Ramani Huria


Ramani Huria is a community-based mapping project that began in Dar es Salaam, Tanzania, in 2015 training university students and local community members to create highly accurate maps of the most flood-prone areas of the city. As the maps have taken shape – their benefits have multiplied and their potential magnified, now serving as foundational tools for development within all socio-economic spheres beyond flood resilience. The project is supported by funding from the UK Department for International Development through the Tanzania Urban Resilience Programme

We work with community members and students to collect  field information using simple and open tools like ODK Collect and OMK to conduct surveys and produce maps of flood prone areas of the city. 80% of this activity is done by the community members while being assisted by OMDTZ supervisors, through training the community members on data collection by using their own smartphones. Flood data collected include: if the house has experienced flood (Yes/No), if Yes, what was the flood depth, if the person has ever left the home because of floods, which year the flood occured, evacuation centers etc.

Flood Extent Mapping

Flood extent mapping -Mapping areas prone to flooding by assessing flood depth, magnitude and intensity by conducting household surveys. Community members who volunteered to collect were trained on data collection and then conducted surveys at their neighbourhood. 

Drainage mapping

Drainage mapping- Mapping of the type, dimensions and state of the drainage network is an important component and has the potential to establish detailed flood inundation models that can be used to simulate floods at unprecedented scales.

Soil Sampling

Soil Sampling- Ramani Huria partnered with JBA Consulting  (specialized in understanding geomorphological features) all funded by the World Bank and worked on developing a surface soil dataset that will be used for geomorphological assessment and soil characteristics of Dar es Salaam

Trash Mapping

Waste collection in Dar es salaam is a big challenge. Now that population is doubling at unprecedented pace and the effort of waste collection has not being able to match with the increasing population, people tend to dump waste any how i.e in rivers, dams, backyards, drains etc. This mismanagement of waste costs the city dearly.
