Farmers The front-line worker needs the additional support that comes from national level exposure of the project's objec- tives; but the farmers still need the direct dialogue with you to receive precise information and a demonstration of procedures-and to get your answers to their questions. All the "pressure points" we have discussed can be seen as either positive or negative forces, which will have their influence on a farmer's attitude to adopting your recommendations. The negative ones are the kinds of blockage which were represented by the squiggly line in the communication model presented in the first chapter. Some of the pressure points, like media messages, are external factors; some, like the concern about risk-taking, are in the head. Only when you are familiar with the range and effects of these pressure points can you begin to achieve a rapport with your farmers, which will enable you to work with them to promote change. THE ADOPTION CURVE This analysis of "pressure points" may help us to understand more clearly the way in which farmers-or any group of people-accept or reject new ideas and practices. It seems there is a common and recurring pattern involving five stages: 1. Awareness when a person is first exposed to a new idea-by, maybe, reading a publicity leaflet or talking with a friend. 2. Interest when he relates the idea to his own situation and his curiosity is aroused about its potential bene- fits. 3. Evaluation when he begins to ask questions of himself, his neighbours or the extension worker; when he will be mindful of the potential risks and influenced by both the positive and the negative forces or "pressure points". 4. Trial when he shows his willingness to experiment with the idea on a small scale. 5. Adoption when he takes on the idea into his regular farm practice and begins to argue its merits to other people.
