| Summary: | Land use changes in urbanization, industrialization, and agricultural processes will continue to have negative
impacts on water quality at all scales. The impact of land use changes on water quality is generally studied by
analyzing the relationships between land use and water quality indicators. Therefore, the purpose of this research
was to review and analyze the main relationships between land use and water quality, as well as to visualize the
major sources and processes of water quality pollution in Malaysia. To achieve our goal, we evaluated the
significance of both land use and water quality attributes used in the past studies and correlated them to
understand their relationship from another angle of view. The results revealed that 87% of the reviewed studies
indicated urban land use as a major source of water pollution, while 82% indicated agricultural land use, 77%
indicated forest land use, and 44% indicated other land uses. However, the results of correlation analysis showed
that agricultural and forest-related activities more affected water quality through their significant positive correlation
with physical and chemical indicators of water quality, while urban development activities had a greater impact on
water quality through altering hydrological processes such as runoff and erosion. These findings would provide
decision-makers with useful information for managing water pollution processes rather than sources only. |
