Jakarta: Climate change adaptation

Climate change adaptation

Mangrove protection is considered as one of the best ways to protect the coastal area. In the city, technical flood measures continue to be taken to improve drainage and prevent floods. These include improved maintenance, cleaning and dredging of waterways; improvement and maintenance of technical infrastructure; and improving the discharge capacity of rivers and retention capacity of the soil. However, there has also been more investment in non-structural measures such as awareness raising programs, law enforcement and early warning and emergency assistance systems, and upper watershed planning and management.

Greater Jakarta has prepared a policy for disaster management, including an implementation strategy. It is also conducting regular disaster drills, and focusing on early intervention to reduce the loss of life and economic damage. Another important development is the 2008 presidential decree which aims to regulate land use for various purposes across Jakarta and its upstream areas. The decree sets out ambitious targets for ensuring the integrity of spatial planning, and sustainability of the environmental carrying capacity (water supply, food protection, local economic development).

JCDS (Jakarta Coastal Defence Strategy)

The Jakarta Coastal Defence Strategy is a strategy that is being developed to cope with flooding from the sea. The chance and effects of flooding from the sea in Jakarta is increasing because of the rising sea level and soil subsidence in Northern Jakarta.

Jakarta Flood Management

To deal with flooding from the rivers and the rain Jakarta is working on a Flood Management plan. In this plan flood hazard maps are being developed and shelters and FEWS (flood early warning systems) are being developed.

Flood Hazard Mapping

With the design of flood maps the reason and impacts of flooding can be understood better. The maps which are being designed show the depth of an inundated area and the likelihood of occurrence.

Dealing with green house gas emissions

To deal with green house gasses and pollution in the city the city of Jakarta is working on a reduction plan. With this plan the city government sets itself a goal of reducing GHG emissions by 30% in 2030. Part of this plan is improving the public transport (buses, bajaj’s) and make them able to drive on gas.

Heat and heat waves

Jakarta as many other cities has to deal with the urban heat island effect. To cope with this problem Jakarta has plans to increase the amount of green (parks and trees) in the city, from 9,8% to 30% in 2013.

City to Build 1,949 Absorption Wells

Even though it is just a simple technology, the construction of absorption wells are deemed to be quite effective in handling flood. Out of the total 1,949 absorption wells that Jakarta Provincial Government is planning to build, 70 percent of them have been realized already. To socialize the use of the absorption well, The Jakarta Government will also make a regulation to obligate residential area and office buildings to build one. "We are also in the process to draft a regulation to obligate office buildings to make absorption wells," said Basuki T Purnama, Vice Jakarta Governor, as a spokesperson in a workshop Jakarta Flood Prevention Using Groundwater Technology at TMII. "We must resolve flood in a comprehensive way, from upriver to downriver. One of them is by solving the problem upriver, by supervising surrounding cities such as Bogor," he ended.
