Cambodia: Geospatial Analysis for Resilient Road Accessibility for Human Development and Logistic Supply

Investment Rating - The report does not explicitly provide an investment rating for the industry. Core Insights - The report introduces a practical framework to assist the Ministry of Rural Development (MRD) of Cambodia in prioritizing investments and interventions for rural roads to achieve climate-resilient rural accessibility for poverty reduction, human development, and logistic supply [12][13]. - The proposed framework utilizes two core geospatial models: the Flood Disruption Model and the Logistic Supply Chain Model, to identify critical and climate-vulnerable road sections for prioritized interventions [13]. - The report emphasizes the importance of rural roads, which account for about 75% of Cambodia's total road network, in providing access to services and economic opportunities for the rural population [19][20]. Summary by Sections Introduction - The report aims to assist MRD in prioritizing rural road investments for climate resilience [12]. - The audience includes officials and decision-makers at MRD and other rural road authorities facing similar challenges [14]. Cambodia's Rural Road in the Face of Climate Change - Cambodia's rural road network spans over 47,000 km, with 90% remaining unpaved and undrained, posing challenges during the rainy season [20]. - Climate change increases vulnerability, with projections indicating a temperature rise of 0.7℃–2.7℃ by 2060 and more frequent extreme precipitation [24]. A Prioritization Framework for Resilient Rural Road Planning - The framework prioritizes communes based on a multicriteria analysis and selects roads through context-specific assessments [29]. - It integrates three development lenses: Inclusiveness, Human Development, and Logistic Supply, with six indicators to quantify the criticality of rural roads [30][31]. Underpinning Geospatial Models - The report details two geospatial models: the Resilient Accessibility Model and the Logistic Supply Model, which assess the criticality and vulnerability of rural roads [40]. - The Resilient Accessibility Model evaluates accessibility to key facilities, while the Logistic Supply Model simulates supply chain disruptions due to road closures [60]. Revealing the Climate Vulnerability of Rural Roads - The analysis reveals that about 70% of the rural population has access to referral hospitals within 60 minutes, and two-thirds can reach high schools within 30 minutes [71]. - The report highlights the significant impact of flooding on accessibility, with a focus on the socio-economic implications of road disruptions [70].
