1.2. Understanding Risk Communication

Risk communication is defined as any purposeful exchange of information about health, disaster, environmental risks between interested parties.

Risk communication involves a two-way interaction where information is intentionally shared to inform and influence behaviors and perceptions regarding health and environmental risks. This means that both parties—senders and receivers—play active roles in the communication process, aiming for a mutual understanding.

Think of risk communication as a conversation between a doctor and a patient about a health concern. The doctor (sender) provides advice and guidance (message), while the patient (receiver) processes this information to understand their health situation and make informed decisions.

Now we need to look that what are the challenges when we are sending the informations to the recipient in order to do something, in order to prepare, in order to enhance their capacity to prepare against the disasters.

Communicating risks effectively is fraught with challenges. These include understanding the complexity of the information, the potential misunderstanding of messages by the audience, and the impact of external factors like noise that can distort communication. This means that senders must be aware of how their messages might be interpreted and what barriers exist in helping recipients understand them.

Imagine trying to explain a fire evacuation plan in a noisy room. Even if your plan is clear, the sound of music or people talking can distract listeners, making it hard for them to pick up important details. This distraction represents the 'noise' that complicates effective risk communication.

There is one very typical model, very popular model, that was developed in 1940s on risk communications and that is most widespreadly used model in risk communications called Source message receiver model.

The Source-Message-Receiver model illustrates how information flows from the source (senders) to receivers through messages. In this model, the sender collects relevant information from credible sources, then encodes this information into messages before transmitting it through various channels (transmitters) to the receivers who decode the messages. This model emphasizes the steps involved in effective communication and highlights the potential barriers and enablers in that process.

Consider a weather warning about an impending storm. The meteorological agency (source) gathers data, formulates a warning (message), then it goes through news outlets like TV and radio (transmitters) before reaching the public (receivers). If the agency’s data is clear and the news outlets communicate it well, people will be prepared for the storm.

Now, the receiver also interpret decode and recode this message coming from the transmitter and it is also challenged by the question of noise.

Noise represents any disruption in communication that can lead to misunderstandings or incomplete information. This can be literal noise, such as sounds that distract people from listening, or figurative noise, such as pre-existing biases or misconceptions. It is essential for both senders and receivers to be aware of these potential disruptions to create more effective communication strategies.

Imagine trying to receive a text message while also listening to loud music. The distractions may lead to missing part of the important information. Similarly, in risk communication, if a person has preconceived notions about a disaster, it can affect how they interpret the important messages being conveyed.

If the transmitter cannot understand, they feedback this one to the original senders, and also the receivers if they have some questions, concerns, needs, they can also give feedback to the senders.

Effective communication is not just a one-way street; it involves a feedback loop where the transmitter and receivers can communicate their concerns or clarifications back to the sender. This feedback is crucial for ensuring that messages are understood and can help improve future communications. It helps bridge any gaps that may arise from misunderstandings or miscommunications.

Think of a teacher explaining a new concept in a classroom. If students are confused or have questions, their feedback helps the teacher adjust their approach. Similarly, in risk communication, if the public expresses confusion about a disaster warning, the authorities can clarify and provide additional information.
