CHAPTER 4. PUBLIC AWARENESS AND ENVIRONMENTAL EDUCATION
4.2. Environmental Public Awareness
4.2.1. Tools of Public Awareness Development (suite)
One-way communication models (messages from the source to recipients)
are utterly useless in involving the public in decision-making processes.
Two-way communication models, providing the exchange of messages between
the source of information and its recipients are applied for this purpose.
The following can be differentiated:
- A two-way asymmetric model where responses are waited for in order to
improve the preparation of information so as to obtain strictly defined
and planned reactions of the "recipients".
- A two-way symmetric model where public response is monitored, based
on a compromise and negotiations; to a significant extent, the
asymmetric model rejects these techniques.
To recapitulate, the two-way symmetric model is most useful in the
public involvement process related to the decisions concerning protection
of waters in lakes and reservoirs.
- The mass communication process consistent with this model includes
the following stages:
- The first link is the source of messages.
- The second element of the process is the contents of messages
transmitted using various techniques (message vehicles).
- The last stage constitutes an assessment of response from
recipients (feedback).
As shown in Figure 4.2, mass communications is a closed process
consisting of several stages which should proceed successively and be
repeated many times until the decision for which it has been initiated is
implemented and sustainable environmental effects achieved.

Information Sources
Freedom of access to information on the environment is the basic step to
achieve satisfactory public involvement in the decision-making processes.
The sources of environmental information are decision-makers of
governmental, regional and local tiers, environmental protection agencies,
and research institutes.
Where the watershed of lakes and water reservoirs covers the territory
of several countries, all the above mentioned organizations from all those
countries shall become the source of information. The information must be
disseminated by technical experts, managers and politicians to focus
public attention on the problem.
Contents of the Environmental Information
The level of public environmental awareness depends not only on the
quantity and quality of information transferred to the public, but also on
the forms and means of its availability. The complicated language of
messages hinders their reception and understanding. In spite of necessary
simplification, the essence of the problem must be transmitted and
correctness of the subject matter maintained. The contents of a message
should be suited to the knowledge of the recipients. It is advisable to
refer information to the personal experience of the recipient. Information
must always be trustworthy and reliable.
