    Where civil blood makes civil hands unclean.—Shakespeare, Romeo and Juliet, 1597

    Complex emergencies today represent the ultimate pathway of state disruption Zwi says that recent conflicts such as those in northern Iraq, Somalia, Rwanda, Angola, the former Yugoslavia, and the province of Kosovo should be interpreted as complex political disasters where “the capacity to sustain livelihood and life is threatened primarily by political factors, and in particular, by high levels of violence.”1 Although each of the over 38 major conflicts that have occurred in this decade since the end of the cold war is unique, all share similar characteristics (box). Most blatant is that they represent catastrophic public health emergencies in which over 70% of the victims are civilians, primarily children and adolescents

    These mainly internal crises are popularly referred to as complex emergencies. The complexity refers to the multifacted responses initiated by the international community and further complicated by the lack of protection normally afforded by international treaties, covenants, and the United Nations Charter during conventional wars.

    Characteristics of complex emergencies

    • Administrative, economic, and political social decay and collapse

    • High levels of violence

    • Cultures, ethnic groups, religious groups at risk of extinction

    • Catastrophic public health emergencies

    • Vulnerable populations at greatest risk

    • Primarily internal wars with major violations of Geneva Conventions and Universal Declaration of Human Rights

    • Increased competition for resources between conflicting groups

    • Increased migration as refugees or internally displaced populations

    • Long lasting and widespread

    Health resources, both civilian (those provided by United Nations agencies, the International Committee and Federation of the Red Cross/Red Crescent, and many non-governmental organisations) and military, have played a major part in the emergency response, recovery, and rehabilitation phases of complex emergencies. In the process health providers have made major advances in assessment, management, education, training, and research,25 and they remain among the few existing political consciences still available for vulnerable populations worldwide. To be both successful and safe in complex emergencies, health providers need to expand their knowledge base to include issues of integrated management, transportation, logistics, communication, negotiation and mediation, security, and international humanitarian law.

    Complex emergencies will continue to threaten the health of nations. In this article I describe the various contributing factors, deficiencies, and needs most likely to precipitate future complex emergencies and outline the sorts of responses that will be needed to deal with them This article draws on research but also on analysis of the experience of international and non-governmental organisations in dealing with many of the complex emergencies of this decade.

    Summary points

    Complex emergencies represent the international response to state disruption and its sustaining infrastructure

    Understanding of complex emergencies has arisen from the many post cold war conflicts of the 1990s, though complex emergencies can be catalysed by natural and other disasters

    Complex emergencies need to be recognised for the public health disasters they are and for the public health expertise required by civil and military authorities

    Factors influencing future complex emergencies

    Complex emergencies existed during the cold war era, but the responses were limited or non-existent, primarily because of vetoes on action in the UN Security Council.6 They will probably continue as a post cold war phenomenon through the early part of the next decade, predominantly in Africa, Asia, and South and Central America. As existing governments collapse, militaries become increasingly supported by undisciplined paramilitaries, while insurgents and organised gangs and warlords gain power; the collapse is usually preceded by worsening corruption, criminalisation of government, and suspension of the rule of law, such as in Russia and Zaire. In disrupted states (a term first used by H Smith in unpublished paper, 1999), hospitals and clinics are the first to be destroyed and last to be rehabilitated.7 Indigenous healthcare providers become refugees early, and those who remain, as in Rwanda and Kosovo, are often targeted or intimidated if they defend the rights of patients.

    Small scale conflicts average 25-35 a year8 and will require cohesive sociopolitical and economic efforts to prevent them from developing into complex emergencies. By monitoring small scale disasters we can define the “public health” capacity and capability in many countries by exposing the vulnerabilities and inequities that typically lead to conflict situations.

    Major humanitarian emergencies caused by natural or technological disasters (35-60 per year and 15-25 per year, respectively)8 used to be considered conceptually separate from complex emergencies. But in weakened and disrupted states a natural disaster such as flood, famine, or deforestation or a major episode of industrial poisoning can expose the same vulnerabilities (box).

