The Cerrado savanna of Brazil is considered the most biodiverse savanna in the world and its vegetation acts as an interface between rainfall and recharge processes for the largest aquifer system (Guarani) in South America. Understanding how major Cerrado tree species affect the amount and patterns of rainfall at the surface, therefore merits scientific attention. Some rainfall that contacts the Cerrado canopy will be drained to a concentrated area around the stem base as ‘stemflow.’ Hypothetically, this spatially concentrated hydrologic flux may contribute nontrivially to recharge. Here, we examine stemflow variability over 13 months for 151 trees, representing 36 species common to the region, with a large range in stem and canopy structures. Bark texture, stem diameter at breast height (D) and the canopy height-to-width ratio (H:W) were measured for all trees, then individuals were sorted into three classes: smooth, scaled and furrowed bark texture; < 10, 10–20 and > 20 cm D; and < 1, 1,2 and > 2 canopy H:W. These data were used to investigate how tree morphological traits influence stemflow in the Cerrado. Stemflow over the study period represented 2.5% of rainfall, and the contribution of each morphological class to the region's scaled total stemflow yield was calculated. Although median stemflow volumes per storm were significantly different between bark textures (smooth > scaled > furrowed); the interrelated effects of canopy structure (H:W) and tree size (DBH) resulted in a relatively well-balanced representation of all bark classes to the Cerrado's total stemflow yield (41% from smooth-barked trees, 30% scaled-bark trees, and 29% furrowed-bark trees), regardless of the density of individuals belonging to each class analyzed. Large trees (D>20) with low canopy H:W<1 and scaled bark produced the lowest median stemflow fractions. The highest contribution to stand-scale stemflow yield in this Cerrado study was linked to the combination of stem and canopy traits in three ways: (1) trees with smooth bark dominated by D<10 and H:W1-2; (2) trees with D10–20 dominated by smooth bark and H:W1-2 ratio, and (3) trees with H:W1-2, dominated by smooth/furrowed bark trees and D<10. These findings highlight the importance of trait-based approaches in studying how tree stem (bark), size (DBH), and canopy (H:W) structural traits interact to affect stemflow generation, while filling a knowledge gap regarding the ecohydrology of the Brazilian Cerrado.

Just to the south of the Amazon, there is a vast and biodiverse savanna that scientists believe is under even greater threat, called the Cerrado. Scientists want to understand how the plants that live in the Cerrado affect the rainfall that enters the ground to recharge the aquifer. Many of these plants are trees that capture rainwater and drain it down their bark-covered branches and trunks. This water, called stemflow, may be one way to recharge the aquifer, if the branches and bark of the trees are the right size and shape. This article will introduce the common plant species of the Cerrado, describe how they affect the way rainfall enters the ground, and discuss how bark and branches may help conserve water.

Few investigations have examined the structural controls of bark on its water storage and influence on stemflow, despite the bark being considered a critical component that determines the time and magnitude of this process. This study seeks to answer the question: Do bark water absorbability and wettability estimates correlate with stemflow yield? We hypothesized that (1) the absorbability and wettability are correlated, that is, greater water absorbability implies greater wettability, and (2) high rates of bark water absorbability and wettability has a strong and negative correlation with stemflow generation. Stemflow yield (Sy) was monitored over 12 months for 31 trees, representing 9 species common to the Brazilian savanna ecosystem known as Cerrado. Bark absorbability, per unit dry weight, changes over time of the water absorbability (BWA - by submersion methodology), bark drying (BWD), bark absorbability rate (BWArate), bark drying rate (BWDrate), and wettability (initial contact angle – CAin and CA rate - CArate) were determined under laboratory conditions. As insoluble lignin may also act to alter bark water storage dynamics, for each species, the bark insoluble lignin content was characterized. Stemflow variability was significant across the study species. Funneling ratios (FR) indicates that all species’ canopies diverted enough rainfall as stemflow to concentrate rainwaters at the surface around their stem bases (FR > 1). Differences in bark water absorbability were notable some of tree species. A decrease in the CA value as a function of time was not observed for all barks, which in association with stemflow yields, allowed a novel classification method of wettability, based on CAin and it’s rate of change: highly wettable (CAin ≤ 75.3° and CArate ≥ 0.26°h–1) and non-wettable (CAin ≥ 93.5° and CArate ≤ 0.13°h–1). So, only from the wettability classification could be observed that the non-wettable bark species presented higher Sy, FR, BWA, and BWArate than highly wettable bark species. The stemflow from species with highly wettable bark had a strong and positive correlation with BWA. On the other hand, non-wettable bark stemflow yield has a strongly and negative correlation with FR, CAin, and BWArate. Thus, bark wettability properties showed to deserves special attention. This novel classification of bark wettability had a substantial effect on stemflow yield comprehension and proved to be an important variable to link laboratory and field investigation for understanding the stemflow yield. These findings will improve our understanding of the stemflow dynamics, water balance and the ecohydrology processes of forest ecosystems.

