A single definitional context was found for evacuation, which is not directly discussed as a humanitarian term or put into hierarchies. This context places evacuation within disaster risk reduction phases, as a type of emergency operation. While DRR and evacuation are interrelated, it is not clear that other organisations explicitly consider evacuation in this fashion.
In addition, it relates to all the phases of DRR including prevention, preparedness, early warning, evacuation and other emergency operation, and recovery, rehabilitation and reconstruction.
Given the lack of clear definitional contexts, the usage of evacuation in the HE corpus shows this term can be split into two significant concepts: a canonical meaning and one particular to the Israel-Palestine conflict.
Evacuation is almost always used to refer to the movement of at least one person, if not hundreds of thousands, in response to an emergency. Saving lives is the ultimate purpose of these endeavours, and humanitarians - who both manage and participate in evacuations - play several roles to improve outcomes. There are many circumstances that fall under its scope, which make up nearly the entirety of this analysis.
The team found that essential preparations were made in anticipation of the super typhoon, such that preemptive evacuations to schools, churches, stadiums, and public buildings were made.
The non-international armed conflict led to casualties, looting, further displacement and the temporary evacuation of most humanitarian workers.
The primary purpose of displacement in the form of evacuations is to save lives, but it still takes a toll on people's physical and psychological wellbeing.
In a handful of cases, evacuation is the term used to mean the relocation of Palestinian residents at the request of the Israeli government. This could be considered a type of forced evacuation, which can occur in other contexts, but it is unique as the only usage of evacuation where there is no emergency or perceived threat, and the objective of authorities is the permanent acquisition of property.
The settlement societies claim that the property was in the late 19th century a synagogue for the Yemen Jews; thus, had demanded the evacuation of the property since 2004.
Adalah represented the residents of the twin unrecognized villages of Atir-Umm elHieran before the Supreme Court to oppose the evacuation of the village, upon which, the government planned to build a Jewish town 'Hiran' and the 'Yatir' forest.
Evacuations can vary greatly in scope and intent. The list below categorises types of evacuations by characteristics that may at times overlap. By frequency, medical evacuation and its variants are by far the most common, followed by emergency evacuation and temporary evacuation.
Red Cross documents have the highest absolute and relative frequencies, and frequencies over time have remained relatively stable. Asia has the highest relative frequency among regions, although evacuation is generally common for all regions. Lastly, while Activity Reports have the highest absolute frequency, the term appears in other text types with similar, albeit lower, relative densities.

Evacuations are caused by many kinds of events and conditions, which have been loosely grouped below as generic/unspecified events, exact sources of harm, and natural hazards. Most cases of evacuation lack references to the cause of emergency, which is generally understood contextually.
None of these events/conditions have more than 35 occurrences, apart from generic causes and medical emergencies, which do not indicate the root cause of an evacuation. Nonetheless, among those listed below, tsunami, fire, flood, hurricane and earthquake have the highest frequencies.

Most people involved in evacuations are solely participants, although those who manage evacuations may take both of these roles. Generally speaking, contexts in the HE corpus refer to humanitarians and the government as the primary actors, while participants may vary greatly.

Humanitarians take a variety of roles and responsibilities before, during, and after emergencies that lead to evacuations, some of which are included in the following summary from contexts found in the corpus. Referring directly to the evacuation policies and guidebooks of organisations would offer a more detailed perspective, as Activity Reports focus on outcomes rather than exact procedures.
making preparations
building and managing evacuation centres/shelters
distributing resources (maps, radios, disaster plans)
providing disaster response training
improving preparedness
conducting evacuations
providing transport and medical care
assisting with coordination
reinforcing government operations
mediating with armed groups
continued responses
food and resource distribution
caring for especially vulnerable groups
further coordination
These exercises helped test and refine our coordinated response procedures for non-combatant evacuation operations with international partners.
The goal is to provide local residents with faster evacuation instructions by installing equipment, ocean height meters and the systems for transmitting the data from these meters, all of which apply Japanese technologies and experience.
Each involved the evacuation of hundreds of people to rest centres, where we provided psychosocial (practical and emotional) support.
We made safe spaces available to women and children, worked closely with lesbian, gay, bisexual, transgender, intersex and queer groups, and supported people with disabilities, meeting their unique needs in evacuation camps and shelters.
Child Friendly Spaces Working with other Australian emergency response agencies, we set up Child Friendly Spaces (CFS) within existing evacuation and recovery centres to ensure children have a safe place to learn and play while their parents begin the process of recovering from the disaster.
The different aspects of evacuation can be identified in contexts where the term modifies other nouns. The most common is evacuation centre, followed by evacuation plan and evacuation route, although there is considerable variation, as seen below.

