Information Sources and Dissemination

Free and open access to information about the environment is a basic step to achieve satisfactory public involvement in the decision-making processes. The sources of environmental information are decision-makers in government, environmental protection agencies, research institutes, non-governmental organizations and local inhabitants. Where the watershed of a lake or reservoir includes the territory of several countries, the relevant parties in all the countries should be encouraged to share their information.

The information should be addressed to the society at large. The basic tool of mass communication is a public involvement plan that provides a community-specific plan for interacting with a community regarding the permitted or corrective action. A public involvement plan includes the following components:

  • Assessment of the public awareness level.
  • Strategy of communication.
  • Identification of particular social groups and stakeholders.
  • Development of techniques for mass communication.
  • Analysis of probable barriers in the implementation of the communication process, such as available funds, equipment, staff, and skills.
  • Measures of assessment of the communication plan's implementation.
