Solutions for local regional national scale rational landslide risk assessment and management

Jun 5th, 2014

Riskope’s experts have worked since the ’80s in landslides assessment and in particular for Solutions for local regional national scale rational landslide risk assessment and management . Indeed, F. Oboni was the head geotechnical researcher of a Federally funded Swiss Landslide research team that developed internationally recognized pioneering work.

F. Oboni was also a member of a committee of IUGS that literally wrote the first glossary for Landslide Risk Management at the end of the ’90s. This long practice with landslides and other geo-hazards in various continents:

  • Europe
  • North America
  • Latin America (Peru, Chile, Brasil)
  • Central America (Mexico), 
  • Africa (Gabon, Ghana, Madagascar), 
  • Oceania.

has helped developing specific methodologies for regional/national landslide risk assessment, mapping and management.

Riskope regularly gives seminars and animates workshops in G8 and developing countries on the theme of landslides’ and other geo-hazards risk management.
In fact, Riskope also masters the various aspects of risk communication and crisis response having participated in:

  • public hearings, 
  • mediation and having prepared 
  • evacuation plans and disaster resumption plans.

Riskope provides guidance in discerning between “fast developing, one time” events or the probability of an acceleration when dealing with large, slow creeping extant failures. The distinction is vital for guiding the allotment and planning of sustainable and reasonable civil protection measures.

Geohazards Consequences are dealt in detail and a framework to undertake a holistic consequence analysis, including human health and safety, infrastructures, direct and indirect impacts has been developed. Regional governements and other entities have indeed to develop awareness for domino effects (cascading consequences) generated by landslides and societal tolerance.

Risk representation

Risk representation including modern and innovative techniques, is compatible with ISO 31000 principles and the studies are compatible with:

the new ISO 55000 (asset management) and
ISO 22301 (Societal Security – Business Continuity Management System) codes.

Crisis potential, communication requirements and preparedness plans are tackled including alert criteria and their implications on civil protection.

Landslide prioritization concepts are defined, using societal acceptability thresholds. This leads to showing that some risks:

  • are tolerable, 
  • others can be mitigated, and 
  • some may require strategic shifts in region’s management and land use, as they fall in the “unmanageable” category.

In addition to proper prioritization it is critical that clear records of risk management decision are kept for generation to come. Additionally rational decision making gives a much needed protection to the decision maker in case of accidents.
