Brainstorming presentation for mapping of technology adoption using geospatial technologies including remote sensing and spatial modelling in geographic information systems.

1. Where is my technology going?
Mapping of adoption of technologies and
assessing diffusion pathways
using geospatial technologies

6. Project intervention
Smart-valleys:
Participatory low-cost development approach for rice-based
systems in inland valleys that is easy to replicate.
(drainage canals, field bunds, land levelling and where possible
irrigation canals)

Smart-valley demonstration site
Project approach:
Development of demonstration sites and stimulate diffusion and
adoption.
Training field technicians from national partners, extension services
and NGO’s, as well as lead-farmers.
Achievements:
60+ demonstration sites developed in Togo and Benin (2012-13)
100+ field technicians trained
100’s of farmers trained on-the-job
Large-scale adoption observed (2014)

• Farmers expand existing demonstration sites
• Farmers in demonstration sites develop new sites elsewhere
• Farmers develop new sites supervised by trained field officers
• Farmers develop new sites supervised by trained lead-farmers
• Farmers copy the approach and develop sites without project
support
• NGO’s and national agricultural development projects adopt the
approach and develop sites with farmers.

- Can we monitor adoption with geo-spatial techniques?
- Can we map and model the diffusion pathways?
- Can impact surveys be targeted better using geo-spatial
information?

- Can we map and model the diffusion pathways?
• Adoption takes place in inland valleys
• Adoption take place close to
demonstration sites (buffers)
• Adoption requires a road network (travel distances from
extension services)
Spatial analysis & modelling in GIS
Required: detailed inventory of adoption sites
and existing diffusion pathways
Can we map and model the diffusion pathways?
monitor adoption with geo-spatial techniques?
