It is therefore important that objective assessments of the current use of water are undertaken on a routine basis. New remote sensing technologies now provide an opportunity to assess and monitor water use at farm and catchment scales. This study demonstrates the use of satellite-based estimates of evapotranspiration (ET) and NDVI (Normalised Difference Vegetation Index) in irrigation performance indicators that relate crop water use to crop water requirement (CWR) in the Goulburn-Murray Irrigation Region of South-Eastern Australia. The METRIC energy balance algorithm (Allen et al 2007) was used to derive ET estimates from Landsat satellite data. 1. INTRODUCTION Irrigation dominates agriculture in the Goulburn-Murray Irrigation Region of south-eastern Australia. The Catchment, located in Victoria, Australia, between 35° 06' and 36° 42" S latitudes, and 143° 18' and 146° 01' E longitudes accounts for an area of about 68,000 sq km, and includes the key irrigation areas of Central Goulburn, Shepparton, Rochester-Campaspe, Pyramid-Boort, Murray Valley and Torrumbarry. It is one of the most important agricultural regions in Australia with major irrigation-based industries that include dairy, horticulture and viticulture enterprises. Irrigated agriculture consequently has a major impact on available water resources in the region, and the sustainable management of the increasingly limited water resource requires repeated objective assessments of irrigation water use (supply) in relation to the demand for water, set by crop type, crop water requirement (CWR), crop area and seasonal weather conditions (evaporative demand + rainfall). This study demonstrates the use of Satellite Remote Sensing to support comprehensive, affordable irrigation water use assessments, and improved irrigation management in the Catchment. The study focused on a fundamental indicator of irrigation performance, namely the relationship between farm total crop water use (‘water supply’, TWS) and crop water ‘demand’, measured as CWR. Comparisons of TWS in relation to CWR rapidly identify issues of under- and over-supply of irrigation water on farms. 2. METHODS The study compared measures of TWS and CWR in the irrigation season 2008-09. Landsat satellite images for 2008-09 were used to identify areas of active irrigation, and to derive estimates of CWR. Pixel-scale estimates of CWR were derived from the standard equation: * : . > oii Corresponding and presenting author: mohammad.abuzar@dpi.vic.gov.au CWRp = 2. (Kc ETr-R) (1) where Kc was the crop- and field-specific ‘crop coefficient” appropriate to the irrigated field, ETr was ‘alfalfa’ ‘tall-crop’ reference crop evapotranspiration (Allen et al 2006), and R was ‘effective’ rainfall (McAllister et al 2009). The summation in Equation 1 depended on crop, and was extended over the seasonal duration of active irrigation of a crop. Field-scale and farm-scale estimates of CWR were derived by integrating values of CWR, over pixels-within-fields and fields-within-farms, respectively. Meteorological data appropriate to the calculation of ETr and R were sourced from SILO website (http://www .longpaddock.qld.gov.au/silo/) for two locations (Shepparton and Swan Hill). ^ NDVI-dependent crop- and region-specific estimates of Kc (Whitfield et al 2011) were used to make pixel-specific estimates of Kc for use in Equation 1. Crop- and region-specific estimates of Kc made according to Whitfield et al (2011) were based on relationships that described the dependence of satellite-derived rates of ET on associated measures of NDVI. Satellite measures of ET and NDVI were made using a variant of the METRIC method (Allen et al 2007) that used the empirical relationship of Teixeira et al (2009) to describe surface roughness as a function of NDVI and surface albedo. Horticulture in the Goulburn-Murray Irrigation Region is dominated by long-lived perennial plantings. Land use and crop types on horticultural fields are therefore relatively stable over time. The areal extent of fields within horticultural farms and associated crop type were sourced from land use maps provided by Shepparton Preserving Co. (SPC). By contrast, both annual and perennial pastures are important on irrigated dairy farms. Seasonal variations in satellite-derived representations of the VIT space, which describes land surface temperature as a function of NDVI (Abuzar et al 2008), were used to categorise irrigated dairy fields into annual and perennial classes.
