The present work had as general objective the potential and emergent environmental fragility of the Japaratuba River Basin (BHRJ) in the state of Sergipe, aiming at the definition of standards of the tests. The tests were basically the Hierarchical Process - AHP and algebra of maps. The AHP method was used in order to allow the weighting and hierarchy according to the order of the variables used for an analysis of the potential environmental fragility of the BHRJ and the map algebra was used to perform the integration of the variables generating as products maps of potential and emerging environmental fragility. The results obtained are three classes of ecodynamic units, one saber: stable (13.44%), intergrades (71.45%) and unstable (15.11%), based on the analysis of the environmental fragility of the area of study. It concluded that anthropogenic intervention influenced the environmental fragility of the BHRJ, presenting an urgency of alternatives for the restoration of exogenous geodynamic balance, from the adoption of conservationist practices. The use of the AHP technique is a map algebra for the mapping of the environmental fragility, since AHP minimizes the occurrence of errors in determining the weights for the necessary variables and the map algebra performs the integration process , which facilitated the elaboration of the mapping. The adopted systematics generated a technical document of subsidy of management of the use and the occupation of the soil and of the superficial water resources for a study area.
