9.3 Strategic framework for future work on landslides• Future work on landslide hazard must be done within a well-funded strategic framework.• The work already done by the Irish Landslides Working Group and reported in this publication should formthe basis or starting point for the future work.• The landslides hazard work should be continued within a multi-disciplinary framework led by the GeologicalSurvey of Ireland.• This multi-disciplinary approach would involve geologists, geomorphologists, geotechnical engineers,climatologists, planners, and those with GIS expertise.• The collaborators would include university researchers, local authorities, government departments andagencies such as Teagasc, and consulting geologists and engineers.• The funding necessary for the proposed work programme should be sought.92
