The Impact of Armed Conflict on Civilians: A Human Security Perspective

When we picture war, we tend to imagine soldiers, tanks, and front lines. The reality of modern conflict is very different. Today, the people most likely to be killed, injured, uprooted, or exploited in armed conflict are not soldiers at all, but ordinary people who never chose to fight. Farmers, students, nurses, shopkeepers, and children now sit at the centre of violence that was once confined to distant battlefields. This shift sits at the heart of the human security approach, which insists that genuine security is measured not by the strength of armies but by the safety and dignity of individuals. Understanding why civilians have become both the primary victims and a central feature of contemporary war is essential to understanding the global state of human security.

Who counts as a civilian 🔗

In legal terms, a civilian is anyone who is not a member of the armed forces and is not taking part in the fighting. International humanitarian law builds an entire protective framework around this definition. Under the Additional Protocol I to the Geneva Conventions, deliberately directing attacks against civilians who are not participating in hostilities is treated as a war crime under the Rome Statute of the International Criminal Court.

This protection rests on a single guiding idea known as the principle of distinction. Parties to a conflict must always distinguish between combatants, who may be targeted, and civilians, who may not. The Center for Civilians in Conflict describes the resulting norm of civilian immunity as the cornerstone of the laws of war. The catch is that this immunity is not unconditional: a civilian loses protection for as long as they directly participate in hostilities. That qualification, simple on paper, becomes extraordinarily difficult to apply in the messy reality of today’s wars.

The civilianization of conflict 🔗

Scholars use the term civilianization of armed conflict to describe a profound change in how wars are fought. The International Review of the Red Cross notes that civilians now play an increasingly important and complex role in conflict, appearing both as victims and, at times, as participants. Three overlapping trends explain this change.

First, the battlefield has moved into the home. Wars are no longer fought over isolated front lines but inside crowded towns and cities, which means civilians are physically present wherever fighting occurs. Second, many of those doing the fighting are no longer uniformed soldiers but members of non-state armed groups who hold no formal combatant status, which blurs the very line that the principle of distinction depends on. Third, civilians are increasingly drawn into the conflict itself, providing food, shelter, transport, information, or recruits, sometimes willingly and sometimes under coercion.

Why civilians become targets 🔗

This blurring is not accidental. For many armed groups, civilians have become strategic objectives rather than people to be spared. Controlling a population can deliver legitimacy, resources, and human shields. Civilians are also attacked to spread terror, to punish communities perceived to support the enemy, or to drive entire ethnic or religious groups out of a territory. When this targeting is systematic, it can amount to ethnic cleansing or crimes against humanity. The result is that violence against non-combatants is frequently a deliberate tactic, not merely an unfortunate side effect of war.

The human cost 🔗

The consequences of this shift are staggering, and they extend far beyond death on the battlefield.

Civilian casualties 🔗

Civilians now make up the overwhelming majority of war casualties. At the United Nations, speakers have stressed that around ninety per cent of wartime casualties are civilians, with that share rising sharply when explosive weapons are used in populated areas. The scale of harm has been worsening rather than improving. The UN recorded more than 33,000 civilian deaths in armed conflict in 2023, a jump of seventy-two per cent over the previous year, across conflicts stretching from Gaza and Sudan to Myanmar, the Sahel, and Ukraine.

The harm also reaches well beyond direct violence. Bombing and shelling routinely destroy the infrastructure that ordinary life depends on. Attacks damage water systems, power plants, hospitals, and schools, cutting people off from healthcare, sanitation, and education long after the fighting moves on. Landmines and explosive remnants of war keep killing civilians and block access to farmland for years.

Displacement and refugee flows 🔗

For many people, the only way to survive is to flee, and displacement has now reached record levels. The number of people forcibly displaced worldwide passed 123 million by the end of 2024, with children accounting for around forty per cent of that total. These figures include two distinct groups: refugees, who cross an international border in search of safety, and internally displaced persons, who flee their homes but remain inside their own country.

Displacement is not an escape from danger so much as a different form of it. Uprooted families face renewed violence, loss of livelihoods, and severe shortages of food, water, and shelter. Refugee flows also carry conflict across borders, straining neighbouring states and turning what might look like an internal crisis into a regional and global concern. This is one of the clearest reasons why human security treats civilian protection as an international responsibility rather than a purely domestic matter.