    Elements shared by all disasters in disrupted states

    • Disasters expose major public health deficiencies

    • Natural and technological disasters may catalyse a complex emergency

    • Lack of proper resources to respond

    • Lack of a security capacity

    • Lack of a management capacity

    • Politically favoured populations do better

    Political and legal factors

    An emerging view is that conflict related to ethnic issues is catalysed in disrupted states by the need of ethnic groups to fall back on what is considered safe and familiar.911 Territorial buffer zones that once separated ethnic groups disappear, causing increased competition for resources and migration of large populations, either as refugees who cross national boundaries or as internally displaced populations.

    With the onset of complex emergencies, ethnic based “ancient animosities” have been savage.12 Of the more than 6000 cultures that entered this decade some have disappeared through natural assimilation alone. State disruption, however, has placed many minority cultures at risk of extinction. The rate of extinction is so alarming that, if it continues, fewer than 600 cultures will remain by the year 2005.13 Also, the more removed the culture is from the developed world, the less interest and protection it generates.

    Culturally defined customs, skills, and arts passed along to succeeding generations include the foundations of health and public health refinements that allow a people to survive. When a culture is lost, so too is the inextricably connected professional and institutional memory of public health measures. Mitigation of public infrastructure and rehabilitation projects alone are not enough. This raises the question whether the loss of a culture, as a consequence of a complex emergency, should be addressed as a critical strategic, political, and security issue.

    Membership of the UN's General Assembly requires states to adhere to the Universal Declaration of Human Rights. Once the declaration is violated, several UN chapters allow the Security Council to bypass the sovereignty of the state where rights are being violated, in favour of non-permissive humanitarian intervention. Legally defining select complex emergencies as genocide requires, under international treaty, a sanctioned external force to enter the conflict and stop the slaughter. Political failure to do so (as in Rwanda and Cambodia) has caused a widening gap between claims of protection and actual outcome.

    Solutions to the problems of disrupted states will require greater international political decisiveness to overcome legal constraints. A first step is to give internally displaced populations the same legal protection as refugees. Success will then be judged by a reduction of the exceedingly high mortality rates of internally displaced people and their vulnerable populations—for example, unaccompanied minors.

    Socioeconomic factors

    Population increases have always been a threat to social stability. It is not the increase itself but the changing patterns of population that have the greatest potential for contributing to conflict. Both have major health implications Urban slums currently contain over half the poor people in the developing world, mostly women with children and inadequate support systems. The numbers of major cities with populations over one million are increasing, without a comparable growth in public health infrastructure such as sanitation, water supplies, and clinic services. Migration of populations for both environmental and economic reasons will dominate the next decade, especially in Asia, where resources per head are the least.

    Early in the 2010s urban populations in the developing world will exceed rural ones for the first time in history (figure). The need for humanitarian assistance is already moving from rural to urban areas. However, critical issues such as the defence of urban public health infrastructure, sanitation, and access to water are not being addressed in existing education, training, and research and management forums.

    Unfortunately, political and economic realities make some victims more deserving than others, suggesting that some weakened or disrupted states—those that are considered economically interdependent and geopolitically critical by developed governments—will be favoured as recipients for humanitarian assistance and disaster relief. The future requires a transparent humanitarian architecture and balance sheet of budgeted priorities and coordination of donor agencies that is internationally mandated and monitored. Health providers are uniquely qualified as lobbyists and advocates to diminish international fears of governmental self interest, hypocrisy, and racism in determining humanitarian priorities.

    Environmental security factors

    Major environmental and ecological abuses occur from deforestation, damming of waterways, human generated flooding and loss of topsoil, pollution, and the consequences of nuclear and chemical hazards. Environmental security is aimed at preventing “serious political and social instability stemming from human activities which reduce the environment's capacity to sustain life.”14 The term encompasses many of the public health issues inherent in complex emergencies, but on a larger scale with both national and regional ramifications. One can argue that there is a causal relation between the severe deforestation of the North Korean peninsula and environmental degradation, food and fuel scarcity, and smouldering conflict. Public identification of such environmental factors will demand that governments take action even though such action might lead to military involvement.

