Starting Ramani Huria – Mapping The Flood Prone Areas In Dar es Salaam

Four years ago, in August 2011 I was fortunate to manage the community mapping of Tandale. It was an experience that irrevocably changed my professional direction and interests. Over a month I trained and worked alongside brilliant students and community members, who were all focused on getting an open map of Tandale, something that had never been accomplished previously. When it was done, the reception across civil society and government was positive and intentions on scaling the pilot to the city were mooted but for one reason or another it never quite made it. Then in December, floods hit the city. In dense informal urban environments such as Tandale these floods are fatal and dramatically change the landscape as well as causing mass damage to survivor’s livelihoods and assets. Mitigating these floods are hard – where do you start in the fastest growing city in Africa? The population as of the 2012 census currently stands of 5 million, with projections showing it could grow to 10 million by 2030.

This rapid and unplanned urbanisation is in part the cause of flooding: the infrastructure with which to cope with high rainfall, such as drains and culverts, were not built alongside residential dwellings. This is especially acute in the unplanned, informal urban settlements where a majority of Dar es Salaam’s residents reside. The theory here is quite simple: If that if you can identify where it floods, you can either install or upgrade infrastructure to ameliorate the situation for residents. Unpacking this, the crux of the issue falls to two main points, governance and data.

Ramani Huria – Swahili for “Open Mapping” – is a operationalization of this theory of change. In March 2015, a coalition from across Tanzanian society, composed of the City Council of Dar es Salaam, the Tanzanian Commission for Science and Technology (COSTECH – under the Ministry of Science, Communication and Technology), the University of Dar es Salaam, Ardhi University, Buni Innovation Hub supported by the Red Cross and World Bank supported the inception of Ramani Huria, with the goal of mapping flood prone areas in Dar es Salaam, making this data openly available and supporting the use of this data into government where decisions can be made to mitigate flooding.

Mapping Phases

Mapping Phases

It is a far cry from 2011 where just mapping the ward of Tandale was a large task. Ramani Huria consists of a pilot phase and four subsequent phases. To pilot, the wards Ndugumbi, Tandale and Mchikichini, with a combined population of over 100,000 residents were mapped in series. This process combined 15 students matched with community members, leading to maps of all features within that community. This information, focusing on drainage and water ways, is critically needed to help understand and locate flood prone areas; this is high priority in Dar es Salaam due to the damage that annual floods wreak upon the city and its residents. In this piloting phase, conducted from March to the end of June these three wards were mapped, in part to generate the data that will generate flood inundation models and exposure layers but also to pilot the data model and gel the team, prior to Phase One.

Phase one on paper is quite simple. Take 150 students from the University of Dar es Salaam’s Department of Geography and Ardhi University’s School of Urban and Regional Planning on industrial training, hold an inception workshop, deploy this contingent across six wards and work with community members to replicate the pilots, but running in parallel. At the time of writing, mapping is ongoing in six communities: Msasani, Keko, Makumbusho, Mabibo, Makurumla and Mburahati. According to the 2012 NBS census, these wards have a combined population of over 280,000 residents. Phase one was kicked off on the 6th of July and will run until the 14th of August.

Phases Two and Three, will integrate community volunteers from the Red Cross, these volunteers are committed to creating community level resilience plans. These plans will use the data produced by the mapping to create resident evacuation routes and aid Ward Exective Officers with planning decisions among many other uses. Additionally, with embedded long term volunteers monitoring change in their wards, this will hopefully result in detailed up-to-date maps in rapidly changing urban areas.

Phase Four unfortunately sees the students depart from the project, due to their graduation. With a remaining contingent of around 30 mappers, mapping will continue until February 2016. These phases cover the data component, consequently alongside these phases are dedicated training events aimed at building capacity to use and deploy this data in real world situations. On the 20th July the first such workshop series took place, with representatives from the Prime Minister’s Office for Disaster Management Department being trained in spatial analysis in QGIS and risk modelling using the QGIS plugin InaSAFE. A series of these workshops will take place, placing the data into the hands of those responsible for the city.

