“…The project used 2017 data for the Upper, Medium, and Lower Jaguaribe sub-basins, made available in the study of indicators published by ADECE [12]. The data of agricultural production in the sub-basins were obtained by performing a complete register of water users and using the Irrigator Advisory System (Sistema de Assessoramento ao Irrigante-S@I) [31]. The data of agricultural production in the sub-basins were surveyed from farmers, producer associations, irrigation districts, Ceará State Technical Assistance and Rural Extension Company (Empresa de Assistência Técnica e Extensão Rural do Ceará-EMATERCE) and registrations of users of the Ceará State Water Resources Management Company (Companhia de Gestão dos Recursos Hídricos do Ceará-COGERH).…”

The information allowed the preparation of a complete register, entered according to the needs of the computer tool used: Sistema de Assessoramento ao Irrigante-S@I [31]. Weather information was provided by the Ceará State Foundation for Meteorology and Water Resources (FUNCEME), with data from the automatic stations monitored in the basins [27].…”

“…The data used to calculate ET 0 in each of the sub-basins were obtained from eight weather stations belonging to the National Institute of Meteorology (Instituto Nacional de Meteorologia-INMET), located in the study region. The S@I system [31] was the Decision Support System used to determine the ET c in the municipalities of each sub-basin.…”

Performance evaluation of irrigated agriculture is an important tool that assists in decision-making on water management in the river basin, particularly in tropical semiarid regions. This study was carried out using information from the Jaguaribe River basin, located in the Northeast region of Brazil, which has an important restriction in the availability of water resources and high competition for water use. From a set of indicators (production, water, economic, and social), the overall performance index of irrigated agriculture was estimated (ranging from zero to 1.0) for two scenarios: high water scarcity and low water scarcity. The performance index used was based on the mean value of these security criteria normalized with respect to the maximum value of the indicator for the crop obtained in the sub-basin. A low performance index of irrigated agriculture (less than 0.3) has always been associated with inadequacy of more than one security indicator. Crops with significant cultivated areas and, therefore, requiring a high volume of irrigation, such as rice, sugar cane, banana, and green coconut, require technical interventions related to the management of the soil–water–plant system aiming at improving yield with less water. Under conditions of water restrictions, crops with performance indexes higher than 0.3 should be prioritized. The study presented here for Jaguaribe River basin may support public policies related to irrigation and agronomic techniques necessary to improve the performance of agricultural under tropical dry lands.

ResumenUn Servicio de Asesoramiento al regante (SAR) tiene como objetivo principal la optimización del uso del agua en la agricultura, dando respuesta a las demandas tecnológicas de los regantes. El objetivo del trabajo es evaluar la implantación y los beneficios de un modelo de SAR en Brasil, planteado para ofrecer una programación individualizada de riego en parcela a cada uno de los usuarios, basado en el uso de la herramienta on-line "Web S@I". La herramienta incluye en su base de datos una parte fija con información relativa a cada parcela (características del suelo, cultivo, caracterización del sistema de riego, etc ) y otra dinámica que incorpora, tanto la información obtenida de las estaciones agrometeorológicas en la zona que permite calcular la Evapotranspiración de referencia (ETo) diaria utilizando el método de Penman-Monteith, como los valores de los coeficientes de cultivo (Kc), obtenidos en base al seguimiento en campo de lso técnicos. Las encuestas indican que el 31% de los agricultores siguen la información que se les facilita y que la productividad del agua (WP) aumenta en los usuarios del sistema S@I mejorando la gestión del agua en el Distrito de riego DIBAU. IntroducciónLa eficiencia técnica de riego, que es la forma de hacer las mismas cosas, pero usando poca agua, es el preferido por los tomadores de decisiones, sobre el problema de la escasez de agua. Para evaluar el efecto de la eficiencia técnica en una sociedad dada, requiere un debate sobre la productividad del agua, que se puede expresar como agua de uso agrícola por unidad de volumen (Playan; Mateos, 2006).Playán y Mateos (2006) encontraron que, en grandes y antiguos distritos de riego en España, se alentó a las técnicas de gestión para reducir el consumo excesivo de agua de determinados cultivos; Como resultado, se lograron ahorros considerables en agua, con casi los mismos rendimientos de los cultivos. Esto sólo con la orientación y la reeducación de los agricultores.Un Servicio de Asesoramiento al regante (SAR) tiene como objetivo principal la optimización del uso del agua en la agricultura, dando respuesta a las demandas
