Pressures on fragile post-disaster supply chains mean practice-based knowledge should be harnessed

Regan Potangaroa (Auckland University of Technology - AUT), Kelvin Zuo (Massey University), Suzanne Wilkinson (AUT) explain why experience-led knowledge from the field, when triangulated with contemporaneous documentation, can constitute evidence for understanding post-disaster reconstruction systems. People working within reconstruction environments (engineers, builders, logisticians and community actors) provide crucial observations about how reconstruction systems function in practice, particularly supply chains, material flows, procurement and governance in post-disaster rebuilding. Integrating this knowledge can lead to better outcomes.

Experience is not anecdote

“When practitioner observations are anchored in the documentary record of reconstruction, experience ceases to be anecdote and becomes evidence.”

Disaster reconstruction is often described as one of the most complex challenges faced in the built environment. Reconstruction brings together disrupted markets, damaged infrastructure, urgent humanitarian needs, and multiple layers of governance operating under intense time pressure. Within this complexity, scholarly attention frequently focuses on institutional coordination, financial flows, and reconstruction policy frameworks. Yet reconstruction begins somewhere far more prosaic: in a yard where timber has not arrived, on a construction site waiting for delayed cement deliveries, and in those communities attempting to rebuild with whatever materials can be sourced locally.

Reconstruction, therefore, is not only a governance challenge but also a material one. Timber, cement, steel, and roofing sheets must move through fragile supply chains before houses, schools, and infrastructure can reappear. Procurement systems, the mechanisms through which these materials are sourced and delivered, therefore sit at the core of the rebuilding process.

Practitioner observations are often treated as anecdotal unless translated into more conventional forms of academic evidence. Yet when such observations are anchored in contemporaneous documentation (e.g. procurement records, operational reports, logistics data, and policy guidelines), they can form robust evidence to inform reconstruction practices.

The missing material dimension

Reconstruction policy discussions often concentrate on governance arrangements, financing mechanisms, and institutional coordination. These elements are undoubtedly important. However, they frequently fail to consider the availability of materials, without which reconstruction cannot begin. Procurement systems represent the material backbone of recovery (Le Masurier et al. 2008), yet procurement systems remain one of the least examined dimensions of disaster reconstruction research.

Across several major disasters over the past two decades, including the reconstruction following the 2004 Indian Ocean tsunami in Banda Aceh and Sri Lanka, the 2010 earthquake in Haiti, and the Canterbury earthquakes in New Zealand, similar procurement challenges repeatedly emerged (Chang et al. 2010).

Procurement systems designed to ensure transparency and accountability frequently struggled to deliver materials at the speed reconstruction required. Formal procurement mechanisms, designed to ensure compliance and certification, excluded local markets that might have supplied materials rapidly. Imported materials often arrived late or in forms mismatched to local construction practices, and contributed to supply bottlenecks, procurement concentration, and price volatility.

These dynamics and the opportunity costs of procurement rules rarely appear in official evaluations, although they govern the everyday experience of engineers managing construction sites, logisticians coordinating supply chains, and builders sourcing materials. Their experiences of how reconstruction systems function once policy frameworks meet the realities of disrupted markets could provide valuable insights to improve reconstruction outcomes and processes.

Experience as a source of evidence

Experience-led knowledge is sometimes dismissed as anecdotal where it originates from informal observation rather than controlled research design. However, disaster contexts challenge conventional assumptions about how knowledge can be produced. Reconstruction environments evolve rapidly: data collection is often incomplete, fragmented, or delayed and operational decisions often occur outside more common, formal structures. The key methodological question is therefore: How can knowledge originating from practice, and outside of formal research processes, be validated?

One approach commonly used in reconstruction research is triangulation of observations with contemporaneous documentation. Procurement guidelines, donor reports, logistics records, and policy documentation can create a documentary trail that situates practitioner observations within a broader evidentiary framework, helping validate experience-led observations.

For example, following the 2004 tsunami in Banda Aceh, local observations revealed that timber certification requirements were excluding local sawmills from participating in reconstruction supply chains. By triangulating these observations with procurement guidelines (which confirmed chain-of-custody certification was required) and with humanitarian logistics reports (which documented timber shortages during the early phases of reconstruction) the experience-led local observations were validated (Potangaroa, 2010).  This revealed an inadvertent systemic problem in the procurement system that would have gone unchallenged, undermining local reconstruction capacity and the success of reconstruction projects. Meanwhile informal supply networks frequently restored material flows faster than the formal procurement systems designed to regulate them.

Patterns across disasters

Across reconstruction efforts following the Indian Ocean tsunami, the Haiti earthquake, and the Canterbury earthquakes, similar procurement problems repeatedly emerged. These dynamics appear in both fragile and more robust construction economies. The recurrence of these patterns suggests that procurement fragility is not simply a function of institutional weakness. Instead, it reflects structural tensions within reconstruction governance itself.

The compliance paradox

A central insight emerging from these experiences might be described as a compliance paradox. Procurement systems are designed to ensure accountability because governments and donors must demonstrate that reconstruction funds are spent transparently and responsibly. Certification requirements, competitive tendering procedures, and supplier qualification standards are therefore introduced to prevent corruption and misuse of funds. Yet these same mechanisms can reduce the adaptability of procurement systems. For instance, certification requirements may exclude local suppliers who lack formal documentation. Centralised procurement systems can slow decision-making.

These issues are exacerbated in volatile post-disaster environments characterised by disrupted markets and urgent rebuilding needs (Murdoch & Hughes, 2008). In such circumstances, the pursuit of procedural certainty may undermine reconstruction efficiency. Practitioners in these environments frequently encounter these tensions directly.  Local traders can often restore supply networks more rapidly than formal procurement structures and can be critical to early recovery.   However, the local, informal markets are excluded because they do not have the same safeguards and are situated outside the official procurement reporting mechanism.  Experience-led observation therefore plays a role in both revealing this gap between policy design and reconstruction practice and identifying solutions.

Bridging research and practice

The reluctance to treat practitioner knowledge as evidence is indicative of broader divides between academic research and professional practice. Researchers undertake formal data collection and analysis to provide considered insights. Practitioners operate in environments characterised by uncertainty, incomplete information and time pressure. Experience-grounded analysis occupies a productive space between these perspectives. It draws on long-term field engagement while situating observations within documentary evidence and comparative reflection. In disaster research, where conventional data collection is often difficult, such approaches capture dynamics that might otherwise remain invisible. Thus, rather than replacing conventional research methods, experience-based analysis provides complementary insights more rapidly while still ensuring validity of the findings.

Towards a broader evidentiary framework

Engineers, logisticians, contractors, and community organisations possess valuable insights into the functioning of reconstruction systems. Methodological frameworks for experience-led knowledge in reconstruction research therefore require expansion and formal exploration and definition. This would allow field observations, practitioner reflections, and operational records to be integrated into a more comprehensive evidence base and be embedded in reconstruction policies, leading to better outcomes. Additionally, experience-based analysis helps reveal unintended consequences of reconstruction policies. It can also directly inform more effective reconstruction policies and procurement systems designed for disrupted markets.

Conclusions

Post-disaster reconstruction ultimately depends on the ability of procurement systems to deliver appropriate materials quickly and reliably. Yet the functioning of these systems is often poorly understood because much of the relevant knowledge resides in the experience of practitioners operating within disrupted environments.

When systematically analysed and supported by contemporaneous documentation, experience-led observations represent a legitimate methodological contribution and help ensure this knowledge doesn’t remain hidden. This approach can reveal patterns and operational realities which can contribute to achieving better reconstruction outcomes.
