CoP 28 : Good use of data is key to mitigating the climate emergency 

MapAction urges world leaders and stakeholders gathered at COP28 to promote data-driven solutions to improve the lives of people on the front lines of climate change. (A version of this article was first published before CoP27 in Egypt in 2022. It was updated for CoP28 in November 2023. )

In recent years we have seen a large increase in the number of natural disasters worldwide. Regular climate-related disasters are exacerbating water and food insecurity. 

How emergency relief stakeholders and governments coordinate their responses to the climate emergency can impact the recovery of affected communities. That is why good data is key to preparedness and mitigation, especially in locations with limited resources.

As the changing climate ravages and displaces some of the world’s poorest communities, good data use will not prevent such climate-driven occurrences. It can only soften the effects by helping the affected communities, and stakeholders, to be prepared and to coordinate relief strategies. Good use of data in decision-making at key moments can reduce the human cost of the climate emergency. 

“Data, often visualised through maps, can help identify who the most vulnerable people are, where they are, and highlight need,” said Nick Moody, MapAction’s chair of trustees, before CoP27 in 2022. “At CoP27 there was a recognition that while this information is critical during a crisis, it can have an even greater effect if used in advance. MapAction has a huge role to play in helping others to build resilience through data.”

Why MapAction?

Since MapAction’s inception over 20 years ago, the charity has provided data and specialist technical geospatial and data volunteers in more than 140 crises, many climate-related, worldwide. Our team has supported responses alongside UN, regional and national agencies as well as INGOs and local civil society organisations, providing relief to some of the most vulnerable climate-exposed people worldwide.

Our 70+ volunteers come from across the ever-growing range of sectors using data and geospatial technology, bringing a huge diversity of technical expertise. MapAction gives them the training, operational experience and support needed to operate effectively in humanitarian situations. 

Working in collaboration with many emergency relief partners, our teams create unique situation maps, data visualisations, data sets and other products that help coordinate disaster relief using the best available information in the most insightful ways. The improved decisions they enable can help mitigate, for example, the impact of droughts, floods, hurricanes, earthquakes, famines and health crises, to save lives and protect communities. In 2023 alone, MapAction has provided data products, volunteer mapping teams or experts to support emergency response, anticipatory action programmes or capacity building in a dozen countries in five continents.

From response to anticipation

While MapAction’s initial expertise was in support of emergency response, our work is increasingly moving into early warning and preparedness. Anthropogenic climate change has been proven to alter both the likelihood and the severity of extreme weather events around the world, and the growing frequency of these can be predicted, if not precisely then generally. Being ready to spot the indicators, triggering early support for anticipatory action can be life-saving. Predictive analytics can allow us to define the mechanisms that trigger these actions by analysing current and historical data and developing models, as long as the data is reliable.

“It is more important than ever to be able to respond effectively to such events, but also to be able to anticipate them, in order to more effectively mitigate their impact,” Daniele Castellana, former lead Data Scientist at MapAction, commented before CoP27. “Through our collaborations with the Centre for Humanitarian Data and the Start Network, MapAction has been working on this flourishing component of humanitarian aid.” MapAction launched its own InnovationHub in 2022.

Early action is one of the most effective ways to address the ever-growing climate impacts. That is why MapAction has partnered with the START Network, a coalition that focuses on humanitarian action through innovation, fast funding and early action; Insurance Development Forum is also a partner in this work. START Network brings together 55 international non-governmental organisations and 7,000 partners worldwide. MapAction is also working with INFORM to support updating forecast and risk models with select national disaster management agencies worldwide.

From commitment to action

MapAction has made concrete commitments to actively seek solutions to reduce the impact of climate change. In October 2021, we signed the Climate and Environment Charter for Humanitarian Organisations. The charter was developed by the International Committee of the Red Cross (ICRC) and the International Federation of Red Cross and Red Crescent Societies (IFRC), and guided by a 19-person strong Advisory Committee which included representatives of local, national and international NGOs, UN agencies and National Red Cross and Red Crescent Societies, as well as academics, researchers and experts in the humanitarian, development, climate and environmental fields.

