This study explored the land use and land cover (LULC) changes (1995–2023) in the gold mining hotspots of Mang’onyi, Sambaru, and Londoni in the Singida region of Tanzania. The study integrated remote sensing (RS) to evaluate the LULC transitions with social survey assessments (83 respondents) to determine the resident’s perceptions of the environm...

Although numerous studies have reported an increased yield upon adoption to improved agricultural practices (IAPs), yet smallholder farmers face limited access to this information. The objective of this study was to assess smallholder farmers' awareness and adoption of IAPs. A total of 206 active and registered households were surveyed by mixed sam...

This study employed Remote Sensing and Geographical Information Systems to explore the influence of environmental factors and human-induced land use/land cover changes on the chemistry of soda-saline lakes in Northern Tanzania. Satellite-based rainfall data were sourced from the Climate Hazards Group Infrared Precipitation with Station (CHIRPS) dat...

New hydrological insight of the region: The results revealed that lake water pH ranged from 9.0 to 10.2, EC ranged from 2843 to 109,800 µS/cm, and Na + dominated over other cations with mixed dominance of HCO 3-+ CO 3 2-, Cl-, and SO 4 2-. The study also revealed that lakes Balangida and Balangida Lelu had higher sulphate levels than the other lake...

This study reviews the chemical properties of inland soda-saline lakes of the EARV, classifies lake water chemical types, and assesses the spatial distribution of the major ions. The chemical data were collected from published articles (1968-2022) where the salinity (TDS) exceeded 1 g/l concentration. Based on the total alkalinity and pH, the modif...

Granulated micelle–clay complexes including the organic cation octadecyltrimethylammonium (ODTMA) were shown to be efficient in removal of total bacteria count (TBC) from water. Microwave (MW) heating of granules to restore bacterial removal was investigated. Drying of granules by MW required 20-fold less energy than by conventional heating. When w...