Efforts to improve evacuation systems and reduce the challenge that evacuations impose fall under the related concepts of disaster risk reduction and emergency/disaster preparedness.
Income generated from greenhouses, mushroom production facilities and food processing machines has enabled the RC branches and committees to conduct disaster risk reduction activities such as establishment of early warning and evacuation system, tree planting, and construction of structures and the promotional work to improve the level of the common knowledge and expertise among the people.
Disasters have historically caused significant physical and economic losses, but the region has succeeded in reducing mortality, the result of several countries introducing disaster risk reduction measures including early warning systems and pre-emptive evacuations.
State institutions have traditionally engaged with local communities to improve disaster preparedness and devise evacuation plans.
Evacuation shares a close relationship with displacement and relocation, each of which refers to its own set of circumstances. When evacuation and displacement appear together, the latter is seen as a result of the former and is quantifiable using evacuation data.
The humanitarian community expects a new massive wave of displacement, due to ongoing evacuations of resident populations from the Lake Chad islands, as a result of military operations in the area.
The new displacement figures based on evacuation data encompass both short and long-term movements, and as such do not imply that everyone displaced by a specific hazard underwent the same experience. It is currently not possible to disaggregate the data we obtain by type and duration of movement for most of the events, yet this is key to understanding the severity of the displacement.
While some evacuees may eventually become displaced persons, the definition of displacement in the HE corpus is somewhat variable and a fuller analysis would be necessary to make clear comparisons. Notably, evacuee is a term with just over 200 cases, whereas the abbreviation IDP has nearly 14,000.
We use the term “displaced”, but it is rarely if ever adopted consistently and unequivocally by different countries or sources (see table A.9). People displaced by floods in 2015 were referred to as “homeless” in Madagascar and as “moved” in Iraq. Often, sources refer to people displaced by disasters as “directly affected”. It is true that IDPs are part of a wider population affected by a disaster, but not all those affected are IDPs. As such, additional analysis is required to make sense of the terms sources use, and to under- stand when and how they signal displacement.
"State of displacement" means the state where people are displaced, living in e.g. refugee camps with no near-term solution in sight.
The 1998 UN Guiding Principles on Internal Displacement define IDPs as: [...] persons or groups of persons who have been forced or obliged to flee or to leave their homes or places of habitual residence, in particular as a result of or in order to avoid the effects of armed conflict, situations of generalized violence, violations of human rights or natural or human-made disasters, and who have not crossed an internationally recognized State border.
In comparison, relocation has half the number of cases as evacuation and is used in a wider number of circumstances that do not necessarily originate from an emergency/disaster. Used generically, relocation can refer to moving from one location to another without implying any long-term consequences. That said, it can also be understood as a permanent change in residence after an evacuation if seen as the best/only viable option.
The necessary evacuation and relocation proved a deeply traumatic experience for many people: their social networks were disrupted and they had no possibility of returning to their homes.
Frequent words that accompany a term are known as collocates. A given term and its collocates form collocations. These can be extracted automatically based on statistics and curated manually to explore interactions with concepts.
Comparisons over time between organisation types with the greatest number of hits (RC, NGO, IGO, NGO_Fed and State organisations) may prove to be meaningful. Below is an histogram for the top yearly collocation for each of the five organisations with the greatest contribution as well as across all organisation types.
Collocational data for evacuation was found to be scarce. Across all 5 organisation types analysed, only 4 top collocates were obtained:
route;
drill;
temporary; and
medical
RC documents generated drill as top collocate for 2013.
NGO documents generated drill as top collocate in 2018 with the highest overall score. Other top NGO collocates include route and center.
IGO documents generated route as top collocate for 2007. Other top IGO collocates include centre and emergency.
NGO_Fed documents generated route in 2009 and 2018 as top collocate.
State documents generated drill as top collocate for 2009.
Organisation subcorpora present unique and shared collocations with other organisation types. Unique collocations allow to discover what a particular organisation type says about evacuation that others do not.

