Extension services in agriculture are essential in the dissemination of critical information and sustainable agricultural techniques to farmers in Africa. Nevertheless, such services tend to be limited by their reach, language constraints, and lack of context-specific information. With the potential to generate new and context-specific content, Generative Artificial Intelligence (AI) offers a revolutionary means to overcome these constraints and improve agricultural knowledge transfer. This paper investigates the future of Generative AI, with components including Natural Language Processing (NLP), content generation (text, picture, audio, video), context-specific information delivery to individuals, and AI-driven chatbots in reshaping African agricultural extension. We survey applications of AI worldwide in agriculture with examples of success stories along with drawing inferences applicable to Africa. We examine the possible applications of Generative AI in the development of localized recommendations, generating study materials in local regions in local languages, virtual extension agents, and peer-to-peer learning. We also critically analyze the challenges and constraints in the use of AI in African agriculture in terms of infrastructural constraints, digital illiteracy, data availability and affordability of technology. Taking into consideration applicable theories like Technology Acceptance Model (TAM), Diffusion of Innovations Theory, and Social Cognitive Theory, we evaluate factors that affect the adoption and effects of using Generative AI in the agricultural sector. Lastly, we address issues related to ethics and the public and put forth future conduct of studies. We conclude that while there is significant potential in the use of Generative AI, its success depends on due consideration of Africa's particular agricultural context.
