The ‘Digital Revolution’ is transforming farming. Rapid advances are being made with initiatives such as ‘more crop per drop’, and ‘farm to fork’. The approach in all such initiatives has been based on using smart, connected technologies with intelligent analytics for monitoring, visibility, planning, consumable optimisation, yield maximisation, and supply-chain loss minimisation. Technologies that enable quick, and easy verification of authentication of high-value certifications such as “organic”, are growing in demand. Ability to ‘trace the origin’ of an agricultural product from any time, anywhere is becoming an expectation. Combination of these technologies is also being referred to as ‘Farming 4.0”. For an EE, all of these are applications of IoT in Agriculture. It is an active area of research internationally, and a tutorial on this topic is most appropriate contemporary topic The productivity, and earnings of farmers in India is amongst the lowest in the world. This is despite India being ‘number one’ producer of a number of food items. 30-50% of food is wasted in the Supply-Chain. Cold-chain, appropriate storage, and other loss prevention techniques can minimise losses.
