A transformative initiative aimed at bolstering Cambodia’s logistics network by enhancing the resilience of its rural roads amidst the challenges posed by climate change. This forward-thinking project, driven by international organizations, provides a strategic framework designed to help Cambodia prioritize investments and interventions for rural road accessibility, which is crucial for poverty reduction, human development, and logistical efficiency.
Rural roads are the backbone of Cambodia’s transportation network. Spanning over 47,000 km and comprising about 75 percent of the total road infrastructure, these routes are essential for the 79 percent of the population living in rural areas, providing access to vital services and economic opportunities. Despite ongoing improvements, around 90 percent of these roads remain unpaved and vulnerable to climate impacts, especially floods.
To address these challenges and enhance the logistics network, the report proposes a two-step prioritization framework based on geospatial models: the Flood Disruption Model and the Logistic Supply Chain Model. The Flood Disruption Model simulates the impact of severe flood scenarios on rural roads, pinpointing routes whose disruption would significantly affect rural communities. The Logistic Supply Chain Model evaluates how road closures disrupt supply chain flows, impacting product prices and availability. By integrating indicators across inclusiveness, human development, and logistics, this framework assesses road criticality based on factors like poverty reduction, access to essential services, employment, and agricultural product flow.
This prioritization approach enables the Ministry of Rural Development to effectively allocate resources to the most critical and vulnerable road segments, ensuring investments yield the maximum benefits for rural communities and the logistics network. The report provides detailed geospatial analysis results, highlighting significant variations in accessibility and vulnerability across Cambodia’s provinces. For example, densely populated provinces like Battambang and Prey Veng face severe accessibility challenges during floods. Simulations of potential interventions, such as improved drainage and road surface upgrades, demonstrate substantial benefits in maintaining access to key services and ensuring the smooth flow of goods during floods.
Furthermore, the report offers practical applications of the framework at the local level, identifying the most vulnerable communes where road improvements should be prioritized. This detailed approach helps stakeholders target investments effectively, ensuring that the most critical rural roads receive the necessary interventions to enhance resilience and improve the logistics network.
While acknowledging limitations such as data quality and methodological simplifications, the report presents a robust framework for risk-informed investment prioritization. By combining advanced geospatial analysis with practical recommendations, it serves as a valuable resource for policymakers and development professionals involved in rural road infrastructure planning. By prioritizing investments based on climate vulnerability and geospatial analysis, Cambodia can strengthen its rural road network, support sustainable development, and enhance the efficiency of its logistics network, ultimately improving the livelihoods of its rural population.
