Significance

• Water supply for cities, industry, irrigation.
• Hydropower (Dnipro cascade: Kyiv, Kaniv, Kremenchuk, Dnipro, Kakhovka dams).
• Inland navigation (Dnipro, Danube, Southern Buh).
• Biodiversity (wetlands, delta ecosystems, fish spawning).

Current Threats

War damage (Kakhovka Dam destruction 2023), pollution, climate change (droughts), and aging infrastructure challenge sustainable management.
