Technologies underpinning smart agriculture include IoT (Internet of Things) devices, drone technology, and data analytics. IoT sensors can monitor crops, soil conditions, and weather patterns, providing farmers with real-time data for precision farming. Drones capture aerial images to assess crop health and optimize resource use, enhancing efficiency. Additionally, big data analytics helps in forecasting trends and making informed decisions about planting and harvesting. These technologies lead to improved yield, reduced waste, and sustainable practices, ultimately contributing to food security and environmental responsibility.
