Greece is advised to enhance river flow space and defenses in the Thessaly plain to prevent future floods. Thessaly, contributing 25% to Greece’s agricultural output and 5% to its GDP, was severely affected by Storm Daniel’s record rains last year. A plan by HVA suggests moving dykes, deepening riverbeds, and restricting construction on floodplains. Despite potential water shortages due to groundwater extraction for irrigation, HVA recommends planting less water-intensive crops. Thessaly faces a 500 million cubic meter annual water deficit, expected to rise with climate change. The proposed plan, costing about 4.5 billion euros, aims to address flood risks and water scarcity, potentially enhancing Thessaly’s agricultural competitiveness. The government is reviewing the plan for implementation. HVA also proposes tripling Lake Karla’s size to support agriculture. Public consultation on these proposals ends on March 29.
