Document Summary
Events which occur in the tails of a probability distribution of a given variable (e. g. daily rainfall/number of days since rain) How extremes might change: shift in mean, variance & symmetry of distribution. Kills more than any other natural hazard in aus. Poses risk to all (esp. old, young, poor, unwell, disabled) Major cost and demand on health care & emergency management services. Why interest in urban heat & role of wsud (water-sensitive urban design) in heat mitigation. Urban/city environments (urban heat islands uhi) are hotter than rural (less water, more paved and impervious) - harvesting stormwater (as rainfall typically goes down drains) to make environment more natural, to increase tree/green cover (supported by irrigation/stormwater) Micro-scale backyard irrigation, roadside tree planting, green walls/roofs. Neighbourhood/city scale open water bodies (lakes), urban forestry, irrigated open green space, increased vegetation cover. Drought: an extended/unusual dry period which results in a shortage of (useful) water.
