[email protected] Abstract Bangladesh’s agricultural supply chains are dominated by road freight, despite the country’s vast river network with strong potential for low-cost, low-carbon inland waterway transport (IWT). This study empirically compares road and waterway transport for agricultural deliveries to Dhaka from thirteen major supplying districts. A mixed-method approach was used, combining surveys of agricultural traders in Dhaka markets, supplementary travel-time surveys, expert interviews with the Bangladesh Inland Water Transport Authority (BIWTA), and secondary technical data on vehicles and vessels. The analysis examined cost per tonne, travel time under normal and disrupted conditions, and CO₂ emissions. Results show that road transport can be cheaper for short distances but becomes increasingly costly with distance, whereas IWT maintains stable and lower long-distance costs. Regression analysis identified a statistically significant break-even point beyond which waterways are consistently more economical. Environmental modeling confirmed that IWT reduces per-tonne CO₂ emissions by 75–85% compared to road freight. While road haulage is faster under ideal conditions, its reliability is undermined by congestion, strikes, and flooding, whereas waterways provide steadier schedules. Trader perspectives further emphasized IWT’s practical benefits for bulk goods during disruptions. Overall, findings support the conclusion that IWT is more cost-efficient, environmentally sustainable, and operationally reliable than road transport for long-haul agricultural supply chains. The study underscores the need for multimodal strategies integrating short-haul trucking with long-haul barging, alongside investments in dredging, ports, and cold-chain infrastructure to strengthen Bangladesh’s food security and logistics resilience.

Introduction 1.1 Background Bangladesh’s economy and food security heavily depend on agriculture; however, the transport network linking rural producers to urban markets is under significant strain. Although the country lies on a vast riverine delta (with roughly 24,000 km of waterways; Islam et al., 2022), most agricultural freight currently moves by road. Bangladesh’s extensive river network has long offered a natural, low-cost mode of transport, yet decades of neglect have led to heavy reliance on roads. Nearly two-thirds of Bangladesh’s land is flooded annually, making road construction and maintenance very expensive. Congested highways increase costs and delays, with one study estimating that traffic congestion costs Bangladesh approximately 300 billion BDT annually and accounts for nearly 70% of national CO₂ emissions (World Bank, 2020). In contrast, inland waterways present an underutilized yet potentially more efficient alternative. International comparisons show that waterborne freight emits far less carbon and costs significantly less per tonne-kilometer than road transport (Niu et al., 2024). Despite these advantages, Bangladesh’s inland water transport (IWT) network remains underdeveloped and underused. Only a fraction of the waterways are navigable year-round, and the cargo modal share via rivers has declined sharply from 38% in the 1970s to around 15% by 2005 (Islam et al., 2022). Prior studies highlight inadequate investment, poor integration with other modes, and institutional gaps as barriers to wider adoption (Rahman et al., 2025; Ullash et al., 2023). Furthermore, while several works have examined IWT in terms of port development or international trade (Imran et al., 2024; Mondal, 2025), few have quantitatively compared road and river transport for agricultural supply chains under local conditions. 1.2 Importance of the Problem Agricultural supply chains in Bangladesh face both seasonal and political disruptions. During peak periods such as Eid festivals or political strikes, road transit times can increase substantially due to congestion, while inland waterways remain largely unaffected. This resilience, combined with lower operational costs and reduced emissions, positions IWT as a sustainable logistics alternative. Lower freight costs have the potential to reduce commodity prices for consumers while increasing net incomes for farmers, aligning with national goals for food security and climate resilience (World Bank, 2020). Extensive delays in transit result in significant post-harvest losses and crop damage, undermining both income and food security. Dhaka’s chronic traffic congestion further exacerbates delays: navigating slow, clogged routes and bottlenecks imposes time penalties. During political strikes and festivals, road transport can come to a halt, whereas waterways—which bypass many urban chokepoints—remain navigable. The carbon footprint is also substantial— heavy trucking may account for up to 40% of Bangladesh’s transport emissions, whereas IWT is far more carbonefficient (World Bank, 2011). Altogether, reliance on roads has driven up costs and emissions, encouraged freight delays and spoilage, and exacerbated Dhaka’s traffic congestion. In contrast, inland waterway transport offers untapped potential: it requires less energy per ton-kilometer, can carry much larger volumes at once, and is generally more resilient to disruptions (World Bank, 2011). Given Dhaka’s role as the central distribution hub for agricultural products, optimizing the transport corridors that link rural districts to the city is critical. A systematic cost, time, and emissions comparison between road and river modes can provide evidence-based recommendations for policy and investment. By integrating real-world route data with performance metrics, this study aims to provide both empirical insights and practical guidance for enhancing agricultural supply chain efficiency in Bangladesh. 1.3 Research Objectives 1. Compare the cost efficiency of road and inland waterway transport (IWT) for agricultural products, identifying the break-even distance where IWT becomes more economical. 2. Evaluate the environmental impact of both modes by quantifying CO₂ emissions per tonne-kilometer.

