History of Disaster Management
Disaster scholars tend to trace the development of ‘disaster management’ as a policy aim and idea back to the Lisbon Earthquake of 1775. This devastating earthquake also triggered a tsunami and several fires in the city. It occurred during and indeed fed into a time of religious and political transformation in Europe. Notably, the earthquake provoked a shift in the way many perceived disasters. In Europe, the dominant theistic view of disasters as ‘Acts of God’ was suddenly challenged by a secular, scientific view of disasters as ‘Acts of Nature’. These competing framings reflected the philosophical debates of the Enlightenment. They also enlivened the power struggle between Church and State in Europe, especially in Portugal.
Historians of disasters argue that the Lisbon earthquake prompted the new secular government of Portugal to adopt policies we now recognise as relating to disaster risk reduction and disaster management (for example,<span class="span"><span id=hint class="box-source">Russell Dynes</span><div class="popover">Source:<br><br><div>Dynes, R. The Lisbon Earthquake in 1755: The First Modern Disaster. University of Delaware, 2003.</div></div></span>). This included enforcing building regulations and developing emergency plans. But crucially, it also<span class="span"><span id=hint class="box-source">turned</span><div class="popover">Source:<br><br><div>Alexander, D. C. Natural Disasters. Routledge, 1993.</div></div></span>disaster management into a key responsibility of the (national) government. This earthquake was not an isolated catastrophe, as proved by the outbreak of plague in Marseille, France, and famine in colonial Bengal. Based on these case studies, Bandhopadhay<span class="span"><span id=hint class="box-source">argues</span><div class="popover">Source:<br><br><div>Bandhopadhay, S. All Is Well: Catastrophe and the Making of the Normal State. Oxford University Press, 2018.</div></div></span>that the rise of disaster management as a way of thinking underpinned the formation of what we now recognise as ‘nation states’. To him, today's widely adopted government structures and responsibilities are the aftermath of this series of events. In this now recognisable arrangement of disaster management, the state assumes a role of manager and protector of its citizens against the dangers posed by an external ‘Nature’. This partly explains why the term ‘natural disasters’ has traditionally been used to label these types of events. Over the past two centuries, the techniques used to achieve disaster management have developed alongside advances in technology and infrastructure. Historically, this approach to disaster management has depended on perceptions of disasters as external threats to society which, although they cannot be prevented, can be anticipated and managed to an extent that the worst impacts can be mitigated. This approach remained dominant until at least the late 20th century. It was then that critiques began to emerge.
These critiques largely revolved around the idea that disasters were not natural. Rather, they were believed to be caused primarily by social, political, and economic processes. Or, more simply, that disasters reflect and reproduce an unsustainable approach to achieving social and economic development. The logic followed that, if different decisions on achieving development were taken, the risk of disaster could be reduced. From here, the term, research topic, and policy agenda ‘Disaster Risk Reduction’ emerged.
Key ideas and terminology in Disaster Risk Reduction
It is now generally agreed amongst disaster scholars that<span class="span"><span id=hint class="box-source">disasters are not natural</span><div class="popover">Source:<br><br><div>Chmutina, K. and von Meding, J. A Dilemma of Language: “Natural Disasters” in Academic Literature. International Journal of Disaster Risk Science, 2019.</div></div></span>. However, the statement ‘disasters are not natural’ does raise an important question:<span class="span"><span id=hint class="box-source">if disasters are not natural, then what are they?</span><div class="popover">Source:<br><br><div>McGowran, P. and Donovan, A. Assemblage theory and disaster risk management.

Terminology on Disaster Risk Reduction.</div></div></span>this definition as an answer:
A serious disruption of the functioning of a community or a society at any scale due to hazardous events interacting with conditions of exposure, vulnerability and capacity, leading to one or more of the following: human, material, economic and environmental losses and impacts.
This definition is the<span class="span"><span id=hint class="box-source">outcome</span><div class="popover">Source:<br><br><div>Kelman, I. et al. Learning from the history of disaster vulnerability and resilience research and practice for climate change. Natural Hazards, 2016.</div></div></span>of several decades of academic work and research which has argued that disasters involve some kind of interaction between processes which are usually<span class="span"><span id=hint class="box-source">categorised</span><div class="popover">Source:<br><br><div>Kelman, I. Lost for Words Amongst Disaster Risk Science Vocabulary?. International Journal of Disaster Risk Science, 2018.</div></div></span>as either hazards, vulnerabilities, and capacities (sometimes called ‘resilience’). Let’s consider each of these in turn.