The chart below represents the distribution of evacuation between 2005 and 2019 in terms of the number of occurrences and relative frequency of occurrences. It also allows you to view the distribution across Regions, Organisations and Document types.
The relative frequency of a concept compares its occurrences in a specific subcorpora (i.e. Year, Region, Organisation Type, Document Type) to its total number of occurrences in the entire HE corpus. This indicates how typical a word is to a specific subcorpus and allows to draw tentative comparisons between subcorpora, e.g. Europe vs Asia or NGO vs IGO. You can read these relative frequencies as follows:
Relative frequency is expressed as a percentage, above or below the total number of occurrences, which are set at 100%. This measure is obtained by dividing the number of occurrences by the relative size of a particular subcorpus.
Under 100%: a word is less frequent in a subcorpus than in the entire corpus. This is means that the word is not typical or specific to a given subcorpus.
100%: a word is as frequent in a subcorpus as it is in the entire corpus.
Over 100%: a word is more frequent in a subcorpus than in the entire corpus. This means that the word in question is typical or specific to a given subcorpus.
As an author, you may be interested in exploring why a concept appears more or less frequently in a given subcorpus. This may be related to the concept's nature, the way humanitarians in a given year, region, organisation type or document type use the concept, or the specific documents in the corpus and subcorpora itself. To manually explore the original corpus data, you can consult each Contexts section where available or the search the corpus itself if needs be.
Occurrences of evacuation were highest in 2013, also obtaining the highest relative frequency recorded (116%).
Europe generated the greatest number of occurrences and Asia provided the highest relative frequency with 147%.
The top 5 organisation types with the highest relative frequency of evacuation are RC, C/B, State, Net and NGO.
General documents provided the greatest number of occurrences and activity reports generated the highest relative frequency with 86%.
This shows the evolution of evacuation and in the vast Google Books corpus, which gives you a general idea of the trajectory of the term in English books between 1950 and 2019. Values are expressed as a percentage of the total corpus instead of occurrences.
Please note that this is not a domain-specific corpus. However, it provides a general overview of and its evolution across domains.
Evacuation peaks in 1952 and then starts to decrease. However, it picks up in 1982 and in 2008.
Debates, controversies, and lessons learned regarding evacuations have a strong concentration in RC and European documents. 39 contexts were selected that represent a range of issues, which are roughly grouped below by the phase of evacuation they might pertain to. Also useful while discussing evacuations are success stories, which have been included further below.
While no documents in the corpus have especially high frequencies of evacuation, one relevant case study is GD-70, an HPN special issue with a focus on typhoon response that includes various aspects of evacuations.

Experience from past evacuations illustrates the importance of sustained or regular data collection over time that allows plans to be adapted to changing or unexpected circumstances.
In December 2016, the exact same tactics led to the surrender and depopulation of East Aleppo. PAX argues that what have been called 'evacuations' of civilians from both cities in the media are in fact forced population transfers. These also constitute a war crime under international humanitarian law.
The conditions at the congested evacuation centres, having limited or no access to water or soap, added to the disease risk, additionally exposing children to a range of waterborne diseases.
If the scale of the impending danger had been communicated properly, and coastal residents had been evacuated to safer ground, fewer lives would have been lost. Timeliness, clarity and coverage are essential if warning messages are to lead to sound decision-making, successful evacuation and other preparatory measures.
A plan for light rail connections between New Orleans and Baton Rouge has languished for several years. Had such a rapid transit existed, the evacuation crisis would never have occurred.
The international community is notoriously poor at providing support for preparedness and recovery and reconstruction. Investing in one component of prepared-ness – early warning systems, for instance – is fruitless without investment in other components as well, such as evacuation plans. More investment is also needed in recovery.
People with disabilities are particularly exposed at times of natural disasters and violent conflict. Cognitive, intellectual or physical impairments can reduce their capacity to access information or act on it.136 They can be left behind during evacuations or be turned away by shelters and refugee camps on the grounds that they might need complex medical care. The disaster risk reduction community needs to widen the participation of people with disabilities– and address the environmental barriers and constraints they face.
However, owing to preparedness measures, including early warnings, pre-emptive evacuations and pre-positioning of essential stocks and response personnel, it is widely believed that more lives were saved during Typhoon Bopha than during Tropical Storm Washi in the Philippines in 2011.
Evacuations were carried out effectively, and can be attributed to Indonesia's disaster management system, which includes agencies that monitor and respond to natural hazards.
Cuba and Jamaica have fully decentralized systems, comprising not only elected local councils but also officials from civil protection and other government departments. Critically, they have resources available for local-level warning and evacuation .
Japan's early warning system prevented a much larger death toll. As soon as seismic activity was detected, alerts were broadcast by television, radio and mobile phone networks. This enabled many people to prepare and mitigate the impact, such as moving to higher ground, while the country's rail network and factories quickly came to a halt–thus avoiding greater damage. Emergency sirens, clearly marked evacuation routes and public education programmes were also critical in saving lives. Strict building codes ensured that tall buildings withstood the earthquake, while forested green belts and concrete barriers provided some protection against the tsunami.
