The aim of the Compendium is to provide information and guidance on how to assess and address the risks posed by sand and dust storms and plan actions to combat sand and dust storms. The Compendium brings together information and guidance from a wide range of sources. It includes approaches and methodology frameworks on data collection, assessment, monitoring and early warning, impact mitigation and preparedness, and source mapping and anthropogenic source mitigation that are required in the development and implementation of policies related to sand and dust storms at sub-national, national, regional and global levels, taking into account the principles set out in the Policy Advocacy Framework for Sand and Dust Storms, and the cross-sectoral and multidisciplinary nature of the impact that sand and dust storms can cause to societies, economies, and the environment.
