Earthzine.org is soliciting articles of 800-3,000 words for its 3rd Quarter Theme Issue on Urban Monitoring. About half of the planet’s 6.6 billion people now live in urban areas, which occupy less than 3% of the land area. By the year 2025, the global population is expected to reach 8 billion, of which 5 billion are expected to reside in urban areas. Now is an opportune time to examine trends and developments in urban monitoring.
