The Nile Water Wars: Egypt, Ethiopia, and Sudan at Odds
The Nile Water Wars: Egypt, Ethiopia, and Sudan at Odds
1. A Contested River
Stretching over 6,850 kilometers, the Nile is renowned as the world's longest river, a vital artery sustaining life for hundreds of millions across eleven Northeast African nations. Its basin covers roughly 10% of the African continent, hosting 40% of its population. For millennia, its predictable floods nourished civilizations, none more so than Egypt, famously dubbed "the gift of the Nile." Yet, this shared lifeline, particularly crucial for Egypt, Sudan, and Ethiopia, is increasingly a source of profound geopolitical tension. Access to freshwater is universally recognized as a fundamental human right, essential for life, dignity, health, agriculture, and industry. However, in arid and rapidly developing regions like the Nile basin, water is an increasingly scarce and contested resource. Global predictions paint a stark future, with the UN forecasting that 1.8 billion people will face absolute water scarcity by 2025, and nearly half the world's population living under high water stress by 2030, with Africa disproportionately affected.
At the heart of the current Nile dispute lies the Grand Ethiopian Renaissance Dam (GERD), a colossal hydropower project on the Blue Nile, the Nile's main tributary, originating in Ethiopia. Initiated in 2011, the GERD embodies Ethiopia's aspirations for economic development and energy independence, promising to double its electricity generation. However, for downstream Egypt, which depends on the Nile for over 97% of its freshwater, the dam represents a potential existential threat, jeopardizing its water security, agriculture, and stability. Sudan, located between Ethiopia and Egypt, faces a complex calculus, anticipating potential benefits like flood control and cheap electricity, but also harbouring deep concerns about the dam's safety and operational impacts. A decade of trilateral negotiations aimed at finding a mutually agreeable framework for the dam's filling and operation has repeatedly failed, culminating most recently in a collapse of talks in December 2023 and Egypt's subsequent withdrawal from the negotiation track in early 2024. This hydro-political deadlock, marked by Ethiopia's unilateral filling and operation of the dam and increasingly strident warnings from Egypt, poses a serious threat to regional peace and security. The conflict transcends the technical aspects of dam management; it is fundamentally a clash between Egypt's historically dominant position rooted in colonial-era water allocations, Ethiopia's modern push for development based on principles of equitable resource utilization, and Sudan's struggle to navigate its interests amidst regional power plays and internal turmoil. This complex interplay is amplified by nationalist sentiments, deep-seated mistrust, and the looming specter of climate change.
2. History, Colonialism and Water Rights
The current tensions over the Nile cannot be understood without examining the historical framework that has governed its waters for much of the past century – a framework largely shaped by colonial interests and Egypt's subsequent efforts to maintain its dominance.
2.1 Early Treaties
While numerous agreements touched upon the Nile, two stand out for their lasting impact. The 1902 Anglo-Ethiopian Treaty saw Ethiopia's Emperor Menelik II engage with Great Britain "not to construct or allow to be constructed any work across the Blue Nile, Lake Tana, or the Sobat, which would arrest the flow of their waters into the Nile". Though signed by Ethiopia, its validity and applicability are contested by Addis Ababa today, partly on the grounds that Britain later recognized Italy's occupation of Ethiopia. It remains, however, the only historical agreement directly involving Ethiopia concerning Nile flow regulation.
Far more consequential was the 1929 Nile Waters Agreement, an exchange of notes between Egypt and Great Britain, the latter acting on behalf of its colonies: Sudan, Uganda, Kenya, and Tanganyika (now Tanzania). This agreement formalized Egypt's privileged access. It allocated 48 billion cubic meters (BCM) of the Nile's estimated 84 BCM annual flow to Egypt and a mere 4 BCM to Sudan. Crucially, it reserved the entire flow during the critical dry season (January 20 to July 15) for Egypt's irrigation needs and granted Cairo the right to monitor Nile flows in upstream countries. Perhaps most significantly, it gave Egypt veto power over any upstream projects that could potentially affect its water share. Ethiopia and other upstream nations were entirely excluded from this arrangement. From the perspective of upstream states, particularly after achieving independence, the 1929 treaty is viewed as an illegitimate colonial relic, imposed without their consent and therefore not binding under the "Clean Slate" theory of state succession, which holds that newly independent states inherit boundary treaties but not other obligations of their colonizers. Egypt, conversely, has historically invoked a "Continuity Theory," arguing that such water agreements possess an immutability akin to border treaties, requiring the consent of all original parties for modification.
2.2 The 1959 Agreement
Following Sudan's independence in 1956, Khartoum sought to renegotiate the terms of the 1929 Agreement. This led to the 1959 "Agreement for the Full Utilization of the Nile Waters," signed exclusively between Egypt (then the United Arab Republic) and Sudan. This bilateral treaty aimed explicitly to enable the two downstream nations to control and fully utilize the river's flow, building upon their "acquired rights" established in 1929.
The 1959 Agreement dramatically revised the water allocations. Based on an agreed average annual flow of 84 BCM measured at Aswan, and accounting for an estimated 10 BCM annual loss due to evaporation and seepage from the planned Aswan High Dam reservoir, the net yield was calculated at 74 BCM. From this net yield, Egypt's share was increased to 55.5 BCM annually, and Sudan's share rose substantially to 18.5 BCM. This allocation effectively accounted for the entire usable flow of the Nile as understood at the time, leaving no provision for the water needs or development aspirations of the nine upstream riparian countries, including Ethiopia, the source of over 85% of the Nile's water.
Key provisions cemented this downstream control: Egypt was granted the right to construct the Aswan High Dam (Sudd el Aali) for over-year storage, while Sudan was permitted to build the Roseires Dam on the Blue Nile to utilize its increased share. Egypt agreed to pay Sudan 15 million Egyptian pounds as compensation for the flooding of Sudanese land (including the town of Wadi Halfa) by the Aswan reservoir. The agreement also outlined plans for joint projects to increase the river's yield by reducing water losses in upstream swamps (like the Jonglei Canal project in South Sudan), with costs and benefits to be shared equally. A Permanent Joint Technical Commission was established for cooperation, research, and supervision of works. Critically, the agreement stipulated that Egypt and Sudan must adopt a "unified view" before entering negotiations with any other riparian state regarding Nile waters. Any future water allocation agreed upon for an upstream state would be deducted in equal parts from Egypt's and Sudan's shares, effectively maintaining their collective control over the river's total flow.
