abstract
Despite highly specialised and capable emergency management systems, ordinary citizens are usually
first on the scene in an emergency or disaster, and remain long after official services have ceased. Citizens
often play vital roles in helping those affected to respond and recover, and can provide invaluable as-
sistance to official agencies. However, in most developed countries, emergency and disaster management
relies largely on a workforce of professionals and, to varying degrees, volunteers affiliated with official
agencies. Those who work outside of such systems have tended to be viewed as a nuisance or liability,
and their efforts are often undervalued. Given increasing disaster risk worldwide due to population
growth, urban development and climate change, it is likely that ‘informal’volunteers will provide much
of the additional surge capacity required to respond to more frequent emergencies and disasters in the
future. This paper considers the role of informal volunteers in emergency and disaster management.
Definitions of volunteerism are reviewed and it is argued that there is an overemphasis on volunteering
within, and for, state and formal organisations. We offer a broader definition of ‘informal volunteerism’
that recognises the many ways ordinary citizens volunteer their time, knowledge, skills and resources to
help others in times of crisis. Two broad types of informal volunteerism are identified –emergent and
extending –and the implications for emergency and disaster management are considered. Particular
attention is given to increasing ‘digital volunteerism’due to the greater accessibility of sophisticated but
simple information and communication technologies. Culture and legal liability are identified as key
barriers to greater participation of informal volunteers. We argue that more adaptive and inclusive
models of emergency and disaster management are needed to harness the capacities and resilience that
exist within and across communities.

1. Introduction
Despite highly specialised and capable emergency manage-
ment systems, ordinary citizens are usually first on the scene in an
emergency or disaster and remain long after official services have
ceased. Citizens may play vital roles in helping those affected to
respond and recover, and can provide invaluable assistance to of-
ficial agencies. For example, following the 2009 ‘Black Saturday’
bushfires in Victoria, Australia, citizens responded to farmers' calls
for help to rebuild farm fences. The success of these efforts led to
the formation of ‘BlazeAid’, a community organisation that re-
builds fences and provides support to rural communities affected
by fire, flood and other hazards
1
.New technologies and social
media have also enabled citizens to participate in emergency and
disaster management in new ways [35,55,38]. This was evident in
March 2014 when 2.3 million people joined the search for missing
Malaysian Airlines flight MH370 by scanning more than 24,00 0
square kilometres of satellite imagery uploaded to the Tomnod
website [33].
Citizen participation is a key principle of disaster risk reduction
and resilience building (e.g. [87,27,16,12]). However, in most de-
veloped countries, emergency and disaster management relies
largely on a workforce of professionals and, to varying degrees,
volunteers affiliated with official agencies [2]. Individuals and
groups who work outside of this system have tended to be viewed
as a nuisance or liability, and their efforts are often undervalued
[34,41,77,83]. Given increasing disaster risk worldwide due to
population growth, urban development and climate change [32],it
is likely that ‘informal’volunteers will provide much of the addi-
tional surge capacity required to respond to more frequent
emergencies and disasters in the future.
This paper examines the role of informal volunteers in emer-
gency and disaster management. It explores the ways ordinary ci-
tizens volunteer their time, knowledge, skills and resources to help
others in times of crisis. A brief overview of research on citizen
action in emergencies and disasters is provided, and definitions of
volunteerism are examined and considered in the context of
emergency and disaster management. We argue that less rigid de-
finitions of volunteerism are needed to fully recognise and value
citizen contributions in this space. The paper then identifies
‘emergent’and ‘extending’volunteerism as two main types of in-
formal volunteerism and discusses the implications for emergency
and disaster management. Particular attention is given to increasing
‘digital volunteerism’resulting from greater accessibility and so-
phistication of information and communication technologies and
changing preferences for volunteering. Culture and legal liability are
identified as key barriers to greater participation of informal vo-
lunteers. We argue that more adaptive and inclusive models of
emergency and disaster management are needed to harness the
capacities and resilience that exist within and across communities,
and that attempts to command and control citizen action are mis-
guided and may be counterproductive.
2. Citizen action in emergencies and disasters
The roles played by citizens in emergency and disaster man-
agement are widely documented in disaster research. Research
challenges the popular perception that disasters unleash chaos
and disorganisation, with citizens becoming passive victims,
panic-stricken, or engaging in antisocial behaviours such as loot-
ing. Rather, individuals and groups have generally been found
to become more cohesive than in ‘normal’times, commonly
working together to overcome disaster-induced challenges (e.g.
[34,41,64,77,83]). Sociological research in particular has provided
important insights into collective behaviour and organisational
responses to emergencies and disasters. A key contribution of this
work is the documentation and analysis of emergent behaviours,
groups and organisations in times of crisis (see [21]).
Early disaster studies examined the phenomenon of ‘con-
vergence’, a process involving the informal movement of people,
messages and equipment into disaster-affected areas [34,9]. Con-
trary to popular views of chaos and disorganisation, Fritz and
Mathewson [34] observed that survivors tend to be more passive,
cooperative and ‘subject to social control’by emergency services
than those who converge on the scene from the outside. More
recently Kendra and Wachtendorf [47] identified seven types of
‘converger’from responses to the 2001 World Trade Center dis-
aster. These included: returnees; the anxious (seeking information
about family and friends); helpers; the curious; exploiters; sup-
porters (encouraging and expressing gratitude to emergency
workers); and mourners and memorialisers. While motivations for
the unaffected to enter disaster-affected areas vary, convergence
can be expected to occur in most emergencies and disasters.
Despite most citizens' good intentions, convergence can create
problems and challenges for emergency managers. Auf der Heide
[6] notes that hospitals and other emergency response organisa-
tions are often inundated by information requests and donations.
Unsolicited donations may be inappropriate or unnecessary and
require the expenditure of resources for their management or
disposal [43]. This can impede emergency services' work, parti-
cularly when transportation and communications infrastructure
are overloaded. However, as Auf der Heide stresses, convergence is
not always detrimental and ‘local authorities need to recognise
that unsolicited volunteers will show up, and procedures must be
developed for processing these volunteers and integrating them
into the response’([6], p. 465).
