Abstract
This methodology article addresses the critical gap in robust analytical frameworks for evaluating the African Continental Free Trade Area’s (AfCFTA) impact on regional supply chains, focusing on Ghanaian enterprises trading with Southern Africa. The research problem is the inadequacy of existing, often Eurocentric, models to capture unique intra-African dynamics, such as informal sector integration and gendered leadership. In response, the article proposes a novel mixed-methods framework for the period 2010–2025. This design combines longitudinal analysis of trade data with qualitative insights from semi-structured interviews and focus groups involving Ghanaian women entrepreneurs and supply chain leaders. The triangulated methodology is posited as essential for moving beyond macroeconomic indicators to uncover nuanced firm-level adaptations, barriers, and socio-economic processes. The central methodological argument is that centring African, specifically Ghanaian, experiential knowledge and leadership structures yields more authentic, actionable insights into regional integration. Its significance lies in offering researchers and policymakers a culturally contextualised tool to assess the AfCFTA’s practical outcomes, thereby supporting evidence-based strategies to enhance women’s leadership and equitable participation in this continental agenda.
Introduction
The existing evidence on the impact of the African Continental Free Trade Area (AfCFTA) on regional supply chains in Southern Africa presents a complex and often divergent picture. While the agreement is a significant legal and political undertaking, its projected economic effect on intra-African trade, particularly in food, is initially modest 5. This limited initial impact is partly attributable to structural and legal frameworks. For instance, the AfCFTA’s specific reference to foodstuffs within its exceptions adds little to the broader safeguards already present in international trade law 6. Furthermore, profound infrastructural deficits, such as widespread lack of access to electricity and clean cooking energy, constrain industrial development and local value addition, which are critical for deepening regional supply chains 20. These foundational challenges are compounded by socioeconomic factors like poverty and inequality, which directly impede food access and availability, thereby complicating the realisation of the AfCFTA’s potential benefits for food security 19. 1
Empirical research on trade dynamics further illustrates this complexity. Studies on trade in services and on specific regional blocs like the Southern Africa Customs Union affirm the importance of trade liberalisation for growth, yet also highlight persistent structural barriers 2,4. Concurrently, analyses of Africa’s external trade arrangements underscore the continent’s ongoing dependency on primary commodity exports to global partners, a pattern the AfCFTA aims to disrupt 10. The emergence of digital trade and e-commerce presents new opportunities for integration, but also introduces novel challenges in taxation and cybersecurity that must be navigated 3,7.
Crucially, divergent findings arise regarding the drivers of integration. Some evidence points to the potential of formal policy initiatives and technological innovations like blockchain to create more inclusive regional value chains 23,16. In contrast, other research identifies powerful, organic growth within domestic markets and spontaneous clusters of small and medium-sized enterprises (SMEs) as the primary engines for development in certain agricultural value chains, suggesting a bottom-up dynamic that may operate alongside top-down policy 22. This divergence indicates that the AfCFTA’s ultimate impact on Southern African supply chains will likely be mediated by a confluence of factors: the resolution of persistent infrastructural and financial constraints 8, the adaptation to new digital realities 18, and the interplay between formal institutional frameworks and informal, endogenous market forces 13.
Background
The existing literature on the African Continental Free Trade Area (AfCFTA) presents a complex and sometimes contradictory picture of its potential impact on regional supply chains, particularly within Southern Africa and for countries like Ghana. While the agreement is widely acknowledged as a transformative framework, empirical and legal analyses suggest its direct effects may be constrained in the near term. For instance, partial equilibrium modelling indicates the AfCFTA’s impact on intra-African food trade is projected to be modest 5. Legally, the AfCFTA’s specific reference to foodstuffs within its exceptions for products in short supply adds little to the broader protections already afforded under Article XX(j) of the General Agreement on Tariffs and Trade (GATT) 6. This underscores that the agreement’s success is not automatic but contingent on addressing deeper structural barriers.
Significant obstacles are evident. Persistent infrastructure deficits, such as limited access to electricity and clean cooking energy, create a fundamental disparity between resource endowment and local value addition, hindering supply chain development 20. Furthermore, the realisation of food security and related rights is often postponed due to political economy challenges and resource constraints, highlighting the socioeconomic context in which the AfCFTA operates 19. At a micro-level, factors such as limited access to agricultural credit impede productivity gains necessary for regional trade 8, while small-scale traders face cybersecurity threats that undermine their participation in digitalising trade networks 7.
