Introduction to DRR Guidelines
Unlock Audio Lesson
Welcome everyone! Today, we're starting with the basics of Disaster Risk Reduction or DRR. Can anyone tell me why guidelines are essential for built environment professionals?
To ensure that buildings and structures are safe from natural disasters.
Exactly! These guidelines help us make informed decisions to protect communities. DRR manuals are focused on what to do and what not to do during the recovery process. Can anyone suggest why these are important for architects and engineers?
They provide practical, actionable insights that can save lives.
Absolutely! They make complex technical information accessible to all. Remember, we want these guidelines to serve as a roadmap for everyone affected by disasters. Let’s keep this in mind as we explore specific examples soon.
Dos and Don'ts in Shelter Practices
Unlock Audio Lesson
Now, let’s dive into some dos and don’ts in building practices. Can someone share a 'do' that is crucial when building in earthquake-prone areas?
Avoiding asymmetrical building designs?
Spot on! Asymmetrical designs can lead to torsion during earthquakes. What about a 'don't'?
Don’t use filled soil for foundations!
Exactly! Such practices can create instability. Always ensure that foundations are on stable soil. Keep these principles at the forefront as we continue.
Structural Recommendations
Unlock Audio Lesson
Let’s talk about the structural guidelines that can help us build safer. Who can give me an example of a structural recommendation from DRR?
Keeping the height-to-width ratio less than four for buildings?
Right! This ratio helps in maintaining stability. What about wind resistance for structures in cyclone-prone areas?
Buildings should have streamline designs to reduce wind resistance.
Great point! Using materials and designs that reduce wind load can significantly enhance building performance. Remember, understanding these factors is key to effective and safe design.
Multi-Hazard Considerations
Unlock Audio Lesson
Now, let’s consider how different hazards affect planning. Why do we need to think about more than one hazard when designing buildings?
Because a location might be vulnerable to multiple types of disasters like earthquakes and floods.
Exactly! It’s essential to assess risk holistically. For example, in Tamil Nadu, areas can be prone to both cyclones and earthquakes. What can we do to prepare against both?
We can design flexible structures with safe materials that can withstand both earthquakes and high winds.
Correct! Flexibility in design is key to resilience against varying forces from different disasters.

Guidance to DRR
This section serves as an introductory lecture by Prof. Ram Sateesh Pasupuleti, focusing on guidelines and principles for Disaster Risk Reduction (DRR). The content highlights the necessity of providing clear and accessible guidance tailored towards built environment professionals such as architects and civil engineers engaged in disaster recovery, particularly in humanitarian contexts. The lecture discusses manuals outlining various dos and don'ts applicable across different disaster scenarios, such as earthquake resistance design and floodplain considerations.
A significant emphasis is placed on how past guidelines were often too technical, hindering wider understanding among affected populations. Recent improvements have introduced a more visual and easily comprehensible approach that reaches vulnerable groups, such as those in remote rural areas. The section conveys that DRR guidance—developed based on evidence and field research—includes recommendations for structural practices to mitigate risks associated with earthquakes, floods, and other natural disasters. For instance, it advises against asymmetrical building forms in earthquake-prone areas, discusses site selection based on geographical risks, and outlines principles for reinforcing structures to withstand disaster forces.
The section ultimately stresses the importance of holistic planning that considers multiple hazards and advocates for making building regulations align with DRR guidelines to ensure safer, more resilient communities.