Initial studies of convergence led to growing interest in col-
lective behaviour and the role of community and other groups in
emergency and disaster response. Researchers at the Disaster Re-
search Centre (DRC) developed a fourfold typology of organised
response to disasters based on a detailed examination of field
studies [22,67]. The typology identifies four types of organisation
based on a classification of tasks (regular and non-regular) and
structure (old or new) (Table 1). Type I –Established organisations
involve routine tasks performed through existing structures;
for example, fire fighting performed by a state fire agency. Type II –
Expanding organisations undertake regular tasks through new
structures. These are typically volunteer associations or groups
whose core activities are non-emergency related but have latent
emergency functions. An example of an expanding organisation is
the Salvation Army [75], which has a core mission ‘to feed, to
clothe, to comfort, [and] to care’for those in need, but historically

has become involved in disaster relief when needed. The ‘expan-
sion’occurs because people who are not involved in the organi-
sation′s normal activities become active participants as the
emergency function is activated, and the group takes on tradi-
tional but not everyday tasks. Type III –Extending organisations
have established structures but take on new and unexpected
functions during the emergency period. A logging company, for
instance, might send bulldozer operators and equipment to help
clear debris after a wildfire, while a sporting club or religious
group might mobilise its members to deliver food and clothing to
those who lost their home. Although extending organisations of-
ten work in conjunction with established and expanding organi-
sations, they can present challenges because they do not come
under the effective control of the latter. Finally, Type IV –Emergent
organisations are groups with new structures and new tasks. They
emerge when needs are not being met, or it is perceived that
needs are not being met, by other organisations. Emergent groups
often form during or immediately after the emergency period,
before established and extending organisations arrive. These
groups often play critical ‘first responder’roles such as initial
search and rescue, providing first aid to victims, and assessing
damages and community needs. Like extending organisations,
they can pose significant challenges for emergency managers [22].
The DRC typology provides a useful framework for understanding
different types of emergency volunteering.
3. Volunteerism in emergencies and disasters
Despite the key roles ordinary people play in times of crisis,
officials often consider their actions as somehow external to or
separate from the formal emergency and disaster management
system [77]. Professionals and volunteers with official agencies
tend to be viewed as legitimate actors, while those who are not
part of the system are often seen as illegitimate, impeding effective
response, and requiring management. Ordinary people can obtain
legitimacy by becoming part of the system, usually as an accre-
dited or formally affiliated volunteer. This is apparent in agencies'
attempts to recruit (or incorporate) volunteers, for example, as
volunteer firefighters (e.g. [18]), through Community Emergency
Response Teams (e.g. [30]) and attempts to register unaffiliated
volunteers prior to an emergency (e.g. [20]). In this section, defi-
nitions of volunteerism are reviewed. We argue that there has
been a tendency to define volunteerism narrowly, largely exclud-
ing those who act independently of the state or formal
organisations.
3.1. Defining volunteerism
In simple terms, volunteering refers to ‘any activity in which
time is given freely to benefit another person, group or organisa-
tion’([93], p. 215). In volunteerism research, the term is generally
used to refer to activities that are non-obligatory (there is no
contractual, familial or friendship obligation between the helper
and the helped, nor coercion); undertaken for the benefitof
others, society as a whole, or a specific organisation; unpaid;
and undertaken in an organised context [15,19,65,82,93,94].
Nevertheless, there is considerable debate as to what activities
constitute volunteerism and who can be considered a volunteer.
Cnaan et al. [15] reviewed definitions of volunteerism across a
range of sectors. Definitions varied according to an author or orga-
nisation′s position on four key dimensions: free choice; remunera-
tion; structure; and intended beneficiaries. The strictest definitions
held that volunteerism must: be entirely voluntary and entail no
coercion; involve no reward or even personal interest in the vo-
luntary activity; be undertaken through a formal organisation; and
involve no relationship or similarities (e.g. ethnicity) between vo-
lunteers and beneficiaries. Broader definitions included activities
that: involve degrees of coercion (e.g. volunteering as part of a
school programme); remuneration below the value of work and
services provided; are undertaken outside of formal organisations;
involve people of similar backgrounds (e.g. ethnic, religious, gender
or residential groups) and even volunteers as beneficiaries (e.g. self-
help groups) [15]. Strict definitions are problematic because freedom
of choice and the nature of rewards may be known only to volun-
teers (e.g. a person who volunteers out of a sense of religious or
moral obligation, or to improve their job prospects). Furthermore,
restricting volunteerism to activities undertaken through formal
organisations obscures the enormous amount of work undertaken
by people in countries and communities where formal, non-gov-
ernment organisations are absent or under-developed [85,94].
Moreover, in some cultures, western concepts of volunteering may
be alien, with other understandings of helping behaviour domi-
nant. Robinson and Williams ([72],p.69),forexample,explainthat
in Māori culture: ‘The idea of ‘public service’, which is not voluntary
in the sense of being an optional activity, should be distinguished
from volunteering carried out by choice. It is a function of citizen-
ship, a requirement of belonging to a community. In the Māori
community, it is a cultural obligation’. Similarly, Kerr et al. [49] note
that cultural and linguistic differences mean that much volunteer-
like activity in Australian Aboriginal and Torres Strait Islander
communities ‘is generally not acknowledged, fails to attract both
material support and wider recognition, is not formalised and op-
erates within the community-accepted frames of reference parti-
cular to that community’. They argue that the concept of vo-
lunteering should be extended to include different meanings given
to helping behaviour in order to recognise and appreciate the ex-
periences of those who work outside of mainstream organisations
and dominant paradigms.
