Interacting new threats to human security: Closing the theory-evidence divide

Human security is a way of looking at the world that asks a simple but profound question: are people safe in their daily lives? For decades, experts often focused on whether nations were at war with one another. But in recent years, the definition has expanded to include the things that make a person feel unsafe regardless of borders: hunger, disease, economic collapse, and the fear of violence. Today, these dangers are no longer isolated events. They are tangled together, feeding off one another in a complex web. A pandemic can trigger an economic crisis, which in turn fuels political instability and crime. This interconnection means that solving one problem often requires understanding how it is linked to many others. The challenge for researchers is to map this tangled web without getting lost in the details, to see which threats are the most dangerous and how they are reshaping the globe.

Rogelio Madrueño, a researcher at the University of Bonn, tackled this challenge by treating the world not as a collection of separate countries, but as a single system of interacting risks. He wanted to move beyond studying issues like climate change or terrorism in isolation. Instead, he asked how these threats combine to create a specific kind of pressure on different parts of the world. To do this, he gathered data from 178 countries covering the years 2020 to 2024. He looked at a wide range of indicators, from the spread of infectious diseases and the readiness of governments to handle artificial intelligence, to levels of debt, inflation, and organized crime. By using a method that groups countries based on how similar their risk profiles are, rather than just their geography or wealth, he was able to reveal hidden patterns in how the world is changing.

The analysis revealed that the vast array of global dangers actually boils down to three main drivers. The first is a mix of biological and technological risks, where the spread of disease intersects with the rapid rise of artificial intelligence and cybersecurity threats. The second driver is traditional security, encompassing conflict, terrorism, and organized crime. The third is the macroeconomic pressure of high inflation and massive public debt. These three forces are not acting alone; they are deeply interconnected, creating a complex landscape where a shock in one area can ripple through the others. Madrueño's work suggests that the world is not just becoming more dangerous in a general sense, but is becoming more specialized in its vulnerabilities. Different groups of countries are facing distinct combinations of these threats, creating new zones of instability.

When the researcher sorted the countries into six distinct groups based on these risks, a clear picture of a shifting global order emerged. One group consists of nations facing extreme social fragility, where high exposure to terrorism and conflict is the dominant feature. Another group includes wealthy, advanced economies that, while structurally stable, are under persistent stress from crime, inequality, and the lingering effects of the pandemic. A third group is made up of vulnerable nations that are particularly threatened by the rapid pace of technological change and the spread of disease. There is also a small, highly stressed group of countries facing acute, multidimensional crises, including severe debt and political collapse.

Perhaps the most significant finding involves a large cluster of emerging powers. This group includes major economies and several new members of the BRICS alliance. These nations are not the poorest in the world, yet they face a unique and intense combination of threats. They are highly exposed to artificial intelligence risks, infectious diseases, inequality, and climate change, all while navigating complex geopolitical tensions. The data shows that these countries are increasingly moving into a distinct category, separate from both the traditional Western powers and the most fragile states. This suggests that the world is not simply moving toward a single global standard, but is fragmenting into different zones, each with its own specific set of challenges.

The study also challenges the idea that environmental and technological threats are the only things driving insecurity. While factors like climate change and new technologies are important, the research shows that security issues and economic pressures are equally critical. In fact, the most vulnerable countries are often those where these factors overlap. For example, nations that rely heavily on selling raw materials to the global market are often the same ones facing the highest levels of human insecurity. This creates a cycle where economic dependence makes it harder to cope with global threats, and those threats, in turn, make it harder to develop a stable economy.

Ultimately, the paper paints a picture of a world that is becoming more multipolar, meaning power is shifting away from a single dominant group to several competing blocs. One bloc is led by traditional Western powers, while the other is increasingly defined by emerging economies. These two groups are not just competing economically; they are facing different configurations of risk. The study suggests that this division is not just a political reality but a reflection of how different parts of the world are experiencing the pressures of the 21st century. The findings indicate that the old ways of thinking about security, which focused on borders and armies, are no longer enough. To protect human security in the future, the world will need to understand these new, complex patterns of vulnerability and recognize that the threats we face are shared, even if the ways they hit us are different.
