IoT, Smart Sensors and Cold‑Chain MonitoringWhy Caribbean Supply Chains Continue to Lose Value
Across the Caribbean, cold chain failures remain a persistent and costly challenge, even as Internet of Things (IoT) devices, smart sensors, and real time monitoring technologies become more widely available. Temperature sensors, global positioning system (GPS) tracking, and automated alerts are increasingly deployed, particularly within export-oriented supply chains handling fresh produce, seafood, meat, and pharmaceuticals.
Yet food loss and quality degradation during transport and storage continue to undermine trade competitiveness, food security, and export reliability across the region.
This apparent contradiction reflects a broader pattern observed in transport and logistics systems globally: technology adoption alone does not guarantee operational improvement.
The Food and Agriculture Organization of the United Nations (FAO) has highlighted that food loss in cold chains is most likely to occur during handling, storage, and transport transitions, i.e. points at which responsibility shifts between actors and accountability becomes diffused (FAO, 2023). Importantly, FAO’s analysis emphasises that losses are not caused solely by technical gaps, but by failures in governance, coordination, and decision-making frameworks. Sensors may detect temperature excursions, but institutions often lack the authority, protocols, or incentives required to act on that information in a timely and effective manner.
This finding aligns closely with the Inter-American Development Bank’s (IDB) assessment of digital transformation in transport systems across Latin America and the Caribbean. The IDB notes that while digital tools are increasingly introduced through pilot projects and standalone investments, many transport and port authorities lack integrated strategies that align technology deployment with governance arrangements, regulatory oversight, and cross agency coordination (Inter American Development Bank [IDB], 2022). As a result, digital solutions frequently operate in isolation, limiting their impact on operational performance and risk management.

In this short video, Ariel Miller, Communications & Creative Design Specialist explore why cold‑chain losses persist across the Caribbean despite growing use of IoT devices and smart sensors. Drawing on regional realities, Ariel explains how data alone does not prevent spoilage unless institutions have the governance frameworks, coordination mechanisms, and decision‑making authority to act on it.
IoT & Smart Sensors in Cold Chain Logistics
From Monitoring to Management: The Institutional Gap
Cold chain monitoring systems generate value only when data flows seamlessly across the supply chain and triggers timely, accountable action. In the Caribbean, this remains particularly challenging. Cargo often moves through multiple ports, terminals, carriers, and regulatory agencies within compressed timeframes, frequently across small and fragmented markets. Each handover introduces risk, especially where roles and escalation authority are not clearly defined.
FAO’s work on sustainable food cold chains underscores that temperature abuse commonly occurs at transition points—during loading and unloading, temporary storage, customs inspection, or power interruptions—rather than during steady state transport (FAO, 2023). In practice, this means that temperature alerts may be generated but not escalated, or that data may be retained within private platforms without clear protocols for sharing with customs, veterinary, or sanitary authorities.
The IDB has identified weak coordination between public and private stakeholders as a structural barrier to effective digital transformation in transport systems across the region (IDB, 2022). Without agreed governance arrangements, IoT deployments risk becoming passive monitoring tools rather than active instruments for loss prevention, regulatory compliance, and dispute resolution.
Research and policy guidance from the International Association of Ports and Harbors (IAPH) further reinforce this point. IAPH’s work on port digitalisation highlights that data driven systems deliver value only when port authorities have clear mandates over data governance, escalation procedures, and integration with port community systems (PCS) and terminal operating systems (TOS) (International Association of Ports and Harbors [IAPH], 2023). Where these institutional foundations are absent, digital tools tend to increase data volume without improving outcomes.
A Diagnostic Lens for Cold Chain Readiness
Rather than asking whether sensors are installed, Caribbean institutions should assess whether their cold chain systems are institutionally ready to use data as a management tool. The following diagnostic questions are intended to surface that readiness:
- When temperature deviations occur, is there a clearly defined escalation process with assigned responsibility across carriers, terminals, and regulators?
- Are cold chain data streams accessible to customs and sanitary authorities in real time, or only retrospectively?
- Is sensor data integrated into port community systems or terminal operating systems, or does it remain siloed within private vendor platforms?
- Have temperature thresholds and response protocols been standardised across the supply chain?
- Was cold chain monitoring implemented as part of a broader digital transformation strategy, or as a standalone technical solution?
FAO’s analysis of food supply chains emphasises that reducing losses requires coordinated, system wide action rather than isolated technological fixes (FAO, 2023). Where institutions struggle to answer these questions consistently, operational risk, regulatory exposure, and economic loss are likely to persist.
From Technology Adoption to Institutional Effectiveness
Strengthening cold chain performance in the Caribbean requires moving beyond procurement decisions toward structured readiness assessments, governance design, and cross agency coordination. This perspective is reinforced by regional development institutions, including the Caribbean Development Bank (CDB), which has identified cold chain infrastructure, logistics coordination, and institutional capacity as critical enablers of food security and export resilience in small island economies (Caribbean Development Bank [CDB], 2022).
Similarly, the United Nations Conference on Trade and Development (UNCTAD) has highlighted that small and vulnerable economies face heightened logistics risk due to fragmented markets, limited redundancy, and dependence on efficient port and transport systems (UNCTAD, 2023). In such contexts, digital transformation delivers results only when technology is aligned with operational processes, accountability frameworks, and regulatory oversight.
Altus Regional supports maritime authorities, port operators, logistics providers, and regulators in addressing these challenges through independent advisory services, including cold chain readiness assessments, data governance frameworks, and strategic road mapping for digital transformation initiatives.
