The effect of land-use systems on greenhouse gas production and crop yields in Wakiso District, Uganda
(Elsevier B.V., 2020-12-16)
Land-use systems are among the leading sources of anthropogenic GHG into the atmosphere; driving global warming, climate change, and associated extreme weather events. To estimate GHGs from the land-use systems, we measured ...
Toxic metals in East African agro-ecosystems: Key risks for sustainable food production
(Elsevier B.V., 2021-09-15)
The dramatic increase in world population underpins current escalating food demand, which
requires increased productivity in the available arable land through agricultural intensification.
Agricultural intensification ...
Characterization of land use influence on soil phosphate bioavailability in Usangu agro-ecosystem-Tanzania
(Elsevier B.V., 2021-12)
Phosphorus (P) is an important nutrient required for plant growth. Land use influences concentration and bioavailability of P in agricultural soils. About 198 soil samples (0-30 cm soil depth) were collected from three ...

(MDPI, 2022-06-28)
Habitat condition is a vital ecological attribute in wildlife conservation and management
in protected areas, including the Burunge wildlife management areas in Tanzania. Traditional
techniques, including satellite remote ...
Towards sustainability: Threat of water quality degradation and eutrophication in Usangu agro-ecosystem Tanzania
(Elsevier, 2022-08-01)
The agrochemicals and nutrient losses from farming areas such as paddy farming significantly dictate quality and eutrophication of the freshwater resource. However, how farming and land use pattern affect water qualities ...
Spatial distribution and anthropogenic threats facing medicinal plant Zanthoxylum chalybeum in Simanjiro Area, Northern Tanzania.
(Elsevier, 2020-11)
Knob wood (Zanthoxylum chalybeum - Rutaceae) is a medicinal plant species subject to heavy exploitation throughout its areas of occurrence in Sub-Saharan Africa. Despite that the tree has different values as a traditional ...
Increasing agricultural soil phosphate (P) status influences water P levels in paddy farming areas: Their implication on environmental quality
(Elsevier Ltd., 2022-10-03)
Intensive paddy farming activities involve higher use of irrigation water and agrochemicals to increase crop productivity per unit area. However, a practice may result in environmental challenges due to nutrient loss and ...
Integrating land-water-people connectivity concepts across disciplines for co-design of soil erosion solutions
(John Wiley & Sons, Inc., 2020-10-02)
Soil resources in East Africa are being rapidly depleted by erosion, threatening food, water and livelihood security in the region. Here we demonstrate how the integration of evidence from natural and social sciences has ...
Potentially toxic elements status and distribution in Usangu agroecosystem-Tanzania
(Elsevier, 2021-08)
This study was conducted to highlight status and distribution of potentially toxic elements (PTEs) in Usangu
agroecosystem-Tanzania. The study involved 198 soil samples from 10 irrigation schemes including three land
use. ...
Connectivity between land, water, and people: integrating process concepts and assessment evidence across disciplines for co-design of soil erosion solutions
(Authorea, 2020-04-20)
Soil resources in East Africa are being rapidly depleted by erosion, threatening food-, water- and livelihood security in the region. Here we demonstrate how integration of evidence from natural and social sciences has ...
