Abstract

This paper aims to assess and analyze the payment capacity for bulk water to the producers of the public irrigation districts at Jaguaribe Basin as a whole; for each district located at this basin; for agricultural and cattle raising run as main activity; and, at last, subsidize the State action concerning to making a matrix of water tariff for bulk water to this basin. The study area is the Jaguaribe basin in the State of Ceará. The data are of primary source, gathered by the application of 66 questionnaires. The payment capacity is measured by the residual method. We conclude that the total payment capacity of the producers is R$ 46.57/1000m3. The Icó-Lima Campos public district shows the lowest indicators of payment to water, when compared to other districts. The district of larger payment capacity is Jaguaribe-Apodi (DIJA), whose major exploitation is fruit. A sub set of fruit producers showed higher payment capacity (R$ 103.67/1000m3 ), overcoming in almost three times the sub set of grains and cattle (R$ 34,50/1000m3 ) and grains only (R$ 37.47/1000m3). Some producers showed net income covering the current tariff charged by COGERH, while other did not had payment capacity.
