Online tools can help people in disasters, but do they represent everyone?

With natural hazard and climate-related disasters on the rise, online tools such as crowdsourced mapping and social media can help people understand and respond to a crisis. They enable people to share their location and contribute information.

But are these tools useful for everyone, or are some people marginalised? It is vital these tools include information provided from all sections of a community at risk.

Current evidence suggests that is not always the case.

Online tools let people help in disasters

Social media played an important role in coordinating response to the 2019 Queensland floods and the 2013 Tasmania bushfires. Community members used Facebook to coordinate sharing of resources such as food and water.

Crowdsourced mapping helped in response to the humanitarian crisis after the 2010 Haiti earthquake. Some of the most useful information came from public contributions.

Twitter provided similar critical insights during Hurricane Irma in South Florida in 2017.

Research shows these public contributions can help in disaster risk reduction, but they also have limitations.

In the rush to develop new disaster mitigation tools, it is important to consider whether they will help or harm the people most vulnerable in a disaster.

Who is vulnerable?

Extreme natural events, such as earthquakes and bushfires, are not considered disasters until vulnerable people are exposed to the hazard.

To determine people’s level of vulnerability we need to know:

  1. the level of individual and community exposure to a physical threat
  2. their access to resources that affect their capacity to cope when threats materialise.

Some groups in society will be more vulnerable to disaster than others. This includes people with immobility issues, caring roles, or limited access to resources such as money, information or support networks.

When disaster strikes, the pressure on some groups is often magnified.

The devastating scenes in New Orleans after Hurricane Katrina in 2005 and in Puerto Rico after Hurricane Maria in 2017 revealed the vulnerability of children in such disasters.

Unfortunately, emergency management can exacerbate the vulnerability of marginalised groups. For example, a US study last year showed that in the years after disasters, wealth increased for white people and declined for people of colour. The authors suggest this is linked to inequitable distribution of emergency and redevelopment aid.

Policies and practice have until recently mainly been written by, and for, the most predominant groups in our society, especially heterosexual white men.

Research shows how this can create gender inequities or exclude the needs of LGBTIQ communitiesformer refugees and migrants or domestic violence victims.

We need to ask: do new forms of disaster response help everyone in a community, or do they reproduce existing power imbalances?

Unequal access to digital technologies

Research has assessed the “techno-optimism” – a belief that technologies will solve our problems – associated with people using online tools to share information for disaster management.

These technologies inherently discriminate if access to them discriminates.

In Australia, the digital divide remains largely unchanged in recent years. In 2016-17 nearly 1.3 million households had no internet connection.

Lower digital inclusion is seen in already vulnerable groups, including the unemployed, migrants and the elderly.

Global internet penetration rates show uneven access between economically poorer parts of the world, such as Africa and Asia, and wealthier Western regions.

Representations of communities are skewed on the internet. Particular groups participate with varying degrees on social media and in crowdsourcing activities. For example, some ethnic minorities have poorer internet access than other groups even in the same country.

For crowdsourced mapping on platforms such as OpenStreetMap, studies find participation biases relating to gender. Men map far morethan women at local and global scales.

Research shows participation biases in community mapping activities towards older, more affluent men.

Protect the vulnerable

Persecuted minorities, including LGBTIQ communities and religious minorities, are often more vulnerable in disasters. Digital technologies, which expose people’s identities and fail to protect privacy, might increase that vulnerability.

Unequal participation means those who can participate may become further empowered, with more access to information and resources. As a result, gaps between privileged and marginalised people grow wider.

For example, local Kreyòl-speaking Haitians from poorer neighbourhoods contributed information via SMS for use on crowdsourced maps during the 2010 Haiti earthquake response.

But the information was translated and mapped in English for Western humanitarians. As they didn’t speak English, vulnerable Haitians were further marginalised by being unable to directly use and benefit from maps resulting from their own contributions.

Participation patterns in mapping do not reflect the true makeup of our diverse societies. But they do reflect where power lies – usually with dominant groups.

Any power imbalances that come from unequal online participation are pertinent to disaster risk reduction. They can amplify community tensions, social divides and marginalisation, and exacerbate vulnerability and risk.

With greater access to the benefits of online tools, and improved representation of diverse and marginalised people, we can better understand societies and reduce disaster impacts.

We must remain acutely aware of digital divides and participation biases. We must continually consider how these technologies can better include, value and elevate marginalised groups.