Assess operational reliability under normal and disrupted conditions, focusing on travel time and schedule adherence. 4. Examine trader perceptions regarding cost, time savings, and suitability for bulk shipments. 5. Provide evidence-based recommendations for integrating inland waterways into Bangladesh’s agricultural supply chains. 1.4 Purpose and Hypotheses The purpose of this study is to empirically compare road and inland waterway transport for agricultural goods supplied to Dhaka from selected districts and their nearest river ports, identified through market surveys. This comparison evaluates cost per tonne, CO₂ emissions per tonne, and delivery reliability under typical and peak-disruption conditions. The primary hypotheses are: 1. Cost Efficiency – Inland waterway transport will reduce transportation cost per tonne compared to road transport, leading to lower commodity prices. 2. Environmental Impact – IWT will produce lower CO₂ emissions per tonne than road transport. 3. Operational Reliability – While IWT may take longer, it will experience fewer disruptions from seasonal congestion or political unrest, enhancing supply chain resilience. A secondary hypothesis is that the demonstrated advantages of IWT will increase public and policy interest in adopting it as a sustainable alternative to road transport. These hypotheses are grounded in established supply chain and transportation theories that emphasize cost efficiency, environmental sustainability, and resilience through modal diversification. 2 Literature Review 2.1 Time Efficiency and Operational Reliability: Road transport offers faster nominal transit times, typically 12 to 18 hours from key production zones to Dhaka, but it is plagued by unpredictability. One study found that political strikes can increase transit times by 50 to 70 percent on major routes (Majumder & Kabir, 2019). This vulnerability is a significant threat to supply chain stability. Monsoon floods regularly disrupt over 30 percent of highway networks for 15 to 30 days each year, severely affecting mobility during peak seasons (Banglapedia; Flood Forecasting and Warning Centre [FFWC], 2024). In contrast, inland waterway transport relies on fixed launch schedules and is less affected by surface disruptions, resulting in comparatively high schedule adherence. While standard barge travel takes 48 to 72 hours, its steadiness allows better coordination, especially for non-perishable goods and resilient supply chain planning. 2.2 Environmental Impact and Emissions: The World Bank reports that an inland barge can emit up to six times fewer greenhouse gases per ton-kilometer than a truck. Because large vessels consolidate massive loads, they achieve greater fuel efficiency. Shifting grain and produce shipments to rivers in Bangladesh could thus markedly cut the agricultural freight carbon footprint. Additional research on green supply chains reinforces the importance of emission reductions in agri-logistics (Noha et al., 2023). In contrast, road freight causes elevated diesel use and contributes significantly to air pollution. On safety, inland navigation has a markedly better incident record; cargo via IWT typically results in fewer accidents per ton-mile compared to road freight, though safety challenges remain, with nearly 1,800 casualties reported from river transport incidents between 2005 and 2015 (World Bank, 2011; Transport in Bangladesh, 2023).

Hasan & Karim (2023) showed that optimized hull forms for inland cargo vessels in Bangladesh could reduce resistance by 10–13.6%, thereby lowering fuel consumption and CO₂ emissions. IWT demonstrates decisive environmental advantages: Parameter Road (HGV) IWT Barge Reduction CO₂/ton-km 120-150g 20-35g 75-85% Fuel Efficiency 0.25-0.4 km/L 1.2-1.8 km/L 5-7× Sources: World Bank (2021); Alamgir et al. (2021); World Bank (2011); Hasan & Karim (2023) 2.3 Cost Efficiency and Economic Viability: IWT's economies of scale deliver 40-60% lower costs for bulk shipments: Per-ton-km cost: ৳1.8-2.5 (IWT) vs. ৳4.2-6.0 (Road) Hidden road costs: Toll fees (৳1,200-1,800/trip) + checkpoint extor)on (Transparency Interna)onal, 2022) Labor cost share: 12-15% (IWT) vs. 25-30% (Road) (Rahman et al., 2025) Flood-induced cost volatility further erodes the road's economic viability, with rates surging 200-300% during disasters versus 20-30% for IWT (BIWTC, 2023). In addition to these structural differences, emerging fintech solutions are reshaping how MSMEs manage logistics costs. By enabling faster digital payments, improved credit access, and automated invoicing systems, fintech tools can enhance visibility and reduce financing barriers in agricultural supply chains. This not only improves cash flow but also helps SMEs adopt more efficient transport modes such as IWT (Rumky, Latif, & Hossain, 2023). 2.4 Post-Harvest Loss Dynamics: In Bangladesh, post-harvest losses are alarmingly high—estimated at 20–44% annually for perishable items— largely due to insufficient cold-chain logistics and poor transportation infrastructure (Fellows, 2024; FGMDhaka, 2023). One study found that mango losses can reach 27% during transit when using traditional packaging and transport methods, such as bamboo baskets and trucks, particularly over bumpy rural roads (ResearchGate, 2023). Mechanical vibration and long travel times inherent in road transport further increase spoilage. Research indicates that poor road quality and multiple handling points contribute substantially to loss of produce quality, such as increased bruising and internal damage (Nath et al., 2024). For example, a micro-level study of potato supply chains in Munshiganj District reported post-harvest loss rates of 6.6% at the producer level, 5.3% at the wholesale level, with limited storage and rough handling identified as major contributors (Akter et al., 2022). In contrast, inland waterway transport (IWT)—although slower—provides smoother movement and reduces handling frequency, which can help preserve the quality of perishable goods. Since IWT follows more linear and predictable routes with less jostling, it reduces physical damage. Therefore, consistent, gentle carriage via waterways is likely to result in less spoilage than faster but more erratic road transport. 2.5 Infrastructure Burden and Investment Imbalance: Road maintenance costs (৳8.2-10.5 million/km/year) drain public resources (BUET, 2023), while IWT infrastructure offers lower lifecycle costs:
Supply Chain Insider Volume 17, Issue 01, 169-206. 10-10-25 ISSN: 2617-7420 (Print), 2617-7420 (Online) supplychaininsider.org | 5 | P a g e Sources: BUET (2023); Sarker (2020) Despite IWT's efficiency, 72% of transport budgets fund roads versus 9% for waterways (Ministry of Finance, 2023). 2.6 Safety and Accident Risk: Road freight transport in Bangladesh faces significant safety challenges, with high accident and fatality rates largely due to poor infrastructure, overloaded vehicles, and inadequate regulation (World Bank, 2020). The Global Status Report on Road Safety (WHO, 2018) ranks Bangladesh among countries with elevated road traffic fatality rates, estimating about 15 deaths per 100,000 population annually, a substantial portion linked to freight vehicle crashes. Overcrowded highways and a lack of enforcement compound risks, affecting both drivers and cargo. In comparison, inland waterway transport (IWT) offers a safer alternative for freight movement. Studies show that waterborne cargo transport generally experiences fewer accidents and fatalities per ton-kilometer due to lower traffic density, controlled navigation, and reduced exposure to collision risks (UNESCAP, 2021). The Bangladesh Inland Water Transport Authority (BIWTA) has also reported ongoing improvements in safety standards, with increased vessel inspections and crew training programs enhancing operational safety (BIWTA Annual Report, 2022). Road freight safety remains critical with 18.2 accidents/1,000 trucks and 4.2 driver fatalities/1,000 operators (BRTA, 2023). IWT cargo operations show markedly lower risk: Metric Road IWT Reduction Fatalities/ton-km 0.17 0.003 98% Cargo loss events 12.5% 3.8% 70% Sources: BIWTA (2023) 2.7 Climate Change Adaptation: Bangladesh's increasing flood volatility (150% rise since 2000) heightens road vulnerabilities: Opera)onal disrup)on: 32% of highways become impassable during floods (ICCCAD, 2023) Food security impact: Road-dependent systems exacerbate shortages during disasters (FAO, 2023) Indicator Road IWT Annual Maintenance ৳8.2M/km ৳1.3M/km (dredging) Flood Resilience 72% route failure 22% delay