The 1959 agreement has been sharply criticized as an exclusionary and anachronistic arrangement. By allocating the entire flow based solely on the perceived needs and "acquired rights" of the two furthest downstream states, it disregarded the sovereign rights and developmental needs of the nations where the Nile originates. This approach stands in stark contrast to the modern principles of international water law, namely equitable and reasonable utilization, the obligation not to cause significant harm, and the duty to cooperate. It effectively positioned Egypt and Sudan as the self-proclaimed "masters" of the Nile, requiring upstream states to seek their permission for development. This institutionalization of a zero-sum framework, where downstream "shares" consume the entire resource, is a fundamental source of the current conflict. Any attempt by an upstream country like Ethiopia to utilize water under the principle of "equitable utilization" inherently challenges the legitimacy of these historically enshrined, but exclusionary, downstream allocations, forcing Egypt and Sudan to defend "historical rights" derived from this agreement.
2.3 Egypt's Historical Control
For decades, Egypt successfully translated the legal advantages conferred by these treaties into practical dominance over the Nile basin, a position often described as "hydro-hegemony". Hydro-hegemony refers to control over shared water resources achieved through a combination of factors, including advantageous riparian position (though Egypt is downstream), military strength, economic power, technical capacity, infrastructure control (like the Aswan High Dam), and geopolitical influence. Despite its geographically vulnerable downstream location, Egypt leveraged its relative political stability, military capabilities, economic weight, strategic importance in the Middle East (earning support from global powers), and the sheer fact of its existing water infrastructure to dictate terms and effectively block internationally funded development projects on the Nile upstream, particularly in Ethiopia. Controlling Sudan, the immediate upstream neighbor with significant agricultural potential, was a cornerstone of Egypt's Nile strategy.
However, this dominance was inherently fragile. It depended significantly on the continued internal fragmentation, political instability, and lack of financial and technical resources within upstream states, especially Ethiopia. Egypt, in a sense, benefited from the disarray in countries like Ethiopia, which prevented them from undertaking major water development projects. As the furthest downstream nation, Egypt's control was always vulnerable to changes upstream. Upstream populations grew increasingly resentful of this perceived injustice. Ugandan commentator Charles Onyango-Obbo captured this sentiment, questioning how Egypt could enjoy unlimited access while blocking landlocked Uganda at the Nile's source. Ethiopian leaders, like the late Prime Minister Meles Zenawi, articulated this frustration, warning that upstream populations would eventually become "too desperate to care about diplomatic niceties" and asserting that the only viable solution was a "win-win" outcome, rejecting Egypt's perceived "I win if you lose" approach. The construction of the GERD, therefore, represents more than just an infrastructure project; it signifies a fundamental shift in the basin's power dynamics. It emerged as Ethiopia achieved greater internal stability and economic ambition, challenging a hydro-hegemonic order that was always contingent on upstream weakness and specific geopolitical alignments.

3. Ethiopia's Dam: The GERD
Against the backdrop of historical exclusion and perceived inequity, Ethiopia embarked on the Grand Ethiopian Renaissance Dam project in 2011, a venture driven by profound national aspirations and designed to fundamentally alter the country's energy landscape and regional standing.
3.1 Why Ethiopia Built the Dam
The primary driver behind the GERD is Ethiopia's urgent need for electricity. With over half its population, estimated at over 120 million people, lacking access to reliable power, the dam is central to the government's goal of achieving universal electrification, initially targeted for 2025. The massive hydropower potential of the GERD is seen as the key to unlocking Ethiopia's economic development. The generated electricity is intended to power nascent manufacturing industries, support the expansion of agriculture through enhanced irrigation capabilities, create thousands of jobs, and lift millions out of poverty. Beyond domestic needs, Ethiopia aims to become a major regional power exporter, selling electricity to neighboring countries like Kenya, Djibouti, and Sudan, potentially generating substantial annual revenue (estimated up to $1 billion) and fostering economic integration.
The GERD holds immense symbolic value for Ethiopia. It is portrayed as a testament to national sovereignty, self-reliance, and the determination to harness the nation's natural resources for its own benefit, breaking free from historical constraints imposed by downstream dominance. The fact that the multi-billion dollar project was largely financed domestically through government bonds and public contributions has fostered a powerful sense of national pride and unity, setting an example of self-sufficiency for other African nations. The project is also framed within Ethiopia's foreign policy as a tool for peaceful cooperation, utilizing transboundary resources equitably for mutual benefit and regional integration, promoting clean energy, and combating climate change.
3.2 Building and Funding the Dam
The concept of a major dam on the Blue Nile dates back decades, with initial surveys conducted by the United States Bureau of Reclamation between 1956 and 1964, identifying potential sites. However, political instability in Ethiopia and downstream opposition, particularly from Egypt which actively worked to block international funding for such projects, delayed any concrete action for years.
The project, initially known as "Project X" and later the "Millennium Dam," was officially revived in the 2000s. Construction began in earnest shortly after the project was publicly announced. On March 31, 2011, a $4.8 billion contract was awarded without competitive bidding to the Italian construction giant Salini Impregilo (now Webuild). The foundation stone for the renamed Grand Ethiopian Renaissance Dam was laid by then-Prime Minister Meles Zenawi on April 2, 2011. French company Alstom was later contracted to supply turbines and electromechanical equipment.
Financing the dam, with an estimated cost ranging from $4.7 to $5 billion, posed a significant challenge. Due to the project's controversial nature and opposition from Egypt and Sudan, securing international loans from institutions like the World Bank proved difficult. Consequently, Ethiopia embarked on an ambitious self-financing campaign, relying heavily on the sale of government bonds to citizens and the diaspora, as well as other domestic fundraising efforts. While hailed as a success in national mobilization, some analyses point to potential cost overruns and the lack of initial competitive bidding as potential financial risks. Construction progressed steadily, albeit with some reported delays. By early 2023, the dam was reported as 90% complete, reaching 94.6% by early 2024. In October 2024, Ethiopian Prime Minister Abiy Ahmed announced that the construction of the dam was 100% complete.