Mapping together for improved healthcare delivery: the HCRI humanitarian mapathon, 2019

Maps, humanitarianism, and public participation

High quality and up-to-date maps and geographic information at appropriate spatial scales are vital for effectively preparing for and responding to disasters and humanitarian crises. Risk reduction activities, resource and service delivery, rescue and emergency care, information flows and risk communication, impact assessments and disaster recovery are all dependent on spatial information. In some parts of the world national/government maps, and even Google maps, are inadequate or incomplete, and alternative maps are required.

Public participation in mapping for disaster response and humanitarian crises has increased significantly in the last decade. Sometimes referred to as digital humanitarianism or digital volunteering, or more broadly volunteered geographic information (VGI), the practices of private citizens contributing geographic information for crisis management has been facilitated by technological advancements such as broadband internet and Web 2.0, cloud storage, GPS and smartphones.

Despite limitations, including digital divides and unequal online participation, and data quality concerns, among others, VGI has provided highly useful maps and geographic information to aid in a variety of humanitarian crises, with the use of OpenStreetMap in response to earthquakes in Haiti (2010) and Nepal (2015) as key examples.

What is a mapathon?

OpenStreetMap (OSM) is an online, crowdsourced mapping platform – a bit like Google Maps but created by people like you! Volunteers work independently or collaboratively to add and edit content on the global digital map.

A mapathon is a bit like a ‘mapping party’, whereby people come together to complete a whole load of OSM mapping in a relatively short period of time. The idea being that with everyone working together in just a few hours we can make a BIG contribution! Importantly, mapathons are usually accompanied by free pizza and other fun snacks for the volunteers!

Volunteers work together to add features to poorly-mapped regions

The HCRI humanitarian mapathon

In March 2019 we held our annual mapathon in the Humanitarian and Conflict Response Institute (HCRI), University of Manchester. With colleagues in Geography, we were aiming to contribute to an ongoing project coordinated by Dr Jonny Huck seeking to improve delivery of healthcare and prosthetic limbs to people who were mutilated during conflict in North Uganda. The mapping involved tracing basic information, such as people’s homes, on satellite photographs.

No mapathon is complete without pizza!

Around 40 students, academic and support staff from HCRI and across the university volunteered to contribute ~20,000 features (roads, huts, buildings etc) to the poorly mapped region of Acholi in Uganda (Wow!). This open source mapping and data will directly help in reaching people with urgently needed healthcare.

Mapping is also valuable to volunteers

“The mapathon was a great way to engage with people who have varying levels of map/geographic information systems (GIS) experience. The process of mapping roads, houses, tracks, buildings etc was very simple. The handouts of how to complete the tasks meant that it was straightforward and you constantly have a source to refer back to. The project as a whole meant that the time I gave felt worthwhile and like I was really making a difference to medical logistic teams in Uganda. I would highly recommend anyone to come along to the next event and get involved; it’s a great way to spend a couple of hours.
– Rach, HCRI MSc student.

“I think it was particularly useful for students of GIS and disasters, in which we critically analysed VGI to participate in the very digital volunteerism we were analysing. It was a more visceral and tangible demonstration of the quirks of geographic information that we were discussing in class (e.g. map projections) even if these particular quirks were relatively trivial.
It was nice to bring together people who I’d never seen before across the school and get a feel for what a larger group VGI volunteering effort looks like. I think a lot of people got a fair bit out of it, and I left the event feeling good. The software is super simple and easy to learn and having a few skilled people there to help when problems arose was enough to get everybody up and running.”
Mike, HCRI MSc student.

Mapathons are enjoyable and rewarding for volunteers

Get involved!

YOU can contribute too!
You don’t need any prior mapping experience, just a computer and an internet connection, and you can map anytime. Visit http://huckathon.org/ to learn more about the North Uganda project and start mapping! Each feature you add to the map could mean a new limb for someone who has been injured by conflict. Better still; why not host your own mapathon?!

The HCRI mapathon was funded by the School of Arts, Languages and Cultures (SALC) Social Responsibility and Cultural Engagement fund, University of Manchester.

AAG Annual Meeting, Chicago 2015: Reflections

Recently I attended the Association of American Geographers 2015 annual meeting in Chicago, IL, along with several thousand other “geographers” from around the world. Being the largest academic geography conference in the world, even navigating the program was a little overwhelming with over 6000 items, let alone the event itself. But that volume of presenters also means a lot of interesting research, and this post attempts to document some of that. I won’t be listing everything I experienced, but rather just summarising some of my highlights from the week.

