  Title Modelling of light pollution in suburban areas using remotely sensed imagery and GIS Type Journal Article
  Year 2006 Publication Journal of Environmental Management Abbreviated Journal J Environ Manage  
  Volume 79 Issue 1 Pages 57-63  
  Keywords Remote Sensing; Air Pollutants/*analysis; Cities; Environmental Monitoring/*methods; *Geographic Information Systems; Greece; Humans; *Light; Models, Theoretical; *Suburban Health  
  Abstract This paper describes a methodology for modelling light pollution using geographical information systems (GIS) and remote sensing (RS) technology. The proposed approach attempts to address the issue of environmental assessment in sensitive suburban areas. The modern way of life in developing countries is conductive to environmental degradation in urban and suburban areas. One specific parameter for this degradation is light pollution due to intense artificial night lighting. This paper aims to assess this parameter for the Athens metropolitan area, using modern analytical and data capturing technologies. For this purpose, night-time satellite images and analogue maps have been used in order to create the spatial database of the GIS for the study area. Using GIS advanced analytical functionality, visibility analysis was implemented. The outputs for this analysis are a series of maps reflecting direct and indirect light pollution around the city of Athens. Direct light pollution corresponds to optical contact with artificial night light sources, while indirect light pollution corresponds to optical contact with the sky glow above the city. Additionally, the assessment of light pollution in different periods allows for dynamic evaluation of the phenomenon. The case study demonstrates high levels of light pollution in Athens suburban areas and its increase over the last decade.

  Title Le socioécosystème environnement nocturne : un objet de recherche interdisciplinaire Type Journal Article

  Abstract Résumé

Cet article expose le cheminement par lequel nous constituons lʼenvironnement nocturne en objet de recherche interdisciplinaire. Apparue dans les années 1990 suite à la requalification environnementale de lʼéclairage urbain en pollution lumineuse, cette notion floue vise à appréhender les systèmes – humains ou non – fonctionnellement liés à la nuit et à lʼobscurité. En nous appuyant sur lʼobservation des processus de construction, de légitimation et de territorialisation de lʼenvironnement nocturne, nous montrons que cette notion opère une jonction entre différentes acceptions et approches fortement cloisonnées des rôles, fonctions et effets de lʼéclairage artificiel nocturne (ALAN, pour artificial light at night1). Nous proposons dʼaborder son étude suivant le cadre dʼanalyse des socioécosystèmes qui nécessite la mise en interaction des différentes approches de lʼALAN par les sciences de la société et les sciences du vivant.

Abstract

This paper explains the scientific reasoning that led us to institute the “night environment” as new interdisciplinary research topic from a social-ecological perspective. Sociocultural, ecological and health costs of artificial light at night (ALAN) have been gradually highlighted since the second half of the twentieth century in a range of scientific fields, from astronomy to medicine through ecology and energy. At the same time an environmentalist movement was emerging: the “dark-sky movement” which condemns “light pollution” and carries its demands within local, national or international arenas. In the 1990s, the requalification of urban lighting as light pollution gave rise to the ill-defined notion of night environment. This notion aims to understand the systems, both human and non-human, that are functionally related to the night and darkness. Building on medium and long-term observations of the processes of construction, legitimation and territorialization of the nocturnal environment, we demonstrate that this notion enables to establish a junction between the different strongly compartmentalized meanings and approaches of the roles, functions and effects of ALAN, and more specifically of urban lighting. We propose to approach its study based on the social-ecological systems framework. This requires creating strong interactions between the different approaches of ALAN: those of the social sciences and those of the experimental, life and health sciences.

  Title Concilier éclairage urbain et environnement nocturne : Les enjeux d’une controverse sociotechnique Type Journal Article
  Year 2014 Publication Natures Sciences Sociétés Abbreviated Journal Nat. Sci. Soc.  
  Volume 22 Issue 4 Pages 317-328  
  Keywords History; Energy; Planning; Regulation; Society  
  Abstract La question de l’éclairage urbain nocturne est posée publiquement de manière de plus en plus significative, d’abord aux États-Unis puis en Europe. Cantonnée à l’origine au domaine de l’astronomie, cette question pose problème dans différents secteurs : l’environnement, la santé, l’urbanisme, mais aussi et surtout l’énergie... En croisant une approche sociologique avec une approche géographique, les auteurs font le récit d’une controverse environnementale aboutissant, en France, à l’inscription de la notion de pollution lumineuse dans la loi Grenelle et questionnent sa dimension spatiale. Ils montrent les différentes logiques et interprétations, à l’œuvre autour de la distinction entre « pollution » et « nuisance » lumineuses, qui traversent les scènes de négociation sur les processus de normalisation et la mobilisation d’outils de zonage.