After several landscape transformations caused by human activities, finding a suitable environment becomes increasingly challenging in urbanized regions. The predominance of non-permeable areas results in a low level of water infiltration. Notwithstanding, even green areas can have high runoff rates, since soil compaction has a decisive influence on the water movement. In places that have a natural predisposition to overflow, these problems are more significant. This study aimed to investigate causes of flooding, highlight the benefits of urban gardening and to propose urban gardening as an alternative to soil improvement in the Corujas Watershed, São Paulo, Brazil. The evaluation was based on: (a) the physical characteristics of the watershed, provided by morphometric analysis and land-use analysis; and (b) the soil compaction rates of an urban garden compared to a riparian forest and a grass area. The morphometric results indicated that the watershed has a significant flood tendency, and the land use map demonstrated that 29.55 % of the soil has some permeability. Nevertheless, this permeability currently varies according to soil management and cover. The grass area presented the highest compaction rates, the riparian forest a medium rate, and Corujas Garden the lowest rate. The garden also has green infrastructures and good management practices, which have led to the appearance and perpetuation of diffuse springs. These results showed that the urban garden activities could improve the physical characteristics of the soil and optimize water infiltration. Subsequent studies will investigate whether this characteristic also applies to other gardens located in different urban watersheds.

Quantitative studies on the water and nutrient enrichment of throughfall and stemflow in the Cerrado are lacking, especially among tree species. This work tested the hypothesis that the chemistry of rainfall fractions is altered after passing through the canopy and that the chemistry of stemflow can substantially change among tree species. We compared the nutrient concentrations in rainfall, throughfall and stemflow, dry deposition and canopy exchange among eight Cerrado species in Brazil. Rainfall, throughfall and stemflow were monitored from April 2018 to March 2019. The following chemical factors were determined using a Metrohm liquid chromatograph ECO IC: Na2+, K+, Ca2+, Mg2+, Br−, Cl−, NO3−,SO42−and PO43−. The enrichment ratio, depositions of rainfall, throughfall and stemflow and canopy budget of different nutrients were calculated for the stand and species. A comparison between the mean concentrations showed that most of the elements and compounds were relatively more concentrated in the throughfall and stemflow, except for Na2+and Ca2+, which were more concentrated in the rainfall (p<0.05). We noted that each species had a specific contribution to the stemflow nutrients. The different components and canopy geometry, as well as the bark morphology of the studied species, contributed varying proportions to the nutrient fluxes. The stemflow deposition of most nutrients was significantly higher in Xylopia aromatica. The highest nutrient input by stemflow was observed for K+, which ranged from 2.13 (A. peregrina) to 77.36 (X. aromatica) kg ha−1 y − 1. A canopy budget model indicated that canopy exchange was often more dominant than dry deposition. Unlike the other nutrients, Cl− and PO43− were taken up by the canopy. Given the variation in the nutrient input, these results highlight the importance of investigating the individual contribution of the stemflow of each species in the Cerrado forest and provide a potential strategy for adapting the species to soil recovery.

