The 6 Cis river basin territory faces daunting challenges triggered by rapid urbanization with potential negative impacts on the water resources sector if not properly addressed. The main objective of subcomponent B2 of the ICWRMIP within component B is to provide the IWRM planning process in subcomponent B1 and the components C and D (TA 7189-INO) with internally consistent quantitative spatial planning outputs based on the Java Spatial Model (JSM). Projections for population growth in the whole of Java are straight forward, but projections of growth in each village and related land use are more complicated. This model is used to provide spatial projections of population and associated land use changes for all villages on Java, based on population projection for Java and economic growth projection by province.
