This Survey of Environmental Monitoring and Information Management Programmes of International Organizations is an up-to-date compendium of environmental monitoring, information management and harmonization programmes of international organizations, It has been prepared as an initial step in addressing the issue of harmonizing environmental information at the international level. This Survey is intended to be a brief, but thorough, overview of what is currently being done in terms of environment related activities. In light of the vast amount of work being done, world -wide, in the field of environmental data collection and management, this manual can only be seen as an overview and not as a complete list of all programmes which currently exist. Moreover, it must be seen, not as a project complete in itself, but as part of the creation of an inventory and meta-database containing information on work being done in the field of environmental information collection and management.
