  Title Tropical Shearwater population stability at Reunion Island, despite light pollution Type Journal Article
  Year 2017 Publication Journal of Ornithology Abbreviated Journal J Ornithol  
  Volume 158 Issue 2 Pages 385-394  
  Keywords Animals  
  Abstract Seabirds are exposed to numerous threats at sea and on land, and they are among the most endangered birds worldwide. Procellariids are attracted by artificial light, and this causes massive fallout at various places of the world. In Reunion Island, Tropical Shearwaters Puffinus bailloni are heavily impacted by light pollution. To assess the population trends of this species, we conducted two large-scale acoustic surveys across the island (in 1996/1997 and in 2013/2015) and analysed the numbers of birds attracted by lights and rescued by the local wildlife rescue center between 1996 and 2015. We detected 220 colonies in 2013/2015, including 124 colonies previously surveyed in 1996/97 and 96 newly discovered colonies. The average vocal activity recorded at colonies was similar during the two surveys suggesting no marked change in population size. Some 13,200 Tropical Shearwaters were found grounded since 1996 due to light attraction, of which 88 % were successfully released. The number of reported grounded birds increased 19-fold between 1996 and 2015. This increase was due to a combination of factors that are difficult to disentangle: (1) increasing public awareness; (2) increasing light pollution; and (3) the absence of population collapse. Indeed, both acoustic surveys and the number of rescued birds indicate that the Tropical Shearwater population of Reunion Island did not decline between 1996/1997 and 2013/2015. We suggest that the rescue campaigns conducted annually strongly contributed to this stability. Thus, we recommend maintaining the rescue operations, but also to reduce light pollution.

  Title Paving the planet: impervious surface as proxy measure of the human ecological footprint Type Journal Article
  Year 2009 Publication Progress in Physical Geography: Earth and Environment Abbreviated Journal Progress in Physical Geography: Earth and Environment  
  Volume 33 Issue 4 Pages 510-527  
  Keywords Remote Sensing  
  Abstract Fundamental questions regarding the human-environment-sustainability problematic remain contested. What are the relative roles of population, consumption, and technology with respect to sustainability? How can sustainability be measured? Numerous metrics have been developed to address these controversial questions including ideas of carrying capacity, environmental sustainability indices, and ecological footprints. This work explores the question: is pavement a proxy measure of human impact on the environment? We explore and evaluate the use of satellite derived density grids of constructed area (aka ‘pavement’ or ‘impervious surface’) in the calculation of national and subnational ‘ecological footprints’. We generated a global constructed area density grid for the 2000—2001 period using satellite observed nighttime lights and a population count grid from the US Department of Energy. Satellite data inputs to the population product include MODIS landcover, SRTM topography and high-resolution imagery. Calibration of the global constructed area density product was derived from high-resolution aerial photographs. We demonstrate that a satellite derived constructed area per person index can serve as a proxy measure of ecological footprints at both the national and subnational level. This relatively simple and globally uniform measure of human impact on the environment correlates strongly with other more difficult to obtain measures.

  Title Light pollution and seabird fledglings: Targeting efforts in rescue programs: Assessing Condition Of Rescued Seabirds Type Journal Article
  Year 2017 Publication The Journal of Wildlife Management Abbreviated Journal Jour. Wild. Mgmt.  
  Volume 81 Issue 4 Pages 734-741  
  Keywords Animals  
  Abstract One of the most critical phases in the life of petrels (Procellariiformes) is at fledging whenyoung birds pass from parental dependence on land to an independent life at sea. To mitigate mortality at thistime, rescue programs are implemented near breeding sites around the world, especially for birds grounded byartificial lights. We evaluated the plumage and body condition of short-tailed shearwater (Ardennatenuirostris) fledglings captured at colonies just before departure in comparison to fledglings washed up onbeaches and to fledglings attracted by artificial light along roads. We measured abundance of down, bodymass, and body condition index as the standardized residuals of a regression of body mass on size, andemployed linear models to test differences on body mass and body condition between locations. Beach-washed birds were underweight and in poor condition, suggesting their future survival probabilities at seawere low. Birds rescued on roads as a consequence of light attraction had lower body weights and conditionindices than fledglings captured at the colony. However, more than 50% of light-attracted birds had attainedsimilar weights to those of adults, suggesting they have higher probabilities of survival than beach-washedbirds. Water-logged birds being washed onto beaches is a natural process, but birds grounded by lightingalong roads is an increasing anthropogenic threat that requires management. Thus, management andconservation efforts should be directed to protect birds in the colonies and reduce light-induced mortality,ideally through the strategic reduction of light sources and lateral light spillage. When resources forconservation are limited, rescue programs should focus on rescuing birds from roads rather than beach-washed birds, which have a lower probability of survival.

  Title Shedding Light on the Global Distribution of Economic Activity Type Journal Article
  Year 2010 Publication The Open Geography Journal Abbreviated Journal Togeogj  
  Volume 3 Issue 1 Pages 147-160  
  Keywords Economics; Remote Sensing  
  Abstract Collection of data on economic variables, especially sub-national income levels, is problematic, due to various shortcomings in the data collection process. Additionally, the informal economy is often excluded from official statistics. Nighttime lights satellite imagery and the LandScan population grid provide an alternative means for measuring economic activity. We have developed a model for creating a disaggregated map of estimated total (formal plus informal) economic activity for countries and states of the world. Regression models were developed to calibrate the sum of lights to official measures of economic activity at the sub-national level for China, India, Mexico, and the United States and at the national level for other countries of the world, and subsequently unique coefficients were derived. Multiplying the unique coefficients with the sum of lights provided estimates of total economic activity, which were spatially distributed to generate a spatially disaggregated 1 km2 map of total economic activity.
