Innovative adoption and diffusion research

October 14, 2014

The number of inland valleys developed using the Smart-valleys participatory approach is rapidly expanding. Around the demonstration sites and in the zones targeted by the SMART-VALLEYS project adoption is witnessed at significant scale. Lead-farmers and trained field technicians provided supervision and technical support to farmers in order inland valleys that have demanded their support. Trained farmers in the demonstration sites frequently leave those sites to be able to developed a larger area elsewhere using the approach.

AfricaRice wishes to understand at which scale adoption takes place and what are the most common and efficient diffusion pathways. Drs Arouna and Zwart, respectively Agricultural Economist and Remote Sensing and GIS specialist, have set up an innovative research to track adoption and map the diffusion pathways. Traditional adoption and diffusion surveys are being implemented backed by a remote sensing analysis of change detection and objected-oriented classification approaches. First results are expected early 2015. The presentation below provides an outline of the approach.
