Category 3 – Agriculture innovations systems and sustainable farming 21. E-agriculture Ensure the systematic dissemination of information using ICTs on agriculture, animal husbandry, fisheries, forestry and food, in order to provide ready access to comprehensive, up-to-date and detailed knowledge and information, particularly in rural areas. Public-private partnerships should seek to maximize the use of ICTs as an instrument to improve production (quantity and quality).
