The Agricultural Advisory Services Analysis Report assesses the different ways that farmers are given advice and how effective these methods are at achieving behaviour change. It recommends using existing advisory channels, following a tiered approach. This approach starts by capitalising on public services, such as the English Catchment Sensitive Farming Deliver Initiative, then mobilising private and third sector services, for example by working with industry bodies and membership organisations; and finally by supporting independent advisers to deliver this advice.