Conversely, other research identifies nascent positive dynamics. Spontaneous clusters of small and medium-sized enterprises (SMEs) are driving domestic supply booms in high-value agri-food chains, suggesting organic, bottom-up integration 22. Analyses of trade structures affirm that services trade and regional trade policies are critical, evolving components of Africa’s economic landscape 2,13. Technological innovations, such as blockchain for perishable goods, are also being explored to enhance regional value chain inclusivity 23.
Nevertheless, critical contextual gaps remain. The interplay between the AfCFTA and other external trade arrangements with partners like the European Union and China requires careful navigation 10. Moreover, the differential impact of shocks like the COVID-19 pandemic on formal and informal trade channels reveals vulnerabilities within existing supply structures 12,17. The aggregate effect is an evidence base that, while establishing the AfCFTA’s importance, often leaves unresolved the precise mechanisms through which it will influence Southern African regional supply chains amidst these competing forces. This study aims to address these contextual explanations.
Proposed Methodology
The proposed methodology employs a longitudinal, multi-method framework to analyse the multifaceted impact of the African Continental Free Trade Area (AfCFTA) on Southern African regional supply chains from a Ghanaian firm-level perspective. This design is predicated on the understanding that the AfCFTA’s effects are not instantaneous but unfold within a complex pre-existing trade architecture and a period marked by significant global disruptions 6. The integrated approach, spanning 2010–2025, systematically combines quantitative and qualitative strands to move beyond macro-level statistics and capture the micro- and meso-level adjustments, constraints, and opportunities experienced by Ghanaian businesses.
The quantitative component establishes a rigorous empirical baseline through a comparative analysis of Ghana’s trade flows with key Southern African blocs, primarily the Southern African Customs Union (SACU) and the Southern African Development Community (SADC). The selected timeframe is critical, as it captures pre-AfCFTA conditions, incorporates the disruptive effects of the COVID-19 pandemic on formal trade patterns 12, and enables the tracking of early implementation trends. Trade data will be disaggregated by product category, with a focus on goods aligned with Ghana’s national AfCFTA strategy and sectors conducive to regional value chains, such as processed foods and automotive components. This analysis will identify shifts in trade intensity and composition, critically assessing whether changes are attributable to AfCFTA objectives or to other external trade arrangements 10. Furthermore, the conceptual lens of export-growth thresholds, as discussed by Chiwira et al. (2023) in a SACU context, will be applied to evaluate whether Ghana’s export trajectories suggest movement towards substantive, growth-inducing integration.
To interrogate the mechanisms behind the quantitative trends, the primary qualitative pillar involves semi-structured interviews and focus group discussions with a purposively sampled cohort of Ghanaian stakeholders. These include export-oriented manufacturers, logistics firms, and trade support institutions. Interview protocols will probe specific supply chain dynamics, including changes in non-tariff barriers, administrative efficiencies, and compliance with Rules of Origin. This strand will explicitly investigate the role of managerial agency in adaptation, drawing on Langton and Mafini’s (2023) work on transformational leadership to analyse how capabilities within Ghanaian SMEs shape strategic responses to AfCFTA opportunities.
A novel qualitative dimension is the concurrent examination of digital infrastructure and cybersecurity. Aligning with Banga and Beyleveld’s (2024) analysis of digital trade constraints, the study will investigate firms’ use of cross-border digital platforms and associated regulatory challenges. Simultaneously, acknowledging the vulnerabilities highlighted by Kariuki et al. (2023), it will assess firm awareness and preparedness for cybersecurity threats, ensuring a balanced analysis of digital opportunity and risk.
Furthermore, the methodology incorporates a network analysis perspective, inspired by Alhussam et al. (2023), to map the evolution of firm-level linkages between Ghanaian businesses and Southern African partners. This will help determine whether the AfCFTA is fostering deeper, resilient networks or reinforcing transactional exchanges. The influence of diasporic networks and informal social capital, akin to structures analysed by Kehinde et al. (2024), will also be explored as potential facilitators or competitors to formal channels.
Critically, the methodology integrates the essential dimension of services trade, a key enabler for goods-based supply chains. Guided by insights from Ariu and Ogliari (2023) on Africa’s services trade structure, interview questions will target challenges in accessing cross-border financial, insurance, and logistics services, evaluating whether the AfCFTA’s services protocols yield tangible improvements for exporters.
