Plantar agua- Forestal restoration of Serra do Caldeirao
Rehabilitation of underground aquifers in areas by the planting of native trees and shrubs. The aim is to reverse the degradation of the landscape and ecosystems affected by the fire and to restore their important functions and services, which are fundamental to the environmental balance and well-being of communities. One of the important estimated benefits is the recovery of more and higher quality water for all uses and thousands of users. It is estimated with the mature forest in 2050 that there will be a recovery of 200-250 million liters of water/year, a gain of about 20% in the amount of water that will supply the underground aquifers. The restoration work will involve: - Removing invasive species; - Planting of 50,000 Mediterranean trees and shrubs; - Recovery of riparian galleries; - Monitoring of water, soil and biodiversity.
Rehabilitation of the "Campo Grande" garden southern area
Regeneration of an urban park based on NbS, incorporating biodiversity and renaturing initiatives. Implementation of natural acoustic barriers along the entire perimeter of the garden, which are made by mounds of soil arranged interchangeably between themselves doubling the surface area.
River banks rehabilitation programme
This program for the rehabilitation of beds and riverbanks across the country is expected to cover 5,000 kilometers of water lines over the next few years. The initiative multiplies by five the work carried out after the 2017 fires, which allowed intervention, with natural engineering solutions, in the recovery of almost one thousand kilometers of riparian galleries in 57 municipalities in the Center and North of the Country. Implementing hydraulic passages of dams and pontoons, always using natural-based engineering, besides that many trees have been planted. The intention is not only to renaturalize water courses but to rehabilitate, on its margins, the riparian galleries for which, in an urban context, there is often no space.
Thessaloniki Resilience Strategy
The city develops limited open spaces while at the same time creating spaces for social interaction. It offers solutions such as an augmented green infrastructure (permeable surfaces, rain gardens, and green roofs and walls to manage stormwater and buffer the 'heat island effect) and low-cost solutions such as urban agriculture in inner courtyards, and on private balconies and rooftops. Actions 01: Create a new natural landscape within the built environment: A sidewalk bioswale network to gather stormwater will be set up. This will help with the reduction of heat risks and carbon emissions in the city. It will also afford habitats for urban fauna. The bioswale sidewalk network will contribute towards linking the city's cultural sites, such as the Roman Forum and Eptapirgio Castle. The creation of green routes connecting places of cultural and leisure interest will enhance the spatial quality of the city while augmenting the local sense of identity and the appeal of cultural heritage sites. Cycle lanes may also be included, adding to the network of carbon-free urban transportation routes. Action 02: Install green roofs and green walls on schools and municipal buildings: The bioswale sidewalk network will be augmented by the use of green walls and roofs on several public build
Bird conservation in Lesser Prespa
Preparatory Actions The preparatory actions, form the first and most important phase of the project, as they pave the way for the conservation actions that will follow. The optimal implementation of the conservation interventions requires the prior conduction of specific studies that will set the specifications. Actions: A1. Assessment of wetland vegetation management A2. Guidelines for wetland vegetation management A3. Technical studies for the restoration of function of stream mouths A4. Feasibility study for alternative uses of reed biomass A5. Guidelines for responding to incidences of disease outbreak in pelicans A6. Assessment of habitat vulnerability to climate change to establish “climate change proof” wetland vegetation management. Conservation Actions The conservation actions form the main part of the project and their implementation is based on the directions and specifications that arise from the preparatory actions. They include the management of the wetland vegetation in specific sites which the relevant studies will determine.
Ljubljanica Connects
Restoration of the Ljubljanica River corridor and upgrading of the river’s flow regime: The goal of the project is to enhance the transitivity and connectivity of Natura 2000 sites, by restoring the functionality of the Ljubljanica corridor linking two Natura 2000 sites, i.e. Ljubljansko barge (Ljubljana Marshes) and Sava–Medvode–Kresnice. The project aims will be reached through the removal of fish migration barriers, through the upgrading of the water regime, thus restoring habitats, through upgrading the water infrastructure, water management, and establishment of hydrological monitoring. The earmarked fish species whose habitats are to be ameliorated are Danube salmon (Hucho hucho L.), Danube roach (Rutilus pigus Heckel) and Striped chub (Leuciscus souffia Risso). (University of Ljubljana, 2015). At the outset, the river engineering measures will include the sealing of the weir situated before the railway bridge over the Ljubljanica in Zalog. Thus, during arid conditions, the water level shall not be diminished and the conditions in the oxbows of the Ljubljanica upstream will get better. The fishways at the dam at the Fužine Castle and the sluice gate at the Ambrose Square will be refurbished and repristinated. This will permit the migration of fish, which is now severely
Water LA
Given the city’s environmental challenges, the Water LA program and its collaboratives build pathways to partnerships between agencies, non-government organizations, and the private sector to realise work at all levels. Through a case-study of a parcel-scale water management project in the City of Los Angeles, they explore the social, environmental, and economic impacts of retrofitting residential property into spaces of water capture, conservation, and reuse. These interventions transform parcels into spaces that help heal and improve the urban environment and improve quality of life. To highlight the targeted, small-scale nature of these strategies, they refer to this approach as “urban acupuncture.” Water LA provides a case study of 22 parcel-based retrofits (rain grading/rain gardens, infiltration trenches, permeable paving, parkway retrofits) carried out in LA’s San Fernando Valley. Detailing the program’s successes and hurdles, they aim to provide actionable information for urban stakeholders seeking to implement parcel-scale, nature-based solutions across their cities in a widespread, systematic manner. Over the course of the Water LA programme, the project team was able to amend a number of restrictive building codes, developing a streamlined greywater system permitti
Constructed wetlands system for wastewater treatment in the village of Castelluccio di Norcia
A Contructed wetlands system for wastewater management has been implemented. In the first stage, a French system (with "French " vertical flow reed bed filters - RBF) of purification has been implemented. The second stage consisted of two vertical subsurface flow basins (VF), confluent in two surface flow systems, which will provide the recreational aspects of recreating wetlands with typical aquatic plants of the plateau and will promote the evapotranspiration processes. The effluent is finally reused for groundwater recharge, by an infiltration area connected to a sub-irrigation trench. (IRIDRA, 2021).

Combined sewer overflow of Gorla Maggiore (CSO): The "Water Park"
A treatment plant was set up for the treatment of the first flush coming from the CSO device and from an extended retention basin for the accumulation and the slow release in the river of the second flush. It consists of 4 sand filters, vertical beds, and a retention basin. A small flux is permanently diverted from the river to feed a small pool located on the bottom of the extended retention basin, to permit the development of a highly diversified ecosystem that will offer multiple pathways for the removal/control of several pollutants.
