Tóm tắt	Environmental commodity chain analysis applies the global commodity chain (later global value chain) framework, originated by Gary Gereffi, to the question of who bears the ecological costs of production and consumption. Gereffi's insight was that globally dispersed production is organized into chains coordinated by lead firms, and that chains differ in their governance: producer-driven chains are steered by manufacturers, buyer-driven chains by retailers and brand owners who set prices, quality, and standards for their suppliers. Environmental analysts extend this by tracing a commodity from extraction through processing to consumption and attaching environmental loads, such as deforestation, emissions, and water use, to each node. Because the demand and the value capture often sit at the consuming end while the heaviest environmental burdens fall at the producing end, the method makes visible the geographic displacement of ecological costs that underlies global trade.	Telecoupling analysis is an integrated framework, introduced by Jianguo Liu and colleagues in 2013, for studying socioeconomic and environmental interactions between coupled human and natural systems that are far apart. As trade, migration, investment, species movement, and information flows increasingly link distant places, environmental change in one location is often driven by demand, decisions, and processes in another. The framework gives this distant coupling a common structure: it distinguishes sending, receiving, and spillover systems, and within each it identifies the flows that connect them, the agents who act, the causes that drive the interaction, and the effects that result. By making distant cause-and-effect explicit, telecoupling analysis lets researchers study phenomena such as land-use displacement, deforestation driven by foreign demand, and the global reach of conservation or development interventions as one connected system rather than as isolated local cases.
