Case studies on the nature, use and availability of extension advice in six irrigation schemes in Tanzania, Mozambique and Zimbabwe are presented. The use of government extension officers varied significantly, with extension use not linked to farm outcomes. The results suggest the need to support more diverse sources of advice and to promote institutional reform in south-eastern Africa.en© 2016 The Author(s).
