Crop Water Productivity, Applied Water Productivity and Economic Decision Making

Increasing productive water use in agriculture is seen as paramount to meet future food demand with limited supplies. The main objective of this paper gain a better understanding the interrelated linkages between crop productivity (CWP) and applied (AWP) affected by irrigation management decisions order assess impact economic decision making on CWP AWP under area-limiting water-limiting conditions. A daily soil balance mathematical programming model that explicitly models technology choice stochastic weather efficiency was used study interactions. assumption made rational maker will allocate maximize expected profits. results showed is, large extent, unresponsive increasing applications, especially when applications are approaching maximum potential yields. difference optimal yields for scenarios small, which shows portion production function relevant small falls within range changes. Profit maximizing makers not try or since these objectives result profit losses.
