I. Introduction
1. The modern State seeks protection from crime
principally through the operations of the law enforcement
and criminal justice systems. These “formal” systems of
control serve the dual purpose of deterring law-breaking
among the population at large and of apprehending,
punishing and treating those who offend. Governments
have tried to improve the effectiveness of those systems by
such means as strengthening the police force, streamlining
the judicial process, diverting less serious offenders from
the system, increasing the severity of punishment for
serious crimes and widening the range of penal treatments
for recidivist offenders.
2. Complementing the formal system of control is what
criminologists refer to as society’s “informal” social
controls. These include a panoply of measures taken by
parents, schools and religious bodies to instil respect for
the law among children and young people, to regulate the
conduct of people as they go about their daily lives and to
afford protection to persons and property through routine
precautions and security measures.
3. The formal and informal systems of control depend
upon each other for their effectiveness. Without informal
social controls, the criminal justice system would soon be
swamped with a multitude of crimes, both more and less
serious, and would cease to function effectively. Equally,
without the existence of the criminal justice system to
impose the threat of arrest and punishment, informal social
controls would face a constant challenge to their legitimacy
and credibility.
4. As well as strengthening formal controls,
Governments have tried to bolster informal controls
through pronouncements about the duty of parents,
schools, communities and other social institutions to
promote the rule of law. More recently, as they have come
to recognize the limitations of the formal system in
controlling crime (and have had to meet its escalating
costs), Governments have begun to explore more direct
ways of improving informal social controls. Such activity
falls under the general heading of “crime prevention”,
which covers a very wide range of possible actions.
5. Several detailed classifications of crime prevention
have been developed by academic criminologists.
However, policy discussions usually distinguish between
just two kinds of prevention, social prevention and
situational prevention, which correspond to the two main
ways of preventing crime—reducing criminal motivation
and reducing crime opportunities. For the purposes of the
present discussion it is useful to distinguish among four
different general approaches (three of which seek to reduce
criminal motivation), which are distinguished by their own
set of objectives and techniques. These four approaches to
crime prevention are:
(a) Child development. Research has documented
a variety of risk factors in early childhood associated with
later delinquency and crime. It follows that interventions
designed to address those factors through improved
parenting skills, enriched early education and improved
physical and mental health could lead to large reductions
in future crime and delinquency;
(b) Community development. Ever since the
pioneering work of Shaw and McKay
1
in Chicago,
criminologists have recognized that powerful forces in
local communities can promote or inhibit crime. An
important strand of preventive work therefore consists of
efforts to strengthen the economic viability and social
cohesiveness of local communities, to provide more local
services and facilities for community enhancement, to
strengthen residents’ ties to their local communities, to
teach young people about the importance of the rule of law
and to develop local police-community relations. Sustained
efforts along those lines have recently been made in many
Western countries, most notably in France (the
Bonnemaison initiatives), the United Kingdom of Great
Britain and Northern Ireland (“safer city” programmes),
Italy (the anti-Mafia education of young people in
Palermo) and the United States of America (neighbourhood
watch and community policing);
(c) Social development. This is the least advanced
of the four approaches, but is of great interest in a United
Nations context. It proceeds on the assumption that in
developing countries and countries with economies in
transition much crime results from poverty, lack of paid
employment, poor education, discrimination and a variety
of other social and economic deprivations. It is assumed
that social development will remove these “causes” of
crime. Unfortunately, there is no direct relationship
between social conditions and crime. Thus, crime has
unexpectedly increased in Western countries in times of
increased affluence and improved social security. Crime
also shows no direct relationship to levels of employment
in Western countries. However, these findings may not
hold for developing countries and countries with
economies in transition, where the general social and
economic conditions are much less favourable;
A/CONF.187/7

(d) Situational crime prevention. Unlike the three
other forms of crime prevention, all of which seek to
reduce the motivation for crime, situational prevention
seeks to reduce opportunities for crime. This has been the
fastest growing variety of crime prevention in the past
20 years. It has come to be associated with the spectacular
rise of private policing and the private security industry in
Western countries during that period.