3.3 Dam Details and Status
The GERD is an engineering marvel, designed as a roller-compacted concrete (RCC) gravity dam. The main dam stands 155 meters tall and stretches 1,780 meters across the Blue Nile gorge. It is complemented by a large rock-fill saddle dam, approximately 50 meters high and 5.2 kilometers long, which helps contain the reservoir. The total volume of concrete used in the main dam is about 10.4 million cubic meters. The dam features three spillways (one gated with six radial gates, and two ungated) designed to manage floodwaters, with a maximum capacity of 19,370 cubic meters per second.
The dam impounds the Millennium Reservoir, which has a vast total storage capacity of 74 billion cubic meters (BCM). Of this, the active or 'live' storage used for power generation is approximately 59.2 BCM, with the remaining 14.8 BCM constituting inactive or 'dead' storage. At its full supply level, the reservoir covers a surface area of 1,874 square kilometers.
The GERD's primary purpose is hydropower generation. Its final installed capacity is 5.15 gigawatts (GW) or 5,150 megawatts (MW), making it the largest hydroelectric power plant in Africa. This capacity is slightly reduced from earlier plans that envisaged 6,000 MW or even 6,450 MW. Power is generated by 13 Francis-type turbines housed in two power stations on either bank of the river: eleven turbines are rated at 400 MW each, and two at 375 MW each. The expected average annual energy generation is estimated at 15.76 terawatt-hours (TWh).
The filling of the massive reservoir began unilaterally in July 2020, a major point of contention with Egypt and Sudan. The process occurred in stages during the rainy seasons:
First Filling (July 2020): Reached an elevation of 540 meters, impounding approximately 4.9 BCM.
Second Filling (July 2021): Raised the water level to around 575 meters.
Third Filling (August 2022): Reached 600 meters elevation.
Fourth Filling (September 2023): Reached approximately 625 meters, bringing the total stored volume to around 41 BCM.
Fifth Filling (July-September/October 2024): Began in July 2024 and was declared complete by Ethiopia in the following months. This phase aimed to raise the water level to around 640 meters, potentially adding another 23 BCM and bringing the total stored volume close to its maximum live storage capacity of around 64 BCM. Following this filling, Egypt reported a one-month delay in the arrival of Nile floodwaters. As of late 2024/early 2025, the stored volume was reported to be stable at around 60 BCM.
Operationally, the GERD began generating electricity for the first time on February 20, 2022, when one of the 375 MW turbines was commissioned. A second 375 MW turbine came online in August 2022. The third and fourth turbines, both 400 MW units, were commissioned in August 2024. This brought the total number of operational turbines to four by late 2024, with reports suggesting a fifth and sixth may have come online by February 2025. However, there have been reports suggesting these turbines operated only briefly or intermittently after commissioning, pausing for extended periods. This has raised questions about potential technical issues, the readiness of the transmission network to distribute the generated power, or deliberate operational decisions.
While Ethiopia consistently emphasizes the dam's state-of-the-art engineering, adherence to international standards, and safety, downstream nations remain wary. The deep mistrust between the parties means that technical assurances from Addis Ababa are often met with skepticism in Cairo and Khartoum, particularly given the lack of jointly agreed-upon, comprehensive impact studies and the perceived lack of transparency surrounding the dam's construction and operational plans. The failure to complete the studies mandated by the 2015 Declaration of Principles before commencing filling operations exacerbated these concerns. Ethiopia's unilateral approach, driven by its national development timeline, has prevented the establishment of the cooperative framework that downstream countries argue is necessary to verify safety and mitigate potential negative impacts effectively.
4. Egypt's Concerns
For Egypt, the furthest downstream nation, the Grand Ethiopian Renaissance Dam looms not merely as an infrastructure project but as a potential threat to its very survival, challenging its historical reliance on the Nile and raising profound concerns about water security, agriculture, and economic stability.
4.1 Water Security Fears
Egypt's dependence on the Nile is almost absolute. Receiving negligible rainfall, the country relies on the river for approximately 97% of its freshwater needs. This unique hydrological vulnerability makes control over the Nile's flow a matter of paramount national security, an "existential issue" repeatedly emphasized by Egyptian leaders. The primary fear is that the GERD, particularly during its filling phase and subsequent long-term operation, will significantly curtail the volume of water reaching Egypt through the Aswan High Dam. Projections vary, but some estimates suggested a potential 25% reduction in supply during the filling period, while others calculated potential decreases ranging from 14% (over a 10-year fill) to a catastrophic 50% (over a 3-year fill). Such reductions are perceived as directly threatening the livelihoods and well-being of Egypt's population of over 100 million people.
These concerns are amplified by Egypt's pre-existing water stress. The country already faces an annual water deficit, estimated at 13.5 BCM in 2016 and projected to grow. Per capita water availability has fallen below the international water poverty line and is expected to decline further, pushing Egypt towards "absolute water scarcity" by 2025. Rapid population growth, adding millions each year, intensifies this pressure. Against this backdrop, any substantial reduction in Nile flow caused by the GERD is viewed as potentially devastating. Consequently, Egypt has consistently framed the GERD dispute in national security terms. Its diplomatic position has centered on demanding a comprehensive, legally binding agreement that guarantees its "historical rights" (based on the 1929 and 1959 treaties) and ensures minimum water flows, especially during drought years. Frustrated by the lack of progress in negotiations and Ethiopia's unilateral actions, Egypt's stance has hardened. It officially withdrew from the negotiation process in early 2024 and has issued increasingly strong warnings, including letters to the UN Security Council stating it reserves the right under the UN Charter to take all necessary measures to defend its water and national security.
4.2 Economic and Agricultural Impacts
The potential impacts of reduced Nile flow extend deep into the fabric of Egyptian society and its economy. Agriculture, heavily reliant on Nile irrigation, is a critical sector, providing food and employing a significant portion of the population, particularly in rural areas. A reduction in water availability could lead to a substantial loss of arable land; estimates range from 200,000 acres lost for a 2% flow reduction to a 22% decrease in irrigated land if inflows to Aswan drop significantly. One Egyptian projection warned that unilateral GERD operation could threaten 1.1 million livelihoods and 15% of the country's agricultural land. Such losses would inevitably reduce agricultural productivity, potentially forcing Egypt to increase its already substantial food imports, displacing farming communities, and potentially fueling social unrest. The impact could be particularly severe for the majority of Egyptian farms, which are small holdings located along the Nile banks.
