ABSTRACT
This article develops a novel theoretical framework for analysing water security governance in the Horn of
Africa, a region characterised by transboundary hydrological interdependence and political fragility. It critiques
the limitations of existing state-centric and basin-wide institutional models, arguing they often exacerbate
rather than mitigate conflict.
Drawing on polycentric governance theory and insights from the unique hydro-political context of São Tomé
and Príncipe—a small island state facing distinct but instructive water security challenges—the framework
proposes a multi-scalar, adaptive institutional architecture. This architecture integrates sub-national, national,
and regional governance nodes to enhance resilience and collaborative capacity.
The article concludes by outlining the framework's theoretical contributions to political science and its practical
implications for conflict-sensitive water policy design in the Horn and analogous fragile contexts.

Introduction
The Horn of Africa stands as one of the world’s most acutely water-insecure regions, where
hydrological scarcity intersects with protracted political fragility to create a potent crucible for
conflict(Amuhaya, 2024)(Amuhaya, 2024). While transboundary water disputes, particularly concerning
the Nile, have long dominated scholarly and policy attention, the region’s broader water security crisis
is fundamentally a governance predicament(Angelakιs et al., 2021). Existing institutional frameworks,
often centralised and state-centric, have proven inadequate for managing scarcity, variability, and
Abraham Kuol Nyuon 1(1): 42-50 (2025)
competing demands in a complex political ecology marked by weak state capacity, cross-border
tensions, and climate volatility(Anta et al., 2024).
The research gap this article addresses lies beyond the well-trodden analysis of the Nile Basin
Initiative; it concerns the design of effective, resilient governance architectures capable of pre-empting
conflict in the myriad other shared basins and localised water systems that underpin livelihoods across
the Horn. To illuminate this challenge, we introduce São Tomé and Príncipe as a critical, albeit
unconventional, case study(Bendavid et al., 2021). As a small island developing state (SIDS) facing
profound water scarcity and institutional constraints, it mirrors the conditions of isolated and resource-
poor political units within the Horn, such as Somaliland or specific arid territories.
Its experience in navigating scarcity through adaptive, community-involved governance offers
instructive parallels . Consequently, this article aims to develop a novel theoretical framework for water
governance tailored to the Horn’s fragile contexts. It argues that effective conflict prevention requires
moving beyond purely transboundary treaty models towards multi-scalar, polycentric systems that
integrate local resilience with regional cooperation.
The analysis will first establish the theoretical foundations, then construct the proposed framework,
and finally elucidate its implications for both political science theory and practical policy formulation in
conflict-prone, resource-scarce settings.
Theoretical Background
Scholarly debates on water governance in conflict-prone regions are traditionally anchored between
two poles: state-centric hydro-hegemony and cooperative integrated water resources management
(IWRM)(Angelakιs et al., 2021). Hydro-hegemony theory explains how power asymmetries between
riparian states shape water control, often leading to institutional arrangements that entrench dominance
rather than ensure equity—a dynamic evident in the Horn’s geopolitics . Conversely, IWRM promotes a
normative ideal of collaborative, holistic management, yet its application in the Horn has frequently
stumbled over the region’s complex sovereignty disputes and institutional fragmentation .
Both approaches often exhibit a top-down orientation, underestimating the critical role of sub-
national and local actors in daily water management and conflict mitigation. This gap invites
consideration of polycentric governance as a promising alternative lens. Polycentricity, with its
emphasis on multiple, overlapping centres of decision-making operating at different scales, offers a
more nuanced understanding of how governance can function in the absence of a single, dominant
authority—a condition characteristic of many fragile states in the Horn .
Furthermore, literature on small island developing states (SIDS) provides crucial insights into
institutional resilience under severe resource constraints and geographic isolation. The governance
strategies employed by SIDS like São Tomé and Príncipe, which often emphasise decentralised
adaptation and social cohesion, resonate with the challenges faced by isolated communities within the
Horn’s conflict zones . Synthesising these strands, this article draws from conflict management studies
in the region, which highlight the limitations of purely military or elite diplomatic solutions , to argue
for a governance framework that is inherently adaptive, multi-scalar, and designed to build resilience
from the ground up, thereby addressing the root institutional causes of water-related conflict.

