A Nigerian criminologist, Dr. Paul Oluwatosin Bello, has drawn international attention to the deep-seated vulnerabilities in South Africa’s border management system, revealing how porous borders, fragmented enforcement, and institutional weaknesses are enabling a broad spectrum of cross-border crimes (especially human trafficking).

Dr. Bello, who earned his PhD in Policing (Safety & Security) in South Africa, conducted fieldwork in the Limpopo province, a critical border region adjoining Zimbabwe, Mozambique, and Botswana. His research offers a comprehensive analysis of the challenges undermining South Africa’s capacity to prevent and disrupt cross-border criminal activity, including human smuggling, arms trafficking, illicit trade, and organised robbery syndicates.

“These crimes do not operate in silos,” Dr. Bello said. “They form a complex, interconnected ecosystem of transnational criminality—exploiting weak border controls, under-resourced security personnel, and corruption within enforcement agencies.”

Despite South Africa’s relatively advanced legal and institutional frameworks, Dr. Bello’s findings suggest a growing disconnect between policy and practice. His work identifies critical failures in inter-agency collaboration, intelligence-sharing, and frontline response. He attributes the rise of cross-border crime to low procedural accountability, lack of scenario-based training, and a reactive, rather than preventive, approach to enforcement.

Dr. Bello’s academic journey began at Covenant University, Nigeria, where he examined the Child Rights Act and its implementation in curbing child trafficking. He later broadened his scope through a Master’s thesis in Lagos that framed human trafficking within a human rights and institutional governance context. These early investigations laid the foundation for his decision to examine cross-border crime in Southern Africa, a region grappling with complex transnational security threats.

“My doctoral research moved beyond trafficking as an isolated issue and explored how organized crime networks exploit institutional gaps across borders. What I found was a deeply fragmented enforcement architecture that inadvertently enables cross-border criminal networks,” he explained.

As part of his PhD, Dr. Bello proposed a multi-tiered criminal justice response model, advocating for an intelligence-driven, multi-agency task force that integrates border security, crime analytics, prosecution, and victim support services. His recommendations emphasized the need for real-time data sharing, regional cooperation, and continuous capacity building among law enforcement agencies.

Several of his policy suggestions were later adopted by experts within South Africa’s national security apparatus. Notably, his work informed the creation of data-sharing platforms among Southern African Development Community (SADC) countries, enhancing cross-border intelligence coordination. He also collaborated with local organizations to launch community outreach and early-warning systems in rural border towns, which helped reduce criminal recruitment and illicit trade activity.

Following his PhD, Dr. Bello undertook a postdoctoral fellowship at the University of KwaZulu-Natal, where he considered the intersection between cross-border crime and domestic violence, robbery, and homicide, warning that border-related criminality often filters into urban centres. His recent studies argue for structural police reforms, greater public oversight, and community-based safety partnerships as long-term deterrents.

To counter youth involvement in transnational criminal networks, Dr. Bello recommends data-informed prevention strategies, community engagement, and targeted economic interventions. He asserts that youth disenfranchisement, fueled by unemployment and marginalization, creates a fertile ground for criminal recruitment.

“Addressing cross-border crime isn’t just a matter of security hardware—it’s also about governance, equity, and public trust. A secure border begins with resilient institutions and empowered communities,” he noted.

Now a respected voice in transnational security and criminology, Dr. Bello continues to advise policy institutions, civil society organizations, and law enforcement agencies on effective approaches to cross-border crime prevention and institutional reform.

“My work is ultimately about building systems that protect the vulnerable, hold institutions accountable, and promote a safer, more just society,” he concluded.