Signing that charter commits us to being a part of the solution and helping people adapt to a changing climate and environment. It will also help strengthen our own resolve and efforts to be environmentally sustainable. Most of all, it recognises that our efforts must be a collective endeavour – no organisation can tackle this alone.

Together with a growing range of partners, looking to engage ever more locally, we are using geospatial data, data visualization and data science to start laying the groundwork for climate resilience. The objective is to improve preventive actions and strategies in humanitarian response. 

Because what we map today we can mitigate tomorrow and in the future. That is why the science of how we source, analyze, shape, share and deploy data must be at the heart of all current and future discussions on adapting to climate change.

MapAction excited to announce Colin Rogers as new Chief Executive

Colin Rogers will take over as MapAction’s Chief Executive from Liz Hughes OBE in October 2023. 

Currently Head of Disaster Preparedness and Emergency Response at Plan International, Colin brings over 25 years of humanitarian experience at country, regional and global levels. He has previously worked in leadership roles for Médecins Sans Frontières, International Rescue Committee, Oxfam GB and Care International UK. 

Colin has led or advised on many operational responses including rapid onset, conflict, displacement, protracted disease outbreaks and pandemics. He is a strong advocate for and practitioner in building regional and local capability in preparedness and response, a key aspect of MapAction’s strategy. 

He brings significant experience in the development of non-traditional strategic partnerships, which are increasingly important in a changed funding and operational landscape. His academic background and early career were in Health, an area of increased focus in MapAction’s strategy.

Colin was also the first elected President of Sphere, supporting the development and review of global humanitarian standards and quality initiatives, reflecting his commitment to welfare, safeguarding and professionalism in the field. 

“I am delighted to be able to make a contribution to an organisation with such a great reputation for enhancing decision-making in the humanitarian sector and helping local organisations to reach the most vulnerable,” said Colin. “In doing so, I am committed to MapAction’s values of innovation, collaboration and maintaining the highest of humanitarian standards,” he added. Stay tuned to learn more about Colin’s vision for MapAction in the coming weeks and months.

MapAction urges wider adoption of GIS for disaster resilience at UN Expert Meeting

MapAction’s Head of Programme Development spoke at the UNGGIM this week, promoting the efficiencies that can be gained by effective use of geospatial services to meet the priorities of the  Sendai Framework for Disaster Risk Reduction in understanding risk and vulnerability, governance, financing and especially in early warning and preparedness to respond in emergencies. The UNGGIM is the UN Committee of Experts on Global Geospatial Information Management.

MapAction’s Alan Mills adresses UNGGIM meeting. Aug 2023

The full text of Alan’s statement is as follows.

I make this statement on behalf of the Not for Profit Organization, MapAction. MapAction notes the report of the Working Group on Geospatial Information and Services on Disaster and thanks the group for its efforts over the intersessional period.”

“We remind the Expert Committee that the Sendai Framework for Disaster Risk Reduction, adopted by 187 member states of the United Nations has seven years remaining to deliver its targets. The Sendai Framework relies on information management and mapping across its remit, to understand
disaster risk and resilience, to aid the strengthening of disaster risk governance, support investment in DRR and enhance preparedness for effective disaster response.”

“Given the increasing humanitarian demands around the globe, whether from meteorological events and climate change impacts, seismic shocks, food insecurity or displacement, the implementation of the UN-IGIF and application of the guidelines set out in the Strategic Framework of Disasters provides geospatial resource efficiencies in helping to build resilience and support the most vulnerable in our communities.”

“As resilience building is a priority for all your citizens MapAction urges more Member State delegations to actively participate in the working group in disasters, shape its workplan to be robust to address these priorities and demonstrate active implementation of IGIF and the SFD in support of disaster risk reduction.”

“Partners not just from the existing UN geospatial network, the academic network and the private sector network but also geospatial civil society organizations, including MapAction, who have no network presence within this Expert Committee, and non-geospatial practitioners in resilience building and emergency response all stand by to be consulted, provide context, technical innovation and resource to deliver on this remit once direction is given.”

