1 Water Resource Management in Jakarta Based on Climate Change By: Armi Susandi, Atika Lubis, Rusmawan Suwarman, Mamad Tamamadin, Sepanie Putiamini

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 Ground Types Map rainfall Infiltration factor (K) Subsidence Map WS=CH-Ep Projection of Population Evapotranspiration I=K x WS Water Needs Water reserve= I x A (Population Area) Rainfall Projection Analysis of Water Reserve Infiltration in Jakarta Water Reserve in Jakarta Adaptation option to water resource management in Jakarta Geological map Climatolog y Data Land Use Map Populatio n Data Flow Chart of The Research

6 PROJECTION OF MEAN RAINFALL IN WET MONTHS OVER JAKARTA

7 Projection of Rainfall in Jakarta (Wet Months 2010) 600 mm (Susandi et. al, 2009)

8 Projection of Rainfall in Jakarta (Wet Months 2015) 600 mm (Susandi et. al, 2009)

9 Projection of Rainfall in Jakarta (Wet Months 2020) 600 mm (Susandi et. al, 2009)

10 Projection of Rainfall in Jakarta (Wet Months 2025) 600 mm (Susandi et. al, 2009)

11 Projection of Rainfall in Jakarta (Wet Months 2030) 600 mm (Susandi et. al, 2009)

12 Projection of Rainfall in Jakarta (Wet Months 2035) 600 mm (Susandi et. al, 2009)

25 Projection of Land Use and Water Rain Absorbent Land in Jakarta Landuse Area (km 2 ) Swamp Open land Farm Public facility Vegetation Shelter Absorbent Land

26 Decrease of Absorbent Land in Jakarta

27 Subsidence in (Hasanuddin, 2008)

28 Subsidence in (Hasanuddin, 2008)

29 Projection of water reserve in Jakarta contributed by Rainfall Infiltration

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

33 Index of Climate Change Vulnerability 2015 (Susandi et. al, 2009) 1 From South Area Development: 1.Water Resource 2.Water Collector

34 Index of Climate Change Vulnerability 1 (Susandi et. al, 2009) 2020 From South Area Development: 1.Water Resource 2.Water Collector 3.Polder

35 Index of Climate Change Vulnerability 1 (Susandi et. al, 2009) 2025 From South Area Development: 1.Water Resource 2.Water Collector 3.Polder 4.Networking Pipes

36 Index of Climate Change Vulnerability 1 (Susandi et. al, 2009) 2030 From South Area Development: 1.Water Resource 2.Water Collector 3.Polder 4.Networking Pipes 5.More Pipes & Polder

37 Index of Climate Change Vulnerability 1 (Susandi et. al, 2009) 2035 From South Area Development: 1.Water Resource 2.Water Collector 3.Polder 4.Networking Pipes 5.More Pipes & Polder
