Jakarta City in Indonesia deals with inundations during heavy rain periods (1,2). To overcome such flooding issues, the Central Jakarta City Government, through the Parks and Forests Sub-Department, planned and implemented four bioswales and one rain garden at five locations in Central Jakarta City (1,2,3,4). This project was aimed at saving groundwater through stormwater management and minimizing puddles around the site locations (1,4). The Head of Central Jakarta City Parks and Forests Sub-Department, Mila Ananda, conveyed this project completion in 2021 (1,2). After the successful implementation of this project, the Jakarta City Government further plans to identify similar more locations prone to inundation and implement such green infrastructure initiatives in other parts of the city (1,2,3).

Overview
Nature-based solution
- Green areas for water management
- Rain gardens
- Swales and filter strips
- Grey infrastructure featuring greens
- Alley or street trees and other street vegetation
Key challenges
- Climate action for adaptation, resilience and mitigation (SDG 13)
- Climate change adaptation
- Green space, habitats and biodiversity (SDG 15)
- Green space creation and/or management
- Water management (SDG 6)
- Flood protection
- Stormwater and rainfall management and storage
- Health and well-being (SDG 3)
- Creation of opportunities for recreation
Focus
Creation of new green areas, Creation of semi-natural blue areas
Project objectives
- To reduce the potential for inundation during heavy rains and overcome flood issues by application of green infrastructure strategies
- To use green infrastructure strategies like rain gardens and bioswales for stormwater management
- To develop rain gardens and bioswales in the city as a source to save groundwater
- To maximize the infiltration function of green open spaces
- To beautify the city layout by increasing green spaces, while using native species for plantation
- To create opportunities for relaxation/recreation for users (1,2,3,4).
Implementation activities
- Construction of bioswales and rain garden in green belt areas and green open spaces such as:
The four bioswales that have been implemented are RTH Manggala on Jalan Penjompongan Raya, the green line for Jalan Tambak, the green line for Industrial Road, and the green line for Simpang Lima Senen and one rain garden that has been completed is at Tamai Boi Trans Park - Jalan Letjen Suprapto (1,2,3,4). The total area of the NBS initiative was 328.03 meters such as: The Manggala RTH bioswale (51.22 m); Tambak Road bioswale (43.5 m); Industrial Road bioswale (19.12 m); Simpang Lima Senen bioswale (16.19 m); and one rain garden at existing Tamai Boi Trans Park - Jalan Letjen Suprapto (198 m) (1).
- Increase in green spaces through the use of native plantations such as papyrus, centipede ferns, red reeds, green reeds, irish, pacing pin, kadaka, latana, fountain daffodils, aralia, pretty pink, yang liu, water bamboo and lollipops (1).