Time commitment is another important dimension in vo-
lunteerism. Volunteering is commonly characterised as an activity
where people ‘give their time’(e.g. [95], p. 695) and is often de-
limited to activities that ‘extend over time’([82],p.3)orare‘long-
term’([63], p. 646). For example, Penner defines volunteerism in
terms of planned, long-term action: ‘people think and weigh their
options before they make the decision to volunteer. In this respect
volunteerism can be contrasted with bystander interventions,
which are usually quite time limited’([63], p. 646). This distinction
between bystander interventions and volunteering is based on an
assumption that crisis situations provide limited opportunities for
the types of deliberation that are apparently necessary for vo-
lunteerism. According to Snyder and Omoto ([82], p. 3), emergen-
cies and disasters ‘…offer little opportunity for foresight and ad-
vance planning and usually demand immediate and instantaneous
responses’. However, research reviewed in this paper (below) de-
monstrates that citizen responses to emergencies and disasters are
usually deliberate and constitute much more than ‘bystander in-
terventions’, even when time commitment is minimal.

3.2. Volunteerism in emergencies and disasters
Volunteerism has tended to be defined more broadly in
emergency and disaster contexts. Definitions typically focus on
volunteer activities and outcomes rather than volunteers’char-
acteristics and motivations per se. For example, in an early paper
on volunteerism in disaster situations, Shaskolsky ([78],p.8)
defined volunteerism as ‘any act that is orientated to the direct or
indirect service of some other person or thing regardless of whe-
ther or not such act serves the self-interest of the actor’. Similarly,
Wolensky [96] argued that volunteerism has too often been de-
fined in altruistic terms and in relation to higher-level needs such
as learning, exploration and self-actualisation, meaning that vo-
luntary activities motivated by self-interest, egoism and power are
overlooked. Wolensky regards volunteerism as ‘any monetarily
uncompensated, wilful action, be it spontaneous or organised,
oriented toward the protection and/or restoration of symbols, in-
terests, people, or other high priority values of a personal or group
nature’([96], p. 35).
According to Shaskolsky [78] volunteerism takes four forms in
disaster situations. Anticipated individual volunteers fulfil the gen-
eral expectations of society on an individual basis, such as a doctor
who comes to the aid of victims. Anticipated organisation volun-
teers are regularly associated with an organisation, such as a vo-
lunteer fire brigade or the Red Cross, and whose participation is
expected and planned for. Spontaneous individual volunteers
provide assistance as individuals, usually in the early stages of a
disaster, for example in search and rescue activities. Spontaneous
organisation volunteers place themselves at the service of an or-
ganisation only once an emergency or disaster has occurred. These
volunteers may choose to: (a) help a regular disaster organisation;
(b) formally create an ad hoc organisation for dealing with the
circumstances of the specific disaster; (c) use their pre-existing,
non-disaster organisation for disaster work; or (d) carry out dis-
aster-related tasks within a loose, informal network.
In a similar vein, Wolensky [96] identified four types of ‘post-
impact’volunteerism. Public interest emergent volunteerism in-
cludes groups such as search and rescue crews, those who help
clean up after disaster, and those who assist with shelter and
housing efforts. Such volunteerism is considered altruistic due to
volunteers’genuine concerns for human safety and community
welfare. Public interest organisational volunteerism is considered
communalistic as it involves regular and non-regular aid provided
through emergency services, civil defence and other organisations
that act in the interests of the entire community. Private interest
emergent volunteerism involves citizen action and self-help groups
that organise to protect their own interests following disaster.
These groups are considered egoistic because they primarily serve
members’interests. Private interest organisational volunteerism
involves organisations such as churches, unions and clubs that
provide assistance primarily to members. It is considered mutua-
listic because help is provided to people who share common
characteristics and interests.
Emergency management agencies have tended to adopt more
formal, operational definitions of volunteerism. For example,
the US Federal Emergency Management Agency [29] defines a
volunteer in the context of the National Incident Management
System: ‘a volunteer is any individual accepted to perform services
by the lead agency (which has authority to accept volunteer
services) when the individual performs services without promise,
expectation, or receipt of compensation for services performed’.
Similarly, Emergency Management Australia
3
([26],p.114)defines
a‘volunteer emergency worker’as someone who ‘engages in
emergency activity at the request (either directly or indirectly) or
with the express or implied consent of the Chief Executive
(however designated), or of a person acting with the authority of
the Chief Executive of an agency to which either the State emer-
gency response or recovery plan applies’. Such definitions place
the volunteer within the ambit of formal emergency management
systems, in which volunteers act in accordance with the legisla-
tion, policies and procedures of the organisations they are af-
filiated with. Participation that is invited or requested by an
agency or some other authority may not be voluntary if there is a
real or perceived obligation. Training and accreditation is often a
key requirement of formal volunteering [11].
While most agencies retain these formal, operational defini-
tions, the participation of ‘unofficial’,‘unaffiliated’,‘informal’and
‘spontaneous’volunteers is increasingly recognised. For example,
the Australian Government’s([7],p.5)Spontaneous Volunteer
Management Resource Kit defines spontaneous volunteers as ‘in-
dividuals or groups of people who seek or are invited to contribute
their assistance during and/or after an event, and who are un-
affiliated with any part of the existing official emergency man-
agement response and recovery system and may or may not have
relevant training, skills or experience’. Similarly, FEMA [28] dis-
tinguishes between affiliated and unaffiliated volunteers, with the
latter defined as ‘individuals who offer to help or self-deploy to
assist in emergency situations without fully coordinating their
activities’. FEMA notes that although unaffiliated volunteers can be
a significant resource, the lack of pre-established relationships
with emergency management agencies can make it difficult to
verify their training or credentials and match their skills to ap-
propriate service areas. Despite this broadening perspective, most
agencies are concerned with managing volunteers and integrating
them into official responses.
3.3. Defining ′informal volunteerism′
Discussion thus far has highlighted the restrictive nature of
definitions in volunteerism research and, to a lesser degree, in
emergency and disaster management (see Table 2). Volunteerism
has typically been defined in terms of deliberately chosen and
planned, long-term activities that are undertaken through formal
organisations. In emergency and disasters, volunteerism has ten-
ded to be defined in terms of participation in the activities of state
or other organisations, with whom the volunteer is formally af-
filiated. Despite increasing recognition of the participation of un-
affiliated or ‘spontaneous’volunteers, most agencies are con-
cerned with managing volunteers and integrating them into offi-
cial responses. Such definitions exclude those who act in-
dependently of the state or formal organisations, and obscure
much of the shorter-term, informal volunteering that occurs in
times of crisis. Thus we challenge the assertion that volunteering
must be long-term and undertaken through formal organisations,
and argue for greater recognition and participation of informal
volunteers.