Beyond agriculture, the economic consequences could be severe. Reduced agricultural output would negatively affect GDP and employment. Furthermore, the GERD's operation could diminish the hydropower generation capacity of Egypt's own Aswan High Dam, with potential reductions estimated between 20% and 40%, further straining the national energy supply. The Egyptian government fears that these combined pressures could lead to heightened socio-economic tensions, displacement, and an increase in illegal migration. These domestic economic worries are compounded by existing pressures, such as the significant loss of revenue from the Suez Canal due to Houthi attacks in the Red Sea since late 2023.
Coordination between the GERD and the Aswan High Dam (AHD) is another critical concern. While proponents suggest GERD could offer benefits like reduced evaporation from Lake Nasser compared to AHD, the lack of agreed-upon operating rules creates significant uncertainty for Egypt's management of the AHD, which is vital for regulating downstream flows, providing irrigation water, and generating power. While Egypt managed to keep AHD levels relatively stable during the initial years of GERD filling, analysts suggest this may have been due to unusually high rainfall in the Blue Nile catchment rather than cooperative dam management. Environmental concerns also persist, including the potential for increased soil salinity in the Nile Delta due to lower flows and reduced groundwater recharge, further threatening agriculture.
The consistent framing of the GERD issue as an "existential threat" by Cairo, coupled with the country's significant military capabilities and the recent breakdown of diplomacy, creates a volatile situation. While analysts debate the likelihood of direct military confrontation, deeming an attack on the dam itself improbable due to the catastrophic flooding it would cause in Sudan, the potential for escalation remains real. Egypt's increasingly assertive diplomatic posture at the UN, its withdrawal from talks, and its recent military deployments and agreements with Somalia – seen by some as a move to exert pressure on Ethiopia – signal Cairo's determination not to accept the status quo. A future severe drought, leading to tangible reductions in water availability downstream, could act as a trigger, potentially leading to conflict, whether direct, indirect, or through regional proxies.
5. Sudan's Position
Positioned geographically and politically between the upstream ambitions of Ethiopia and the downstream anxieties of Egypt, Sudan faces a uniquely complex situation regarding the GERD. Its stance has often been characterized by ambivalence, weighing potential benefits against significant risks, a calculation now profoundly complicated by the country's devastating internal conflict.
5.1 Potential Gains
For Sudan, the GERD offers several potential advantages. Perhaps the most significant is the prospect of improved flood control. The Blue Nile is prone to extreme seasonal flooding that regularly causes widespread damage and displacement in Sudan. By regulating the river's flow, the GERD could mitigate these destructive floods, potentially boosting agricultural output by allowing for more stable cultivation, especially given that much of Sudan's arable land remains underutilized. Another major draw is the potential to import cheap, renewable electricity from Ethiopia, helping to address Sudan's own energy needs. The regulated water flow could also facilitate the expansion of irrigated agriculture. Furthermore, the GERD is expected to trap large amounts of sediment originating from the Ethiopian highlands. This could reduce the costly burden of sediment accumulation in Sudan's own reservoirs (Roseires, Sennar, and Merowe), potentially extending their operational lifespan and reducing the need for frequent dredging of irrigation canals.
5.2 Risks and Worries
Despite these potential upsides, Sudan harbors serious concerns. Foremost among these is dam safety. Located just 20-40km downstream from the GERD, Sudan would face catastrophic consequences in the event of a structural failure. Modeling studies commissioned in Egypt predict that a breach of the GERD could trigger the collapse of Sudan's Roseires and Sennar dams and lead to the complete inundation of Khartoum, with flood waves reaching immense heights and velocities. These fears are compounded by a perceived lack of transparency and data sharing from Ethiopia regarding the dam's design, construction quality, and safety protocols.
Operational coordination is another major worry. The safe operation of Sudan's own dams depends heavily on predictable inflows from the Blue Nile. Uncoordinated filling or sudden large releases of water from the GERD, particularly during periods of heavy rainfall or flood management operations upstream, could overwhelm Sudan's downstream infrastructure, potentially causing damage or even failure. This necessitates a clear agreement on operating rules and real-time data exchange, which has yet to materialize. Sudan also shares concerns with Egypt regarding water availability, especially during the GERD's filling phases and potential future droughts, emphasizing the need for a binding agreement on managing water flows under various hydrological conditions. Beyond the dams, potential negative environmental and socio-economic impacts along the Blue Nile and main Nile within Sudan are also a concern, affecting traditional floodplain agriculture, river ecosystems, and the livelihoods of communities dependent on the river's natural cycle. The trapping of nutrient-rich silt behind the GERD, while benefiting dam longevity, could negatively impact agricultural lands downstream that have historically relied on this natural fertilization, potentially forcing a costly transition to artificial fertilizers.
5.3 Sudan's Changing Role and Internal Conflict
Historically, Sudan's position on the GERD has vacillated. At times, particularly under the transitional civilian government (2019-2021), Khartoum appeared more receptive to the dam's potential benefits and leaned towards cooperation with Ethiopia. At other times, especially under military leadership aligned with Cairo, Sudan has emphasized the risks and echoed Egypt's demands for a binding agreement and guarantees regarding water shares and dam safety. Sudan was a signatory to the 2015 Declaration of Principles alongside Egypt and Ethiopia.
This already complex balancing act has been completely upended by the devastating civil war that erupted in April 2023 between the Sudanese Armed Forces (SAF), led by General Abdel Fattah al-Burhan, and the paramilitary Rapid Support Forces (RSF), led by Mohamed Hamdan Dagalo "Hemedti". The conflict has plunged Sudan into a catastrophic humanitarian crisis, fragmented the country, and crippled the state's ability to function, let alone engage effectively in complex regional negotiations like those concerning the GERD. Preoccupied with its existential struggle against the RSF, the SAF government in Port Sudan lacks the capacity and political bandwidth to maintain a firm or consistent stance on the dam.