Alan was also a Panellist in the UNGGIM Side Meeting – ‘Authoritative Data in an Evolving Geospatial Landscape‘, promoting the specific data needs of responders to humanitarian crises. MapAction has been a regular attendee at UNGGIM for several years, in our Official Observer Role. Over this time we have contributed to moving the agenda forwards significantly in terms of improved geospatial data availability for humanitarian purposes.

Urgent appeal : Humanitarian Response Fund

Thank you for opening MapAction’s Humanitarian Response Appeal. We need your urgent help as we seek to fund our continuing responses to humanitarian crises in 2023 and beyond. 

If you fund MapAction you won’t be buying blankets, water, shelter or food. You will be making sure that as those items arrive they get to where they are needed most, as quickly as is possible.

The maps we make help to inform the activities of many different streams of aid, making sure that the most up-to-date information is being used to identify the greatest need. Understandably situation maps and data are not the first thing you might think of when hearing about a response, but just imagine trying to plan search and rescue, emergency health care or efficient aid delivery without maps showing you what is happening, where, and just as important, where the needs are.

Roberto Colombo Llimona, Head of the UN OCHA Assessment & Analysis Cell for the first phase of the Turkiye response, had to support humanitarian decision-makers immediately after the Turkiye earthquake. He said: “Investing in MapAction is a great way to support humanitarian operations…supporting Mapaction is supporting response directly”. 

MapAction’s field teams are the most visible part of our activity, but more often MapAction members are supporting situations remotely, making maps, preparing data, each as qualified and experienced as the team members in the field.

Above : MapAction Field Team members working in the UN Onsite Operations Coordination Centre in Gaziantep, Turkiye.

Why Support MapAction?

MapAction has a unique capability to help in humanitarian crises. Turkiye/Syrian Arab Republic is MapAction’s 12th earthquake and our 137th response: we bring a wealth of knowledge, know-how and operational insight.  Immediately after news of this latest devastating earthquake broke, UNDAC, one of many long-standing partners of MapAction, requested support.

MapAction responded immediately, as we always want to do. However there is a significant cost for MapAction to maintain and provide well-trained, well-supported teams, very rapidly. As an organisation we aren’t large enough to receive funds from the big TV and newspaper appeals, so we must raise the money however we can. This is increasingly a combination of trusts and foundations, corporate support, (often from mapping, geospatial and data-related businesses) and private individuals. We are grateful to them all.

If MapAction’s support can’t be provided when its asked for, responses to disasters may be less effective and more costly. Supporting MapAction can save lives, and make scarce resources go further. 

Please help us to continue this vital work. Whilst highly-valued and regularly requested, MapAction’s response missions have no direct funding right now.  We no longer need immediate funding for the Turkiye/Syria earthquake response, but we do need funding for the next mission and those after that, to ensure we can get on the plane without hesitation . Any donation, big or small, matters right now.

Donations can be made direct to MapAction in the UK, or to MapAction USA as a 501c3, who can also receive funds for this urgent work.

Please partner with MapAction to ensure that all aid gets to where it is needed most, for the many people affected by humanitarian emergencies. Thank You.

MapAction’s Volunteer recruitment drive is open – and it’s the most extensive ever! 

Ever watched a disaster unfold on the screen in front of you and wondered if your specialist technical skills could help? Could a a software or data engineer help in a drought response? Is there a role for a project manager or graphic designer in an earthquake? The answer is yes.

MapAction, the non-profit that provides decision-making support in humanitarian crises, has launched a recruitment drive for up to a dozen new volunteers including data science, data engineering, data visualisation, geospatial, software and project management professionals. MapAction’s broadest and most diverse volunteer recruitment campaign ever seeks those looking to give their skills, time and energy to help many of the world’s most vulnerable people (The roles are remote but you will need to be within easy reach of and allowed to travel to the UK for training).

MapAction’s new strategy will see a greater diversity of organisational partners, data specialisms, services and products than ever, as it strives to bring the power of fast-moving advances in data and geospatial analysis to humanitarian crises.