In this paper, informal volunteerism refers to the activities of
people who work outside of formal emergency and disaster
management arrangements to help others who are at risk or are
affected by emergencies and disasters. Such volunteerism may
take place before, during or after an event. Informal volunteers
may participate as individuals or as part of a group, on a short or
longer-term basis, regularly or irregularly, and in situ or ex situ.

problem’([63], p. 46).

Their participation may be spontaneous and unplanned, or delib-
erate and carefully planned.
4. Informal volunteerism: types and roles
There are many ways that citizens can participate in emergency
and disaster management informally. In this section, two broad
types of informal volunteerism are identified: ‘emergent vo-
lunteerism’and ‘extending volunteerism’.‘Digital volunteerism’is
identified as a new mode of volunteering, driven by the increasing
accessibility and sophistication of information and communication
technologies, and may be emergent or extending.
4.1. Emergent volunteerism
Emergent volunteerism involves new forms of volunteering
that occur in response to unmet needs, whether perceived or real.
Researchers and emergency managers have tended to focus on
challenges associated with ‘spontaneous’volunteers, usually once
an emergency or disaster has begun (e.g. [8,17,31,51,76]). However,
it is important to recognise that new forms of volunteerism may
emerge beforehand, for example in prevention and preparedness
activities, and may entail considerable deliberation, planning and
organisation [21,68,83]. For this reason, we prefer the term
‘emergent’.
Cottrell ([17],p.3)defines ‘spontaneous’volunteers as ‘those
who seek to contribute on impulse –people who offer assistance
following a disaster and who are not previously affiliated with
recognised volunteer agencies and may or may not have relevant
training, skills or experience’. Spontaneous volunteers’proximity
to the emergency or disaster site means they often play critical
roles in first response. For example, in the 1976 Tangshan earth-
quake in China as many as 300,000 people crawled out of the
debris, with many going on to form rescue teams that saved 80
percent of those buried under the debris [61]. Other examples of
spontaneous volunteers include youths who performed search and
rescue operations following the 1985 Mexico City Earthquake [13]
and the one million volunteers from Japan and abroad who came
forward in response to the 1995 Kobe earthquake [79]. However,
while spontaneous volunteerism should be expected and planned
for, it cannot be relied upon. Helsoot and Ruitenberg [41] docu-
ment situations where trauma associated with mass fatalities has
rendered citizens passive, and where cultural factors have led to
nonresponse and a reliance on emergency services.
Improvisation and innovation are key features of emergent
volunteerism. Extreme events often present unforseen conditions
and problems, requiring capacities to improvise and innovate
[36]. Studies of improvisation and innovation in emergencies
and disasters have tended to focus on formal organisations
(e.g. [36,73,56,90]). However, Kendra and Wachtendorf ([48]
p. 318) consider community innovation and disasters, noting that
innovation is a capacity or process whereby a community ‘…does
something new in the face of crisis, either a crisis that is potential
or one that is realized’. Many innovative strategies and uses of
resources occur in the response phase where urgent need over-
comes most objections. The risk of maladaptive or suboptimal
outcomes tends to be considered an acceptable risk due to the
perceived urgency of taking action. The need for innovation tends
to be less evident before disasters and after the immediate crisis
period, which tends to result in greater disagreement about needs,
possibilities, actions and consequences [48]. Consequently, emer-
gent volunteerism is likely to occur in response to and in the
immediate aftermath of emergencies and disasters, particularly
when citizens believe that the needs of those affected are not
being met by formal response organisations. An earlier study of
emergence found that most groups lasted for only short periods of
time, usually hours or days [83]. However, some groups may
remain active over longer periods and some may develop into
established organisations. Atsumi and Goltz [4], for instance, de-
scribe how some volunteers with experiences in the Kobe earth-
quake remained active in other disaster events, and how the
Nippon Volunteer Network Active in Disaster (NVOAD) transi-
tioned from an emergent to an established organisation following
the Kobe earthquake.
Emergent volunteers often have ‘real time’,‘on-the-ground’
views of the issues and problems people face, and can configure
themselves and their responses to meet local needs. Unlike
emergency services and other formal response organisations, they
are rarely constrained by pre-established rules, strategies and
technologies that may inhibit effective local response [31]. A study
of the 1985 Mexico City earthquake found that the emergency
response period was dominated by the activities of emergent
organisations and involved a considerable amount of emergent
behaviour [24]. These behaviours and organisations developed due
to the lack of prior disaster planning and the challenges created by
the earthquake, which exceeded the emergency response cap-
abilities that were in place [71]. For example, in the absence of an
official search and rescue service, a group of youths began crawl-
ing into collapsed buildings to reach people trapped inside. They

Selected definitions of volunteerism.
In volunteerism research:
‘Volunteering means any activity in which time is given freely to benefit an-
other person, group or organisation’([93], p. 215).
‘Volunteerism has four important attributes…First, it is a planned action;
people think and weigh their options before they make the decision to vo-
lunteer…Second, volunteerism is a long-term behaviour; most people who
volunteer continue this activity for an extended period of time…Third…
volunteering involves ‘non-obligated’helping…[and fourth] it occurs within
an organisational context’([63], p. 646).
‘Volunteerism refers to freely chosen and deliberate helping activities that
extend over time, are engaged in without expectation of reward or other
compensation and often through formal organisations, and that are per-
formed on behalf of causes or individuals who desire assistance' ([82], p. 3).
In the emergency/disaster context:
‘Volunteerism will be regarded as any act that is orientated to the direct or
indirect service of some other person or thing regardless of whether or not
such act serves the self-interest of the actor’([78], p. 1).
‘Volunteerism is thus defined as any monetarily uncompensated, wilful action,
be it spontaneous or organized, oriented toward the protection and/or re-
storation of symbols, interests, people, or other high priority values of a
personal or group nature’([96], p. 35).