Tuesday April 21

First up on the first day was my own presentation, as part of the session Advances in Geospatial Emergency Management, organised by Professor Matt Duckham at the University of Melbourne (one of my associate supervisors) and Professor Mark Horner at Florida State University.

My paper, Engaging Communities in Disaster Risk Reduction through Volunteered Geographic Information: A case study of bushfires (wildfires) in Tasmania, Australia, was really a broad overview of my PhD research. The paper described how VGI represents shifts in the way geospatial information is produced, shared, used, and experienced, resulting in changes to social practices, top-down approaches to mapping and information dissemination, and the broader disciplines of geography and GIScience, with significant implications for various applications, including emergency management. This research considers the potential of VGI to transform disaster management by thinking about VGI as a social practice and not simply a type of information.  This leads to thinking about change in cultural practices in emergency management away from authoritative top-down systems. Giving power to citizens through VGI aids in sustaining community involvement in disaster management, changing behaviours, and ultimately increasing disaster resilience. The paper called for a need to critically assess the role of VGI in the important disaster management phase of preparedness by emphasizing the majority of research in this field to date has only considered disaster response. The research presented focused on VGI for increasing bushfire preparation engagement in Tasmania, outlining key research methods, such as community surveys, interviews with emergency management professionals, and community participatory mapping workshops, along with some preliminary findings.
In the same session I found the impromptu presentation by Matt Duckham on some of the work from his RISER (Resilient Information Systems for Emergency Response) project very interesting. Matt argued that in a time of increased looking to social media for crowdsourced information in disaster management, there are other sources of information from that crowd that are both highly useful and sometimes perhaps more reliable. He noted that in the event of bushfire actually finding the exact location of the fire can be a real challenge, and demonstrated a model that predicted fire locations using crowdsourced data in the form of calls to the emergency services with impressive accuracy. There is a special journal issue in ‘Computers, Environment & Urban Systems’ calling for papers that accompanies this session. More details and submission information can be found here.

Later in the day the panel session, CyberGIS symposium: frontiers of Big Data and urban informatics, chaired by Vonu Thakuriah of the Urban Big Data Centre, raised some interesting questions around the benefits and challenges of big data, researching with big data and theory versus data driven models, privacy, the aggregation of data and industry ownership, and democratization and the notion of an open data economy.

Wednesday April 22

In the morning session Analysing resilience through disaster response, risk perception and risk communication, research in Portugal showed emergency authorities to be under-prepared for ‘lower risk’ emergencies, such as hail and lightning strikes (as opposed to floods, earthquakes etc), with significant negative implications for affected communities. PhD research modelling the coverage and response times of fire services in a province of Ghana was presented, using GIS to improve the efficiency and effectiveness of existing systems while trying to predict where new fire stations should be most strategically positioned to best serve the communities in the area. What was striking in this paper to me was the difficulties associated with obtaining data in particular countries in the world, such as Ghana. The concept of tipping points in resilience theory was described by Rafael Calderón-Contreras, where at a particular point a system will either cope with stress and remain the same or change to a new state. Resilience, being ‘ready’ for disaster, and failures of authorities were common themes in this session.

One paper I particularly enjoyed in the session Utilising Citizen Science for supporting geospatial applications was BikeMaps: A citizen science web-map for cycling safety presented by Trisalyn Nelson from the University of Victoria.

BikeMaps has citizens contribute their local cycling knowledge (hazards, theft, accidents, near-misses etc) and then analyses and visualizes the data with the aim to make biking safer. The project seems highly useful and is gaining interest in places all over the world. They’ve employed some pretty fun engagement strategies, with my favourite being placing BikeMaps branded drink bottles on 500 parked bikes across the city for unsuspecting cyclists to find when they return to their bikes (information on the project and how to contribute is included inside the bottle).

The other highlight of the day was a Vespucci reunion over lunch with Muki Haklay, Victoria Fast, Cheli Cresswell, Cristina Capineri and Antonello Romano. I met these guys at a summer school on VGI and Citizen Science in Italy last July so it was great to see everyone and learn how they’re doing with their research.