MapAction wants to hear from willing people with professional skills in any of the following fields : 

MapAction needs such skills to support the ever-growing range of information needs for humanitarian decision-making. Traditionally, MapAction helped in the immediate aftermath of disasters: over the last 20 years, our organisation has produced 1000s of maps and decision-making tools for well over 100 humanitarian emergencies. The team has also trained humanitarian partners in the types of maps, data visualisations and other data tools necessary to mitigate emergencies. We have created tools to automate the gathering and quality of critical geospatial base data when an emergency occurs and helped many vulnerable countries and communities to ensure their key data sets are ‘emergency ready’ and available in advance of when they are needed.

Since the organisation’s inception in 2002, MapAction has enabled scores of people like you to contribute their technical skills to solving crises. Back then, MapAction mostly made maps – now a MapAction volunteer is as likely to be asked to design a data dashboard or contribute to a rapid extent flood model as to make a map (although just to be clear, we still love a good map).

MapAction volunteers can contribute their work remotely but we also still send volunteers out on missions when invited. Which is often. Volunteers might go to the heart of humanitarian crisis responses, alongside relevant UN, regional and national disaster management colleagues, providing the data sets and maps that can help emergency relief coordinators make key decisions about aid delivery for affected communities. Or you might be training or supporting local governments or civil society organisations in how to better prepare and use their data in an emergency context.

A MapAction volunteer’s work is challenging and varied but you will always receive extensive training and support before we put you into any situation. Working with data under pressure, and when lives are at stake, is a big responsibility.  

Despite the challenges, MapAction volunteers often find the work highly rewarding. Many have been with us for more than a decade. Most enjoy the opportunity to help mitigate emergencies and crises, to create positive outcomes for vulnerable communities. “There is a great sense of achievement being part of MapAction, it allows me to utilise my professional skills within another context, at the same time providing support to those helping people,” says long-term MapAction member Tony Giles.

MapAction member Rachel Alsop says: “When I went on my first emergency deployment I remember saying that I thought working in consultancy was great preparation, working long hours, with tight deadlines and under considerable pressure. Having a background in data and analytics has been really useful over and above my GIS skills. MapAction is a big commitment but I have loved every year I have spent volunteering and we wouldn’t all be committing our time unless it was also a lot of fun.”

“I wanted to join so I could use my programming skills to make a real, immediate, and positive difference to places in the world that need it. The MapAction staff and volunteers have been more than amazing in welcoming me into the world of humanitarian aid. Through the training days and weekends I’ve spent with them, I’ve had great fun with possibly the geekiest (and I know geeky!) GIS crowd around, made good friends, and felt a sense of great privilege to be part of MapAction’s crucial and respected work with aid agencies worldwide,” adds MapAction member Leon Baruah.

Kirsty Ferris, another MapAction member, says it is the impact that keeps her tied to the role. “I get to make a real impact in devastating situations using GIS, information management and mapping, all of which are areas of expertise that I find enjoyable to use. While the training is intensive and time consuming, the benefits to me personally and professionally are too vast to mention. The volunteers and full time staff at MapAction provide great support, understanding and shared geekiness, there are not many places where you can talk GPS and geodesy with such shared enthusiasm,” Kirsty told MapAction.

As Leon notes, our volunteers receive a lot of support and undergo extensive training to ensure they are ready to work in humanitarian contexts. They meet regularly to exchange ideas, troubleshoot challenges and learn together. MapAction’s annual disaster simulation exercise brings together the majority of the team to ensure maximum preparedness for any emergency. The 2023 edition will be on the Isle of Cumbrae in Scotland.

My London Marathon venture

By Ian Davis, MapAction’s Fundraising & Marketing Director

Ian Davis wearing a MapAction branded running t-shirt which says 'Ian' on it.

I’m 56, unfit and with the build of the wrong kind of Chippendale (short-legged wooden furniture, not under dressed male dancer). So why on earth am I running the London Marathon?

Because I’m raising money for MapAction, an organisation that enables mapping, GIS and data experts to volunteer their time and expertise to humanitarian emergencies. Yes, I know it sounds a bit geeky but what our volunteers can do makes the difference between vital aid arriving to the people who desperately need it, in time or not. MapAction volunteers sometimes work from home, but they are equally willing to jump on a plane, in the middle of a pandemic, and sit in a sweltering tent in Haiti, Guatemala or anywhere else. 