‘A volunteer is any individual accepted to perform services by the lead agency
(which has authority to accept volunteer services) when the individual per-
forms services without promise, expectation, or receipt of compensation for
the services performed’[29].
A‘volunteer emergency worker…engages in emergency activity at the request
(either directly or indirectly) with the express of implied consent of the Chief
Executive (however designated), or of a person acting with the authority of
the Chief Executive of an agency wihich either the State emergency response
or recovery plan applies’([26], p. 114).
‘Potential spontaneous volunteers are individuals or groups of people who seek
or are invited to contribute their assistance during and/or after an event, who
are unaffiliated with any part of the existing official emergency management
response and recovery system and may or may not have relevant training,
skills or experience' ([7], p. 5).
‘Unaffiliated volunteers, also known as spontaneous volunteers, are individuals
who offer to help or self-deploy to assist in emergency situations without
fully coordinating their activities. They are considered ‘unaffiliated’in that
they are not part of a disaster relief organisation. Although unaffiliated vo-
lunteers can be significant resources, verifying their training or credentials
and matching them with the appropriate services can be difficult’[28].

rescued hundreds of people, despite having no prior training, ex-
perience or equipment. The group, ‘Topos de Tlatelolco’, became
formally organised in 1986 and has become a highly specialised
and trained search and rescue organisation. The organisation,
which remains independent but coordinates its activities with
government agencies and other organisations, sent search and
rescue teams to assist in responses to the 2009 L′Aquila earth-
quake in Italy and the 2010 Haiti earthquake [13].
More recently, the Student Volunteer Army formed to help
clean up liquefaction following the 2010–2011 earthquake se-
quence in Christchurch, New Zealand [88]. Thousands of students
joined the efforts, which also involved volunteers from farming
communities known as the ‘Farmy Army’, which were widely
publicised via social media. Volunteers expended an estimated $1
million worth of labour within the first week and around 75,000 h
over the course of their effort [88]. Similarly, BlazeAid formed in
the aftermath of the 2009 ‘Black Saturday’bushfires in Victoria,
Australia, to help farmers rebuild fences. The group was formed by
two farmers who sought assistance from family, friends and local
volunteers to clear debris and rebuild farm fences [91]. After re-
building the fences within a week, they began to help others and
the organisation was formed. BlazeAid invites people to volunteer
for as little or as long as they like, holds Volunteer Workers in-
surance, and has a Code of Conduct that outlines the organisation's
expectations in terms of health and safety, use and care of
equipment, and volunteers' interactions with each other and re-
cipients of help. The organisation has received considerable media
coverage, political support and sponsorship from mostly private
sector organisations and has expanded its activities to assist peo-
ple affected by flood, cyclone and drought throughout Australia.
It is important to recognise that most emergent volunteerism is
less visible and does not lead to ongoing, formal organisation. For
example, Webber and Jones [91] note that ‘informal volunteering’
was common after the ‘Black Saturday’bushfires, with local people
helping those affected to shoot injured livestock, clear fallen trees,
connect generators and build fences. Similarly, Smith et al. [81]
describe the critical role played by ordinary Haitians who trans-
lated their language and culture to assist in the implementation of
a disaster triage system following the 2010 earthquake. Moreover,
as discussed earlier, different cultural understandings may mean
that helping activities are not recognised as volunteering at all
[72]. The potential benefits of utilising indigenous and other forms
of local knowledge in emergency and disaster management are
now widely recognised (e.g. [53,54,46,39]). For example, a study of
the 2011 Rena oil spill in Maketū, New Zealand, attributed the
success of the clean-up to Māori cultural values and knowledge,
which local people often had to assert in the face of outside
‘experts’who wanted to advise them ([80], p. 9).
Fernandez et al. [31] identify two main risks associated with
spontaneous volunteers. The first involves the failure of emer-
gency managers to effectively utilise volunteers, which creates
potential for loss of life and injury, property damage and poor
public perception of emergency/disaster response. The second is
associated with the actions of untrained, uncoordinated volun-
teers, who may disrupt organised responses and reduce the re-
sources available to those affected. For example, following the
1999 Golcuk earthquake in Turkey, which killed 17,000 people,
emergency services’attempts to access the disaster area were
hindered by a 32 km traffic jam caused by spontaneous volunteers
[41]. There is also a risk that the actions of untrained and un-
coordinated volunteers will cause harm to survivors, emergency
responders, and volunteers themselves. Although untrained
citizens saved around 800 victims in the 1985 Mexico City
Earthquake, 100 rescuers died trying to save others [41]. Similarly,
a lack of information about the toxicity and harmful effects of
petroleum after the 2007 Hebei Spirit oil spill in South Korea
meant that many volunteers were not properly clothed and later
suffered from skin diseases [44]. Risks to both safety and organi-
sational responses were apparent following the 2001 terrorist at-
tacks on the World Trade Center, which saw around 30,000 vo-
lunteers converge on New York City. Many of the initial volunteers
who arrived at the scene to assist search and rescue operations
were overwhelmed by the emotional impact of their activ-
ities. Liath ([51], p. 17) notes that without proper training and
support, ‘these volunteers can in turn become traumatised, and by
becoming victims of the disaster, may require the very services
that they sought to provide’.
4.2. Extending volunteerism
Groups and organisations without emergency or disaster
functions often extend their activities to volunteer in times of
crisis. These volunteers are usually part of an existing community
group such as a chamber of commerce, sporting club, religious
group or service organisation. Like emergent volunteers who act
as individuals or form a new group, these volunteers often have
intimate understandings of local needs and can draw on existing
networks and resources to meet them. In rural Australia, volun-
teers from organisations such as the Country Women's Association
and Rotary International often play critical roles in relief and re-
covery by collecting and distributing donated food, clothing and
other domestic goods. Sporting and recreational clubs may also
play significant roles. For example, Four Wheel Drive clubs from
across Victoria banded together to assist people who were affected
by the 2009 Black Saturday bushfires. Demonstrating a high de-
gree of cooperation and coordination, the clubs worked together
to deliver caravans to families who had lost their homes, helped
clear debris and damaged trees, re-fenced properties, delivered
hay to farmers and ran supplies to volunteer fire brigades
[89,3,92].
