Sikkim - Coggle Diagram
Sikkim
Resilient infrastructure
Slope stabilization techniques
Retaining walls
Rock bolting and netting
Improved drainage systems
Prevent water buildup → reduces landslides
Early warning systems
Flood and weather alerts
Raised bridges & stronger road design
Glacial lake monitoring
Satellite tracking of lake levels
Eco-friendly construction
Using local materials to reduce damage
Disaster risk
Frequent landslides due to steep terrain
Flash floods during monsoon
Risk of GLOFs (glacial lakes bursting)
Earthquake-prone (Himalayan seismic zone)
Road and infrastructure damage common
Impact & Benefits
Reduced landslide damage in some areas
Better disaster preparedness
Faster evacuation due to warnings
Improved road connectivity after repairs
Increased awareness of climate risks
challenges
Difficult terrain → construction is hard
High cost of resilient infrastructure
Remote villages lack strong protection
Climate change increasing risks
Monitoring systems not always fully effective