2
In its government-
sponsored forms it consists of crime prevention advertising
campaigns, efforts to influence city planning and
architectural design to promote a crime-free environment,
focused efforts to diagnose and remove opportunities for
highly specific forms of crime such as bank robbery or
residential burglary and, more recently, putting pressure on
business and industry to alter products and practices giving
rise to crime.
6. A large number of successes of situational prevention
have been documented,
3
many of which show that crime is
not merely displaced by situational prevention. This form
of prevention is now part of official crime control policy in
several European countries, including the United Kingdom,
the Netherlands and France. Even so, worries continue to
be expressed about the wider consequences for society of
pursuing this approach to prevention, in terms of erosion
of freedom and of unequal access to crime prevention
benefits.
7. In the present paper, a brief review of the current
status of these approaches is undertaken followed by a
discussion of the likely direction of future developments in
the face of current needs and future challenges. Special
attention will be given to implementation difficulties,
ethical considerations and the need for research and
evaluation.
II. Current status of crime prevention
8. It is only during the past 20 years that Governments
have devoted serious attention to crime prevention and that
it has become a subject for concentrated academic study.
Even so, remarkable progress has been made, namely:
(a) National crime prevention councils and
agencies (directly or indirectly supported by government)
have been established in many countries, including most of
those in western Europe, Australia, Canada and the United
States;
(b) Many community crime prevention
programmes have been implemented with government
support in developed countries. Sometimes this has been in
the form of demonstration projects, such as the safer cities
initiatives in the United Kingdom, and sometimes in the
form of generally available programmes such as
neighbourhood watch in the United States and the
Bonnemaison community development approach in France;
(c) These crime prevention programmes have had
a direct and visible effect on many aspects of people’s
everyday lives. Examples would include the adoption of
“defensible space” architecture in public housing (which
has contributed to the demolition of high-rise public
housing) and the widespread adoption of closed-circuit
television surveillance in town centres;
(d) Criminologists have greatly expanded writing
and research on crime prevention, as a result of which our
knowledge of the subject is much greater than it was
20 years ago. Many new concepts assisting with the design,
implementation and evaluation of crime prevention
programmes have been developed;
(e) A large number of evaluations, in particular of
situational prevention, have been published. Many of these
evaluations show tangible and sometimes dramatic
reductions in crime;
(f) The International Centre for the Prevention of
Crime, a not-for-profit non-governmental organization, has
been established in Montreal with support from a small
consortium of countries. It runs a Best Practice Bureau,
which identifies, compiles and disseminates information on
successful crime prevention.

III. New challenges
9. Despite the considerable progress of the past
20 years, many challenges lie ahead in developing the full
potential of crime prevention. Some of the challenges
result from unresolved ethical issues, implementation
problems and technical difficulties in evaluating the
effectiveness of crime prevention, which will be discussed
separately. In this section challenges resulting from two
main sources are identified: (a) the uneven development of
crime prevention and (b) the broad social, economic and
technological changes that are altering the nature of crime.