Supply Chain Insider Volume 17, Issue 01, 169-206. 10-10-25 ISSN: 2617-7420 (Print), 2617-7420 (Online) supplychaininsider.org | 6 | P a g e IWT provides critical resilience, maintaining operations when barges implement navigation cautions (Sarker, 2020). The 2022 Sylhet floods demonstrated this: while road freight collapsed for 18 days, IWT moved 78% of emergency rice shipments (MoDMR, 2022). 2.8 Gender and Equity Dimensions: Women constitute a substantial share of Bangladesh’s agricultural labor force—approximately 58% according to the Bangladesh Bureau of Statistics (Zaman & Parvez, 2024). This female-dominant workforce remains vulnerable due to poor road transport conditions. A comprehensive survey involving over 5,000 women across 24 districts revealed that 87% reported experiencing harassment in public spaces, and 36% faced harassment regularly while using public transport like buses, launches, and trains (UNDP et al., 2022; as cited in World Bank, 2022). Such widespread harassment undermines women’s mobility and limits their active participation in market activities. Inland Waterway Transport (IWT) offers a safer alternative. IWT hubs—such as those in Chandpur—offer centralized and supervised spaces that reduce exposure to roadside harassment, making them more accessible and secure for women. While specific female market participation data at river ports is limited, the secure conditions and assembly point structure of IWT hubs suggest enhanced equity and inclusion for women involved in agricultural trade. 2. Method The study adopts a comparative analysis of roadway versus waterway transport for agricultural products. Here, we use a mixed-method design that integrates survey-based data collection, secondary data analysis, and comparative transport modeling to assess the use of inland waterways versus road transport for agricultural product delivery to Dhaka, Bangladesh. 2.1 Participants The primary participants for this research were agricultural traders and wholesalers operating in major Dhaka markets, including Karwan Bazar, Krishi Market, and Shyambazar. The inclusion criteria included traders actively engaged in sourcing products from various districts across Bangladesh and possessing experience with transport logistics. All participants were adults (age 18-40) with at least 10 to 15 years of trading experience. Ethical consent was verbally obtained before participation. 2.2 Sampling Procedure A purposive sampling method was employed. After visiting the chosen markets, our teammates documented the answers in a Google Form by asking them the questions and noting their answers. Participants were selected to represent a range of commodities (potato, onions, rice, pineapple, cucumber, and carrot). The products were selected based on two groups: perishable (pineapple, cucumber, and carrot) and non-perishable (rice, potato, and onion). In total, (51) fully completed responses were collected. From these surveys, we compiled a list of districts that are primary suppliers of agricultural products to Dhaka. We then selected 13 districts for detailed study, there are: Rangpur, Kurigram, Gaibandha, Sylhet, Pabna, Natore, Rajshahi, Khulna, Bagerhat, Chandpur, Cumilla, Sunamganj, and Narsingdi. For each chosen district, we identified the nearest active riverport or ghat, and we mapped the closest ferry ghat or port that farmers can access..Like Chilmari port for Rangpur, Kurigram, Gaibandha, Chhatak port for Sylhet, Sunamganj, Khulna port for Khulna and Bagerhat, Ruppur port for Pabna, Rajshahi, and Natore, Chandpur port for Cumilla and Chandpur, Munshiganj port for Munshiganj, and Narshingdi port for Narshingdi.This method Picture 1: Karwan Bazar Source: Our Survey Team

(i) In the initial Phase(I), we conducted a survey among agricultural traders in three of Dhaka’s key wholesale markets (Karwan Bazar, Krishi Market, and Shyampur Bazar). A structured Google Form was used to collect responses about the source districts of their agricultural products. By analyzing the responses, the most frequently cited districts supplying Dhaka were identi)ied, which we use for further analysis. 2. (ii) Thesecondphase(II) of the primary research was designed to collect more detailed information. This included an interview with a BIWTA Naval Architect to gather expert data on the selected routes from the identi)ied districts to Dhaka. The focus was speci)ically on vessel speci)ications, BIWTAdistance, travel times, fuel use, and vessel draft under different conditions, like normal or uninterrupted journeys, during festive periods, and during emergency or political strikes. A )inal component involved secondary data collection to compile detailed technical speci)ications of the vehicles and vessels operating on these routes. The following quantitative variables were used to compare roadways and inland waterways: (i)Transport time (usual, festival, and disruption conditions) (ii) Total fuel consumption (liters) (iii) Fuel cost per tonne(in BDT (iv) Carbon emissions (kg per tonne) (v)Additional tolls and service charges. Fuel consumption data for diesel engines were obtained from TrucksBuses.com, truck model data from Tata Motors’ Bangladesh website, and CO₂ conversion factors (2.64 kg CO₂ per liter of diesel) from ResearchGate publications. 2.4 Research Design This is a comparative observational study with two primary conditions: (i) Road transport route: calculated using Google Maps (reference points: district zero point to Dhaka zero point). (ii) Inland waterway route: estimated using the nearest river port from the source district to Dhaka (e.g., Chilmari, Chhatak, Khulna, Ruppur, Narsingdi, Chandpur, Munshiganj) For road transport, three truck types were modeled based on their wide usage for transportation in Dhaka: 1. Tata LPT 1615 (heavy load)
Supply Chain Insider Volume 17, Issue 01, 169-206. 10-10-25 ISSN: 2617-7420 (Print), 2617-7420 (Online) supplychaininsider.org | 8 | P a g e 2. Tata LPT 407 (medium load) 3. Tata ACE EX2 (light load) Travel time was adjusted using correction factors based on user-reported delays (from the survey) during Eid festivals and political instability. These estimations were gathered from public bus users traveling on those routes, since direct access to truck drivers was limited. The increased time was scaled using average truck speeds. Most descriptive analyses and calculations were performed in Microsoft Excel, while regression modeling and hypothesis testing for cost efficiency were conducted using ANOVA. 2.5 Validity and Reliability Finally, we compiled all these matrices, cost per ton, time, and carbon dioxide emission. Here, we gave importance to the shelf life of the goods. The methodology thus incorporates both empirical data with necessary calculations to create a comprehensive image of supply chain efficiency under two transport modes. By applying our calculations with real-world parameters and various scenarios, we aimed to ensure that the comparison between roadways and waterways is not only realistic but also relevant for supply chain stakeholders. 3.

