1.1. Rock Shelters at Risk

Welcome to the course ‘disaster recovery and build back better’. My name is Ram Sateesh. I am an assistant, Department of Architecture and Planning, Indian Institute of Technology, Roorkee. Today, I am going to discuss about a heritage component, how it is subjected to risk and how one can analyze from a very multi-disciplinary perspective and also how the conservation plan works along with the risk management plan.

In this introduction, we are learning about the focus of the lecture: rock shelters as important heritage components. The speaker emphasizes the need to analyze these shelters from various perspectives, especially regarding the risks they face and the plans for their conservation. This cross-disciplinary approach includes insights from architecture, history, and environmental management.

Consider a historical building that's been around for centuries. Just like we assess the structural integrity of a building to prevent collapse, rock shelters need to be evaluated for risks like erosion or damage from climate change to preserve their historical value.

So, this is about rock shelters at risk; and in the whole world if we look at the ancient man's shelter, the very basic form of shelter is the caves, you know the cave dwellings and the rock shelters. And different parts of the world still carry some evidences that how the earlier man have lived and some images of their paintings, there have been some images of their nomadic or pastoral life or hunting life you know.

Rock shelters are fundamental to understanding human history. They are some of the earliest forms of shelter that humans used for living, hunting, and other activities. These shelters provide invaluable insight into the lifestyles of ancient peoples, illustrated through paintings and artifacts found within them.

Think of rock shelters as the original open-air museums. Just like how we visit museums to learn about the past, rock shelters act as a window into the lives of our ancestors, showing us their daily activities and artistic expressions.

So, when you see at this image, I am not talking about as an historian, I am not talking about as an architect, I am talking from a risk perspective, how this heritage component subjected to risk and how one can look at from a multidisciplinary perspective.

The speaker highlights the importance of viewing rock shelters through a risk management lens. This involves understanding how environmental factors and human activities threaten these ancient sites. The idea is to incorporate different disciplines, such as history and architecture, to create a comprehensive risk analysis.

Imagine a team of experts working on a project to save an endangered species—biologists assess ecological risk, climate scientists analyze environmental changes, and policy makers create laws to protect the species. Similarly, rock shelters require diverse fields to secure their future.

when you look at this image, obviously one can notice that there has been some kind of liquid, lava or something which has been flown around this region and it has got settled down. And that is how from the Google Earth map you can see that the whole gradients and the slopes and aspects which are formed by the way it has been cool down.

The text discusses the geological context of rock shelters, particularly involving lava flow in the region, which shapes the environment around them. The formation of gradients and slopes impacts both the structural stability of the shelters and the ecosystems surrounding them.

Think of how heavy rain can create mudslides that might affect houses on a hillside. Similarly, the geological effects of past volcanic activity can reshape the land surrounding rock shelters, influencing both their safety and the habitats within them.

And if you go further closer and this is what we can see the Pitalkhora caves. This is in the Western Ghats in the Satmala range of the Western Ghats in Maharashtra state of India and in fact I want to give a credit of two important people like this is most of the information this has been from the source of Prabhakar Nandagopal.

The Pitalkhora caves are highlighted as a specific example of rock shelters located in India. The speaker notes its significance and acknowledges contributions from scholars who have studied these caves, emphasizing the importance of collaborative research in understanding these historical and architectural sites.

Just like how a collaborative project in school can bring together different skills—art, writing, research—studying rock shelters benefits from various experts sharing knowledge to uncover their historical significance.

If you look at the layout of a Buddhist site which is a Pitalkhora caves which is in the district of Aurangabad. Now, initially these sites goes back to almost pre 250 BC which is almost to the 3rd century BC as well and they are not done.

The layout and structure of the Pitalkhora caves are discussed, with references to their origins dating back to 250 BC. This historical timeline provides insight into the development of cave architecture and Buddhist practices over centuries. Understanding these historical contexts is crucial for appreciating the cultural heritage.

Imagine discovering an old diary from a family that details their life a hundred years ago. Just like the diary gives insight into past experiences, the layers of history at rock shelters like Pitalkhora reveal how people lived and evolved through time.
