Abstract
The Internet of Things (IoT) is an important technology that provides efficient and dependable solutions in a variety of domains, such as smart agriculture and climatic change. It integrates billions of smart devices that can communicate with one another and gives solutions to automatically maintain and monitor smart agricultural and environmental fields. The combination of IoT, Artificial Intelligence (AI), and blockchain technology will allow us to transform smart agriculture into the Internet of smart agriculture, providing greater control, management, and security in supply-chain networks. This paper presents an overview of the technologies in the domains of IoT, Climate-Smart Agriculture (CSA), AI, Machine Learning (ML), and blockchain. In addition, the paper presents several approaches for integrating IoT with CSA data analysis. Both AI and blockchain are adopted for efficient CSA systems. The paper is concerned with the combination of three recent technologies: IoT, ML, and blockchain to serve the CSA applications. The challenges and opportunities of combining these technologies to serve CSA are also discussed in the paper.