    Research issues

    Initial responses in the field to complex emergencies were understandably ad hoc. No foundation of applied health research exists for complex emergencies as it does for natural and technological disasters or for conventional crossborder wars. Major challenges were quickly identified in organisational management, refugee care, triage of victims, water and sanitation, nutrition, communicable diseases, and psychosocial, gender, and reproductive issues.

    Victims in developing countries have high mortality and morbidity from violent trauma, epidemics, starvation, and severe psychosocial disabilities. These public health consequences of refugee displacement and overcrowding affect all age groups, particularly infants and children under 5.15 16 Similar consequences are evident in the developed countries of Iraq, Yugoslavia, and Chechnya, where heightened trauma and the complications of undernourishment, dehydration, and untreated chronic diseases in infants and elderly people often dominate the clinical picture (R Brennan and BT Burkholder, unpublished data).

    The World Health Organisation and the Macfarlane Burnet Centre for Medical Research in Melbourne have begun to document studies that will build the foundation of research.16 One effect is that reports which first raised awareness of human rights and gender and reproductive issues are being transformed into operational programmes. Human rights abuses are now documented and a response coordinated, with early psychosocial and legal counselling offered by advocacy organisations. Gender specific health programmes have benefited from early assessment tools and standardised management protocols.17 18 Health providers must come to recognise that they often serve a wider humanitarian mitigation and prevention package that requires specialised education and training that supports protection, standardised documentation, and accountability for abuses.

    Lack of information sharing among major players in complex emergencies, and failed or incompatible communications systems, are important paralysing factors. Information technologies in Bosnia required high maintenance and overburdened staff resources but did not contribute to the overall efficiency of field operations. There is promise in field tested satellite telecommunications and image gathering, event monitoring and early warning database systems, and handheld computer links to organisational and research centres.19 A major challenge for information technologies is not only to aid efficiency but to serve as a tool for fostering collaboration between otherwise constrained vertical organisations.

    Public health responses

    Since the 1991 crisis in northern Iraq all decision makers (civilian and military) have been required to manage the “public health.” Failure to do so has been attributed partly to the inability of decision makers to consult and use public health consultants and advisers.20 The events of this decade show that public health no longer refers only to health and medical care but also encompasses transportation, communication, the judiciary, public safety, and all those disruptions in complex emergencies that must be corrected before a village, town, city, or nation can function (see box). This will further encourage the crossing of professional boundaries required for integrated assessments and information sharing and ensure the place of health professionals in the planning process. In current political-military implementation plans (for example, United States Presidential Decision Directive 56) normalisation of health indicators is considered the major measure of effectiveness, yet health professionals, other than those used to serve the forces themselves, are rarely considered in planning.

    Operational status of heath related programmes

    Operational and fully standardised programmes:

    • Water

    • Sanitation

    • Nutrition

    • Communicable diseases

    • Essential drugs

    • Individual programme assessments

    Programmes not fully standardised or institutionalised:

    • Reproductive health/women's issues

    • Human rights monitoring

    • Psychosocial or mental health

    • Codes of conduct

    • Education and training

    Not operational, or deficiencies exist:

    • Information technologies

    • Measures of effectiveness

    • Security

    • Information sharing

    • Civil-military collaboration

    • Coordinated logistics

    • Urban infrastructure

    • Urban humanitarian relief

    • Consequence management of nuclear, chemical, or biological events

    • Integrated assessments

    Lack of education and female illiteracy have traditionally topped the list of major factors contributing to overall child mortality and morbidity in the developing world. In this decade the moral integrity of governments and the presence of public health infrastructure (both absent in complex emergencies) have replaced these traditional public health indicators. This is especially true in some refugee camps, where no education occurs, girls and women have no rights and receive less than their fair share of food and commodities, and male children are recruited into the military. Refugee camps are anomalies of society. Steps must be taken to prevent their growth, except in support of emergency and short term humanitarian missions. The ability to prevent the establishment of long term camps will be a major measure of effectiveness.21

