             “The farmer-to-farmer exchanges of their personal
             experiences with hybrid seed were at the heart of
             diffusion. When enough such positive experiences
             were accumulated by innovators, and especially by
             early adopters, and exchanged with other farmers
             in the community the rate of adoption took off.
             This threshold for hybrid corn occurred in 1935.
             After that point, it would have been impossible to
             halt its further diffusion.”

                                 So what’s radio got
                                    to do with it?

                                 • Nearly 80% have access to radio
                                 • Farm radio broadcasts have
                                   existed for a long time
                                 • Most of them have failed to

                    –After the staff took a basic radio
                     training workshop, production
                     responsibility was left completely to
                     the radio stations themselves.
                    –Content was supervised for each radio
                     station by a technical advisory
                     committee that included content

    Challenges during the experiment
       led to our own innovations
 • Partner radio stations were not equipped to
   go to rural communities and interview
   farmers. Professional recorders were in short
   supply and very expensive ($400).
 • Solution
     – MP3 players with built-in
       recording capability.
     – Cost $50 each (today down to $35)

When enough such positive experiences were accumulated by innovators, and especially by early adopters, and exchanged with other farmers in the community the rate of adoption took off. This threshold for hybrid corn occurred in 1935. After that point, it would have been impossible to halt its further diffusion.” Everett Rogers, Diffusion of Innovations, 1962 10 Learn More www.farmradio.org info@farmradio.org @farmradio

