“…Furthermore, LULC information, particularly satellite images, had been accessible due to the many new generation Earth observation satellites deployed in space (Sekertekin et al, 2017). Brought about by different calamities that have entered the Philippines, natural factors and anthropogenic factors greatly contribute to the increased risk of affecting coastal areas, specifically the occurrence of coastal erosion and sea-level rise (Arias et al, 2015). Therefore, with increasing risk in coastal areas, the study aims to detect land use/ land cover change of the coastline of La Union over the last 30 years through the following specific objectives: to create a map showcasing changes in La Union's coastal area over 30 years, to verify results using machine learning, (i.e.…”

With the hazards piling up on a global level, especially in the coastal areas, this study aims to employ remote sensing and Geographic Information System (GIS) in assessing the Land Use/ Land Cover Change (LULCC) data of the coastal municipalities of La Union, Philippines. Through spatiotemporal maps along with computer-generated results, landscape changes were observed and assessed qualitatively (LULC) and quantitatively (accuracy assessments, change detection analysis) for analyzing LULCC. The occurrence of landscape fragmentation was observed across the five classes (water, urban, barren, vegetation, and agricultural land), particularly between urban, vegetation, and agricultural land, showing interrelationship with landscape stability and fluctuations across a three-decade period (1990-2021) with an accuracy assessment result of 60%- 94%. Significant changes across the three decades showed a decrease in vegetation, -15.32%, and an increase in the remaining four (water, urban, agricultural land, and barren) with +3.11%, +2.71%, +7.01%, and +2.48%, respectively. The result of the study highlighted the need for developing conservation measures crafted on sustainable land use policies and interventions for coastal resources management and shoreline protection.