Although the scientific knowledge about some associations between physical parameters of the soil is consolidated, studies focused on investigating the dynamics of forest restoration processes and the structure of soils remain incipient. The study area is located in Cerrado and is called as Private Natural Heritage Reserve (RPPN) Águas Perenes Forest (perennial water forest) and was selected as a “High Conservation Value Forest”, provides scope to investigate the soil physical properties recovery on passive restoration sites, with different ages but with the same land use history. So, the aim was to investigate the soil density, moisture, penetration resistance and infiltration rate with long-term from old (FA, 46 year-old), medium (FB, 11 year-old) and young (FC, 8 year-old) passive restoration sites. It was observed differences in soil density, as well as in soil moisture, resistance to penetration and infiltration rate. Mean densities recorded for FA, FB and FC were 1.38, 1.48 and 1.53 g cm−3, respectively. FA recorded higher mean soil moisture (14.9%) than FB (11.5%) and FC (10.0%), whereas mean soil resistance to penetration was increased from FA (0.87 MPa) to FB (0.91 MPa) and FC (1.10 MPa). The average infiltration rate was almost similar in FA and FB (FA = 76.43 mm h−1; FB = 77.48 mm h−1) and approximately 39% higher than FC (55.79 mm h−1). Thus, although soil density and moisture were different in each passive restoration site, 11 year-old passive restoration site showed similar resistance to penetration and infiltration rate to the old (46 years) passive restoration site. These features allowed seeing improvements in hydrological maintenance in the soil and revealed that passive restoration in Cerrado is able to improve the physical features on a soil presenting similar texture, climate and management history.

A Amazônia é reconhecida como a maior floresta tropical do mundo, onde a floresta interage fortemente com a atmosfera, rios e lagos, exercendo significativa influência no clima local e global. Quantificar a influência da floresta sobre os processos hidrológicos que direta ou indiretamente influenciam o clima é de fundamental importância para os esforços de conservação. No sentido de identificar o perfil da produção científica relacionada à hidrologia florestal na Amazônia, foi realizada uma análise dos artigos publicados em periódicos científicos nos últimos 20 anos, em termos quantitativos, qualitativos e de origem da autoria, de forma a contribuir para o aprimoramento e a promoção de pesquisas futuras relacionados ao bioma. A base de dados utilizada para a realização das buscas foi o “Periódicos Capes”, e os termos de busca foram: Stemflow, Throughfall, Runoff, Interception, Water Balance, Hydrology. Foram selecionados apenas os trabalhos desenvolvidos no bioma amazônico. As buscas retornaram um total de 46 artigos, com média anual de 2,3 artigos publicados. Os artigos foram publicados em 28 periódicos distintos, sendo 25 internacionais e somente 3 nacionais. Para os periódicos internacionais, os fatores de impacto foram, em todos os casos, bastante expressivos. Constatou-se que 70% dos trabalhos são resultado de cooperações entre institutos de pesquisa/ensino nacionais e internacionais, bem como entre pesquisadores. Foi possível concluir que a produção bibliográfica na área de hidrologia florestal na Amazônia ainda é incipiente. Porém, os poucos artigos foram publicados, majoritariamente, em periódicos de alto impacto, evidenciando a relevância do tema para a comunidade científica internacional.

The importance of stemflow to hydrology and biogeochemistry in forest ecosystems is highlighted by the growing interest of the scientific community since the 1970s. This paper summarizes the main contributions of stemflow (SF) studies from recent years through a systematic review of the literature, including 375 scientific articles published between 2006 and 2019. Shrub SF has shown superior efficiency (11.1%) compared to tree species (3.6%). Branches, bark texture and composition, branch and leaf saturation capacity, and wind intensity were identified as factors that significantly influence SF. However, despite the increasing number of publications on the subject, most of them focus on semi-arid regions of Asia, particularly of China, and temperate regions. Thus, there is still a lack of knowledge about the role of the different species in the biogeochemical cycle concerning the SF in tropical and semi-equatorial regions.