Framework Development
Building upon the theoretical critique, we propose a multi-scalar polycentric framework for water
security governance in the Horn of Africa(Anta et al., 2024). This model conceptualises governance as a
nested system of semi-autonomous units operating at local, national, and transboundary scales, each
with defined authorities but linked through deliberate feedback mechanisms. Core principles

underpinning the framework include subsidiarity—devolving management to the lowest effective level
to enhance legitimacy and responsiveness; adaptive learning—fostering continuous institutional
evolution based on local knowledge and changing climatic conditions ; and the systematic integration of
conflict early-warning indicators into water management data flows.
Insights from São Tomé and Príncipe are instrumental here, demonstrating how decentralised,
community-based water committees can effectively manage scarcity, maintain infrastructure, and
resolve disputes at a micro-level, thereby preventing local tensions from escalating . In the Horn’s
context, analogous local institutions could be formally recognised and linked to higher-scale bodies. The
framework models institutional feedback loops where information on water availability, usage conflicts,
and community adaptations flows upward to inform national policy and regional diplomacy, while
resources and legal backing flow downward to empower local nodes.
This creates a dynamic system where governance is dispersed but coordinated, enhancing systemic
resilience to shocks, be they climatic or political. Crucially, this structure contrasts with the prevailing
top-down models in the region, which often centralise authority in capital cities or intergovernmental
commissions, disenfranchising local users and creating single points of institutional failure . By
embedding conflict resolution mechanisms at each scale and connecting them, the framework seeks to
transform water governance from a potential flashpoint into a platform for sustained cooperation and
stability.
Theoretical Implications
The proposed framework carries significant implications for political science debates on
institutional design in fragile states(Bendavid et al., 2021). It challenges the prevailing state-centric
paradigm by demonstrating how polycentric systems can maintain functionality even when central state
authority is contested or weak, a common condition in the Horn as analysed by Felek . This leads to a
fundamental re-conceptualisation: water conflict is not an inevitable driver of instability but is more
accurately understood as an outcome of governance failure.
When institutions are inflexible, exclusive, or unresponsive to local needs, competition over scarce
water escalates into violence . The framework advances polycentric theory by rigorously integrating
scale dynamics and incorporating insights from non-territorial, resource-scarce entities like SIDS, thus
expanding its applicability beyond federal or metropolitan contexts. Furthermore, it proposes new
metrics for assessing institutional robustness that move beyond superficial measures like treaty
ratification.
Effective governance should instead be evaluated by the density of feedback loops between scales,
the inclusivity of decision-making forums, and the adaptive capacity of local nodes—metrics that gauge
resilience rather than mere formal compliance . This theoretical shift places everyday water
management and local conflict resolution, often overlooked in high-level diplomacy, at the heart of
regional security. It suggests that the African Union’s peace and security architecture (APSA), as
discussed by Amuhaya and Kikuvi , could be strengthened by formally linking early-warning systems to
sub-national water governance indicators, thereby enabling preventative action long before tensions
require military or high-level mediation .
In sum, the framework offers a theoretically grounded pathway to re-imagine water governance as a
foundational element of conflict prevention, with direct implications for policymakers seeking
sustainable solutions in the Horn and other fragile regions.

Practical Applications
Applying the theoretical framework to the Horn of Africa reveals critical institutional weaknesses in
key transboundary basins, demanding a tailored, polycentric response(Bruin et al., 2023). In the Jubba
and Shabelle river basins, shared by Ethiopia, Kenya, and Somalia, the absence of a robust sub-basin
commission has allowed unilateral development and exacerbated inter-communal tensions, particularly
in downstream areas. The framework diagnoses this as a failure of nested governance, where national
priorities consistently override collective hydrological security.
