The anthropogenic derivations materialize in the geographic space several contradictions, these being fomented by the economic, political, social and cultural interventions of the human relations with the nature, coming from the accelerated increase of the consumption, the lack of planning and socioenvironmental management that respects the fragilities of the environment. Understanding this reality, the dissertation was built with the perspective of performing integrated landscape analysis, considering the inheritance of biophysical processes, articulating positive and / or negative interventions. In this dimension, the central objective is to evaluate water potential, along with anthropogenic processes, from the socio-environmental perspective, in the upper reaches of the Subaé River, in Feira de Santana-BA. In order to reach such a north, the research was guided by the theoretical-conceptual knowledge of discussions about Hydrographic Basins (spatial management unit), Landscape (integrated category of geographic science) and socio-environmental approach in the context of conflicts between society and nature, a practical effort carried out through the field activities, where the empirical data collected was verified and updated, and at the same time a space for identifying the nuances of the historical relations developed in this environment, as well as the support of institutions that foster research in the State and in the country, such as UEFS, CONDER and INMET, which provided essential secondary data for the understanding of temporal analysis. In this way, the combination of such information contemplates the understanding of the scenarios of the study area. It should be noted that the high course of the Subaé River presents an important landscape potential that has been shaped throughout geological time, and that, in a certain way, favors the maintenance of current biophysical characteristics and dynamics. This adaptive capacity guarantees the maintenance of the drainage network, in view of the climatic, biological and structural diversity it presents. Understanding this dynamic, it is concluded that: through the encouragement of the Union, the Subaé river and consequently the springs will have great difficulty to remain present in the landscape in the sector located in the city of Feira de Santana. The negative anthropogenic derivations identified promote an optimistic scenario of preservation or recovery of these areas. The advance through the invasion of real estate speculation, the attraction of new industries or expansion of those that already exist reinforce the existing logic of environmental degradation, since the neglect with environmental conditions has been presenting intense discomforts in urban and rural environments, such as floods, (erosion) and vegetation cover, reduction or lack of water, besides the difficulty of the performance of agricultural and industrial activities. This sectorization of high-level drainage will involve the reorganization of water dynamics, alteration of water flow and the interrelation with other environmental constraints, mainly anthropic.
