Smart greenhouse farming represents an innovative approach to agriculture in Nigeria, utilizing advanced technologies such as the Internet of Things (IoT), artificial intelligence (AI), and data analytics to optimize crop production within controlled environments. This method offers substantial benefits, including increased productivity, resource efficiency, reduced labor costs, and improved crop quality. By incorporating AI-driven insights and remote sensing, farmers can optimize growing conditions and manage resources effectively. The case study of BabbanGona, a Nigerian agricultural social enterprise, demonstrates the successful application of smart greenhouse farming, leading to significant improvements in productivity and income for smallholder farmers. This approach has contributed to rural development and poverty alleviation. Despite the potential of smart greenhouse farming, several challenges remain, including high initial investment costs, limited access to infrastructure, and a lack of technical skills and awareness among farmers. Addressing these challenges requires targeted solutions such as policy support and incentives, training programs, and investments in infrastructure to facilitate the adoption of smart greenhouse technologies. Future directions for smart greenhouse farming in Nigeria include integrating climate-smart practices, exploring blockchain technology for supply chain transparency, and developing tailored climate modeling tools. By overcoming current challenges and promoting innovation, smart greenhouse farming can play a pivotal role in achieving food security, economic development, and sustainability for Nigeria's agricultural sector.