Although recognized as a hotspot, being one of the most diverse biomes in Brazil and responsible for recharging the main aquifers in South America, the Cerrado has been suffering from intense deforestation. Since rainfall, after reaching the forest canopy, has its physicochemical features altered by the metabolites leaching from the leaves tissues, branches, and stem, this study was developed in order to obtain information about the hydrological processes in the biome and the potential of nutrient input by their forest species. There is a lack of studies as proposed in natural environments such as Cerrado. Based on this, we have evaluated the relative importance of stemflow and throughfall solute concentrations to the soil surface in a Cerrado forest in Brazil and also the potential of stemflow by 8 Cerrado species to soil nutrient input. The following chemical aspects from rainfall, throughfall and stemflow were determined: Na2+, K+, hardness (Ca2+ and Mg2+), Cl-, , PO3- and on a liquid chromatograph Metrohm ECO IC during august to december 2018. The comparison between mean concentration, showed that most of the elements and compounds were more concentrated in throughfall and stemflow, except for Na2+ and Ca2+, which were more concentrated in rainfall (p <0.05). While the amount of stemflow channeled to the tree trunks comprised approximately 4% of rainfall, some nutrients in stemflow were enriched up to 10-fold in comparison to throughfall and rainfall. When we have discriminated the solute concentration by stemflow between 8 forest species from Cerrado, we have noted that each species has a specific contribution to the stemflow nutrient and for most of the species, the ion concentrations in the stemflow water is higher than those found in the rainfall and throughfall. Xylopia aromatica has shown the major difference between the solute concentrations when compared within other species. The total input of nutrients fluxes, as the amount of rainfall loading had been ranked as follows: K+ > Ca2+ > Mg2+ > NO3 > > > Cl- > Br-. The highest nutrient input by stemflow was for K+, which ranged from 7.91 (H. ochraceus) to 114.08 (X. aromatica) kg ha-1.These results highlight the importance of investigating the individual contribution of each species in the stemflow in Cerrado forest, suggesting a variety in nutrient input through the biogeochemical cycle and could be a strategy to accommodate the species for soil recovering. The knowledge of the biogeochemical dynamic helps to understand the processes that are responsible for the sustainability of forest ecosystems and the forest ecosystem plays an important role in water balance, not only in terms of water quantity (volume) but also in the distribution of the chemical elements.

RESUMO A presente pesquisa teve como objetivo avaliar a dinâmica da recuperação ambiental de pilhas de estéril de mineração de calcário por meio da análise da composição e estrutura fitossociológica da regeneração natural. O estudo foi conduzido em um empreendimento minerário localizado em Salto de Pirapora (SP), Brasil, com pilhas de estéril abandonadas desde 1994 e 2013, e um fragmento florestal nativo, totalizando três tratamentos. Em cada área, foram alocadas 12 parcelas de 10 × 10 m, onde todos os indivíduos arbustivo-arbóreos com altura acima de 1,30 m foram amostrados, identificados e avaliados quanto à composição e à estrutura fitossociológica. Foi constatada a ocorrência da regeneração natural nas pilhas de estéril com o aumento de indivíduos e espécies ao longo do tempo. Os resultados indicam que a vegetação presente nessas pilhas está em transição de floresta pioneira para um estágio sucessional mais avançado. Contudo, a Leucaena leucocephala estabeleceu-se mais expressivamente que as demais, inibindo o desenvolvimento de outras espécies. Por fim, sugerem-se ações de manejo para que a sucessão ecológica das pilhas de estéril não seja comprometida.

Urban agriculture has its history tied to the development of civilizations. Aiming to identify the benefits generated by the practice and its motivations, a literature review and later analysis of articles describing current experiences, management characteristics and organization aspects was carried out. In countries with a very high HDI, community gardens and the well-being of the population are prominent themes. Countries with high HDI focus on soil contamination and mitigation of pollution impacts, as countries with an average HDI has as main theme the sustainability of the practice. Finally, low HDI countries discuss their importance for food security. Regardless of the objectives that motivate urban agriculture and research in the area, is evidenced its contribution to the environmental, social and economic quality of cities.

O uso inadequado dos solos pode provocar erosão e assoreamento dos cursos d’água reduzindo assim a quantidade e a qualidade da água na bacia. A implantação de práticas conservacionistas de solo e a presença de vegetação nativa são ações de fundamental importância para a conservação do solo e água na bacia, uma vez que elas atuam diminuindo o escoamento superfcial da água e os processos erosivos. Dessa forma, este estudo teve como objetivo desenvolver um mapa de áreas prioritárias para conservação do solo e da água na bacia hidrográfca do Itanguá, Capão Bonito - SP, com base na caracterização do uso e cobertura do solo e declive da bacia e defnir áreas com alta necessidade de implementação de práticas de conservação. Para a elaboração dos mapas temáticos, os planos de informação de uso e cobertura da terra e declividade do terreno foram combinados pelo método booleano em um sistema de informação geográfca. A partir da análise dos dados foram encontradas nove diferentes classes de prioridade para implantação de práticas conservacionistas e seis classes de prioridade para a restauração florestal na área de preservação permanente. Áreas com estrada de terra em região de maior declividade foram identifcadas como áreas prioritárias para conservação, inclusive em área de preservação permanente ao longo dos cursos d’água da bacia. O estudo proporciona a primeira avaliação do uso e cobertura da terra no nível da bacia para a Floresta Nacional de Capão Bonito e fornece uma base para identifcar prioridades de conservação em toda a bacia de Itanguá.

