Micro-Irrigation Technology Adoption in the Bekaa Valley of Lebanon: A Behavioural Model

Potato crops are one of the main sources of income for farmers living in the Bekaa Valley of Lebanon. Given the high sensitivity of potatoes to water stress, water shortages can cause considerable losses in terms of potato yield and quality. To overcome this challenge, the use of water-saving technologies such as micro-irrigation systems are very important. However, the adoption of this technique remains quite low among potato farmers in the Bekaa region, who still use ordinary sprinkler systems. In this study, the unified theory of acceptance and use of technology (UTAUT) serves as the conceptual framework for investigating these farmers' behaviour in adopting a new micro-irrigation system. To achieve this objective, we extended the UTAUT model by considering farmers' risk perception of the use of a new micro-irrigation technology. The moderators tested were age, previous experience, voluntariness of use, gross unit margin and educational level. Examining the standard regression coefficients, i.e., the beta weights, the results indicate that performance expectancy raised behavioural intention for investment in micro-irrigation (beta = 0.29) while for effort expectancy the beta weight value was 0.24. Overall, an increase of 1 standard deviation of the behavioural intention strongly impacted investment in micro-irrigation systems, beta = 0.8 standard deviation of the effective adoption of the technology. Risk perception (beta = -0.08) negatively affected farmers' performance expectancy, i.e., the higher the perceived risk, the lower the perceived performance of the investment, which in turn affected their intention to use micro-irrigation systems. Age (beta = 0.11) exerted a significant effect on effort expectancy. Finally in this paper, the policy implications of the results are discussed.
