TITLE:

ANALYSIS OF WATER VULNERABILITY IN THE SOUTHWEST REGION OF BAHIA

KEY WORDS:

Water resources, anthropic actions, land use, climate change, watershed

BIG AREA: Outra
AREA: Multidisciplinar
SUMMARY:

The reality concerning water resources has instigated the whole world to develop governmental and social measures that aim to develop preservation and care practices with water. Even though water is extremely important for the maintenance of human life, it has suffered environmental impacts over time due to human actions. The impacts resulting from anthropic actions and the inadequate use of the soil cause serious environmental problems, leading to sedimentation and silting up of the springs, causing a reduction in the availability and quality of the water. Water resource monitoring and management practices are needed regarding the use and land use of river and watershed boundaries, especially in the context of climate change. The present research aims to understand the context of water vulnerability of the southwestern territory of Bahia, and for this it will be necessary: (i) Map the water balance of the municipalities of the identity territory (ii) Identify the changes in precipitation volumes over the years and verify the trend of future change in precipitation volumes (iii) Describe the climate variability of the semi-arid region of Bahia (iv) Verify the impact of climate change on water resources in southwestern Bahia (v) To map the patterns of land use and occupation in the watershed of the southwestern territory of Bahia (vi) To analyze the potential impacts of climate change on the water resources of southwestern Bahia (vii) To disseminate better management techniques for agricultural irrigation. To delimit the watershed areas that will be studied, images from the Shuttle Radar Topography Mission database of the Brazilian Geomorphometric Database (INPE, 2020), with a spatial resolution of 30 meters, will be used. The hydrological analysis will use information from historical series of the river gauge stations that are within the basins and that have current data series. In order to determine whether or not there is a direct relationship
between hydrological variables and land use and land cover classes, Pearson correlation coefficients will be calculated. It is expected to propose and disseminate better agricultural management techniques, especially in irrigation management, because it will have the estimate of monthly precipitation volumes, as well as estimates of evapotranspirometric volumes, making a water balance, being able to propose the necessary volumes of water supplemented by irrigation. It is hoped that this will alleviate the problem of water scarcity in a sustainable way, besides contributing to the generation of income and to the social development of the local community, allowing the semi-arid region to establish itself as a center for agriculture.
