Resumen:
The accelerated growth of cities associated with the absence of urban planning
sensitive to water resources can lead to numerous impacts on infrastructure services,
especially in water supply systems. Therefore, the generation of future scenarios to
obtain an estimate of the increase of water demand over the years is essential for an
efficient urban planning, and can help in the development of plans that make it possible
to indicate guidelines that are more appropriate to the environment urban. Thereby,
the objective of this work was to estimate the future water demand of the Itararé district,
located in the city of Campina Grande, using current land use and occupation data,
and four future scenarios produced through water consumption estimated for the
population projection of the neighborhood in the short term, t = 5 years; and Medium
term, t = 10 years. For this purpose, geotechnologies, such as QGIS software, were
used to generate the current spatial consumption of water in the neighborhood and the
Google Earth Pro visualization platform that assisted in the study of the evolution of
the built area. The temporal analysis of the occupation of the study area showed a
great rise of the built area in the period from 2005 to 2018 and the estimation of water
demand for the future scenarios presented an 11% increase in water consumption
between the short, and medium term. In comparison to current water demand, the
future scenarios predicted through the population projection of the neighborhood by
the AiBi method indicated that the Itararé neighborhood already has a demand for
water higher than that projected for 5 years, evidencing the change in the growth
dynamics of the neighborhood over the years.
