| Popis: | The threats posed by climate variability and change have spurred the development of several innovative geoengineering techniques, including nature-based solutions. This involves the manipulation or imitation of natural systems within and around urban grey infrastructure, to mitigate anthropogenic impacts. Recent studies have proposed nature-based solutions as a possible strategy for both mitigation and adaptation against climate variability and change. Several studies observed a cooling effect through nature-based solutions which mayinfluencethe urban heat island effect. The significance of this geoengineering technique on the urban microclimate has, however, not yet been well-established. Subsequently, this study seeks to investigate the significance of nature-based solutions in affecting the urban microclimate. Specifically, this study conducts a comparison of the surface temperatures in select urban areas with those in the surrounding rural environment. The temperatures are determined by examining ground-based observations from weather stations.Additionally, these urban areas are classified according to their vegetation cover, and the results for the identified green and grey cities are compared to determine whether significant differences in surface temperature exist. The findings of this study may be used to inform spatial decision-making in relation to the application of nature-based solutions as a potential geoengineering approach to mitigating climate variability and change.Keywords: Climate variability, Nature-based solutions, Urban micro-climate, Surface temperature The 28th IUGG General Assembly (IUGG2023) (Berlin 2023) |
