Addressing issues of agricultural sustainability under irrigated agricultural conditions based on assessment of greenhouse gas emissions intensity, soil and water quality evaluation, resource-use efficiency, and food security.

The Irrigation Efficiency Network is a network of the Croplands Research Group of the Global Research Alliance.

The network may cover changes in management practices including conversion to irrigation, or different irrigation practices and benefits (pivot irrigation, furrow irrigation, sub-surface drip etc.). Different irrigation methods may link to activities in other Networks, for example sub-surface drip irrigation is the most efficient method especially for use with fertigation (application of fertiliser through irrigation) and can reduce N2O emissions when applied as a high number of smaller dose applications. The practice of furrow irrigation requires soils to be tilled and link to conversation agriculture.

The Network could undertake a life-cycle analysis for the various irrigation systems to identify the most appropriate options. Another activity could be information on the best practices for the application of manure and slurry onto fields and the use of liquid manure for fertigation.

The Irrigation Efficiency Network is led by Kevin Bronson, USA. The Network is looking for additional members, particularly irrigation specialists.
