NaMaRes 2.0 –
Digital urban resource management in districts
The sustainability and resilience of existing urban districts are moving into the focus of political and social attention. The pressure to use existing resources and potentials calls for an integrated, resource-efficient development of districts, urban transformation, and concrete solutions. The namares projects aim to digitally support the integrated planning and transformation process at the district level. The software developed in the first phase will be tested and developed in several test areas and municipal planning processes.
Sustainable cities and municipalities
Cities are in a constant state of change. This process is driven by society’s desire for modern, sustainable, and liveable places to live and work. It is also driven by the megatrends of climate change, resource scarcity, demographic change, and globalisation.
SDG 11 aims to make cities and communities more inclusive, safe, resilient, and sustainable. The involvement of civil society and many other stakeholders is crucial to the success of this transformation. The contribution of cities to sustainable development is, therefore, a complex management task. The challenges are particularly significant in existing and historically grown urban areas and districts.
This project aims to develop and digitally support (through software) an integrated planning and transformation process at the district level to transform existing districts into sustainable, resource-efficient urban districts.
Digital support for urban development
In the first phase of funding, the basics and a prototype software application were developed for assessing the current state of urban districts and for conceptualising sustainability measures and assessing their potential. Tools were developed for district-level information processing (e.g., recording and mapping of ecosystem services) and decision support (e.g., a software application for district assessments), indicators for resource efficiency at the district level and guidelines for operationalising development strategies. The project results contribute greatly to improving the information base on existing districts regarding resource availability and use. These results make an important contribution to the operationalisation and local implementation of SDG 11.
The tools and software application have a very granular work structure, allowing conclusions to be drawn about individual land plots and building surfaces. The tools use existing urban data on buildings and land use as a basis for operation. Data quality on public spaces in a district is good, but data on private green spaces is lacking. These have been collected and evaluated for a comprehensive description of ecosystem services.
A software application and a web tool for digital data processing were developed. These tools map and evaluate nine different sustainability measures. The developed model individually assesses these measures with 12 main indicators for each plot and sub-area. For each measure, a specific technically feasible potential is simulated for implementation in the identified areas, and the effects are determined and economically evaluated (in euros).
The results can be retrieved for each sub-area, plot, building block, or district. This makes it possible to identify potential improvements (‘hotspots’) with particularly high cost-benefit ratios in the existing context and estimate the environmental impact and the initial and ongoing costs of possible measures.
From proof-of-concept to practical use
In the follow-up phase, namares 2.0, the developed tools will be extensively tested in practice and further developed according to user needs. The application will be tested in several municipalities (Cologne, Bruchsal and Bretten) to demonstrate how it can support formal urban planning and development processes and to ensure its transferability. Plausibility analyses and validations will be conducted, and workshops with municipalities and urban planners will be held to develop additional functionalities and measures. The implementation and institutionalisation phase aims to permanently use the software application and the guide in the participating municipalities for the continuous and digital support of urban resource management. To achieve this goal, the software prototype’s current Technology Readiness Level (TRL) will be increased from 3-4 to 6-7. For dissemination purposes, introductory courses will be offered to other interested municipalities.
