This document discusses the challenges facing global agriculture in the 21st century and how information and communication technologies (ICT) can help address these challenges in a sustainable way. Key points include: - Agricultural productivity dramatically increased in the 20th century but relied heavily on chemicals and resources, threatening sustainability. - Issues for 21st century agriculture include food shortages due to population growth, land and water constraints, and climate change impacts. - ICT can help optimize agriculture through precision applications, cost reduction, robust production, food safety/traceability, and research support. - Challenges include acquiring detailed local data, sharing data/applications globally, and addressing language/literacy barriers for small farmers. -
