Community resilience is the sustained ability of a community to use available resources (energy, communication, transportation, food, etc.) to respond to, withstand, and recover from adverse situations (e.g. economic collapse to global catastrophic risks). This allows for the adaptation and growth of a community after disaster strikes. Communities that are resilient are able to minimize any disaster, making the return to normal life as effortless as possible. By implementing a community resilience plan, a community can come together and overcome any disaster, while rebuilding physically and economically.
Community resilience planning
A community resilience plan is an action plan that allows for a community to rebuild after disaster. The plan should entail specific guidelines that will aid the community to rebuild both the economy and the ecosystem that the community thrives on. This typically means there are measures in place that a community will follow, such as the distribution of volunteers, and the access to knowledge and resources necessary to rebuild. Adaptability is a key attribute which means prevention can occur in response or before disaster strikes. The National Institute of Standards and Technology has a Community Resilience department tasked with solving this problem. This agency has created a Community Resilience Planning Guide, and its aim is to assist communities with anticipating challenges through a practical application that takes into account the social needs of the community as well as dependencies on the "built environment" - buildings and infrastructure systems. The outline of the six step process is shown below:
- Six-step process
- Form a collaborative planning team
- Understand the situation
- Determine the goals and objectives
- Plan development
- Plan preparation, review, and approval
- Plan implementation and maintenance
Classification of hazards
- Wind (hurricane, tornados)
- Earthquake (landslides, liquefaction)
- Inundation (flooding, coastal erosion)
- Fire (natural, manmade)
- Snow or rain (blizzards, tsunami)
- Technological or human-caused (cyberwarfare, nuclear weapons)
- Hazard events that occur regularly and are typically less consequential events in terms of damage and recovery.
- Hazard events that structures must be designed to withstand and often includes many natural disasters.
- Hazard events may also found in building codes for some hazards; however, they are likely to cause significant and often irreparable damage.
Dependencies and cascading failures
Infrastructure systems such as buildings, water, electric power, transportation, and communication are all interconnected and interdependent networks or systems. This means that a failure in one network can have catastrophic impact on another system. When Hurricane Katrina hit New Orleans, LA on August 23, 2005, it caused network outages in transportation and power networks which led to system failure and impedance in others such communication and emergency services.

Climate resilience can be generally defined as the adaptive capacity for a socio-ecological system to: (1) absorb stresses and maintain function in the face of external stresses imposed upon it by climate change and (2) adapt, reorganize, and evolve into more desirable configurations that improve the sustainability of the system, leaving it better prepared for future climate change impacts.With the rising awareness of climate change impacts by both national and international bodies, building climate resilience has become a major goal for these institutions. The key focus of climate resilience efforts is to address the climate vulnerability that communities, states, and countries currently have with regards to the many consequences of climate change. Currently, climate resilience efforts encompass social, economic, technological, and political strategies that are being implemented at all scales of society. From local community action to global treaties, addressing climate resilience is becoming a priority, although it could be argued that a significant amount of the theory has yet to be translated into practice. Despite this, there is a robust and ever-growing movement fueled by local and national bodies alike geared towards building and improving climate resilience.