Climate Change and Hazards
A more in-depth overview of Climate Change is provided by the recent IPCC report on the<span class="span"><span id=hint class="box-source">physical science basis for climate change</span><div class="popover">Source:<br><br><div>Intergovernmental Panel on Climate Change. Climate Change 2021: The Physical Science Basis. 2021.</div></div></span>. ‘The climate’ is different from ‘the weather’: the changes which we all experience on a daily basis. Climate is rather the ‘average’ of various measurements of the weather over an extended period of time and in relation to a specific area. So, it is often just defined as ‘average weather’. Temperature is of central importance to almost all changes in weather. Because of this, experts use existing and predicted changes in average temperature alongside other variables to build complex understandings of how changes in average temperature might affect the frequency and intensity of certain harmful types of weather events in certain places. Such events include rainfall, snow, wind, and other processes. These analyses are thus linking changes in temperature to expected trends in the average weather in certain places. However, whilst these analyses can<span class="span"><span id=hint class="box-source">show strong correlations</span><div class="popover">Source:<br><br><div>Intergovernmental Panel on Climate Change. Climate Change 2021: The Physical Science Basis. 2021.</div></div></span>between changes in temperature and weather trends, experts<span class="span"><span id=hint class="box-source">point out</span><div class="popover">Source:<br><br><div>King, A. D. Event attribution is not ready for a major role in loss and damage. Nature Climate Change, 2023. </div></div></span>that our ability to attribute specific weather events to climate change with very high degrees of certainty remains fairly limited. This means, for example, that it is difficult to say with certainty that a specific storm, heatwave or rainfall event was caused by climate change. However, it is possible to say with varying degrees of certainty that climate change is making some types of weather events in certain places more or less likely, more or less frequent, and more or less intense. From this information, it is then possible to deduce that a given extreme or dangerous weather event was made more likely by climate change.
In scholarly work on climate change and disasters, these potentially dangerous weather events are often labelled ‘hazards’. The UNDRR<span class="span"><span id=hint class="box-source">defines</span><div class="popover">Source:<br><br><div>PreventionWeb. Terminology on Disaster Risk Reduction.</div></div></span>a hazard as:
A process, phenomenon or human activity that may cause loss of life, injury or other health impacts, property damage, social and economic disruption or environmental degradation.
UNDRR attempts to broadly categorise hazards. To do so, they use environmental, geophysical, biological, hydrometeorological, and technological criteria. A more comprehensive categorisation of hazards has recently been compiled by UNDRR in partnership with the International Science Council in their<span class="span"><span id=hint class="box-source">Hazard definition and classification review</span><div class="popover">Source:<br><br><div>United Nations Office for Disaster Risk Reduction. Hazard definition and classification review. International Science Council, 2020.</div></div></span>. A brief look at this report shows some of the complexities in categorising hazards and even determining differences between hazards and vulnerabilities. Each of these issues is linked to two recent ideas about how we should understand hazards:<span class="span"><span id=hint class="box-source">multi-hazards</span><div class="popover">Source:<br><br><div>Gill, J. C. and Malamud, B. D. Reviewing and visualizing the interactions of natural hazards. Reviews of Geophysics, 2014.</div></div></span>, and<span class="span"><span id=hint class="box-source">socionatural</span><div class="popover">Source:<br><br><div>PreventionWeb. Hazard.</div></div></span>hazards.
The idea of multi-hazards suggests that no hazard ever occurs alone, but is always part of a longer and wider causal chain of hazardous processes. The idea of socionatural hazards suggests that hazards are not always caused just by non-human, physical processes. In fact, disaster scholars<span class="span"><span id=hint class="box-source">have pointed out</span><div class="popover">Source:<br><br><div>Donovan, A. Geopower: Reflections on the critical geography of disasters. Progress in Human Geography, 2016.</div></div></span>that the potential damage a hazard might cause is shaped by social processes. Such processes span fossil fuel-driven climate change, scientific understandings of hazards,<span class="span"><span id=hint class="box-source">political decision-making</span><div class="popover">Source:<br><br><div>Donovan, A. Experts in emergencies: A framework for understanding scientific advice in crisis contexts.

