PARTICIPATORY  THREE-DIMENSIONAL MODELLING
Step by step photo-reporting of P3DM  exercise and training organised by CTA & MELCA It Takes a Village
“ Promotion of Collaborative Spatial Information Management and Communication  in East and Southern Africa”
Telecho, Oromia  Ethiopia - 2010
A P3DM process should happen only where there is previous groundwork done at community level
From a base map the contour lines are scaled up to 1:10.000 m In practice
The contour lines are traced
On carton boards of 3mm, previously cut to size
The carton boards are cropped
Glued and nailed together
And layer after layer of carton board
The slope of the 3D model builds up
And it becomes possible to identify specific features from a birds-eye view
Meanwhile, the elders were invited to discuss the map legend eliciting local knowledge
A clear and detailed legend preparation is crucial for the success of the P3DM process
When the construction phase is completed
The achievement of the group is celebrated
The trainees, the local students and facilitators,  everyone participates
The model is then covered with soft white paper
To smooth the slope and prepare the model for painting
After three days of work the “blank” model is ready
The next day the first group of villagers arrives and has a first contact with the 3D model
From the water lines villagers start to depict  features on the model
Land use and position of different points and lines are discussed and decided, per region
And each group, coming from a different region, gives orientation to next group
Each group, from the 28 participating villages, must understand the legend
P3DM grants the time and space for interaction
P3DM is a process of continuous knowledge sharing
It creates a platform for knowledge sharing,  among and across generations
Interaction and knowledge exchange promote social learning
The P3DM process results in a celebration of community-based action
Where the value of local knowledge is recognised
Then this accumulated knowledge can be  geo-referenced
And the model finally photographed to be translated to GIS
P3DM can be coupled with other tools for promoting participatory action learning
Such as, the Democracy Wall that elicits reflection and sharing of ideas
The Ecological Calendar that enriches the understanding of local livelihood dynamics
And, the Participatory Video for capacity building  in communication
To give power to the voice of participants and to broaden knowledge exchange
The final 3D model of the Foata Mountain Range took 10 days and the work of 130 villagers, 14 students and 20 trainees
It started from a 2 dimensional map
It used 3 mm carton boards, glue, nails, paint
Pins, wool thread, and/or any other possible materials
And it created a platform for people to meet, interact
Learn, discuss, decide and take action
The community built a 3D model of their landscape
Reflected on the past, present and future
And new perspectives for future resource management spontaneously rose
P3DM is much more than the finished physical model
P3DM promotes social learning and collaborative management
 
In the inauguration day
National, regional and local, government and non-governmental, actors were present
As well as the local community members and participants
The P3DM model was presented to the public
