Daljinsko zaznavanje svetlobne onesnaženosti v Sloveniji

V članku so predstavljeni rezultati analize svetlobne onesnaženosti na območju Slovenije v obdobju 2013-2017. Podatki so pridobljeni s satelita Suomi NPP, ki snema površje Zemlje tudi v nočnem kanalu. Prikazani so rezultati svetlobne onesnaženosti po občinah in trendi svetlobne onesnaženosti v omenjenem obdobju. Posebej so izpostavljena območja z zelo visokimi in nizkimi vrednostmi svetlobne onesnaženosti.

Abstract

Remote sensing of light pollution in Slovenia

The study deals with the problem of light pollution in Slovenia in the period 2013-2017. Remotely sensed data were obtained from the Suomi NPP satellite, which is scanning the earth's surface at night. The findings and geospatial trends of light pollution in the mentioned time period are discussed on the national and municipal levels. Some areas with very high and low levels of light pollution were exposed.

  Title Light Pollution in the Galician Atlantic Islands Maritime-Terrestrial National Park 2018 Report Type Report
  Year 2018 Publication Abbreviated Journal  
  Volume Issue Pages  
  Keywords Conservation; Spain; Galicia; Europe; national park  
  Abstract The Galician Atlantic Islands Maritime-Terrestrial National Park (PNMTIAG), with the exception of the island of Cortegada, still has night skies of acceptable quality. However, the PNMTIAG islands are under strong photic pressures, both internal and external, that hinder the preservation of the basic features of the natural night, and call for an immediate action of all concerned stakeholders

  Title Conservation du ciel nocturne : surveillance de l’éclairage extérieur et de la pollution lumineuse au parc national et à la Réserve internationale de ciel étoilé du Mont-Mégantic Type Journal Article

  Abstract English:

Although seemingly unchanging, today, our ability to see stars on a dark night is in danger of disappearing. The reason for this is the widespread growth of light pollution from inadequate lighting systems. This study, which used a range of methods, presents the results of light pollution measurements taken within the Mont-Mégantic International Dark Sky Reserve (MMIDSR), which was created in 2007 to protect the quality of astronomical observations and research at the Mont-Mégantic Observatory, and to preserve the exceptional starry nightscape visible from the site. Two essential elements of artificial night lighting were considered: its source and its diffusion in the atmosphere. Analyses showed that despite a global trend towards an increase in light levels, population growth on the outskirts of the Parc national du Mont-Mégantic, and the arrival of problematic types of lighting fixtures on the market, the level of light pollution in the MMIDSR has remained stable over the last 10 years, not only at the zenith but across the entire sky.

French:

Pourtant d’apparence immuable, le ciel étoilé est aujourd’hui menacé de disparition. La cause est la croissance généralisée de la pollution lumineuse, résultat de l’utilisation de dispositifs d’éclairage inadéquats. Nous présentons ici les résultats de la mesure de cette pollution obtenue par différentes approches méthodologiques sur le territoire de la Réserve internationale de ciel étoilé du Mont-Mégantic (RICEMM). La RICEMM a été créée en 2007 afin de protéger la qualité des observations astronomiques et de recherche de l’observatoire du mont Mégantic, ainsi que pour conserver les paysages étoilés exceptionnels du site. Deux aspects incontournables de la lumière artificielle nocturne ont été pris en compte : ses sources, ainsi que sa diffusion dans l’atmosphère. Les analyses démontrent que le niveau de pollution lumineuse est resté stable depuis 10 ans dans la RICEMM, tant au zénith que pour l’ensemble du ciel, et ce, malgré une tendance mondiale à la hausse des niveaux d’éclairement, l’augmentation de la population dans la périphérie du parc national du Mont-Mégantic et l’arrivée sur le marché de types de luminaires problématiques.

  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 Yövalaistuksen ja valopäästöjen alueellinen jakautuminen Type Journal Article

  Keywords Remote Sensing  
  Abstract Remotely-sensed night-time lights (NTL) reveal the occurrence of human development while excessive light emissions cause ecological impacts and may create human health hazards. The aim of this research is to find out the factors affecting the quantity of remotely-sensed NTLs in Finland at 2015. We also aim to unveil how much NTLs have changed in Finland from 1993 to 2012 and what is the share of NTLs for different land use types in Finland in 2015. Answers to these questions are achieved with satellite radiance data and data on spatial structure, multiple linear regression (MLR), and change-detection methods. National and regional MLR models were produced to explain NTL and to compare the suitability of this modelling approach in different regions. Radiance is explained by population density, industrial building density, and lit roads density. Surprisingly, the brightest areas in Finland seem to be in Närpiö, a rural area with low population density but where greenhouse farming is common. Based on change-detection, new light sources have emerged because of the expansion of mining and tourism industries.
