“…Brazil is among the biologically richest nations in the world and contains substantial areas for biodiversity conservation (SPAROVEK et al, 2012). The Atlantic Forest occupies an area of 28,586 km 2 in Minas Gerais state, which means 10.3% of the remnants of this land cover in Minas Gerais state (FSOSMA;INPE, 2015).…”

“…Sweeney and Newbold (2014) also emphasized in an analysis of water quality, habitat, and biota protection in small streams that, overall, a forest buffer greater than or equal to 30 m is needed to protect the physical, chemical, and biological integrity of small streams. In Brazil, Permanent Preservation Areas (PPAs) or riparian buffer areas are used to protect water resources, soil and biodiversity and serve as green corridors in the landscape (SPAROVEK et al, 2012). Thus, a detailed overview of PPA widths, established for the purpose of environmental conservation, can be found in the Brazilian Forest Act 12651/2012 (BRASIL, 2012).…”

ABSTRACT:In recent years, concerns regarding the impacts of deforestation of riparian vegetation on water resources have created social and political tensions in Brazil. This research analyzed simulated hydrologic components of a 6.76 km 2 headwater watershed with different widths of riparian vegetation. Lavrinha Watershed (LW) hydrological responses were simulated using the Distributed Hydrology Soil Vegetation Model (DHSVM), which was forced using meteorological data from one station (2005)(2006)(2007)(2008)(2009)(2010). Land cover scenarios where the percent land cover of Atlantic Forest was increased from the control resulted in changes in hydrologic components in the watershed due to increased evapotranspiration and rainfall interception and reduced runoff and overland flow. The base flow/runoff relationship has increased, suggesting that riparian vegetation plays an important role in groundwater recharge. Modeling of hydrologic components linked to riparian buffer scenarios, such as the process used in this study, can be a useful tool for decision-making strategies regarding watershed management. IMPACTOS HIDROLÓGICOS DEVIDO ÀS ALTERAÇÕES NA LARGURARIPÁRIA EM UMA BACIA HIDROGRÁFICA DE CABECEIRA RESUMO: Nos últimos anos, as preocupações quanto aos impactos do desmatamento da vegetação ripária nos recursos hídricos criaram tensões sociais e políticas no Brasil. Esta pesquisa analisou os componentes hidrológicos simulados de uma bacia hidrográfica de cabeceira de 6,76 km 2 com diferentes larguras de vegetação ripária. As respostas hidrológicas da Bacia Hidrográfica Lavrinha (BHL) foram simuladas utilizando o Distributed Hydrology Soil Vegetation Model (DHSVM) que foi forçado usando dados meteorológicos de uma estação (2005)(2006)(2007)(2008)(2009)(2010). Os cenários de cobertura do solo em que o percentual da Mata Atlântica foi aumentado do controle resultaram em mudanças nas componentes hidrológicas na bacia hidrográfica devido ao incremento da evapotranspiração e intercepção da precipitação e redução do escoamento total e escoamento superficial. A relação escoamento base/escoamento total aumentou, sugerindo que a vegetação ripária desempenha um papel importante na recarga de água subterrânea. A modelagem dos componentes hidrológicos, associada aos cenários de larguras ripárias, como o processo utilizado para este estudo, pode ser uma ferramenta útil para as estratégias de tomada de decisão referente à gestão de bacias hidrográficas.

“…The demand also decreased because of the pardon of the deficit of the LR granted to small properties (moved from the category of debtors to creditors). The imbalance between supply and demand for the CRA represented the largest obstacle to the consolidation of this market (SPAROVEK et al, 2012;MAY et al, 2016). The absence of a CRA market and of other measures capable of promoting payment for environmental services may lead to the illegal deforestation of the remaining areas, for which conservation incentives may not be available.…”