Exploitation and gross violations 🔗

Beyond death and displacement lies a wide spectrum of exploitation. Sexual and gender-based violence is used as a weapon to terrorise and humiliate communities. Children are recruited into armed groups, often after their schools are attacked or destroyed, as the UN has documented in places such as Afghanistan and Ethiopia. Medical workers and facilities are deliberately targeted, with the UN recording thousands of incidents of violence against healthcare in a single year. Persons with disabilities and the elderly, unable to flee, are sometimes killed where they stand. These are not isolated abuses; taken together, they represent gross and systematic violations of humanitarian law.

The human security lens 🔗

Why frame all of this through human security rather than traditional national security? The difference lies in who is being protected. Traditional security focuses on the state, its borders, and its military strength. Human security shifts the unit of analysis to the individual, asking whether real people are free from fear and free from want.

Through this lens, a country can possess a powerful army and secure borders while its citizens remain deeply insecure, hungry, displaced, or terrorised. A civilian fleeing shellfire, a child pulled out of school to carry weapons, and a family without clean water after a strike on a treatment plant are all human security failures, even if the state itself is not under threat of invasion. This perspective explains why protecting civilians has moved from the margins of war to the centre of contemporary debates about security.

International law and the duty to protect 🔗

The international community has built a substantial body of rules to limit civilian suffering. The four Geneva Conventions of 1949 and their Additional Protocols form the backbone of international humanitarian law, setting out who must be protected and how. War crimes, crimes against humanity, ethnic cleansing, and genocide are all defined and, in principle, punishable. Yet rules only matter when they are respected, and the persistent gap between the law on paper and conduct on the ground is precisely what the human security approach seeks to close.

The responsibility to protect 🔗

One of the most significant responses to this gap is the Responsibility to Protect, often shortened to R2P. Emerging from the failures of the international community to halt mass atrocities in Rwanda and the former Yugoslavia during the 1990s, the doctrine was unanimously adopted at the 2005 UN World Summit. It rests on three pillars: every state has the primary responsibility to protect its own population from genocide, war crimes, ethnic cleansing, and crimes against humanity; the international community should help states meet that responsibility; and where a state manifestly fails, the international community should respond collectively, with the use of force considered only as a last resort.

R2P reframes sovereignty itself. As analysts at the Brookings Institution explain, the doctrine draws on the idea of sovereignty as responsibility, meaning that the right to govern carries a duty to protect. This is also why internal conflicts can no longer be dismissed as no one else’s business. The UNHCR has noted that protection needs, rather than borders, increasingly define when the international community ought to act. At the same time, R2P remains contested, with critics arguing that intervention is applied selectively and can be used as a pretext for political or military aims.

The protection of civilians in the wider region 🔗

These questions are far from abstract here. As a country that has hosted large numbers of refugees from neighbouring conflicts and experienced internal displacement of its own, the issues of civilian protection, humanitarian law, and managed refugee flows are immediate policy concerns rather than distant ones. At the United Nations, representatives have repeatedly highlighted the severe humanitarian consequences of armed conflict and stressed that the primary responsibility for the safety of populations rests with national governments, while recognising the role of the wider international system when those governments cannot cope. Balancing respect for sovereignty with a commitment to protecting people is one of the central foreign-policy tensions of the present era.

Bringing it together 🔗

The targeting of civilians is not a temporary feature of a few brutal wars; it is a defining characteristic of modern conflict. As fighting moves into cities, as the line between soldier and citizen dissolves, and as displacement reaches historic levels, the protection of non-combatants has become one of the most urgent challenges in the study of human security. Laws like the Geneva Conventions and doctrines like the Responsibility to Protect provide a framework, but they depend on political will to mean anything at all. True security, the human security approach reminds us, cannot be achieved through military strength alone. It requires placing the safety and dignity of ordinary people at the very centre of how we think about war and peace.

What do you think? If a state is clearly failing to protect its own civilians, where should the line be drawn between respecting national sovereignty and intervening to protect human lives? And if civilians now bear ninety per cent of the cost of war, should the way we measure a nation’s security shift from the strength of its military to the safety of its people?