Corporate involvement in disaster response is becoming in-
creasingly common as part of corporate social responsibility (CSR)
[84]. Although research has largely focused on the role of dona-
tions [45,57,58,97], some studies have considered the role of
corporate volunteers after disaster. Twigg [84] notes that many
companies do not simply want to donate money in the aftermath
of disaster and instead seek more active involvement. Many also
recognise the changing expectations of employees, who seek more
than monetary reward. Choong [14], for example, examined DHL
Asia-Pacific (a global logistics company) employees' participation
in a disaster response programme following the 2004 Indian
Ocean Tsunami. Employees collected donations and helped to
transport and deliver supplies to Tsunami affected areas. Company
vehicles were used to transport tourists to safety in Phuket,
Thailand, and volunteers were deployed to an Airport Emergency
Team (an initiative of the World Economic Forum) in Colombo, Sri
Lanka, to assist in the distribution of over 7000 t of relief supplies.
The study found that CSR strategies are more likely to benefit from
strong employee participation when activities are aligned with
their corporate identity. DHL had the skills and resources to
provide logistical support following the disaster, and empowered
local managers and employees to determine their level of com-
mitment. The company's involvement in disaster preparedness
and response was formalised by a public–private partnership be-
tween the United Nations Development Programme (UNDP), Of-
fice for the Coordination of Humanitarian Affairs (OCHA) and
Deutsche Post DHL [86]. Another example of corporate vo-
lunteerism facilitated through partnerships with a disaster relief
organisation is the ‘Ready When the Time Comes’programme
initiated by the American Red Cross and WW. Grainger Inc.
(an industrial supply company). Employees from businesses are
trained and mobilised by the Red Cross as a community-based
J. Whittaker et al. / International Journal of Disaster Risk Reduction 13 (2015) 358–368 363

volunteer force during disasters. In 2011 the programme had
14,000 trained volunteers from more than 460 businesses and
organisations in 54 cities [1]. The Red Cross promotes the pro-
gramme as a way for companies to become involved in their
communities, develop their employees’skills, and align with one
of the most respected organisations in the USA.
4.3. Digital volunteerism: a new mode
The increasing accessibility of sophisticated yet simple in-
formation and communication technologies has enabled citizens
to participate in emergency and disaster management in new
ways. In particular, widespread use of social media and web-based
mapping software has allowed citizens to freely produce and
disseminate their own emergency-related information. Examples
range from basic use of sites like Facebook to share information
through to more complex uses involving data mining and crisis
mapping. For example, the ‘Pictures and documents found after
the April 27, 2011 Tornadoes’Facebook page was set up after a
resident of Lester, Alabama, found photos in her yard following the
storm. She created the page to enable people to announce if they
had lost or found an important item. In the year that the page was
operational, around 2000 items were returned to their owners
[37]. The page was also used by scientists who examined 934
debris reports for which a clear point of origin and landing could
be determined. The study found that objects lofted by tornadoes
can travel further than previously thought, with light items tra-
velling as far as 220 miles (354 km) from their point of origin [50].
Meier [55] describes how graduate students at Tufts University
in Massachusetts launched a live crisis map within hours of the
2010 Haiti earthquake to document the extent of the damage and
the affected population′s urgent needs. Information was initially
sourced from social media such as Twitter and some mainstream
media. However, extensive live coverage of the disaster meant that
students soon began crowdsourcing data from several hundred
online sources. Hundreds of volunteers from the USA and abroad
volunteered to process the data, with the group manually triaging
and geo-referencing more than 1,500 reports using the Ushahidi
platform (free, open source mapping software). After a few days a
SMS short code was set up and integrated with the Ushahidi
platform, enabling Haitian people to text in their location and
specific needs. With the majority of SMS messages written in
Haitian Creole, social media was used to recruit volunteers from
the Haitian diaspora who translated around 10,000 messages over
the course of the operation. The success of the operation led to the
creation of the Standby Task Force, a network of over 1000 vo-
lunteers in 80 countries, as well as many other crisis mapping
organisations and initiatives [55].
Advances in information and communication technologies
have not just enabled mass information dissemination, but
also information and knowledge production [52]. Volunteered
geographic information (VGI) ‘…involves the sharing and map-
ping of spatial data…through voluntary information gathered by
the general public’([38], p. 237). The strength of VGI lies in the
notion that information obtained from a group of many observers
is likely to be more accurate than that obtained from a single
observer. Goodchild and Glennon ([35] p. 235) note that despite
concerns about the quality of data produced by ‘non-experts’free
of institutional and legal frameworks, ‘the quality of VGI can ap-
proach and even exceed that of authoritative sources’. The rich,
contextual information that ‘on-the-ground’observers can
provide, and the speed with which it can be updated, are key
advantages. Nevertheless, there are a number of challenges asso-
ciated with use of VGI in emergency management. Because it
cannot be known beforehand how much information will be vo-
lunteered and where it will come from, VGI should be treated as a
supplementary source of information only. Nor can the quality of
data cannot be guaranteed, with the potential for citizens to in-
tentionally or unintentionally contribute erroneous information.
Citizens may also be biased toward exceptionally large or severe
events, meaning that smaller events go unreported [66].
Digital volunteerism is likely to become increasingly prevalent
in emergency and disaster management worldwide. A key
strength of the crowdsourcing approach is that volunteers do not
necessarily have to invest long periods of time to participate, nor
do they need to be near the emergency or disaster affected area.
The rise of digital volunteerism also means that citizens may
participate in emergency and disaster management in other
countries.
5. Implications for emergency and disaster management
This paper has examined some of the ways citizens participate
in emergency and disaster management informally by volunteer-
ing their time, knowledge, skills and resources to help others.
Research suggests that citizen convergence on emergency and
disaster sites is inevitable, so emergency services and other or-
ganisations must plan for and manage the participation of these
volunteers. This is necessary to reduce the risk that untrained and
uncoordinated volunteers will disrupt organised response and
reduce the resources available to those who are affected. However,
it is also necessary to maximise the effectiveness of emergency
and disaster management by drawing on the immense knowledge,
skills, resources, networks and enthusiasm of ordinary citizens.
