Small islands face an uphill battle for sustainable development, further exacerbated by natural hazards and excessive urbanization. The population of Ternate Island has increased more than fivefold in the past fifty years, coinciding with economic growth and fewer destructive natural disasters in recent years. This study undertakes a landscape analysis, scenario planning, natural hazard mapping, and resilience planning to provide practical recommendations for policymakers. A 500-year tsunami risk presents a heightened threat should a volcanic eruption occur simultaneously on the tiny island, while land-use management and zoning need to be redrawn at the micro level and enforced to prevent uncontrollable sprawl. Recent floodings and limited clean water access for residents magnify the environmental hazard risk. This study proposes a sustainable landscape planning with a focus on waste and water management. The recommendations are practical and feasible to be adopted by transformative leaders on Ternate Island.