  Title Testing of Various Monochromatic LED Lights Used in Supplemental Irradiation of Lettuce in Modern urban Rooftop Polytunnels Type Journal Article
  Year 2019 Publication Applied Engineering in Agriculture Abbreviated Journal  
  Volume Issue Pages  
  Keywords Plants  
  Abstract Urban farming could provide both vegetable growers and urban dwellers in general with more direct access to various fresh vegetables. Nevertheless, certain challenging problems associated with urban farming, including a lack of cultivation space and the effects of urban heat islands, must still be solved. Relatedly, a grower must, in some cases, also know how to utilize various forms of technology, such as lighting systems, as well as factors such as water availability. In this study, an original rooftop polytunnel design for lettuce (Lactuca sativa cv. Lollo Rosso) cultivation equipped with a hydroponic system and light emitting diodes (LEDs) is proposed. Various monochromatic lights were also tested for their effects on different quality parameters of lettuce. Specifically, supplemental red (655 nm), blue (445 nm), green (520 nm), and ultraviolet (380 nm) LED lights were used at night to apply photon fluxes of 150, 150, 150, and 20 μmol.m-2.s-1, respectively. The resulting effects of these different colored LEDs on the pigment concentration and growth response of the lettuce grown inside the roof polytunnel were then investigated. The experiment was then repeated several times with different environmental parameters in order to compare the effects of the different light wavelengths under higher temperatures and higher natural irradiation conditions.The results indicated that supplemental red or blue light at night could be strategically employed to maintain low nitrate levels and enhance the nutritional value and growth of lettuce grown in roof polytunnels.

  Title A Novel Method of Evaluating Highway Traffic Prosperity Based on Nighttime Light Remote Sensing Type Journal Article
  Year 2020 Publication Remote Sensing Abbreviated Journal Remote Sensing  
  Volume 12 Issue 1 Pages 102  
  Keywords Remote Sensing  
  Abstract As the backbone and arteries of a comprehensive transportation network, highways play an important role in improving people’s living standards and promoting economic growth. However, globally, there is limited quantifiable data evaluating the highway traffic state, characteristics, and performance. From the 1960s to the present, remote sensing has been regarded as the most effective technology for long-term and large-scale monitoring of surface information. However, how to reflect the dynamic “flow” information of traffic with a static remote sensing image has always been a difficult problem that is hard to solve in the field. This study aims to construct a method of evaluating highway traffic prosperity using nighttime remote sensing. First, based on nighttime light data that indicate social and economic activities, a highway-oriented method was proposed to extract highway nighttime light data from 2015 annual nighttime light data of the Suomi National Polar-Orbiting Partnership Visible Infrared Imaging Radiometer Suite sensor (SNPP-VIIRS). Subsequently, Pearson correlation analysis was used to fit the relationship between freeway traffic flow volume and freeway nighttime light at the provincial level. The results showed that Pearson Correlation Coefficient of freeway nighttime light and freeway traffic flow volume for coach and truck are 0.905 and 0.731, respectively, which are higher than between freeway traffic flow volume for coach and truck and total nighttime light (0.593 and 0.516, respectively). A new index—Highway Nighttime Traffic Prosperity Index (HNTPI)—was proposed to evaluate highway traffic across China. The results showed that HNTPI has a strong correspondence with socio-economic parameters. The Pearson Correlation Coefficient of HNTPI and gross domestic product (GDP) per capita, consumption per capita, and population are 0.772, 0.895, and 0.968, respectively. There is a huge spatial heterogeneity in China nighttime traffic, the prosperity degree of highway traffic in developed coastal areas is obviously higher than that inland. The national general highway is the most prosperous highway at night and the national general highway nighttime prosperity of Shanghai reached 22.34%. This research provides basic data for the long-term monitoring and evaluation of regional traffic operation at night and research on the correlation between regional highway construction and the economy.
