Containment Without Capacity: Sudan’s Displacement and the Limits of Border Politics
Strategic Argument and Areas of Debate
The fundamental contradiction of the regional crisis stemming from Sudan is that neighbouring states rely on strict border securitisation to manage mass displacement without possessing the required institutional and economic capacity to sustain these regimes. Consequently, this severe imbalance transforms what begins as a humanitarian challenge into a self-reinforcing cycle of informality, unofficial mobility, and regional destabilisation.
Executive Summary
The TRT World Research Centre analysis of the displacement crisis originating from Sudan demonstrates that regional spillover into neighbouring states such as Chad and South Sudan is primarily driven by a critical failure in host-state capacity rather than mere population inflows. As entities like the UN International Organization for Migration and the UN Office for the Coordination of Humanitarian Affairs document escalating displacement from conflict zones like El-Fasher, host governments increasingly deploy securitised containment strategies that lack the underlying economic and administrative infrastructure to function effectively. Ultimately, this approach severely compromises the fundamental principle of non-refoulement and accelerates systemic instability across border regions, demanding an immediate shift from exclusionary containment towards comprehensive, coordinated capacity-building initiatives.
Analytical Framework and Key Drivers
- Containment Versus Capacity Imbalance: Restrictive border management techniques inherently fail when neighbouring states cannot mobilise the necessary infrastructure, healthcare, and economic resources to support sudden population influxes.
- Sudden Displacement Shock Moments: Rapid forced migrations driven by conflict escalations, such as the violent surge in El-Fasher beginning in October 2025, overwhelm border systems and provoke immediate securitised responses over sustainable management.
- Expansion of Unofficial Mobility: Hardened border enforcement naturally forces displaced populations into undocumented pathways, which dramatically reduces state oversight and expands regional informality.
- Erosion of Protection Frameworks: Administrative delays, restrictive livelihood policies, and constrained urban resources fundamentally undermine the principle of non-refoulement, creating severe legal vulnerabilities for displaced persons.
- Macroeconomic Constraints on Governance: Escalating debt and rising inflation in host nations directly curtail available public expenditure, fundamentally limiting the ability to manage displacement and driving exclusionary border politics.
Strategic Assessment & Empirical Findings
- Following the Rapid Support Forces takeover of El-Fasher, violent conflict generated a massive displacement shock, with more than 62,000 people displaced within just four days after October 26.
- The broader crisis stemming from the outbreak of violence in Sudan on April 15, 2023, has left over 30 million people requiring urgent humanitarian assistance and forcibly displaced more than 14 million people.
- South Sudan faces profound constraints in absorbing displaced populations due to overlapping crises, with approximately 9.3 million people already requiring humanitarian aid as of October 2025.
- Regional economic pressures are severely compounding the crisis, exemplified by extremely high projected inflation rates for 2026, particularly in South Sudan, which is confronting a staggering 34.4% inflation rate.
- State efforts to tighten border security through strict documentation and screening regimes inadvertently accelerate the growth of informal economies and amplify risks to state authority.
- Establishing minimum implementation-level protection requirements and shifting cross-border transit lines into coordinated management nodes are essential operational steps to stabilise border regions and reduce regional fragility.
Geopolitical Trajectories & Policy Risks
- South Sudan faces an escalating risk of comprehensive state destabilisation as profound macroeconomic constraints and existing humanitarian burdens fatally undermine its capacity to absorb continual shock inflows from Sudan.
- The habitual reliance by border administrations on restrictive securitisation practices without concurrent institutional capacity building heavily risks normalising arbitrary detentions and forced deportations, critically degrading international protection frameworks.
- Absent operational coordination and robust funding from the international donor community, host nations bordering Sudan will inevitably resort to an unsustainable politics of closure, fundamentally intensifying border-region political tensions and empowering informal smuggling networks.
Critical Policy Questions & Responses
Question 1 How does the widening gap between border securitisation and institutional capacity across neighbouring states amplify the regional destabilisation caused by the conflict in Sudan?
Answer: When nations like South Sudan and Chad respond to sudden displacement shocks with stringent border controls but lack the administrative infrastructure to register and support arrivals, displaced populations are forced into unmonitored, informal pathways. This inevitable expansion of unofficial mobility severely compromises regional security, strains local economies, and undermines overarching governance frameworks throughout border regions.
Question 2 Why do acute conflict events like the siege of El-Fasher fundamentally transform the border management strategies of surrounding African nations?
Answer: Sudden explosions of violence, such as the rapid displacement of over 62,000 individuals from El-Fasher in late October 2025, act as extreme shock moments that entirely compress the timeframe for political decision-making. Overwhelmed by the sheer velocity of the influx, neighbouring authorities immediately default to aggressive securitisation and containment rather than sustainable capacity-building, cementing highly restrictive border regimes.
Question 3 What are the long-term consequences of restricting formal livelihood access for displaced Sudanese populations in host-state urban centres?
Answer: Denying refugees formal economic opportunities directly forces vulnerable populations into the black market, rapidly expanding informality while artificially reinforcing domestic narratives regarding security risks. As this cycle entrenches itself, local political discourse inevitably hardens, prompting authorities to impose even narrower legal avenues that ultimately compromise the fundamental principle of non-refoulement.
Question 4 How do prevailing macroeconomic vulnerabilities in countries like South Sudan restrict their ability to establish effective humanitarian management nodes?
Answer: Severe structural economic challenges, including a projected 34.4% inflation rate for 2026 in South Sudan, actively dismantle the fiscal space required to construct temporary housing, administer health screenings, or maintain basic public services for new arrivals. Consequently, this profound absence of baseline operational capacity guarantees that state responses remain focused on exclusionary constraints rather than developing functional, predictable refugee protection networks.