Because, whilst I’ve been grumbling and groaning my way around the highways and byways of Oxfordshire in training, some of our volunteers have been doing just that in support of the response to the recent earthquake in Haiti.

I’ve had my path blocked by the odd deer, dog or heron on my travels, but at least the tarantulas are quiet around Oxfordshire at this time of year, and I don’t worry much about kidnappings or gunfights between armed gangs.

Please remember, by sponsoring me, or any of my fellow runners (see links below), you are really sponsoring the work of our amazing volunteers and this small but very important organisation. By doing it through one of our London Marathon fundraising pages, it’s also really easy to add Gift Aid which makes your donation go even further (and yes, it will make us all feel a little better as we try to complete this epic race).

MapAction supports St Vincent volcano emergency response

MapAction is providing mapping and information management support to the La Soufriere volcano emergency on the island of St Vincent, in response to requests from both CDEMA (Caribbean Disasters & Emergency Management Agency) and UN OCHA’s regional office. 

Explosive eruptions from La Soufriere since April 9th have caused ash clouds to cover much of St Vincent, Bequia and southern St Lucia, as well large parts of Barbados.  Pyroclastic flows have descended from the mountain top, after it was confirmed that the volcanic dome had collapsed. 

Monitoring of the volcano is difficult as existing seismic stations were knocked out and it became dangerous to travel into the area. By the 7 of April, circa 16000 residents had been advised to evacuate following early signs of activity.  The incident has already caused serious need for shelter, PPE and fresh water and is developing. Flooding is now reportedly compounding the situation.

MapAction is currently supporting the situation remotely, having already assembled a dedicated team of three volunteers and one staff member, located in Montserrat, the Turks & Caicos Islands (both in the Caribbean), New Zealand and the UK respectively. All members of the MapAction team will be working remotely due to the travel and other complications of the COVID-19 pandemic, and there are no current plans to send a geospatial team to the affected area, although two of the team are based in the Caribbean region.

The direct mission costs are being met by the German Federal Foreign Office. MapAction’s response capacity has been supported by UK Foreign, Commonwealth & Development Office (FCDO) and the Netherlands Ministry of Foreign Affairs, and we have been working extensively in the Caribbean region on disaster preparedness work thanks to USAID Bureau of Humanitarian Affairs. 

The mapping techniques used in the 3D web mab above are based on recent work by MapAction and the University of Edinburgh, which pioneered 3D interactive webmapping for planning and response to volcanic hazards.

Many of MapAction’s maps and other information products relating to this emergency will be available here as the emergency develops.

MapAction provides support to Hurricane Eta and Typhoon Goni responses

MapAction teams are in action again, this time providing support to the humanitarian responses to Hurricane Eta in Central America and Tropical Typhoon Goni in South East Asia.

Hurricane Eta – A coordinated team of MapAction GIS volunteers is working remotely in support of UN OCHA’s Regional Office for Latin America and Caribbean (ROLAC) as they coordinate the humanitarian response across Central America in the wake of Hurricane Eta. Over 1.8 million people have been affected across Nicaragua, Honduras, Guatemala, El Salvador and Belize. 

Honduras: Tropical Storm Eta Municipalities affected (November 7, 2020) – Honduras

The team are already delivering mapping support for the immediate aftermath of the hurricane and are preparing to deliver 3W and flood mapping.  It is anticipated that further support may also be required with this fast developing situation and we are standing by for requests. You can see the maps and other products produced so far here. You can see further MapAction-aided products on the Reliefweb site.  

Hurricane ETA is a Category 4 hurricane that made landfall in Nicaragua on Tuesday Nov 3rd and moved north through Honduras, Guatemala, El Salvador and then Belize. Eta is now a Tropical Storm and is due to hit Cuba in the next 24 hours. The Central American region has suffered widespread flooding, storm surges and landslides. Honduras, Nicaragua and Panama are under red alerts. Guatemala has also been severely affected. For further situation information see the most recent OCHA needs snapshot and Relief Web update.

