Building Resilience with Decision Analysis

By Jeffrey Keisler, on 25 May 2023

I have the wonderful honour of being a MAPS Fellow at UCL. This came about through conversations with my friend and colleague (and now host), Prof. Gianluca Pescaroli. Although we bonded through discussions about used vinyl records, I will instead talk about our work.

My background is in decision analysis, a field that takes quantitative approaches involving probability, utility, and decision trees to identify the overall risks and benefits associated with actions under uncertainty. In the context of resilience, there is much uncertainty but most of the focus is on trying to improve systems.

Thinking of information as a separate dimension of protection–because information helps people make the decisions that lead to optimal recovery–can lead to lower cost ways to bring about greater resilience. But improving information itself is costly. It can be tricky to figure out which information-related efforts are worthwhile. There are different ways to bring information into a decision process.

By taking a concept from decision analysis, value of information (VOI), we can take a more strategic approach. We can actually quantify the benefit of different possible efforts. Basically, we characterise the mix of potential consequences of making the best possible choice given a limited amount of information and compare this with what would happen if the same decisions were made with the benefit of more information. With this analysis, we can improve resilience by making investments to ensure that relevant information will be available after disruptions. These can be just as beneficial as investments in physical assets which can also minimise the damage of disruptions.

In managing resilience, we anticipate possible disruptions, and consider what can happen before, during, and after them. With a VOI approach, we also consider what information will be available for which decisions before, during, and after disruptions, and then can take steps to make that information available during those periods. Examples include purchasing information, building better information systems and communication systems, performing experiments, or potentially buying time for information to arrive by speeding decisions implementation and freezing damage during the time we’re waiting for information.

During my time at UCL I am meeting with a number of researchers in IRDR to apply this idea efficiently to problems in several important areas where we are studying resilience. These include healthcare, natural hazards, and technological or business crises. With these results, we can look toward building more sophisticated analyses or refining the planning process to flesh out the informational dimension. The researchers here have backgrounds in quantitative areas such as risk analysis and systems analysis as well as in the social sciences and in the physical sciences. There are many different types of data and phenomena to consider as we pull together these models. My hope is this will lay the groundwork for future valuable projects and continued collaboration.

Insights on Addressing Vaccine Hesitancy: Reflections from the 16th Vaccine Congress

By Lan Li, on 14 March 2023

The COVID-19 pandemic has posed major challenges to public health systems across the world. Meanwhile, vaccination has been developed and delivered at record speed, while its application has been limited by vaccine hesitancy, which refers to “a delay in acceptance or refusal of vaccination despite the availability of vaccination services”, defined by the World Health Organization (WHO) strategic advisory group of experts (WHO SAGE). This can be due to various reasons at various levels, such as misinformation, lack of trust in the healthcare system, or personal beliefs and values. It is a complex problem, resulting in challenges in understanding and designing targeted interventions to solve it.

A venue for all

The 16th Vaccine Congress held in Italy aimed to address vaccine-related issues and to build health system resilience by discussing the latest advancements in vaccine research, development and implementation. The congress brought together leading experts from the fields of vaccinology, public health, medicine, epidemiology, and social sciences, who discussed the challenges posed by vaccine development, vaccine delivery and vaccine hesitancy and ways to overcome them. 

As one of the early career researchers in vaccine hesitancy, it is a great opportunity for me to discuss this issue with researchers from other backgrounds and understand the hesitancy problem through a broader lens. During the conference, our discussions centred around the importance of promoting accurate information about vaccines, improving communication between healthcare providers and the public, and increasing public trust in the healthcare system. In addition, we also discussed whether vaccination is actually safe and what kind of vaccination is safer. Admittedly, these questions were hard to answer and the only reliable evidence is the data from RCTs (in short term). However, it opens a new way for understanding the vaccine hesitancy problem – the vaccine itself has created the ideal conditions for mistrust to thrive, due to its complexity and variability of development and evaluation. To solve this problem, more collaboration is needed between experts from vaccine R&D, health education, behaviour science and more.

Introducing my research to other peers

The role of social media

One of the most-impressed presentations was “addressing vaccine hesitancy:  integrating the Vaccine Trust Gauge and effective communication to advance confidence and uptake”, given by Prof Scott Ratzan, from CUNY School of Public Health and Health Policy. His speech highlighted the role of media in shaping public perception of vaccines and emphasized the need for health organizations to engage with the public and correct misinformation about vaccines on mass media and social media. In particular, social media platforms have become a major source of information for many people, and the spread of false information about vaccines on these platforms can lead to confusion and fear. In turn, this can lead to lower vaccine uptake and increase the risk of outbreaks of vaccine-preventable diseases.

However, the role of social media in shaping public perception of vaccines is crucial, and it is essential for health organizations to engage with the public on these platforms. Health organizations can use social media to correct misinformation about vaccines, provide accurate information, and address the concerns of the public, which is the way to build public trust and increase vaccine uptake. It can also be used to promote positive stories and experiences of people who have been vaccinated. By using social media in a proactive and strategic way, health organizations can counter the spread of misinformation about vaccines and help to increase public understanding of the importance of vaccination.

Slide summarizing our challenges for building vaccine trust, presented by Prof Scott Ratzan

Admittedly, it is also important to note that social media can also be used to spread false information and to promote anti-vaccine messages. Health organizations must be vigilant in monitoring social media and must take action to counter false information and misinformation. They can do this by partnering with trusted sources, such as public health organizations and scientific institutions, to provide accurate information about vaccines.