These challenges can be briefly stated as follows:
(a) In an era of “small government” marked by
continual pressure to reduce government expenditure, the
additional resources needed for crime prevention are
A/CONF.187/7
4
difficult to find. Officials are reluctant to reassign existing
criminal justice system resources to new crime prevention
programmes, in particular when the effectiveness of these
is in doubt. Even in countries where crime prevention is
now an established component of criminal policy, the
resources devoted to it are tiny compared with those
devoted to the criminal justice system;
(b) As mentioned previously, the theory and
practice of the main forms of crime prevention are
unequally developed. The most difficult challenge will be
finding the resources to support research on crime
prevention through social development, given that this
form of prevention is of greatest interest to developing
countries and countries with economies in transition;
(c) Crime prevention is a concept recognized
primarily in the developed world, but not all developed
countries have yet recognized its potential. This situation
is likely to change as the result of the wider dissemination
of information about the theory and practice of crime
prevention. The transfer of knowledge about crime
prevention from the more to the less developed world
presents a greater challenge. It is likely that situational
prevention can be adapted successfully to conditions in the
developing world. However, it is unclear whether the same
can be said of child development and community crime
prevention approaches, since these depend on a social
infrastructure that may not exist in developing countries
and countries with economies in transition. Furthermore,
it is unclear how technical assistance about crime
prevention can be delivered from the more developed to
the less developed parts of the world;
(d) To date, most crime prevention efforts have
been focused on traditional forms of crime, which provide
the bulk of the official crime statistics—predatory property
crimes, assaults, domestic violence and vandalism. It is
unclear whether the preventive approaches developed to
date can be applied more widely to other kinds of crime.
One significant group of these (discussed in section IV
below) includes organized and transnational crimes, but
there are many other crimes that have received little
preventive attention. These include child pornography,
corruption, fraud and economic crimes, hate crimes and
crimes against migrants and tourists;
(e) It is also unclear whether the crime prevention
approaches developed to date can be effectively applied to
prevent completely new forms of crime, such as those
associated with the Internet;
(f) This also holds true for the prevention of
terrorism, a form of crime that often combines elements of
violence with propaganda, politics and warfare. There is a
grey zone between violent crime and the crime of political
violence, which has only recently received scholarly
attention.
5
IV. The challenge of preventing
organized crime
10. Organized crime, whether national or transnational,
is widely perceived as a growing threat to civil society.
Many transnational crimes, such as drug-trafficking,
trafficking in humans and money-laundering, constitute a
particular threat to developing countries and countries with
economies in transition. These crimes seem likely to
increase with increased globalization and, with the
associated increase in international trade, the expansion of
business and leisure travel and the greater erosion of
political borders.
11. It is also widely recognized that traditional legal or
enforcement responses to organized crime cannot succeed
alone and must be combined with prevention. The Centre
for International Crime Prevention, in its role of coor-
dinating the preparation of the draft United Nations
Convention against Transnational Organized Crime, has
acknowledged that prevention is a core element of the
strategy (see articles 22 and 22 bis). Further, it is under-
stood that not every Member State will be in a position to
implement the Convention fully without technical assis-
tance from the United Nations. It is acknowledged that
only with this three-part strategy—legal response, preven-
tion and technical assistance—can Member States work
both nationally and internationally to curb the spread of
transnational organized crime.
12. Opinion and techniques vary on how to prevent
organized crime. To the extent that it thrives on disad-
vantage, social development, community development and
child development may all have a part to play in preven-
tion. The programme developed in Palermo to educate
people about the dangers of organized criminal groups is
one example. However, disadvantage is not the key to
understanding organized crime. Rather, the key seems to
be that in every society, developed or not, illegal oppor-
tunities abound to make large sums of money. It is these
opportunities which permit organized crime to flourish.
A/CONF.187/7
5
13. This being the case, the greatest preventive potential
may rest in the situational approach, but it must be adapted
to deal with the more planned, complex offences charac-
teristic of organized crime. This will demand detailed
research on the different forms of organized crime. Such
research must identify the sequence of tasks involved in
committing each form of organized crime and must
describe in detail how each task is accomplished. It may
turn out that the apparent complexity of organized crime
lies in the sequencing of tasks rather than in the nature of
the tasks themselves. Such research will clarify the
“opportunity structure” for each crime and at the same time
will suggest opportunity-blocking measures appropriate to
each stage of the crime. Little research of this kind has
been conducted, but many descriptions can be found in the
literature of the opportunity structure for different forms of
organized crime.
