Explain a use case of EO for smart cities, e.g. how EO derived information about urban green instrastructure supports designing nature based solutions for preserving ecosystem services
The users in smart cities are multiverse and include large number of profiles. This include urban planners, architects, spatial planning offices, urban policy makers, transportation/environment/health departments but also citizen themselves.
The users benefit from additional information and knowledge extracted from EO data. This information and knowledge can help them to better tackle with challenges arising from climate change and urbanization. As each urban area is unique, EO can provide relevant information by detecting, evaluating and measuring these localities.
This EO based information can be extracted on one occasion or continuously, benefiting from revisiting satellites. EO can support investigation of archive data to extract trends or by investigating current state to set a baseline. This baseline is then further used to monitor the changes or to assess the impact of different decisions and actions. In most cases, this information is further used in various GIS analyses or modelling procedures.
The topics where EO can contribute are as follows: urban land cover, urban heat islands, air/water/soil quality, tree/vegetation health, detection of invasive vegetation species, damage detection on buildings or infrastructure, development of infrastructure and many more.
As listed, EO can support various domains that can be fitted under Nature-based solutions (NBS). NBS have been gaining attention as multifunctional solutions that may help cities to address challenges arising from climate change and urbanization.
The concept of Nature-based Solutions (NBS) has evolved as an umbrella concept embracing concepts such as green/blue/nature infrastructure, ecosystem approach, ecosystem services or natural systems agriculture, natural solutions, ecosystem-based approaches, and ecological engineering. NBS can include solutions such as water purification, reduction of flood risk, or deliberate efforts to decrease temperature and improve air quality.
