“…When developing ICT innovations for farmers in food security, these systems should include a strong focus on improving farmer performance, as this is their primary goal in being included in the food security field. It is also important to note that no amount of ease of use of a technology will replace the level of usefulness of that technology (Keil, Beranek & Konsynski 1995).…”

Background: This study integrates the diffusion of innovation, technology acceptance model and Hofstede’s cultural dimensions theory to assess the role that information and communications technology (ICT) plays in ensuring food security. A survey of smallholder farmers from the iLembe district municipality of the KwaZulu-Natal Province of South Africa was conducted, and the data were used to test the proposed model.Objectives: The study evaluates the influence of ICTs in improving food security in KwaZulu-Natal Province. A theoretical framework was developed as the lens through which diffusion and adoption of ICTs can be understood. The theorised model was developed using constructs from the diffusion of innovation (DOI) theory, technology acceptance model (TAM) and Hofstede’s cultural dimensions theory.Method: Survey data from 517 smallholder farmers from the district municipality of iLembe were collected using a questionnaire. A quantitative approach was followed, and the developed theorised model was analysed using structural equation modelling techniques.Results: This study proposes that ICT influence on food security is associated with culture, perceived usefulness and perceived ease of use. The study further finds that perceived ease of use of ICTs has the most significant effect with regard to ICT adoption and diffusion amongst smallholder farmers in iLembe district municipality. There are, however, no associations found with perceived attributes of innovation and the nature of social systems. The study consisted of a largely homogeneous social system; therefore, the researcher could not make any comparisons.Conclusion: The proposed framework for evaluating the influence of ICTs on food security put forward in this study highlights a number of issues. Firstly, there is need for further study to be conducted to understand adoption of ICTs specifically for food security. This would help in creating more accurate adoption strategies. Secondly, the study informs ICT innovation developers on the need to prioritise ease of use of ICT-based interventions when developing innovations that focus on smallholder farmers. The study also contributes to policy guidelines and suggests clear guidelines be developed to address cultural aspects such as gender imbalances.

“…Le premier est le risque de focaliser la conception et l'évaluation sur l'utilisabilité et de négliger l'utilité (Keil, Beranek & Konsynski, 1995). En effet, même très utilisable, un système a de fortes chances de ne pas être accepté s'il n'est pas utile.…”

“…As mentioned earlier, TAM suggests that PEoU and PU influence intentions to use technology. However, some studies (Keil et al, 1995) show that PEoU may not always directly influence intentions. On the other hand, Cho and Sagynov (2015) investigate the effects of PEoU and perceived usefulness on internet shopping.…”

Abstract. Adoption studies on electronic tax-filing system using data from emerging nations are rare. The present paper studies the influence of perceived ease of use, perceived usefulness, and user satisfaction on taxpayers' behavioral intentions to adopt electronic tax filing services in an emerging economy. For this study, constructs from Theory of Planned Behavior (Ajzen, 1985(Ajzen, , 1991, Technology Acceptance Model (Davis, 1989), and Information System Success Model (DeLone & McLean, 1992) are used. In order to test the impact of perceived ease of use, perceived usefulness, and user satisfaction on behavioral intentions to adopt online tax filing system, we develop several hypotheses. The data is collected from 201 respondents who filed taxes using government or private vendor websites. A structural equation modelling scheme using PLS is used to analyse the model. The measurement model not only shows structural validity but also demonstrates adequate predictive and explanatory quality. A strong support for a majority of hypotheses is found.
