Human population growth as indicator for human-elephant conflicts in Rombo area, Tanzania
(Journal of Biodiversity and Environmental Sciences (JBES), 2017-04-17)
Conservationists need detailed information on human population growth and distribution in areas adjacent to
protected areas. This information can help determine land use/land cover changes (LULCC), which affect the
quality ...
Drivers of increased soil erosion in East Africa’s agro-pastoral systems: changing interactions between the social, economic and natural domains
(Springer, 2019-06-08)
Increased soil erosion is one of the main drivers of land degradation in East Africa’s agricultural and pastoral landscapes. This wicked problem is rooted in historic disruptions to co-adapted agro-pastoral systems. ...
Emerging issues and challenges associated with conservation of the African baobab (Adansonia digitata L.) in the semi-arid areas of Tanzania
(International Network for Natural Sciences, 2019-11)
The aim of this review is to discuss the emerging issues and challenges in baobab conservation based on the climate change, emerging challenges related to herbivory and human use such as emerging of new markets for baobab ...
Invasive plants: ecological effects, status, management challenges in Tanzania and the way forward
(Journal of Biodiversity and Environmental Sciences (JBES), 2017-03-31)
Over decades invasive plants have been exerting negative pressure on native vascular plant’s and hence devastating
the stability and productivity of the receiving ecosystem. These effects are usually irreversible if ...
Soil erosion in East Africa: an interdisciplinary approach to realising pastoral land management change
(IOP Publishing Ltd, 2018-12-03)
Implementation of socially acceptable and environmentally desirable solutions to soil erosion
challenges is often limited by (1) fundamental gaps between the evidence bases of different disciplines
and (2) an implementation ...
Pinpointing baobab (Adansonia digitata [Linn. 1759]) population hotspots in the semi‐arid areas of Tanzania
(John Wiley & Sons, 2019-11-15)
The impact of unsustainable land‐use conversions, changes in climate and anthropogenic activities on abundance and distribution of baobab populations was assessed in semi‐arid regions of Tanzania. Baobabs were sampled in ...
Potential opportunities and constraints in utilising AVRDC-distributed vegetable seedkit in Arumeru District, Tanzania
(African-American Institute, 2014-05-10)
The vast majority of yield growth in African agriculture to date has been due to improved seed varieties, as opposed to technological improvements in cultivation practices or other inputs. However, the lack of development ...
Variations in Greenhouse Gas Fluxes in Response to Short-Term Changes in Weather Variables at Three Elevation Ranges, Wakiso District, Uganda
(MDPI, 2019-11-14)
Weather conditions are among the major factors leading to the increasing greenhouse gas (GHG) fluxes from the agricultural soils. In this study, variations in the soil GHG fluxes with precipitation and soil temperatures ...
Tracking animal movements using biomarkers in tail hairs: a novel approach for animal geolocating from sulfur isoscapes.
(Movement Ecology, 2020-09-18)
Background
Current animal tracking studies are most often based on the application of external geolocators such as GPS and radio transmitters. While these technologies provide detailed movement data, they are costly to ...
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 ...
