Despite increasing utilization and accuracy of models to predict the future climate and hydrology at higher resolutions, urban areas are still underrepresented. A method to determining future distribution of urban parameters in accordance with the global climate and socio-ecoonomic pathways of the future is proposed. An urban growth model was used to project the expansion of urban areas in 2050 of Jakarta. From shared socio-economic pathways (SSP), total population in the future was acquired. Using historical population distribution data, spatial distribution of population was projected until the year 2050. From empirical relationships acquired from population with nighttime lights adjustment, actual urban parameters, and GDP, futuristic urban parameters were calculated. Finally, the calculated future distribution of urban parameters was used in downscaling the future climate of Jakarta using the pseudo-global warming method.