14. In addition, many examples exist of situational mea-
sures that are in use or have been proposed for use against
organized crime. These include:
(a) The installation of electronic tracking devices
in trucks, which wiped out organized thefts of trucks in
Rogers County, Oklahoma, United States. Similar devices
are being installed in cargo ships operating in south-east
Asia to prevent piracy;
(b) Restrictions on the international dialling capa-
bility of public pay phones in a New York City bus termi-
nal, which eliminated a multimillion-dollar organized
telephone fraud business;
(c) A variety of security changes introduced by
credit card companies in the United Kingdom, which saved
millions of pounds in organized credit card fraud in the
1980s and 1990s;
(d) Changes made in the 1980s in the design of
customs forms, which substantially increased the difficulty
of importing stolen motor vehicles into the United
Kingdom;
(e) The routine employment of certified investiga-
tive accounting firms to supervise the administration of
contracts in the construction industry, which was proposed
as a significant opportunity-blocking reform by the New
York State Task Force on Organized Crime;
(f) The increased regulation of bank secrecy,
which was identified in a recent United Nations report as
an important route to reducing opportunities for illegal
money-laundering.
V. New preventive concepts, strategies
and techniques
15. The increased attention being paid by Governments
to child development is a change of considerable signi-
ficance. Equally significant is that international bodies,
such as the United Nations and the World Bank, are
increasingly recognizing that the rule of law must precede
economic and social progress. This could ultimately result
in more international resources being channelled into crime
prevention through social development. These develop-
ments aside, most of the recent innovations in crime
prevention have been in situational and community
approaches. In fact, such approaches have developed so
rapidly that it is difficult to draw the line between what is
new and what is not. In any case, space permits the mention
of only the most significant new concepts, strategies and
techniques in the fields of community development and
situational prevention.
A. Community development
16. The topic of community involvement in crime pre-
vention will be covered comprehensively during the Tenth
Congress in its workshop on community involvement in
crime prevention. The most significant point is that there
is now widespread recognition of the need for partnerships
or multi-agency cooperation in community crime pre-
vention.
17. Experience in a variety of contexts has shown that
those partnerships cannot be sustained without a full-time
coordinator. This need has been met in a variety of ways.
For example, some central government community deve-
lopment demonstration projects have included funds for a
local coordinator. Where a longer-term investment in com-
munity development is contemplated, a choice has had to
be made between vesting leadership in the police or in the
local municipal authority. Further, it is understood that
effective community development requires partnerships to
be formed not only between police and local government,
but also with local business interests.
6
B. Situational crime prevention
18. Because of the concentrated injection of resources by
countries such as the United Kingdom and the Netherlands,
much progress has been made recently in the theory and
A/CONF.187/7
6
practice of situational crime prevention. Crime opportunity
theory has made many advances in the past decade, espe-
cially in the form of routine activities theory and rational
choice theory.
7
Some important new theoretical insights
have been produced concerning the interaction of so-called
root causes of crime (such as social deprivation, discrimi-
nation and inadequate parenting) and immediate situational
opportunities in producing crime. New concepts, such as
“repeat victimization”, referring to the tendency for crime
to be repeatedly visited on a small proportion of the total
population,
8
and “hot spots”, referring to the tendency for
crime to be tightly clustered in particular places, have
helped to focus situational prevention where it is likely to
be most effective. Finally, considerable progress has been
made in developing classifications and case studies of
effective means of reducing crime opportunities.
VI. Implementation difficulties
19. Implementation difficulties are broadly of two kinds:
(a) difficulties in persuading people to agree to the neces-
sary measures; and (b) difficulties in getting agreed-upon
measures implemented correctly. These difficulties are
encountered in all forms of crime prevention and are often
related to disputes about the ethical basis of the measures
(see below). In community development, as mentioned
above, most efforts to date have been focused on the
second kind of implementation difficulty, achieving the
necessary coordination among local agencies to implement
agreed-upon measures. The more difficult problem of laun-
ching community development initiatives in the most dis-
tressed neighbourhoods, which lack human resources and
basic organizational capacity, has been largely avoided. In
social development, the implementation difficulties are
presently focused on obtaining agreement about the neces-
sity and feasibility of this approach to crime prevention.
