Strengthen Jakarta- if that is possible-
It will support us, help us reach our dreams.

9. Urban Heat Island Effect
“This has resulted in increased consumption of energy for air-conditioning to cool
buildings, which in turn contributes to higher ambient temperature in the city.”

12. Deforestation
“Due to the high rate of deforestation and land use change across the archipelago, Indonesia
comes in as the country with third-highest emission of greenhouse gases globally.”
Mangroves help to slow the current and prevent floods

16. Adaptation
“This is powerful, locally organized example of how residents in communities are connecting through their
own means to more sophisticated and established water management technology at the region level.”
Kampung Melayu
• One of largest and oldest villages in Jakarta
• A mix of formal and informal settlements
• Close relationship in the community
• Teneous housing construction
Flood early warning system
• Mobile phone SMS messages
• Broadcasting system
• Leave bottom level empty when flooding.

19. Conclusion
Steps Towards Resilience
The key for Jakarta going forward is to link its climate change adaption actions to the existing and new spatial plans.