While this is ongoing in Dar es Saalam, you could get involved wherever you are in the world, through the Missing Maps project. Missing Maps is a collaboration between the Red Cross, Doctors Without Borders and Humanitarian OpenStreetMap Team, aimed at digitising “the most vulnerable places in the developing world”, but primarily do so by crowdsourcing the digitisation of aerial imagery. At the moment, there are three tasks for Dar es Salaam:

By helping digitise the buildings and roads, using the recent drone and aerial imagery, the process of mapping is faster, allowing the community mappers to focus on the detail of flood data. Additionally, the data from Ramani Huria is all placed into OpenStreetMap, its code is on Github and content available from Flickr and Facebook, all with an open licence. Please get involved!

Tanzanian Flooding/Start Of The Response

On the 22nd of December heavy rains and flooding hit Dar Es Salaam. Around 20 (that we know have died), leaving many thousands more homeless. This is clearly an issue. Over the short term there are issues with businesses, consumable goods and buildings destroyed. Over a longer term food shortages and public health issues like cholera and typhoid (caused by lack of access to water and clean sanitation) could become apparent.

As such gaining a view of what is going on ‘now’ is important, as this will help organisations like GFDRR and the World Bank among many other institutions make better decisions for the response. Common in disasters and crises has been the Ushahidi tool, however Tanzania has unique qualities which can be exploited in this situation. Step forward Envaya.

Envaya is a non-profit organisation based in the USA and in Tanzania developing and deploying software to aid community based organisations and civil society organisations in developing countries. For the past week or so I’ve been working with Envaya on various projects, importantly a questionnaire which will go out to Envaya’s network of CBO/CSOs to gain situational awareness many factors, including damage and access to water. From this information and data about the damage should then filter from the bottom to the agencies and organisations at the top to aid in their response.

Involvement of Community Organisations

Community Based Organisations Learning About Our Project

Community Based Organisations Learning About Our Project

The first community forum went well. It was deal breaker for the project in the sense that if we didn’t get the community to share our ideals and objectives, making them their own, then the project would fail. Now the map is basically complete for first draft. We have enough of a basemap so we can now support platforms like Ushahidi and enable blogs to be geolocated.

Collecting the data and producing the map, as I’ve previously mentioned is only a first step. The same can be said for involving the students and community members. By creating a small nucleus of highly engaged people, proficient in mapping and storytelling techniques understand the project, they can evangelise the project to others in their community. This ‘infects’ the community from the inside allowing for more people to interact and share the project without ‘outside’ involvement. This will in time hopefully reach a plateau where the entire process of updating the map, reporting and blogging becomes self-sustaining using only the initial equipment and investment.

With this in mind, in the build up to the final community forum of the project (where presentations will be made to the community as a whole ie. interested citizens, civil servants and politicians) we gave a ‘pre-release’ talk to ten community based organisations. The format for this was quite simple, the students introduced the map with it’s features and intended functionality and the community members introduced the storytelling elements.

Within this process I spent most of it being a photographer and an observer. It wasn’t quite seeing the monster you created evolve but when presenting both students and the community are owning the process. The community organisations engaged in a Q&A session then participated in reporting using Ushahidi.

During the Q&A many questions dropped out regarding the future of the project and how the map can be used further. Because we are still formulating the future strategy it is difficult to say what the next step will be, but it will be along the lines of franchising to other areas overseen by community, NGO/CBO and Ground Truth, constructing this framework will be taking place for much of the coming week.

We are also printing the map and distributing it. This is key; in using Open Street Map, the collected data is freely available for viewing and data analysis without restrictions like a prohibitive licence. However accessibility to computers and internet understandably is a problem in communities like Tandale. To enable the community to view their map we will be printing A2 maps for placement in the sub-ward offices and printing A4 sub-ward handouts.