Challenges at community-level

Another key area of discussion was the importance of involving communities in the decision-making process about vaccines. In the second day of the conference, a roundtable discussion was held to make the statement on multisectoral actions for building trust to promote vaccine acceptance. I was fortunately involved in the discussion and shared my opinions. The discussion emphasized the need for health organizations to listen to the concerns of the public, provide clear and concise information about vaccines, and involve communities in the planning and implementation of vaccine programs. The challenges for addressing vaccine hesitancy at the community level includes:

  1. Misinformation and distrust: The spread of misinformation and false information about vaccines can lead to confusion and distrust among the public. This can be particularly challenging for health organizations, as people are often exposed to a large amount of information from a variety of sources, including social media, friends, and family.
  2. Personal beliefs and values: individuals may have personal beliefs or values that conflict with getting vaccinated. For example, they may believe that vaccines are unnatural or harmful, or that they are not necessary.
  3. Lack of access to accurate information: communities may not have access to accurate information about vaccines, or may not understand the benefits of vaccination. This can lead to misunderstandings and reluctance to get vaccinated.
  4. Healthcare provider distrust: individuals may not trust healthcare providers or the healthcare system, which can make them reluctant to get vaccinated.
  5. Barriers to accessing vaccines: communities may face barriers to accessing vaccines, such as poverty, lack of transportation, or limited access to healthcare.
  6. Resistance to change: individuals may resist getting vaccinated because they have always lived a certain way and are resistant to changing their habits or beliefs.

To address these challenges, several discussions were made between experts from different background, including researcher, healthcare workers, vaccine company staff, community workers and the public. They provided many insightful strategies to solve this problem.  A statement paper proposed the framework for engaging multiple sectors for building vaccine trust was under preparation and will be published following the conference.

The congress also discussed the importance of providing equitable access to vaccines, particularly for marginalized communities. The speakers emphasized the need to address the root causes of vaccine hesitancy, such as poverty, lack of education, and poor access to healthcare, in order to ensure that everyone has access to vaccines.

Strengthen health system resilience

The congress also highlighted the importance of building a strong health system in order to improve vaccine uptake. The speakers discussed the need for investment in health systems to increase access to vaccines, improve the quality of care, and ensure that health systems are prepared to respond to the next public health crisis. It provided a new way for me to reconsider the role of my research in the health system and DRR.

Firstly, vaccine hesitancy can have a significant impact on the health system, both in terms of public health outcomes and healthcare costs. When individuals are reluctant or refuse to get vaccinated, it can lead to outbreaks of vaccine-preventable diseases, which can put vulnerable populations, such as the elderly, young children, and individuals with weakened immune systems, at risk. Outbreaks of vaccine-preventable diseases can also put a strain on the healthcare system, as more resources are needed to diagnose and treat cases and to control the spread of the disease. Secondly, vaccine hesitancy can lead to increased healthcare costs, as individuals who are not vaccinated are more likely to require medical care, including hospitalization, for vaccine-preventable diseases. This can put a strain on healthcare budgets, particularly in resource-limited settings, and can divert resources away from other important healthcare needs. In addition to the impact on public health and healthcare costs, vaccine hesitancy can also undermine efforts to achieve herd immunity, which is critical for controlling the spread of vaccine-preventable diseases. 

Overall, attending the 16th Vaccine Congress was a valuable and enriching experience for me as a PhD student. It provided a valuable opportunity to deepen my understanding of the current challenges and strategies for addressing vaccine hesitancy. During the conference, I had the opportunity to listen to leading experts in the field, and to engage in discussions with other researchers, healthcare professionals, and policymakers. This helped me to gain a comprehensive understanding of the current state of knowledge on vaccine hesitancy, and to identify areas for future research and inquiry, and enhance my own PhD project. I am grateful for the opportunity to attend this important event, and I look forward to continuing to engage with others in the field to advance our understanding of this important issue.

Learning from Fire and Rescue services in London and Bergen

By Joshua Anthony, on 17 February 2023

Author: Jarle Eid


Researchers from University College London, Haukeland University Hospital, National Defense University in Sweden and the University of Bergen met in January for a working meeting on a joint research project focusing on how operational psychology can inform municipality responses and resilience to disruptive events.

What kind of operational situations are seen as most challenging and difficult to handle for fire and rescue workers? How did the COVID-19 pandemic influence operational capacity and resilience in the Fire and Rescue Services? What future training and educational needs are seen as most important to develop resilient fire and rescue services? What can we learn from cross national comparisons of fire and rescue services in London and in Bergen?

These and other questions are being explored based on in depth interviews with first responders in a cross-country comparison of Fire and Rescue services in Bergen and in London. The study is supported by a grant from the Regional Research Fund in Western Norway, the Fire and Rescue services in Bergen, and the Greater London Authorities.

We are very pleased to have this opportunity to collaborate with Professor Ilan Kelman and Associate Professor Gianluca Pescaroli on this new project. Here we are exploring three main issues. One is how the fire end rescue services were affected by the protracted covid situation, secondly we explore and collect examples of difficult operational situation, and thirdly, we explore training and development areas.

A particularly exciting issue is that in this project we have been collecting data both from Norway and from the U.K. and a cross national comparisons will be a true advantage to this project. In January we had the first joint working group meeting in Bergen, Norway and in April we will have the second working group meeting in London with our UCL colleagues.

