Similarly, a civil war in Cote d\u2019Ivoire from 2002 to 2004 severely darkened the country, with lights only returning in recent years. As well, increased lighting in Iraq in 1999 corresponded to the UN lifting import restrictions at the time, while external investment in Afghanistan led to increases in satellite-observed lighting starting in 2002.<\/p>\n<p>Perhaps not surprisingly, countries undergoing rapid growth, such as China, had a high correlation between lighting and both GDP and population. In contrast, highly developed countries, such as the U.S. and Western Europe, showed fairly stable lighting patterns that didn\u2019t shift despite increases in population and GDP.<\/p>\n<\/blockquote>\n<p>This effect is clearly visible in the contrast between China and South Korea, Japan and Taiwan from 1992 to 2010 (<strong><a href=\"http:\/\/www.wired.com\/wiredscience\/2011\/12\/light-space-change\/\">click through<\/a> <\/strong>to view a time-lapse sequence).
