Analysis of spatio-temporal climate variability of a shallow lake catchment in Tanzania
Nyembo, Latifa O.; Larbi, Isaac; Rwiza, Mwemezi J. (IWA Publishing, 2020-04-06)This study analyzed the trends and spatio-temporal variability in rainfall and temperature, and the length of the rainy season (LRS) in the Lake Manyara catchment, Tanzania, covering a period between 1988 and 2018 using ... -
Assessing Land Use/Cover dynamics of the Ngorongoro world heritage site in Tanzania using a hybrid CA–Markov model
Mwabumba, Mohamed; Yadav, BK; Rwiza, Mwemezi J.; Twisa, Sekela; Larbi, Isaac (Authorea, 2020-10)In this study, land-use/cover pattern of the UNESCO world heritage site, Ngorongoro Conservation Area; is analyzed using the CA–Markov model with the help of RS and GIS. Hybrid classification techniques ware used to monitor ... -
Influence of land use change on nitrate sources and pollutant enrichment in surface and groundwater of a growing urban area in Tanzania
Mallya, Clarah L.; Rwiza, Mwemezi J. (Springer Nature Switzerland AG., 2021-01-31)In the present study, 3-year (1997, 2008 and 2017) satellite images as well as different hydro-chemical parameters, nitrogen and oxygen isotopic composition of nitrate were used to examine the impacts of land use and land ... -
