摘要

Working with South Africa's largest short-term insurer, Santam, we investigated how communities should manage the increased risks associated with climate change. The global insurance industry has focused on refining the quantification, differentiation and pricing of the risk exposure of insured assets. Our findings call into question a sole reliance on this strategy (J. Nel etal. CSIR/NRE/ ECOS/2011/0063/B; CSIR, 2011). More than 80% of weather-related insurance claims in South Africa's southern Cape region were incurred in the past five years. Worse, climate models indicate that fire, flood and sea-storm risks in the area are set to increase significantly in the next 40 years. We found that a l-in-75-year flood risk, as determined by rainfall data, could change to 1 in 45 years as a result of observed changes in land use. Risk is a dynamic and emergent property of nonlinear relationships between different risk drivers. In such fast-changing complex systems, static spatial differentiation of risk becomes less relevant.

Nel等,CSIR / NRE / ECOS / 2011/0063 / B; CSIR,2011年)。在过去的五年中,南非南部开普地区有超过80%的与天气相关的保险索赔。更糟糕的是,气候模型表明该地区的火灾,洪水和海暴风险在未来40年中将大大增加。我们发现,根据观测到的土地利用变化,降雨数据确定的每75年发生一次洪水的风险可能在45年内变为1年。风险是不同风险动因之间的非线性关系的动态和新兴属性。在这种瞬息万变的复杂系统中,风险的静态空间差异变得不那么重要。