The aim of this investigative research is to identify urban-area springs and propose an Index of Environmental Impact of Springs (IIAN) to support the evaluation of spring conservation. The study area for the project was Ribeirão do Lajeado watershed, located in Sorocaba, SP, Brazil; in which urban-area springs were located and classified according to: type, physical characteristics and vegetation surrounding the spring. Macroscopic diagnosis at each spring location was conducted. Following analysis of samples, results highlighted that all spring sites are impacted negatively by urbanization—with quantity of garbage, protection of the spring area and proximity to urban structures highlighted as key issues. Having collated results and demonstrated existing challenges, findings can be further utilized to support the decision-making process to promote appropriate management and conservation of urban-area springs.

Este trabalho teve como objetivo contribuir para o entendimento da dinâmica dos recursos hídricos na bacia do rio Sorocaba e estabelecer relações entre a disponibilidade e as demandas, fornecendo subsídios para a tomada de ações dos órgãos gestores. A disponibilidade hídrica foi calculada adotando-se a Q95% do tempo na série estudada no exutório da bacia. As vazões das demandas consuntivas foram obtidas com base nos dados dos processos de outorga e diferentes metodologias. Foram calculadas as demandas para o abastecimento humano (urbano e rural), dessedentação animal, industrial e irrigação. As demandas foram estimadas em 11,86 m3.s-1, sendo a maior vazão destinada ao abastecimento humano (6,20 m3.s-1), seguida pela irrigação (3,59 m3.s-1) e industrial (1,83 m3.s-1), corroborando com as características urbanas e industriais da bacia. A demanda atual na bacia corresponde a 49% da disponibilidade hídrica baseada. Essa relação entre oferta e demanda aponta que a bacia encontra-se em situação muito crítica referente ao uso dos recursos hídricos, com potencial para a ocorrência de conflitos. E essa condição tende a piorar caso sejam consideradas as questões referentes à qualidade da água, a qual não foi objeto desse estudo, e que certamente restringiria a disponibilidade para determinados usos.

In order to contribute to the discussion on how forest development interacts with hydrological processes related to rainfall partitioning, we aimed to characterize the rainfall interception (RI), throughfall (Tf), stemflow (Sf), and net precipitation (NP) in three Cerrado areas at different stages of natural regeneration conduction: treatment 1 = area with 4 years without human intervention; treatment 2 = 10 years; and treatment 3 = 43 years. In all areas, three 400-m2 plots were established, in each of which 12 rain gauges and stemflow collectors were installed on all trees having Diameter at Breast High (DBH) > 5 cm. Data was recorded from December 2015 through November 2016. At treatment 1, Tf corresponded to 100% of gross precipitation (GP) in the micro-basin, while Sf corresponded to 0.01%, RI to 0%, and NP to 100% of GP. At treatment 2, Tf corresponded to 96% of GP, whereas Sf corresponded to 0.19%, RI to 4%, and NP to 96% of GP. At treatment 3, Tf corresponded to 87% of GP, while Sf corresponded to 1.15%, RI to 12%, and NP to 88%. The results revealed significant differences among the study areas. Both RI and Sf increased with advancing natural regeneration, while Tf and NP decreased. Data varied according to vegetation features, like the number and density of individuals and species in each plot, and according to characteristics related to weather and precipitation in the area.

