Dumping of solid waste and unstable coastal water quality has become a rising issue in the
Philippines coastal zones. Thus, this study was conducted to investigate two coastal municipalities’
(Opol and Jasaan) perception towards coastal waters (CW) and solid waste management (SWM)
along Macajalar bay, Philippines. Sociodemographic indicators of the 180 residents and how
this influenced their level of knowledge-awareness-practices (KAP) towards CW and SWM
were determined using modified survey questionnaire. Purposive sampling was employed to
communities residing adjacent to coastal waters. Both quantitative (One-Way ANOVA and
T-test for unequal variances at α-0.05) and qualitative analyses were utilized to extrapolate
conclusions. Present findings revealed varying sociodemographic indicators influencing
KAP. Opol coastal residents level of knowledge and practices were influenced by gender
(K:p-0.0314; P:p- 0.0155) and age (p- 0.0404), whereas level of awareness was influenced by age
(p- 0.0160), length of residency (p- 0.0029), and educational attainment (p-0.0089). Distinctively,
Jasaan coastal residents’ gender influenced the level of knowledge (p- 0.0223) and practices
(p- 0.0172), whereas awareness was influenced by educational attainment ( p - 0.0383). Overall,
sociodemographic response revealed higher level of knowledge and awareness towards
preservation of CW. However, low levels of practices in both municipalities towards SWM
were determined as evidenced by anthropogenic inputs to coastal water (dumping of solid
waste, animal waste and domestic wastewater). In return this exerts pressure to Macajalar Bay.
Present study can support policy enforcement in identifying opportunities for building positive
connections of the social and biophysicochemical aspects in the bay.
