Há mundos sociais que, pelo secretismo das suas práticas, são simultaneamente alvo de grande fascínio e atenção e de grande preconceito e desconhecimento. O "mundo da droga" é um deles. A partir da sua investigação etnográfica, o autor propõe-nos neste livro um percurso pelos territórios psicotrópicos: zonas de periferia urbana onde se vive o quotidiano da venda e do consumo das substâncias psicoativas ilegais. Num estilo mais próximo da narrativa do que do texto académico, somos levados aos lugares onde a experiência comum de cidade se interrompe, dando passo a uma sociabilidade de rua que tem nas drogas o seu elemento central. O livro é, afinal, a proposta de um olhar próximo e interior sobre essa categoria distante dos "mundos marginais", procurando esclarecer os mecanismos que operam na produção das traseiras da cidade e dos seus atores de margem.

This book addresses several issues on water security and governance, helping readers to understand how the desire for water-secure basins can be accomplished through an interplay of water security, water resources management and water policies. The book contains a collection of 12 papers addressing specific as well as interlinked topics within the Special Issue scope. The editors are grateful to all contributors who made the book a reality.

Technology: general issues --- History of engineering & technology --- Environmental science, engineering & technology --- hydroelectric power --- physicochemical parameters --- Iberian Bio-monitoring Working Party index --- riparian forest quality --- riverbank erosion --- restoration --- bank stabilisation --- vegetation revetment --- Bangladesh --- climate resilience --- flood protection --- machine learning --- socio-environmental impacts --- environmental monitoring --- water quality --- surface water --- groundwater --- drinking water --- water quality management --- TMDL --- E. coli --- water reuse --- water availability --- governance --- oasis irrigation district --- stability evaluation --- suitable scale --- irrigation management --- rice --- percolation --- scale effects --- hydrologic cycle --- water security --- precipitation --- drought --- flood --- transport planning --- research gap --- water strategy --- Azraq Basin --- water management --- water governance --- integrated river basin management --- good governance --- flow --- water discharge --- land use --- land change --- SWAT model --- n/a

The immediate goal of this Special Issue was the characterization of land uses and occupations (LULC) in watersheds and the assessment of impacts caused by anthropogenic activities. The goal was immediate because the ultimate purpose was to help bring disturbed watersheds to a better condition or a utopian sustainable status. The steps followed to attain this objective included publishing studies on the understanding of factors and variables that control hydrology and water quality changes in response to human activities. Following this first step, the Special Issue selected work that described adaption measures capable of improving the watershed condition (water availability and quality), namely LULC conversions (e.g., monocultures into agro-forestry systems). Concerning the LULC measures, however, efficacy was questioned unless supported by public programs that force consumers to participate in concomitant costs, because conversions may be viewed as an environmental service.

flood vulnerability --- land use conflicts --- water management --- soil conservation --- spatial multi-criteria analysis --- geographic information system --- water pollution --- riparian forest --- environmental Law --- anthropogenic catchment --- watershed management --- land use policy --- changes in hydrological components --- effects of human activities --- LUCC --- WRUBAP --- Yiluo River --- SWAT --- water balance components --- Land Use and Land Cover changes --- wildfires --- afforestation --- n/a --- riparian buffer width --- landscape composition --- regression model --- interaction term --- Brazilian Forest Code --- farmland abandonment --- LULC changes --- climate change --- runoff/suspended sediment changes --- river morphology dynamics --- Italian Apennines --- water quality --- landscape metrics --- PLS-SEM --- scale --- season --- distance from pollution sources --- script files --- mean diurnal profile --- wavelet coherence --- groundwater recharge --- water resources management --- Conservative Use Potential --- river basin --- water balance --- lakes --- reservoirs --- Nenjiang watershed --- Landsat --- diurnal thermal profile --- urban tributaries --- wavelet --- covariance --- flow --- water discharge ecosystem services --- payments for environmental services --- land use