Welcome to the course; disaster recovery and build back better, my name is Ram Sateesh, I am Assistant Professor in Department of Architecture and Planning, IIT Roorkee. Today, we are going to discuss about guidance to DRR; Disaster Risk Reduction so, here today in this lecture what I tried to do is I tried to compile at least showcase, different kinds of manuals or which is providing some guidance.
Detailed Explanation
In this lecture, the speaker introduces the topic of Disaster Risk Reduction (DRR) and emphasizes the importance of guidance in recovery practices after disasters. The section highlights that various manuals exist that provide helpful instructions, best practices, and recommendations for professionals involved in disaster recovery. The guidance can vary from basic rules of thumb to more elaborate dos and don’ts tailored to specific disaster scenarios.
Examples & Analogies
Think of disaster recovery as similar to following a recipe when cooking. Just like a chef refers to a recipe for guidance on ingredients and steps, professionals engaged in disaster recovery refer to guidelines and manuals to ensure safety and effectiveness in rebuilding efforts after disasters.
Target Audience for Guidance

It could be a thumb rule guidance, it could be dos and don’ts, whatever you call it but it is showing some guidance; guidance to what, guidance to whom and guidance to which context so, when we say guidance to whom, this could be for the people who are working on the shelter practices whether it is an architect, whether it is a civil engineer, whether; so basically there is a group of built environment professions involved in the shelter recovery especially, in the humanitarian context.
Detailed Explanation
The guidance provided in DRR manuals is directed at various professionals involved in shelter recovery, such as architects and civil engineers. This section stresses the importance of targeted guidance for specific contexts, meaning that advice can differ based on the disaster type (earthquake, flood, etc.) and the professionals' roles in recovery efforts.
Examples & Analogies
Imagine if you're assembling furniture; you would want the instructions not only to tell you how to put it together but also to be suitable for different types of furniture like bookshelves or desks. Similarly, DRR guidance is tailored for specific professionals who deal with different aspects of disaster recovery.
Generic Principles of Disaster Recovery

And the second aspect is; it is talking about certain principles of do's and don'ts, you know what to do and what not to do which is better, it’s a very generic principles which is showing, it is not specific to the site but it will actually show some guidance to people working either on hilly areas or floodplain areas or an earthquake-prone area so, it is sometimes it is also specific to a disaster.
Detailed Explanation
This part discusses the general principles of disaster recovery which serve as do's and don'ts for building professionals. These principles are not always site-specific, allowing them to be applicable across different types of disaster-prone locations, including hilly terrains and floodplains. However, they can also be tailored for specific disasters to enhance their relevance.
Examples & Analogies
Consider the safety guidelines that apply to various types of sports, like wearing a helmet while biking or rollerblading. Though these guidelines may not be site-specific, they are broadly applicable to keep athletes safe across different environments.
Improvement of Manuals for Accessibility

So, this particular manuals earlier, they were too technical to work on it and but as the time moved on, the visual aspect has improved quite a lot and because it has to reach to the common man, the most of the target group population who were often affected by the disasters, they are probably from the vulnerable areas especially, from the remote rural areas where you hardly get any technical manpower.
Detailed Explanation
Historically, manuals for disaster recovery were often too technical for the average person to understand. However, over time, there has been a concerted effort to make these manuals more visually engaging and simpler to understand, ensuring that they can be accessible to the common man. This is especially important for individuals in vulnerable communities who may lack technical expertise.
Examples & Analogies
Think of how user manuals for electronics have changed over time. Earlier manuals might have been filled with jargon and complex diagrams, making it hard for someone unfamiliar with technology to use them. Now, they often include clear images, step-by-step instructions, and simpler language, making them easier for everyone to follow.

So, how this kind of guidance can show and these manuals can show your direction for the layman even to understand that what to do and what not to do and how to do, I will be showing a few guidelines and which has been developed by different agencies and what are the focus lights on and how they have tried to demonstrate and what is that they are trying to give an information or to a guidance to the shelter makers.
Detailed Explanation
The speaker intends to provide specific examples of guidelines that have been developed by various agencies. These examples will help illustrate how manuals guide individuals in disaster recovery by providing practical advice on construction and safety measures, which can be comprehended by the average person.
Examples & Analogies
It's like learning to ride a bike. You might first learn by watching a demonstration, which provides specific tips and guidance on how to balance, pedal, and steer. Manuals on disaster recovery similarly aim to demonstrate practical actions that shelter builders can take to ensure safety.
