Addressing the situational consequences of weather on crime is part of CPTED.
Changes in weather affect crime rates and crime risks - both locally and over wider areas.
For example, violent crime rates increase with temperature increases and burglary rates fall when the weather is bad (i.e. cold, raining, stormy, windy).
People change their routine behaviors depending on weather. Weather also has an effect on peoples emotions and tolerance - particularly heat. Weather affects people's rates of alcohol and drug consumption with subsequent changes in crime. In some locations, weather affects people's wages and economic needs and that drives crime also.
Weather 'shocks' (different weather than normal for the season) result in changes to crime rates - both immediately and following the weather shocks.
Crime is typically displaced over time and/or place by weather shocks.
In other words, if burglary is too difficult today becasue of weather or other shocks (including 'hot spot' policing), then it can be displaced to another place or another time and add to the crime rates then or there.
Findings are similar across Australia, China, Korea, India, New Zealand, South Africa, US and UK.
There are also contradictions - e.g. homicide rates in some places are independent of temperature.
Understanding the effects of weather on crime enables the design of better CPTED outcomes.
Example: CPTED advice on ia 2nd repeat burglary at a cafe during a long ongoing summmer heatwave will likely be different from advice for if the offence was in the middle of a characteristically cool winter. (CPTED advice for summer would be to make protective changes immediately to avoid another repeat burglary. In contrast, in winter cooler weather, the risks of a 3rd repeat burglary would be lower and offer more time to make changes.)
In the longer term, crime rates for many crime types are predicted to rise proportionally each year as a result of global warming and climate change.
For global warming, it is better to invest now in reducing crime, to reduce proportional increases in crime in later years.
This practical 2-day CPTED training for Community Safety Officers is informative, practical and fun - the best way to learn!
1. CPTED is the most cost-effective way to reduce crime and anti-social behaviour in Community Safety 2. Provide CPTED advice to members of the public.
3. Design CPTED solutions to reduce crime
4. Undertake crime risk assessments and CPTED audits 4. Create crime prevention benefits of CPTED at almost zero cost.
The training covers:
Using CPTED in Community Safety contexts Threats, Risks and Vulnerabilities Use 12 CPTED principles to reduce crime Crime Risk Assessments to save cost Working with members of the public Undertaking CPTED building and site audits Using targeted CPTED Reduce repeat victimisation Use CCTV in CPTED Managing anti-social behaviour Reducing fear of crime Practical real world CPTED team exercise (desktop and/or site) Practical CPTED planning
Training is by presentations,small group exercises, group discussions and a practical exercise.
The course includes a workbook, certificate, refreshments.
An individualised CPTED Training Certificate is awarded to those who complete the course.
Willetton Sports Precinct in Western Australia uses CPTED effectively in many ways to reduce crime and anti-social behaviour.
The sports precinct is large and includes many first-class facilities.
Three examples of excellent CPTED stand out:
* The decision to move a skatepark to a better location (in CPTED terms) within the precinct to provide better natural surveillance and disrupt unlepful routine behaviours. This is accompanied by pedestrianisation changes to external roads to create a large pedestrian precinct integrated with a shopping mall.
* The use of multi-level and multi-intensity lighting for different scenarios. On the same pole are high-level high-intensity floodlights and independently operated low -level variable-intensity motion-triggered lighting. This is especially effective on the central 'spine' route linking different parts of the precinct.
* The use of 'transparent' fencing to provide extensive natural surveillance and control routine pedestrian movements. This transparent fencing is complemented by opaque walls blocking views of potential crime opportunities in secured private areas.

Alongside our CPTED training and CPTED review work, we undertake a lot of CPTED research.
Each project results in a collection of useful CPTED and crime prevention information on that topic.