The war has also introduced dangerous proxy dynamics into the GERD equation. Egypt is a key backer of the SAF and General Burhan, while Ethiopia (along with the UAE) is widely reported to support the rival RSF. This alignment further complicates any potential for a unified downstream position and risks intertwining the GERD dispute with the Sudanese civil war, potentially fueling wider regional instability. The conflict has effectively nullified the previous Egypt-Sudan security cooperation that had aimed, in part, to exert pressure on Ethiopia regarding the dam. Despite the internal chaos, remnants of Sudan's concerns persist. In November 2024, Sudan's Acting Foreign Minister publicly suggested that Sudan could side with Egypt and warned of the possibility of war if a tripartite agreement ensuring water rights was not reached, prompting a formal protest from Addis Ababa. This highlights the enduring anxieties in Khartoum, even amidst the turmoil.
The Sudanese civil war has significantly altered the hydro-political landscape of the Nile basin. By effectively neutralizing Sudan as a coherent actor in the GERD negotiations, the conflict has inadvertently strengthened Ethiopia's position, allowing it to proceed with unilateral actions like the fifth filling with less coordinated downstream resistance. It has weakened Egypt's diplomatic leverage by removing its primary downstream ally and created a volatile situation where Ethiopia might seek to exploit Sudan's internal divisions to further its own interests regarding the dam. This makes the already difficult prospect of reaching a sustainable three-party agreement even more challenging in the current context.
6. Failed Negotiations
Despite the clear need for cooperation in managing a shared, vital resource, the decade following the GERD's launch has been marked by a frustrating cycle of negotiations, temporary agreements, and ultimate deadlock. Numerous rounds of talks involving the three primary riparian states – Egypt, Ethiopia, and Sudan – and various international mediators have failed to produce a comprehensive and lasting agreement on the dam's filling and operation.
6.1 A Timeline of Talks
Efforts to establish cooperative frameworks for the Nile predate the GERD. The Nile Basin Initiative (NBI), launched in 1999, brought together riparian states with the goal of fostering joint development, sharing socioeconomic benefits, and promoting regional peace. It aimed to create a shared vision and policy guidelines for basin-wide action, implementing programs focused on confidence-building, data sharing, and sub-basin investments. However, the NBI's attempt to create a permanent legal framework, the Cooperative Framework Agreement (CFA) or Entebbe Agreement in 2010, faltered. While signed by several upstream countries promoting the principle of "equitable and reasonable utilization," Egypt and Sudan rejected it, arguing it failed to adequately protect their "historical rights" and water security based on the 1929 and 1959 agreements. This fundamental split undermined the NBI's potential and foreshadowed the difficulties ahead.
Following the GERD's launch in 2011, initial trilateral technical meetings were held. An International Panel of Experts (IPoE), comprising representatives from the three countries and international experts, was established to assess the dam's impacts. The IPoE's 2013 report found no fundamental flaws but recommended further detailed studies on downstream hydrological and environmental impacts. A significant diplomatic step occurred in March 2015 with the signing of the Declaration of Principles (DoP) in Khartoum. This agreement outlined broad principles for cooperation, including equitable and reasonable use, the obligation not to cause significant harm, data exchange, and the commitment to agree on guidelines for the GERD's first filling and annual operation.
However, translating these principles into practice proved elusive. The subsequent years (2015-2019) saw talks stall repeatedly over the methodology and execution of the impact studies mandated by the DoP, with disagreements arising over baseline scenarios, particularly Egypt's insistence on using its "existing use" as the reference point. Multiple negotiation rounds failed to bridge the gaps.
Seeking external impetus, the United States and the World Bank stepped in as observers and facilitated intensive negotiations in Washington D.C. in late 2019 and early 2020. This effort collapsed when Ethiopia withdrew, refusing to sign a draft agreement prepared by the observers, which it viewed as biased towards downstream interests and exceeding the observers' mandate. The subsequent decision by the Trump administration to cut aid to Ethiopia further damaged trust and undermined the US role as an impartial mediator.
Following Egypt's appeal to the UN Security Council (UNSC) in mid-2020 and Ethiopia's commencement of the first filling, the African Union (AU) took the lead in mediating the dispute. Several rounds of virtual negotiations were held under the chairmanship of South Africa, then the DRC. However, these talks also became bogged down in procedural issues, disagreements over the role of observers, and the core substantive sticking points. A proposal by Egypt and Sudan for a quadripartite mediation involving the AU, UN, EU, and US was rejected by Ethiopia, which preferred the AU-led process. In September 2021, the UNSC adopted a Presidential Statement encouraging the parties to resume the AU-led negotiations expeditiously to finalize a mutually acceptable and binding agreement. Despite this, the AU-led process yielded little tangible progress and has often been criticized as lacking effectiveness or sustained engagement.
A brief flicker of hope emerged in July 2023 when the leaders of Egypt and Ethiopia met and agreed to restart negotiations with a four-month deadline to reach an agreement. However, the final round of these talks collapsed again in December 2023. Egypt subsequently declared the negotiation track futile under the existing conditions and announced its withdrawal. While the United Arab Emirates reportedly hosted some discreet technical discussions during this period, the formal diplomatic process remains frozen as of early 2025. Egypt's recent strong rejection of a proposed site visit to the GERD during an NBI event in Addis Ababa underscores the depth of the current impasse.
6.2 Key Disagreements
Throughout the decade of negotiations, several key issues have consistently prevented an agreement:
Nature of the Agreement: Egypt and Sudan insist on a comprehensive, legally binding treaty covering both the initial filling and the long-term annual operation of the GERD, enforceable under international law. Ethiopia has resisted this, preferring potentially less rigid "guidelines" or arrangements that it feels better preserve its sovereignty and flexibility for future water resource management.
Drought Management Rules: This is perhaps the most critical technical and political hurdle. Disagreements persist on how to define drought conditions (single dry year vs. multi-year drought) and, crucially, how the burden of water scarcity should be shared. Egypt and Sudan demand specific guarantees that Ethiopia will release predetermined volumes of water from the GERD reservoir during droughts to mitigate downstream impacts, effectively asking Ethiopia to prioritize downstream needs over its own hydropower generation. Ethiopia is unwilling to accept fixed release obligations that could cripple the dam's primary function.
