Summary	The chain of explanation is the core analytical device of regional political ecology, introduced by Piers Blaikie and Harold Brookfield in Land Degradation and Society (1987). It treats an environmental outcome such as soil erosion not as a technical accident but as the visible end of a causal chain that runs from the individual land manager outward through the household, the regional economy, the state, and ultimately the world economy. Rather than blaming the farmer or the rainfall, the analyst follows the chain link by link to show how decisions on the ground are shaped by pressures and constraints set at much wider scales. The method is closely allied to Andrew Vayda's progressive contextualization, which begins with a specific human-environment activity and explains it by placing it in progressively wider contexts. Together these give political ecology a disciplined, scale-spanning way to connect local degradation to its political-economic roots.	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.
