abstract = "Population growth and the expansion of human activities are
expected to increase by 55% the demand for water resources in the
next 35 years. This demand expansion, associated to expected
changes in climatic events, highlights the need to better monitor
and manage water resources to ensure its long-term provision. We
investigated the effects of land cover and precipitation on the
quantity and quality (turbidity and dissolved soil) of water
delivered to rivers in S{\~a}o Paulo state, Brazil. We analyzed
water quality and quantity data from 2000 to 2015 and modelled
these variables as a function of the following covariates:
percentage of different land cover types (forest, silviculture,
sugarcane, pasture and urban), accumulated precipitation before
sample collection, MODIS-Enhanced Vegetation Index (EVI), dominant
soil class and watershed area. In all our models, EVI was an
important predictor of water quality and quantity. Although we
detected a negative effect of forest cover on turbidity, there is
a positive and stronger effect of agricultural EVI, relative to
forest cover, increasing turbidity. These results suggest that
reducing sediment inputs into rivers will require both forest
conservation and soil protection in agricultural lands. The extent
of forest cover and forest EVI were negatively associated with
variation in river levels, suggesting that high vegetation
structure/biomass stabilizes water flow in these rivers. We
conclude that high temporal resolution EVI can help understand the
effect of land cover on water provision. Finally, it is essential
to protect and increase forest cover to ensure the stability of
water provision.",
