Climate change adaptation via urban green infrastructure (UGI) can significantly reduce the UHI effect while at the same time contribute to mitigation by reducing energy demands. Still these different goals are rarely considered together. The project “Climate Mitigation and Urban Green Infrastructure” at the “Centre for Urban Ecology and Climate Change Adaptation” addresses these challenges by developing integrated strategies for urban planning. While climate policies are agreed at (inter-)national level, it is the local level that needs to translate these goals into action. With a comparative analysis of three Bavarian case studies, the opportunities and challenges local governments face for implementing climate policies into planning are identified. In order to translate national policies into strategies at the local level this research creates new knowledge and novel tools to develop and implement strategies for climate change mitigation and adaptation.

The project examines synergies of different green infrastructure measures with quantitative analyses of climate regulating effects and residential energy demand reductions. In qualitative studies also the effects on biodiversity and quality of open space are considered. Furthermore, the project analyses the capacities of local governments and the legal leeways for implementing of climate change related measures into urban planning. Besides the synergies between mitigation and adaptation it also aims to identify how integrated planning for climate change can enhance general strategies for urban development.

The analyses are conducted for three case studies, which each represent a typical urban fabric: perimeter blocks, row housing and historic city centres. With this, the applicability of the investigated green infrastructure measures in other communities than the investigated ones shall be ensured.

Based on its results, the project gives recommendations to promote the implementation of multifunctional green infrastructure for mitigation and adaptation.
This research approach was presented at the 1st European Green Infrastructure Conference held from November 23 to 24 2015 in Vienna. In a working group on “Links between climate change adaptation, urban heat islands and reduced energy demand via green infrastructure” conference participants had the chance to discuss this topic and share their experiences and lessons learned. Two points got special attention during the discussion: Tackling the issues of climate change mitigation and adaptation requires very different approaches due to temporal and spatial issues. Interdisciplinary thinking in synergies and co-benefits for also other sectors of urban planning provides a great potential for convincing stakeholders to implement green infrastructure measures. Moreover, the methodological approach of urban fabric types was seen as useful for translating results to other cities with similarities in their urban structure and hence similar opportunities to implement green infrastructure.