Reflections on the Turkish-Syrian Earthquakes of 6th February 2023: Building Collapse and its Consequences

By David Alexander, on 9 February 2023

An interesting map was published by the US Geological Survey shortly after the Turkish-Syrian earthquakes.1 It showed (perhaps somewhat predictively) that there was only one tiny square of the vast affected area in which Modified Mercalli intensity (which is largely a measure of damage) reached 9.0, the ‘violent’ level.2 This is–just about–enough to damage very significantly a well-engineered structure (but not necessarily enough to bring it crashing down). Although the disaster of 6th February 2023 produced, in fact, stronger shaking than this, it should not have caused 5,500 large buildings to collapse. The disaster in Turkey and Syria is very obviously the result of poor construction. This is painfully visible in the video images of buildings collapsing. The patterns of collapse are also the same as those in the last 20 Turkish earthquakes, although they are doubtless more extensive this time around. 

Building codes in Turkey have been upgraded five times in the last 55 years and are now perfectly good enough. The tragedy lies in their non-observance and the paucity of retrofitting. It is a mixture of simple errors, lax procedures, ignorance, deliberate evasion, indifference to public safety, untenable architectural fashions, corruption and failure to enforce the codes. Many, perhaps most, people in Turkey live in multi-storey, multiple occupancy reinforced concrete frame buildings. It is these that collapse. Most of them are highly vulnerable to seismic forces. There is plenty of engineering literature on the typical seismic performance defects of such buildings in Turkey. Perhaps we can grant a small exception for Syria, although before the civil war it did have building codes and earthquake research. However, the comment by a leader of the Syrian Catholic Church that buildings had been weakened by bombardment was something of a red herring. This probably affected about 2-3% of those that collapsed. 

 To know whether a reinforced concrete building is safe to live in would require knowledge of:

  • the shear resistance (i.e., quality) of the concrete 
  • the presence or absence and connectivity of shear walls 
  • whether there are overhangs or other irregularities of plan that distribute the weight of the building unevenly or concentrate load on particular parts of it 
  • the presence or absence of a ‘soft-storey’ open ground floor which concentrates the load above columns that cannot support it during seismic deformation 
  • the connections between beams and columns, especially how the steel reinforcing bars are bent in 
  • whether there are proper hooks at the end of rebars on concrete joints 
  • whether the rebars were ribbed or smooth 
  • the quality of the foundations and the liquefaction, landslide or subsidence potential of the underlying ground 
  • the state of maintenance of the structural elements of the building 
  • any subsequent modifications to the original construction. 

 An experienced civil engineer could evaluate some of that by eye, but much of the rest is hidden and only exposed once the building collapses. A short bibliography of sources is appended at the end of this article. 

Many of the news media that have reported the disaster have presented it as the result of inescapable terrestrial forces. While that cannot be negated, it is less than half of the story. The tragedy was largely the result of highly preventable construction errors. Vox clamantis in deserto: to examine this aspect of the disaster one would have to face up to difficult issues, such as corruption, political decision making, people’s expectations of public safety, fatalism versus activism, and more. How much simpler to attribute it all to anonymous forces within the ground! 

A well-engineered tall building that collapses will leave up to 15% void spaces in which there may be living trapped victims. It was notable that, in many buildings that pancaked in Turkey and Syria, the collapses left almost no voids at all, thanks to the complete fragmentation of the entire structure. This poses some serious challenges to search and rescue. In some cases the collapse was compounded by foundation failure, leading to sliding or rotation of the debris. 

There was also an interesting dichotomy in the images on television between the “anthill” type of urban search and rescue, carried out by people with no training, no equipment and no idea what to do, and professional urban search and rescue (USAR), which sadly was in the minority of cases. Nevertheless, it remains true that the influx of foreign USAR teams is, sadly, both riotously expensive and highly inefficient, as they tend to arrive after the ‘golden period’ of about 12 hours in which people could be rescued in significant numbers. 

Among the damage there is at least one classic example of the fall of a mosque and its minaret, the same as that which happened in the Düzce earthquake of 1999. Mosques are inherently susceptible to collapse in earthquakes: shallow arches, barrel vaults, rigid domes and slender minarets. The irony is that the great Turkish architect of the 16th century, Mimar Sinan (after whom a university in Istanbul is named) had the problem solved. He threaded iron bars through the well-cut stones of his minarets, endowing them with strength and flexibility. It is also singular that one of the first short, stubby minarets in Turkey (located in Izmir) was built 300 years after Sinan died in 1588.

The Search for a Natural River

By Joshua Anthony, on 27 January 2023

Following the UK’s exit from the European Union, the legacy leftover from the EU’s Water Framework and Flood Directives, which jointly encourage sustainable management of flood risk, lives on. The UK has seen a number of similar national policy frameworks implemented aiming to reduce flood risk while improving water quality and biodiversity, with over 100 river restoration projects seen in London alone between 2000 and 2019. Most of these efforts are geared towards sustainability in the face of climate change, but, with regards to the long-term, the river itself is often left out of the plans.

The historic human efforts to manage rivers have been progressively called into question over their sustained maintenance costs and an incongruity with environmental and ecological health. An alternative solution is to renaturalise and restore natural processes—reconnecting rivers with their floodplains, reintroducing wild species, run-off targeted tree planting—but this would also be to submit to a changing and dynamic landscape. Rivers can change course—sometimes very suddenly—or silt-up and become unnavigable. True sustainability should therefore account for the long term changes of rivers, but these changes are rarely accounted for in flood risk management policy. As Andrew Revkin asks: “sustain what?”

