Installing a 3D Printing Weather Station in Tandale

Accurate and precise weather information is critical to preparing for extreme weather events, such as flooding. In Tanzania, the weather forecasts are primarily conducted by the Tanzanian Meteorological Agency (TMA) and are available through their website. But, the forecasts are at a regional level, the question is, how can we get an understanding of weather at a local level? Building the weather station As part of the Code for Resilience, supported by the Ramani Huria, the solution to this is being explored, using open source components such as Arduino and equipment that can…Read more

Creating Worldpop Inasafe Integration

Make the world’s population open data more accessible. As part of procedures in preparing better plans and risk reductions against natural disasters, Disaster Managers need accurate population data for the affected area. This helps in many ways from determining the scale of the disaster, impact assessment and analysis to planning for disaster resilience. There are numerous challenges to accurate population data, some national statistics agencies don’t release this openly, some do not have the resources to create accurate population information. Worldpop provides a solution to this challenge, in providing a platform for global…Read more

Mapping Bicycle Routes During Dar es Salaam’s Cycle Caravan

Each year, 5th June marks World Environment Day, a day for raising global awareness to take positive environmental action to protect nature and the planet Earth. This year’s Sunday 5th June saw UWABA (Umma wa Wapanda Baiskeli; or “Public Cycling Community”), a cycling community in Dar es Salaam in cooperation with European Union, organizing the cycle caravan. This is to support low carbon transport, to promote environmental alternatives to high carbon transport as well as putting emphasis on the presence (or absence) of bicycle roads/routes in the city. With the motivation to do…Read more

Participatory Mapping for Historical Flood Inundation Extents

As the neighbourhoods of Ramani Huria have been mapped, it is now possible to start building upon these maps. This can take many forms, but the community is at the heart of how these maps are being used. One approach is participatory mapping, where community members and local government leaders work together to sketch out the extents of historical flood events, drainage systems, ultimately mapping out flood prone areas. By sharing their historical flooding information, it is then possible to more accurately identify at-risk zones and propose temporary evacuation centers. So far, this…Read more

How are the maps being used in the wards?

Guest post by Mercedes Hoffay, Master of Public Administration Candidate - Columbia University All policy students are obsessed with the effectiveness and feasibility of policies and programs that governments implement. So when we find a tool that allows significant efficiency gains in government planning, we are thrilled. That is how we felt when we embarked on our Graduate Capstone Project to evaluate the Humanitarian OpenStreetMap Team’s work in Tanzania and their role in Dar Ramani Huria. Let me introduce ourselves: we are six Masters students from Columbia University, studying Public Administration, International Affairs…Read more

Community discussions on flood prevention at recent Tanzania Red Cross workshop

Ramani Huria was honoured to be part of a recent workshop organised by the Tanzania Red Cross Society as part of their project Zuia Mafuriko (Prevent Flooding). The workshop took place over two days, January 19th-20th 2016, and drew together a variety of stakeholders who play a role in flood prevention in Dar es Salaam. In addition to the Ramani Huria team, participants included members of Community Disaster Preparedness and Response Teams, Kinondoni Municipal council Executive Director, Tanzania Meteorological Agency (TMA), and Ruvu Water Basin Authority. Through the workshop the various stakeholders shared…Read more

How to: JOSM (Java OpenStreetMap Editor)

JOSM (Java OpenStreetMap Editor) is a desktop application to conduct mapping activities, the data from which can be added to OpenStreetMap (OSM). It is an open source editor, written in Java. While initially the interface may seem daunting compared to some other editors, JOSM offers many features which are extremely useful and isn’t too difficult to master. Another major benefit of JOSM is that mapping can be done offline, unlike with other editors such as iD or Potlatch. This has been very useful when mapping Dar es Salaam as our mappers do not…Read more

Community mapping presented to UDSM Masters students

Ramani Huria was excited to be invited by the University of Dar es Salaam (UDSM) to present on digital community mapping to GIS Masters students on 29th of February, 2016. The session was facilitated by Dr. Festus Ndumbaro, university lecturer on Cartography and GeoVisualization. Ramani Huria presented on ‘Web Maps’ and led a discussion with the students, allowing for knowledge transfer between graduated and current students from UDSM. The Ramani Huria team began by giving an overview of community mapping they are facilitating on Dar es Salaam, with the focus on flood resilience.…Read more

How to! A series of blog posts on how to use mapping technology

Ramani Huria uses a range of mapping technologies to collect, process, and share our maps. We strongly believe in the ethos of open source, and when possible endeavour to use these tools in our work. Open source also has the added benefit of allowing anyone who is interested in mapping to learn our processes and either contribute to Ramani Huria or apply it to mapping work elsewhere. In a series of ‘how to’ posts, we’ll be detailing the tools we use and how to use them. The posts will be rolled out over…Read more

How to: Data collection tools

 There are many data collection tools you can use to gather the information required to make maps, depending on your needs and resources. Working in Dar es Salaam, the Ramani Huria team have developed a systematic approach to collect data from a variety of sources and allowing us to develop accurate & sophisticated maps. In this how to blog post, we will give you information about the tools we use specifically to map flood-prone wards of the city and the collection of data for flood resilience. All the data collected with these tools…Read more
