Droughts are one of the most serious threats to water availability, food security, and local livelihoods in the semi-arid areas of Tanzania. Drought condition is coupled with a rainfall deficit and poor rainfall distribution. In Tanzania, drought conditions are observed more frequently in the country's northern and central portions (Arusha, Manyara, Shinyanga, Simiyu, and Dodoma). This consideration was paramount when in 2019, the Municipality of Dodoma, alongside ICLEI - Local Governments for Sustainability, erected a new garden positioned in a square in the centre of the city. Nyerere Square in Dodoma used to be an open, concrete space with the statue of Julius Kambarage Nyerere the only attraction apart from the informal traders scattered along the main walkway. Nyerere is the former prime minister and president of Tanganyika, as Tanzania was known before, and subsequently president of Tanzania. It would prove challenging to sustain such an initiative in this drought-prone city. To ensure the park outlived the project, the team installed a greywater system to irrigate the new garden and ensure there was always sufficient water to help the plants flourish. (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)

The project focuses on encouraging residents of Rio de Janerio's Arará favela to install green roofs on their homes, primarily to reduce the urban heat island effect but also to harness the broader social, environmental, and economic benefits which green roofs can provide, "...from providing thermal protection and improving air quality to mitigating stormwater runoff pollution and saving costs for both residents and cities" (Refs. 2 & 3). The individual behind the project, Luis Cassiano Silva, further hopes that introduction of green roofs into the favela which help to improve residents’ quality of life and "describes the emotional benefits of incorporating green space into the favela landscape" (Ref. 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.

The Rioni River basin is the second largest in Georgia, originating in the Greater Caucasus range and flowing into the Black Sea, traversing the town of Samtredia. Samtredia has been affected directly on many occasions by floods that have become a current occurrence in the Rioni River basin as of late. The underlying causes of vulnerability to climate change in the Rioni basin can be categorised into 1) physical factors –direct manifestations of climate change, 2) factors caused by anthropogenic intervention – those related to the harmful ways in which humans have and continue to interact with the environment which has exacerbated vulnerability and 3) Institutional factors – related to the legislative/regulatory barriers placed by government and other institutions, as well as limited capacity (human and resources) to manage climate change vulnerability. Flooding has been harmful not only to the local population but also to the biodiversity of the area, which suffered losses and an ecological imbalance and a disruption in the habitat patterns of local fauna. Many of these issues became the focal point of an activity developed by the Adaptation Fund alongside the Georgian government as early as 2012. The intervention stretched for 4 years and involved several localities in the Rioni River Basin, including Samtredia municipality, consisting of creating bank terracing, vegetative buffers, and tree revetments in order to address floods related to the Rioni River basin and the localities it traverses.

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 Ras Mekonnen Urban Park is part of a larger intervention developed by ICLEI (an international NGO focused on the promotion of sustainable development) with the Addis Ababa municipality alongside the Shega river that crosses a nearby neighbourhood. The location of the park was initially used by locals as a dumping site affecting not only the quality of life of the inhabitants but also contributing to the environmental degradation of the area. As more and more people discarded their waste here, the small river running through the site, a tributary of the Shega River, became increasingly overgrown and inaccessible, resulting in a derelict, run-down space in an otherwise vibrant urban area. As such, action was needed, which eventually resulted in the rehabilitation of the river and the creation of the park, which now can be enjoyed by all the inhabitants of the Ras Makonnen neighbourhood.

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)

Typically considered dividers of the urban space, ravines ('barrancos') which run through Guatemala City are being targeted for an overhaul of their reputation and are instead being reframed as a way to bring people and their environment together (Ref. 3). Now metamorphosed into a grassroots movement, 'Barranqueando' "wants to continue integrating the ravines with the urban environment to generate ecological, social and economic benefits for their city", where the unexplored potential of the ravines can be realised as areas to "serve as natural reserves, as nodes and paths for sustainable mobility throughout the city, as rainwater collectors, as crucial carbon sinks, as well as for purifying and cooling the air" (Ref. 3).

One of the first projects of the movement was the development of Jungla Urbana, an ecological park that brought together a ravine and the adjacent urban space, "giv[ing] residents the opportunity to wander through largely untouched nature – and experience the natural ecology of the site their city is built on", and providing an area to "...explore how the city’s unique ecosystem can be used to benefit its citizens – ecologically, socially and economically" (Ref. 3).

Monavale Vlei is an important wetland area within the city of Harare, characterised by miombo woodlands that play an important role in the fragile ecosystem of the Manyame catchment basin, the main supplier of water for the city of Harare and its suburbs. Throughout the years, Monavale has been subjected to a number of threats such as construction developments, dumping of waste, fires, illegal farming, invasive plants, informal agricultural practices and loss of biodiversity. To address some of these challenges the local community organized itself into a group - Conservation Society of Monavale (Cosmo) Trust, to protect the area and, with the help of the municipality of Harare and some international bodies, implemented a series of actions designed to protect the wetland and reduce the loss of biodiversity, among many others. In 2009 the NGO was awarded a United Nations Development Programme Global Environment Facility Small Grant. The intervention had 3 objectives: to restore parts of the wetlands, to advocate with the local and international authorities for the legislative protection of the wetlands, and to engage the scientific community in research regarding the wetlands. This enabled Cosmo to restore Monavale vlei to an almost pristine wetland state, and other UN funding has made possible several training and awareness projects for a wide range of audiences. (1,2,3)