The Production of an Urban Hazardscape in Pakistan: Modernity, Vulnerability, and the Range of Choice. Annals of the Association of American Geographers, 2005.</div></div></span>. All of these processes stem from human decisions. For example, flood hazards might be made more or less hazardous by the management of river systems. The use (or non-use) of dams, river straightening infrastructure, or dredging will make a difference in that regard. The<span class="span"><span id=hint class="box-source">historical context</span><div class="popover">Source:<br><br><div>Vox. The disastrous redesign of Pakistan’s rivers. 2023.</div></div></span>of the 2021 floods in the Indus Basin, Pakistan, demonstrates these ideas well. As a result of river mismanagement, new approaches have been taken to flood management in rivers and their surroundings. Indeed, the 'hard' engineering approaches to river management, such as dams, have often been found to break down over time, increasing the risk of large-scale flood events. Instead, river and flood management policy is shifting its attention to<span class="span"><span id=hint class="box-source">nature-based solutions</span><div class="popover">Source:<br><br><div>United Nations Office for Disaster Risk Reduction. Nature-based Solutions for Disaster Risk Reduction. 2021.</div></div></span>that recognise flooding not just as a hazard but as a natural river process that brings many benefits, such as irrigation, increased soil fertility, and Another good example of a hazard that is often influenced by social processes is cyclones. Cyclones can be predicted and warnings provided on that basis.<span class="span"><span id=hint class="box-source">India</span><div class="popover">Source:<br><br><div>Walch, C. Adaptive governance in the developing world: disaster risk reduction in the State of Odisha, India.

Cyclone Amphan: In Bangladesh, Preparedness Paid Off. American Red Cross, 2020.</div></div></span>have used this tool effectively to significantly reduce cyclone deaths in recent years. On the other hand, there is also<span class="span"><span id=hint class="box-source">evidence</span><div class="popover">Source:<br><br><div>Intergovernmental Panel on Climate Change. Weather and Climate Extreme Events in a Changing Climate. 2021.</div></div></span>to suggest that human-driven climate change is making more intense cyclones more frequent.
For the purposes of this overview, it is important to also point out that many hazards<span class="span"><span id=hint class="box-source">will not be affected significantly</span><div class="popover">Source:<br><br><div>Kelman, I., Gaillard, J. C. and Mercer, J. Climate Change’s Role in Disaster Risk Reduction’s Future: Beyond Vulnerability and Resilience. International Journal of Disaster Risk Science, 2015.</div></div></span>by climate change. The most obvious examples are hazards associated with the movement of tectonic plates. These notably include earthquakes and volcanoes. This fact could be taken to mean there is no need to consider climate change as a factor when developing disaster risk reduction policy for earthquakes and volcanoes. However, some contexts demand that climate change is considered in such decisions. For example, when building a dam to reduce reliance on fossil fuels in an area prone to earthquakes, climate change ought to be considered. It is also worth considering that climate change may reduce the frequency of impacts or the extent of hazards in some places. Examples might include extreme cold weather in some areas or the risk of flooding in others. A<span class="span"><span id=hint class="box-source">tool</span><div class="popover">Source:<br><br><div>Dale, B. and Stylianou, N. What will climate change look like near me?. BBC News, 2022.</div></div></span>, co-produced by the UK Met Office and the BBC, illustrates how these variations exist not only internationally, but also within countries - in this case, the UK. Acknowledging these complexities has prompted some disaster scholars to<span class="span"><span id=hint class="box-source">question</span><div class="popover">Source:<br><br><div>Donovan, A. Geopower: Reflections on the critical geography of disasters. Progress in Human Geography, 2016.</div></div></span>the importance of categorising hazards as social or natural, or as totally separate from vulnerabilities.
Vulnerabilities and the social side of disasters
The UNDRR<span class="span"><span id=hint class="box-source">defines</span><div class="popover">Source:<br><br><div>PreventionWeb. Terminology on Disaster Risk Reduction.</div></div></span>vulnerabilities as:
The conditions determined by physical, social, economic and environmental factors or processes which increase the susceptibility of an individual, a community, assets or systems to the impacts of hazards.
