Editing Wetland Area Loss Rate (section)

== Monitoring and Measurement ==
Monitoring of wetland area loss relies primarily on wetland inventories and land cover monitoring programs that utilize remote sensing technologies, aerial photography, and field surveys. Satellite imagery from platforms such as Landsat and Sentinel enables periodic assessment of wetland extent changes over large spatial scales. These data are complemented by ground-based observations that validate and refine remote sensing interpretations.

Institutions involved in wetland monitoring include national environmental agencies and international organizations that maintain wetland databases and conduct systematic land cover classifications. Standardized methodologies for detecting wetland boundaries and changes over time support consistent measurement of loss rates.

Within the SIGNAL system, this phenomenon is treated as a defined environmental signal whose boundaries and measurement conventions are described below.