Governments and agencies worldwide are increasingly re-
cognising the opportunities and challenges posed by informal
volunteers. Indeed many have developed strategies and resources
for engaging and managing them. However, organisational culture,
risks and liabilities remain significant barriers to greater involve-
ment of informal volunteers in emergency and disaster
management.
5.1. Cultures of emergency and disaster management
The extent to which citizens are able to participate in emergency
and disaster management depends largely on formal institutional
structures and arrangements. Most developed countries employ
bureaucratic, command-and-control approaches that originate in
the paramilitary roots of emergency and disaster management
[59,69]. Command-and-control approaches tend to assume a clear
distinction between the pre-emergency and emergency period,
with the former characterised by a sense of normalcy and the latter
by chaos and disorganisation. Conceived in this way, the role of
emergency and disaster organisations is to establish command over
chaos and regain control over disorganisation [23]. However,
Quarantelli [70] notes that command-and-control rarely works
well, even in military combat situations, casting doubt on its
applicability and effectiveness in civilian contexts.
Drabek and McEntire [21] identify a range of assumptions
that underpin command-and-control approaches: bureaucratic
response occurs in a vacuum; information outside of official
channels is lacking or inaccurate; standard operating procedures
will always function in disasters; departures from bureaucratic
guidelines are detrimental; citizens are inept, passive or non-
participants in disaster operations; and ad hoc emergence is
counterproductive. As noted above, disaster research challenges
many of these assumptions. It demonstrates that citizens tend to
become more cohesive and engage in pro-social behaviour in
disaster situations. These findings are the starting point for an
alternative approach to emergency and disaster management that
involves ‘loosening rather than tightening up the command
J. Whittaker et al. / International Journal of Disaster Risk Reduction 13 (2015) 358–368364

structure’([70], p. 381). Emergencies are instead viewed as ‘a set
of problems which have to be solved with some degree of speed
and effectiveness by the existing resources within that social unit
–the community’([23], p. 156). Dynes argues that this problem-
solving model rests on a more realistic set of assumptions and
principles, derived from empirical research: emergencies do not
reduce the capacities of individuals and social structures to cope,
but rather present new challenges; existing social structure is the
most effective way to address these challenges; social units are
resources for problem solving, rather than problems in them-
selves; and, emergencies are characterised by decentralised and
pluralistic decision-making, so autonomy of decision-making
should be valued over centralisation of authority. Thus Dynes
([23], p. 149) maintains that an ‘open system’is required ‘in which
the premium is placed on flexibility and initiative among the
various social units…and those efforts are coordinated. The goals
should be oriented toward problem solving, rather than avoiding
chaos’.
The problem solving and command-and-control models
broadly align with what Harrald ([36], p. 256) terms ‘agility’
(creativity, improvisation, adaptability) and ‘discipline’(structure,
doctrine, process). A degree of discipline is necessary for large
organisations to be mobilised and managed; yet agility is needed
to ensure broad coordination and communication. Discipline is
also needed to ensure the rapid and efficient delivery of services
under extreme conditions, while agility is necessary to enable
creativity, improvisation and adaptability in the face of un-
certainty. Structure and process are needed to ensure the technical
and organisational interoperability of emergency and disaster
management organisations; however, they must also be flexible
enough to interact with and utilise the many spontaneous vo-
lunteers and emergent organisations that want to help [36]. This is
supported by Boin and t’Hart ([10], p. 366), who argue that
‘the circle of organisations actively involved in crisis response
networks is [often] drawn too narrowly’, focusing largely on es-
tablished and expanding organisations, with limited participation
of extending and emergent organisations.
Stallings and Quarantelli [83] offer five key principles for
emergency managers when engaging with emergent groups that
are also applicable for managing relationships between emergency
managers and informal volunteers. First, they emphasise that
emergence is inevitable before, during and after disasters because
citizens will identify needs that are not being met by emergency or
other agencies. These needs may be perceived or real; regardless,
emergence is likely to occur. Second, they stress that although
emergency agencies may harbour concerns about emergent
groups’informal structures, it should be recognised that ‘their
looseness is one of [their] real strengths’([83], p. 98). The informal
nature of emergent groups means that their efforts to undertake
new tasks are not constrained by established procedures, rules or
legislation. Third, emergent groups are not always functional, nor
are they always dysfunctional. Emergent groups may not be the
ideal way to address a particular problem; nevertheless, citizen
attempts at resolution should be valued, and it should be ac-
knowledged that there are always alternative approaches. Fourth,
it is important to recognise that although groups may emerge due
to perceived failings or needs that are not being met by agencies,
citizen groups are not always in opposition to public authorities. It
is important for emergency managers to engage with these groups
positively, and not to assume opposition. Finally, Stallings and
Quarantelli insist that emergent phenomena cannot be eliminated
through prior planning. Instead, emergency managers should
consider what forms of emergent behaviour and groups they
might want to facilitate, for example by encouraging existing ci-
tizen groups to take on an emergency capability or specific tasks in
an emergency.
Some government agencies are quite advanced in their in-
tegration of official and unofficial emergency response. Scanlon
et al. [77] document the policies and procedures implemented by
the Amstelland Safety Region in the Netherlands to make better
use of ordinary people's knowledge, skills and capacities in
emergency management. Criteria were established to help emer-
gency responders decide whether and how to cooperate with or-
dinary citizens, existing organisations and emergent groups. The
policies explicitly allow emergency responders to accept assis-
tance from ordinary citizens and organisations, provided that:
participation is voluntary; the tasks assigned have minimal safety
risks; the tasks add value to the overall emergency response; and
citizens only fulfil a task when they have the skills and knowledge
to complete the task successfully. This more integrated model of
emergency management requires official emergency responders
to merge with existing social structures and not attempt to re-
organise groups and their activities. Official responders are
expected to legitimate volunteer activity by enabling access to the
affected area, by providing special clothing so that volunteers can
be recognised, and by keeping volunteers informed about emer-
gency work. Emergency responders are also expected to identify
the ‘natural leaders’within volunteer groups and work with them,
for example by inviting them to participate in meetings about the
progress of the emergency response. These initiatives are built into
five planned phases beginning with victims and bystanders ar-
riving on the scene, and ending with official acknowledgement of
volunteer efforts and possible provision of counselling and com-
pensation [77].
