How Missed Calls Amplify Farmers' Voices

This week, Farm Radio International (FRI) announced the results of an innovative poll covering thousands of farmers. The biggest surprise was the way farmers voted: by calling a phone number and hanging up.
The survey was conducted in Tanzania, where smallholder farms (small family farms) make up around 75% of all farm production. FRI, an international radio service that partners with local stations, wanted to poll those farmers in order to help make their voices heard by the Tanzanian government. But how do you reach thousands of tiny farms spanning a whole country? In the case of Tanzania, the answer was radio talk shows and basic cell phones.

The Power of Radio Talk Shows and Cell Phones
Across Tanzania, there are radio stations broadcasting talk shows aimed at farmers. Those programs are already popular for the people the survey aimed to reach, so FRI partnered with five radio stations in different regions across the country. The local presenters added discussion segments to their programs dealing with the poll issues.
Radio broadcasters concluded the poll segments by asking yes/no questions, then giving out phone numbers that voters could dial into. But people generally don't want to waste their cell phone minutes on a poll, so a clever solution came into play: just call the number, then hang up. The missed call is logged, and that log constitutes a vote. This system is called "Beep to Vote," and it's free for voters because the missed call doesn't incur charges for using cell phone minutes. For yes/no questions, there was one phone number for "yes" and another for "no." A total of 8,891 smallholder farmers participated.
In addition to the "Beep to Vote" yes/no questions, the poll included a multiple-choice question that most voters responded to using SMS. Voters texted a single character ("1" for the first option, "2" for the second, and so on) to a specified phone number, and those results were tallied by computer. In addition to the SMS voting method, farmers could opt to make a voice call to an automated system, listen to the five options, and press a number to indicate their choice. 4,372 people responded to the multiple-choice question. The system was also able to send SMS reminders to voters in case they voted for one of the poll questions, but not the others.
The data was crunched in realtime using a system made by Telerivet, so poll workers could watch as votes came in. The system also checked incoming phone numbers so each phone (which roughly equates to each voter, or household) could only vote once per question.

Why This Matters
From a technological perspective, this poll is a brilliant example of choosing the right technology for the job. If a similar poll were conducted targeting middle-schoolers in the United States, it's likely that technologies like YouTube videos and click-to-vote within the video would be used. But for these Tanzanian farmers, the prevalent technologies are radio and cell phones. By putting them together, in a near zero-cost way, FRI was able to collect data that could influence government policies, which in turn could change lives—using just cellphones and radio.
This poll was part of a campaign called Do Agric, focused on encouraging African leaders to invest more in agriculture, in order to improve farming (and in turn, daily life) in Africa. Here's a video about the program:
When the results were announced earlier this week, Tanzania's President Kikwete said, "Action on agriculture has to be today, not tomorrow!" The voices of 8,891 farmers reached the president's ears.
