Quantitative targets
To create 1 detention pond, 1 retention pond, 1 large green roof, 1 rainwater reserver and 4 wetlands. [4]
Monitoring indicators defined
Amount of water retained, number of beneficiaries, number of survived plant and tree species. [3]
Sustainability challenge(s) addressed
Climate change adaptation: What were the goals of the NBS?
Climate change adaptation: What activities are implemented to realize the conservation goals and targets?
Implementation activities
The implementation activities included the creation of constructed wetlands, with a rain garden, retention pond and an underground water drainage system. The park was designed to sit on a 3-degree gradual incline. The university building was equipped with a green roof to provide the city's much-needed green space. The green roof was designed to store water during the rainy season and then further use it for irrigation in the dry season. Native water plants were planted near the wetlands, which helps in filtering the water. Some water bikes were stationed near the water filtration pond. The visitors could use these to aerate the water in the pond and facilitate the filtration system. Further, an interactive virtual museum featuring historical and socially engaging topics were built.

5. Innovation
Type of innovation
Please specify technological innovation
Chulalongkorn Centenary Park is designed to face future uncertainties of climate change. The design concept inclines the entire park to create a container for water: the raised green roof directs runoff water through sloped rain gardens, filtered in the constructed wetland, and then to the retention pond. Extending the park design into the neighbourhood, a major adjacent roadway was reduced from four to two lanes in favour of widened pedestrian walkways and new bike lanes. The walkways connect directly to paths in the park, creating a seamless pedestrian experience. Linear rain gardens, with a multitude of native plants, line the road to absorb water. [3, 4, 7, 8]
Novelty level of the innovation
Please specify novelty level of the innovation
The innovation was very new in the city. For the first time in the last 30 years, an area in the heart of the city of Bangkok has been turned into a lush green area. The technology used in creating the rain garden, water retention ponds and constructed wetlands are also very novel to the city. [ 3, 7, 8]
Replicability/Transferability
Please specify Replicability/Transferability
The project results have shown that innovation could be successfully replicated without much adaptation to other parts of the city and beyond. [2, 3, 5]
