introduction the increasing use of satellite remote sensing data for civilian use has proved to be the most cost-effective means of mapping and monitoring for environmental changes. satellite remote sensing has played a pivotal role in finding forest cover, vegetation type and land use changes in urban areas. one of the most complete of these methods is classification. the conventional per-pixe...

Urban trees and forests are one of the main tools available in cities to face current future environmental challenges ultimately promote well-being. More than half world’s population lives nowadays. This rural exodus resulted from a pursuit better life quality. However, urban increase led new levels complexity. Such complexity calls for multifunctional solutions such as Nature-based Solutions (...

Elevated summertime temperatures in urban ‘heat islands’ increase cooling-energy use and accelerate the formation of urban smog. Except in the city’s core areas, summer heat islands are created mainly by the lack of vegetation and by the high solar radiation absorptance by urban surfaces. Analysis of temperature trends for the last 100 years in several large U.S. cities indicate that, since | 1...
