1. General information
2. Objectives of the intervention
Goals of the intervention
1. Contribute to climate change mitigation by storing "blue carbon" through mangrove plantations.
2. To provide more habitats for biodiversity and preserve the existing species variety including the native ones.
3. To provide a place for people to get out for some respite and recreation amidst the COVID-19 pandemic.
4. To create a new wildlife look-out and educational signage so that visitors of all ages can get up close to nature. [1, 2, 4]

Implementation activities
The Kingfisher lake and the Lotus pond, two bodies of water, which were previously separated, were connected by two streams running under a footpath. Along with having water cascading into a rock pool, the streams were created to help increase the level of oxygen in the water. Water is pumped from Kingfisher Lake and flows into the Lotus Pond as a waterfall. The water then flows back into the lake through the two streams via gravity as the pond is located higher than the lake. Additionally, more than 200 mangrove plants, some from critically endangered native species, were planted in the Lotus Pond. Other new implementation activities at the wetlands included a wildlife lookout shelter and a Kingfisher Trail. [3]

5. Innovation
Type of innovation
Please specify technological innovation
The two bodies of water, which were previously separated, were connected by two streams running under a footpath. By introducing this flow of water, the aeration of the two water bodies has been increased, which in turn helps to improve the quality of the water. In addition, the streams allow smaller species of wildlife, which might face predators in the larger surrounding bodies of water, to find refuge in the Lotus Pond. [3, 4]

Replicability/Transferability
Please specify Replicability/Transferability
The results have shown that the carbon content of the soil in the Lotus Pond is comparable with that found in natural wetland habitats, which are very efficient in storing carbon. By using the Kingfisher Wetlands as a living laboratory and transferring the technology to other nature-based interventions in any urban landscape, it could be further explored how best to maximise the potential of constructed wetlands for long-term carbon storage.
