lesson_2021: "No alert reached Verviers authorities before 14 July; only 17.5% of affected Ahr residents got an evacuation instruction; BE-Alert misses people with no or switched-off phones, and the 2021 peak hit many valleys at night.",

what: "Protect critical infrastructure (hospitals, power, drinking water, telecoms) and line up alternative supplies and reinforcements (civil protection, army, boats, helicopters) before the peak.",
lesson_2021: "Responders in Limbourg (BE) lost power and communication; Eschweiler hospital lost water and power and ICU patients were flown off the roof; Pepinster lacked reinforcements and a rescue boat capsized.",

id: "ST-AI",

pillar: "Anticipation of crises",
title: "Responsible AI for detection, monitoring and against fake news",

Policy {
id: "ST-CRISIS",
horizon: "short",
pillar: "Coordination of responses",
title: "Coordinated crisis management",
what: "Crisis response led by public authorities with private companies and households, with clear roles and aligned warning levels across municipalities and borders.",

id: "ST-EVACAPP",
horizon: "short",
pillar: "Coordination of responses",

what: "Give each resident the fastest evacuation route, let users report blocked roads, and show the capacity and occupancy of each shelter.",
lesson_2021: "Flash floods in small valleys (Vesdre, Geul, Inde) give very little warning, so plans must fit a short window; preventive evacuation along the Meuse (12,000 people in South Limburg) worked where water rose slowly.",

title: "Post-crisis recovery plans",
what: "Prepare recovery plans (compensation, reconstruction, restoring defences) before the next event.",
