To investigate the impact of land-use on chemical water quality in the Mongolian Kharaa River Basin, the whole catchment and sub-catchments in relation to each sampling point were delineated. Chemical water quality over three seasons was assessed with GIS and RDA in a modeling approach with forward selection of variables and cluster analysis. The most powerful predictors of river water quality were altitude, settlements, forest, cropland, and distance to spring. In particular, this was true when instead of full sub-basins riparian buffer zones (max. 3 km) were considered. From a management perspective, this implies that the protection of riparian zones should be a priority in the Kharaa basin and similar river basins in Mongolia and Central Asia. Because of its positive effects on water quality, forest protection should be closely coupled with river basin management."],["dc.identifier.doi","10.1007/s13280-018-1123-y"],["dc.identifier.pmid","30474831"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/65062"],["dc.language.iso","en"],["dc.relation.eissn","1654-7209"],["dc.relation.issn","0044-7447"],["dc.title","Development and application of GIS-based assessment of land-use impacts on water quality: A case study of the Kharaa River Basin"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dspace.entity.type","Publication"]]

This study aimed to determine—through direct field observations—the influence of air temperature on the frequencies of children´s water contacts with respect to human schistosomiasis transmission risk in the Sourou Valley, located in the North-western part of Burkina Faso. The objectives of the study were: (i) to study the air temperature at which children have the sensation of heat and start looking for water as a means for natural cooling; and (ii) to study whether high frequencies of swimming or bathing may lead to a higher risks of schistosomiasis transmission. To do so, swimming or bathing were observed during two different periods: a cold one from 3rd January to 2nd February 2011 and a hot one from 3rd April to 3rd May 2011 in Toma-Île, a village totally surrounded by water. The results showed that daily mean air temperatures never exceeded 30 °C during the coldest period, while they were above this value during the hottest period. In total, swimming activities were observed 11/31 days during the coldest period and 31/31 during the hottest period. Bathing of children below the age of 5 years occurred on 55/62 days. 25 °C was the day mean air temperature from which children felt hot and began playing in water. The hourly occurrence of swimming and bathing showed peaks at 2 PM. This coincides with the diurnal maximum of infective cercariae present in the same water. Thus, in order to freshen up during hot periods of the day, children used to look for freshwater and thus expose themselves to a high schistosomiasis transmission risk."],["dc.identifier.doi","10.1007/s00477-016-1214-x"],["dc.identifier.scopus","2-s2.0-84955275205"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/64963"],["dc.identifier.url","http://www.scopus.com/inward/record.url?eid=2-s2.0-84955275205&partnerID=MN8TOARS"],["dc.language.iso","en"],["dc.relation.eissn","1436-3259"],["dc.relation.issn","1436-3240"],["dc.title","Influence of air temperature on children water contacts with respect to schistosomiasis transmission risk in the Sourou Valley, Burkina Faso"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dspace.entity.type","Publication"]]

It covers a region that is highly diverse, ranging from almost virgin mountain zones to densely urbanized areas and mining zones. These contrasts have a strong impact on rivers and their ecosystems. Based on two sampling campaigns (summer 2014, spring 2015), we investigated the longitudinal water quality pattern along the Selenga and its tributaries in Mongolia. While headwater regions typically had a very good water quality status, wastewater from urban areas and impacts from mining were found to be main pollution sources in the tributaries. The highest nutrient concentrations in the catchment were found in Tuul River, and severely elevated concentrations of trace elements (As, Cd, Cu, Cr, Fe, Mn, Ni, Pb, Zn), nutrients (NH4+, NO2-, NO3-, PO43-), and selected major ions (SO42-) were found in main tributaries of Selenga River. Moreover, trace element concentrations during spring 2015 (a time when many mines had not yet started operation) were markedly lower than in summer 2014, indicating that the additional metal loads measured in summer 2014 were related to mining activities. Nevertheless, all taken water samples in 2014 and 2015 from the main channel of the Mongolian Selenga River complied with the Mongolian standard (MNS 1998) for the investigated parameters."],["dc.identifier.doi","10.1007/s10661-017-6123-z"],["dc.identifier.pmid","28755155"],["dc.identifier.scopus","2-s2.0-85026812218"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/64959"],["dc.identifier.url","http://www.scopus.com/inward/record.url?eid=2-s2.0-85026812218&partnerID=MN8TOARS"],["dc.language.iso","en"],["dc.relation.eissn","1573-2959"],["dc.relation.issn","0167-6369"],["dc.title","Chemical water quality gradients in the Mongolian sub-catchments of the Selenga River basin"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dspace.entity.type","Publication"]]
