There are too much examples of risks for islander's life. For our study some criteria can be arranged to meet the difficulties for sustainability: long impact, huge loss, heavy and basic damages for 3 lives of islanders (life-long effect, their physical and psychological conditions), exposure on prerequisite environmental elements for their community life (5 wares=hard ware, soft ware, human ware, spiritual ware, ecological ware), developmental conditions especially for their next generation (education, skills, job opportunities, equity, human resources for youth, stock base, QOL acquisition more than BHN) and conquest of trade-off dilemma. The taxonomy of events is also effective to know the boundary and diversities for preparatoin. Man-made disaster: war, governance mistake, illegal waste dumping, pollution, red soil by development of farmland, confinements in leper colony, specific heavy taxes, debts of the community and crime like abduction. Natural disaster on earth (volcano eruption, tsunami, great earthquake, land slide or fall, land subsidence), weather (typhoon and strong wind, tidal wave, heavy rain or flood, damage from salt, drought, and climate change and sea rise) and creature (outbreak of harmful insects, exotic animal and plants, poison, worthy exposure in natural park, heritage or Ramsar wetland, and island biodiversity).
All of these might be only sample studies, however if we can do enough, we can make island calamity list against sustainability. After some steps we can get sufficient conditions to prepare any risk and step up strategy towards island sustainability and nissological methods for risk management and governance.