Thursday April 23

I attended an Esri workshop on teaching Web GIS. The workshop provided a guide for teaching Web GIS in classrooms. It was interesting and useful in thinking about my current teaching as a GIS tutor and for when I may be writing courses myself one day. But it was also just really interesting for myself to be exposed to a whole range of new platforms and possibilities for GIS mapping provided through Esri and ArcGIS online that I had never really explored before. Things like making interactive web maps, custom and mobile applications, easy ways for the public to contribute volunteered geographic information, and the general simplicity and quality of some of the online tools. I started to rethink how I make my maps now and got pretty excited about revisiting some of my past projects with these new tools, as well as what new projects could be possible. Really cool!

The panel session New Directions in Mapping: Open Source, Crowd-sourcing and “Big Data” chaired by Matthew Zook raised some interesting debates. How do we define ‘open’ and is it the same in theory and implementation? What implications might an increase in the ubiquity of mapping and the use of passive data have for expert geography and expert map-makers? What about those citizens not represented in the ‘crowd’? Are the gaps in crowd data more in content than in space? Probably both. Those with the loudest voices have their issues heard more (and therefore their content mapped) excluding ‘smaller’ problems (smaller in terms of voice, not importance), and there are gaps in space, E.g. how does the crowd map private land? What does opting-in mean when you can’t use a service unless you agree to terms of service? Opting-in implies there should be more control over choice than that doesn’t it? Will people opting-out become an issue for applications relying on crowd data?
How do crowd data and authoritative data compare on quality? It was argued in the panel that all data has issues, it’s just that this is recognised and accepted in crowd data.

Friday April 24

Friday was mostly taken up by sessions run by Muki Haklay around motivation and enthusiasm in citizen science, and around OpenStreetMap studies (the online public mapping platform recently celebrated it’s 10th Birthday). Britta Ricker spoke about the use of drones for motivating students into science work. Drones bridge the gap between the imagery needed for science over smaller spatial scales and the spatial and temporal limitations of pubic satellite data. People seem genuinely excited by drones, but we need to also remember why are we using them (why is a drone needed for the research objective etc). I wondered if the increased engagement with the technology also extended to increased quality of learning for the students – a point I think relevant to my work on exploring the use of VGI technologies for increasing community engagement in bushfire preparation. In a project on conservation and hunting lion fish in the Caribbean, Brittany Davis then spoke about balancing participant’s enthusiasm to hunt the animal for recreation with enthusiasm to participate in the science with collection of accurate and useful data and the overall aim of conservation. For many in this study it seemed the motivation for participating was the access for them to kill the fish, not the important data collection.

Muki Haklay gave a talk on OpenStreetMap, thinking about how it relates to VGI and to citizen science. He has provided the slides from his talk here. I thought it was very thought provoking and I will end this post with a few points I took away from his talk:

  • Academics needs to be a “critical friend” to projects like OpenStreetMap, they need to be realistic about projects, and they need to learn from each other
  • Projects like OpenStreetMap and other VGI or citizen science projects are not just about the data – they are a social practice
  • In order to best understand you need to do the project yourself, not just study from the outside – participatory research
  • In regards to open research, even if your work can’t be in an open access journal, you can still make it accessible and visible through other means, such as by posting a summary on a blog.

Muki also showed a video (below) made to portray some of the research associated with COST Energic around VGI and indigenous communities. I won’t describe the video too much as you can just watch for yourself if you wish. But I will say it’s a nice video with some very interesting work and I recommend giving it a look.

And so that was some of my highlights of the AAG 2015. Overall I found the experience very rewarding. Being from Australia where much of the research I’m interested in is not so big, particularly around emerging geospatial technologies for community engagement in science, new mapping directions and ‘big data’, and more generally VGI and citizen science studies, meant the conference was particularly giving for me with a vast amount of research being presented in these fields. For emergency management it was somewhat disappointing and encouraging at the same time to see researchers all over the world are grappling the same kinds of questions and challenges in disaster management, namely around resilience building and tensions between community activities, emergent technological solutions, and traditional authoritative emergency management practices. I had my first experience presenting my work internationally, I learnt about a lot of interesting projects,  and I fostered existing research connections and made some new ones. What’s more, I got to experience the fantastic city of Chicago! I may have a sore neck from looking up at all the beautiful big buildings, but that’s okay, because the late night jazz, deep dish pizza and seeing the Chicago Bulls win in the NBA playoffs all make up for that! Now, here is a picture of me with the bean:
