A method for securely managing Internet of Things (IoT)-based agriculture system is proposed. Smart farm management has complex challenges and there is need to improve the overall adaptability, profitability, and environmental soundness of the farming systems. The agricultural production can be enhanced with the help of the IoT-based game tools. The Smart and Secure IoT agriculture system with game scheme is proposed to augment productivity and in the interim mitigating production cost and miniaturizing environmental concussion. These methods have the potential to provide alternative and optimal land use practices for sustainable economic development. The proposed scheme would help in analyzing and examining economic and financial efficiency of optimal land usage. Our gamification model has the potential to provide substantial and optimal game practices for sustainable development. Mean Field Game is proposed to validate the intuitive strategic actions taken by each farm to hold on to safe state zone. This paper relates to an interactive sanitization method and system for mitigating prognostic reverberation of virus exposure using artificial intelligence (AI) and machine learning (ML).