Editor's Notes

  1. What do we have that binds us? In all communications we look for shared experiences and common bonds. It is one of the most important ways we decide on the value or trust we place in another person. So here we go – In the room I see people I know and who know me and people who I know a bit about but who might not know me. Then there are people who have never heard of me (except maybe through the invitation and introduction). ... So before I start the formal talk, I want to expose a bit of me to you. It might color, I hope in a warm way, how you see me.
  2. Identify social scientists /economists in group. Identify communicators in group. Identify others in group
  3. Everett Rogers is the ‘father’ of modern innovation theory. In 1962 he published the first edition of his work Diffusion of InnovationsRyan and Gross did the first detailed innovation dissemination study (Published in 1942). They looked at how hybrid maize came to be adopted in Iowa in the US, starting from its first introduction in 1928. They looked at the role of the very good extension service and farmer to farmer communications to move the technology
  4. Here is a graph from the original Ryan and Gross publication. It shows in the top curve the cumulative number of adopters over time and below the time differentiated number of adopters – that is new adopters per year. It took more than 10 years (based on interviews of farmers in two communities) for hybrid maize to be completely adopted.
  5. One of the conclusions drawn by Ryan and Gross from their interviews was that the initial adopters in the first years were influenced by extension services but later it was almost entirely farmer to farmer communication from these early adopters to their neighbours that resulted in more acceptance of the new crops. Also they noted that most farmers actually ran their own trial plots before deciding to make the switch. During all of this time – more than 10 years – the extension services remained active.
  6. Here I have plotted just the data, leaving out the ‘normal curve fit’. The data does not actually fit a symmetric bell curve shape very well. Nevertheless, that easier to describe distribution has been used to model dissemination data for a long time.
  7. The work of Ryan and Gross led to modern diffusion theory. The classic model, elucidated by Rogers is this:The social system is important because it provides the channels by which the easiest communication paths are followed. For example in Uganda the church congregation plays a role in seed variety dissemination among families and in Ethiopia CIAT studies showed that kinship lines that moved innovation from village to village but within families was the preferred diffusion pathway. In the original hybrid maize study in the US, Ryan and Gross found that it was neighbour to neighbour, friend to friend. This diffusion takes time because there is often a long gap between first knowledge and adoption. In the Ryan and Gross study, more than half the farmers had heard about Hybrid maize by 1932 but less than 10% had adopted. (5 stages Knowlege->Persuasion->Decision->Implementation->Confirmation)This is not the only model (see Douthwaite, “Enabling Innovation”, 2001) but it is instructive and useful here as it seems to fit much of the kind of centralized innovation work in cropping systems being done by CG centers – albeit now with much more direct farmer participation
  8. The distribution does not have to be “normal” but the curve is useful – though the designation of the last adopters as “laggards” by Rogers is quite pejorative.
  9. Writing about the way diffusion seemed to take place, at least in studies like the one on hybrid corn in Iowa, Rogers talked about a point during the process when if the innovation was valuable, its adoption took off. ... As he said, impossible to stop.I was fascinated when I read this bit of Rogers original book from 1962. The language reminded me of something – something I had seen as a child on TV. Perhaps Rogers had seen it too I wondered if it influenced his thinking.Here are about 40 seconds of the best educational video ever made... By Walt Disney as part of a 1957 TV show (just 5 years before Rogers published his book) called “The Atom is our Friend” (could have been propaganda encouraged by the Eisenhower administration when the “cold war” with the Soviet Union was very tense and atmospheric testing of nuclear devices was common).
  10. For example Malcolm Blackie, working in Uganda, commissioned a radio drama series with an agricultural theme. He concluded based on his observations that program with messages for rural audiences had to be entertaining to be effective.
  11. We did in two cycles, one in each of successive years, many different interventions, all farmer approved
  12. Farmers told us and our radio station partners they wanted the improvement in our formative research using focus groups, key informant interviews and so on.
  13. This schematic shows how we set up our research space. The black circle represents the limit or range of the signal of the radio station. Within the station are many farming communities. Those that received regular visits from the broadcasters for interviews and from the research staff of the project for the collection of data formed the participatory part of our project. We selected two communities in the broadcast area. We also selected two communities – shown here in ret – that could not received the radio signal but were otherwise similar in farming systems, income and so on as the active communities. Here we show one outside the range of the transmitter and the other one behind a hill. This was the state during the period of the participatory radio campaign broadcasts
  14. Some months after the broadcast series was complete we conducted an outcome evaluation – just like Ryan and Gross had done in the 1940s. We surveyed a sample from our participating communities – we call them ALC or Active Listening Communities and from our two control communities. But we also did one other crucial thing. We selected two other communities that had not been involved in any way with our surveys, with radio station visits or interviews. If they had heard about the intervention and its benefits, much of that news would have to come from the radio alone and we could check that because we had the control communities. We called these communities Passive Listening Communities.
  15. Then came the shock. While each of the three graphs above is very interesting, I want to focus on the right hand one. It shows from our survey how many farm families actually decided to try the innovation that had been part of the radio campaign. Not surprisingly, the Active Listening Communities – the ones with regular contact with the radio station, the ones where the participatory research had been done – had significant trial adoption – about 40% of families. The control communities showed little trial adoption. That is good otherwise our experiment would have been a real mess. But look that the red bar... The trial adoption in the Passive Listening communities... It was more than 20% averaged across 15 radio stations and campaigns. Just the radio.... Just 14-16 weeks of radio broadcasts in half hour segments.And we found that those communities had found and listened to the broadcasts, all on their own... To the tune of 66% listening to at least half of the broadcast series in their area.The graph hides a massive truth, the one I showed in the sneak preview. That is we had only two active communities per radio station but maybe hundreds of passive ones – we only surveyed two of them. When you do the math here is what happens for the total broadcast area of the 151 stations in 5 countries.
  16. Depending on what figure you use for average household size, you get up to 6 million beneficiaries in a million households where the innovation was tried. Now there is a caveat... I have no error bars on the PLC data – it was based on a total of 100 interviews in (50 male head of household, 50 female) in the two selected passive communities. But across all five countries and fifteen stations that is 1500 interviews. The data is fairly consistent across the sample (for details and discrepancies, please see our report to the Bill & Melinda Gates Foundation)
  17. We also found a very strong positive correlation between frequency of listening to the broadcasts and trial adoption – across both passive and active listening communities. It appears that the major effect of engagement with the Active Communities was to increase their listening to the broadcasts. What that tells us for the future is that we should get radio stations to make major efforts to increase the audience for the farm program throughout the listening area. That could be done via on-air competitions, visits of station personnel to many more villages to do interviews. Promos that said things like “tonight on the farm show we visit the community of ....”
  18. Top down with experts telling farmers what to do or what the government policy is
  19. We are using the latest survey technology with a mobile phone system called Mobenzi that gives GPS location, a photo of the interview subject and uploads the data automatically.I believe we have created a tool that can make a huge difference to small scale farmers in Africa
