Title Assessing the effects of artificial light at night on biodiversity across latitude – Current knowledge gaps Type Journal Article
Year 2019 Publication Global Ecology and Biogeography Abbreviated Journal Global Ecol Biogeogr
Volume in press Issue Pages geb.13037
Keywords Ecology; biodiversity; Review
Abstract Aim

Exposure to artificial light at night (ALAN) is a risk factor for organisms. Considering the spread and increasing intensity of night brightness across the globe, and the key role of light at all biological levels, alterations of ecosystems are expected. Yet, we cannot predict the severity of the effects of ALAN in several biomes because little information is available outside the temperate zone. We reviewed current knowledge and identified traits that could be targeted to fill this knowledge gap in order to contribute to the elaboration of a biogeographical framework for the study of ALAN at the global scale.

Location

Global.

Time period

Current and next decades.

Methods

We analysed the latitudinal variation in ALAN and focused on environmental factors that vary with latitude but that have been overlooked. We reviewed biological traits that exhibit latitudinal variation and depend on light and photoperiod and compiled information about the predicted changes in human demography and road networks across different world regions.

Results

Cloud cover amplifies ALAN far away from urbanized areas. Because of the higher frequency of overcast sky nights, exposure effects may be stronger both at high latitudes and across a large fraction of the intertropical zone, although at different times of the year. Intertropical biomes host the largest fraction of global biodiversity. Although currently they are not the most exposed to ALAN, their human populations are growing, and urbanized areas and road networks are expanding. Hence, ALAN could have strong ecological consequences, with cloud cover as an aggravating factor.

Perspectives

Knowledge gaps currently limit our ability to predict the effects of ALAN in different biomes. Therefore, it will be important to start investigating the consequences of this novel environmental factor across the globe, in order to develop a relevant theoretical framework.

Title What do night satellite images and small-scale grid data tell us about functional changes in the rural-urban environment and the economy? Case studies Frankfurt-Rhein/Main and Ljubljana Urban Region Type Journal Article
Year 2018 Publication Abbreviated Journal
Volume Issue Pages
Keywords Remote Sensing
Abstract This study addresses how nocturnal satellite imagery can be used in spatial analysis of rural-urban relations. It shows how a novel approach can be used to complement the prevalent traditional survey methods below the data resolution level of official regional statistics. The overarching aim is to contribute with a novel database and different empirical tools to broaden spatial information for decision-making in policy and planning at small spatial scale amongst municipalities. The accuracy of spatial information is expected to be substantially enhanced, paving ways for better rural-urban planning coordination and synergies.

Title An investigation of LED street lighting's impact on sky glow Type Journal Article
Year 2017 Publication Abbreviated Journal
Volume PNNL-26411 Issue Pages
Keywords Skyglow; Lighting
Abstract A significant amount of public attention has recently focused on perceived impacts of converting street lighting from incumbent lamp-based products to LED technology. Much of this attention pertains to the higher content of short wavelength light (commonly referred to as “blue light”) of LEDs and its attendant influences on sky glow (a brightening of the night sky that can interfere with astronomical observation and may be associated with a host of other issues). The complexity of this topic leads to common misunderstandings and misperceptions among the public, and for this reason the U.S. Department of Energy Solid-State Lighting Program embarked on a study of sky glow using a well-established astronomical model to investigate some of the primary factors influencing sky glow. This report details the results of the investigation and attempts to present those results in terms accessible to the general lighting community. The report also strives to put the results into a larger context, and help educate interested readers on various topics relevant to the issues being discussed.

Title Tackling Social Inequalities in Public Lighting Type Journal Article
Year 2016 Publication Abbreviated Journal
Volume Issue Pages
Keywords Society
Abstract 2This report is based on research findings of the Configuring Light/Staging the Social research programme (CL) based at the London School of Economics and Political Science (LSE), as well as on discussions of the Configuring Light expert working group. Consisting of high-profile experts and stakeholders in the fields of design, planning and policy-making, this group was established by CL to develop a new agenda for tackling social inequalities in public lighting. Members of the working group are listed at the end of this document.This project was run by the LSE-based Configuring Light/Staging the Social research programme and funded by LSE Knowledge Exchange and Impact funding.