Dispute Resolution Mechanism: The parties disagree on how future conflicts over the interpretation or implementation of any agreement should be resolved. Egypt and Sudan typically advocate for compulsory, binding third-party arbitration, while Ethiopia favors mechanisms that involve consultation and negotiation, potentially escalating to non-binding mediation, wary of external mechanisms infringing on its sovereignty.
Data Sharing and Notification: While the principle of data sharing is generally accepted (and included in the DoP), establishing trusted mechanisms for timely and transparent exchange of hydrological data and operational plans remains a challenge, hampered by mutual suspicion.
Future Upstream Development: Egypt and Sudan seek clarity and potentially some form of consultation or limitation on Ethiopia's future water development projects upstream of the GERD. Ethiopia views such demands as an unacceptable constraint on its sovereign right to develop its own natural resources.
Status of Historical Agreements: Underlying many of these issues is the unresolved conflict over the relevance of the 1929 and 1959 agreements. Egypt and Sudan implicitly or explicitly seek to protect the water volumes associated with their "acquired rights" under those treaties, while Ethiopia rejects their validity and bases its claims on equitable utilization.
6.3 Why Talks Failed
The persistent failure to reach an agreement stems from a confluence of factors:
Profound Mistrust and Lack of Political Will: Decades of hydro-political tension have created deep-seated mistrust among the parties. Leaders have often appeared unwilling to make the necessary compromises, sometimes seeming to prioritize domestic political posturing or using negotiations as a delaying tactic rather than genuinely seeking a mutually acceptable solution.
Conflicting Paradigms and Zero-Sum Perceptions: The negotiations are hampered by fundamentally different national objectives – Egypt prioritizing the preservation of its historical water share for survival, Ethiopia prioritizing sovereign development through hydropower. This, combined with the historical context, fosters a zero-sum perception where one party's gain is seen as the other's loss.
Securitization and Nationalism: All sides have, at times, framed the GERD issue in highly nationalistic and security-focused terms. Egypt portrays the dam as an existential threat, while Ethiopia presents it as a non-negotiable symbol of national sovereignty and renaissance. This rhetoric mobilizes domestic support but severely limits leaders' diplomatic flexibility.
Ineffective Mediation: External mediation efforts, whether by the US, World Bank, or AU, have struggled to overcome these fundamental obstacles. Mediators have faced challenges related to perceived bias, insufficient leverage, or an inability to bridge the core conceptual divides between the parties. The AU-led process, in particular, has been seen by some participants and observers as lacking the necessary political weight or consistent engagement to force progress.
Geopolitical and Domestic Complexities: The dispute does not exist in a vacuum. It is intertwined with broader regional rivalries, the competing interests of external powers in the Horn of Africa and Red Sea region, and the internal political dynamics and instability within each country, most notably the ongoing civil war in Sudan.
Ultimately, the negotiation deadlock reflects a clash far deeper than technical disagreements over flow rates or drought thresholds. It represents a fundamental conflict between Egypt's defense of a hydro-political status quo rooted in historical allocations and its perceived vulnerability, and Ethiopia's assertion of its sovereign right to development based on contemporary principles of equitable utilization. This clash is amplified by profound mistrust and potent nationalist narratives on all sides. Ethiopia's successful construction and ongoing unilateral operation of the GERD have created irreversible facts on the ground, strengthening its negotiating position and making it less likely to concede to downstream demands for restrictive controls. Without a fundamental shift in these underlying paradigms, the diplomatic stalemate is likely to persist.

7. The Legal Dispute
The dispute over the GERD is not only political and technical but also deeply legal, involving conflicting interpretations of historical treaties and modern principles of international water law. While legal frameworks exist, their application to the Nile is contested, creating a complex legal battleground where each state seeks justification for its position.
7.1 International Water Law
Several core principles of customary international law are relevant to disputes over shared transboundary watercourses like the Nile:
Equitable and Reasonable Utilization (ERU): This is widely considered the cornerstone principle. It obliges states sharing an international watercourse to use the waters within their territory in a manner that is equitable and reasonable vis-à-vis other basin states. Determining what is equitable and reasonable involves considering a range of factors, including the geography and hydrology of the basin, the climate, the population dependent on the waters, existing and potential uses, the availability of alternative resources, the potential impacts of planned uses, and the conservation and economy of water resource use. This principle generally supports Ethiopia's right to develop the Blue Nile's hydropower potential, provided it considers the impacts on downstream states.
Obligation Not to Cause Significant Harm (NCSH): This principle requires states to exercise due diligence to prevent activities within their jurisdiction from causing significant harm to other states sharing the watercourse. Egypt frequently invokes this principle, arguing that the GERD threatens significant harm to its water security. A key point of contention is the definition of "significant harm." Downstream states may interpret any reduction in historical flow levels as significant, while upstream states and some legal interpretations link it more closely to impacts on essential human water requirements or severe environmental damage. There can also be tension between ERU and NCSH, particularly if an existing use (potentially protected by NCSH) is deemed inequitable under ERU.
Duty to Cooperate: International law imposes a general obligation on states sharing a watercourse to cooperate in good faith regarding its use, development, and protection. This includes duties such as providing prior notification of planned measures that may have significant adverse effects, exchanging data and information regularly, and engaging in consultations and negotiations to address potential disputes.
These customary principles are largely codified in the 1997 United Nations Convention on the Law of the Non-Navigational Uses of International Watercourses (UNWC). While the UNWC provides a comprehensive framework, its direct legal force in the Nile dispute is limited because Egypt, Ethiopia, and Sudan have not ratified it. Nevertheless, its provisions, particularly those reflecting ERU and NCSH, are often cited as evidence of customary international law. Notably, the UNWC explicitly moves away from prioritizing historical or customary use in favor of achieving equitable and reasonable utilization among all riparian states.
Adding another layer of legal complexity are the conflicting theories of state succession regarding colonial-era treaties. As mentioned earlier, Ethiopia adheres to the Clean Slate theory, arguing it is not bound by the 1902, 1929, or 1959 agreements signed by colonial powers or without its participation. Egypt tends towards the Continuity theory, asserting the enduring validity of these agreements, particularly regarding its acquired water rights.