By placing it in a communal areas for each of the communities, we aim to reduce the barrier of people using the map by making it accessible. This process has started with our small nucleus of students and community, expanded by involving community based organisations and will be expanded further by integrating the map into governmental offices at the sub-ward level. Having the map built into the fabric of the community from the beginning of the project should make further incremental additions easier.

Community organisations being fully involved in the project is the next step, the process has been started and the ball is rolling. However Eid is coming in the next week, so everything is going pole pole, Swahili for slowly slowly. However tangible results are starting to become very clear, on all levels with all stakeholders.

Water, Sanitation and Geography

I have been surprised with during the Tandale project with how community members are familiar with the geographic boundaries and extent of their community. On touring areas with community members, it was clear how they used geographic features to navigate. Also the administrative boundaries were formed through natural features like rivers, without being imposed upon by an outside force.

Previously when facilitating mapping (essentially “There isn’t anything here, go have a look”) the mappers would have a difficultly in collating the map and their own mental model. Here in Tandale reading of seemed to be a lot easier than when I have previously experienced.

Map reading is a difficult skill, essentially it starts with understanding that the map is an abstract representation of space. As a map is a representation of space; a visualisation of various elements is at the whim of the cartographer (in our case the esteemed people which write the map styles for OSM) and the data that the cartographer/surveyor collects.

The people of Tandale seem to have a spatial awareness down to a very precise art, using landmarks and features with which to demarcate areas. This also relates to official and unofficial landuse within Tandale. Because of the lack of formal solid waste collection, most of the waste is dumped in swampland or wasteland. Unfortunately these waste areas have no buffer with residential homes, further illustrating the potential for disease.

On a tour of the Sokoni sub-ward executive he spoke at length on sanitation and water security. The conversation turned to common diseases and illnesses within Tandale with Malaria and HIV unsurprising common. Also mentioned in the same breath was Typhoid and Cholera, which, according to the officer,  outbreaks are common. Looking at the state of sanitation and drainage this is very believable.

We believe that the first step to solving these problems is to have a map. Hopefully have enough data to give evidence of the problems, to both inside and outside the community. We have also mapped dumping grounds, formal and informal medical facilities, toilets, water points among many other things. Using the map as a basemap in Ushahidi instance allows for the community members to use the map that they have created. Now our focus turns to completing the feedback loop, so there is an interface for the reports. Funnily enough that’s where my PhD comes in…

Ownership Of Community Reported Problems In Tandale

Within the project we have effectively split into two groups along the lines of students and community members. The students are effectively bug hunting, filling in missed tracks and POIs. The community members are focusing on the submission of data into the Ushahidi instance,

Today was quite special in that the Sokoni sub-ward officer joined one of our community teams, reporting the problems within the community. They engaged fully in the process, finally seeing the problems they had found on the map.

I could feel the sense of achievement from the community members and students. The community members were animated at showing their work to the representatives of the local government, especially those who were on friendly terms with the officials.

Initially I feared that the dynamic of student and community would be one that would be difficult. The students are from Ardhi University and are the best and brightest urban planners that East Africa has the offer (the students come from Zambia, Kenya, Rwanda and Congo). They are on average technology literate and have, with some guidance, become power-users of JOSM and other OSM tools. Understandably the community took time getting to grips with the software and methodology.

We ran a Saturday session, now they are quite proficient with computers, GPS’ and cameras. Closing the gulf the community can help the students and vice-versa. Because we wish for the project to be sustainable the drive must come from the community members, and it has. They’ve really taken ownership of the project. Before they would be querying the OSM Tags, or how to pull tracks and waypoints off a GPS. Now they navigate all tasks with ease.

We start each mapping session at 0900 sharp. To be ready for this time, we arrive at 0830 to set the projector, plug laptops etc. Now I set the projector up, once I’ve handed out the laptops. Nearly all members (community and student) are present, ready and waiting. They, and by extension, Tandale, now own the project.