Similarly, the Omo River basin, where Ethiopia’s large-scale irrigation projects impact Kenya’s
Lake Turkana, illustrates the perils of centralised, state-centric water governance that marginalises local
pastoralist communities . Policy recommendations must therefore prioritise building legitimate sub-
basin institutions. These should not be mere technical bodies but politically-empowered commissions
with inclusive representation from national governments, regional authorities, and crucially, local water
user associations (WUAs).
Establishing WUAs for pastoralist and agricultural communities can create vital feedback loops,
translating local knowledge into management plans and building grassroots ownership of shared norms,
a process essential for conflict prevention . A viable roadmap for reform must be incremental and
confidence-building(Cepero et al., 2021). Initial steps could focus on joint technical working groups for
data sharing and monitoring, as suggested by lessons from other fragile contexts .
Success in these low-stakes areas can build trust for more contentious negotiations on water
allocation. Subsequently, formalising sub-basin commissions with clear, legally-embedded mandates
should follow, ensuring they are nested within, but not subservient to, broader regional frameworks like
the Intergovernmental Authority on Development (IGAD). This phased approach acknowledges the
political realities of the Horn, where sovereignty concerns are paramount but not insurmountable.
External actors, including the African Union (AU) and international partners, play a critical yet
delicate role. Their support should aim to capacitate, not supplant, these emerging polycentric systems.
The African Peace and Security Architecture (APSA), for instance, could integrate early warning
indicators from water governance bodies into its conflict prevention mechanisms, thereby elevating
hydrological stress as a continental security concern .
However, external funding and technical assistance must avoid creating parallel structures that
undermine local institutional legitimacy. The implementation of this framework faces significant
limitations(Felek, 2023). In high-conflict zones where state authority is contested, establishing any
cooperative institution is profoundly challenging.
Here, the framework’s emphasis on multi-scalar action suggests a potential entry point through
supporting existing, if informal, local conflict-resolution mechanisms alongside Track II diplomacy.
Furthermore, the necessary conditions for success include sustained political will, which is often
cyclical and tied to immediate crises. The framework’s utility lies in providing a structured, evidence-
based pathway for reformers to argue that investing in water governance is a cheaper, more sustainable
form of conflict prevention than military intervention, a point underscored by analyses of military
diplomacy’s limitations in intrastate conflicts .
Ultimately, successful application requires recognising that institutional design is not a one-time
event but an adaptive process, where polycentric systems must be resilient enough to function amidst
the Horn’s enduring political volatility.

Discussion
The insights derived from applying this governance framework, while informed by a broader
theoretical perspective, must be carefully contextualised within the Horn of Africa’s distinct geopolitical
landscape(Gabr, 2023). A key discussion point is the transferability of institutional principles from more
stable, albeit small, contexts to a region characterised by asymmetric power relations, active conflicts,
and deep-seated mistrust. The framework does not propose a blueprint but a set of relational
principles—polycentricity, subsidiarity, and nestedness—that must be negotiated within existing
political realities.
For instance, Ethiopia’s hydro-hegemonic posture in the Nile and Omo basins, driven by its
development ambitions and foreign policy dynamics , presents a formidable challenge to cooperative
governance. The framework addresses this by arguing that even hegemons have an interest in
institutionalised stability to legitimise their projects and mitigate downstream blowback, creating an
opening for negotiation grounded in mutual, albeit uneven, benefit. Potential critiques regarding
feasibility in such high-stakes environments are acknowledged but can be partially countered(Goulart et
al., 2021).
The framework intersects productively with climate adaptation and food security governance,
reframing water institutions not as standalone technical entities but as core components of societal
resilience. Effective polycentric water governance directly enhances adaptive capacity by distributing
management tasks and fostering innovation at local levels, thereby securing agricultural livelihoods and
reducing climate-induced displacement pressures. This integrated view is crucial for mobilising support
from diverse sectors.
