Abstract

There are several constraints to the adoption of technologies and innovations by Australian farmers. Here an attempt has been made to define the major constraints to adoption. These are identified as: the extent to which the farmer finds the new technology complex and difficult to comprehend; how readily observable the outcomes of an adoption are; its financial cost; the farmer's beliefs and opinions towards the technology; the farmer's level of motivation; the farmer's perception of the relevance of the new technology; and the farmer's attitudes towards risk and change. The classical adoption-diffusion model and subsequent modifications are discussed. In particular, issues relating to the participatory action research (PAR) approach are raised and discussed. In addition, methodologies in extension research are briefly discussed and the roles of extension personnel and agricultural scientists in the technology adoption process are examined. The adoption of innovations in natural resource management is discussed and the findings indicate that this is an area of agriculture in which extension practice and research will play an increasingly important role in the future. Recommendations for further research into adoption of technological innovations in resource management and agriculture are made.
