             abstract = "The Enviromental Protection Area (EPA) of Banhado Grande is an 
                         important wetland area in Rio Grande do Sul, which is 
                         significantly altered. Since the 40s, the basin has been heavily 
                         occupied by agricultural area for rice cultivation, draining their 
                         flooded areas, turning waterways into a grid of irrigation canals. 
                         Some of the problems associated with rice irrigation also refers 
                         to the lack of control over the use of river water for this 
                         purpose. With the objective of quantify and identify the areas 
                         occupied by rice cultivation along a temporal serie of images on 
                         the EPA of Banhado Grande, aiming to evaluate the possible impacts 
                         on the wetland areas, through remote sensing techniques was 
                         conducted the mapping of rice cultivation areas. Also was defined 
                         the Banhado Grande system as the area bounded by altimetric 
                         elevation of 20 meters. The mapping was developed by visual 
                         interpretation of the images, besides analyzing the spectral 
                         behavior patterns as shape and texture. Were created relationships 
                         between the land use and occupation and the rice cultivation in 
                         this area of environmental conservation, where there is change in 
                         the size of the original wetlands, caused by the implementation of 
                         irrigation canals for rice cultivation,by the land use management 
                         through crop rotation, by intensifying production in areas with 
                         higher water availability and improper cultivation of rice in 
                         areas of wetlands, impacting the flora and fauna, and its 
                         regulatory capacity in the Gravata{\'{\i}} river flow.",