7.2 Conflicting Legal Arguments
The ambiguity and non-binding nature of parts of the legal framework allow each state to construct legal arguments supporting its national interests:
Egypt's Argument: Egypt's legal case rests heavily on its interpretation of "historical" or "acquired rights" derived primarily from the 1929 and 1959 agreements, which granted it the lion's share of the water and veto power. It interprets the principle of "no significant harm" broadly, contending that any unilateral action by Ethiopia that reduces water flow below historically established levels constitutes significant harm, given Egypt's extreme water dependency and vulnerability. Cairo views Ethiopia's unilateral filling and operation of the GERD as a material breach of the 2015 Declaration of Principles (which called for agreement prior to operation) and a violation of international law principles requiring prior consent and avoidance of harm.
Ethiopia's Argument: Ethiopia firmly rejects the validity of the colonial-era treaties that excluded it. Its legal position is anchored in the principle of Equitable and Reasonable Utilization, asserting its sovereign right to develop the hydropower potential of the Blue Nile within its territory for economic development and poverty alleviation. Addis Ababa argues that the GERD, being a hydropower dam, is primarily non-consumptive and will not cause "significant harm" to downstream countries, potentially even offering benefits like flood control and regulated flow. It interprets "significant harm" more narrowly, likely focusing on the protection of basic human needs downstream, consistent with some interpretations of the UNWC. Ethiopia views downstream demands for a binding agreement dictating its dam operations as an infringement on its sovereignty and argues that the DoP acknowledged the GERD's purpose and did not explicitly forbid filling before a final agreement.
Sudan's Legal Position: Sudan's legal stance has been less consistent, reflecting its intermediate position and fluctuating political alignments. It sometimes emphasizes the potential benefits accruing from the GERD under ERU principles (flood control, power) while at other times voicing strong concerns about dam safety and operational impacts, aligning with Egypt's calls for a binding agreement based on NCSH and the need for cooperation.
This divergence highlights a critical issue: international water law, while providing important principles, lacks definitive, universally accepted rules for precise water allocation or universally binding enforcement mechanisms, especially when foundational treaties are contested and key conventions remain unratified by the disputing parties. The principles themselves are broad and require interpretation based on specific circumstances, allowing states to selectively emphasize those that favor their interests. The 2015 DoP, intended as a bridge, has itself become subject to conflicting interpretations. This legal ambiguity creates space for political maneuvering and ensures that the dispute cannot be resolved solely through legal arguments; political negotiation and compromise remain essential.
7.3 Basin-Wide Cooperation Efforts
The Nile Basin Initiative (NBI), established in 1999, represented a significant effort to move towards cooperative, basin-wide management. It aimed to build trust, share information, develop joint projects, and ultimately create a permanent legal and institutional framework. This culminated in the drafting of the Cooperative Framework Agreement (CFA), finalized in Entebbe, Uganda, in 2010. The CFA sought to replace the old bilateral agreements with a new regime based on principles like equitable and reasonable utilization, the obligation not to cause significant harm, and prior notification.
However, the CFA process ultimately failed to achieve basin-wide consensus. Egypt and Sudan refused to sign, primarily due to objections concerning Article 14b, which dealt with water security. They felt the article did not sufficiently guarantee their existing water uses and historical rights as enshrined in the 1929 and 1959 agreements. Upstream countries, including Ethiopia, proceeded to sign the CFA without Egypt and Sudan, deepening the divisions within the basin. Egypt subsequently suspended its participation in NBI technical activities. This failure to agree on a new, inclusive legal framework under the NBI highlighted the enduring power of the historical hydro-political fault lines. It demonstrated the immense difficulty of establishing cooperative institutions when fundamental disagreements over the basis of water rights – historical allocation versus equitable utilization – remain unresolved. The GERD dispute arose, in part, because this prior attempt to establish agreed-upon rules for development and water sharing had failed to secure the buy-in of the key downstream states. Recent diplomatic activity in early 2025 suggests renewed efforts might be underway to revise the CFA text to achieve consensus, potentially offering a future path for basin-wide cooperation if successful.
8. The Future Outlook
As the Grand Ethiopian Renaissance Dam transitions from construction project to operational reality, the Nile basin stands at a critical juncture. The diplomatic deadlock persists, regional instability adds layers of complexity, and the impacts of climate change loom large. The future trajectory of the dispute remains highly uncertain, with potential pathways ranging from eventual cooperation to dangerous escalation.
8.1 Where Things Stand Now
The physical reality of the GERD is now largely established. Ethiopian authorities declared the dam's construction 100% complete in October 2024. The fifth and likely final major filling phase was completed in late 2024, bringing the reservoir close to its operational capacity, holding an estimated 60-64 BCM of water. At least four, and possibly up to six, of the thirteen turbines have been installed and have generated power, although reports suggest their operation may be intermittent rather than continuous. The dam is, for all practical purposes, a "fait accompli".
Diplomatically, however, the situation remains frozen. Formal negotiations collapsed in December 2023, and Egypt officially considers that negotiation track closed. Rhetoric remains tense. Egypt continues to protest Ethiopia's unilateralism at international forums like the UN Security Council, framing the dam as an existential threat and reserving its right to act. Ethiopia dismisses these claims, reiterates the dam's benefits, rejects external interference, and insists on its sovereign rights. The rejection by Egypt of a proposed GERD visit during an NBI ministerial meeting in February 2025 highlights the ongoing acrimony and lack of trust.
Regarding immediate impacts, the catastrophic water shortages feared by Egypt during the filling period have not yet fully materialized. This may be partly attributable to several consecutive years of relatively high rainfall in the Blue Nile basin, which helped replenish the Aswan High Dam reservoir even as the GERD was being filled. However, Egypt did report a noticeable one-month delay in the arrival of the annual Nile floodwaters following the completion of the fifth filling in 2024, indicating tangible downstream effects. Deep concerns persist about the potential impacts during future periods of drought or low rainfall, scenarios for which no agreed management plan exists.
