This research paper explores innovative methods for autonomous Sahara farming using advanced technologies to address pressing global challenges such as food security, climate change, and pollution. Focusing on the integration of smart agriculture applications based on the methods and technology which are used in the 5G Smart Country project in lower saxony in Germany. The study presents a comprehensive approach to transforming desert landscapes into productive agricultural hubs. Key solutions include autonomous farming systems, solar-powered desalination, and IoT-enabled monitoring to optimize water and soil management. By integrating these technologies within the Smart Country Project framework, this paper presents a scalable model that mitigates the impacts of global warming, enhances sustainable food production, reduces pollution, promotes greater climate stability, and strengthens environmental resilience in arid regions.
