PARTICIPATORY  THREE-DIMENSIONAL MODELLING
Photo report of a P3DM  exercise and training organised by CTA & MELCA  Ethiopia, December 2010 It Takes a Village
“ Promotion of Collaborative Spatial Information Management and Communication  in East and Southern Africa”
Telecho, Oromyia  Ethiopia - 2010
 
Here, in Oromyia, Ethiopia, livelihoods are mainly dependent on agriculture
Deforestation is increasingly  becoming a problem
And signs of severe soil erosion and land degradation are evident
In this context  CTA and MELCA organised this PGIS/P3DM/PV exercise, to support local communities and train development pr...
A P3DM process should happen only where the groundwork has been done at community level IMPORTANT
From a base map the contour lines are scaled up to 1:10.000 m IN PRACTICE
The contour lines are then traced…
…  on card sheets of 3mm,  which have been cut to size
The card sheets are cropped…
…  glued and nailed together
Then layer after layer of card are used…
…  to create the slope of the 3D model
Slowly 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
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 in the celebrations!
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 its first contact with the 3D model
From the water courses villagers start to identify features on the model
Location of areas, points and lines are discussed and agreed upon
Each group, coming from a different locations, provides guidance to the next group
Each group, from the 28 participating villages, needs to fully understand the legend
P3DM allows time and space for interaction
It 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
The model becomes the repository of geo-referenced information documenting local knowledge
The data on the model are extracted using digital photography for import into a GIS
P3DM was coupled with other tools for promoting participatory learning and action
Such as the ‘Democracy Wall’ which elicits  reflection and sharing of ideas
The process included ‘Participatory Video’ for building capacity in communication © Giacomo Rambaldi
And to add power to local voices and broaden knowledge exchange
On the top of several months of preparation, it took 10 days to manufacture the model and inputs from 130 villagers, 14 st...
The manufacture of the model started from a planimetric map…
We used 3 mm carton boards, glue, nails, paint
Pins, wool thread, and other materials
And this created a platform for people  to meet, interact…
Learn, discuss, decide and take action
The community built a 3D model of their  bio-physical and cultural landscapes,
Reflected on past, present and future,
... and on new perspectives for future resource management
While practicing P3DM what counts the most is the process rather than the output
P3DM promotes social learning and stimulates community-based initiatives
 
Inauguration Day
National, regional and local, government and non-government actors attended the event
Together with local communities
The P3DM model was unveiled ...
Presented by local villagers ...