    Communicable diseases thrive in the overcrowded environment of camps, with unsanitary and disrupted infrastructures and the promiscuous defecation of children. Initially, health programmes in complex emergencies did not deal with tuberculosis in refugee camps. However, in camps the prevalence was found to be 4-6%, often with resistant forms—far beyond the alert rates for conventional communities. Dengue fever has emerged as a unique economic indicator of decaying urban infrastructure, prompting closer scrutiny by economists and public health authorities alike.22 Fears of the transnational spread of communicable diseases from camps and countries with poor public health are among the leading concerns of the developed world. The public in the developed world expects that relief programmes will not increase the risk to their lifestyles, so donors will in future demand attention to prevention, containment, and eradication of infectious agents.

    Security issues and the need for civil-military responses

    Wanton violations of the Geneva Conventions have included unprecedented and widespread rape; massacres; sniper targeting of children, adolescents, and pregnant women; attacks on feeding centre hospitals; diversion of food by warring factions; and attacks on relief workers (for example, 40 Red Cross workers have been killed in the past five years). Peacekeeping forces have also experienced casualty rates statistically higher than if a decisive force had been used.23 These violations are too often relegated to minor news stories and have failed to achieve the level of international concern and debate they deserve. The success of humanitarian assistance will depend on the ability of international organisations to reinstate and enforce these basic protections.

    Civil-military cooperation

    Peacekeeping forces, under chapter 6 of the UN Charter, have been restricted by ambivalent mission statements and weak rules of engagement, making them ineffective in past complex emergencies—for example, UNPROFOR in former Yugoslavia. Under chapter 7 of the UN Charter, peace enforcement operations, such as those in Haiti and Kosovo, separate warring factions or quell a conflict before a peace agreement is in place The requirements for humanitarian assistance may be at their peak during this phase. Future expectations are that the military and humanitarian relief organisations will train together as “field units” to ensure relief and security to populations during times of active conflict and heightened risk.24 Chapter 7 requires the coordination, monitoring, and enforcement of international humanitarian and human rights law, so health providers must understand that the role they play in documenting abuses under the law requires a degree of civil-military collaboration without compromise of agencies' autonomy.

    The future will probably provide more political clout to regional organisations, and regional peacekeeping battalions will develop under a more robust UN Standby Arrangements programme. Unfortunately, previous work done to optimise civil-military coordination was compromised in the initial intervention over Kosovo, which was run by NATO. NATO political decisions had the secondary effect of bypassing the humanitarian architecture already in place, specifically the UN Office of the Coordinator for Humanitarian Affairs and the early implementation of the UN High Commissioner for Refugees as the lead agency for humanitarian organisations.

    Managing the consequences of nuclear, chemical, and biological events, whether accidental or caused by terrorists, is beyond the capabilities of most countries. Coordination of the management of consequences requires a joint process that marries governmental decision makers, tactical level scientists, trained relief workers, and the military with self sufficient and tailored operational level task forces. To date only a few non-governmental organisations have shown interest in integrated education and training, and the international organisations' capabilities are lacking, especially in chemical and biological support.

    Factors contributing to future complex emergencies

    • Urbanisation of global populations

    • Urban dominance of world's poor

    • Failing public health infrastructures

    • Lack of moral integrity of governments

    • Availability of weapons and access to weapons of mass destruction

    • Economic inequities and corruption

    • Undisciplined military, paramilitary, and police

    • Suspension of rule of law

    • Wanton violations of protective treaties

    • Failures in environmental and ecological security

    • Food and water insecurity

    • Transmigration of populations due to conflict or political, economic, and environmental issues

    Conclusions

    The 1990s will be viewed as the decade of the emergence of the complex political disaster—but it is unlikely to see the end of them (box). Many people argue that the role of the international community and the effectiveness of humanitarian assistance have been seriously flawed. Even though health programmes have matured greatly, with professionalisation of providers, codes of conduct,25 and research and field based education programmes, health providers have been frustrated by meeting the challenge to save lives, only to find themselves sliding back again into crisis. Lessons gained through experience in recent complex emergencies will have ready application for future political trials and conflicts.
