- In the recent past, developing countries have experienced major technological advancements including high mobile phone penetration. With the implementation of innovative technological solutions (e.g. mobile-based systems in key economic activities such as agriculture), there is need to develop models that software developers and researchers can use to design solutions. This paper aims to study the implementation of mobile systems in agriculture and presents a model for designing such applications. This study shows that models exist for general mobile applications design and development, although none specifically suits mobile agriculture applications. A model for designing and implementing M-Agriculture applications is presented. The model concentrates specifically on dairy farming and shows how various stakeholders in this sector can share a mobile platform that meets their various needs.
