Call for Papers – Urban Monitoring

EarthzineEarth Observation, Ecosystems Theme, Original, Themed Articles, Urban Monitoring Theme

Earthzine.org is soliciting articles of 800-3,000 words for its 3rd Quarter Theme Issue on Urban Monitoring. About half of the planet‰Ûªs 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.

Cropped image of a mixed forest in PortugalIn Portugal, the fire season of 2003 was the worst on record. Satellite imagery was used to study the post-fire vegetation response. The results contribute to our understanding of the impact of management strategies and can ultimately improve allocation of firefighting resources.

Normalized Digitized Vegetation Index image for portion of Tyrrell County showing green color as least vegetated; grey as greatest, red colors indicate intermediate levels of chlorophyll and Gold-colored outlines show NCDCM locations of wetlands.This article focuses on a NASA Applied Sciences National DEVELOP assistance to the North Carolina Division of Coastal Management (NCDCM) with the assessment of coastline changes and habitat loss in coastal wetlands utilizing satellite remote sensing. The Hyde, Tyrrell, and Dare counties in eastern North Carolina occupy the coastlines of the Albemarle and Pamlico Sound estuaries. The Pamlico Sound is the largest estuarine lagoon along the East coast of the United States.

Credit: NASAUsing the latest technologies to take highly accurate measurements of the Earth‰Ûªs ice sheets collected on expeditions to Greenland and Antarctica, scientists with NASA‰Ûªs Operation Ice Bridge are currently working to improve the models polar scientists around the world rely on for predictions about the future of sea level rise. This article shows how these models will provide the science to enable establishment of realistic and effective climate change policies that will not only help to lessen the effect humans are having on the climate, but also prepare us for the changes that are already coming.

Fig. 1: Distribution of GBIF species distribution data (graphics: GBIF)Natural history museums store and conserve physical specimens of animals and plants for biodiversity research. The amount of knowledge about species gathered in natural history museums (worldwide about 2 to 3 billion specimens) including information about geographical and timely occurrence is now in an early stage of being digitized for merging and distributing this information.
