Facing a 9.7B population by 2050, agriculture is being reshaped by precision farming, AI/ML, IoT, and blockchain to raise yields, cut costs and water use, reduce chemical dependence, and ensure transparent, safer supply chains; real-world rollouts (autonomous tractors, AI insights, blockchain markets) prove impact, while vertical farms, livestock wearables, and farm-to-table tech point to a more sustainable, higher-output food system.
