Developing water, energy, and food sustainability performance indicators for agricultural systems

Water use by the agricultural sector along with inefficient irrigation methods and climate change has led to the depletion and insecurity of water resources and consequent instability of the agricultural system. Defining benchmarks and comparing them is essential for sustainable system management performance. The sustainability performance of an agricultural system depends on various factors related to water, energy, and food. This study selects and ranks sustainability performance indicators (SPIs) of agricultural systems with the analytical hierarchy process (AHP). Expert opinions on agricultural sustainability were obtained from Iran's Regional Water Organization. The factors and variables affecting the management of water resources in agricultural systems in a basin area are evaluated with 17 SPIs (10 indicators of water resources sustainability, 3 energy sustainability indicators, and 4 food sustainability indicators) that measure the sustainability of agricultural systems. The AHP reduced the number of indicators to a small number of effective indicators. Results of pairwise comparison and the subsequent determination of the weight of each indicator show that the indicators of water consumption, groundwater level stability, vulnerability of water resources, and water stress have the largest weights (i.e., importance) for agricultural system sustainability at the basin scale. These selected indicators can be applied to agricultural water systems (AWSs).

Automated summary

Water use, inefficient irrigation methods, and climate change have led to depletion and insecurity of water resources, impacting the agricultural system's stability. Sustainable management performance requires defining benchmarks and comparing them, with indicators of water, energy, and food sustainability playing a crucial role. Through the use of Analytical Hierarchy Process (AHP), this study selected and ranked sustainability performance indicators (SPIs) for agricultural systems, with indicators such as water consumption and groundwater stability being identified as key for system sustainability on a basin scale.
