“…Sediment is one of the most prevalent and significant pollutants of streams in southwestern Ethiopia (Adela 2015). Buffer strips are considered to be the best method for improving stream water quality by reducing sediment and the nutrient load in runoff (Mander et al 1997;Weller et al 2011;Guo et al 2015). Several studies have investigated the effectiveness of buffer strips in removing sediment and nutrients (Le Bissonnais et al 2004;Borin et al 2005;Mankin et al 2007).…”

“…Runoff from agricultural fields results in the transport of excess sediments and nutrients to receiving streams (Guo et al 2015;Valle Junior et al 2015), and this has been indicated as a major source of nutrients, causing eutrophication and sedimentation of streams (Adela 2015). Buffer strips, which are permanently vegetated areas adjacent to rivers or streams, can provide an efficient and economical way to reduce agricultural nonpoint source pollution (Mander et al 1997;Weller et al 2011;Guo et al 2015). Several studies have investigated the effectiveness of buffer strips in removing suspended solids, nutrients and pesticides from agricultural overflow (Le Bissonnais et al 2004;Borin et al 2005;Mankin et al 2007).…”

Buffer strips are permanently vegetated areas situated immediately adjacent to streams and provide an efficient and economical way to reduce nutrient loads from agricultural areas, but no studies exist of their effectiveness from the East African highlands. We thus evaluated the sediment filtering capabilities of natural herbaceous buffer strips under tropical highland climatic conditions. Overland flow samples were collected at field edges and at various positions in herbaceous buffers and tested for total suspended sediment, nitrate‐nitrogen and total phosphorus. There was a significant effect (P < 0.05) of distance from field edge on the mean values of nutrients. On average, a 10.0 m herbaceous buffer reduced the total phosphorus by 99%, total suspended sediment by 94% and nitrate‐nitrogen by 85%. Altogether, the results suggest that herbaceous buffer strips are important to include in watershed management in agriculturally dominated tropical highlands in order to control sediment loss, stream siltation and the washout of nutrients.

“…With the development of modern society, land-use has undergone continuous changes, which have further affected changes in the local weather and the exchange of energy, momentum, and moisture between land and air [1][2][3]. Human activities have also altered the natural vegetation, causing changes in heat, momentum, and water vapor exchange between the surface and the free atmosphere and affecting the weather and climate, thus affecting the migration and transformation of pollutants in the atmosphere [4][5][6].…”

The expansion of urban areas and the increase in the number of buildings and urbanization characteristics, such as roads, affect the meteorological environment in urban areas, resulting in weakened pollutant dispersion. First, this paper uses GIS (geographic information system) spatial analysis technology and landscape ecology analysis methods to analyze the dynamic changes in land cover and landscape patterns in Chengdu as a result of urban development. Second, the most appropriate WRF (Weather Research and Forecasting) model parameterization scheme is selected and screened. Land-use data from different development stages in the city are included in the model, and the wind speed and temperature results simulated using new and old land-use data (1980 and 2015) are evaluated and compared. Finally, the results of the numerical simulations by the WRF-Chem air quality model using new and old land-use data are coupled with 0.25 • × 0.25 • -resolution MEIC (Multi-resolution Emission Inventory for China) emission source data from Tsinghua University. The results of the sensitivity experiments using the WRF-Chem model for the city under different development conditions and during different periods are discussed. The meteorological conditions and pollution sources remained unchanged as the land-use data changed, which revealed the impact of urban land-use changes on the simulation results of PM 2.5 atmospheric pollutants. The results show the following. (1) From 1980 to 2015, the land-use changes in Chengdu were obvious, and cultivated land exhibited the greatest changes, followed by forestland. Under the influence of urban land-use dynamics and human activities, both the richness and evenness of the landscape in Chengdu increased.(2) The microphysical scheme WSM3 (WRF Single-Moment 3 class) and land-surface scheme SLAB (5-layer diffusion scheme) were the most suitable for simulating temperatures and wind speeds in the WRF model. The wind speed and temperature simulation results using the 2015 land-use data were better than those using the 1980 land-use data when assessed according to the coincidence index and correlation coefficient. (3) The WRF-Chem simulation results obtained for PM 2.5 using the 2015 land-use data were better than those obtained using the 1980 land-use data in terms of the correlation coefficient and standard deviation. The concentration of PM 2.5 in urban areas was higher than that in the suburbs, and the concentration of PM 2.5 was lower on Longquan Mountain in Chengdu than in the surrounding areas.

“…Além disso, o aumento do transporte de sedimentos para os corpos d'água pode levar ao assoreamento do corpo hídrico (MOURI; TAKIZAWA; OKI, 2011).Dentre os processos de degradação do solo verificados em zonas ripárias após a ocupação antrópica, a erosão tem sido amplamente pesquisada por ser responsável tanto pelo assoreamento como o aporte de nutrientes e contaminantes aos corpos hídricos. O assoreamento e o aporte de nutrientes e contaminantes implica em perdas de quantidade e qualidade da água em ecossistemas aquáticos(BING et al, 2013;GUO; HAO; LIU, 2015). O planejamento da gestão dessas áreas, visando a conservação de seus serviços ecossistêmicos, requer um estudo da qualidade do solo para auxiliar na seleção de medidas adequadas para o manejo e a recuperação do solo nas zonas ripárias.A qualidade do solo é definida como a capacidade do solo funcionar e promover a produtividade vegetal e animal e manter ou melhorar a qualidade do ar e da água (DORAN;PARKIN, 1994).…”
