The civil wars raging in Sudan and South Sudan have inflicted profound human suffering and destabilized not only these two nations but also the broader African region. These conflicts, marked by intense violence, ethnic divisions, and political power struggles, have triggered massive displacement, economic collapse, and humanitarian crises. Beyond their immediate borders, the wars have generated ripple effects that threaten regional security, economic development, and peace across Africa. This analysis explores the multifaceted impact of these civil wars, drawing on the latest data, facts, and key stakeholder perspectives to understand how they jeopardize Africa’s security landscape.
The Conflict in Sudan: A Nation Engulfed in Violence
Since April 15, 2023, Sudan has been embroiled in a brutal civil war primarily between the Sudan Armed Forces (SAF), led by General Abdel Fattah al-Burhan, and the paramilitary Rapid Support Forces (RSF), commanded by Mohamed Hamdan Dagalo, known as “Hemedti.” This fierce power struggle has turned major cities into battlegrounds, with widespread fighting reported across the country.
According to the Armed Conflict Location & Event Data Project (ACLED), between April 2023 and March 2025, Sudan experienced at least 11,292 violent incidents, averaging 16 attacks per day. The Sudanese army accounted for about 50% of these incidents, the RSF for 38%, while other armed groups, including Darfur militias, comprised the remainder.
The human toll has been staggering. The conflict has displaced over 14 million people, which is approximately 30% of Sudan’s 48 million population, forcing them to flee their homes amid escalating violence. More than half of the country’s population now depends on humanitarian aid to survive. By November 2024, there were over 28,700 reported fatalities, including more than 7,500 civilians killed in direct attacks, though some estimates suggest the death toll could be as high as 150,000. The war has also precipitated a severe health crisis, with nearly 60,000 cholera cases and over 1,640 deaths reported as of April 2025, exacerbated by the collapse of healthcare infrastructure.
The scale and intensity of this conflict have overwhelmed Sudan’s institutions and infrastructure, turning the country into one of the world’s largest humanitarian emergencies. The fragmentation of armed groups and the involvement of various militias complicate efforts toward peace and stability. The ongoing violence has also destabilized neighboring countries, as refugees cross borders in search of safety, spreading insecurity across the region.
South Sudan’s Protracted Civil War and Its Lingering Impact
South Sudan’s civil war, which began in December 2013, has been fueled by ethnic rivalries and political power struggles, primarily between President Salva Kiir, a Dinka, and former Vice President Riek Machar, a Nuer. This conflict has resulted in an estimated 383,000 deaths — including both direct violence and war-related causes such as famine and disease — and displaced over 4 million people. Approximately 1.8 million South Sudanese remain internally displaced, while 2.5 million have fled as refugees to neighboring countries, including Uganda and Sudan.
The war devastated South Sudan’s economy and food security. The 2017 famine, which affected millions, was a direct consequence of the conflict’s disruption of agriculture and markets. Even in 2025, violence persists in key states such as Upper Nile, Unity, and Jonglei, where over 250,000 new internal displacements were recorded in early 2025. Additionally, South Sudan hosts over 1 million refugees and returnees from Sudan, placing further strain on its fragile resources and infrastructure.
The ongoing instability in South Sudan has hindered development efforts and perpetuated cycles of violence and poverty. Ethnic militias and localized conflicts have fragmented authority, undermining governance and creating security vacuums that can be exploited by extremist groups. This fragility not only threatens South Sudan’s future but also poses risks to the broader region’s stability.
Regional Security Implications: Displacement and Cross-Border Spillover
One of the most immediate and visible consequences of the civil wars in Sudan and South Sudan is the massive displacement of people, which has overwhelmed neighboring countries and destabilized border regions. Sudan’s conflict alone has forced nearly 4 million refugees to seek shelter in countries such as South Sudan, Chad, Ethiopia, Egypt, Libya, and the Central African Republic. South Sudan, grappling with its own internal displacement crisis, hosts over 1 million refugees from Sudan.
These large refugee flows place enormous pressure on host countries’ resources, infrastructure, and security apparatuses. Refugee camps and informal settlements often lack adequate sanitation, healthcare, and protection, making them vulnerable to disease outbreaks and exploitation by armed groups. Competition for scarce resources between refugees and local populations can fuel tensions, sometimes escalating into violence.
The cross-border movement of displaced populations also facilitates the spread of armed groups and criminal networks. Refugee camps can become recruitment grounds for militias and extremist organizations, thereby extending the conflict’s reach beyond national borders. The instability generated by these population movements threatens to undermine peace and security in the wider Horn of Africa and Sahel regions.