8.2 The Impact of Sudan's War
The ongoing civil war in Sudan significantly complicates the GERD dispute and regional stability. The conflict has effectively paralyzed Sudan as a negotiating entity, removing a key, albeit often ambivalent, downstream stakeholder and weakening Egypt's diplomatic position. The war has also created dangerous proxy dynamics, with Egypt backing the SAF while Ethiopia is seen as supporting the RSF. This intertwining of the GERD issue with Sudan's internal conflict increases the risk of miscalculation and spillover, potentially drawing regional powers deeper into Sudan's tragedy. Furthermore, the chaos in Sudan serves as a major distraction for regional and international actors, allowing Ethiopia to continue consolidating the GERD's operational status with less coordinated opposition. The immense humanitarian crisis generated by the war in Sudan – the world's largest hunger and displacement crises – adds another layer of fragility to a region already stressed by water disputes.
8.3 Climate Change Effects
Climate change represents a significant threat multiplier in the Nile basin. Scientific projections indicate rising temperatures, increasingly erratic rainfall patterns, and a higher frequency of extreme events like droughts and floods. This variability will inevitably impact Nile flows, likely exacerbating existing water scarcity, particularly in downstream countries like Egypt. Increased water stress is highly likely to intensify competition for resources and heighten hydro-political risks. The unpredictability of future flows makes the lack of an agreed framework for managing the GERD (and coordinating its operation with the Aswan High Dam) during dry years even more dangerous. Reduced water availability due to climate change will also severely impact agricultural productivity throughout the basin. While the shared threat of climate change could theoretically act as a catalyst for cooperation and joint adaptation strategies, the current political climate suggests that increased scarcity is more likely to fuel competition and conflict in the absence of robust cooperative mechanisms.
8.4 Possible Scenarios
Given the complex interplay of factors, several future scenarios for the Nile dispute are plausible:
Continued Stalemate and Unilateralism: This scenario largely reflects the current trajectory. Ethiopia continues to operate the GERD according to its own priorities, without a binding agreement with downstream states. Egypt and Sudan focus on domestic water conservation measures, diplomatic protests, and potentially seek leverage through other regional or international means. Tensions remain high, flaring up periodically, especially during drought years or if downstream impacts become more severe. Mistrust persists, preventing meaningful cooperation.
Cooperative Framework Agreement: A significant diplomatic breakthrough occurs, perhaps driven by a change in leadership, effective external mediation (potentially by actors like the UAE, or a revitalized AU/UN effort), or a realization of the mutual risks of non-cooperation. This leads to a comprehensive, legally binding agreement covering long-term filling and operation rules (including detailed drought management protocols), transparent data sharing, dam safety verification, and effective dispute resolution mechanisms. This could potentially unlock significant benefit-sharing opportunities, such as optimized hydropower production and regional energy trade. However, achieving this requires overcoming deep-seated mistrust and fundamentally conflicting national positions.
Limited / Interim Agreement: Recognizing the difficulty of a comprehensive deal, the parties opt for a more limited, possibly technical, agreement focusing on specific, achievable aspects. This might include rules for annual operational coordination during normal hydrological years, enhanced real-time data exchange, and joint safety assessments, without resolving the contentious issues of long-term drought management or the legal status of historical agreements. Such a phased approach could potentially build confidence and serve as a stepping stone towards a broader settlement, but it risks leaving the most critical issues unresolved and vulnerable to future crises.
Escalation and Conflict: The diplomatic impasse, combined with a trigger event – such as a severe multi-year drought causing significant harm downstream, a major dam safety incident, a political miscalculation, or spillover from regional conflicts (like Sudan or Ethiopia-Somalia tensions) – leads to escalation. This could manifest in various forms: intensified diplomatic and economic pressure, cyber warfare, support for proxy forces in neighboring countries, border skirmishes (particularly along the disputed Ethiopia-Sudan border), or, in the most extreme (though less likely) scenario, direct military action. Warnings from leaders in Egypt, Ethiopia, and Sudan indicate that the potential for conflict, however undesirable, is not entirely dismissed.
Regional Fragmentation and Wider Instability: The ongoing collapse and potential fragmentation of Sudan could destabilize the entire region, making any form of basin-wide water management impossible. The GERD dispute could become subsumed within a broader landscape of overlapping conflicts, proxy wars, and state failure, with devastating humanitarian consequences.
The future of the Nile remains profoundly uncertain. While the physical existence of the GERD is now a reality, the political and legal framework governing its long-term operation is dangerously absent. This leaves the basin vulnerable to the vagaries of climate, the instability of regional politics, and the calculations of national leaders. The "fait accompli" nature of the dam might eventually force a more pragmatic approach focused on managing impacts rather than preventing the project itself. However, the deep historical grievances, potent nationalisms, and fundamental disagreements over water rights ensure that the path forward will be fraught with difficulty, leaving both the potential for cooperation and the risk of conflict wide open.
9. What Next for the Nile?
The Nile River, the cradle of ancient civilizations and a lifeline for modern nations, is now the stage for one of the world's most complex and potentially volatile transboundary water disputes. The conflict, centered on Ethiopia's Grand Ethiopian Renaissance Dam, is a culmination of historical grievances rooted in colonial-era water allocations that heavily favored downstream Egypt, Ethiopia's powerful drive for development and energy independence, and Sudan's precarious position caught between its upstream neighbor and downstream partner. A decade of intensive, often acrimonious, negotiations involving various mediators has failed to bridge the fundamental divides, leaving a legacy of mistrust and diplomatic deadlock. Ethiopia has proceeded unilaterally, completing the dam's construction and multiple filling phases, while Egypt continues to voice dire warnings about threats to its existential water security. The situation is further complicated by the devastating civil war in Sudan, which has destabilized the region and weakened the downstream negotiating bloc, and the looming threat of climate change, which promises to exacerbate water scarcity across the basin.
The reality today is that the GERD is operational. Arguments about whether the dam should have been built are now largely moot. The critical challenge has shifted from prevention to management. The focus must now be on establishing a cooperative framework to govern the dam's long-term operation in a way that maximizes potential benefits while mitigating risks for all parties involved. This requires a fundamental shift away from the zero-sum calculations and nationalist rhetoric that have characterized the dispute thus far.
