Impact of spatial land use change on green space and water yield in Batu Pahat, Johor

Globally, the accelerating urbanization led by the industrialization and population growth can cause the environment degradation. The urban expansion particularly to the conversion of land activities affects the ecosystem services critically. Water yield acts as one of the important elements in the...

The research objectives are to i) quantify the spatial land use change in Batu Pahat, Johor in year 1999, 2010 and 2018, ii) to identify the water yield of Batu Pahat in years 1999, 2010 and 2018, and iii) to determine the relationship between water yield, vegetation and urban expansion.

The results for water yield from the InVEST model shows that the vegetation has the higher water yield than built-up.