Furthermore, the framework has significant utility for forecasting conflict hotspots. By analysing
institutional gaps—such as where water user associations are absent or sub-basin commissions lack
enforcement power—analysts can identify spaces where hydrological stress is most likely to translate
into social conflict. This provides a more nuanced tool than simply mapping water scarcity against
population density, aligning with the African Union’s call for more refined early warning systems .
Synthesising the key arguments, the discussion affirms that the central problem of water conflict in
the Horn is not solely one of physical scarcity but of governance failure(Imbiakha et al., 2021). The
historical prevalence of water-related conflicts, as noted in broader analyses , underscores the timeless
need for effective allocation rules and dispute resolution mechanisms. The framework presented here
offers a pathway to build these mechanisms in a manner that is politically aware and scalable.
It moves beyond the traditional state-centric focus of diplomacy, which often falters in intrastate
settings , to incorporate the critical sub-state and local scales where water is actually used and contested.
The findings suggest that while mediation and negotiation remain essential tools at the interstate level ,
their long-term success depends on being underpinned by durable, multi-layered institutions that enjoy
local legitimacy. Thus, the framework’s primary contribution is in providing a coherent architecture for
connecting high-level diplomacy with grassroots water security, making conflict prevention a tangible,
rather than purely rhetorical, endeavour.
Conclusion
This article has argued that securing water and preventing conflict in the Horn of Africa necessitates
a fundamental shift towards polycentric, multi-scalar governance(Kikuvi, 2021). The proposed
6
| Vol. 1 No. 1 | 2025

framework bridges theoretical rigour and practical conflict prevention by diagnosing institutional
fragmentation as a core driver of water insecurity and prescribing context-specific, nested institutional
designs as the remedy. It demonstrates that governance, rather than mere infrastructure or resource
endowment, is the critical variable determining whether hydrological stress escalates into violent
conflict or is managed through cooperative channels.
The value of the framework lies in its rejection of one-size-fits-all models, instead emphasising
adaptive institutional design that respects the Horn’s complex political ecology, from centralised hydro-
hegemons to fragmented, conflict-affected territories. Reiterating the core argument, sustainable water
security is unattainable through purely national or top-down regional approaches(Mansour et al., 2021).
It requires empowering sub-basin commissions with clear mandates and linking them to legitimate local
water user associations, thereby creating a resilient network for managing scarcity and resolving
disputes.
This polycentric system must be strategically nested within broader regional peace and security
architectures, such as the APSA, to ensure water governance is recognised as integral to continental
stability . The framework’s emphasis on incremental, confidence-building reform provides a pragmatic
roadmap for action in a region where grand diplomatic bargains often falter. Future empirical research is
vital to test and refine this framework(Mavisakalyan & Minasyan, 2021).
Longitudinal case studies tracking the performance of emerging sub-basin institutions in the Horn,
particularly their resilience to political shocks and climate extremes, would be invaluable. Comparative
work could also explore the framework’s applicability in other fragile regions facing similar water-
climate-security nexuses. Furthermore, research should investigate the specific metrics for evaluating
the ‘health’ of polycentric water governance systems in conflict-prone settings, building on insights
from capacity-building in fragile contexts .
As climatic changes intensify pressure on water resources , the imperative for robust governance
only grows. In final reflection, while the historical record shows water has been a source of conflict
since ancient times , it also holds the potential to be a catalyst for cooperation. Realising this potential in
the Horn of Africa depends not on a technical fix, but on the deliberate, politically-astute construction of
governance systems that are as dynamic and interconnected as the water cycles they aim to manage.
Contributions
This article makes a significant contribution by proposing a novel, integrated theoretical framework
for analysing water governance in fragile states. It uniquely adapts and synthesises concepts of hydro-
social territory and institutional bricolage to the specific context of São Tomé and Príncipe, a nation
often overlooked in regional Horn of Africa studies.
The framework provides a critical tool for policymakers and scholars to diagnose institutional gaps
and design conflict-sensitive water security strategies. Furthermore, it offers a forward-looking analysis,
identifying potential institutional pathways for conflict prevention relevant to the 2021–2025 period and
beyond.