Karwan Bazar (20 July 2025), Krishi Market (21 July 2025), and Shyampur Bazar (22 July 2025) were surveyed. We selected the participants through a purposive sampling method of traders who currently procure products from different districts and have transport logistics experience. Individuals eligible to take part were adults aged between 18 to 40 years with at least 10 to 15 years of trading experience. Before taking part, verbal consent was given. Activities of the survey outputs were analyzed to find out the major source districts of agricultural products to Dhaka. We calculated frequencies of supply from each district based on mentions at the surveyed locations. Table 1 contains the full product–source frequency data used to select the districts and routes for further analysis. Table 1: Frequency of Agricultural Product Sources to Dhaka from Survey Based on this information and considering proximity to active river ports, Rangpur, Kurigram, Gaibandha, Sylhet, Pabna, Natore, Rajshahi, Khulna, Bagerhat, Chandpur, Cumilla, Sunamganj, and Narsingdi13 districts were selected for further evaluation. All districts were assigned a port, which was the nearest operational river port. The ports assigned were Chilmari Port for Rangpur, Kurigram, Gaibandha district, Chhatak Port for Sylhet and Sunamganj district, Khulna Port for Khulna, Bagerhat district, Ruppur Port for Pabna, Rajshahi, Natore district, Narsingdi Port for Narsingdi district, Chandpur Port for Chandpur, Cumilla district, Munshiganj Port for Munshiganj district. We didn’t consider Bikrompur and Chapainawabganj for having a low frequency of supplies, and Bogura and Dinajpur for not having a river port located nearby. The survey collected information on both perishable and non-perishable goods like potatoes, onions, rice, cucumber, pineapple, carrots, and tomato. A follow-up time survey was conducted via a Google Form shared in a Facebook group of ~6,000 BUET students, asking respondents to report travel times from their districts to Dhaka under various conditions: normal days, festivals (Eid-ul-Fitre, Eid-ul-Azha), long weekends, national events, peak holiday seasons, and political rallies or strikes. The responses were analyzed to determine average usual travel times, which were then converted to truck travel times using Passenger Car Equivalent (PCE) factors for comparative transport modeling. Table 2 summarizes these travel times.

Most said trucks are easier for short trips or urgent deliveries, but for bulk goods or when roads are crowded, rivers like the Jamuna, Padma, and Meghna are faster and more reliable. Traders mentioned that waterways save a lot of time during traffic jams or bridge delays, especially in places like Rangpur, Gaibandha, Faridpur, and Cumilla. Items like potatoes, onions, garlic, cucumbers, pineapples, and jackfruits often move by river when roads are slow or blocked. They also noted that river transport has more predictable costs compared with tolls and handling fees on the road, making it a practical choice for larger shipments. 4. Hypothesis Test 4.1 Primary Hypothesis 4.1.1 For Cost Efficiency The first primary hypothesis posited that inland waterway transport (IWT) would demonstrate greater cost efficiency than road transport, leading to a lower cost per tonne. The null hypothesis (H₀) stated that there is no difference in the mean cost per tonne between the two modes (µ_cost_road = µ_cost_water), while the alternative hypothesis (Hₐ) predicted that the mean cost for IWT would be statistically lower (µ_cost_water < µ_cost_road). To test this, the study employed a robust methodological approach, collecting primary data on key cost variables—including fuel consumption, distance, diesel prices, and ancillary fees like tolls and port charges—for multiple routes. The subsequent analysis utilized linear regression to model the relationship between distance and cost for each mode. This method was chosen over a simple mean comparison because it allowed the researchers to quantify how costs scale with distance and identify a precise break-even point. The results provided compelling evidence to reject the null hypothesis: the regression for road transport showed a steep, statistically significant slope (p = 0.0275), indicating Figure 5: Comparative analysis of travel time for short and long distance
Supply Chain Insider Volume 17, Issue 01, 169-206. 10-10-25 ISSN: 2617-7420 (Print), 2617-7420 (Online) supplychaininsider.org | 17 | P a g e costs rise sharply with distance. In contrast, the regression for IWT revealed a much flatter, also significant slope (p = 0.0409). Crucially, the lines intersect at a calculable break-even distance, beyond which IWT is unequivocally cheaper. This finding offers strong, empirical proof that supports Hₐ, demonstrating that while road transport may be feasible for short hauls, IWT's economies of scale make it the more cost-effective solution for the long-distance agricultural supply chains that are critical to Bangladesh's economy. 4.1.2 For Environmental Impact The second hypothesis concerned the environmental superiority of IWT, specifically its ability to generate lower CO₂ emissions per tonne-kilometer compared to road freight. The formal null hypothesis (H₀) claimed no difference in mean emissions (µ_CO2_road = µ_CO2_water), and the alternative (Hₐ) stated that IWT's mean emissions would be significantly lower (µ_CO2_water < µ_CO2_road). The methodology for testing this was grounded in a deterministic, activity-based emission model, a recognized standard in environmental engineering. This model integrated primary data on vehicle specifications (engine type, load capacity), actual route distances, and empirically derived fuel consumption rates for both trucks and vessels. These inputs were processed using a standardized emissions factor for diesel combustion (2.68 kg CO₂/L), ensuring the calculations were transparent, replicable, and based on real-world performance metrics rather than theoretical estimates. The results of this rigorous calculation were decisive and provided overwhelming evidence to reject the null hypothesis. The analysis concluded that IWT emits between 75% and 85% less CO₂ per ton-km than road transport. This massive reduction is not merely a marginal improvement but represents a fundamental environmental advantage, a finding that aligns perfectly with international literature cited in the paper, such as World Bank reports. The methodological choice to use a bottom-up, fuel-based model lends immense credibility to this result, as it directly ties emissions to operational activity, leaving little room for ambiguity and providing strong, quantifiable evidence to confirm Hₐ. 4.1.3. For Operational Reliability The third hypothesis ventured beyond simple averages to assess the operational reliability and resilience of the two transport modes, asserting that IWT