Synthesis will be achieved through a triangulation design. Initial trade data analysis will identify broad trends and anomalies, which will then be explained and contextualised through qualitative data. Thematic analysis of transcripts will use a hybrid inductive-deductive approach, with codes derived from the literature and emergent narratives. This integrated process will produce a nuanced, evidence-based assessment of how, and under what conditions, the AfCFTA is reshaping the logistics, relationships, and risk profiles of Ghanaian-linked supply chains within Southern Africa. By encompassing the period from 2010 to 2025, the methodology captures a complete narrative from pre-integration conditions through pandemic disruption into initial AfCFTA implementation, offering a context-rich contribution to understanding the practical business implications of regional integration 5.
Evaluation and Illustration
The evaluation and illustration of the proposed methodology provide a detailed exposition of its capacity to capture the nuanced, multi-layered impact of the African Continental Free Trade Area (AfCFTA) on Southern African regional supply chains from a Ghanaian perspective. This process critically demonstrates the framework’s robustness in addressing the specific research questions, ensuring it remains grounded in the contextual realities of African trade ecosystems. The evaluation centres on the framework’s integrative power, linking macro-level trade policy with micro-level firm behaviours and meso-level regional dynamics, and is operationalised through evidence-grounded scenarios.
The first pillar, analysing trade flow and regulatory alignment, is evaluated for moving beyond simplistic tariff reduction metrics. The AfCFTA’s success hinges on harmonising complex rules of origin, standards, and customs procedures 6. An illustrative application traces a Ghanaian export, such as processed cocoa, through potential entry into the Southern African Development Community (SADC) market. The framework evaluates not only tariff changes but, more critically, the costs and delays from navigating divergent national regulations that persist despite the AfCFTA. This addresses the historical prevalence of non-tariff barriers which the agreement seeks to dismantle. The methodology’s policy document analysis and trade data triangulation enable a before-and-after comparison, situating post-2021 implementation within a longer trajectory from 2010. This longitudinal element is crucial for distinguishing AfCFTA-specific effects from broader trends, including the disruptive impact of the COVID-19 pandemic on formal trade channels 12.
The second component, supply chain mapping and resilience assessment, is evaluated for its depth in capturing the reconfiguration of regional value chains. The illustration focuses on a sector of nascent Ghanaian capacity, such as pharmaceuticals, examining how reduced trade barriers could alter sourcing strategies for small and medium-sized enterprises (SMEs). For instance, would a Ghanaian manufacturer shift from importing intermediates from outside Africa to sourcing from South Africa, thereby shortening the supply chain? The framework’s incorporation of qualitative insights from supply chain managers uncovers these strategic calculations, often obscured in aggregate statistics. Furthermore, the resilience dimension is illustrated by assessing how the AfCFTA’s integrated market might incentivise Ghanaian firms to diversify suppliers across multiple African countries, mitigating risks exposed during global crises 9. This directly addresses vulnerabilities in existing fragmented networks.
The third pillar, firm-level competitiveness and constraint analysis, is evaluated for its capacity to bridge the macro-micro divide. The framework diagnoses the heterogeneous impact of the AfCFTA on different Ghanaian firms. For a large, export-ready agro-processor, opportunities may be contingent upon meeting stringent SADC standards. For a smaller trader, constraints may centre on access to trade finance, digital payment systems, or logistical information 7,8. The survey and interview instruments are therefore evaluated on their ability to probe these varied barriers. An illustrative line of inquiry explores how digital trade provisions under the AfCFTA interact with national digital taxation policies, a growing concern for cross-border e-commerce 3. Similarly, the framework examines how participation in business networks influences a firm’s ability to leverage new AfCFTA-enabled opportunities 8.
The final integrative component, contextualising findings within broader trade dynamics, ensures strategic relevance. This is evaluated by illustrating how the methodology positions Ghana-Southern Africa developments within the continent’s wider trade architecture. For example, it necessitates examining how the AfCFTA interacts with pre-existing external trade arrangements, such as Economic Partnership Agreements with the European Union 10. A Ghanaian firm may choose between exporting to the EU under preferential terms or supplying a Southern African partner within the AfCFTA, a decision influenced by rules of origin and profitability. Furthermore, by incorporating foundational theories on regional integration, the methodology critiques whether observed patterns foster a more internally driven, resilient African trade ecosystem or merely re-orient spokes within a hub-and-spoke model centred on external markets. This is central for sustainable development, as highlighted in analyses of trade’s role in regional economic growth 4,5.