The problem with “natural”

The problem is partially semantical. The terms renaturalisation, restoration, and rewilding carry with them the image of an implied prior state or a “Lost Paradise”. Ironically, it is precisely the long legacy of human engineering, which some modern schemes are trying to reverse, that denies us the knowledge of a natural state; it is difficult to look into the past, when the waters are so muddied by our imprint. As a result, our ability to assess the future impact of renaturalisation is equally hindered. 

Arguably nowhere in the UK is this problem illustrated better than in the Somerset Levels, which as far back as the roman occupation of Britain has seen artificial drainage and reclamation in order to take advantage of its pastoral and arable potential. At present, the flat, largely reclaimed floodplain relies heavily on a vast network of excavated drainage ditches (rhynes in the local vernacular), sluice gates (clyces), and pumping stations that push the water through the highly banked and augmented river channels; a £100 million tidal barrier has just been approved on the River Parrett, while existing rivers continue to be enlarged to carry extra flood water. Clearly, it is hard to imagine what natural means in this context.

A clyce (sluice gate) in Highbridge that stops in the inflow of tidal water.

Seeing Into the Past

Fortunately, remnants of abandoned rivers—palaeochannels—that have long since stopped flowing through the Levels litter its landscape and offer a glimpse into the past. There are numerous examples of such ancient rivers still visible on the Somerset landscape today, which often surface during high flood stages, but are now easily identifiable with the advent of Light Detection and Ranging (LiDAR) technology, which provides high-resolution elevation data. Palaeochannels have been of interest to researchers in this area because they reveal historic drainage patterns, showing in which direction rivers used to flow before being redirected or abandoned long ago.

Where archaeological records are unavailable—often early in or before human occupation—the reasons for change are less clear. Were the causes human made, or related to a historical climatic shift? And could this inform the way we plan rivers today? To find out more, it is necessary to dig deeper into the landscape. 

The Somerset Levels have experienced their own fair share of devastating floods and are intensely embroiled in the debate between hard engineering measures and natural flood management, which has previously culminated in fierce criticism of the Environment Agency for not carrying out regular dredging. This image reveals an ancient river channel emerging from the flood waters of 2013/2014 around Burrowbridge, Somerset.

Seeing Beneath the Surface

Beneath the sediment that buries them are rivers preserved from a past time. Within the sediment is contained information from the processes and conditions that presided over the river’s eventual abandonment. Here we can see the geometry of the river and look for signs of erosion and migration, and indicators for the causes of abandonment.

A seismic refraction survey conducted in the Somerset Levels.

To overcome the logical problem of seeing buried features, geophysical methods offer a quick and non-invasive way of imaging the subsurface. By applying a force to the ground and measuring a response from beneath, a model of the rivers can be produced. These methods have been tested extensively by scientists for many years in a variety of environments, including floodplain sediments, and are in the UK probably most famously associated with Time Team’s “geofizz”, due to their strong archaeological applications. 

This research uses a combination of electrical resistivity, seismic refraction, and ground penetrating radar methods to image the buried cross-section of ancient rivers. In this way, the river acts as an archaeological feature for investigating the past, and is hoped to provide reference states for river systems that have existed prior to and throughout different periods of human occupation. Surveys have been completed on two sites on either side of the River Parrett, clearly showing the extent of the historical river systems. More are to follow at different sites across the Somerset Levels.

Glimpsing into the past of ancient river systems could help in planning for the future development of renaturalised rivers, by exploring scenarios where the measures that humans (and rivers) have grown accustomed to are absent. It may be that, like a river, management plans must be dynamic and adaptable to natural change; otherwise, a one-size-fits-all approach to sustainability is bound to become unsustainable.

Vulnerability is the root cause of Pakistan’s susceptibility to disasters

By Joshua Anthony, on 21 November 2022

Author: Dr. Laila Shahzad*


According to the IPCC AR5, the human influence on the planetary climate system is undeniable and emissions from greenhouse gases (GHGs) are at the highest levels ever seen in the history of mankind. These climatic changes have had widespread impacts on human and natural systems. The most visible effects of changing climate are variation in rainfall pattern, increasing average temperature, glacier melting, rising sea levels, crop diseases, species invasions, weather related disasters and many more. Human activities involved in bringing these changes are industrial processes, fossil fuel burning, vehicular emission, and agriculture. The unpredictable rainfall patterns and variable seasonal precipitation badly influence the soil water availability for crop, loss from floods or drought, and become a serious issue for the farmers of South Asia and policy makers as a greater threat to food security.

South Asia, a region chiefly described as having agricultural-based economies, is considered as the most vulnerable region in the world. As the change in food growth and production will directly affect the food needs of burgeoning population due to disturbance in financial, ecological, and social systems on this part of planet earth. The situation in the region is worsened by locality, topography, socio-political influences, literacy rate, unskilled labourers, economic instability, poverty, and livelihood dependency on natural resources.

Pakistan, a country with 225 million (approx.) inhabitants suffered by the unprecedented floods in June 2022 which lasted for months. Torrential monsoon rains triggered the severe flooding which washed away thousands of houses and crop land leaving people homeless and food insecure.

