Abstract
Purpose
The purpose of this paper is to demonstrate a spatial model of population vulnerability (VI) capable of identifying areas of high emergency service demand (ESD) during extreme heat events (EHE).
Design/methodology/approach
An index of population vulnerability to EHE was developed from a literature review. Threshold temperatures for EHE were defined using local temperatures, and indicators of increased morbidity. Spearman correlations determined the strength of the relationship between the VI and morbidity during EHE. The VI was mapped providing a visual guide of risk during EHE. Future changes in population vulnerability based on future population projections (2020-2030) were mapped.
Findings
The VI can be used to explain the spatial distribution of ESD during EHE. Mapping future changes in population density/demography indicated several areas currently showing high risk will continue to show increased risk.
Research limitations/implications
The limitations include using outdoor temperatures to determine health-related thresholds. Due to data restrictions three different measures of morbidity were used and aggregated to postal areas.
Practical implications
Identifying areas of increased service demand during EHE allows the development of proactive as-well-as reactive responses to heat. The model uses readily available data, is replicable in larger urban areas.
Social implications
The model allows emergency service providers to work with high risk communities to build resilience to heat exposure and subsequently save lives.
Originality/value
To the authors’ knowledge this triangulated approach using heat thresholds, ESD and projected changes in risk in a spatial framework has not been presented to date.

Abstract
We have pleasure in acknowledging the courtesy of the Public Health Authorities of the State of Queensland, Australia, for sending us this record. Want of space compels briefness, but we hope that the few points to which we have drawn notice may prove of interest to readers. We are concerned with the work of the Government Chemical Laboratory and local authorities so far as that relates to the purity, storage, and handling of the food supply. Action is taken under the Food and Drug sections of the Health Acts, and Regulations connected therewith. The difficulties naturally arising in the administration of a vast and sparsely populated tropical territory have been increased, there as here, by shortage of labour and materials of all kinds. So that schemes devised by local authorities in the interests of public health have in many instances been seriously delayed. The Chief of the Government Chemical Laboratory remarks that the Department has worked under incessant pressure for many years. “ The well informed, versatile and competent practitioners ” demanded by the service are not at present available outside the Government service, and “ unless they are forthcoming from time to time to rejuvenate the staff the laboratory may be reduced to a laboratory of professional labourers.”
