What is Resilience?
According to Christopher Burton, resilience is defined as:
“ ...measurement of a system’s capacity to absorb disturbances and to reorganize into a fully functioning system following an event. This focus includes an understanding of a system’s capacity to return to the state (or multiple states) that existed before a disturbance.”
In the context of natural disasters, resilience refers to a person or community's ability to rebound after a disaster. Leaders often use this definition to mobilize support for reconstruction efforts. Resilience calls on typical American values such as hardiness, independence, ambition, and resourcefulness.
Because there are many different definitions of resilience, the topic raises many questions. How is resilience measured in a community? What are the components of disaster resilience? How do the media and a community's attitude affect resilience? What does resilience look like in a community? These are the questions I aim to answer.
Components of Disaster Resilience
PLAN MAKING PROCESS
- Organize: gather a team of core stakeholders
- Connect: involve as many community members as possible in the planning process
- Assess: collect data to use as the foundation of decisions
- Envision: engage the public in setting hazard mitigation goals
- Prioritize: identify policies and actions that align with other strategies
- Implement: identify manageable tasks and responsible parties
- Monitor, evaluate, and update: create feedback looks to adapt to changing conditions
DISASTER PHASES
- Hazard Mitigation: efforts taken before a disaster to reduce risk. Structural mitigation includes engineering solutions such as reinforcing dams, levees, and seawalls. Nonstructural mitigation includes policy-related solutions and preserving the natural environment
- Disaster Preparedness: Taking steps so that a community can respond before, during, and after a disaster.
- Disaster Response: this phase begins with the detection of the disaster and ends when the situation stabilizes after impact. It is an activation of preparedness plans
- Disaster Recovery: actions taken to repair and rebuild damaged property and restore community and economic activities
POST DISASTER PHASES
- Emergency period (search and rescue and sheltering)
- Restoration (repairing and restoring utilities)
- Reconstruction (restoring infrastructure and providing housing)
- Betterment Reconstruction
PREDICTORS OF RECOVERY SPEED
This section describes which factors in six categories impact how quickly a community recovers from a natural disaster.
Social Component
- % of non minority population
- % of population with at least a high school diploma
Economic Resilience
- Per Capita income
- % of homeowners in population
Institutional Resilience
- Having a hazard mitigation plan
- Participating in the National Flood Insurance Program (NFIP)
Infrastructure Resilience
- Housing density
- Non mobile homes
- Presence of primary and secondary school
Environmental Component
- %’s of land that that is swamp, marshland, wetland, or dunes
- % land area with no wetland decline
- % land area with no land use were predictors
HAZARD EXPOSURE
Hazards can be predicted in specific areas based on geographical location and past hazards a community has been exposed to. For example, communities on the east coast of America can determine how much risk they face from storm surges and winds during a hurricane using mapping tools and records of previous hurricane damage.
PHYSICAL VULNERABILITY
Physical vulnerability refers to buildings, infrastructure, and the natural environment. Assessing the risk of damage to buildings is done by looking at building codes, heights, and foundations. Infrastructure can be monitored and routinely updated reduce the loss of essential services. Protective natural features (including barrier islands, dunes, and wetlands) can be preserved through land management policies.
SOCIAL VULNERABILITY
Social vulnerability refers a person or groups ability to prepare for, endure, and recover from disasters. Vulnerable groups often lack access to information and necessary resources.
INDICATORS OF SOCIAL VULNERABILITY
- First order indicators show vulnerable groups in the community and which resources the community is lacking.
- Second order indicators group first order indicators into categories.
- The third order indicator represents the community's overall vulnerability.
How does a Community's Attitude Effect is Behaviors during a Disaster?
A study performed by Blendom et. al. considered the responses of people to Hurricanes Rita and Katrina in areas outside of their main impacts. Their goals were to determine how prepared people in the study group thought they were for the storms and identify factors that influenced people to not evacuate. After collecting data through telephone interviews, they found the following results:
These results how a community's mindset impacts their resilience. In the four areas surveyed, less than 50% said they evacuated before the hurricanes. Afterwards, the majority of respondents said that they would evacuated. The study found similar results across nearly every category and area of study. After the community was damaged by Hurricanes Rita and Katrina, they reevaluated their resilience and collectively decided to better prepare for the future.
How does the Media Affect Disaster Response?
After Hurricane Katrina devastated New Orleans and other areas along the Gulf Coast, Raymond Taras evaluated Cuban and Mexican responses to the US government's response by how each country's newspapers reported on the event.
This paper shows how media plays an important role in guiding the public's impression of a natural disaster. Cultural stereotypes are often reinforced through media framing. Media framing helps justify actions taken by leaders after the disaster and promote national pride.
“To frame is to select some aspects of a perceived reality and make them more salient in a communicating text, in such a way as to promote a particular problem definition, causal interpretation, moral evaluation, and/or treatment recommendation for the item described"
Mexican Newspaper Responses
Immediately after Hurricane Katrina hit, Mexican newspapers portrayed their government as more effective than America's in disaster response. This frame was backed up by the aid Mexico sent to Texans after the hurricane.
The newspapers were highly critical of the Bush Administration and compared his response to that of former Mexican president Miguel de la Madrid's insensitive response to a 1985 earthquake. They sympathized with local leaders in New Orleans, framing them as victims of their government's incompetence.
An important aspect of newspaper coverage was racial framing. Reporters highlighted hispanic efforts to rebuild after the hurricane despite racist comments directed at them by New Orleans officials. Mexican natives and hispanics in America were hailed as the backbone of restoration efforts who suffered greatly from racial biases.