A little background

Pakistan is the second largest country by its area in South Asia after India, and is highly vulnerable to climatic changes, ranked among the top ten countries by the Global climate risk index of the world in past many years. The country is recurrently affected by the disasters in both the long term index and in the index of a respective year, alluding to the persistent nature of underlying vulnerabilities. The climate of the country ranges from subtropical arid to semi-arid and temperate to alpine. Precipitation varies from 100 to 2000 mm mainly from June to September across the countryside. It is broadly an agrarian country with a contribution of 21% to GDP from agriculture which provides employment to 62% of the population. The main crops are wheat, cotton, and rice grown at different agro-ecological zones of the country with diversified hydrological, soil, and climatic conditions. Temperature and rainfall show constantly increasing and decreasing trends, respectively. Since the start of the 20th century, the rising temperature has caused an increase in demand of evapotranspiration for crops by up to 10-30%. The agricultural system in Pakistan is already worsened by the urbanisation as it has decreased the production due to conversion of fertile land into housing societies. On the other side, recurring floods end up losing the soil fertility and disturbing the crop cycle.

Floods of 2022: a compound disaster

The 2022 Pakistan floods caused unprecedented damage to agriculture crops, livestock, and infrastructure, including damages to storage facilities with tons of grain, posing unmeasurable risk. Badly affected crops include—but are not limited to—rice, sugarcane, cotton, wheat, and small-scale farmers totally lost their livelihood. Pakistan is the world’s fifth-largest producer of cotton and produces about 5% of world’s demand which will affect the supply due to flood damages.

According to the World Bank, the worst hit sectors are housing, agriculture, livestock, and, lately, transport and communications with significant damages of USD 5.6 billion, USD 3.7 billion, and USD 3.3 billion, respectively (Pakistan Floods 2022 Post-Disaster Needs Assessment). This actually calls for cascading effects as such massive disasters have tangible and intangible losses; in terms of water borne diseases, shortage of food, price hike, loss of machinery, post disaster trauma, losing mental health and wellbeing, and disturbing the crop cycle due to water logging.

So now the question arises: could this event be controlled or at least better managed? What Strategies did Pakistan have to minimise flood losses? The government of Pakistan is currently in the phase of recovery, where bringing people back to normal life is not easy. Though time has proved that this tragic event has to be a turning point when it comes to making disaster risk reduction policy for the vulnerable. The policy should have focused on the most vulnerable in enhancing climate resilience and adaptations by developing community-based disaster management at district and tehsil levels. Focus should be on nonstructural risk reduction measures by giving disaster education to the masses. In the shortest way, the emergency health system, training local farmers, introducing livelihood diversification, and emergency cash transfer system can be prioritized. This calls for interactive and integrated polices where communities need to be prepared for future disasters and be a part of policy making. The government tiers have to be more connected than working in isolation as managing the compound impacts will not be an easy job.

With the theme of building back better, Pakistan should not only manage the losses and provide immediate support to families; rather, a long way to go is “to plan” as climatic emergencies will keep coming with more magnitude and frequency, and to the more vulnerable.

Pushing the Boundaries in Disaster Studies: Reflections from the NEEDS 2022 PhD Workshop

By Mhari Gordon, on 14 November 2022

Mhari Gordon is a PhD student at UCL-IRDR.

This blog was jointly posted with RADIX and COPE.


This month, November 2022, I was fortunate enough to attend and present at the Northern European Emergency and Disaster Studies (NEEDS) Conference as well as participate in the preceding PhD workshop. The PhD workshop was run over a day and a half by Emmanuel Raju, Ksenia Chmutina, and JC Gaillard and attended by 18 PhD students. The workshop was a fantastic experience and great opportunity to meet enthusiastic disaster scholars.

NEEDS PhD Workshop participants, facilitators, and guests. Photo credit: Ksenia Chmutina (original photo link).

The workshop kicked off with an activity mapping how our PhD research topics connected in terms of key concepts, methodologies, research subjects or objects, and geographical locations. Despite diversity in our research orientations and backgrounds, the mapping exercise highlighted overlaps. For example, many of our studies focus on groups which are under-represented individuals in disaster studies, such as genders beyond the binary, learning challenges, youth, and refugees. We also noticed a trend in using methodologies which sit more on the mixed and qualitative methods side, moving away from large-scale approaches observed in quantitative methods.

Moreover, we recognised and spoke about our experiences of using concepts such as vulnerability, resilience, and intersectionality. Terms which were originally critical ‘western’ concepts that have now turned into mainstream buzzwords and act as blanket and uniform (or universalism) approaches in disaster studies. There is a tension between reclaiming the true heterogeneous nature of such concepts, but also debating the need to move beyond them. Such concepts may not have the same meanings, or even exist, in all cultures and languages. New disaster studies need to be more reflective and critical by expanding out of the previous siloing and labelling as well as welcoming the diversity of cultural contexts. This led to us reflecting on our positionality in studying disasters and how to navigate this in terms of methodologies and sharing our messages with audiences. During the afternoon sessions, we started asking questions such as why is the research being done and who will benefit? We then analysed and critiqued a more extensive set of questions which is outlined in the RADIX Disaster Studies Accord (link).