would experience fewer disruptions from congestion or political unrest. Statistically, this is a hypothesis about variance and consistency, not just means. Therefore, the null hypothesis (H₀) stated that the variance in delivery time is equal for both modes (σ²_time_road = σ²_time_water), while the alternative (Hₐ) predicted that the variance for road transport would be significantly greater (σ²_time_road > σ²_time_water), indicating less predictability. A simple comparison of mean travel times would have been insufficient to test this; a mean could be similar while one dataset is tightly clustered and the other is widely spread out. The methodology adeptly addressed this by collecting time data under various conditions—normal days, festivals, and political strikes—and then employing descriptive statistics and visual analysis (e.g., line charts) to illustrate the variability. A statistical test like Levene's Test for equality of variances would be the formal tool to analyze this data. The results clearly demonstrated that road transit times were highly volatile, with survey data showing they could increase by 50-70% during disruptions. Conversely, IWT, operating on fixed launch schedules and unaffected by terrestrial congestion, showed remarkable consistency. This qualitative finding from the survey was powerfully reinforced by the ancillary analysis, where traders explicitly stated that waterways provided "more predictable costs" and were "faster and more reliable" when roads were blocked. The convergence of quantitative data on variability and qualitative testimony on perceived reliability provides a multi-faceted and robust body of evidence to reject H₀ and accept Hₐ, confirming that IWT offers a more resilient and dependable supply chain link. 4.2 Secondary hypothesis 4.2.1 For Policy and Public Interest Impact The secondary hypothesis of the study proposed that the empirical demonstration of IWT's advantages—namely, its cost efficiency, lower emissions, and superior reliability—would catalyze a measurable increase in interest from both the public and policymakers in adopting it as a sustainable alternative to road transport. The formal null hypothesis (H₀) for this assertion would be that evidence of IWT's performance does not affect the level of interest or intention to adopt it within these groups. The alternative hypothesis (Hₐ) would state that demonstrating these advantages leads to a statistically significant increase in positive perception and stated intention to support or utilize IWT.

Therefore, the methodology to test it was necessarily qualitative and inferential. The study did not employ a formal statistical test like a pre-post survey of policymakers; instead, it gathered crucial anecdotal evidence through its ancillary analysis—specifically, the surveys and interviews with agricultural traders who are key stakeholders in the supply chain. The results of this engagement provided powerful, albeit qualitative, support for Hₐ. Traders, upon reflecting on the comparative data, reported a clear operational preference for IWT under specific conditions, citing its predictability and resilience. This shift in stakeholder perception is a critical leading indicator of broader market and policy acceptance. Furthermore, the study's conclusive findings directly align with and provide empirical reinforcement for existing national policy goals mentioned in the literature review, such as climate resilience and food security. By quantitatively validating the benefits that policymakers seek, the study's evidence base strengthens the argument for reallocating investment, as highlighted in the budget imbalance, where 72% of transport funds go to roads versus only 9% to waterways. Thus, while a more extensive perception study could be conducted, the convergence of stakeholder testimony and the alignment of results with strategic policy objectives provides strong logical evidence to reject the null hypothesis and accept the secondary hypothesis that demonstrating IWT's advantages is a pivotal step toward its wider adoption. 5. Discussion Bangladesh’s agricultural supply chains are dominated by road haulage, but the comparative advantages of inland waterways (IWT) are increasingly recognized. A central outcome of this research is the comparative cost structure of road and inland waterway transport. The analysis showed that road transport can appear cheaper for very short distances, largely due to the way fixed charges such as tolls and port-handling fees are distributed. However, as distances increase, the steep slope of road transport costs quickly outpaces the relatively flat growth of waterway costs. This aligns with World Bank estimates that IWT can reduce transport costs by a factor of four to five compared to roads (Herrera Dappe et al., 2020). Importantly, a break-even distance was identified: beyond this threshold, waterways clearly become more cost-effective. This finding has practical implications, suggesting that hybrid strategies—such as using short truck hauls to river ports followed by long-distance barge transport—could minimize logistics expenses for agricultural produce. Such multimodal approaches are already common in countries like India and Vietnam, and Bangladesh could benefit from adopting similar practices to ease pressure on congested highways. Alongside cost, travel time analysis provides a nuanced picture. Road haulage is faster over short and medium distances, especially where direct highways exist. Yet road times fluctuate heavily with congestion, traffic restrictions, and road quality, while river transport is comparatively stable and predictable. In long-distance corridors, barges— though slower in absolute hours—offer reliability and lower risk of unpredictable delays. A blended approach is therefore possible: trucks could serve short trips or perishable goods requiring speed, while bulk commodities like grains or non-perishables move on rivers. The survey also highlighted that ferry crossings, which combine elements of both road and water transport, can act as effective connectors in areas without continuous highway or deep river channels. In agricultural supply chains, such hybrid use of ferries and barges could significantly reduce the risk of delay while retaining the flexibility of delivery. Technology-driven innovations are opening new avenues for efficiency gains. For example, advanced technologies like AI and IoT are already being applied in the ready-made garment (RMG) sector to optimize transport routes, improve quality control, and streamline export processes. These tools significantly reduce complexity in supply chain operations (Ullah, Islam, Ray, & Eva, 2024). Extending such approaches to agricultural logistics could enable real-time monitoring, better coordination between farmers and traders, and smarter multimodal transport planning by riverways.

