2 OUTLINE Introduction Objective Methodology Result and Analysis
Adaptation Option Suggested References

3 Introduction Global climate change causes many areas in Indonesia to be vulnerable on its impacts. DKI Jakarta is recently and in the future in crowded population. Climate change causes pattern of rainfall and effect to frequency and intensity of rainfall in Jakarta. Subsidence of water level is happened in aquifer ground.

4 Objectives To identify projection of rainfall and other parameters regarding to the water resources in Jakarta. To estimate Jakarta’s water reserve in the future. To conceive the climate change adaptation solving the water resource management in Jakarta.

5 Flow Chart of The Research

30 Comparison between Water Need and Water Supply
Need of water per person in Jakarta is up to 175 liter/day (Kompas, 2005).

31 ADAPTATION OPTIONS SUGGESTED TO JAKARTA
Jakarta map is also embedded by index of climate change vulnerability

32 2010 From South Area Development: 1. Water Resource
Index of Climate Change Vulnerability 1 Development: 1. Water Resource (Susandi et. al, 2009)

33 2015 From South Area Development: Water Resource Water Collector
Index of Climate Change Vulnerability 1 Development: Water Resource Water Collector (Susandi et. al, 2009)

34 2020 From South Area Development: Water Resource Water Collector
Index of Climate Change Vulnerability 1 Development: Water Resource Water Collector Polder (Susandi et. al, 2009)
