Water is essential in our daily life for life purposes and other activities. Significant water quality degradation due to natural factors and human activities can harm human health and ecosystems. Therefore, water quality monitoring is always necessary for public health and a good ecosystem. This study focuses on assessing river water quality in Terengganu involving several parameters and the location of water monitoring stations along the Terengganu River, which is linked to the second-largest dam in Malaysia. This study uses multivariate analysis such as Principal Component Analysis (PCA) and Agglomerative Hierarchical Clustering (AHC) to assess water quality in the Terengganu River. PCA investigates the origin of each parameter that contributes to river pollution. Before AHC, WQI categorized monitoring stations based on different river pollution zones. The AHC method groups all water monitoring stations based on the level of river pollution zones. Then, this study was continued with the Fuzzy Decision-Making Experiment and Evaluation Laboratory (FDEMATEL) to determine the relationship between river pollution factors. The PCA results yielded five significant factors that accounted for 55.33% of the total variance. AHC classifies three clustered areas: low, medium, and high pollution. Criterion (agricultural and irrigation run-off) is the main causal relationship from FDEMATEL. The results of this study help reveal important information about river water quality in Terengganu to control pollution sources, thus helping to maintain the health of the local population and ecosystem.

“…Forests constitute a crucial component of ecosystems, playing a vital role in maintaining Earth's ecological balance [9]. They contribute to air purification [10,11], water resource protection [12], soil conservation [13], and prevention of natural disasters [14] while serving as habitats for numerous flora and fauna. Forests are crucial in climate regulation, making them pivotal in mitigating global warming [15].…”

Forest park tourism ecological security is the cornerstone of ensuring ecological tourism safety. Delineating the ecological carrying capacity within forest parks is crucial for enhancing the security of forest tourism resources. This study utilizes statistical data from China’s forest parks spanning 2004 to 2019, employing methodologies to comprehensively depict the spatiotemporal dynamic characteristics of forest park tourism ecology in China. Subsequently, this research forecasts the prospective trajectory of forest park tourism ecology in China from 2020 to 2029. The research findings reveal that China’s forest park tourism ecological footprint exhibits oscillating characteristics, while the overall touristic ecological carrying capacity shows a sustained upward trend. However, a significant portion of regions experience deficits in tourism ecology. Notably, the coldspot regions with ecological security features demonstrate relative stability, while the hotspot areas gradually transition from inland to eastern coastal regions. Spatially and temporally, the disparities in touristic ecological profit and deficit depict a “U”-shaped distribution, more pronounced along the east–west axis than the north–south orientation. The migratory shift in the touristic ecological surplus and deficit center gravitates towards the southwest, demonstrating a fluctuating trend characterized by varying migration speeds. The discernible difference between the east and west concerning touristic ecological profit and deficit amplifies the likelihood of imbalance, surpassing disparities between the north and south. Projections suggest a deepening forest park tourism ecological deficit in China from 2020 to 2029, particularly accentuating the unsustainable development of forest park resources in economically developed regions. Through this study, a more comprehensive understanding of the current status and changing trends in the ecological carrying capacity of forest park tourism can be obtained. This research provides theoretical and practical support to promote sustainable tourism development and establishes a solid foundation for the ecological security of future forest park tourism.
