Spatiotemporal environmental changes lead to disturbances in wild plant habitats, particularly regions characterized by changeable land use and cover. The present study aims characterize habitats the River Nile region of Dakahlia Governorate using a multidisciplinary approach, incorporating remote sensing, GIS sampling analyses. Twenty-four stands representing were geographically identified, sa...

To increase agricultural productivity and ensure food security, it is important to understand the reasons for variations in irrigation over time. However, researchers often avoid investigating water due data availability challenges. This study aimed assess performance of system winter wheat crops using a high-resolution satellite, Sentinel 2 A/B, combined with meteorological Google Earth Engine...

Abstract. The urban heat island (UHI) is a common effect caused by urbanization and has been studied to evaluate the thermal condition in cities worldwide. However, most previous UHI analyses are performed major metropolitan cities. This study conducts spatiotemporal analysis of rapidly expanding low-density suburban centre determines how bio-productive land covers react extent disturbance each...

Lake Urmia is the 20th largest lake and the second largest hyper saline lake (before September 2010) in the world. It is also the largest inland body of salt water in the Middle East. Nevertheless, the lake has been in a critical situation in recent years due to decreasing surface water and increasing salinity. This study modeled the spatiotemporal changes of Lake Urmia in the period 2000–2013 ...
