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