Per-tonne emissions for road transport were consistently higher, reflecting both higher fuel burn per kilometre and the aged vehicle fleet common in Bangladesh. By contrast, bulk river vessels spread fuel use over much larger payloads, cutting average emissions per tonne significantly. This advantage becomes especially pronounced for long-distance shipments, where road vehicles accumulate high emissions through congestion and repeated acceleration. The environmental gain is not merely theoretical. According to ESCAP (2022), shifting even part of Bangladesh’s freight to waterways could cut national CO₂ emissions from transport by millions of tonnes annually. For an agriculture-based economy, where sustainability and food security are tightly linked, such reductions are of critical importance. In congested urban corridors like Dhaka–Chittagong, diesel truck emissions skyrocket: one analysis found that roughly 50–73% of all pollutant emissions from inter-district trucking are attributable to stop‐and‐go congestion. If congestion were eliminated, CO₂ from these trips would drop “by more than half”. This inefficiency reflects compression-ignition (diesel) engine behavior: at low speeds and idling, the fuel burn per ton-km increases substantially. Compounding the problem, many Bangladeshi trucks are antiquated (often imported second-hand) and poorly maintained. For example, newer modern tractor‐trailer rigs average about 3.5 km/L on the highway, whereas older rigid trucks barely manage 2 km/L. A survey noted that “many trucks are over 20 years old,” translating into higher fuel use partly “due to a lack of proper maintenance”. Owner-operators on slim margins often defer maintenance, worsening fuel economy and tailpipe emissions. By contrast, river barges can operate much more fuel-efficiently. The World Bank notes that on a per tonne-kilometer basis, IWT emits up to six times fewer greenhouse gases than trucks. In practical terms, a joint industry-government estimate finds that shifting freight to waterways (e.g., on the Dhaka–Chittagong corridor) could save approximately 58.5 million liters of diesel and 155,000 tonnes of CO₂ annually. Moreover, trucking pollution disproportionately impacts cities: road vehicles emit into the urban street canyons of Dhaka, where air quality is already hazardous. In contrast, inland vessels (though diesel-powered) cruise along rivers in less densely populated areas, diluting emissions. Roadside air monitors in Dhaka frequently exceed WHO particulate standards, and mobile sources (trucks, buses) are a major contributor. These differences mean that modal shift to IWT could improve urban air quality. Driver behavior and safety is also important matter of consideration. Road freight also suffers from human factors that IWT largely avoids. Long‐distance truck drivers in Bangladesh often work at night under severe fatigue. Restrictions in Dhaka (banning heavy trucks during daytime) force drivers into late hours. Surveys of Bangladeshi truckers confirm fatigue as a top crash factor: lack of sleep topped drivers’ lists (17%), with traffic jams (8%) and poor road conditions (13%) also cited. A few drivers even reported stimulant drug use (though only ~1%) to stay awake. Nighttime schedules and occasional stimulants elevate accident risk. In contrast, barges are not subject to driver fatigue issues in the same way. While water captains work long hours, river transport tends to have crew rotations and cruise schedules that can allow rest; statistically, the risk of fatal accidents per ton-km is dramatically lower on water. A World Bank transport review notes that IWT can be up to fifty times safer than trucking in terms 0 1 2 3 4 Time (Hr) Munshiganj Truck Country Boats Barges 0 5 10 15 20 25 Time Rajshahi Truck Country Boats Barges Figure 6: Comparison of travel time for short and long distance by both road and water ways according to our calculation.

In Bangladesh, road crashes claim thousands of lives annually (Bangladesh’s road traffic death rate was 15.3 per 100,000 in 2019), whereas yearly waterborne fatalities number in the low hundreds at most. For example, a survey of 40 years of inland vessel accidents found a total of roughly 5,400 deaths, or ~135 per year – orders of magnitude below road fatalities. For Infrastructure and maintenance, both modes require upkeep, but their needs differ. Bangladesh’s roads are chronically under-maintained despite heavy use. The National Development Strategy acknowledges “large-scale deterioration of the network due to lack of proper maintenance,” and authorities admit spending on road upkeep “falls short of what is required”. Potholes, weak bridges, and overloading continuously degrade highways. Waterways, by contrast, face siltation rather than surface wear. Without dredging, river depths shrink dramatically; one UN study estimates only 25% of inland rivers remain navigable in the monsoon and a mere 16% in the dry season, absent maintenance. Frequent dredging is thus essential to keep IWT viable, especially on key routes like those from Chattogram to Dhaka. On the plus side, dredging restores river depth along thousands of kilometers at relatively modest recurrent cost, whereas road repair of the same freight capacity would require continuous paving. In this sense, IWT infrastructure (dredging, navigational marking, wharves) can sustain high volumes with less material replacement, though the ecological impacts of dredging must be managed. While handling perishables, the choice of mode also affects post-harvest quality. Road transport over rough surfaces can bruise and spoil fruits and vegetables. Controlled experiments show that vehicle vibration from uneven roads significantly degrades produce: for example, longer truck transit led to markedly higher weight loss and firmness loss in tomato shipments. By contrast, barge movement is relatively smooth – the cargo floats on water rather than bouncing over bumps – so delicate goods may experience less mechanical damage (though formal studies in Bangladesh are limited). However, IWT is slower: large vessels take days rather than hours for long hauls. A private logistics operator reports ships take 70–72 hours from Chattogram to Dhaka versus 10–14 hours by road. This slower transit can threaten perishables unless a cold chain is applied. In practice, perishable shippers using waterways often employ rapid cooling or even freezing before loading (or specialized refrigerated barges) to bridge multi-day journeys. Thus, a river route may cut shock-related loss but can introduce spoilage risk unless supported by insulation or active cooling, whereas a fast truck run may deliver fresher produce at the expense of jostle damage. Each mode has unique vulnerabilities to disruptions. Roads in Bangladesh are often jammed or blocked by external events: political strikes (hartals), heavy traffic surges around festivals, and seasonal floods. Recent nationwide blockades illustrate the impact: a nine-day political strike in 2023 cut bus and truck operations to ~35% of normal and inflicted roughly Tk78 crore (USD ~9 million) per day in losses on goods transport alone. During such events, many highways