At the 6th Heads of Road Authorities (HORA) meeting in Seoul in May 2007, a Workshop on Disaster Risk Management was conducted and an Advisory Group was established to play a key role in managing regional disasters.
Following this meeting, the Advisory Group held its inaugural meeting in November 2007 in Malaysia in conjunction with the 84th Meeting of the REAAA Governing Council. It was agreed that the Advisory Group should be seen as the ‘voice’ in the region, and the focal point for other international agencies, in the area of disaster risk management. In line with this mission, the objectives of the Advisory Group were to:

  • share experiences/practices in the region with respect to road infrastructure disaster risk management
  • prepare a Compendium which reports current practice and lessons learned relating to road infrastructure disaster risk management
  • disseminate relevant information through workshops and publications.

In this Compendium on Disaster Risk Management, a summary is presented of the activities conducted to scope the contents of the Compendium and how natural disasters, and their effects on the road infrastructure, are managed in member countries. Some case studies have also been included.

A review of the countries represented in this Compendium – including location, geographic coordinates, land area, climate, terrain, natural hazards, administrative divisions, population and road length – revealed that:

  • land areas vary from less than 700 km2 (Singapore) to about 7,600,000 km2 (Australia)
  • geographic coordinates vary from 36º-37º north (Japan and Korea) to 41º south (New Zealand) and from 81º east (Sri Lanka) to 174º east (New Zealand)
  • the population varies from about 390,000 (Brunei) to about 240,000,000 (Indonesia)
  • government type varies from constitutional monarchy, republic and constitutional sultanate
  • the number of administrative divisions ranges from none (Singapore) to 76 provinces (Thailand) and 80 provinces and 120 chartered cities (Philippines)
  • the climate varies from arid to semi-arid, temperate, sub-tropical, tropical and even sub-arctic
  • the terrain varies from coastal plains, deserts, fertile plains and mountainous; sometimes, all of these features pertain to a single country
  • road length varies from about 3,500 km (Brunei, Singapore) to 800,000 km (Australia) and 1,200,000 km (Japan); the proportion of unsealed roads varies from 0% (Singapore) to about 90% (Philippines) and 95% (Papua New Guinea)
  • natural hazards include land subsidence, droughts, bushfires, cyclones/typhoons, landslides/mudslides, volcanic eruptions, earthquakes, tsunamis, flooding and avalanches.

From a socio-economic point of view, the population of some countries is increasing rapidly. There has been rapid economic growth (recently tempered by the world economic recession) and, in many cases, a large increase in urbanization. The need to provide new roads is a high priority in developing countries in the region whilst, in the developed countries, the emphasis is on managing urban congestion and maintaining the existing assets.
