<![CDATA[Tourism has great potential to drive economic growth and act as a catalyst for the development of other sectors, and one promising destination in Banjarbaru, South Kalimantan, is Danau Seran, a notable example of transformation from a former mining site operated by PT Galuh Cempaka into a nature-based tourist attraction offering activities such as boating, fishing, and enjoying scenic views. This study aims to formulate a sustainable water resource management strategy to support ecotourism development at Lake Seran, Banjarbaru, using a typology analysis of strategic variables through the MICMAC method. Water resource management in this area is challenging because Lake Seran was formed from a former mining area. The approach used in this study is a prospective structural analysis with in-depth interviews and MICMAC software input to analyze the relationship between variables that influence water management and ecotourism development. The results show that variables such as water quality, land status, and waste management are the main priorities in current management, while tourism policy and product development will be the focus in the future. These findings provide direction for policymakers to design management strategies that are more responsive to changing priorities and evolving dynamics. In conclusion, managing Lake Seran as a sustainable ecotourism destination requires special attention to interacting variables, with a focus on nature conservation and local community empowerment.]]>
