The Chulalongkorn University (CU) Centenary Park was created to provide a green space for the city and celebrate Chulalongkorn University’s 100th anniversary. Located in the centre of shopping and commerce, the park is designed as a multi-functional “urban forest”, which serves as an oasis for the residents and visitors of Bangkok, who can spend quality leisure time in a lush and pleasant environment. The park includes constructed wetlands with rain gardens, retention ponds, an underground water drainage system and green roof areas. Opened in 2017, Chulalongkorn Centenary Park is the first critical piece of green infrastructure in Bangkok to mitigate detrimental ecological issues and disaster risk reduction. Unlike other public parks around the city, this one is the first in Thailand to demonstrate how a park can help reduce urban flood risks and help the city confront climate change, all while offering city dwellers a place to reconnect with nature. Designed with various ecological design components, the park reminds the city of ways to live with water rather than fear it. [1, 2, 4]

Creation of new green areas, Creation of semi-natural blue areas

Project objectives

1. To provide a green space for the city and celebrate Chulalongkorn University’s 100th anniversary. 2. To help reduce urban flood risks and help the city confronts climate change. 3. To offer city dwellers a place to reconnect with nature. [3]

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. [2, 4}

Climate-focused activities

Climate change adaptation:

  • Implement solutions to capture/store water to increase its availability and prevent shortages from droughts
  • Increase or improve urban vegetation cover to help reduce outdoor temperature
  • Create or improve outdoor spaces to help people escape from urban heat
  • Implement green walls or roofs to lower indoor temperature and provide insulation
  • Implement sustainable urban drainage infrastructure (e.g. to make space for water)
  • Increase the use of climate-resilient plant species (resistant to drought, fire, and pests)
