Environmental criminology
Encyclopedia
Environmental criminology focuses on criminal patterns within particular built environments and analyzes the impacts of these external variables on people's cognitive behavior. It forms a part of the Positivist School

In criminology, the Positivist School has attempted to find scientific objectivity for the measurement and quantification of criminal behavior.

Theory

Environmental criminology is the study of crime, criminality, and victimization

Victimology is the scientific study of victimization, including the relationships between victims and offenders, the interactions between victims and the criminal justice system — that is, the police and courts, and corrections officials — and the connections between victims and other social groups...

 as they relate, first, to particular places, and secondly, to the way that individuals and organizations shape their activities spatially, and in so doing are in turn influenced by place-based or spatial factors.

The environmental criminology approach was developed in the 1980s by Paul and Patricia Brantingham, putting focus of criminological study on environmental or context factors that can influence criminal activity. These include space (geography), time, law, offender, and target or victim. These five components are a necessary and sufficient condition, for without one, the other four, even together, will not constitute a criminal incident (Brantingham & Brantingham: 1991). Despite the obvious multi-faceted nature of crime, scholars and practitioners often attempt to study them separately. For instance, lawyers and political scientists focus on the legal dimension; sociologists, psychologists and civil rights groups generally look to the offenders and victims, while geographers concentrate upon the location of the event. Environmental criminologists examine the place and the time when the crime happened. They are interested in land usage, traffic patterns and street design, and the daily activities and movements of victims and offenders. Environmental criminologists often use maps to look for crime patterns, for example, using metric topology. (Verma & Lodha: 2002)

Practical applications

The study of the spatial patterns of crime and criminality has a long history. In the Chicago School

Crime prevention through environmental design is a multi-disciplinary approach to deterring criminal behavior through environmental design. CPTED strategies rely upon the ability to influence offender decisions that precede criminal acts...

(CPTED) is another practical application, based on the idea that situational factors such as the environment (poor lighting) can make crime more likely to occur at a particular time and place. CPTED measures to reduce the likelihood can include added lighting, making the place less conducive for crime.

Concentrated areas of high level of crime, known as crime hot spots, may have situational factors that help explain why the particular place is a problem. Could be that the place is poorly supervised, has poor "place management", has poor lighting or other characteristics. Changing some of those situational factors may help reduce levels of crime in that place.
