Dissemination of information and education

One of Valdivia's (in South Chile) southern peripheral neighbourhoods reaches the river of Angachilla which in time led to the creation of an urban wetland, a beautiful and large urban nature reserve of the city of Valdivia. The city of Valdivia is inserted in an extensive network of rivers and coastal wetlands, which penetrate the city through estuaries, hualves and meadows. The Angachilla estuary wetland is one of the most important, connecting the southern sector of the city with the Valdivia River estuary.
These urban wetlands provide important ecosystem functions that directly benefit citizens. Since 2007, the residents of Villa Claro de Luna (neighbourhood) together with various social organisations have worked on the recovery of the Angachilla Wetland, a natural space of great ecological and social value located in the city of Valdivia. Actions included carrying out cleaning, restoration and environmental education activities to recover a place that, abandoned and without any protection from the authorities, was converted into a clandestine garbage dump.

From 1998-2002 Argentina went through an economic depression, which began after the Russian and Brazilian financial crises, caused widespread unemployment, riots, the fall of the government, and a default on the country's foreign debt. Rosario, the third-most populous city in the country, was not a stranger to the crisis' effects as many of its inhabitants were now living under the poverty line. Coupled with this, climate change was heating up the city and making rainfall more erratic, leading to both flooding in Rosario and fires in the nearby river delta. To tackle urban inequality and climate change the Municipality of Rosario developed a program called "Urban Agriculture Program" which aims to give low-income residents access to underutilized and abandoned public and private land to cultivate food. Over the years, the municipality evolved the program into a cornerstone of its inclusive climate action planning. (1)

Climate change has become the day-to-day struggle for this nation - an island nation that faces serious sea-level rise implications should the problem remain uncurbed. The impacts seen are related to rising temperature, sea-level rise (coastal erosion), and changes in rainfall (flooding). To reduce the vulnerability of the population of two regions next to its capital (Victoria), the Ministry of Environment and Energy of Seychelles initiated in 2012 a project aiming at improving the quality of life for the people of Seychelles and restore coastal zones as well as the ecological habitat related to them through nature-based solutions. The project will reduce these vulnerabilities by spearheading ecosystem-based adaptation as climate change risk management—restoring ecosystem functionality, and enhancing ecosystem resilience and sustainable watershed and coastal processes, in order to secure critical water provisioning and flood attenuation.

Mauritius is a biodiversity hotspot, which has been declared by IUCN as a “Centre of Plant Diversity”. 39% of plants, 80% of non-marine birds, 80% of reptiles, and 40% of bat species on the islands are reported as endemic. (4) Nevertheless, human activity keeps threatening this endemicity in Port Louis, a port city and the capital of Mauritius. The city is surrounded by a semicircle of mountains on one side and the Indian Ocean on the other. In 2006 a local NGO started implementing an initiative that focused on restoring native vegetation to the hill that harbours the capital and it's also the place of an important historical heritage, the Fort Adelaide.

A multi-purpose green belt (12 km in length of Batticaloa Municipal Corporation coast) was established to protect the lagoon and coastal areas, restore mangrove ecosystems and improve coastal biodiversity. The project comes under activity 1.3 of the overarching project Climate Resilient Action Plans for Coastal Urban Areas in Sri Lanka (CCSL). The project focuses on the most urgent and immediate needs of the Sri Lankan coastal cities in adapting to climate change, and mitigating risks and the severity of impacts through Disaster Risk Management (DRM). The green belt plantation was done with Casuarinas plantation in 400 ha (out of which 75% by Mandru and 25% by the Forest Department), mangrove forest redesigning and protection of the existing vegetation.

In 2014, a rooftop farming project was initiated in the informal settlements of the Greater Cairo Region to address challenges brought by climate change and to empower the local community. The project was initiated by the German Corporation for International Cooperation and a local NGO with the objective to "reduce ambient temperatures (microclimate) in a densely populated area through green spaces on rooftops, and reduce the impacts of the urban heat island effect and increasing heat." (1) The initiative also addressed four of the Aichi Biodiversity Targets by tackling biodiversity loss, encouraging sustainable agriculture practices, fostering ecosystem services and developing local knowledge (1,11)
Besides environmental benefits, the project and its scaled-up project in 2017 brought several socio-economic benefits by reducing vulnerability to food price changes and by developing the local community. Rooftop Farming Hubs were also established to foster the training and knowledge sharing of rooftop farmers in Cairo (1).

This intervention was initiated in 2014 in Agege, a slum and a city in itself belonging to Lagos. Agege is one of the 7th most populated low-income communities in Lagos with a total population of around 1,033,064 people. Climate change in Nigeria led to seasonal droughts and floods, causing pressures in terms of food security as well as high temperature and humidity levels which affect directly the economically disadvantaged population in the slums of Lagos. In 2014 a research team at the University of Cardiff alongside community leaders of a Yoruba community in Agege implemented a study on vertical gardens in residential areas with the purpose of alleviating local temperatures and enhancing biodiversity. The implementation started with a study and was continued with the introduction of practical gardens maintained by the local community of 3 residential buildings (one in Suru Street, another in Lagos Street in Agege, and a third in Abeokuta Street).

In anticipation of the organisation of the 2016 United Nations Climate Change Conference in Marrakech, the Sidi Mohammed Benabdellah University (USMBA) of Fez has launched an operation to plant 1,000 trees of different species. This intervention was part of a series of scientific, cultural, artistic, sporting and environmental actions undertaken by the University for the Climate, with the cooperation of other partners. Students and faculty as well as NGO representatives were present and implemented the action which ultimately led to the creation of green areas within the campus and around the faculties and universities. Founded in 1975, Sidi Mohamed Ben Abdellah University is named for a 18th century Sultan of Morocco, the nation in which the university is based. The main campus is located in the northern city of Fez, a World Heritage Site and historically the last stop on the famous gold trading route from Timbuktu. (1)

In 2019, the public initiative "Let's return the rivers to the city" campaign united public forces around the Podborenka river, which flows through the territory of Izhevsk along its entire length [1, 4, 5]. In an urbanised environment, the river was abandoned due to water pollution, poor treatment of stormwater, road and industrial runoff, soil erosion, and due to presence of landfills in the valleys [1, 4, 7]. Therefore, the project's primary goal is to increase the efficiency of urban resources and the creation of new scenarios for resource use on the example of the space of the riverbed of a small river [3]. The project implementation contributes to improving the ecological situation of the Podborenka River, its embankment zone and biodiversity [1, 9]. Also, the project implementers paid particular attention to the education of young people, the development of volunteer movements, and raising the level of the ecological culture of the population [1, 2, 6, 7].

In November 2019 the municipality of Hammam Sousse alongside one of the local schools initiated a climate intervention by planting trees next to the banks of the river Oued El Hammam. The municipality of Hammam Sousse is located in the central-eastern part of Tunisia (Sahel region), and as a coastal city, it enjoys a warm Mediterranean climate with a dry summer. The Mediterranean region is ranked among the regions which are the most vulnerable to the effects of climate change and the intervention focused on implementing solutions to mitigate these effects.