The idea of vulnerability in disasters directs attention to how physical, social, political, economic, and cultural processes put people in harm’s way. Being vulnerable, in that sense, would mean having a higher probability of being harmed by a potential disaster due to these processes. The development of theories of vulnerability is also largely responsible for the shift in thinking about the ‘naturalness’ of disasters. One of the most influential theories was the book<span class="span"><span id=hint class="box-source">At Risk II: Natural Hazards, People’s Vulnerability and Disaster</span><div class="popover">Source:<br><br><div>Blaikie, P. et al. At Risk: Natural Hazards, People's Vulnerability and Disasters. Routledge, 2004.</div></div></span>, first published in 1994. The most well-known part of the book is the Pressure and Release Model, which tries to illustrate how disasters happen. Its overall argument is that if vulnerability is the ‘root cause’ of disasters, reducing vulnerability should be the main goal of ‘Disaster Risk Reduction’.
The 1976 earthquake in Guatemala, studied in At Risk II, and a whole host of other cases, showed a strong correlation between disaster impacts and socioeconomic class. This research feeds into left-wing, Marxist-inspired conceptual frameworks. It<span class="span"><span id=hint class="box-source">found</span><div class="popover">Source:<br><br><div>Pelling, M. The Vulnerability of Cities: Natural Disasters and Social Resilience. Routledge, 2003.</div></div></span>that poorer people are often more exposed to the impacts of hazards and usually less able to deal with the long-term impacts than those of a higher socioeconomic class. All in all, this theory describes reality as follows: the poorer you are, the more vulnerable you are to potential disasters.
This theory has reinforced the assumption that poorer and marginalised people are often forced to live in places which are more exposed to the impacts of hazards because they cannot afford to live elsewhere. This might be along a river prone to flooding or on a steep slope prone to landslides. An extreme but clear example of these drivers of vulnerability would be Rohingya refugees<span class="span"><span id=hint class="box-source">living in overcrowded camps</span><div class="popover">Source:<br><br><div>Zaman, S. et al. Disaster risk reduction in conflict contexts: Lessons learned from the lived experiences of Rohingya refugees in Cox's Bazar, Bangladesh. International Journal of Disaster Risk Reduction, 2020.</div></div></span>which are exposed to cyclones, floods, and landslides as well as a host of health and sanitation issues. Beyond the role of socially and politically constructed poverty,<span class="span"><span id=hint class="box-source">research</span><div class="popover">Source:<br><br><div>International Federation of Red Cross and Red Crescent Societies. World Disasters Report 2014.</div></div></span>has also suggested that people might choose to live in such places on purpose. Indeed, these poor populations may have determined that the benefits of doing so outweigh the potential risk of disaster. They may have economic and cultural advantages in settling in such<span class="span"><span id=hint class="box-source">areas</span><div class="popover">Source:<br><br><div>International Federation of Red Cross and Red Crescent Societies. World Disasters Report 2014.</div></div></span>. Scholars of gender and disasters would also point out that the experience of vulnerability is not the same for men, women, and other gender identities. The same issue of different experiences of<span class="span"><span id=hint class="box-source">social vulnerability to natural hazards</span><div class="popover">Source:<br><br><div>Cutter, S. L., Boruff, B. J. and Shirley, W. L. Social vulnerability to environmental hazards. Hazards vulnerability and environmental justice. Routledge, 2012.</div></div></span>can be made for<span class="span"><span id=hint class="box-source">other groups who are marginalised</span><div class="popover">Source:<br><br><div>Thomas, D. S. K. et al. Social Vulnerability to Disasters. Routledge, 2013.</div></div></span>for non-economic reasons. Skin colour, religious belief, age, ability, and other variables can affect their vulnerability. Because of these complexities, most scholars<span class="span"><span id=hint class="box-source">agree</span><div class="popover">Source:<br><br><div>Bankoff, G. and Hilhorst, D. Why Vulnerability Still Matters: The Politics of Disaster Risk Creation. Routledge, 2022.</div></div></span>that although vulnerability is often closely tied to socioeconomic class, it is also always tied to context, culture, and other shifting social relations.
