Integrated valuation of a nature-based solution for water pollution control. Highlighting hidden benefits

This study assesses the benefits of a multi-purpose nature-based solution for water pollution control in a peri-urban area located in Gorla Maggiore (northern Italy), using an ecosystem service approach and applying an integrated valuation based on MCA for local water management. This solution is compared with the alternative “doing nothing” and with the construction of conventional grey infrastructure. This case study gives an example of integrating different value systems and stakeholders' viewpoints, thus providing hands-on guidance for integrated valuation in ecosystem service...

The D4RUNOFF project’s goal is to create a novel framework for preventing and managing diffuse pollution from urban water runoff. This will be achieved by designing hybrid nature-based solutions (NBS) and a data-driven AI-platform to support policy and decision making.

The case studies have been identified for the implementation and validation of this approach in varying environments. The replicability of these results will then be assessed at five replication sites. The Las Llamas Park in Santander has been chosen as one of three case study sites as part of the D4RUNOFF project.

Flooding problems during heavy precipitation in the Trobekken Creek may affect a development project to establish 220 family housing units.

Through the H2020 project PHUSICOS the Trobekken Creek has been opened and re-meandered. A buffer zone is established around the re-opened creek and is also combined with a sedimentation dam (check dam).

Ecohydrological engineering is used here to enhance the self-purification capacity of a small stream polluted by urban rainfall discharges. The demonstration site, realized in collaboration with the stakeholders, shows the positive effect on the chemical quality of the stream

The urban dominant model in Spain, which is characterized by the diversification of activities and population increase, has aggravated the urban risks and environmental problems that already existed, such as the high consumption of soil, energy, water, and air pollution. It is also important to highlight the significant difficulties caused by the increase in distances, and the permanent requirement of the use of the car. The strategic line of Valladolid is situated within the frame of the urban city model. Its objectives are to develop an innovative and entrepreneurial culture, and to...

Liverpool, as with many major urban areas in the UK and globally, is facing significant challenges in managing its urban form to pursue economic growth agendas, whilst also providing an attractive city for its residents and visitors. Unfortunately, the social, ecological, and economic dimensions of these political mandates are frequently at odds, creating conflicting visions for how urban areas should be being developed and managed. With further densification of urban form, the re-development or conversion of green space into urban land, and a continuing growth spatially of urban...

The main problem to solve with the implemented NBS measures is the runoff of soil and pollutants from the farmland to irrigation canals and from there to the nearby Lake Massaciuccoli on the Tuscan coast.

Through the H2020 project PHUSICOS two canals (canals Fossetto and Fossaccio) have been modified to improve the hydraulic capacity

Through the H2020 project PHUSICOS sedimentation basin have been implemented to prevent runoff of soil and pollutants from farmlands.

Through the H2020 project PHUSICOS buffer strips have been implemented to prevent runoff of pollutants from farmlands. The strips will also prevent runoff of sediments, which also serve as a flood mitigation measure.

AteNas is built around 3 demonstration sites, covering urban and periurban zones of Łódź, Lyon and Vantaa/Helsinki and sharing the challenge of enabling water to citizens and nature, both in terms of quality and quantity.

Utilize of cities water resources to secure regulating ecosystem services, enable Nature-Based Solutions, and enhance adaptive capacity to global changes.
