Demand-driven extension services fundamentally have the farmer at its centre. They are farmer-centred, farmer-led, bottom-up and participatory services that focus on what farmers identify as their needs and desires for information, services and support. What does the farmer need from services, what does the farmer want to know, what support does the farmer require? There are three main principles of DDEAS i.e.; Services are based on user demand, Service providers are accountable to users, particularly on content and quality and Users have a choice of service providers. Although conventional supply-driven extension approaches had their utility and advantages in the initial years of agricultural development in India, it has now become outdated. The commercialisation of agriculture and changing climate conditions call for an extension approach that is farmer-centric and can cope with the changing agroecosystem. The demand-driven extension is one such approach that meets with the changing trends in agriculture and has the potential to provide holistically and one-stop solutions to farmers.
