abstract = "Increasing demand for water is one of the most challenging
problems that human societies face today and has encouraged new
studies to examine water security and water management. Seeking to
discuss this important issue in the Brazilian context, we analyzed
the impacts of urban expansion on water security in a basin
located in the most populated region of Brazil. To quantify
increased water demand, we combined urban sprawl and regional
population increase projections. In this context, our study
contributes to discussions on water security by addressing the
importance of integration between water and urban planning.
Simulations indicate good performance in reproducing actual water
system conditions. The finding demonstrates that urban expansion
in the region is mainly driven by road proximity. Urban occupation
is projected to increase in 170% by 2050, increasing water demands
for domestic use in 38%. Results indicate the feasibility of
including landscape and socioeconomic constrains in order to
obtain potential domestic water demand scenarios by using land use
and land cover change modelling to assess urban expansion and
population growth. For the study region, our findings suggest that
although urban sprawl increases water demand, urban supply will
not be compromised given the large volume of available water in
the basin. However, the indirect consequences of urban sprawl,
such as industrialization and agricultural intensification, may
compromise the quality of this resource and require better water
use management in the region.",
