The Information and Communication Technologies in Agriculture, Food and Environment themed issue focuses on the potential role and impact of Information and Communication Technologies (ICT) on Agriculture, Food and Environment. Papers presented in this special issue were originally presented in the 5th International Conference held in September 8-11, 2011, Skiathos Island, Greece. The conference was organized by the Hellenic Association of ICT in Agriculture, Food and the Environment (HAICTA) member of the European Federation for Information Technology in Agriculture, Food and the Environment. In the agricultural sector (including food and environment), in contrast to other sectors, adoption rates and general uptake of ICT-based applications have been rather slow and low despite the well documented potential benefits. The papers in this special issue are applied research papers which demonstrate ICT's relevance for the sector.
