Water quality changes using GIS-based approach at seagrass meadows along the straits of Johor

Industrialization and urbanization promote socio-economy development but they unwittingly cause environmental problems. Land use change always brings about the changes of ecological components including water quality and richness of marine communities. Rapid alteration in coastal landscape, increasi...

description Industrialization and urbanization promote socio-economy development but they unwittingly cause environmental problems. Land use change always brings about the changes of ecological components including water quality and richness of marine communities.
