             abstract = "The Nilo Coelho irrigation scheme, located in the semi-arid region 
                         of Brazil, is highlighted as an important agricultural irrigated 
                         perimeter. To analyze the land use change effects inside this 
                         perimeter, the large scale values of biomass production (BIO) and 
                         actual evapotranspiration (ET) were quantified from 1992 to 2011, 
                         under the naturally driest conditions along the year. Monteith´s 
                         radiation model was applied for estimating the absorbed 
                         photosynthetically active radiation (APAR), while the SAFER 
                         (Simple Algorithm For Evapotranspiration Retrieving) algorithm was 
                         used to retrieve ET. The highest incremental values of BIO as a 
                         consequence of the land use change happened in 1999 and 2005 when 
                         the average differences between irrigated crops and natural 
                         vegetation were more than 70 kg ha-1 d-1. Comparing the ET rates 
                         of 1992 (1,6 mm d-1) with those for 2011 (3,1 mm d-1), it was 
                         verified that the extra water consumption was doubled as a result 
                         of the increasing in irrigated areas. More uniformity along the 
                         years on both water productivity parameters occurred in natural 
                         vegetation, evidenced by the lower values of standard deviation 
                         when comparing to irrigated crops. The heterogeneity in ET values 
                         under irrigation conditions are due to the different crop stages, 
                         cultural and water managements. The models applied at the 
                         irrigation perimeter level are considered to be suitable for 
                         quantifying the land use change effects on regional biomass 
                         production and water consumption in the Brazilian semiarid region, 
                         however, to transfer them to other agro-ecosystems, probably, the 
                         regression coefficients of the equations should be calibrated.",
