This study employed Remote Sensing and Geographical Information Systems to explore the influence of environmental factors human-induced land use/land cover changes on chemistry soda-saline lakes in Northern Tanzania. Satellite-based rainfall data were sourced from Climate Hazards Group Infrared Precipitation with Station (CHIRPS) datasets, temperature obtained MERRA-2. Monthly precipitation, temperature, drought conditions lake watersheds analyzed 1981 2022, while use assessed for 2000, 2014, 2023. Soil types acquired FAO Digital Map World, geological characteristics US Geological Survey database. The findings revealed that region's climate is ideal enhancing evapotranspiration, leading mineral altering lakes. Standardized Evapotranspiration Index increased events basins since 1987, prolonged occurrence between 2000 2017. results also showed region characterized by a variety soil types, including ferric acrisols, chromic cambisols, calcic entisols, inceptisols, eutric fluvisols, distric nitisols, humic mollic andosols, ochric pellic vertisols. Furthermore, distinguished diverse processes, Precambrian-Cambrian tertiary intrusive, triggered volcanic tectonic activity.

The changes in landscape structure and functioning due to unprecedented human interference are hastening across the globe it is thus a compelling necessity preserve restore our ecosystems. This study aimed characterize levels of fragmentation, habitat structure, driving forces, perceptions residents on most preferred reconfiguration approaches. land use/land cover [LULC] change was first determined by interpreting 1973, 1986, 1995, 2002, 2014, 2022 Landsat images using QGIS 3.26 while selected fragmentation metrics were analyzed FRAGSTATS 4.2. Forests, shrubs, grasslands showed declining trend, except for agriculture, water, built-up areas, which depicted high increases periods [1973 2022]. area characterized as progressively fragmenting signified escalated values patch number [374 %], edge density [7828 %] between 1986 contagion [10.3%], declined value Shannon Diversity Index [SHDI] [-17.42%], evenness index [SHEI] [-25.8 connectedness [-43.3%]. Considering these results, losses forests coupled with expansive farmlands areas have led From field surveys oral interviews, this has not only left streams vulnerable massive sediment loads but also triggered annual floods occur during wet months even though onset rainfall seasons reported. findings call restoration integrated sustainable efforts, especially forests, grasslands, riparian corridors along urban planning community-based sensitization watershed management.

ABSTRACT The expected influences of climate alteration on hydrological responses in the Gibe Gojeb catchment, southwestern Ethiopia, were evaluated using Soil and Water Assessment Tool (SWAT) model regional models (RCMs). This study emphasizes evaluation change impact responses. RCM data downloaded from CORDEX-Africa. Power transformation delta methods used for bias correction precipitation temperature, respectively. calibration validation SWAT showed good agreement, was simulated. Accordingly, precipitation, soil water content, percolation, yield, groundwater are projected to decrease by 28.18, 7.5, 9.1, 5.4, 9.2%, respectively, under RCP4.5 future (2021–2050). Besides, surface runoff potential actual evapotranspiration increase 17.4, 11.32, 5.06%, 10.51, 5.63, 2.76, 21.57%, RCP8.5 future. Rain-fed crop production hydropower generation catchment would be vulnerable effects change. results help develop effective adaptation measures reduce impacts draft long-term resource management plans catchment.
