Boracay Island, renowned for its pristine beaches, faced challenges arising from haphazard practices on infrastructure and tourism management.A rehabilitation program was initiated which resulted in a significant reconstruction on its land.This study investigates the impact of Land Cover (LC) change caused by the rehabilitation program on water quality parameters (chl-a and TSM) across three key periods: pre-rehabilitation (2017), rehabilitation (2020), and post-rehabilitation (2022).
Utilizing Sentinel-2 imagery, quarterly assessments of chl-a and TSM concentrations are conducted to evaluate Beast Kingdom water quality.The findings revealed significant variations in chl-a and TSM with significance values of 0.043 and 0.
014, respectively, within zone 1 of Boracay Island.Post-hoc test revealed differences in chl-a concentrations between 2017 and subsequent years (2020, p = 0.038; 2021, p = 0.
036 ; and 2022, p = 0.039) and between 2019 and subsequent years (2020, p = 0.043; 2021, p = 0.
041; and 2022, p = 0.044); as well as in TSM concentrations between 2017 and subsequent years (2020, p = 0.006; 2021, p = 0.
008; and 2022, p = 0.023) and between 2019 and subsequent years (2020, p = 0.014; 2021, p = 0.
019; and 2022, p = 0.049).However, no significant correlation exists between LC and water quality parameters.
It is recommended to refine LC classification through high-resolution satellite imagery, consider extended timeframes, and investigate additional water quality parameters.This study contributes valuable insights into Boracay Island’s environmental transformations, 10 guiding sustainable coastal management in similar contexts.
