Technology can be used as a tool for development by building human capabilities. It can enable people to live longer and healthier lives, acquire knowledge, enjoy a decent standard of living, and participate in social, economic, and political life. Technological change can spur economic growth and increases in productivity, freeing up resources that can be invested in health, education, and infrastructure to further development goals. Examples of how technology has been used for development include financial modeling, traffic engineering, intelligent transportation systems using information technology, and nuclear technology for sustainable infrastructure projects.
