The CLEVER Way: Hamburg, Neugraben-Fischbek

The CLEVER Cities project identified the primary planning goals for Neugraben-Fischbek district located in the South-West of the city of Hamburg was to: (a) creating a connective ‘Green Corridor’ to link a system of NbS interventions; (b) establishing horizontal greenery through the construction of green roofs on existing buildings; and (c) address the topic of environmental education and connect the youth with nature. 

Hamburg has aimed at addressing the following challenges, including:

  • Increase biodiversity and nature in the city: To address this, the city

NBSEduworld Case Study: ReDuna Project – Ecological restoration of sand dunes at São João da Caparica and Cova do Vapor beaches

Almada municipality:Ecological restoration of a coastal sand dunes ecosystem

The ReDuna project aims to restore the natural capacity of the Almada sand dune ecosystem to healthily respond to natural drivers, enhancing its resilience to sea level rise and storms, and providing an excellent teaching tool to demonstrate, in a practical way, the benefits of nature-based solutions to both residents and visitors of this beach area.

Multi-criteria decision analysis in an urban planning and storm water management case in the Kivistö case, City of Vantaa, Finland

Evaluation framework in MCDA

The objectives of the case were to i) develop a systematic and interactive approach to support multi-objective urban planning in general and ii) to demonstrate the approach in the Kivistö sketch area in developing and evaluating alternatives for urban planning and decentralised stormwater management.

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).

VALLADOLID (SPAIN) – RE-NATURING URBAN PLAN WITH NBS

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...

Buffer strips along canals in the area of Lake Massaciuccoli

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 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.

Skurdalsåa flood retention

The existing old dam at Lake Svintjønna. The measures will increase the dam height by ca. 0.5 m and establish a new gate and threshold, with automatic monitoring of the lake level.

The Skurdalsåa River is one of many steep tributary rivers to the main river Gudbrandsdalslågen. The river has its outlet from an old dam (1870) in Lake Svintjønna. Due to the relatively small catchment, Skurdalsåa responds rapidly to precipitation and snow melt. Roads, houses, a school, a kindergarten, and a sports facility are situated adjacent to the lower part of the river. The infrastructure has experienced repeated flood damage in recent years.

Through the H2020 project PHUSICOS an old dam has been modified in order to reduce the peak flood.
