    Mapping the Invisibles: Global Urban Inequalities through Night Lights (2023)
    In:  Proceedings

    Description: Intra-urban poverty mapping using Earth Observation is primarily limited to daylight studies. Its present scope does not reveal several facets of urban poverty, such as access to reliable and sustainable energy for all (SDG-7). Most of our current knowledge of artificial light at night comes from datasets generated by a limited number of remote sensing missions, mostly low spatial and spectral resolution sensors and images from the International Space Station (ISS). The latter offers greater spectral and spatial resolution but is not routinely acquired for most parts of the globe. Although there are currently automatic methods for their calibration, they continue to present limitations that make them a non-ideal instrument for global monitoring of the multiple dimensions of urban poverty. Therefore, this study provides an overview of the multiple dimensions of poverty and its scope to be observed through nighttime light remote sensing imagery. We define user requirements for upcoming satellite-based sensors to support global urban poverty mapping in the context of the ongoing European Space Agency-funded research project called NightWatch

    Monitoring, trends and impacts of light pollution (2024)
    In:  Nature Reviews Earth and Environment
    Details
    Publication Date: 2024-05-29
    Description: Light pollution has increased globally, with 80% of the total population now living under light-polluted skies. In this Review, we elucidate the scope and importance of light pollution and discuss techniques to monitor it. In urban areas, light emissions from sources such as street lights lead to a zenith radiance 40 times larger than that of an unpolluted night sky. Non-urban areas account for over 50% of the total night-time light observed by satellites, with contributions from sources such as transportation networks and resource extraction. Artificial light can disturb the migratory and reproductive behaviours of animals even at the low illuminances from diffuse skyglow. Additionally, lighting (indoor and outdoor) accounts for 20% of global electricity consumption and 6% of CO2 emissions, leading to indirect environmental impacts and a financial cost. However, existing monitoring techniques can only perform a limited number of measurements throughout the night and lack spectral and spatial resolution. Therefore, satellites with improved spectral and spatial resolution are needed to enable time series analysis of light pollution trends throughout the night.
