Delineation of aquatic plants and estimation of its surface extent are crucial to the efficient control of its proliferation, and this information can be derived accurately with fine resolution remote sensing products. However, small swath and low observation frequency associated with them may be prohibitive for application to large water bodies with rapid proliferation and dynamic floating aqu...

We investigated the phytoplankton species composition and abundance in two seasons Mwanza Gulf, Lake Victoria (Tanzania). Phytoplankton was sampled chlorophyll a content measured dry wet of 2010–2011 at three stations, from southern land-inward end Gulf towards open lake. Cyanobacteria, mostly small colonial filamentous (e.g., Aphanocapsa spp., Planktolyngbya Merismopedia spp.) dominated each s...

In northern Tanzania large numbers of small scale miners use mercury in the gold extraction process causing contamination of the environment and risks to human health. Human exposure to Hg was assessed in populations in and around small scale gold mining camps by means of human hair and urine surveys. We also determined Hg concentration in fish in aquatic bodies close to these camps. Urinary Hg...

The objective of this study was to carry out a community survey on schistosomiais and soil-transmitted helminth (STH) infections in order to suggest feasible and effective intervention strategies in Lake Victoria basin, Tanzania. A total of 37 communities selected from 23 districts of the 4 regions in the Lake Victoria basin of Tanzania were involved in the study. From each of the selected loca...

Water level fluctuations are important modulators of speciation processes in tropical lakes, in that they temporarily form or break down barriers to gene flow among adjacent populations and/or incipient species. Time estimates of the most recent major lowstands of the three African Great Lakes are thus crucial to infer the relative timescales of explosive speciation events in cichlid species fl...

The lake–land breeze circulation over Lake Victoria was observed in unprecedented detail with a research aircraft during the HyVic pilot flight campaign January 2019. An evening and morning lake land breezes respectively under mostly dry conditions. at various heights along transect across onshore Tanzania. Profiles of lower troposphere were recorded by dropsondes land. Convection-permitting Me...
