the proposed USGS program does incorporate cooperative projects with state and local agencies and with private industry, the committee believes that even greater emphasis is needed in this area.
A variety of approaches to establishing landslide inventories, with mapping forming an important but not the sole component, should be included in a national landslide hazard mitigation strategy.
The committee suggests that the proposed strategy would benefit from development of additional partnerships: with the financial community, as an important element for reducing financial loss caused by landslides; with educators at all levels; and with Canadian and Mexican authorities, both for mitigating risk that extends across national borders, and to promote mutually beneficial information exchange.
Landslide mitigation typically involves decisions at the local level, and a lack of information about landslide distribution and degree of hazard appears to be a major constraint to providing better mitigation in many areas. Informed decisions require adequate information concerning landslide mechanisms and mitigation alternatives, and this information must be available to all sectors of society. A national landslide hazard mitigation strategy must include extensive outreach, educational, and technology transfer components if it is to successfully address the diversity and breadth of landslide hazards.
In addition, the committee anticipates that salient issues to be addressed in its final report will include the following:
The status of the science of landslide processes and future research directions.
The role and application of landslide hazard susceptibility mapping and landslide monitoring.
Potential administrative structures to enable participation by the diverse range of stakeholders and partners in funding and implementation decisions.
Improved education and information transfer: for decision-makers to assist the regulatory environment; for planners, scientists, and engineers involved with landslide mitigation; and for the general public.
The role and application of risk assessment methods to the prioritization of landslide hazard mitigation activities.