Subsequently, the issue of obtaining the needed resources
will have to be faced. In child development, the contro-
versies involve resource procurement and the ways in
which crime prevention goals should be combined with the
other goals of child development.
20. In situational prevention, both kinds of implemen-
tation difficulties have been widely encountered. For ins-
tance, various efforts to introduce gun controls in the
United States, designed to reduce the opportunity for lethal
violence, are currently being resisted by the National Rifle
Association and other members of the so-called gun lobby.
At the other end of the spectrum of seriousness, managers
of apartment buildings often find that their security
measures are defeated by residents who dislike the incon-
venience of having to lock building entrances every time
they go in or out.
21. As situational prevention becomes more focused on
achieving change in practices and products of business and
industry that generate crime, it seems likely to encounter
resistance on grounds of cost. For example, retail stores
often resist advice about ways to reduce shoplifting
because those methods also discourage impulse purchases.
Insurance companies may resist suggestions about tigh-
tening up procedures to check on fraudulent claims
because checking costs them more than simply paying all
claims with the minimum of checking. Vehicle manu-
facturers resist consumer group pressure to improve the
security of cars on the grounds that there is little public
demand for increased security. Ways of overcoming these
barriers to effective situational prevention are likely to be
the focus of considerable discussion in the next phase in
the development of situational prevention.
VII. Ethical issues, rights and
responsibilities
22. Most of the ethical concerns expressed about crime
prevention have been related to the situational approach
rather than to the other approaches discussed here. This is
because situational prevention seeks not to reduce criminal
motivation, but to reduce opportunities for crime. It is
therefore seen as a fundamentally more repressive app-
roach than the others, and critics claim that the use of
situational measures has many harmful consequences for
society. These threats have been identified as follows:
(a) The use of target-hardening and access-control
measures will lead to the development of a “fortress
society” in which people terrified of crime and distrustful
of others barricade themselves in their homes. This will
lead to the growing alienation of the population and the
gradual destruction of community life;
(b) The use of closed-circuit television and other
electronic means of surveillance fosters the development
of authoritarian, pervasive forms of social control and will
result in the erosion of important civil liberties;
(c) The increased use of security guards and
private policing leads to the social exclusion of the
homeless, minorities and unemployed young people from
A/CONF.187/7
7
public places such as shopping malls, parks and enter-
tainment facilities;
(d) The increased use of security devices leads to
the regimentation of society and means that law-abiding
citizens are forced to endure irksome and inconvenient
precautions such as security checks at building entrances
and the loss of luggage storage facilities;
(e) The insistence that members of the public take
precautions to protect themselves from crime results in
crime victims’ being blamed for their own misfortune. It
also results in women’s enduring significant restrictions on
going out at night and travelling alone;
(f) Because situational prevention can be expen-
sive, it can result in crime being displaced from the rich,
who can afford to take protective measures, to the poor,
who cannot afford to do so. It can also result in less serious
forms of crime being replaced by more violent crime as
offenders compensate for the increased difficulties they
face.
23. These criticisms have not gone unanswered.
9
It has
been argued, for example, that crime prevention through
environmental design encourages natural surveillance by
local residents of the streets and public areas around their
homes and can promote community cohesion. Surveys have
consistently shown that the public generally welcomes the
surveillance of public spaces through closed-circuit tele-
vision. Most people welcome information about routine
precautions they can take to protect themselves from crime.
Many publicly funded situational prevention measures
have been used to bring down unacceptably high rates of
crime in poor and deprived neighbourhoods.
24. However reasonable these and other defences may
be, it is clear that the ethics of situational prevention will
continue to be debated. Increasing experience of the other
crime prevention approaches will most probably also result
in ethical challenges. For instance, child development
approaches are sometimes accused, on the one hand, of
unfairly labelling as delinquent those singled out for
special treatment and, on the other, of rewarding the least
deserving members of the community. Community
development projects are also often the butt of accusations
of either preferential treatment or stigmatization of resi-
dents.
