Assessment of land-use and land-cover (LULC) change any region is one the prominent features used in environmental resource management its overall sustainable development. This study analyzed LULC changes Ngorongoro Conservation Area (NCA) surroundings using Remote Sensing Geographical Information System integrated with Cellular Automata-Markov model. The maps for years 1995, 2005, 2016 were classified unsupervised supervised classification procedure, projected 2025 2035 under...
Land-use/land-cover changes are considered the dominant form of anthropogenic pressure on environment, causing in ecosystem service patterns and affecting water supply services. Using spatial econometric technique, we analysed impact land-use/land-cover change services for domestic use upstream downstream Wami River Basin. The results terms classes during study period (2011–2016) indicate that cultivated land showed maximum positive both sub-catchments, while bushland woodland negative...
Considering the high vulnerability of Northern Tanzania to climate change, an in-depth assessment at local scale is required urgently formulate sustainable adaptations measures. Therefore, this study analyzed future (2021-2050) changes in rainfall and temperature under representative concentration pathways (RCP4.5 RCP8.5) for watersheds surrounding Ngorongoro Conservation Area (NCA) a spatio-temporal relative observed historical (1982-2011) period. The change analysis was performed monthly...
Groundwater account for about 60 to 80% of water supply the population Tanzania's semi-arid regions domestic and agriculture uses. Despite importance groundwater resource in areas, limited information exists on recharge amount potential zones Tanzania context climate change which could result unsustainable withdrawals. This study aimed estimate impact identify Lake Manyara catchment using Water Energy Transfer between Soil, Plants Atmosphere under quasi-steady State (WetSpass) model. The...
Dar es Salaam, like other cities in Africa, experiences flash floods during the rainfall season that destroy infrastructure due to overflow of rivers and blocked sewage. This study investigates historical future variability changes spatial temporal over Salaam. Station data Climate Hazards Group Infrared Precipitation with Stations (CHIRPS) gridded crossing 38 years (1982–2019) were used as a baseline Coordinated Regional Downscaling Experiment (CORDEX) dataset from 2021 2050 was for...
Understanding the hydrochemical composition of water resources in Ngorongoro Conservation Area (NCA, Dodoma, Tanzania) related to climate variability is essential for sustainable development. Thus, current study used HYDRUS-1D model assess groundwater quality change due leaching hydrochemicals from surface under NCA. This observed that area's had varying contaminants, whereas currently most suitable drinking and domestic purposes. However, it predicted two anions (Cl−1 PO4−3) cations (Na+...
Global croplands, pastures, and human settlements have expanded in recent decades. This is accompanied by large increases energy, water, fertilizer consumption, along with considerable losses of biodiversity. In sub-Saharan Africa, policies are implemented without critical consideration; e.g., agricultural expansions impair ecosystem services. We studied land use/cover the associated rate change for four time epochs, i.e., 1991, 2001, 2011, 2021. employed remote sensing GIS techniques...
Global croplands, pastures, plantations, and human settlement areas have expanded in recent decades, accompanied by large increases energy, water, fertilizer consumption, along with considerable losses of biodiversity. In sub-Saharan Africa, policies are implemented without critical consideration e.g., agricultural expansions impair ecosystem services the several river basins. The current study has studied landuse/cover associated rate change for four-time epochs i.e., 1991, 2001, 2011 2021....
In this study, land-use/cover pattern of the UNESCO world heritage site, Ngorongoro Conservation Area; is analyzed using CA–Markov model with help RS and GIS. Hybrid classification techniques ware used to monitor land use/cover changes, Landsat images for 1995, 2005 2016. The CA-Markov then predict use /cover maps 2025 2035. highest net gain from 1995-2016 observed in cultivated (6.55%), grassland (2.68%), bare (1.82%), bushland (0.48%) built-up area (0.01%), loss found woodland (8.38%),...
