The project focuses on the vitality of urban green spaces as a prerequisite for all ecosystem services provided by urban green spaces, especially in those urban areas where the vitality of urban green spaces is particularly endangered by increasing drought and fluctuating precipitation. The challenge is exacerbated by the fact that, in the wake of climate change, the quality and quantity of urban green spaces in densely populated urban districts must be increased for climate-friendly development. A systematic approach with the aim of maintaining sufficient urban green space in a sustainable and vital way is initially dedicated to the question of how much and which green space is needed in a district in order to meet the locally existing and emerging requirements for green infrastructure. In addition, it is necessary to determine which adaptations are necessary and sensible with regard to climate-adapted plant selection. The next step is to identify/cover the needs of water: How much and what water is needed to supply the identified demand for urban green spaces and how can water management be improved?

The project is intended to concretize the concept of "water-sensitive urban design" for the water storage and supply of urban green spaces and to develop exemplary solutions. Nature-based solutions should be implemented where possible and technical solutions where necessary. The project focuses on vital urban greenery and also pursues the goal of low-drain urban districts through decentralised rainwater management. Control variables are esp. the degree of sealing, intermediate storage, climate-adapted plant species. Study areas are quarters in different types of settlement structures. Water availability scenarios will be developed and tested in 6 pilot projects. The product is a district-specific process, action and action guide.

The target group of the tender are bidding consortia with specific expertise, esp. from the fields of urban (redevelopment) planning, urban climatology, hydraulic engineering and urban green maintenance.
