Bandung City experiences flooding due to its sunken geography and environmental factors. Environmental degradation is also a factor of flood risk in Bandung City. The NbS approach offers a sustainable solution by utilizing natural ecosystems for mitigation efforts in reducing flood risk, in contrast to conventional infrastructure which is often less effective. However, in the context of Bandung City, the application of NbS must adapt to local conditions as it has its own concerns. This research adopts SWOT (Strengths, Weaknesses, Opportunities, Threats) and analytical hierarchy process (AHP) analysis methods to prioritize strategies for NbS interventions that are most suitable for implementation in Bandung City. Several NbS interventions were considered in the context of Bandung City conditions based on literature review and related studies. The SWOT analysis identified the strengths and opportunities of NbS implementation, possible challenges and shortcomings such as land constraints. After that, the results of the AHP analysis will result in the prioritization of suitable alternative strategies. The opportunity factor, which has the largest weight, plays an important role in the implementation of Nature-based Solutions (NbS). Several other factors of NbS implementation in Bandung City need to be considered or improved. Retention ponds are prioritized as the most suitable NbS strategy to reduce flood risk in Bandung City. This research also emphasizes the importance of NbS that can adapt to local conditions. In addition, this research highlights the need to pay attention to and improve local conditions in order for the implementation of NbS to work well.
