| Abstract | Coffee intensification in Southeast Asia generates export revenues at mounting ecologicalcosts. This study conducts a systematic review and comparative quantitative synthesis oftwo contrasting production systems: Vietnam’s intensive Coffea canephora monoculture andThailand’s shade-grown Coffea arabica agroforestry, to quantify ecological trade-offs andinform sustainable policy. Following PRISMA guidelines, empirical evidence from 2000–2025was integrated on soil carbon dynamics, hydrological assessments, and Life Cycle Assessments(LCA). Key indicators included soil pH, Water Use Efficiency (WUE), Soil Organic Carbon(SOC) stocks, and biodiversity metrics. Vietnam’s high-input monoculture sustains leadingexport volumes but incurs severe environmental costs: nitrogen over-application has acceleratedsoil acidification (pH frequently below 4.0), triggered pathogen outbreaks (Meloidogyne spp.,Fusarium spp.), and caused over-irrigation reducible by 300–590 m³/ha (30–40%) withoutyield loss. Thailand’s agroforestry systems demonstrate clear ecological advantages: SOCstocks increased 12.1% relative to natural forests, microbial biomass remained stable, and LCAestimates show a 42% reduction in biodiversity damage potential compared with monocultures.A Hybrid Resilience Model is proposed that combines Vietnam’s precision irrigation withThailand’s agroforestry principles, offering a viable pathway to economically competitive,environmentally sustainable coffee production across Southeast Asia. |
