Introduction: Remote sensing technology has significantly expanded in the last two decades for monitoring health of coastal waters Objective: This paper aims to explore efficacy remote technologies mapping, analyzing, and visualizing macroinvertebrate communities ecosystems. Theoretical Framework: study, is based on Sustainable Development Goals (SDGs) concept, direct further research offer suggestions better ecological monitoring. Method: study uses a systematic literature review (SLR) examine role (RST) ecosystems assessing water quality. It draws data from multiple databases, including Google Scholar, Springer, PubMed, others, analyze efficiency RST communities. The selected papers were qualitatively analyzed using NVivo software. Results Discussion: highlights transformative impact monitoring, demonstrating improved accuracy (85% vs. 70% with traditional methods), high-resolution imaging habitat analysis, robust predictive modeling (r² > 0.75) biodiversity mapping. These findings advance insights, enhance support conservation management initiatives. Research Implications: emphasizes accuracy, hotspots, aiding conservation, resource allocation, sustainable ecosystem while addressing challenges like environmental variability, accessibility, costs. Originality/Value: improving modeling. advances supports efforts, addresses variability accessibility inspire future innovations.
