ECOSYSTEM APPROACH TO FLOOD RESILIENCE

10-11 May, Vigyan Bhawan, New Delhi, India

• Dr. Shiraz A. Wajih• Dr. B.K. Singh

Location Map

• Change in time, volume, pattern etc.• Increasing frequency of flash floods• Smaller rivers- major causes• Dry spells during monsoon• Hot winds during winters• Increasing duration of water logging

Maintaining open spaces

Resiliency in Flood affected area to be developed through :

Criteria Examples

Redundancy Diversity : Livestock, agriculture

Flexibility Robustness of Farm System, Drainage

Responsiveness Time & Space Management in Cropping System

Capacity to learning ITK, experiment etc

Multi-tier cropping

Thanks!
