O estudo da erosão em regiões semiáridas, principalmente quando o solo e a vegetação tornam-se vulneráveis por meio de atividades antrópicas, sem que haja conservação do ambiente explorado, indica que além do processo erosivo natural, o ambiente erodido pode sofrer um processo de desertificação. Diante desse contexto foi possível observar e analisar a erosão, a vulnerabilidade e os riscos na região do Seridó paraibano, especialmente no município de Juazeirinho, por apresentar uma fisiografia de Caatinga, solo arenoso e baixa pluviosidade, além de apresentar econômica e socialmente, explorações de minérios, sobretudo, da rocha caulim. As proposições metodológicas colocadas no trabalho, às coletas feitas in loco e a ferramenta do SIG contribuiu para apontar indicadores de riscos à erosão tanto do processo natural quanto o antropogênico. Os resultados apontaram uma vulnerabilidade natural média e alta para a região estudada, devido às instabilidades pluviométricas e a condições geomorfológicas da área. O processo erosivo pela ação antrópica mostrou um alto e severo risco à erosão, consequentemente deixando o ambiente propicio à desertificação em que se constatou um valor de 217.686,12km², (46,56%) da área do município, praticamente a metade do mesmo, gerando, portanto, uma preocupação grave pelo empobrecimento do solo e da cobertura vegetal nativa.    A B S T R A C TThe study of erosion in semiarid regions, especially when the soil and vegetation become vulnerable through anthropogenic activities without environmental conservation explored, indicates that besides the natural erosive process, the eroded environment can suffer a process of desertification. In this context it was possible to observe and analyses the erosion, the vulnerability and risks in the Northeast region of Brazil, especially in the municipality of Juazeirinho by presenting a physiography of Caatinga, sandy soil and low rainfall, as well as present economic and socially, holdings of ores, especially, caulim rock. The methodological propositions placed on the work, the collections made on the spot and the GIS tool contributed to point indicators of risks erosion of both the natural process as anthropogenic. The results showed a natural medium and high vulnerability to the region studied, due to rainfall and geomorphologic conditions instability of the area. The erosive process by anthropic action showed a high and severe erosion risk, consequently leaving the environment propitious to desertification in which if found in a value of 217,686.12 Km ², (46.56%) the area of the city, practically half of the same, generating thus a serious concern by the impoverishment of soil and vegetation cover.Keywords: Erosion, vulnerability, Risks, Process of desertification, Mapping.

Heavy metals in road dust pose a significant threat to human health. This study investigated the concentrations, patterns, and sources of eight hazardous heavy metals (Cr, Ni, Cu, Zn, As, Cd, Pb, and Hg) in the street dust of Zhengzhou city of PR China. Fifty-eight samples of road dust were analyzed based on three methods of risk assessment, i.e., Geo-Accumulation Index (Igeo), Potential Ecological Risk Assessment (RI), and Nemerow Synthetic Pollution Index (PIN). The results exhibited higher concentrations of Hg and Cd 14 and 7 times higher than their background values, respectively. Igeo showed the risks of contamination in a range of unpolluted (Cr, Ni) to strongly polluted (Hg and Cd) categories. RI came up with the contamination ranges from low (Cr, Ni, Cu, Zn, As, and Pb) to extreme (Cd and Hg) risk of contamination. The risk of contamination based on PIN was from safe (Cu, As, and Pb) to seriously high (Cd and Hg). The results yielded by PIN indicated the extreme risk of Cd and Hg in the city. Positive Matrix Factorization was used to identify the sources of contamination. Factor 1 (vehicular exhaust), Factor 2 (coal combustion), Factor 3 (metal industry), and Factor 4 (anthropogenic activities), respectively, contributed 14.63%, 35.34%, 36.14%, and 13.87% of total heavy metal pollution. Metal’s presence in the dust is a direct health risk for humans and warrants immediate and effective pollution control and prevention measures in the city.

The air quality of modern cities is considered an important factor for the quality of life of humans and therefore is being safeguarded by various international organizations, concentrating on the mass concentration of particulate matter (PM) with an aerodynamic diameter less than 10, 2.5 and 1 μm. However, the different physical and anthropogenic processes and activities within the city contribute to the rise of fine (<1 μm) and coarse (>1 μm) particles, directly impacting human health and the environment. In order to monitor certain natural and anthropogenic events, suspecting their significant contribution to PM concentrations, seven different events taking place on the coastal front of the city of Limassol (Cyprus) were on-site monitored using a portable PM instrument; these included both natural (e.g., dust event) and anthropogenic (e.g., cement factory, meat festival, tall building construction, tire factory, traffic jam, dust road) emissions taking place in spring and summer periods. The violations of the limits that were noticed were attributed mainly to the various anthropogenic activities taking place on-site, revealing once more the need for further research and continuous monitoring of air quality.

