This article discusses how new contributions from hydrogeological science in the 20th and 21st centuries have allowed for a better understanding of the processes that affect the maintenance of river flows. Moreover, the way in which this knowledge has been conveyed beyond academia and has been gradually incorporated into public policy for natural resource management is also discussed. This article explains the development of several approaches used to understand the relationships among the management of aquifers, vegetation and river flows, including water balance, aquifer recharge, the piston effect, seasonal effects, and safe and sustainable yields. Additionally, the current challenges regarding the modeling of hydrological processes that integrate groundwater and surface waters are discussed. Examples of studies applied in Brazil that demonstrate these processes and stimulate thought regarding water management strategies are presented. In light of the case studies, it is possible to propose different strategies, each adapted for specific hydrogeological context to maximize aquifer recharge or base flow maintenance. Based on these strategies, the role of infiltration ponds and other artificial recharge techniques is re-evaluated in the context of the mitigation of environmental impacts on the maintenance of river flows. Proposals for the improvement of public policies regarding the payment of related environmental services to stimulate investment in aquifer recharge and the maintenance of base flow, for which the goal is to attain win-win-win situations for the environment, farmers and water users, while preventing land speculation, are discussed. Lastly, a conceptual model for the dissemination of hydrogeological knowledge in public policies is provided, and its challenges and possibilities are discussed.

“…De acordo com Endo (2006), a correlação cronológica entre o Grupo Bambuí e as Formações Vazante, Paranoá e Paracatu ainda não é assunto consensuado na literatura acadêmica. Todavia, as litoestratigrafias completamente distintas, pelas suas litofácies e pela espessura dos sedimentos observados, não deixam de ser critérios para sua separação (Vasconcelos, 2014…”

RESUMOO presente trabalho foi realizado para a região do Araripe, localizada no oeste de Pernambuco. Esta região apresenta importantes modificações em seu ambiente natural, principalmente ocasionadas pela remoção da cobertura vegetal nativa, muitas vezes resultante de desmatamento ilegal para a utilização da lenha como fonte energética nas indústrias gesseiras. Este trabalho buscou separar e quantificar a cobertura vegetal da região estudada a partir do Índice

“…Rapid environmental diagnostics can be an important tool in preliminary surveys for better planning resource allocation for further in-depth diagnostics (Alonso et al, 2011). They are also useful for standardizing field visit procedures for environmental surveillance professionals, which ensures efficiency and equity in impact assessment (Vasconcelos, 2014). Rapid diagnostics have also been used as teaching resources in environmental education, from primary education (Guimarães et al, 2017) to higher education (Callisto et al, 2002).…”

Rapid assessments are useful methods for engaging stakeholders, standardizing monitoring activities and supporting later planning stages. This article proposes to extend rapid assessment methods into ‘rapid environmental planning’ and to use it for the education of planning professionals. For the assessment stage, the pressure–state–response model is used, with a participatory valuation of the ecosystem services through supply and demand profile and future trends. The stage of scenario building includes the XLRM methodology (externalities, actions, metrics and relationships), the trends and evaluation of proposals and uncertainties, as well as the formulation of timelines and narratives. The propositional stage included intervention projects, zoning of land use and occupation guidelines. The methodology was evaluated as a didactic resource for undergraduate teaching in a watershed in São Bernardo do Campo, São Paulo (Brazil). The results indicated a high educational potential for the students as well as the potential effectiveness of this planning method.