MapAction is grateful to the German Federal Foreign Office for supporting our response, as well as to the Netherlands Ministry of Foreign Affairs and the UK FCDO for their continued support of MapAction’s response capacity. 

Tropical Cyclone Goni – This typhoon is affecting people across the Philippines and Vietnam. A member of the team is supporting MapAction partner the AHA Centre (ASEAN Coordinating Centre for Humanitarian Assistance on Disaster Management) as it coordinates the response. You can see the maps and other products here. You can see further products on the Reliefweb site

As UN assessment teams make their way to some of the hardest hit areas, a clearer picture of Typhoon Goni’s impact (known locally as Rolly), which made landfall in the Philippines on Sunday, is emerging. The UN OCHA office reported that as of 6 November, around 1.2 million people (more than 312,500 families) across seven regions have been directly impacted by the disaster. “As more than 21,000 homes were destroyed, many families will remain in long-term displacement,” it reported.

What does ‘Data’ mean to MapAction?

What is MapAction’s ‘humanitarian data landscape?’ At MapAction, we’re working to put data at the centre of how we provide products and services to the humanitarian sector. MapAction’s data scientist, Monica Turner, recently posted  about the work she does in this new role. However, data is a big (and sometimes loaded) term. So what does ‘data’ mean to MapAction? We asked Hannah Ker, MapAction’s Data Scientist whilst Monica is on maternity leave, to explain. 

During a humanitarian crisis, it is vitally important for responders to have information such as which areas are most affected, where vulnerable populations exist and where relevant infrastructure & services (such as healthcare facilities) are located. MapAction provides information products (such as maps) to our partners to help them address these information needs. Unsurprisingly the vast majority of data that we work with at MapAction is geospatial. We aim to use geospatial techniques, such as cartography, to make complex data rapidlly accessible to those responding to humanitarian crises.

The ‘Layers of data’ page (see diagram below) from our Example Product Catalogue provides a useful framework for thinking about how many different datasets are processed and combined into a meaningful final product.

Firstly, we can think of the data that is input to our basemap or initial reference map of a given area. This data often reflects features such as administrative boundaries, land elevation, settlements, and transportation infrastructure. Secondly, we have baseline data that provides demographic information about the area of interest, such as population numbers and numbers of schools. 

Our last data layer includes situational information that is relevant to the humanitarian context at hand. The kinds of data relevant for this layer can vary significantly depending on the circumstances. This data is also likely to be the most dynamic and temporally sensitive. For example, it may be used to show change over time as a crisis evolves.

All of this data can come from a variety of sources. The Humanitarian Data Exchange (HDX), developed and maintained by the UN OCHA Centre for Humanitarian Data, is a repository that holds over 17,000 datasets from more than 1,300 different sources. These datasets come from what we might think of as ‘authoritative’ sources of information, such as the World Bank or the World Food Programme.

In particular, MapAction frequently uses the Common Operational Datasets of Administrative Boundaries (COD-AB) that are published and maintained by the UN Office for the Coordination of Humanitarian Affairs (OCHA). It can be challenging to access complete and up-to-date administrative boundary data, so the CODs attempt to provide standardised, high quality data that can be used to support humanitarian operations.

OpenStreetMap (OSM) also provides a valuable source of geospatial data. This ‘Wikipedia of maps’ is an entirely crowdsourced map of the world. In theory, anyone, anywhere in the world (with an internet connection) can contribute to OSM. At MapAction, we use OSM as a source of data for features such as settlements and transportation infrastructure. MapAction is a partner of the Missing Maps project, hosted by OSM which seeks to crowd source the gaps in maps in available maps.

So why can’t we just use maps that already exist, like Google Maps?, one might ask. Why all these complex data layers? Why spend so much time finding data when it’s already all there?

Platforms such as Google Maps, Waze, and Apple Maps are commonly used as day-to-day navigation tools for people in many parts of the world. However, such existing tools do not provide the flexibility that is often required when managing and presenting geospatial data in humanitarian scenarios. As these tools are privately-developed, individuals and organisations do not always have the ability to manipulate or style the underlying data to suit their needs. These platforms were not created specifically for humanitarian use-cases, and so may not always include the information that meets the operational requirements of humanitarian contexts, such as locations of damaged buildings or the extent of a flood.