Fragmentation of Armed Groups and Proliferation of Violence
Both Sudan and South Sudan’s civil wars have been characterized by the fragmentation of armed groups beyond the main warring parties. In Sudan, alongside the SAF and RSF, numerous militias from Darfur, the Sudan People’s Liberation Movement (SPLM), and various clan-based factions contribute to the complexity of the conflict. This proliferation of armed actors complicates peace negotiations and perpetuates cycles of violence.
Similarly, South Sudan’s conflict involves a patchwork of ethnic militias and localized armed groups, often engaged in brutal attacks on civilians and humanitarian workers. The fragmentation undermines centralized authority and creates security vacuums that extremist groups can exploit. This environment of lawlessness and insecurity threatens not only the immediate conflict zones but also the broader region’s stability.
The presence of multiple armed factions with shifting alliances makes it difficult to implement ceasefires or peace agreements. It also complicates the deployment of effective peacekeeping forces, as regional bodies and the African Union face significant challenges in navigating the complex political and ethnic dynamics at play.
Economic Devastation and Food Insecurity Across the Region
The civil wars have inflicted severe damage on the economies of Sudan and South Sudan, with ripple effects felt throughout the region. South Sudan’s economy has been particularly hard hit, with real income halving since the outbreak of civil war in 2013. Inflation soared above 300% per annum during the conflict’s peak, and the destruction of agricultural lands and disruption of markets have led to chronic food insecurity.
Sudan’s economy has also been crippled by the ongoing war. The destruction of infrastructure, disruption of trade routes, and collapse of public services have exacerbated hunger and disease outbreaks. The World Food Programme has warned of the “world’s largest hunger crisis,” with over 30 million people across the region requiring humanitarian assistance.
Food insecurity fuels further instability by increasing competition for scarce resources and driving displacement. Malnutrition weakens populations, making them more vulnerable to disease and reducing their ability to contribute to economic recovery. The economic devastation thus creates a vicious cycle that perpetuates conflict and undermines long-term peace prospects.
International and Regional Responses to the Crises
Efforts to mediate peace and provide humanitarian assistance have faced significant obstacles. The leaders of Sudan’s SAF and RSF have repeatedly refused to cease hostilities, prolonging the conflict. Regional actors have often taken sides, complicating diplomatic efforts and sometimes exacerbating tensions.
The United Nations and humanitarian agencies continue to call for increased support to address the worsening conditions. However, the scale of the crises and the security challenges on the ground limit the effectiveness of aid delivery. The African Union and regional bodies have struggled to enforce peace agreements or deploy peacekeeping forces capable of stabilizing the situation, hindered by the complex ethnic and political dynamics.
The failure to resolve these conflicts threatens to destabilize not only Sudan and South Sudan but also the wider Horn of Africa and Sahel regions, with implications for international security and development.
The Human Cost and Moral Imperative
The human suffering caused by these civil wars is immense. Beyond the staggering death tolls and displacement figures lie countless stories of families torn apart, children orphaned, and communities devastated. The humanitarian crises have overwhelmed health systems, leading to outbreaks of diseases such as cholera and malnutrition-related deaths.
Carl Skau of the World Food Programme has emphasized the urgency of the situation, stating,
“We are running out of time,”
as millions face starvation and disease. Similarly, Christopher Nyamandi, Director of Save the Children in South Sudan, highlighted the moral dimension of the crisis, asserting,
“There should be global moral outrage that decisions made by powerful people in other countries have resulted in child fatalities within just weeks.”
These statements underscore the ethical responsibility of the international community to act decisively to alleviate suffering and support peace efforts.
The Urgent Need for Coordinated Action
The civil wars in Sudan and South Sudan represent a complex and multifaceted crisis with far-reaching implications for Africa’s security. The staggering human toll, massive displacement, proliferation of armed groups, and economic devastation threaten to destabilize the entire region. Neighboring countries face increased security risks from refugee influxes and cross-border violence, while international and regional actors struggle to broker peace amid entrenched divisions.
Addressing these conflicts requires a coordinated approach that combines immediate humanitarian aid, sustained peace mediation, and long-term development support. Failure to do so risks perpetuating cycles of violence and instability that undermine not only Sudan and South Sudan but also the broader African continent’s prospects for peace, security, and prosperity.
The international community must heed the warnings of humanitarian leaders and analysts alike and mobilize the political will and resources necessary to end these wars and rebuild shattered societies. Only through collective action can the devastating impact of Sudan and South Sudan’s civil wars on Africa’s security be reversed.