Implementation of such initiatives may be more complicated
in situations where emergency responders are unable to assess
whether citizens have the necessary knowledge and skills to make
a worthwhile contribution. They may also be unwilling to accept
assistance for fear of being held responsible if a volunteer is
harmed.
5.2. Safety and liability
Sauer et al. [76] note that despite the ‘universal presence’of
spontaneous volunteers following disasters, few studies have
considered related issues of safety and liability. Informal volun-
teers may risk physical or psychological harm to themselves and
others if they engage in activities without necessary knowledge,
skills, equipment and training. A survey of 19 organisations iden-
tified through the US National Voluntary Organisations Active in
Disasters (NVOAD) found that 15 (79%) had encountered sponta-
neous volunteers during their response activities. 18 (95%) orga-
nisations reported that they did not perform background cheques
on spontaneous volunteers, with just 10 (53%) providing just-
in-time training. Two organisations reported a spontaneous
volunteer death, while eight reported injuries to volunteers. One
organisation had been sued by a spontaneous volunteer and three
had been sued due to the actions of a spontaneous volunteer. Only
six organisations (32%) believed they were liable for spontaneous
volunteers’actions [76].
Orloff [62] identifies two main liability risks for emergency
management agencies arising from the participation of sponta-
neous volunteers. The first is that volunteers or their families will
sue agencies for death, injury or damages incurred as a result of
volunteer activities, and the second is that recipients of help will
sue agencies for the unintended or intended consequences of vo-
lunteers’actions. In the USA, confusion about liability stems from
complicated laws, inconsistent protections from state to state, and
the often multiple affiliations of volunteers that blurs lines of
responsibility for protection [62]. Eburn [25] discusses legislation
introduced in a number of Australian States to limit the liability
of ‘Good Samaritans’and voluntary members of community
J. Whittaker et al. / International Journal of Disaster Risk Reduction 13 (2015) 358–368 365

organisations. These Acts are primarily intended to protect those
who respond to medical emergencies where life is threatened, for
example by providing first aid or medical care. Importantly, the
Acts do not apply to Good Samaritans who act to protect property.
Those who provide emergency assistance must act in good faith
(i.e. their intention must be to assist the person concerned) and
without the expectation of payment or other reward. Although
most of the Acts intend to protect volunteers from personal lia-
bility, the organisation for which they are volunteering may still be
liable [25]. Nevertheless, in her study of spontaneous volunteer
management in Victoria, Australia, Saaroni [74] identified very
little evidence of governments being sued for the actions of
spontaneous volunteers and noted that litigation against volun-
teers is uncommon.
While further research into legal liability and volunteer safety
is needed, the risks associated with informal volunteerism can be
minimised. Hospitals routinely manage risks associated with the
use of volunteer health professionals during emergencies through
prior planning and training to meet surge capacity, and through
strict credentialing procedures [42]. Safety can be increased and
liability risks reduced through registering, training, credentialing,
assigning appropriate tasks, and supervising volunteers [76].
However, such measures are unlikely to be effective where vo-
lunteerism is more informal and emergent. emergency managers
must therefore be attuned to what is happening on the ground
and be prepared to engage with a diverse range of volunteers.
It is important to recognise that capacities for managing in-
formal volunteers may be limited in countries and regions where
government and other institutions are weak or absent. Laws to
protect the health and safety of volunteers and recipients of help
may also be limited. This was evident in the aftermath of the 2010
Haiti earthquake when a group of ten Baptist missionaries from
Idaho in the USA was apprehended attempting to cross the Haiti-
Dominican Republic border with 33 children aged two to twelve
[5]. The group was part of the New Life Children′s Refuge ([60],
p. 3), an organisation ‘dedicated to rescuing, loving and caring for
orphaned, abandoned and impoverished Haitian and Dominican
children…[and providing] opportunities for adoption into a loving
Christian family’. It was later revealed that many of the children
were not abandoned or orphaned. Questions were raised about the
intentions of the group, whose leader was experiencing financial
difficulty and may have been seeking monetary rewards associated
with placing children in adoptive homes. It was also revealed that
one of the group′s legal advisors was under investigation for al-
leged connection with sex trafficking in El Salvador [40]. Although
uncommon, examples such as this highlight the need to develop
capacities and procedures for monitoring and managing the con-
tributions of informal volunteers during emergencies and
disasters.
6. Conclusion: co-producing emergency and disaster
management
Ordinary citizens who volunteer their time, knowledge, skills
and resources to help others in times of crisis represent an im-
mense resource for emergency and disaster management. Re-
search reviewed in this paper suggests that unsolicited volunteers
will be active in times of crisis, so it is vital that emergency ser-
vices and other organisations are prepared to cooperate with them
and coordinate their activities. This is necessary to ensure effective
responses and avoid duplication of effort, but also to prevent vo-
lunteers from being put in situations where they may harm
themselves or others.
There are many examples of governments, businesses and or-
ganisations across the world that are cooperating and coordinating
their activities with informal volunteers. This has typically in-
volved developing volunteer registers and training programmes
prior to an event. Yet such measures are unlikely to be effective
where volunteerism is highly informal and emergent. It is there-
fore important that emergency managers are attune to what is
happening on the ground and are prepared to engage with a di-
verse range of volunteers. Attempts to ‘integrate’informal volun-
teers into formal systems may prove counterproductive by
quashing the adaptability, innovativeness and responsiveness that
informal volunteers bring to emergency and disaster management.
Further research is needed to examine how organisational cultures
and structures are changing to account for informal volunteerism,
and how associated legal liabilities and safety concerns are being
managed. Such research is vital if we are to develop more adaptive
and inclusive models of emergency and disaster management that
harness the capacities and resiliencies that exist within and across
communities.