Despite its importance to the field, some scholars are<span class="span"><span id=hint class="box-source">critical of the idea of vulnerability</span><div class="popover">Source:<br><br><div>Bankoff, G. and Hilhorst, D. Why Vulnerability Still Matters: The Politics of Disaster Risk Creation. Routledge, 2022.</div></div></span>. Many have argued that a focus on vulnerability is too negative and tends to frame disaster victims as inferior or helpless. For scholar Greg Bankoff, such a framing even<span class="span"><span id=hint class="box-source">reflects a colonial worldview</span><div class="popover">Source:<br><br><div>Bankoff, G. Rendering the World Unsafe: ‘Vulnerability’ as Western Discourse. Disasters, 2022.</div></div></span>. As a result, it has been argued that it is very important to think about people’s capacities to deal with the processes that make them vulnerable, and to understand and deal with hazards. Such a shift in perception would mean that exposed populations would no longer be passive victims. Instead, they would actively prepare for and respond to crises.
Capacities and resilience
The UNDRR<span class="span"><span id=hint class="box-source">defines</span><div class="popover">Source:<br><br><div>PreventionWeb. Terminology on Disaster Risk Reduction.</div></div></span>capacity as:
The combination of all the strengths, attributes and resources available within an organization, community or society to manage and reduce disaster risks and strengthen resilience.
The development of theories of capacities, as they relate to disasters, emerged to provide a more optimistic view of the ‘social’ aspects of disasters. Some scholars<span class="span"><span id=hint class="box-source">argue</span><div class="popover">Source:<br><br><div>Manyena, S. B. The concept of resilience revisited. Disasters, 2006.</div></div></span>it is essential to not only focus on how people are put at risk by processes beyond their control, but rather to think about how they might work against these forces to reduce the risks they face. This is important not only because it corrects the view that people vulnerable to the impacts of disasters are helpless or without agency. It also matters because such a focus can inform proactive policy and practices. The end result would then be<span class="span"><span id=hint class="box-source">more ways</span><div class="popover">Source:<br><br><div>Twigg, J. Characteristics of a Disaster-resilient Community. Department for International Development, 2007.</div></div></span>to ‘build’ capacity and resilience and ‘reduce’ vulnerability.
Governments, communities, and individuals all hold the capacity to prevent the possibility of disaster. For example, they can create and enforce building regulations to prevent building collapse during earthquakes. They may also work on clearing drains in advance of the monsoon season to reduce flood and landslide risk. However, scholars have consistently<span class="span"><span id=hint class="box-source">pointed out</span><div class="popover">Source:<br><br><div>Klein, R. J. T., Nicholls, R. J. and Thomalla, F. Resilience to natural hazards: How useful is this concept?. Environmental Hazards, 2003.</div></div></span>that thinking of capacity as the inverse of vulnerability is an oversimplification. In the real world, people usually have the capacity and resilience to deal with disasters. This is the case even though they live in conditions of vulnerability due to processes beyond their control. Gemma Sou’s recent work on the impacts of Hurricane Maria on Puerto Rico is a useful demonstration of this idea - visualised in a<span class="span"><span id=hint class="box-source">graphic novel</span><div class="popover">Source:<br><br><div>Humanitarian and Conflict Response Institute. After Maria: Everyday Recovery From Disaster. University of Manchester, 2019.</div></div></span>. Sou<span class="span"><span id=hint class="box-source">reframes resilience</span><div class="popover">Source:<br><br><div>Sou, G. Reframing resilience as resistance: Situating disaster recovery within colonialism. The Geographical Journal, 2021.</div></div></span>not just as the ability to deal with the impacts of the disaster, but also to resist and deal with other forces, i.e. the neo-colonial attitude of the United States towards Puerto Rico. This nuance is important. It reinforces the idea that people affected by disasters are not inherently ‘vulnerable’ but rather creative, strong, and cooperative. This re-framing of resilience directs attention to the political, economic, and cultural processes that have and continue to marginalise them before, during, and after disastrous events and processes. Overall, it is vital to consider both capacities and vulnerabilities as<span class="span"><span id=hint class="box-source">distinct but interconnected issues</span><div class="popover">Source:<br><br><div>Weichselgartner, J. and Kelman, I.
