A Stochastic Optimization Model for Agricultural Irrigation Water Allocation Based on the Field Water Cycle

Abstract: Agricultural water scarcity is a global problem and this reinforces the need for optimal allocation of irrigation water resources. However, decision makers are challenged by the complexity of fluctuating stream condition and irrigation quota as well as the dynamic changes of the field water cycle process, which make optimal allocation more complex. A two-stage chance-constrained programming model with random parameters in the left- and right-hand sides of constraints considering field water cycle process has b… Show more

“…Devising an accurate mathematical crop evapotranspiration (ET) model is fundamental to improving crop water use efficiency and thus important in developing a practical irrigation system for a greenhouse [ 1 , 2 ]. Evapotranspiration is an important parameter in the study of dynamic change in a field water cycle [ 3 ] and energy balance [ 4 ] and is therefore of great concern in agricultural production.…”

“…This study contributes to the literature by evaluating how weather variations in a changing climate, unknown at the moment that decisions are taken, affect sustainable nutrient management practices. To this purpose, we draw on methods from stochastic optimization, which have recently been applied in the field of agricultural hydrology and irrigation management [21,22]. A small number of stochastic optimization models exist that deal with nutrient pollution, for instance for Lake Balaton in Central Europe and Erhai Lake in China, but these studies do not consider climate change [23,24].…”

“…There is another study by Zehao and Li (2018) in which they expanded a two-stage chance-limited programming approach with accidental variables on both the left and right sides of boundaries for agricultural irrigation water allocation in the district of Yingke, in the centre of the Heihe River basin, north-west China. Their model has the capacity to introduce logical irrigation allocation rules by paying attention to all these aspects: water transformation among crops, evapotranspiration, precipitation, irrigation, soil water content and deep percolation.…”
