Introduction

As urban populations continue to grow and arable land becomes increasingly scarce, innovative agricultural solutions are needed to ensure food security and sustainability. One promising approach is the integration of rooftop greenhouses with artificial intelligence (AI) for efficient crop production in urban environments. This article explores the cutting-edge concept of AI-driven sorghum farming in rooftop greenhouses, examining the technologies, methodologies, and potential impacts of this emerging agricultural paradigm.

Sorghum, a versatile and resilient grain crop, is an ideal candidate for urban rooftop cultivation due to its adaptability to various climates and its nutritional value. By leveraging AI technologies and controlled greenhouse environments, we can optimize sorghum production in ways that were previously unattainable in traditional farming. This approach not only maximizes yield and quality but also contributes to urban food production, reduces transportation costs, and minimizes environmental impact.

1. Rooftop Greenhouse Design for Sorghum Cultivation