OSM’s Humanitarian map style, for example, shows some of the unique data styling that may be required in humanitarian contexts. Moreover, there are many parts of the world with human settlements that are not present (or poorly represented) on existing maps, as is demonstrated by efforts from organisations such as the Humanitarian OpenStreetMap Team and the Missing Maps initiative. These challenges mean that there is no existing ‘one size fits all’ mapping platform that is capable of providing and presenting all of the information that is needed in humanitarian contexts. 

Finding high quality geospatial data is an ongoing challenge for us at MapAction. Geospatial data quality is a multifaceted concept, and includes dimensions such as up-to-dateness, positional accuracy, logical consistency, and completeness. The image below, for example, shows a geometry problem that we often face with administrative boundary data. Notice the gap in the border between Chad and the Central African Republic. Lack of standardisation in this data between different countries and organisations, or out of date data can result in such misalignment. Due to the political sensitivity that is associated with boundary data, it is important to ensure that the data that we use is as accurate as possible. 

Our ongoing work around the Moonshot project seeks to develop tools that can help us to automatically detect and address quality issues such as these. Keep an eye out for future blog posts where we will address some of these technical challenges in greater detail. 

At the end of the day, we’re working to make complex situations better understood. Humanitarian crises are incredibly complex, and accordingly, can be associated with complex datasets and information. By selecting high quality datasets and visualising them in clear and accessible ways, we intend for our humanitarian partners to be able to make informed decisions and deliver effective aid to those in need.

Caribbean Hurricane Response Mapping Update

Humanitarian access map of Dominica (updated regularly).

Hurricanes Irma and Maria have left a trail of damage and devastation across parts of the Caribbean in the past month.

MapAction were able to respond quickly and in numbers to this crisis, with good local knowledge and networks in the region. So far eight MapAction volunteers have supported the response in the field, with one more team member due to fly out this week. Many others have been supporting  the field teams remotely.

MapAction teams have worked in support of the relevant national government disaster management agencies, usually through CDEMA (Caribbean Disaster Emergency Management Agency) and UNDAC (UN Disaster Assessment and Coordination).

The work has required much movement between islands, both to provide GIS support where it was needed and to avoid being caught in the direct path of the hurricanes. MapAction volunteers have been operating in Anguilla, Antigua, Barbados, British Virgin Islands, Dominica, Grand Turk, Haiti, Jamaica and Providenciales.

As of Sept 26th MapAction has three people remaining on Dominica with all others now safely home. With Dominica receiving a direct hit from Category 5 Hurricane Maria MapAction volunteers were amongst the first to arrive, and have been in the midst of the response ever since.

They and MapAction’s other field teams have produced a huge range of maps and data, many of which can be seen at https://maps.mapaction.org/event/irma-easterncaribbean

MapAction reinforcing Hurricane Irma response, sending teams to Haiti, Jamaica & Antigua.

MapAction moved quickly on Wednesday to send additional support to the Caribbean region, following the devastating initial impacts of Hurricane Irma. MapAction is now sending teams to both Jamaica and Haiti in addition to the one that traveled to Barbados on Wednesday morning, which is now moving to Antigua.

Each team consists of two highly skilled Disaster Mapping Experts – specialist technical volunteers – aiming to help make the response to this humanitarian emergency as efficient and effective as possible.

The MapAction teams in Haiti and Jamaica will each link with UNDAC (UN Disaster Assessment & Coordination) who have requested MapAction’s support. Our Teams will arrive very well prepared as MapAction assisted in both Haiti and Jamaica in the response to Hurricane Matthew in 2016, and has kept relevant geographical data updated since then.

The National Hurricane Center has called Hurricane Irma the strongest ever recorded in the Atlantic Ocean. The impact of Irma on Barbuda and St Martin was described as catastrophic, raising fears for other countries in Irma’s path. MapAction now has six volunteers in the field and is monitoring the situation to see further mapping support is required.