Abstract Erosion processes can strongly influence the dissipation of glyphosate and aminomethylphosphonic acid applied with Roundup Max® in agricultural soils; in addition, the soil structure state shortly before erosive precipitations fall can be a key parameter for the distribution of glyphosate and its metabolite. Field rain simulation experiments showed that severe erosion processes immediately after application of Roundup Max® can lead to serious unexpected glyphosate loss even in soils with a high presumed adsorption like the Cambisols, if their structure is unfavourable. In one of the no-tillage-plot of the Cambisol, up to 47% of the applied glyphosate amount was dissipated with surface run-off. Moreover, at the Chernozem site with high erosion risk and lower adsorption potential, glyphosate could be found in collected percolation water transported far outside the 2x2 m experimental plots. Traces of glyphosate were found also outside the treated agricultural fields.

Anthropogenic activities cause damage to the natural ecosystems in the city in various ways, which contributes to the reduction of biodiversity. Considering that biodiversity is becoming more vulnerable to the impact action triggered by urban activities is necessary to monitor it in order to take urgent measures to protect and preserve it. The plant biodiversity study methodology includes methods that help determine phytocenosis parameters and assess biomass in order to estimate the productive potential of phytocenosis. Carrying out the research according to the proposed methodology will make it possible to assess the anthropogenic impact on the terrestrial and riparian vegetation.

Abstract Background: Soil erosion causes topsoil loss, which decreases fertility in agricultural land. Spatial estimation of soil erosion essential for an agriculture-dependent country like Nepal for developing its control plans. This study evaluated impacts on Dolakha using the Revised Universal Soil Loss Equation (RUSLE) model; analyses the effect of Land Use and Land Cover (LULC) on soil erosion. Results: The soil erosion rate categorized into six classes based on the erosion severity, and 5.01% of the areas found under extreme severe erosion risk (> 80 Mg ha-1yr-1) addressed by decision-makers for reducing its rate and consequences. Followed by 10 % classified between high and severe range from 10 to 80 Mg ha-1yr-1. While 15% and 70% of areas remained in a moderate and low-risk zone, respectively. Result suggests the area of the north-eastern part suffers from a high soil erosion risk due to steep slope. Conclusions: The result produces a spatial distribution of soil erosion over Dolakha, which applied for conservation and management planning processes, at the policy level, by land-use planners and decision-makers.

Trajeto etnográfico realizado em contexto multidisciplinar de pesquisa motiva essa narrativa reflexiva. Recorre-se criticamente a observação participante realizada em dois distritos rurais nas circunvizinhanças da segunda maior cidade gaúcha (Caxias do Sul). O procedimento foi conduzido mediante o acompanhamento do ciclo de louvação da festa do Divino Espírito Santo, mas a narrativa própria, que desvela a paisagem como bem de uso comum no lugar, atinge-se através da atenção às alteridades desveladas nesse percurso. Nesse contexto, avaliam-se as contribuições e possibilidades do fazer etnográfico em um tema mais abrangente ainda a deslindar: a luta dos habitantes do lugar - agricultores há mais de 150 anos nos Campos de Cima da Serra - para continuarem seus projetos de vida. Pois, supostamente no mesmo espaço-tempo, a cidade exige outras ações, sob o discurso da conservação ambiental, contudo portando em seu bojo desejos de outras espécies. Nessa pesquisa de paisagem, mais do que compreender, almeja-se ressoar a voz de quem vive no lugar.Palavras-chave: Paisagem. Ruralidade. Etnografia. The Landscape in Criúva and Vila Seca, Caxias do Sul, Brazil: an ethnographic narrativeAbstractOngoing ethnographic path nested in a multidisciplinary context research, motivates this reflective narrative. The participant observation conducted in two rural districts in the neighborhood of the second largest city of Rio Grandedo Sul (Caxias do Sul) is critically reviewed. The main procedure that was carried out was the following of celebrations cycle of the Holy Spirit. Despite this, the narrative that unfolds the landscape as a common use in the place it is reached through the attention to diversitiesunveiled in this path. In this context, the researchers seek to critically evaluate the contributions and possible contributions of ethnographic work to a more comprehensive theme. The drama to be empirically figured out is the struggles of inhabitants of the place - farmers since 150 years in Campos de Cima da Serra - to continue their life projects. It happens that, supposedly in the same space time, the city requires other actions in the discourse of environmental conservation, however showing desires of other species. In this landscape survey more than to understand, it’s aimed to resonate the voices of people who live in the place.Key words: Landscape. Rurality. Ethnography.
