Modern conflict is rarely as simple as two armies clashing on a battlefield. In reality, crises today are fueled by cyber threats, resource scarcity, disinformation and more. For those interested in mastering peace and security principles, a security studies program equips practitioners to move from reactive crisis management to proactive, sustainable peacebuilding.
Peace and security studies is an interdisciplinary field that draws from political science, environmental studies, sociology, communication and psychology to transform conflict and foster peace at international, national and local levels.
While traditional national security studies focused on the military and the protection of states, modern security studies degree programs teach that true security must also safeguard people's lives and dignity.
Today, peacebuilders use four main pillars to analyze and navigate active conflict zones:
To understand how the above pillars translate from academic theory into life-saving action, let’s take a look at how modern peacebuilders have addressed crises on the ground.
For over 30 years, Somalia has grappled with fragmented governance and violent conflict. But the country also faces a massive environmental threat. Decades of severe drought and sudden floods have destroyed livelihoods, escalated fierce competition for natural resources and forced mass displacement.
In response, peacebuilders are using environmental security as a tool for stabilization. Somalia’s new Nationally Determined Contribution (NDC)—the country’s roadmap for climate mitigation and adaptation—goes far beyond a basic "do no harm" approach. Instead, it actively uses climate action to build social cohesion.
For example, in regions like Galmudug where water and grazing land are scarce, peacebuilders have established co-financed water infrastructure projects that require rival communities to jointly identify, design and fund shared priorities. By training local committees on sustainable environmental practices, practitioners create vital spaces for dialogue. These community-led dispute resolution systems address resource-based tensions and build trust long before frustrations can escalate into violence.
In Colombia between 1985 and 2018, over 450,000 people were killed (80% of whom were civilians), and nearly 8 million people were displaced by armed conflict between the state, paramilitary groups and guerrilla forces.
Following a historic 2016 Peace Agreement, a Truth Commission was established to document decades of atrocities. Over five years, investigators traveled across 23 countries to collect 15,000 testimonies from victims, indigenous communities and exiles. But gathering the truth was only half the battle; the other half was protecting it.
In a still-divided society, this massive archive of sensitive, classified and deeply personal information was at high risk. To safeguard the data, practitioners applied advanced cybersecurity measures to create the world's first nearly 100% digital archive. Peacebuilders encrypted the data to protect vulnerable victims from retaliation, prevent bad actors from deleting evidence of war crimes and ensure these testimonies remain globally accessible to prevent history from repeating itself.
Resolving modern conflict requires a specialized toolkit, and the demand for peacebuilders is growing rapidly. To have a successful security studies career, skills such as critical thinking, holistic analysis, cross-cultural communication, cybersecurity literacy and discretion are essential. If you’re ready to turn your passion for justice into tangible impact, the University of San Diego’s Joan B. Kroc School of Peace Studies offers a Security Studies Concentration designed for aspiring peacebuilders like you.
Available to MA in Peace and Justice (MAPJ) and MS in Conflict Management and Resolution (MSCMR) students, this concentration bridges the gap between theory and reality. Graduates leave the program equipped to:
Students explore these life-saving dynamics through unique courses such as Hybrid Wars and Grey-Zone Conflicts and Cyberspace & Cybersecurity. Plus, students can gain an invaluable global perspective through an immersive two-week study-abroad program in Madrid, Spain.
