A Model for Estimating Premiums to Reduce Irrigation on Farms

Abstract

This paper aims to determine the minimum agri-environmental premium per hectare that farmers should receive to reduce crop irrigation.To this end, the authors develop a mixed-integer quadratic model using a new methodology based on traditional positive mathematical programming, which allows the inclusion in the model of crop variants that are not present in the baseline situation of the farms.What is shown is that the results obtained with this new methodology, using the cost average approach of calibration, are the same as those obtained with an empirical * Corresponding author.

Implications of current and alternative water allocation policies in the Bow River Sub Basin of Southern Alberta

“…However, over the past decade, another set of European studies has made further improvement to the standard PMP calibration technique of Howitt (1995bHowitt ( , 2005 adopted in the computational models used for water allocation issues in Southern Alberta (Paris and Arfini, 2000;Röhm and Dabbert, 2003;Iglesias and Blanco, 2008;Blanco et al, 2008;Cortignani and Severini, 2009;Judez et al, 2011). These improvements centered around a couple of stylized weaknesses of the Howitt's standard PMP calibration technique.…”