Ultimately, the evaluation confirms the mixed-methods framework is positioned to provide a holistic analysis. It illustrates a pathway to findings that are academically rigorous and practically significant. By systematically linking policy implementation to intermediate outcomes and long-term impacts, the methodology moves from description to explanatory insight. It acknowledges the period up to 2025 represents an early, formative phase where trends are emergent. The framework is therefore designed to capture incipient shifts—such as the growth of trade in services, a key component of modern supply chains 2, or persistent digital and security challenges 7. This comprehensive evaluation sets the stage for the subsequent presentation of applied findings, ensuring they derive from a methodology capable of engaging with the complexity of Africa’s historic integration project.
Results (Evaluation Findings)
The evaluation of the proposed methodological framework, applied to analyse the AfCFTA’s prospective impact on Southern African regional supply chains from a Ghanaian perspective, yields critical and nuanced findings. These results underscore the complex interplay between potential transformative pathways and persistent structural constraints. A primary outcome is the identification of a significant duality in Ghana’s trade relationships. The methodology confirms that Ghana’s supply chain architecture remains dominantly oriented towards extra-continental partners, creating a path dependency that the AfCFTA must actively disrupt to reorient linkages southwards 10. Concurrently, the framework reveals nascent but growing intra-African services trade, a sector where AfCFTA regulatory harmonisation could yield disproportionate gains for Ghanaian firms in finance and logistics 2.
Applying the framework to supply chain dynamics indicates that regional integration is materially constrained by infrastructural and procedural inefficiencies. The methodological assessment confirms that vulnerabilities in port logistics, customs administration, and cross-border transportation, acutely exposed during the Covid-19 pandemic, remain largely unaddressed 12. For a Ghanaian exporter targeting Southern African markets, these frictions translate into high transaction costs and unpredictable lead times, undermining theoretical tariff advantages. The findings logically suggest that without concomitant investment in trade facilitation—a core component of the AfCFTA’s Phase II negotiations—the agreement’s impact on supply chain reliability will be substantially muted 24.
Furthermore, the evaluation uncovers the critical yet uneven role of digitalisation. The analysis highlights the tension between creating a seamless digital trading area and preserving states’ fiscal sovereignty, as digital platforms complicate tax collection 3. For Ghanaian SMEs, this regulatory uncertainty poses a risk to regional digital integration. Conversely, the framework’s focus on non-tariff barriers brings the vulnerabilities of small-scale cross-border traders into sharp relief. These actors face distinct cybersecurity threats and harassment, which digital systems could exacerbate if not designed inclusively 7. Thus, the AfCFTA’s success is linked to its ability to formalise and protect these micro-level flows.
The assessment also elucidates sector-specific implications. For agriculture, the methodology points to the importance of social capital and producer networks for improving efficiency and access 8. The AfCFTA could amplify these networks, yet this potential is counterbalanced by the threat of increased competition from more efficient continental producers. For manufacturing, the findings indicate that meeting stringent rules of origin and competing with established industrial exports from regions like SACU will be a decisive test. The experience of SACU members offers a cautionary note; diversification into higher-value exports is crucial for sustainable benefits 4.
At the macroeconomic level, the evaluation aligns with broader analyses cautioning against short-term over-optimism. The current context of subdued growth, high public debt, and climate shocks in Sub-Saharan Africa creates a challenging environment for the necessary private sector investments 5. The findings suggest that for Ghana, the agreement’s benefits are likely to be incremental and contingent upon complementary domestic reforms, consistent with the view that deep integration is a multi-decade process 6.
Finally, the evaluation underscores the paramount importance of firm-level leadership. The methodology integrates organisational factors, revealing that the capacity of Ghanaian SMEs to adapt supply chain management practices will be a critical determinant. Transformational leadership within these enterprises is essential for fostering innovation and navigating the new regulatory landscape 9. In conclusion, the application of the framework generates a nuanced set of findings. It confirms the AfCFTA’s significant potential but delineates a path fraught with structural, digital, and competitive challenges. The results indicate that the ultimate impact will be less a function of tariff liberalisation alone and more a product of integrated advancements in trade facilitation, digital governance, SME competitiveness, and macroeconomic stability.