Cuban Newspaper Response
Cuban newspapers framed the disaster as a comparison between Cuban and American ideologies. The country's national newspaper, Granma, reprinted American critiques of the federal response to Hurricane Katrina emphasize the American government's failures. The publication also juxtaposed the American relief effort after Hurricane Katrina with the war in Iraq. It questioned how the federal government had the funds to fight overseas but not to help its own people. Like Mexican newspapers, Cuban ones highlighted the racial tensions Hurricane Katrina exasperated in New Orleans.
Other Cuban newspapers echoed what was printed in Granma and emphasized the disorder and chaos of America's relief effort. Capitalism and imperialism were targeted as the main culprits of this failure, further aggravating ideological tensions between Cuba and America.
Resilience in Action
The Cuban response to Hurricane Irma shows the components of resilience in action. The category 4 storm affected 12/15 Cuban Provinces and resulted in only 10 deaths. The steps Cubans take during each disaster phase are prime examples of resilience in action. While Cuba has the benefit of a highly centralized government, similar results can still be replicated in the United States
Disaster Phases
The best example of hazard mitigation in Cuba is its decentralization of its power grid in 2005. Doing this prevented widespread power outages during Hurricane Irma and enabled power to be quickly restored to the 11.5 million citizens who lost it. Data from previous disasters also plays a role in planning and preparing for future disasters.
Preparedness plays a large role in disaster planning. Citizens participate in emergency drills from a young age and are encouraged to participate in local community meetings concerning disaster preparedness.
Healthcare workers are the core of Cuban Disaster response. Before the storm, 9,344 hospital beds were made available before the storm and healthcare workers were sent to evacuation shelters in advance.
After Hurricane Irma, there was an estimated 13 billion USD in damages. As a part of its disaster recovery efforts, the government paid partial reconstruction costs, provided subsidies up to 50% for purchasing building material, and helped survivors secure loans to rebuild their homes.
Resilience over Time
James Mitchell provides a review of disaster resilience in New Jersey over the 20th century. This review shows how communities can adapt to new and existing hazards to become more resilient.
EXPOSURE TO HAZARDS
Exposure= measure of the population at risk
New Jersey's population grew by 447% during the 20th century, with greater amounts of people more densely populated high risk areas. Larger populations put more people and infrastructure at risk for damage from natural disasters, especially along the coast. New Jersey's four oceanfront counties had a population growth of 916% that was characterized by the population of barrier islands and wetlands.
RESISTANCE TO DISASTER
During the 20th century the hazards that were the biggest threats to New Jersey have shifted. This is due to new hazard mitigation and response practices and changing demographics. Examining the how New Jersey adapted to these threats provides a blueprint on increasing resilience and how hazards and responses to them change over time.
Resistance= effectiveness of existing hazard mitigation measures
Forest Fires in NJ
In 1900 forest fires were a fact of life. The state had no organized warning system or evacuation plans. Response and recovery were organized by volunteer firefighters and local communities. By 2000 major changes reduced vulnerability to forest fires. The state established the Forest Fire Service, composed of paid and volunteer firefighters. Personnel were trained and given appropriate tools. Forests fire warning systems were also improved. First there were watchtowers to monitor high risk areas and eventually mapping systems and wildfire models were used to determine risk. These changes did not completely eliminate vulnerability, however. Economic shifts caused more people and capital to move to the peri-Pineland area which is especially prone to forest fires.
Responses to Coastal Storms
In 1900, New Jersey's coast was much less populated than it is today. Storm warning systems along the coast mostly helped offshore seafarers and fisherman. As the coastal population grew, the state's priority shifted to protecting onshore residents and infrastructure. In the 1970s evacuation routes and sirens became commonplace. A system of training and planning for coastal storms was established along with plans for sheltering and rebuilding after storms.
Hurricane Preparedness in Cape May County, NJ
The following provides examples of how disaster planning and community resilience functions in local communities.
Plan Making Process
Hazard Exposures
Cape May County is especially vulnerable to flooding, coastal storms, hurricanes, and wildfires. Hazard mitigation efforts have lessened the likelihood of wildfires in the county, but the other hazards are still threats.
Physical Vulnerabilities
In Cape May County, multiple barrier islands along the coast are heavily populated. Beach resorts are a major tourist destination and almost half of the buildings in the county are in high risk areas for flooding. Rising sea levels are also a concern for those living and working on barrier islands. Local shore communities adhere to strict building codes and and often fortify dunes on the beaches to limit vulnerability.
Social Vulnerabilities
The following maps show Cape May County's overall social vulnerability index in 2010 and that index broken down into four components of social vulnerability.
Social Component
This map shows the indicator of foreign-born population by county. A closer look shows that Cape May County as a relatively foreign-born population. This could indicate a quicker recovery after a natural disaster because non natives often are not given necessary resources or information to prepare for and recovery from disaster.
The predictor of people with at least a high school diploma, however is low compared the the rest of the state, indicating a slower recovery speed.
Economic Resilience
Data was not available for the county's average income, but average income for the state is relatively high, indicating a quicker recovery speed.
Institutional Resilience
As was mentioned about, Cape May County has a robust hazard mitigation plan, which is an indicator of a quicker recovery after a disaster. The chart below listing 1st and 2nd order indicators shows that Cape May County has a lower proportion of mobile homes than the rest of New Jersey.
Infrastructure Resilience
A second predictor of recovery speed in the infrastructure component is percentage of nonmobile homes.
Environmental Components
The lack of forests and undeveloped land in the county result in less natural protection from natural disasters and could lead to a greater amount of damage in the county after a disaster.
1st and 2nd Order Indicators
