial lake. The size of the park with all the mentioned grey and green elements stands at 20 ha. The park is viewed as an encompassing part of a green belt that surrounds the city of Kuwait. From an environmental point of view, the park was built to protect the city from sandstorms and to reduce air pollution. From a cultural point of view, the park and the museums are providing the public with high-quality programs, events and spaces, and part of their mission is to spread awareness and educate the public on the importance of the country’s land, history and environment, in addition to the encouragement of international and regional exchange of arts. In addition, the park is meant to commemorate the victims of the first Gulf War. (1,2,3)

The Armenia Tree Project is a national initiative founded in 1994. The project engages in involving different community members in an urban planting program, environmental education and outreach. ATP has targeted the most vulnerable communities with the most need for greenery. The focus and attention that is given to these areas help trees to grow and flourish but also creates a stronger bond between the inhabitants and the land they live on. Major greening sites are typically public parks, schools, kindergartens, cultural centers, military bases, churches, historical monuments and other significant landmarks. ATP also focused on Yerevan, the capital of Armenia which has become the "theatre" of many planting campaigns. From a climate change perspective, the project addresses issues of clean air and temperature regulation, as Armenia confronts a frequency of extreme weather events, worsening desertification and land degradation. From a biodiversity perspective, the project aims to conserve the country's rich biodiversity and to restore its ecosystems. (1,2,3)

The Porsuk Stream divides the city of Eskişehir into two with a green corridor running along the shores of the stream. The Porsuk Stream served provisioning services and acted as a recreational area in the first half of the 20th century, however with increased industrial activities discharging untreated wastewater into the river, rapid urbanisation in the city and other settlements, and increased fertilisers and pesticides in the groundwater originated from agricultural practices (upstream of the Porsuk River), it became highly polluted and its ecosystem degraded severely (1,2,4,5). The Organization for Security and Cooperation in Europe (OSCE) identified the stream as one of the highly dangerous rivers in terms of pollution and health, where no living beings except viruses live (1).
Within the framework of the 'Eskişehir Urban Development Project' the 'Natural Disaster Loss Reduction Project (Porsuk Project)' has been initiated focusing on the ecological restoration of the stream, improving water quality, increasing the resilience of the city against natural disasters (as earthquakes and floods) while also reestablishing the stream's environmental and social role in the city (1). A network of natural infrastructure was created along the Porsuk by expanding public green spaces and link the entire corridor with a sustainable public transport network. (4,5)

In 2019 at the Gullele Botanical Garden in Addis Ababa, the Ethiopian government launched a historic tree planting campaign. Over 350 million trees were planted in an ambitious move to counter the effects of deforestation and climate change. The Gullele Botanical Garden was selected as one of the 1000 sites all over the country involved in the Green Legacy Initiative, a national campaign against the effects of climate change. The United Nations estimates that Ethiopia’s forest coverage has declined drastically to a low of just 4 per cent in the 2000s from 35 per cent a century earlier. (1,2) The Botanical Garden was not selected aleatory as it is Ethiopia's only botanical garden and it is a nursery for various indigenous plant species. Its mission is to conserve and promote the Ethiopian diverse plants and tree population and it is a conservation initiative located at the northwestern tip of the Addis Ababa City Administration. The site covers an area of 1000 ha which is representative of the central plateau of Ethiopia. (3)

The project is part of a bigger initiative aimed at restoring the coastal forest near the city of Mahajanga in western Madagascar. Alongside 2 international NGOs, the community located in the bay next to the city of Mahajanga implemented the intervention with the ultimate goal being to transition the land into a protected area as part of the greater "Mahajanga Green Belt Project". The regrowing forest will form the northwestern end of the greater Mahajanga Green Belt, with the southeast meets the Ankarafantsika National Park. The project also has a gendered aspect as it aimed to employ mostly the women in the suburbs of the city. (1,3)

A greening project in Laval aimed to replace impermeable surfaces such as asphalt with vegetation. This process would allow water to infiltrate the soil on a surface area of 3000 square meters and plant 7200 plants on land located near or inside urban heat island zones of the city (Ref. 1,2,3,7). The project takes an integrated approach to mitigate the impact of urban heat islands, which make up 12-13% of the territory in Laval (Ref. 1,7). Particular focus of this project is placed on planting on sites of vulnerable communities (Ref. 1,3).
