Leipzig BlueGreen II<\/strong> \u2013
Blue-green district development in Leipzig<\/h1>\n<\/div>\n\n\n\n

The city of Leipzig has taken on the challenge of further developing central infrastructures such as the sewage network in a climate-sensitive manner. Advocates of water-sensitive urban development have encouraged a paradigm shift among experts toward decentralized, nature-based solutions. Due to climatic changes such as drought and heavy rainfall, city stakeholders are now committed to implementing resource-efficient transformation of urban neighborhoods.<\/p>\n\n\n\n

According to climate data from the German Meteorological Service (DWD), the city of Leipzig was one of the major German cities with particularly low annual precipitation in 2018 and 2019, resulting in dangerously low soil moisture contents. The amount of plant available water is steadily decreasing and is becoming visible by large tree losses that occurred in 2019 and 2020, where more than 2.000 trees in public green spaces died. At the same time, the city of Leipzig must also respond to an increase in heavy rainfall events which is putting enormous pressure on existing infrastructures, such as networks, as well as on the centralized wastewater treatment plants. These challenges are further exacerbated by a rising degree of sealing due to pending new construction and redevelopment in this rapidly growing city.
<\/p>\n\n\n\n

A major challenge is now to translate political targets and resolutions into municipal action. To this end, concrete measures must be defined for stakeholders, implemented and consolidated in the transformation process.<\/p>\n<\/div>\n\n\n\n

The prospects for implementing the results from Phase 1 are enormous: This applies to both the implementation of the blue-green planning and modelling scenarios, the application of technological solutions obtained therein, and also the co-design processes for the incorporation of the results by the city of Leipzig. A high participation in our workshops and the numerous nationwide interview requests have shown the overall interest in the research topic and in an adoption of the results at other locations.<\/p>\n<\/div>\n\n\n\n

The 3rd BlueGreen Dialogues on March 22, 2023, held as part of the public status seminar of the BMBF joint project Leipzig BlueGreen, presented key results of the first project phase from the German model city for „resource-efficient urban districts“.

The developed scenarios and technologies for the planned new neighbourhood to be constructed, as well as existing neighbourhoods will serve as a blueprint for other locations. Findings of the project are being recognized beyond the state of Saxony. Recommendations for action for a paradigm shift in urban water management have also been developed at the federal level.

Anchoring blue-green urban development throughout Leipzig and beyond<\/strong><\/strong><\/strong>
Valuable communication structures were established in Phase 1, which are now being expanded as a model in the so-called „Kolonnadenviertel<\/em>“ as part of the upcoming portfolio renovation of the Leipzig Housing Association (LWB). At the same time, planning and decision-making processes for the entire city are being optimized by preparing potential analyses for investment planning for the bluegreen retrofitting of existing neighbourhoods. In addition to the evaluation of public properties, the preparation of a Leipzig action plan for the future use of blue-green investments is of great importance. The continuation beyond the project duration is ensured by the support of the inter-agency steering committee for „water-sensitive urban development“. The Committee evaluates, prioritizes, and prepares implementations for the blue-green urban development. In the second phase of the project, the necessary organizational and legal framework conditions will be developed, evaluated and introduced as recommendations for political decision-making processes. <\/p>\n\n\n\n