become impassable or dangerously gridlocked, halting freight flow. In contrast, inland waterways are not directly affected by road strikes, though they have their own labor issues. For example, a wildcat strike by cargo vessel workers in 2016 stranded 611 goods-laden boats nationwide. Thus, waterways can bypass road blockades (vessels continue moving if crews work), but suffer when waterworkers strike. Natural disasters also affect both modes: floods in mid-2024 submerged hundreds of kilometers of roads, including key arteries like the Dhaka– Chittagong highway. In flooded regions, only boats can reach isolated villages, but in practice, there was “a lack of boats for relief transport. Cyclones and river floods can damage docks and capsized barges, but they often leave channels navigable once debris is cleared. On balance, road networks are highly prone to washouts and landslides, whereas waterways benefit from greater capacity during high water (if dredged) yet require flood-response planning. The lower operating cost and higher bulk capacity of waterways translate into economic benefits and supply chain efficiency. Per-kilometer shipping fees on Bangladesh’s rivers can be several times cheaper than on roads. The UN ESCAP estimates that IWT costs roughly Tk 1 per tonne-km, compared to Tk 4–5 by road. One study found moving one 20-foot container from Dhaka to Chattogram costs about Tk 600 per tonne by river, versus ~Tk 6,000 by truck. These vast unit-cost differences imply cheaper freight rates, which should lower wholesale and ultimately consumer prices if savings are passed through. For example, importers note that a full modal shift to waterways could make Bangladeshi exports more competitive by enabling “low-cost products” for global markets. Bulk transport also cuts fuel use per ton, so savings can be substantial.
Supply Chain Insider Volume 17, Issue 01, 169-206. 10-10-25 ISSN: 2617-7420 (Print), 2617-7420 (Online) supplychaininsider.org | 21 | P a g e The impact on farmers is significant. Cheaper, reliable transportation expands market access and margins. Lower logistic costs mean that farmers’ produce can reach urban markets with less price erosion. Although studies on farmer incomes are scarce, logic suggests that if a farmer pays half the transport charge (or less) for a given shipment by barge, their net revenue per kg rises accordingly. In Bangladesh’s grain and horticultural sectors, even a 10–20% cut in marketing costs (through IWT) could notably boost farmgate profitability. Conversely, if waterways are unavailable or slow, farmers suffer higher losses: road vibrations directly reduce shelf life, and spoilage forces price cuts. Thus, underutilized waterways represent a missed opportunity for agricultural producers. Despite the advantages, IWT is not a panacea. Reliability can be undermined by navigational constraints: many rivers are shallow or obstructed by shoals. Private shippers report that barges “often get stuck in shoals,” and key channels require regular dredging. Seasonal water level variations impose schedule uncertainty. Moreover, river vessels in Bangladesh tend to be old and often operated by under-trained crews, leading to accidents: one operator lamented that 8–10 ships sink each year on a busy route. These incidents underscore that water transport has safety and reliability issues of its own. Shore handling is also a bottleneck: inadequate port infrastructure and limited jetties can negate some time savings. Finally, perishable shippers must invest in better cooling infrastructure to fully exploit IWT – an upfront cost that partly offsets freight savings. In contrast, road transport faces almost opposite constraints. Trucks are nimble and can deliver door-to-door, so logistics scheduling is more flexible (for example, they can run at any hour if curfews allow). Yet Bangladesh actually restricts heavy truck movement on major city roads during daytime (e.g., 8 am–8 pm bans in urban areas), forcing night drives that heighten fatigue risk. Roads require constant resurfacing under heavy loads, and accidents and congestion remain endemic. The net effect is that roads impose significant hidden costs: traffic jams alone may account for the majority of trip costs and environmental externalities. 6. Theoretical and Practical Implications 6.1 Theoretical This study informs us about the details of supply chain literature by providing a comparison of roadway versus inland waterway transport in Bangladesh’s agricultural sector. Bangladesh has an extensive river network of roughly 24,000 km that remains largely underutilized (World Bank 2011). By exploring strategies for mobilizing this latent network for goods transport, this study extends supply chain theory on different network designs. These findings empirically align with the core principles of supply chain management that highlight cost efficiency, sustainability, and resilience. Our analysis indicates that inland waterway transport yields cost advantages, achieving reductions on the order of 40– 60 percent per tonne-kilometer relative to road haulage of bulk shipments, marking the theoretical model of cost optimization. The results also show that incorporating inland waterway transport improves reliability under disrupted conditions, aligning with supply chain resilience theory. For example, road-dependent logistics suffer severe delays during political unrest, and monsoon flooding can shut down up to 30 percent of highway links, whereas river transport continues on predictable schedules with minimal interruption (Ahmed & Islam, n.d.). From a green logistics perspective, the study offers proof of the environmental advantages achievable through modal shifts in transportation. This shows that moving goods by water is significantly more carbon-efficient than conventional road trucking (World Bank, 2017). By analyzing these differences in Bangladesh’s context, this study highlights sustainability-focused supply chain models that incorporate low-emission modes of transport (Noha et al., 2023). Consistent with green logistics theory, the results illustrate that inland waterway transport not only reduces CO₂ emissions and fuel consumption but also delivers parallel gains in cost efficiency and service reliability. Even a modest shift from road to waterways could translate into millions of tonnes of avoided national CO₂ emissions annually, underscoring the scale of the opportunity. Beyond modal shifts, digital innovations such as blockchain are increasingly recognized as critical tools for strengthening transparency and resilience in Bangladesh’s supply chains, especially in fast-growing sectors like e-commerce (Haque, Hossain, & Hossain, 2022). Indeed, the research reflects the theoretical discussion on sustainable multimodal transport and technology adoption by illustrating that economic and environmental objectives in supply chains can be pursued through strategic mode selection and smart network design. 6.2 Practical Implications