The second morning was dedicated to publishing in disaster journals. The workshop facilitators and guests, including Christine Eriksen, Rodrigo Mena, Eefje Hendriks, and Ricardo Fuentealba, shared valuable and practical advice. The two key takeaways from the morning were to consider 1) the editors of a journal and 2) the format of publication. As authors of academic publications, we need to critically consider how we can best present and do justice to the messages that we are sharing. This may be in the likes of keeping parts of the text in the original language so that the local context and meaning are not lost in translation or interpreted with western-academic terms and norms. Or the likes of different formats to the standard academic paper such as a comic strip – which will be included in an upcoming issue of the Disaster Prevention and Management Journal (journal link).

The advice shared with the PhD students for publishing in Disaster journals was:

Ask colleagues and mentors about their experiences with different journals and seek their advice on which journal they think is most suitable for our manuscript.

Read the scope of the journal and if there is still uncertainty about whether our manuscript’s topic fits, then send an email to the editor(s) asking for their advice before formally submitting.

Look at which journals our citations and references, as well as scholars with similar research interests, have published in. This will give one an initial indication of the type of work which is accepted by the journal.

Editors can usually tell by the title and first few sentences of the manuscript whether it will be accepted for peer review or not – so our manuscript needs to be convincing from the start.

Do not panic if it is taking a few months between the manuscript being accepted for review and receiving feedback. It can take time to find appropriate and willing reviewers and for them to review the manuscript. There are also unexpected delays or interruptions during this process.

Finally, if the authenticity of the research and manuscript does not match the standardised format but fits within the scope of a journal, then we should not hesitate to contact the editor(s) to see if they are willing and able to find a creative solution!

Overall, the key message from the PhD workshop was to keep pushing the boundaries of disaster studies, in terms of concepts, methodologies, and assumptions, as well as how we share our research!

Building Resilience of Women for Food Security  

By Joshua Anthony, on 26 October 2022

Written by Bhawana Upadhyay


A growing body of literature suggests that climate disasters such as heatwaves and flash floods disproportionately affect the most vulnerable inhabitants of rural communities.  An analysis of 130 peer-reviewed studies published in Nature Communications suggests that women and children often face disproportionately higher health risks posed by climate change impacts than others.  For example, pregnant women often experience more risks and limited access to reproductive and maternal care services during and post disasters.

UNICEF reported that due to the recent flooding in Pakistan, about 3.4 million children needed urgent humanitarian assistance and faced an increased risk of waterborne diseases, drowning, and malnutrition and more than 22.8 million children between the ages of 5-16 were out of school nationwide. The hardest-hit province, Sindh, has had nearly 16,000 schools destroyed alone. Thousands of schools were used to house displaced families. More than 400 children were killed in the floods, and many more got injured.

Likewise, the flash floods of June 2022 in Bangladesh affected 3.7 million people in 11 districts in the northern region, of which 1.9 million were women and girls.  A key finding of a rapid gender analysis undertaken by the Gender in Humanitarian Action Working Group states that 60 percent of women surviving on daily wage and rearing livestock lost their incomes.  Most affected households had no food stock and had to survive on food relief. The dry food supplied as relief was not sufficient to cover all affected households’ needs. The flooding caused a serious reduction in the food intake of those families. It was estimated that 60,000 women were pregnant in the affected area, and more than 20,000 births were expected to occur in September 2022.

In the risk framework of the Fifth Assessment Report of IPCC, vulnerability to climate change impacts is inseparably linked to adaptive capacity. The relationships between gender inequality and adaptation capacity span from unequal access to resources and opportunities to stereotypical socio-cultural norms. It is clear from numerous empirical research that social and gender inequalities are present in all spheres of human development, which is essentially why women and girls are disproportionally impacted.

The IPCC’s Sixth Assessment Report has identified South Asia as particularly vulnerable to the impacts of climate change in the coming years, with critical implications for marginalized and disadvantaged communities including women and children. Unfortunately, climate disasters further reinforce the existing gender inequalities, thereby pushing rural communities into the peril of food insecurity. As a result, they become more vulnerable and incapable of bracing for future hazards and risks.

So, what could be the long-term strategy to empower women to build climate resilience for food security?

In South Asia, food security and nutrition have not improved significantly despite the region’s satisfactory economic growth. We are now barely seven years away from 2030, the Sustainable Development Goals (SDG) target year.

The irony is that the leap toward the SDG is growing wider each year, while the clock is ticking. Working for SDG 2, 5 and 13 (Zero Hunger, Gender Equality and Climate Action) requires a holistic approach towards empowering rural women in climate-smart agriculture by supporting them through inclusive policies and practices.

The State of Food Security and Nutrition in the World Report 2022  explains a growing gender gap in food insecurity reflecting that world hunger rose further in 2021 (worsening inequalities across and within countries.

Asian Disaster Preparedness Center (ADPC) through its Climate Adaptation and Resilience for South Asia (CARE for SA) project recently completed mapping and assessing of gender landscape in climate-resilient agricultural policies and practices in three South Asian countries (Pakistan, Bangladesh, and Nepal). Key findings highlight untapped opportunities for governments and other relevant stakeholders to take forward toward not just achieving SDG 5, but also building resilience in the face of food insecurity.

Immediate attention is required towards building and strengthening rural women’s and youth networks and enhancing their linkages with extension services; Engaging private sectors in investing in climate-smart tools and machines that are sustainable and women-friendly; These tools need to be marketed with government subsidies and/or insurance coverage; Harmonizing and strengthening capacity at provincial and local levels on the concept and process of empowerment of women and youth engaged in climate-smart agriculture; Enhancing close coordination among respective National Disaster Management Authorities, concerned sectoral ministries, and province and district level Women Development Departments in the three countries.

