Environmental regulation

Ensuring that Ivorians, from an early age, pay attention to the environment, it is one of the Ivorian government’s many environmental objectives. As such, in 2019, the Ministry of Water and Forests initiated a project in the Mamie Fêtai Highschool of the city of Bingerville. The initiative is part of a bigger project that aims at raising awareness and tries to engage the Ivorian school in the recovery of the forest cover of the country. Ivory Coast is a delicate case in West Africa, from a forestry point of view. Since 1960 the country lost more than 80 percent of its forests, mainly to cocoa production and agricultural practices (1,3)

The Million Trees project was a programme launched by Auckland Mayor Phil Goff in 2017 to plant a million predominantly native trees and shrubs over a period of three years (Ref. 1,2,3,4). It aimed to make Auckland a greener, more beautiful place while creating carbon sinks, protecting the city’s waterways and improving the city’s living environment (Ref. 2,4). The programme engaged a variety of actors in the planting activities, including local boards, iwi, schools, service and social sector groups, private entities, the council group, the New Zealand Transport Association (Ref. 1). Particularly notable partnerships included those with the Department of Corrections and the Trees that Count Trust (Ref. 2,4,6).
The initial goal was met in 2019, and the project has been renewed for 2019-2022 (Ref. 1,7).

The wetlands to the east of Kolkata are well known over the world for their multiple uses. The locals are using the naturally occurring wetlands for wastewater fisheries and vegetable farming on garbage substrate & effluent irrigated paddy cultivation. In the process, the wetlands treat the wastewater and have saved the city of Calcutta from constructing and maintaining a wastewater treatment plant. Currently, encroachment has deteriorated the wetland ecosystem significantly. This intervention is about the management of the degraded wetland to recover it the best way possible. The goal of management planning is to „maintain East Kolkata Wetlands in a healthy condition to enable the delivery of its full range of ecosystem services and sustain biological diversity values’.

The Recreio green corridor project, launched in 2012 by the Municipal Secretariat for the Environment and several city departments, aims to protect and enhance the rich biodiversity and ecosystems of the area, to help with the resilience and adaptation of the west side of the city, an area affected by coastal flooding and erosion. The project mostly focused on preserving, connecting, and expanding the existing local urban nature elements and protecting their ecology. Lastly, the project also aimed to educate the residents about native vegetation and help build social interaction and cohesion between the local communities [Ref 1]. The project was designed to preserve and connect 320.76 ha of protected areas and add 60.73 ha of open public spaces and squares. And in total, the corridor has a linear extension of close to 8 kilometers, passing through very diverse urban areas (Ref. 7), including natural parks, a lagoon system, water canals, and social housing areas.

"The Urban forest strategy (UFS) is a central part of an innovative overarching policy framework of the City of Melbourne underpinning the city's aim to create healthy ecosystems for people and nature" in the period between 2012-2040 (1 p9). The UFS outlines a scientifically-vetted long-term process to re-nature the city with a diverse selection of urban trees and open space for and with the citizens, combining elements of an eco-managerial governance arrangement with an open and reflexive co-governance approach. (1 p11). The Strategy concentrates on 6 areas to achieve its goals: canopy cover, forest diversity, vegetation health, water quality and soil moisture, urban ecology and environmental stewardship among citizens.

The Porous Alley consists of a strip of porous asphalt in a public alley aimed at filtering stormwater and managing runoff in the affluent South End neighbourhood of Boston. Most of the neighbourhood around the NBS location is filled with land that once was tidal marshes, supported by wood pilings, and threatened by falling groundwater levels. The Porous Alley was designed and implemented as a demonstration project to test the feasibility of using porous asphalt to increase groundwater recharge and reduce flooding and water pollution. The increasing groundwater level has high importance in the area the NBS is located in as building foundations are at risk from low water levels. (1,2)

The Gorla Maggiore water park, inaugurated in March 2013, is situated within the municipality of Gorla Maggiore, in the Italian region Lombardy, located about 30 kilometers northwest of Milan. The water park is a constructed wetlands (CW) built on the banks of the Olona river that includes (a) a pollutant removal area composed of a grid, a sedimentation tank and four vertical sub-surface flow constructed wetlands; (b) a multipurpose area with a surface flow constructed wetland or pond with multiple roles; and (c) a recreational park with restored riparian trees, green open space, walking and cycling paths.

The Gran Recorrido de Bilbao (GR), known as the Green Ring or Great Route of Bilbao, is a part of Bilbao’s Green Belt, a municipal initiative that encompasses forest and urban parks surrounding the city. The Green Route aims to skirt the City passing through the forest parks of Artxanda, the mountain of Avril, Arnotegi, Pagasarri, and Arraiz. It completes a route of 99.3 kilometers in a closed belt of trails, paths, roads and streets signposted with references to routes, interesting places, and general information. The Green Route is reachable from the center of Bilbao through eleven additional routes that all lead to a central point. [3][4]

The Lama Balice Nature Park is located near a long 'lama', which is a deep karst gorge, located north of the city of Bari. Established in an abandoned site, the nature park protects the area of the riverbed in the periphery of the city, acting as a natural channel for regulating water flow. It also serves as a recreational and cultural hub, while conserving agricultural functions and maintaining biodiversity. An administrative body consisting of the participating local mayors has been set up to manage the protected area. [1][2]

The aim of the FitzSimons Wood Biodiversity Education Programme is to highlight the value of, and to promote the use and care of biodiversity and green space in the local area through learning exercises and activities taking place in FitzSimons Wood park. To support such educational activities in the park, enhancement of the habitat was carried out by developing footpaths, planting native trees and management of invasive species. Also, a detailed handbook for school teachers was produced with guidance on how to lead school activities where students investigate local wildlife. (Ref. 1; Ref. 2)
