This document discusses e-agriculture solutions and technologies that can help address challenges in agriculture, such as an aging society, lack of farm laborers, climate variability, and the need for higher production quality and lower costs. It presents technological approaches for smart officers, smart farmers, and smart farms that utilize ICT, sensors, and embedded technologies. These include a new design for smarter tropical greenhouses, new farm and orchard management systems, approaches for rice and field crop production, and technologies for production quality reduction and knowledge engineering. It also discusses policy-level planning and strategies as well as example technologies and solutions like a farm and farmer registration system, a water optimization model, an early warning system using image processing, and agricultural information services
