| dc.description.abstract | The decline of ecosystem services has emerged as a critical issue in the 21st century because of different antropogenic factors.This study investigates the spatiotemporal dynamics of ecosystem services in the Geray swamp area, utilizing geospatial and socioeconomic data. By identifying various ecosystem services and analyzing the drivers of change, the research aims to fill knowledge gaps and enhance understanding of how human activities impact these vital ecosystems. To achieve the research objective, an explanatory sequential mixed research design and systematic random sampling technique was applied. The research result shows that land use and land cover changes reveal significant transformations, including a reduction in swamp area,open water and vegetation areas, alongside an increase in built-up and cultivated lands. Specifically, the swamp area decreased by 53.69%, while built-up areas increase by 501.92%. The spatiotemporal dynamics of ecosystem services using the lense of indices such as the NDVI, WVI, and MNDWI,the results indicate a significant decline in vegetation health, swamp vegetation cover, and open water extent. The result of ecosystem service valuation reveals significant declines across all service categories. Total ESV decreased from $3.853 million in to $2.783 million, marking a total loss of $1.068 million.The result of ecosystem service gains and losses highlighting the significant impact of land use changes.Additionally, the Coefficient of Sensitivity (CS) analysis indicates that swamp, open water, and vegetation are highly responsive to environmental changes, with CS values close to 1. The result shows also socio-economic factors influencing ecosystem service changes, utilizing both quantitative and qualitative methods. A survey of respondents revealed strong perceptions in multiple linear regression model regarding the impacts of land use changes, hydrological alterations, over-exploitation, socio-economic influences and pollution on ecosystem services. Descriptive statistics indicated high agreement on the detrimental effects of these factors with mean scores reflecting significant concerns. The correlation and regression analyses confirmed negative relationships between ecosystem service and the identified factors, particularly socio-economic factors, which showed the strongest correlation. Generally,the Geray swamp area has undergone significant ecological changes, marked by a decline in natural habitats and a loss of ecosystem service, underscoring the need for sustainable management and community engagement. | en_US |
