             abstract = "Public policies affecting land use/land cover also have an impact 
                         on water resource availability, and hilltop protected areas are a 
                         relevant factor in ensuring continued availability of water 
                         resources. The legislation ruling the delimitation of protected 
                         areas on hilltops has changed at the Brazilian national level in 
                         2012 and in Rio de Janeiro state in 2014. However, these 
                         environmental legislation changes did not take into account the 
                         feedback effects of restricting protected areas to hilltops on the 
                         regularity of hydrological responses in watersheds. As such, this 
                         manuscript sought to analyze the contribution of hilltop-only 
                         protected areas to continued water availability. We analyzed 
                         hydrological responses in the Sao Joao river watershed, which 
                         provides water for domestic, industrial, and agricultural uses in 
                         the Regiao dos Lagos municipalities of Rio de Janeiro state. Our 
                         results show that designating only hilltops as protected areas, as 
                         prescribed under the new pieces of legislation, does not prevent 
                         abrupt changes in hydrological responses that can lead to changes 
                         in streamflow volume and regularity as well as increases in 
                         sediment flows, which may compromise drainage systems and 
                         continued water supply due to reservoir silting. Therefore, we 
                         conclude that protecting hilltops only, as established under 
                         current Brazilian legislation, is not sufficient to safeguard the 
                         environmental function of maintaining water resource 
                         availability.",
