Understanding Hazard Types
Unlock Audio Lesson
Today, we will explore the types of hazards we face. Hazards can be broad-ranging; can anyone tell me what they think natural hazards are?
Natural hazards are events like floods and earthquakes, right?
Exactly, great response! Natural hazards include serious events like earthquakes and floods. In addition, we also have non-natural hazards like smoking, which can lead to health risks.
So smoking is a risk because it can cause diseases?
Yes, that's correct! Smoking increases the risk of lung cancer, among other health issues. It's important to see how risks can come from both natural and human actions. Let's try to remember it using the mnemonic NERD: Natural, Environmental, Risks, and Diseases.
Disaster Risk in Asia
Unlock Audio Lesson
Now, let's discuss how disaster risk is particularly heightened in Asia. Why do you think that is?
Isn't it because a lot of people live in urban areas that are prone to disasters?
Exactly! By 2030, urban populations are projected to rise to 61.1%. This concentration increases the risk during disasters. This is important to remember through the acronym UBR: Urbanization Brings Risks.
So if more people are together, it makes evacuating harder during disasters?
Correct! And this is why increasing awareness and preparation is key. How can we promote risk awareness in communities?
Trends in Disaster Frequency
Unlock Audio Lesson
Let's talk about trends in disasters over the years. What has changed from 1950 to 2000?
There have been more disasters and economic losses, right?
Absolutely! Economic losses have significantly increased. To remember this, think of the phrase DDE: Disasters Developing Economically. What does this imply for future disaster risk?
It means we need to prepare better to handle these growing impacts!
That's exactly it! Understanding this data helps us recognize the urgency in disaster preparedness.
Preparedness Beyond Structural Measures
Unlock Audio Lesson
Next, we discuss why structural measures alone aren't enough. Can anyone give me an example of a structural measure?
Like building dams or dikes?
Right! While they are important, they don’t address community preparedness. We need people to recognize risks, which is where awareness comes in. Let’s remember this with the phrase ARK: Awareness Raises Knowledge.
So, knowing what to do during a disaster is just as important as having the right infrastructure?
Exactly! It's a crucial part of resilience.
Promoting Preparedness Measures
Unlock Audio Lesson
Finally, what are some ways we can promote preparedness in our communities?
We could encourage people to buy flood insurance?
Great suggestion! Flood insurance can help mitigate financial losses. Another measure could be installing rainwater harvesting systems.
And eco-friendly houses, right!
Exactly! Encouraging sustainable practices contributes to increased resilience. This can be remembered as SAFE: Sustainable Actions Foster Efficiency.

Hello everyone, we will discuss, welcome to this lecture series on disaster recovery and build back better. In this lecture, we will focus on risk perception and disaster risk preparedness, I will tell you that why we need. Also to focus on risk preparedness, not only in mitigation and also I will tell you what is the critical role of risk perception when we are trying to promote preparedness.
Detailed Explanation
In this introduction, the speaker sets the stage for the discussion on disaster recovery and the importance of understanding risks and preparing for disasters. They highlight that risk perception is crucial for promoting preparedness, which means that how we view and understand risks influences our ability to prepare for and respond to disasters effectively.
Examples & Analogies
Consider how people prepare for a storm. If someone perceives a hurricane as a serious threat, they are more likely to stock up on supplies and evacuate if necessary. This preparedness can save lives because the individual recognized the risk and acted accordingly.
Understanding Different Types of Hazards

We already know that we have many hazards including natural hazards okay, like flood or kind of volcano but also we have many other hazards which are not directly related to disasters but let us look at in a broader perspective, we could have smoking or GMO.
Detailed Explanation
In this chunk, the speaker describes various types of hazards. Natural hazards include events like floods and volcanic eruptions, while also mentioning non-natural hazards such as smoking and genetically modified organisms (GMO). This broader perspective is essential as it expands our understanding of risks that can affect health and safety in different ways.
Examples & Analogies
Think of smoking as a hazard that individuals may not immediately associate with disasters. While it doesn’t lead to a natural disaster, over time, smoking can lead to severe health issues like lung cancer, thereby presenting a risk that requires awareness and preparedness, similar to preparing for floods.

Now, looking at disaster risk, particularly in Asia that is for sure that Asia is one of the hotspot, it is one of the most disaster-prone region in the world.
Detailed Explanation
This chunk emphasizes that Asia is a highly disaster-prone region for both natural and man-made hazards. Due to geographical and population factors, cities in Asia are particularly vulnerable to disasters, making it critical to understand risk perception and preparedness in these areas.
Examples & Analogies
Imagine living in a community near a volcano. If you know the volcano has previously erupted and may erupt again, this awareness affects how you prepare your home, such as having an evacuation plan or an emergency kit ready, illustrating the importance of risk perception in vulnerable regions.