Several studies have been conducted aiming to explore the commercial potential of the macaúba palm. However, research on the hydrological processes of this crop are scarce. Thus, we aimed to quantify the surface runoff in a macaúba plantation subjected to different crop management techniques, from September 2012 toAugust 2013. We established 10 plots for surface runoff quantification; each plot had a 63-m² area, was delimited by metallic foils and had a gallon to collect runoff water at its outlet. Plots consisted of three treatments and three repetitions, plus one control plot, each having four macaúba plants. Treatments were as follows: treatment one (T1) - with no soil conservation technique being implemented; treatment two (T2) - with a narrow-base terrace 40 cm wide and 30 cm deep; treatment three (T3) - with bean being planted during the rainy months, forming vegetation strips; and control treatment (T0) - with no macaúba plants, with spontaneous vegetation growing throughout the entire plot and with no soil conservation technique being implemented. Surface runoff differed among treatments. T2 was the treatment with lowest runoff and also the one that demanded the highest precipitation volume for surface runoff to occur. Our results indicate that both the cover and the use of soil conservation techniques are closely related to surface runoff, which in turn affects the occurrence of erosion and infiltration.

This study aimed to evaluate the dynamics of the physical and chemical recovery of the substrates of waste dumps of different ages undergoing natural regeneration, in a calcary mining in Salto de Pirapora - SP, Brazil. Characterization of the vegetation, vegetation and physical and chemical cover of the substrates of the abandoned waste dumps since 1994 and 2013 and the soil of a native forest fragment adjacent to the mining was carried out. Twelve plots of 10x10m were allocated in each environment. It was verified that the soil cover rate with herbaceous, grassy, regenerating and litter of the sterile stacks are similar to the native forest fragment. The same was observed for the physical characterization of soil resistance to penetration, soil moisture content and relative light index. For the chemical characteristics, in all areas sampled there is aluminum deficiency which, consequently, presented low potential acidity and alkaline pH. The CEC of the substrates of the waste dumps presented values similar to the CEC of the native forest fragment, with abundance in some essential nutrients, indicating the possibility of vegetation development in the sterile stacks and the contribution of the natural regeneration to the substrates. Thus, the plant-soil relationship via natural regeneration in the sterile piles contributed to the improvement of the edaphic quality of the substrates over time, being a potential form of recovery in calcary mining. Thereby, the Fabaceae predominated on the waste dumps, especially Leucaena leucocephala, which, despite being an exotic species, is relevant for the current recovery stage of the substrates.

Although the effects of land use changes on hydrological functioning are widely addressed, issues such as which components of the hydrological system are affected, how and on what time scales are still poorly understood. In this context, we evaluated whether forest restoration improves soil water conditions in a Cerrado area, and whether the combined effects of forest structure and hydrological variables influence soil attributes. For this, we monitored three areas in different stages of natural succession over seven months, and evaluated vegetation structure indicators, hydrological indicators and soil indicators. Vegetation structure variables were analyzed with Principal Components Analysis, and to evaluate the direct and indirect effects among the variables we used structural equations modelling. Each successional stage differed in relation to forest structure, affecting the hydrological processes and causing the improvement of soil attributes with forest development. In the initial stage, throughfall was higher due to the more open vegetation, and the soil was more resistant to penetration. With the development of the vegetation, stemflow and interception also increased. As a result of the structural and hydrological changes, the model indicated that soil moisture was influenced directly by throughfall and stemflow, as well as by soil resistance to penetration and infiltration rates, and indirectly by forest structure, which influenced these variables, except infiltration rates. These results suggest that hydrological variables can be good indicators of forest restoration monitoring, providing a direct link to changes in soil conditions.

Springs consist of an upwelling of groundwater from which water flows. This water then forms the drainage network. The negative environmental impacts caused in any portion of the basin may affect the quantity and quality of water. This study characterized the springs of Itanguá watershed, Capão Bonito, SP, considering their types, their conservation status, and the presence of negative environmental impacts. As for the type, springs were classified as “point” or “diffuse” and, regarding conservation status, they were ranked as “excellent”, “good”, “fair”, “bad” and “very bad” based on macroscopic evaluation. Nineteen springs were identified and 15 visited; of these, nine were classified as “point”, and six as “diffuse.” With respect to conservation status, two springs were classified as “excellent”, 12 as “good”, and one as “fair”. The presence of exotic species was observed by macroscopic evaluation, such as animal (boar) and vegetation (Pinus spp.). The lack of vegetation in “permanent preservation areas” was the most frequently observed environmental impact found. The methods used were efficient as a first analysis of the situation of the springs and to provide information to support programs to improve water conservation in the Floresta Nacional de Capão Bonito, SP.
