Abstract

Riau Province, a low-lying region dominated by peatlands and high rainfall, is highly susceptible to severe flooding, posing significant risks to its key agricultural sectors (oil palm and rice). This study seeks to delineate flood risk and agricultural susceptibility by amalgamating Geographic Information Systems (GIS) with Multi-Criteria Analysis (MCA). Flood hazard zonation was generated using weighted physical parameters—Digital Elevation Model (DEM), rainfall, soil type, land cover, and river proximity—processed through the Analytical Hierarchy Process (AHP). Agricultural vulnerability was assessed using exposure, sensitivity, and adaptive capacity indicators derived from 2020–2025 secondary data. The results reveal that 18.5% of Riau Province falls under high-hazard zones, predominantly in Indragiri Hilir and Indragiri Hulu. Rice and oil palm in Indragiri Hilir were found to be the most vulnerable commodities, with an estimated annual economic loss of 350 billion Rupiah [11]. The resulting spatial maps provide essential guidance for the Riau Provincial Government in designing targeted mitigation measures, risk-based spatial planning, and improved agricultural adaptation strategies.

Abstract

This study empirically analyzed the impact of Digital Transformation (DT) on Agricultural Marketing Value Chain Efficiency (VCE) across 12 developing economies from 2019 to 2023, utilizing a Fixed Effects (FE) panel data model. The research specifically quantified the contribution of Digital Access (ACCESS), ICT Infrastructure (INFRA), and Digital Policy (POLICY) on Marketing Margin (MM), Post-Harvest Loss (PHL), and Farmers’ Terms of Trade (FTT). The FE results indicate that ACCESS and INFRA robustly and significantly reduce MM and PHL while positively impacting FTT. Notably, INFRA showed the largest effect: a 1 unit increase in INFRA (mobile-broadband subscriptions per 100 inhabitants) correlates with a 0.398 percentage point drop in MM, confirming that network quality is paramount for supply chain streamlining and reducing information asymmetry. Conversely, the POLICY variable was largely insignificant. Supplementary analysis attributes this weakness to policy frameworks overemphasizing upstream (production) technology and neglecting critical downstream (marketing and logistics) inefficiencies. The study concludes that while market-driven DT investment is a proven driver of VCE, the full potential of government intervention requires a strategic reorientation toward addressing downstream value chain challenges.
