Information technology (IT) is the application of computers and telecommunications equipment to store, retrieve, transmit and manipulate data and has been a key factor in contributing to economic and political change across the world.
Access to information has become both an equalizer and a mobilizer in the effort to meet the challenge of climate change and global sustainability. A new global platform for collaboration has been enabled by the creation of blogs and social networks, giving rise to virtual communities, and a global dialogue that has changed the flow of information gathering, innovation and political mobilization. Permaculture has now developed associations in many countries, linked together by regional institutes, with regular newsletters and meetings. By using the Internet as a communication and information tool it has become possible to share permaculture projects, the variables of experiments, and raw data can be evaluated (and shared) more efficiently.
