Jakarta has a long history of flooding. In recent decades, rapid urbanisation, land use change, land subsidence, and the clogging of the city’s waterways with garbage and sediments have intensified this problem. Future climate change will further increase the chance of flooding.
Flood risk and climate adaptation
Traditional flood management in Jakarta has mainly focused on reducing the chance of flooding. However, there is a growing recognition of the need for a more integrated flood risk approach, whereby risk is the combination of both the probability of flooding and the consequences (e.g. economic damage and loss of life). Whilst climate change clearly brings new threats to Jakarta, and other delta cities, it also provides an opportunity to plan adaptation measures that reduce flood risk both today and in the future. However, there is lack of scientific knowledge and tools on the impacts of adaptation on flood risk.
Aims and objectives
The overarching objective is to contribute to the development of tools to assess, compare, and optimise options for climate adaptation Jakarta and other delta cities. The aims main aims are:
- To contribute knowledge and capacity building on flood risk, climate change, and spatial planning in Jakarta;
- To improve tools for assisting in decision-making on flood risk adaptation;
- To improve the integration of spatial planning and water management by developing new methods in flood risk assessment and socioeconomic evaluation;
- To assess the impacts of adaptation strategies in terms of costs and benefits in order to assist in identifying good solutions for risk reduction
JCAT session at 5th Asian Ministerial Conference on Disaster Risk Reduction (AMCDRR)
In October 2012, the Jakarta Climate Adaptation Tools (JCAT) team co-organised a session at the 5th Asian Ministerial Conference on Disaster Risk Reduction (AMCDRR) in Yogyakarta, Indonesia.
AMCDRR is a biennial conference organised by rotation in different Asian countries since 2005. The conference serves as a forum to exchange experiences on successful practices and innovative approaches in implementing the Hyogo Framework for Action’s five priorities for action at national and local levels.
The 5th AMCDRR conference had the theme “Strengthening Local Capacity for Disaster Risk Reduction”. JCAT contributed to this theme by co-organising a session on local risk reduction initiatives in Asia. In the session, the team presented the first results of JCAT. The presentation highlighted the need to assess both the costs and benefits, in economic and social terms, of a large range of flood risk reduction measures. Instead of only focusing on traditional infrastructural measures (such as dikes and sea-walls, which are of great importance), more attention should also be paid to options such as forestation in the upper catchment areas, early warning systems, spatial zoning, and reducing land subsidence through the improved supply of drinking water. A fruitful exchange of knowledge took place between researchers, NGOs, and policy–makers from countries including Indonesia, Vietnam, Bangladesh, and South Korea.
Consortium: IVM-VU University Amsterdam, Gadjah Mada University Yogyakarta, Wageningen University, and Bogor Agricultural University. The research will be carried out in close collaboration with LIPI (The Indonesian Institute of Sciences) and stakeholders in Jakarta. A definition workshop was held in Jakarta on 18 January 2011.
