Advances in Amazonian Peatland Discrimination With Multi-Temporal PALSAR Refines Estimates of Peatland Distribution, C Stocks and Deforestation by Bourgeau-Chavez, L.L., Grelik, S.L., Battaglia, M.J., Leisman, D.J., Chimner, R.A., Hribljan, J.A., Lilleskov, E.A., Draper, F.C., Zutta, B.R., Hergoualc'h, Kristell, Bhomia, R.K., Lähteenoja, O.

“…We attribute this improvement in map accuracy over previous maps of the region to the inclusion of high and low water season SAR images which provides information about seasonal hydrological dynamics. The new multi-date map showed an increase in area of more than 200% for pole forest peatland (6% error) compared to previous maps, which had high errors for that ecotype (20–36%). …”

Effects of land cover on ecosystem services in Tanzania: a spatial assessment of soil organic carbon by Winowiecki, Leigh Ann

“…The multiple ecosystem services provided by healthy soil are well known and include soil carbon sequestration to mitigate climate change, a medium for plant and agricultural production and regulating the hydrologic cycle. Despite the wide recognition of the importance of these services, drivers of soil organic carbon (SOC) dynamics across various land uses in East Africa are poorly understood. …”

Escurrimientos Hídricos Superficiales en la Cuenca Hidrográfica de “El Morro”, Provincia de San Luis by Galvan, Mario Jesus, Collado, Alfredo

“…The present situation diagnosis is developed on: a) a qualitative assessment in the field, supported by satellite images and aerial photographs of drainage, climate, landscape, soil, geology and land use / land cover change; and b) a quantitative diagnosis with the application of the hydrological model Watershed and Runnof. The analysis, showed an inapropiated use of land and slopes, with a potential economic and productive downgrading of soil and water resources.…”

Årstidsdynamik för kvicksilver i ett sövattensediment by Karlsson, Anna

“…The lake is not directly affected by any industrial pollution and concentrations of Hg in the sediment reflect the atmospheric deposition in this area, as well as processes taking place along the hydrological pathways from soil to lake. Samples from sediment, bottom- and streamwater were collected in average every second month during the period Feb. – Dec. 2007 at three different locations in the lake. …”
