“How can cities be designed to absorb water from floods instead of block it?”

 

With rising sea levels and rain penetration due to climate change, cities are looking for ways to adapt. Although the most popular methods typically involve building massive pieces of infrastructure such as sea walls, more natural ways to solve this are available. One innovative way is to remodel urban areas as Sponge Cities. Sponge cities are cities with large volumes of greenery that can absorb any torrent of water. These green spaces can range from gardens to green roofs to simple porous designs. Sponge cities not only make municipalities more resilient to climate change but also prevent discharge of polluted water, increases biodiversity, and improve quality of life.

How Prefabricated Housing Creates Resilience for Communities

“How does prefabricated housing create resilience for communities?”

 

Prefabricated housing represents a paradigm shift in the construction industry. No longer do projects have to rely on intricate designs and supply chains, now they are free to use a general template that can be replicated with ease. Not only is this more sustainable due to using fewer resources, but it also allows for greater resiliency in many ways. More houses can be built at a quicker rate for less investment, allowing for refugees to move in en-masse. These homes can also be built to the latest resilience standards, and parts can be easily replaced in case of a disaster due to their mass-produced nature. Finally, their simplified construction supply chain makes them less poised for disruption. This is How Prefabricated Housing Creates Resilience for Communities.

How to Build Resilience Against Fire-Inducing Winds

How to Build Resilience Against Fire-Inducing Winds

11/15/19

“How can we make our communities more resilient against fire-inducing winds?”

 

Strong winds have the potential to induce wildfires in hot dry climates. This threat will only be magnified by the transformed weather conditions induced by climate change. So how can we make our communities more resilient against these fire-inducing winds? Well, there are multiple ways of accomplishing this. First, more accurate weather prediction services can be developed so people can have a better sense of when strong winds are present. Another way is to develop microgrids connected to distributed energy resources to ensure a steady flow of electricity when the main grid has been shut down by the utility. Utilities can also underground transmission lines to insulate them against the effects of strong winds. These are only a few ways that we can think about How to Build Resilience Against Fire-Inducing Winds.

How the Increased Frequency of Droughts Will Put Pressure on City Water Infrastructure

11/03/19

“How will the increased frequency of droughts add stress to a city’s water infrastructure?”

 

As the climate is changing, more and more cities around the world will have to deal with the effects of drought. This means that less water will be available for municipal services, placing a strain on infrastructure. This effect can already be seen in cities around the world, whether it be Cape Town’s Day Zero crisis or Chennai running out of water. This is How the Increased Frequency of Droughts Will Put Pressure on a City’s Water Infrastructure.

Why Urban Heat Resilience Needs to Be Equitable

Why Urban Heat Resilience Needs to Be Equitable

“Why must equity take paramount importance when we design urban heat resilience?”

 

With the increase in average global temperatures and the densification of metropolitan centers, urban heat resilience will become a greater issue for the world. However, engineers and urban planners must keep in mind that the most vulnerable people in society, particularly seniors, young children, pregnant women, and people with disabilities and medical conditions will be the most susceptible to extreme heat. Resilience techniques that do not take these elements of society into account or ignore their needs will actively hurt them. For example, if all of the resources go to greening the wealthy districts of a city, then none will be left for people of lower-income areas. Since it is the duty of resilience professionals to ensure the safety of those most affected by climate change, it is only understandable Why Urban Heat Resilience Needs to Be Equitable.

Asset Resilience Prioritization

“How should we prioritize assets for resilience?”

Many institutions and communities all over the world have to deal with limited resources. And this applies to the world of resilience. Sometimes we will not be able to have enough backup power in the case of a large-scale power outage. As a result, different assets will have to be given different levels of priority of power. This Asset Resilience Prioritization is one of the most important parts of resilience planning and is necessary for every planner.
