En un pa\u00eds donde la agricultura es uno de los pilares de la econom\u00eda, la disponibilidad de agua sigue siendo un factor clave para la producci\u00f3n. El impacto del d\u00e9ficit h\u00eddrico 2022-2023 en la producci\u00f3n agropecuaria de secano le gener\u00f3 al pa\u00eds p\u00e9rdidas econ\u00f3micas directas estimadas en 1.000 millones de d\u00f3lares (OPYPA, 2024). El riego permite complementar el aporte de las precipitaciones, asegurando el suministro de agua a los cultivos, lo que mejora los rendimientos y reduce la variabilidad entre a\u00f1os.<\/p>\n\n\n\n

En Uruguay, desde 2019 se ha experimentado un crecimiento continuo del \u00e1rea regada. En la zafra 2023-2024, seg\u00fan datos de Regadores Unidos Uruguay (RUU), se regaron 44.103 hect\u00e1reas de soja y ma\u00edz. La gran mayor\u00eda de los c\u00edrculos de riego se ubican en los departamentos de Soriano, R\u00edo Negro y Colonia.<\/p>\n\n\n\n

El mayor impacto de esta tecnolog\u00eda se observa en los cultivos de verano, ya que su principal limitante ambiental en secano es la disponibilidad h\u00eddrica. La baja capacidad de almacenamiento de agua en los suelos y la dependencia casi exclusiva de las precipitaciones, caracterizadas por su elevada variabilidad, son las principales causas de esta problem\u00e1tica. El riego ha permitido una ganancia promedio de rendimiento del 80% en ma\u00edz y del 40% en soja en los \u00faltimos seis a\u00f1os.<\/p>\n\n\n\n

La brecha de rendimiento entre secano y riego se ampl\u00eda en los a\u00f1os con precipitaciones por debajo del promedio, especialmente en ma\u00edz, debido a su mayor demanda h\u00eddrica. Sin embargo, lo m\u00e1s relevante es la disminuci\u00f3n en la variabilidad de los resultados entre a\u00f1os, como se muestra en el Cuadro 1. Para el ma\u00edz con riego, el coeficiente de variaci\u00f3n promedio es del 8%, mientras que en secano alcanza el 33%.

Las ventajas son claras y las necesidades crecen a\u00f1o a a\u00f1o. Ahora, solo resta que se profundicen medidas que favorezcan la adopci\u00f3n de esta tecnolog\u00eda. Si bien actualmente existen pol\u00edticas p\u00fablicas que promueven la inversi\u00f3n y han contribuido a reducir el costo de instalaci\u00f3n, en 2002 el costo inicial para regar una hect\u00e1rea equival\u00eda a la compra de 1,3 hect\u00e1reas de campo agr\u00edcola, mientras que hoy se ha reducido a un tercio de ese valor. No obstante, es clave impulsar mayores incentivos que aceleren la expansi\u00f3n del riego, considerando el impacto positivo que puede generar en la econom\u00eda nacional. Por ello, es fundamental que el Estado contin\u00faen apoyando esta tecnolog\u00eda, asegurando su acceso a m\u00e1s \u00e1rea y fortaleciendo as\u00ed la competitividad del sector agr\u00edcola.
