Challenges and Opportunities in Remote Sensing for Soil Salinization Mapping and Monitoring: A Review

Meeting current needs without compromising future generations’ ability to meet theirs is the only path toward achieving environmental sustainability. As most valuable natural resource, soil faces global, regional, and local challenges, from quality degradation mass losses brought on by salinization. These issues affect agricultural productivity ecological balance, undermining sustainability food security. Therefore, timely monitoring accurate mapping of salinization processes are crucial, especially in semi-arid arid regions where climate variability impacts have already reached alarming levels. Salt-affected has enormous potential thanks recent progress remote sensing. This paper comprehensively reviews sensing assess The review demonstrates that large-scale salinity estimation based tools remains a significant challenge, primarily due data resolution acquisition costs. Fundamental trade-offs constrain practical applications between resolution, spatial temporal coverage, costs, high accuracy expectations. article provides an overview research work related using By synthesizing highlighting areas further investigation needed, this helps steer efforts, insight for decision-making resource management, promotes interdisciplinary collaboration.
