As a researcher acting in rural communities, mobil phone is, for me, very usefull in the planning process of research activities. It allow researchers to get in touch with the differents partners in a very short period of time and at a low cost. It also allows to reach a larger number of people.It also allows researchers to better coordinate their activities and an efficient use of the resources. Mobil telephony is a usefull tool in narrowing the gap between farmers, developpers, extentionists and researchers. Thus it helps in technology transfer and feedback, information dessimination and the market situation. In sum, this technology allows to go faster and produce cheaper.