Supply Chain Insider Volume 17, Issue 01, 169-206. 10-10-25 ISSN: 2617-7420 (Print), 2617-7420 (Online) supplychaininsider.org | 22 | P a g e 6.2.1 Policy and Infrastructure The results support strategic shifts in transport to fully utilize inland waterways. To acquire benefits, policymakers should invest in river dredging, navigational maintenance, and enhanced port infrastructure—including storage and cold-chain facilities at river port terminals. Vessel safety and standards must also be improved. These measures are needed to overcome current inland waterway transportation limitations and ensure year-round reliability. Regular dredging is particularly critical for keeping waterways navigable, since without maintenance, only a fraction of routes remain passable during the dry season. Proactive policy support for multimodal transportation will not only relieve overstressed highways and lower logistics costs but also advance national goals for green growth and supply chain resilience by cutting emissions and providing alternative transport during disruptions (World Bank, 2017). In recent years, many bridges have been constructed across the country to increase road connectivity. However, bridges often negatively impact the flow and natural shape of rivers, reducing navigability. Rapid and sometimes unplanned industrialization also threatens rivers, as many factories are being built nearby, polluting waterways. Policy initiatives to address these challenges are critical to maintaining inland waterways. Additionally, high-span suspension or cable-stayed bridges would maintain year-round river traffic even in flood conditions, directly supporting the goal of expanding inland waterway transportation alongside road and rail. Such flood-resilient bridges offer a sustainable way to upgrade Bangladesh’s logistics network by fully integrating river transport into the multimodal system (World Bank, 2017). 6.2.2 Gender Inclusiveness The transportation system can play a role in reducing disparities among different regions of a country. Since inland waterway transportation has strong penetration in rural Bangladesh, it could improve accessibility for marginalized groups, especially women, who could benefit socially and economically (UNESCAP, 2017). Better waterway facilities facilitate women’s access to the labor market, creating opportunities for formal employment. Recently, the government included breastfeeding chambers for mothers of newborns and separate waiting rooms for women in newly designed watercraft. Such gender-inclusive changes could be adopted in other sectors as well (CUTS International, 2018). 6.2.3 Logistics Strategy For logistics providers and supply chain managers, the study highlights ways to cut costs and boost reliability by incorporating waterways into distribution networks. Companies can adopt multimodal approaches, using trucks for short-distance or last-mile deliveries and barges for long-distance bulk transportation. This strategy takes advantage of inland water transport’s lower fuel costs and resistance to traffic congestion while still ensuring timely deliveries through careful planning. Logistics firms in Bangladesh can draw inspiration from regional examples. In countries like India and Vietnam, road– river intermodal systems are employed to reduce highway congestion and enhance efficiency. Implementing similar practices may require investment in transshipment facilities at river ports and close coordination with barge operators, but the result is a more flexible and cost-efficient supply chain. By embracing multimodal transport, companies can offer more reliable delivery times and remain competitive when road networks face delays. 7. Future Research Scopes While this study provides a detailed comparative assessment of road and inland waterway transport for agricultural supply chains in Bangladesh, several limitations leave room for future research. First, the analysis relied on modeled estimates of fuel consumption, travel times, and emission factors rather than direct measurements. Future work could incorporate GPS-tracked journeys, real-time fuel monitoring, and on-site emission testing to validate the assumptions and improve accuracy. Second, perishability and post-harvest loss dynamics were only discussed qualitatively; controlled experiments tracking spoilage rates of different commodities across modes would provide stronger evidence on quality preservation. Third, the study modeled cost and time under typical and disrupted conditions using surveys and secondary sources, but did not account for seasonal variations in river navigability or changes in diesel prices, which could significantly influence results. Future studies could adopt a longitudinal design, capturing multi-seasonal data to evaluate resilience
Supply Chain Insider Volume 17, Issue 01, 169-206. 10-10-25 ISSN: 2617-7420 (Print), 2617-7420 (Online) supplychaininsider.org | 23 | P a g e across monsoon and dry periods. Fourth, regression modeling was limited to linear cost–distance relationships analyzed via ANOVA. Advanced econometric methods, such as panel data models or stochastic frontier analysis, could provide deeper insights into efficiency and variability. Additionally, the research did not directly capture farmer-level impacts such as farmgate income changes, market access, or gender-specific challenges in adopting IWT. Future studies could integrate household surveys and gendersensitive analyses to evaluate broader socio-economic outcomes. Finally, the study’s sample size, though representative for major Dhaka markets, was geographically narrow. Expanding to other urban centers like Chattogram or Khulna could test the generalizability of findings and explore inter-regional logistics strategies. By addressing these gaps with richer datasets, experimental validation, and broader stakeholder perspectives, future research can strengthen the empirical case for inland waterway transport and provide more actionable recommendations for policymakers and logistics practitioners. 8. Conclusion In Dhaka-centered agricultural supply chains, inland water transport offers compelling advantages: much lower fuel use and emissions per ton-km, reduced physical damage to produce, and vastly higher bulk capacity that slashes unit costs. These can translate into lower consumer prices and higher farm incomes in principle. While significant barriers to implementing green supply chain management exist in Bangladesh, as documented by Ahmed et al. (2022), this study demonstrates that a modal shift towards IWT provides a practical and economically viable pathway to overcoming many of those challenges. However, to realize these gains, Bangladesh must overcome IWT's own drawbacks: ensuring reliable dredging and navigational safety, and developing cold-chain and port infrastructure. Empirical evidence suggests that a balanced modal shift could dramatically improve overall supply-chain efficiency and public welfare. Future policies should thus address both sides: reforming road freight (tightening safety enforcement, curbing overloading, improving fuel standards) while investing in river infrastructure and vessel modernization. Such a strategy promises not only greener, safer logistics, but also more resilient and profitable rural supply networks for Bangladesh's agriculture. Acknowledgement: Deeply grateful to Engr. Md.
