Σύνοψη	Lifeline interdependency analysis studies how critical infrastructure systems — power, water, natural gas, telecommunications, and transportation — depend on one another, so that a disaster striking one can cascade into others. The foundational framework, set out by Steven Rinaldi, James Peerenboom, and Terrence Kelly in 2001, classifies the couplings among infrastructures into physical, cyber, geographic, and logical interdependencies and characterizes how disruptions propagate across them. Modeled as coupled networks, the lifelines and their dependency links allow analysts to simulate cascading failure: a power outage stops water pumping and telecommunications, transport disruption delays restoration, and feedbacks amplify the impact. The analysis estimates the system-wide consequences of disruptions and informs restoration sequencing, making it central to understanding why disasters disable far more than the directly damaged components and to planning resilient, recoverable infrastructure.	The Post-Disaster Needs Assessment (PDNA) is a harmonized, government-led methodology for quantifying the effects of a disaster and costing a recovery program. Agreed in 2008 by the European Union, the World Bank (through GFDRR), and the United Nations Development Group, and codified in the PDNA Guidelines, it fuses two traditions: the ECLAC damage-and-loss accounting (DaLA), which values destroyed assets and the economic flows foregone during recovery, and a human-and-recovery-needs assessment, which captures impacts on people's lives, livelihoods, and access to services. Conducted sector by sector against a pre-disaster baseline, a PDNA produces a single consolidated picture of total disaster effects and feeds a costed Recovery Framework that increasingly embeds build-back-better resilience, giving governments and donors a common basis for mobilizing and prioritizing recovery resources.
