Nigerian Journal of Agricultural Extension

Introduction

The Nigerian Journal of Agricultural Extension is intended to provide a forum for the exchange of ideas and findings in the general area of agricultural extension. Only original scientific contributions relating to agricultural extension will be considered for publication. Because of the multidisciplinary nature of Agricultural extension, contributions from other disciplines with extension implications will also be considered for publication in the Journal.

The scope of Extension Research includes development communication, competence development and performance improvement for a wide variety of fields and audiences, behavioural change, facilitating multiple stakeholder processes, technology transfer,  innovation systems and learning, knowledge/information systems, development extension and processes /approaches/strategies/methodologies, entrepreneur-ship and learning, conflict and decision making, poverty reduction, institutional/group dynamics and project development and evaluation. Most of these can be studied from a multi-disciplinary perspective and will also include all aspects of agriculture including mechanization, irrigation, veterinary, livestock, fisheries, forestry, apiculture, crop protection, horticulture etc; environmental and natural resource management; health and agriculture and sustainable agriculture.
