A new report from CIESIN and the Austrian Insitute of Technology has released an global assessment on light pollution on protected areas.
The analysis is done to reveal how light pollution affects protected areas. Hence, two new variables was created from combining the global protected area distribution data and nighttime lights data: a Protected
Area Light Pollution Index (PALI) and a Protected Area Human Impact Index (PAHI).
Results indicate that regions in Europe and Asia Minor, the Caribbean, South and East Asia as well as in
the Eastern part of the United States are most affected. Introducing aggregated data on biomes reveals that
temperate broadleaf and mixed forests suffer the biggest impact both in terms of general light pollution as
well as lighting in protected areas. The presented risk assessment underscores the need for accurate and
consistent spatial data on a global scale and can help to indicate which protected areas globally and
nationally are at greatest risk of human activities. It is also an important step towards public communication
and raising general awareness on the topic of light pollution.