25. However, these and other social and ethical costs of
crime prevention have to be weighed against the potential
benefits of reducing the burden of crime on society and
reducing the harm that befalls individual people as a result
of victimization. The costs of prevention must also be
compared with the human and social costs of the criminal
justice system, which, despite the best efforts of jurists,
parliamentarians and officials, continues to be intrusive
and inequitable in its consequences.
26. Ethical concerns have been addressed in United
Nations efforts to establish international principles for the
implementation of crime prevention, most recently through
the convening of an expert group meeting in Buenos Aires
(8-10 September 1999) to consider elements of responsible
crime prevention. The resulting draft guidelines (see
annex), which build on those appearing in the annex to
Economic and Social Council resolution 1997/33, propose
that in their crime prevention plans Member States take
account of the main international instruments related to
human rights and crime prevention, such as the Convention
on the Rights of the Child (General Assembly resolu-
tion 44/25, annex), the Declaration on the Elimination of
Violence against Women (resolution 48/104), the United
Nations Guidelines for the Prevention of Juvenile Delin-
quency (The Riyadh Guidelines) (resolution 45/112,
annex), as well as the draft Vienna Declaration on Crime
and Justice: Meeting the Challenges of the Twenty-first
Century and the draft United Nations Convention against
Transnational Organized Crime.
VIII. Evaluation of crime prevention
27. Without evaluation, crime prevention practices can-
not be improved and, without hard evidence about effec-
tiveness, reliable information about best practices cannot
be disseminated. These points have been emphasized in a
variety of national and international strategy documents
concerned with crime prevention. Unfortunately, con-
siderable difficulties stand in the way of rigorous evalua-
tion. These difficulties can be divided into resource limita-
tions and technical problems.
28. One resource limitation is that the detailed crime data
needed for measuring the outcome of crime prevention
measures are frequently not available because statistical
record-keeping is deficient. A second important resource
limitation is the lack of trained personnel who are com-
petent to undertake evaluation studies. This is not a prob-
lem only for developing countries and countries with
economies in transition, but also for those developed
countries without a strong tradition of quantitative research
in the social sciences. In short supply everywhere is exper-
tise in undertaking cost-benefit evaluations.

Professional Advisory Council, 1998).
29. The different approaches to crime prevention cannot
all be evaluated in the same way, and the technical prob-
lems encountered vary considerably with each approach.
Social development approaches can be evaluated only
using econometric techniques that compare crime rates
before and after the implementation of development pro-
grammes or that compare countries at different levels of
economic and social development. Evaluations of child
development approaches, unlike the other crime prevention
approaches, can in theory make use of rigorous experi-
mental designs. However, randomly dividing children bet-
ween treatment and control groups raises ethical and
practical difficulties. In addition, it is difficult to measure
long-term reductions in delinquency and crime through a
child development approach. In evaluating community
development, two main difficulties are encountered:
(a) because a package of measures is usually implemented,
it may be impossible to identify which of the measures, if
any, is principally responsible for success and (b) because
a number of objectives are often sought by the different
partners, it may not always be possible to measure out-
comes in ways that meet each partner’s concerns.
30. Situational crime prevention techniques have been
subjected to the greatest number of separate evalua-
tions—more than 100 to date. In one respect, the effects of
situational prevention are easier to measure. This is
because reductions are sought in highly specific forms of
crime and, if the measures are effective, those reductions
should become apparent immediately.
31. It is rarely possible to conduct true experiments when
evaluating situational prevention, and most evaluations of
this approach rely on weaker time series or quasi-
experimental designs. This makes it difficult to know for
sure whether any reductions in crime are due to the
preventive measures implemented. One solution to this
problem may lie in the much clearer specification of the
mechanisms by which the situational prevention measures
achieve their effect on crime. Evaluations would then be as
much focused on the process of implementing measures as
on the results of the measures.