Resilience, semantic satiation, conflation, and Maslow’s hierarchy: I can only take so much!

By Joshua Anthony, on 24 August 2022

Author: Dr Chris Needham-Bennett


I am getting worried with hearing ‘resilience’ used incautiously. The word (a general noun) which, once a welcome umbrella term to describe the results of the contributory disciplines of business continuity, disaster recovery, crisis management, emergency response, etc., has become a hackneyed media mantra. The England middle order cricket team batsmen, the Lioness’s England football team are ‘resilient’, a company or local council has ‘built in resiliency’ (whatever that is). The Ukrainians are resilient. My local community needs to achieve resilience. I need to achieve personal resilience for my mental well-being; I am not sure to what?

This blog makes two fundamental points, the first is a conflation of resilience with mental well-being, stress management and associated issues, the second is the overuse of the term and a consequent diminution of its genuine meaning.

Alexander (2013)[1] (noting several other authorities), cautioned that resilience might not have the ‘power’ to be a paradigm, yet almost a decade later—whilst it arguably is far from a paradigm—there is little doubt of a fascination with the phrase and burgeoning academic research[2] (some of which is attributable to climate change research). Moser et al. (2019)[3] note in their abstract that, ‘Resilience has experienced exponential growth in scholarship and practice over the past several decades.…it is an increasingly contested concept.’

The question to my mind is why is there such a fascination with the word? First let us discount hitherto traditional uses of the word which could include its proper application to botany, pharmacology, risk in some instances, material sciences, and metallurgy.

My increasing suspicion is that it is to do with a burgeoning societal self-obsession and narcissism combined with a notion of zero risk. Society appears to have latched onto a phrase which has been hijacked by a quasi-utopian vision which is manifested as follows.

The conflation with ‘well-being’

At the macro level, the OECD measures resilient cities using the criteria outlined below[4]. Some of these seem an expression of good economic common sense. Others such as ‘% of citizens near open space’ seem a little tentative and debatable as to their links to resilience.

 

Four areas that drive resilience. Source: OECD Regional Development[4].

Perhaps as importantly, their definition as to what is resilience is, is tinged with slightly trendy overtones of a ‘brave new world’.

‘Resilient cities are cities that have the ability to absorb, recover and prepare for future shocks (economic, environmental, social & institutional). Resilient cities promote sustainable development, well-being and inclusive growth.’

Sadly, the definition does not really define precisely what the city will be resilient to, rather it is left in vague terms of ‘shock’. It does not mention some of the more critical resilience issues lower down on Maslow’s hierarchy (1943 version; cited by McLeod 2022)[5] such as power, housing, water, sewage, defence, health, and food, without which the ability to live ‘500 metres from services or near an open space or well-being and inclusive growth’ might appear somewhat academic.

At the opposite end of the resilience spectrum, at the individual level, a simple google search of ‘personal resilience course’, offers a spectacular array of over 82 million results. A brief survey of the top five of them indicates that their duration is one day or in some cases half a day. The general view is that personal resilience is a skill or attribute that can be acquired in about 8 hours (the extreme min/max range for the duration of such courses appears to be 90 minutes to a 12-week period).

Robertson et al. (2015) expressed some reservations as to the evidence of the efficacy of such courses. Naturally since 2015 more evidence might be apparent but truly longitudinal studies of the ongoing effect of course completed a decade ago are yet to be available. Their practitioner notes state that,

‘Despite conceptual and theoretical support for resilience training, the empirical evidence is tentative, with the exception of a large effect for mental health and subjective well-being outcomes.’[6]

One BBC report cites Dr Michael Pluess from Queen Mary University of London who is testing for the resilience gene, in which case if discovered it would potentially invalidate the courses cited above.

There is a real danger that resilience, which is a fundamentally practical issue at both the macro and micro level is suborned by the burgeoning but evidentially limited literature on resilience’s relationship to well-being, inclusivity, and mental health. Such links also veneer the unpalatable hard choices that real resilience demands. Put as simply as possible we all might live near open spaces and be very inclusive, but if London’s water supply remains dependent solely on abstraction from the rivers Thames and Lee[7] then it does not matter how ‘positive’ you might feel about the City in about 20 years you will not have enough to drink (perhaps counterintuitively based on a multi-year average, London has only 100mm more rainfall than Jerusalem)[8].

Semantic Satiation

But is there any evidence that the overuse of a word diminishes somehow its value. Broadly speaking yes there is, and it is technically called ‘semantic satiation’. Smith and Klein (1990) noted that ‘Prolonged repetition of a word results in the subjective experience of loss of meaning, or semantic satiation’[9]. At risk of oversimplifying their diligent study, it works something like this; on a relatively infrequent basis I inform my partner that I love her. It seems to cheer her up. If I informed her of my love on a daily basis she would be delighted for a while, then she would suspect that I am having an affair, then she would get bored with it and then perhaps later even angry. The phrase would become increasingly less meaningful and impactful.

At a more serious level it does seem to me to do some harm. In reality a lot of ‘building resilience’ is really risk mitigation or some type or diversification in the case of supply chains. If for instance, we take Markovic’s 1952 diversification theory[10] (disputed by later critics) it does supposedly make an investment portfolio more resilient to market volatility, but the critical issue or activity is diversification which is a ‘thing’ in its own right with a word all of its own to describe it. Now one can make the argument that the end result is a more resilient portfolio, but one should not be tempted to change resilience to an activity which requires it to be a verb. Diversify is the verb or ‘doing word’; resilience is the result. Similarly, if we claim that all activities are resilience measures it somehow diminishes the utility or worth of risk assessments, risk mitigation, plans and responses all of which combine to achieve resilience.

