New Approaches to Climate Adaptation: Drought After Flood, Is it too late?

On October 25, 2024, the WWF Hungary and the Hungarian Hydrological Society organized a very relevant event titled “Drought After Flood, Is it too late? Causes and Consequences of Changes in the Hydrological Cycle in Hungary”. Among the standout presentations was Szilvia Simon’s talk titled “Climate Adaptation from the Perspective of Groundwater”. 

Szilvia emphasized the critical role of a comprehensive approach in addressing water scarcity. She highlighted that effective water management must integrate both surface and subsurface solutions, tailored to the specific characteristics of the area. 

A key concept discussed in her presentation was the NaBa-MAR^® (Nature-based Managed Aquifer Recharge), which forms the core of the ClimEx-PE project. This approach involves the strategic use of subsurface spaces to store excess water for future use and extraction. Szilvia explained that MAR methods are closely linked to surface water retention strategies and must consider natural groundwater flow systems to maximize their benefits. 

Main messages of Szilvia Simon’s Presentation: 

• Complex Approach to Water Scarcity: Effective management requires combining surface and subsurface solutions, adapted to local conditions. 

• Impact of Groundwater Flow Systems: Surface water retention plans must account for the effects of groundwater flow systems. 

• Managed Aquifer Recharge (MAR): MAR involves using subsurface spaces to store excess water for later use. Various MAR methods are closely connected to surface solutions. 

• Natural Groundwater Flow Considerations: Designing MAR systems with natural groundwater flow in mind can lead to more sustainable and nature-based solutions. 

Szilvia’s presentation underscored the importance of integrating natural processes and innovative techniques to develop resilient and sustainable water management practices. Her insights contribute significantly to the ongoing efforts of ClimEx-PE in promoting climate adaptation and water resource sustainability.