10
32. A second general difficulty in evaluating situational
prevention is that there is always the possibility that
situational measures have led to crime’s being merely dis-
placed, not reduced. In fact, most evaluations to date have
found rather little evidence of displacement.
11
In a review
conducted for the Ministry of Justice of the Netherlands,
Hesseling reported that in only 33 out of 55 situational
prevention projects was there any sign of displacement.
12
Furthermore, in none of the 33 studies was displacement
complete. Instead, some crime prevention benefits were
obtained in every case.
33. This work on displacement has led to the discovery
of the phenomenon of “diffusion of benefits”. This term
refers to the fact that situational prevention often results in
reductions not just in the crimes targeted by the measures,
but also in crimes that have not been targeted.
13
It seems
that potential offenders often overestimate the power or the
reach of the measures that have been taken. Designing
evaluations that simultaneously measure both possible
displacement and diffusion of benefits will present signi-
ficant technical challenges to the academic community.
34. Already a sufficient number of evaluations of crime
prevention measures have been reported, so that meta-
analyses (in which the results of separate evaluations are
systematically compared within a common framework) can
be undertaken.
3
This kind of comparison is important
because individual studies do not always point in the same
direction. This fact permits unsound preventive approaches
to survive longer than they should. Meta-evaluations pro-
vide a methodology for taking account of small
inconsistencies between studies to reach the most reliable
conclusions about the effectiveness of particular app-
roaches. As more crime prevention projects are subjected
to evaluation, meta-evaluations will become increasingly
feasible and will play an increasing part in the development
of crime prevention policy.

Revised draft elements of responsible crime prevention,
prepared by the Expert Group Meeting on Elements of
Responsible Crime Prevention: Addressing Traditional
and Emerging Crime Problems, held in Buenos Aires
from 8 to 10 September 1999
I. The concept of crime prevention
1. Crime prevention, for the purpose of these revised draft elements of responsible
crime prevention, refers to strategies and initiatives that seek to promote safety and
security and that do not resort to formal criminal justice sanctions.
2. Crime prevention should address all forms of crime, violence, victimization and
insecurity and take into account the growing internationalization of criminal activities.
3. Crime prevention is subdivided into approaches focusing on potential offenders,
potential victims and situations. Crime prevention consists of: (a) primary prevention,
which typically targets the social factors and psychological problems that predispose
persons to offending and/or victimization; (b) secondary prevention, which includes
measures directed at persons at risk of becoming offenders and/or victims; and (c) tertiary
prevention, which involves measures to prevent recidivism among former offenders
through social reintegration and/or treatment, as well as services to support victims.
II. Promoting and sustaining responsible crime prevention
A. Basic principles
4. Governments should play a leadership role in the promotion of safer communities
through the creation and maintenance of a national strategy that acknowledges crime
prevention as an essential component of social development.
5. Crime prevention strategies at the national, regional and local levels should be
characterized by a multisectoral approach that includes members of the community as
integral and essential partners in all stages of the planning and implementation of a crime
prevention programme and that respects different social realities, cultures and genders.
6. Crime prevention strategies at the national, regional and local levels should address
the root causes and risk factors of crime and victimization through social, economic, health
and educational policies. Where appropriate, crime prevention programmes should be
linked to comprehensive programmes addressing social marginalization and exclusion,
with particular emphasis on families and children at risk. Crime prevention strategies
targeting groups at risk of becoming offenders, especially youth, should be promoted and
should include educational opportunities, employment, housing and leisure facilities.
A/CONF.187/7

7. The prevention of crime and violence and the promotion of community safety should
be a horizontal priority in the planning and management of cities.
