What is ISO 22327 about?
ISO 22327 gives guidelines for a landslide early warning system. It provides a definition, aims to improve understanding, describes methods and procedures to be implemented, and gives examples of types of activities.
ISO 22327 applies to communities vulnerable to landslides, without considering secondary effects.
ISO 22327 recognizes population behaviour response planning as a key part of preparedness.
Note: ISO 22327 considers the approach of ISO 22315 and provides additional specifications for landslides.
Who is ISO 22327 for?
ISO 22327 on security and resilience with guidelines for landslide early warning system is useful for:
- Emergency response bodies
- Highway road authorities
- Local authorities
Why should you use ISO 22327?
Landslides are one of the most widespread and commonly occurring natural hazards. Landslides may occur in different types of topographic and geologic settings. The occurrence of landslides may increase significantly due to uncontrolled land use development and human interference into unstable slopes. In many countries, landslides cause substantial socio-economical losses.
Landslide mitigation can be carried out both by structural and non-structural efforts. Structural mitigation includes adjustment of slope geometry, slope reinforcement, and protection and improvement of drainage systems, all of which require a high cost. The alternative option of relocation is not practical for residents living in areas prone to landslides. As a result, the most effective disaster risk reduction can be achieved by non-structural mitigation through the improvement of the community’s preparedness by implementing an ISO 22327.
The goal of ISO 22327 is to empower individuals and communities who are vulnerable to hazards to act in sufficient time and inappropriate ways to reduce the possibility of injury, loss of life and damage to property and the environment.
ISO 22327 for a landslide early warning system promotes uniformity in the development and implementation of early warning systems and will improve the preparedness of the communities vulnerable to landslides.