Conclusion

It might be easy to dismiss these concerns as semantic academic posturing yet the power of words, their definitions, associations, and nuances are what will shape the future of resilience. I would wish resilience to remain practical, efficacious, and most importantly simple. Let us leave resilience as an ambition or end state that is achieved through an array of distinct professional activities. Let us also ensure that the fundamental hard and often costly problems associated with resilience are not whitewashed with an ephemera of pleasantries normally found at the higher altitudes of Maslow’s hierarchy of needs. There may well be benefits to stress or coping management courses but let us call them just that, not personal resilience.

Humanitarian shelter and home-based work

By Victoria Maynard, on 7 July 2022

The future of humanitarian response is urban.  More specifically, the future of humanitarian response is in informal settlements in urban areas in the Global South.  In these contexts 20-50% of households run small home-based enterprises from within or around their home.  It is also estimated that home-based enterprises generate 50-75% of household incomes.  Home-based enterprises can take many forms.  They can be as simple as a table or chair—from which to cook, sew or provide haircuts; or the use of a room or window to make or sell goods and services. They include kiosks and extensions, to the use of a whole floor of a home for a shop, café, or workshop.

Despite the prevalence and importance of home-based enterprises to households living in informal settlements, they remain largely overlooked within the humanitarian shelter and settlements sector. The latest edition of the Sphere Handbook (2018) states that shelters must be “located to provide access to livelihoods opportunities” which should be “close to the shelter”. Similarly, Shelter Projects Essentials (2021) includes a diagram which states that shelter should be “near my work”.  However, for many families their home is itself the place where they earn a living—so shelter recovery plays a critical role in their ability to restart their livelihoods.

In addition, if we ignore home-based enterprises then we are ignoring women. Most home-based enterprises are run by women and at least 50% more women work in households with home-based enterprises than those without.  We are also missing a massive opportunity to help women restart their livelihoods. In 2005 Sheppard and Hill argued that home-based enterprises are “the single most important income source for the populations most affected by disaster”.  While the contribution of shelter to home-based enterprises is “the most important way that shelter can support economic development in post-disaster societies”.

Recognising the importance of this topic, in 2021 Beth Simons, Elizabeth Wagemann, and I published a chapter on ‘Supporting the Recovery of Home-Based Enterprises’ in the Roadmap for Research for Humanitarian Shelter and Settlements Assistance.  In April 2021 we hosted a breakout group at UK Shelter Forum 27, during which participants shared lots of examples from practice. These included: using porches as small shops or places of work; using the space around shelters for growing crops for sale; using the space inside the shelter for making crafts; and using the roof for food storage. One participant commented that “every single woman” in a project in Burkina Faso was engaged in home-based enterprise and “most of the requests for housing improvements are linked to those activities”.

We have since completed a scoping study to examine the relationship between housing and home-based work (HBW) in development contexts.  The study considered (1) The effects of housing on HBW and (2) The effects of HBW on housing. 1837 potentially relevant studies were identified in academic and grey literature and 12 studies from Latin America and the Caribbean (LAC) were then selected for further study.  Each of the LAC studies were read and coded, using a combination of inductive and conductive approaches. Results were then presented in terms of: effects identified at household or settlement scale; and those identified in multiple studies with consistent findings, multiple studies with inconsistent findings, and single studies.

Our results reaffirmed the “symbiotic relationship” between housing and HBW—with livelihood and household activities taking place at different times of the day in the same space.  We also found that households are more likely to engage in HBW if they:

  • Live in advantageous locations within the city, neighbourhood, or building;
  • Are subject to favourable regulation (or lack of regulation);
  • Do not feel at risk from natural hazards or security threats;
  • Live in larger houses on larger plots, with adequate appliances and services;
  • Have greater tenure security.

We suggest that these can be called the characteristics of ‘supportive housing and settlements’.  In settlements where these characteristics are present more households are likely to engage in HBW. Households which engage in HBW develop more sustainable and resilient livelihoods—as a result of increased financial assets and greater diversity of income sources. Income from HBW is often invested in housing improvements such as purchasing appliances, installing services, or improving the quality or quantity of space in or around the home. Improvements like these in turn generate more supportive housing conditions, enabling the household to sustain, expand or diversify their HBW.

While these results are based on literature from development contexts, they are relevant to humanitarian shelter and settlement programming. For example, is the type and prevalence of HBW included in vulnerability and capacity assessments?  Do humanitarian shelter programmes allow enough space within and around shelters to allow households to engage in HBW? Do they enable households to take on HBW to finance shelter self-recovery or build their long-term resilience? Do they consider the positive contribution of HBW to meeting the day-to-day needs of their communities?  Or do restrictive policies, regulations, and lack of tenure security limit the ability of households to engage in HBW?

Our next steps are to: gather empirical evidence from humanitarian contexts in LAC; compare the results of the LAC scoping study with the documents we found from other continents; and undertake a broader literature review to investigate the relationship between HBW and shelter recovery and/or resilience in humanitarian contexts. Join us at the Shelter Meeting in Geneva (or online) on Friday 8th July for an update on our ongoing research in LAC or join our mailing list for future updates.
