The document discusses challenges facing global food production and proposes a solution called Agrosmart. Key challenges include the need to increase food production 70% by 2050 using less resources given problems like water scarcity, climate change, and degraded land. Agrosmart monitors crop fields using various sensors to measure environmental conditions, combines this with satellite data and weather forecasts, and provides farmers online access to real-time data and recommendations. This helps farmers increase yields while reducing water and other inputs in a sustainable way. The system uses a mesh network to transmit sensor data from each field segment to inform tailored recommendations per plot.
