This publication contains twelve modules which cover a selection of major reform measures in agricultural extension being promulgated and implemented internationally, such as linking farmers to markets, making advisory services more demand-driven, promoting pluralistic advisory systems, and enhancing the role of advisory services within agricultural innovation systems. The reform issues consider the changing roles of the various public, private and non-governmental providers, and highlights the collaboration required to create synergies for more efficient and effective high quality services responding to the needs and demands of smallholder farmers. The modules draw on reform experiences worldwide and provide an introduction, definitions and a discussion for each specific reform measure, as well as case studies, tools, exercises and a reference list. The reform topics are envisaged for policy-makers, management and senior staff of institutions providing agricultural and rural advisory services. It can also be very useful for students studying agriculture, rural development, and extension in particular. This is a substantially updated version of the 2009 publication of the same title, but with only nine modules. These nine modules were restructured and up-dated, and three modules were added. The layout of the modules changed to allow a better overview for the reader.
