Shrnutí	Land-use and land-cover change (LUCC) analysis is the land-change-science method for detecting how the Earth's surface is being transformed and explaining why, with particular attention to the social drivers behind the change. Its defining move, formalized by Eric Lambin and Helmut Geist, is to separate proximate causes, the direct human activities such as agricultural expansion, wood extraction, and infrastructure that physically alter land cover, from underlying driving forces, the demographic, economic, technological, institutional, and cultural factors that operate at a distance and push the proximate causes. Their meta-analysis of tropical deforestation showed that single-factor explanations are rare and that change is usually produced by synergistic combinations of drivers. The analysis chains remote sensing of cover change to a structured causal attribution, giving social scientists a rigorous way to link maps of deforestation or urbanization to the human forces that produce them.	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.