8. Governments should strive to achieve sustainability of their crime prevention
strategies through consideration of the following means: assessment of the distribution of
resources between crime prevention and the other elements of the criminal justice system
with a view to encouraging adequate resources for effective and timely prevention of crime
and victimization; clear accountability for funding, programming and coordinating crime
prevention initiatives; and the encouragement of community involvement in sustainability.
9. Partners in the implementation of prevention programmes, including law enforcement
and health professionals, should have clearly defined and transparent roles.
10. Law should define the limits within which the private security sector may act. The
private security sector should, in accordance with human rights standards, not exercise any
function that, by its nature, is incompatible with the rule of law and the principle that the
use of force is reserved for the State.
11. The development of national crime prevention strategies should foster commonalities
between local and global crime prevention objectives.
12. Under all circumstances, crime prevention measures should be carried out in strict
conformity with the relevant provisions of international law and international standards of
human rights.
B. Tools and methodologies
13. Governments should establish special councils or other agencies specifically
mandated to exercise the necessary leadership to draw up plans of action that define
priorities, establish linkages and coordinate with relevant ministries, foster partnerships
with non-governmental organizations and the business, private and professional sectors at
the national, regional and local levels and develop and provide the tools necessary for
communities to address crime problems.
14. A national crime prevention strategy should possess the capacity to identify trends
and risk factors and be forward-looking by encouraging the development of early-warning
systems and/or indicators that Governments might use to better anticipate various forms
of criminality, taking into account both their local and their global dimensions.
15. Crime prevention strategies should encourage the development of the following:
rigorous diagnosis, an action plan, an implementation strategy and an evaluation of
effectiveness. These steps should involve multiple sectors and key partners of the com-
munity, including the citizens, with a view to establishing a coalition that is capable of
exercising strong leadership and that draws upon the most promising practices.
16. To promote prevention, provisions should be made available or strengthened for a
range of mechanisms for mediation and informal conflict resolution.
17. Situational crime prevention programmes should be developed, including target-
hardening, environmental design and surveillance. These programmes should not unduly
reduce the quality of the built environment or limit free access to the public domain or
public facilities, nor should they infringe on personal privacy.
18. Crime prevention strategies should contain a dynamic public education and
awareness-building component that addresses the following: the provision of information
A/CONF.187/7
12
concerning effective strategies and techniques to relevant actors; the active engagement of
the community in all aspects of the strategy; the accurate presentation of the crime problem
and effective ways to respond to it, including measures that citizens can take to assist in the
strategy; and the building of confidence in the formal institutions that make up the criminal
justice system.
19. The strategy should ensure that crime prevention interventions are evaluated.
Evaluations should consider not just the effects on crime but also wider benefits, such as
a reduction in fear or improved confidence among stakeholders in problem-solving
processes. Possible costs of the intervention should also be assessed, such as the dis-
placement of crime or potential infringements of privacy and liberty. For promising
interventions, evaluations should seek to identify ways to improve them and, through cost-
effective assessments, suggest measures to sustain them.
III. International cooperation
20. Member States, in creating an international crime prevention framework, should set
out meaningful, achievable and concrete tasks that take into account the main international
instruments related to human rights and crime prevention, such as the Convention on the
Rights of the Child (General Assembly resolution 44/25, annex), the Declaration on the
Elimination of Violence against Women (resolution 48/104), the United Nations Guide-
lines for the Prevention of Juvenile Delinquency (The Ryadh Guidelines) (resolu-
tion 45/112, annex), as well as the draft Vienna Declaration on Crime and Justice: Meeting
the Challenges of the Twenty-first Century and the draft United Nations Convention
against Transnational Organized Crime.
21. The strategy should be consistent and supportive of other relevant United Nations
norms and standards in crime prevention and criminal justice.
22. The international exchange of information on the most promising practices, in terms
of both effectiveness and respect for human rights, should be facilitated.
23. Technical assistance to Governments for the development and implementation of
effective crime prevention and community safety strategies at the national, regional and
local levels should be provided in accordance with the above-mentioned norms and
standards.
