Thank you for your good question. Personally I think broadcasters/journalist are intermediary of information. Here I mean that, you take information from the source i.e. Weather reports, online services etc then you process it to something that will benefit your audience. Here is the role played by the journalist in Beep-4-weather service, Rotilinde (broadcaster/journalist) used to gather Weather Forecasts from different sources. We used different sources so as to improve the predictability of the forecast. So Rotilinde would use online services such as Weather Channel, Toto Agriculture and compare the forecasts from all and information provided by Tanzania Meteorological Agency (TMA) to come up with a forecast that farmers can understand. In both of these reports as you can see you will find that they are presented in scientific format. So Rotilinde would have to translate them into something that farmers can understand. For example, instead of saying 32 degrees of centigrate, she would say it will be very hot in this region. Or instead of 11 mm of Rain, she would say you will experience shower in this region.
After having this piece done, then Rotilinde (broadcaster/journalist), will do an interview with an expert to advice farmers about this forecast. What does this forecast mean to farming activities. Then she would put together and edit the whole content and produce a three minutes audio piece which is a complete weather information suitable for her audience in this case farmers. We also used to share this audio piece with the radio stations, so that they can use them in their farmers programs.
So @IMaiga I think you have all the skills needed i.e. Broadcasting Skills as well as Journalism. You have sources for the information too, there is a lot of online tools there but for accountability I think it is better to involve the local sources.
