Disaster Recovery and Build Back Better
In this section, Prof. Subhajyoti Samaddar from the Disaster Prevention Research Institute at Kyoto University emphasizes the crucial role of social networks in disaster preparedness. The lecture begins with a recap of previous discussions about disaster preparedness, focusing on how social networks contribute to the collection of critical information for disaster management.
Using a case study from Bangladesh, the challenge of drinking water contaminated with arsenic and salinity is presented. The innovative solution proposed is harvesting rainwater at the household level, which can sufficiently provide drinking water for families during dry seasons. To promote this idea effectively, it requires extensive community engagement and the sharing of experiences through social networks.
Prof. Samaddar identifies three types of information needed for individuals to adopt these innovations: hardware and software knowledge acquired through observation, subjective knowledge through discussions, and general knowledge from various sources. The discussion points out the challenge people face when introducing new technologies, as environmental, social, and familial contexts heavily influence adoption decisions.
The section further examines how social networks serve as channels for disseminating essential information and reducing uncertainties in decision-making. By collecting opinions and experiences from a variety of contacts, individuals can make informed choices about implementing disaster risk management strategies. The importance of diverse network connections, including weaker ties, is also discussed, as these can provide fresh perspectives and information.
In conclusion, the lecture stresses that social networks not only facilitate knowledge transfer but also foster a sense of social obligation and pressure, motivating individuals to adopt preventive measures in disaster management.

In Bangladesh, we said that this is a beautiful country, they are battling with drinking water risk. The reason is that they cannot drink arsenic water, groundwater because it is arsenic contaminated, on the other hand, they have a problem of water salinity that is surface water they cannot drink. Because they are salty, they get waterborne health diseases, dysentery, diarrhoea, cholera, and many other problems.
Detailed Explanation
The speaker describes the significant challenge faced by the people of Bangladesh regarding drinking water. Groundwater is contaminated with arsenic, while surface water is saline, making both sources unsafe for consumption. This situation leads to health issues, including waterborne diseases. Understanding this context is critical for implementing effective disaster recovery and preparation strategies.
Examples & Analogies
Think of a household that relies on a well for water supplies. If the well water is contaminated, and they have no other options, they face serious health risks. Similarly, the people of Bangladesh are put at risk due to their water sources, highlighting the importance of finding innovative solutions to ensure safe drinking water.
Innovative Solution: Rainwater Harvesting

One possible potential idea, technology, innovation is that we can collect rainwater. We can collect the rainwater at the domestic level at the household level and preserve it in a tank. A tank of 5000 litres can easily provide a family of five members drinking water for six months during the dry season.
Detailed Explanation
Rainwater harvesting is presented as an innovative solution to the water crisis in Bangladesh. By capturing and storing rainwater at the household level, families can secure a sustainable drinking water supply. The speaker emphasizes the feasibility of this solution, indicating that a 5000-litre tank can serve a family during periods of little rainfall.
