Workshop 6 (synthesis): linking between flood risks and land use changes

Area of Science:

• Environmental Science
• Hydrology
• Urban Planning

Background:

• Land use changes, particularly deforestation, are increasing global vulnerability to flooding.
• Effective flood risk assessment and prevention strategies require detailed local knowledge.
• Existing flood management infrastructure and engineering measures face challenges from extreme flood events in large catchments.

Purpose of the Study:

• To highlight the critical role of local context in flood risk assessment.
• To emphasize the necessity of tailored flood prevention measures.
• To underscore the limitations of current flood management strategies against extreme events.

Main Methods:

• This study synthesizes existing research on land use change and flood dynamics.
• It analyzes the relationship between local environmental factors and flood vulnerability.
• Case studies of flood events in large catchments are reviewed.

Main Results:

• Local land use patterns significantly influence flood susceptibility and severity.
• A lack of detailed local data hinders the design of optimal flood prevention measures.
• Extreme hydrological events can exceed the capacity of both natural landscapes and engineered flood defenses.

Conclusions:

• Integrated approaches combining local ecological knowledge and engineering are vital for flood resilience.
• Future flood management must adapt to the increasing frequency and intensity of extreme events.
• Further research into localized flood dynamics is essential for effective adaptation strategies.
