Title A name given to the resource Pastura natural de salto (Uruguay): relación con la variabilidad climática y análisis de contextos futuros de cambio climático Natural pasture in salto (Uruguay): relationship with climate variability and analysis in the context of future climate change Creator An entity primarily responsible for making the resource María Laura Bettolli, Miguel Ángel Altamirano Del Carmen, Gabriela Cruz Brasesco, Frederico Rudorff, Arlen Martínez Ortiz, Jacinto Arroyo, Jorge Armoa Description An account of the resource En este trabajo se evaluó objetivamente la relación entre la variabilidad del rendimiento de la pastura en el departamento de Salto (Uruguay) y la variabilidad climática. Se analizaron también las posibles implicancias del cambio climático futuro. Se utilizaron datos diarios y mensuales de la estación meteorológica Salto en el período 1961-1990 y un registro de datos experimentales de crecimiento de pastura en el período 1980-1994. Adicionalmente, se emplearon salidas diarias de reanálisis del NCEP y de los Modelos de Circulación General HadCM3 y CSIRO-Mk2 para los escenarios A2 y B2. Las correlaciones simples entre las variables climáticas y la pastura confirmaron en términos cuantitativos la sensibilidad de la pastura a la variabilidad climática, explicando entre el 20% y 58% de la varianza en los rendimientos. Las mayores asociaciones se encontraron en otoño (principalmente con las variables relacionadas con la precipitación) y verano. En invierno no se observaron asociaciones significativas. El efecto conjunto de las variables climáticas explicó entre el 36% y 86% de la variabilidad en el crecimiento de la pastura. Para los escenarios estudiados, los incrementos proyectados en las temperaturas mínima y máxima permitirían reducir las probabilidades de ocurrencia de temperaturas por debajo del umbral mínimo considerado para la pastura (10ºC) y aumentar las probabilidades de estrés térmico durante el verano. La precipitación presentaría incrementos que podrían aumentar la incidencia de excedentes hídricos en invierno. Los incrementos proyectados para el verano no compensarían los aumentos de la demanda hídrica atmosférica por mayores temperaturas.This work aimed to evaluate the relationship between natural pasture yield and climate variability in the district of Salto (Uruguay), and to analyze the possible implications of future climate change. Daily and monthly data from Salto meteorological station for the period 1961-1990 were used together with experimental data of pasture yield for the period 1980-1994. Moreover, NCEP reanalyses of daily data as well as daily outputs from General Circulation Models HadCM3 and CSIRO-Mk2 were analyzed. The simple correlations between the climatic variables and the pasture yield confirm in quantitative terms the sensitivity of pasture yield to climate variability, accounting for 20% up to 58% of the variance. The highest associations were found in fall (mainly with precipitation variables), followed by summer. No significant associations were found in winter. The joint effect of the climatic variables on yield could explain between 36% and 86% of the pasture variability. The increments projected for the minimum and maximum temperatures may, respectivaly, reduce the probabilities of occurrences of temperatures below the minimum threshold considered for pasture (10ºC) and increase the probabilities of thermal stress, mainly in summer, respectively. Modeled increments in precipitation may raise the occurrences of precipitation excess during winter. On the other hand, the modeled precipitation increments during summer would not be enough to compensate the high water demand caused by the greater temperatures.