Discussion
The evidence regarding the AfCFTA's impact on regional supply chains in Southern Africa, with specific relevance to Ghana, presents a nuanced picture. While the agreement holds significant potential, its direct effect on intra-African food trade is projected to be modest, as indicated by partial equilibrium modelling 5. Legally, the AfCFTA’s specific reference to foodstuffs within its exceptions for products in short supply adds little to the broader protections already afforded under Article XX(j) of the GATT 6. This underscores that the agreement alone is insufficient to drive transformation; complementary investments and policies are critical. For instance, persistent deficits in energy access highlight a fundamental infrastructural constraint that limits local value addition and supply chain development, irrespective of trade rules 20. 2,3
The realisation of benefits is further mediated by socioeconomic and political factors. The effective implementation of food security measures is often hindered by resource constraints and political economy challenges, delaying progress 19. Conversely, evidence suggests that bottom-up, private sector-driven growth in certain agricultural value chains can flourish spontaneously, indicating that supportive ecosystems for small and medium-sized enterprises (SMEs) are vital for leveraging the AfCFTA 22. This need for complementary mechanisms is reinforced by studies highlighting the importance of social capital networks for agricultural productivity 8 and the role of digital tools like blockchain in creating more inclusive regional value chains 23. 4
Analyses of trade patterns and policy confirm that the AfCFTA operates within a complex landscape. Research on Africa’s external trade arrangements illustrates the competitive context for regional integration 10, while studies on trade during the Covid-19 pandemic reveal the distinct vulnerabilities and responses of formal and informal sectors 17,12. The structure and growth of services trade, a key component of modern supply chains, also require specific attention within the AfCFTA framework 2. Furthermore, challenges such as cybersecurity threats for small-scale cross-border traders 7 and the complexities of taxing the digital economy 3 represent significant non-tariff barriers. Ultimately, the impact on supply chains will depend on overcoming these infrastructural, regulatory, and political hurdles to translate legal provisions into tangible gains, a point emphasised in broader analyses of African trade dynamics 13,15.
Conclusion
This methodological inquiry has established a robust, context-sensitive framework for analysing the African Continental Free Trade Area’s (AfCFTA) impact on Southern African regional supply chains from a distinct Ghanaian perspective. The integrated multi-method approach, combining network analysis, comparative institutional assessment, and qualitative engagement, is validated as essential for capturing the complex, non-linear dynamics of regional trade integration 12. Its application to the Ghana-Southern Africa corridor demonstrates its utility in moving beyond tariff-centric models to grapple with substantive realities, where infrastructural deficits, regulatory heterogeneity, and informal networks mediate formal agreement outcomes 6,24. The core methodological finding is that assessing the AfCFTA requires a dialectical understanding of structure and agency, accounting for both overarching rules and the granular practices constituting the real economy.
The primary contribution is the deliberate centring of an African, specifically Ghanaian, viewpoint within a regional supply chain analysis. By positioning Ghana as an extra-regional actor, the methodology challenges insular analyses and reflects the AfCFTA’s pan-African ambition. It incorporates evidence that Ghanaian businesses and diaspora networks are already embedded in Southern African economies, a factor critical for understanding actual trade pathways 7,8. Consequently, the research significance is twofold. First, it provides a template for African economies to assess their strategic positioning within the continental trade landscape beyond traditional blocs. Second, it underscores that supply chain resilience depends as much on intangible factors like trust, leadership, and cybersecurity as on physical infrastructure 9,19.
Practical implications for policymakers and business strategists are clear. For Ghanaian ministries, the framework advocates a diagnostic approach to identify viable sectoral linkages with Southern Africa, using principles from analogous trade corridor studies 1. Policy must also address critical constraints the methodology highlights, particularly digital trade governance and taxation ambiguities which could undermine gains in key growth sectors 2,3. For Ghanaian SMEs, leveraging the AfCFTA necessitates investment in supply chain capabilities and digital security, alongside an understanding of Southern Africa’s distinct regulatory and informal environments 14.
Future research avenues are plentiful. A critical next step is the longitudinal application of this framework to trace the evolution of specific value chains from implementation through to 2025. The interaction between mega-infrastructure projects and trade policy in reshaping logistical corridors also warrants dedicated study. Furthermore, the methodological tension between the AfCFTA and extra-continental trade arrangements, such as Economic Partnership Agreements, presents a complex field for refinement 10,20. How Ghanaian firms navigate these overlapping regimes is a crucial question for empirical investigation. Finally, the focus on informality invites deeper ethnographic research into how diaspora communities adapt to the new continental trade architecture.
In conclusion, comprehending the AfCFTA’s impact demands a methodology of commensurate sophistication to the agreement’s ambitions. The proposed framework, by synthesising quantitative mapping with qualitative depth and insisting on a defined national perspective, offers a pathway to such understanding. It acknowledges that transformation will be a contested process shaped by historical ties, contemporary constraints highlighted in regional outlooks 5, and the agency of enterprises. As the AfCFTA’s operational phase progresses, success will be measured in the reconfiguration of firm-level linkages and the strengthening of intra-African economic agency. This methodology provides the necessary tools to observe, analyse, and inform that pivotal transformation.
