Identifying and evaluating eight extension functions and implications for policy, planning and evaluation

Purpose: This paper reports how different extension roles and their functions – or contributions - were identified within an agricultural innovation system to inform their evaluation. Methodology and findings: This study co-developed eight extension functions and evaluation measures through case studies of teams working to reduce agricultural pollutants entering the World Heritage-listed Great Barrier Reef, off the North East Australian Coast. Practical implications/value: This provides a practical approach for effectively evaluating a range of extension functions in agricultural innovation systems. Theoretical implications: Develops a full set of extension roles, contributions and measures for evaluating impact of several extension functions within agricultural innovation systems.
