A study determined the use of different information sources for decision making used by traditional Arab farmers in Israel. A questionnaire was used to interview 48 farmers from 4 villages in the Nazareth region and 56 farmers from 5 villages in the Gaza strip in their homes. Farmers were asked to name major innovations they had adopted during the last 5 years and then to reconstruct their decision-making process, emphasizing sources of information and influence. Sixty-five percent of farmers in the Nazareth region and 58 percent in the Gaza strip reported that they had adopted at least one major innovation, such as mechanization, drip irrigation, new crops, or plastic covering, in the past 5 years. Extension advisers and other farmers were about equal in their importance as the first source of information about the innovation. In the Gaza strip, still the more traditional of the two regions, the extended family was one of the major sources of initial information. In making the final decision to adopt an innovation, advisers had a very strong influence and the family was less influencial in the Nazareth Region. In the Gaza Strip, where advisers have statutory powers and more contact with farmers, their influence was still strong but the influence of family was more dominant. Farmers were happy with their adoption decisions; 98 percent in the Nazareth region and 86 percent in the Gaza strip said that they would make the same decision again.
