{"abstract":"This quantitative study examined the socio-economic impact of the Marine Protected Area (MPA) in Cortes, Surigao del Sur, Philippines. The research aimed to assess how MPAs influence income, education, occupation, and marine resource availability. Using a descriptive-correlational design, structured surveys were conducted among 516 respondents, including fishermen, MPA managers, government officials, and community members, selected through stratified random sampling. Data were collected using structured questionnaires and analyzed using descriptive statistics and multiple regression analysis. Results indicated moderate positive impacts of the MPA on income generation, educational awareness, employment diversification, and marine resource conservation. Significant relationships were found between demographic characteristics such as age, gender, educational attainment, income, occupation, and the perceived socio-economic benefits of the MPA. The study concludes that MPAs can enhance both ecological and socio-economic outcomes when supported by inclusive community programs and alternative livelihood initiatives.","abstract_source":"original","authors":["Mercedette Dumagan","Floresito Calub"],"date":"2025-05-18","doi":"10.70838/pemj.370906","id":5233,"issue":9,"journal":{"issn":"2822-4353","name":"Psychology and Education: A Multidisciplinary Journal"},"pdf_sha256":"6160e6719b3f9b1b5fea10fc1255da953aa7ca6e2537fc7115f7d54c0f0c35a1","schema":"scimatic-article/1","title":"Understanding the Socio-Economic Influence of Marine Protected Areas in Coastal Communities","volume":37}
