  Title LOCALIZED LIGHT SENSORY IN RELATION TO GRAZING ACTIVITY OF ECHINOMETRA MATHAEI Type Journal Article
  Year 2018 Publication Abbreviated Journal  
  Volume Issue Pages  
  Keywords Animals  
  Abstract This paper offers insight on the regulation of nocturnal behavior in burrowing sea urchin Echinometra mathaei of the Pacific. While it is known E. mathaei maintains nocturnal hours of activity (primarily grazing, burrowing, and locomotion), it is unknown whether this pattern follows a circadian rhythm or responds to local conditions of darkness. Varying light treatments were tested to determine potential manipulation of active behavior and explore potential for habitat destruction. Light manipulation was used to determine the role light sensory plays in the regulation of normal behavior. First utilizing gradual manipulation and later utilizing sudden manipulation to differentiate response to light stimuli. It was determined that while E. mathaei maintains nocturnal

activity via localized light sensory, manipulation of latent hours could not be significantly reproduced. It was found that while light manipulation can be responsible for simulating hours of activity, light manipulation cannot replicate latent hours. Upon exploration of predator response capability in E. mathaei following manipulation, it was found that individuals exposed to prolonged periods of artificial light had slower predation response times than individuals acclimated to a regular pattern of light exposure. These findings connect potential habitat degradation via grazing behaviors of E. mathaei to anthropogenic activity in Mo’orea, French Polynesia.

  Title Roadway Lighting Retrofit: Environmental and Economic Impact of Greenhouse Gases Footprint Reduction Type Journal Article
  Year 2018 Publication Sustainability Abbreviated Journal Sustainability  
  Volume 10 Issue 11 Pages 3925  
  Keywords Economics; Lighting  
  Abstract Roadway lighting retrofit is a process continuously developed in urban environments due to both installation aging and technical upgrades. The spectacular example is replacing the high intensity discharge (HID) lamps, usually high pressure sodium (HPS) ones, with the sources based on light-emitting diodes (LED). The main focus in the related research was put on energy efficiency of installations and corresponding financial benefits. In this work, we extend those considerations analyzing how lighting optimization impacts greenhouse gas (GHG) emission reduction and what are the resultant financial benefits expressed in terms of emission allowances prices. Our goal is twofold: (i) obtaining a quantitative assessment of how a GHG footprint depends on a technological scope of modernization of a city HPS-based lighting system; and (ii) showing that the costs of such a modernization can be decreased by up to 10% thanks to a lowered CO 2 emission volume. Moreover, we identify retrofit patterns yielding the most substantial environmental impact.

  Title Experimental Study of the Levels of Street Lighting Using Aerial Imagery and Energy Efficiency Calculation Type Journal Article
  Year 2018 Publication Sustainability Abbreviated Journal Sustainability  
  Volume 10 Issue 12 Pages 4365  
  Keywords Remote Sensing; Lighting  
  Abstract This article describes an innovative method for measuring lighting levels and other lighting parameters through the use of aerial imagery of towns and cities. Combined with electricity consumption data from smart electricity meters, it was possible to measure the energy efficiency of public lighting installations. The results of this study also confirmed that lighting measurements, installation material, luminaire position, and electricity consumption data can be easily integrated into geographic information systems (GIS). The main advantage of this new methodology is that it provides information about lighting installations in large areas in less time than more conventional procedures. It is thus a more effective way of obtaining the data required to calculate the energy efficiency of lighting levels and electricity consumption. There is even the possibility of generating street lighting maps that provide local administrations with up-to-date information regarding the status of public lighting installations in their city. In this way, modifications or improvements can be made to achieve greater energy savings and, if necessary, to correct the distribution or configuration of public lighting systems to make them more efficient and sustainable. This research studied levels of street lighting and calculated the energy efficiency in various streets of Deifontes (Granada), through the use of aerial imagery.

  Title Factors influencing Manx Shearwater grounding on the west coast of Scotland Type Journal Article
  Year 2018 Publication Ibis Abbreviated Journal Ibis  
  Volume 160 Issue 4 Pages 846-854  
  Keywords Animals  
  Abstract Grounding of thousands of newly fledged petrels and shearwaters (family Procellariidae) in built‐up areas due to artificial light is a global problem. Due to their anatomy these grounded birds find it difficult to take off from built‐up areas and many fall victim to predation, cars, dehydration or starvation. This research investigated a combination of several factors that may influence the number of Manx Shearwater Puffinus puffinus groundings in a coastal village of Scotland located close to a nesting site for this species. A model was developed that used meteorological variables and moon cycle to predict the daily quantity of birds that were recovered on the ground. The model, explaining 46.32% of the variance of the data, revealed how new moon and strong onshore winds influence grounding. To a lesser extent, visibility conditions can also have an effect on grounding probabilities. The analysis presented in this study can improve rescue campaigns of not only Manx Shearwaters but also other species attracted to the light pollution by predicting conditions leading to an increase in the number of groundings. It could also inform local authorities when artificial light intensity needs to be reduced.

  Title Detecting spatial pattern of inequalities from remote sensing – Towards mapping of deprived communities and poverty Type Journal Article
  Year 2018 Publication EUR 29465 EN Abbreviated Journal  
  Volume Issue Pages JRC113941  
  Keywords Remote Sensing  
  Abstract Spatial inequalities across the globe are not easy to detect and satellite data have shown to be of use in this task. Earth Observation (EO) data combined with other information sources can provide complementary information to those derived from traditional methods. This research shows patterns of inequalities emerging by combining global night lights measured from Earth Observation, population density and built-up in 2015. The focus of the paper is to describe the spatial patterns that emerge by combing the three variables. This work focuses on processing EO data to derive information products, and in combining built-up- and population density with night-time lights emission. The built-up surface was derived entirely from remote sensing archives using artificial intelligence and pattern recognition techniques. The built-up was combined with population census data to derive population density. Also the night-time lights emission data were available from EO satellite sensors. The three layers are subsequently combined as three colour compositions based on the three primary colours (i.e. red, green and blue) to display the “spatial human settlement pattern” maps. These GHSL nightlights provide insights in inequalities across the globe. Many patterns seem to be associated with countries income. Typically, high income countries are very well lit at night, low income countries are poorly lit at night. All larger cities of the world are lit at night, those in low-income countries are often less well lit than cites in high-income countries. There are also important differences in nightlights emission in conflict areas, or along borders of countries. This report provides a selected number of patterns that are described at the regional, national and local scale. However, in depth analysis would be required to assess more precisely that relation between wealth access to energy and countries GDP, for example. This work also addresses regional inequality in GHSL nightlights in Slovakia. The country was selected to address the deprivation of the Roma minority community. The work aims to relate the information from the GHSL nightlights with that collected from field survey and census information conducted at the national level. Socio-economic data available at subnational level was correlated with nightlight. The analysis shows that despite the potential of GHSL nightlights in identifying deprived areas, the measurement scale of satellite derived nightlights at 375 x 375 m to 750 x 750 m pixel size is too coarse to capture the inequalities of deprived communities that occur at finer scale. In addition, in the European context, the gradient of inequality is not strong enough to produce strong evidence. Although there is a specific pattern of GHSL nightlights in settlements with high Roma presence, this cannot be used to identify such areas among the others. This work is part of the exploratory data analysis conducted within the GHSL team. The exploratory analysis will be followed by more quantitative assessments that will be available in future work.
