Abstract

Cropping pattern optimization considering uncertainty of water availability and water saving potential

Highlights

Optimization of cropping patterns plays an important role in high-benefit and water-saving agricultural management[1], which determines the water requirement at the head and helps estimate the required capacity of the reservoir and the canal system[2]
This paper focuses on the irrigation water-saving potential, estimating how much water could be saved and reused in an irrigation system through the development of water-saving agriculture in future
After the calculation in this paper, when the water-saving rate increased by 10% and 20%, it would increase to 0.6 and 0.62, which fulfills requirements of water resources planning

Summary

Introduction

Optimization of cropping patterns plays an important role in high-benefit and water-saving agricultural management[1], which determines the water requirement at the head and helps estimate the required capacity of the reservoir and the canal system[2]. Irrigation water is a key determinant of a crop area optimization model[3]. At present time in northwest of China, irrigation efficiency is low, meaning there is higher agriculture water-saving potential[6]. Estimation of irrigation water-saving potential, which can calculate how much water could be saved by adopting water-saving measures, is desired and would benefit agricultural water management[7,8]. Jägermeyr et al.[11] incorporated a process-based irrigation system representation n into a bio-agrosphere model to calculate the water saving potential. Previous literature focused on applying experimental and statistical methods to quantify agricultural water saving potential but relatively little attention was given to the irrigation water-saving potential caused by agricultural water-saving engineering development
