Innovative land use planning for natural hazard risk reduction: A consequence-driven approach from New Zealand

The qualitative risk assessment model of riskote decision support system

“…With the implementation of RiskOTe it is possible to state that a decision support system has been conceptually defined based on a qualitative risk assessment model allowing the elaboration of scenarios that can support the decision on the transformation of land use. The scenarios in this article reinforce the framework described by Saunders and Kilvington (2016) showing that is possible to develop risk-based land use planning, supporting the inclusion of natural hazard risk assessments in land use decisions. The inclusion of natural hazard risk assessments in land use decisionsbased onRiskOTe, allowmunicipalities to be aware of and explore vulnerability challenges when making policy and planning decisions.…”

“…The matrix is classified in fourcolors that can be used as descriptors for land use control (Table 3). Adapted from Saunders (2012) The land use control levels increase with the level of risk, supporting possible decision-making (Table 4).…”

Land Use Planning for Natural Hazards

“…In many cases, land use planning for addressing natural hazards is based on the probability of an event occurring, with little or no consideration of the consequences associated with natural hazard events [18]. For instance, floodplains are fertile, level, easy to excavate, near water and, thus, are favorable sites for urban development.…”

"Property Purgatory"

“…Risk is the likelihood of 'x' consequence for an asset over time (Grace, Kilvington and France-Hudson, 2019;Saunders and Kilvington, 2016). However, in exposed locations, climate change impacts such as coastal erosion and increasingly high tides are beyond 'risk' in this sense, as their likelihood is certain.…”