Ramani Tandale: Work In Progress

Tandale as of the 19th of August 2011

Two weeks or so ago I posted about the impending Map Tandale project. In it I spoke about the broad aims of the project and the methodology. It was accompanied by an almost blank slate; the map below. This is compared with the map above taken on the 19th of August 2011.

Tandale as of the 9th of August 2011

Quite a lot of progress here! One thing that should be considered is the schedule upto this point. We held the community forum on Tuesday 9th of August. Wednesday was about the community and students working together and getting familiarity with the GPS;mapping with your feet. Thursday and Friday downloading GPS tracks and editing with JOSM was covered. Because of enthusiastic community members and students we ran an additional session on Saturday, attended by a few, to further explore the editing process.

This meant on Monday we could really get started with mapping with everyone at the same skill level, and we did. I now think we’ve got around 90-95% of the major tracks done, the rest of the tracks should be finished on Monday/Tuesday. POIs like water tanks and toilets are in, again we have some areas that need to be mapped and these will be picked up by Tuesday.

Community Members Using Ushahidi

Because of us nearing completion we’ve entered phase two of the project; using the map we’ve created to tell stories and highlight issues. To do this we’re using Ushahidi, categorising reports and issues along Water, Health,  Education, Accessibility and Security. These themes were identified, not through previous experience, but from community members themselves.

In the community forum they provided areas where they believe improvement is needed. With us delivering on a system that monitors what they want monitoring we hope to give the community ownership of the project. Once the taxonomy exists within Ushahidi we requested that the community enter some of the issues that they face along the identified themes. After familiarity with the system was gained they then went out into their sub-wards, their communities, and gathered stories and issues that were happening then. The website for the Ushahidi instance is, please do have a look at it, though you will probably have to translate the reports!

One point of note is the name of the project; also chosen by the community. Ramani is Swahili for map. Ramani Tanzania, Map Tanzania. I believe that the community really feel part of something and are anxious to contribute further.

Understandably this is only the first step, realistically we are barely two weeks into the project, however it is shaping up well. In the coming weeks we will focus on using the map to tell the stories and issues in Tandale and looking how the project can become sustainable with a tangible benefit.

So far the tangible benefits encompasses the urban planning students who have gained surveying knowledge and the community members who have improved their own skills with technology, however we want the project to succeed and be a continuing success. To do this involvement needs to occur between Community Based Organisations, Non-Governmental Organisations, Charities and the City Council. We have already engaged these actors on varying levels but will ramp up interaction in the coming weeks.

As a parting note I would like to personally thank Lucy Fondo and Hassan Abdalla from Map Kibera. They engaged the community members and students with equal aplomb and along with Simon Kokoyo, from Map Mathare, smoothed the implementation of the project removing obstacles like language, making it child’s play.

Community Spirit and Toilets

In Kibera and Mathare a community spirit exists however it still feels like every man/woman for themselves. When speaking to some residents they give the impression that this arrangement is temporary. In Tandale the spirit and feeling is very different. The sense of community is strong, as is the level of community engagement in projects apart from ours.

You can see the community cohesion within the structure of the family unit and within residential buildings. On walking through the sub-wards of Pakatcha and Mharitan seemingly most of the houses are arranged in a quad, with a private inner courtyard for toilets and washing facilities.

This has impacted our ability to map toilets (useful for understanding the sanitation issues and requirements) due to problems of access. In this engaging the community through other means, like Ushahidi becomes important.

Next week we will be holding mini-forums with community based organisations and members of the community to pinpoint issues like access to sanitation. Because of how the community is orientated towards working together, we hope we can gather data that would be representative of the community as a whole.  We plan to have a discussion with the community, with students using tools like JOSM and Ushahidi to submit issues while the discussions are ongoing.

With this we start to use the map that we have created to further identity community issues and problems. We are speaking to the city council of Dar Es Salaam, at the moment they like this idea of using this information system to identity problems. By introducing it to the community we hope they will like it too.
