Building a Disaster Resilience City

The eleventh goals are ”Make cities inclusive, safe, resilient, and sustainable”

In ten targets,

11.5　

"By 2030, significantly reduce the number of deaths and the number of people affected and substantially decrease the direct economic losses relative to global gross domestic product caused by disasters, including water-related disasters, with a focus on protecting the poor and people in vulnerable situations"

and could contribute to the 11.5 targets for heavy rainfall disasters.

• Check hazard map from the stage of selecting place

  First, use hazard maps to identify disaster risks for the land on which the house is to be built.

• Building a house that prevents flooding above floor level

  As explained earlier, flooding above floor level means flooding above the floor. It is said that the degree of damage varies greatly depending on whether the floor is flooded above the floor. To prevent flooding above floor level, it is important to take physical measures to prevent water from entering the house. The four key points are as follows

  

  • Fill the entire site to raise the ground level of the house.
  • Raise the floor position, such as in a pilotis structure
  • Surround the site with a waterproof fence, etc
  • Surround the building itself with waterproof building materials, etc.

  Therefore, damage can likely be minimized by considering measures to prevent water intrusion at the house construction stage. When I visited Australia, most houses were built on stilts. Therefore, I felt that my house would not likely be damaged even if a heavy rain disaster or flood occurred.

  

• Place electrical outlets in high locations
• Install outdoor units of air conditioners, water heaters, etc. above the expected water level.
• Install water facilities

and other measures to limit damage in the event of flooding. Other house designs are being developed that incorporate watertight windows, waterproof roofs, deep eaves, and other features.

One of the causes of frequent heavy rainfall disasters is climate change due to global warming. Environmental considerations are also essential in urban development.

• 3R
• Saving Energy
• Use of renewable energy
• Use eco-friendly car to reduce emission
• Equipment, buildings, and homes with reduced emissions and energy consumption from heating and cooling
• Solar and wind power generation
• Reduction of waste and waste loss

We need to create a low-carbon city that reduces CO2 emissions while circulating resources as we mentioned above.
