The role of geospatial techniques on the evaluation of soil salinity – worldwide review
Abstract
Soil is an essential part of ecosystem acting as a sustainer, provider, regulator, and cultural asset within the context of ecosystem services. World-wide soil salinity is a serious issue with far-reaching consequences for crop production, ecosystem wellness, and land destruction. Classical literature reviews fall short of addressing the transdisciplinary character of this topic. In response, the paper uses bibliometrics analysis to supply important perspectives into the present state of soil salinity research. This study aimed to identify existing challenges and notable research gaps through an extensive review of publications spanning the past twenty-three years. The analysis, based on 1428 publications indexed in Scopus, comprehensively examines publication trends, types, influential authors, affiliated institutions. We also identify key sponsors, co-authorship and keyword networks. Key research topics encompass soil salinity, remote sensing, mapping techniques, and satellite imagery. Over time, the volume of publications in this field has consistently increased, with research articles being the predominant format. Through this analysis, three major research directions concerning soil salinity processes are identified, offering valuable insights for future investigations. The trajectory of this scientific field in the coming years should prioritize fostering collaboration among researchers and harnessing the potential of remote sensing technologies to comprehensively advance our understanding of soil salinity.
