Soil fertility and land sustainability in Usangu Basin-Tanzania
(Heliyon, 2021-08-09)
Soil fertility determines crop growth, productivity and consequently determines land productivity and sustainability. Continuous crop production exploits plant nutrients from soils leading to plant nutrient imbalance, thus ...
Accumulation and bioconcentration of heavy metals in two phases from agricultural soil to plants in Usangu agroecosystem-Tanzania
(Heliyon, 2021-07-07)
The build-up of heavy metals (HM) in agricultural soils accelerates the HM uptake by plants, which could potentially affect food quality and food safety. Here we studied the status and bioaccumulation of HM from soils to ...
Land use patterns influence the distribution of potentially toxic elements in soils of the Usangu Basin, Tanzania
(Elsevier Ltd., 2021-12)
Spatial distribution of Potentially Toxic Elements (PTEs) in agricultural soils in Usangu Basin (Mbeya Region)-Tanzania were conducted. The study included three land-use types (paddy farming, maize farming, and conserved ...
Cropping patterns along an altitudinal gradient and their implications to wildlife conservation in Rombo, Tanzania
(Elsevier B.V., 2021-08)
Ecosystem and livelihood sustainability of small-scale farmers in Eastern Africa are often challenged by climate change and unsustainable land use practices. Little is known on the small-scale
temporal processes of cropping ...
Characterization of soil phosphate status, sorption and saturation in paddy wetlands in usangu basin-Tanzania
(Elsevier Ltd., 2021-09)
Phosphorus (P) is a vital plant macronutrient required for plant growth which usually available in
limited amount. P availability for plant uptake in highly weathered soil is controlled by soil erosion
and high fixation. ...
We are what we eat, plus some per mill: Using stable isotopes to estimate diet composition in Gyps vultures over space and time
(John Wiley & Sons, Ltd, 2022-02)
1. Dietary studies in birds of prey involve direct observation and examination of
food remains at resting and nesting sites. Although these methods accurately
identify diet in raptors, they are time-consuming, ...
Towards agricultural sustainability: Status and distribution of copper in Usangu agro-ecosystem, Tanzania
(Elsevier, 2022-02-28)
Despite the positive role of copper (Cu) in plants and animals, excessive amounts have environmental and health
effects. Cu has been excessively accumulating in agricultural soils worldwide due to increased agrochemicals ...
A nature‑based approach for managing the invasive weed species Gutenbergia cordifolia for sustainable rangeland management
(SpringerPlus, 2016-10-13)
Background: The invasive weed species Gutenbergia cordifolia has been observed
to suppress native plants and to dominate more than half of the entire crater floor
(250 km2
) in the Ngorongoro Conservation Area (NCA). ...
Physicochemical Properties, Fatty Acid Composition, and the Effect of Heating on the Reduction of Cyclopropenoid Fatty Acids on Baobab (Adansonia digitata L.) Crude Seed Oil
(Hindawi, 2020-12-14)
The baobab seed oil has been consumed by humans due to its medicinal and nutrient values for many years. However, the
consumption of baobab seed oil has been perceived by different communities as a health risk caused by ...
Integrating stakeholders' perspectives and spatial modelling to develop scenarios of future land use and land cover change in northern Tanzania.
(PLOS ONE, 2021-02-12)
Rapid rates of land use and land cover change (LULCC) in eastern Africa and limited instances of genuinely equal partnerships involving scientists, communities and decision makers challenge the development of robust pathways ...
