Assessing the Impacts of Land Use and Climate Changes on River Discharge towards Lake Victoria
James, Renatus; Amasi, Aloyce; Wynants, Maarten; Nobert, Joel; Mtei, Kelvin; Njau, Karoli (MDPI, 2023-05-08)The Lake Victoria basin’s expanding population is heavily reliant on rainfall and river flow to meet their water needs, making them extremely vulnerable to changes in climate and land use. To develop adaptation and ... -
Assessment of Potentially Toxic Metals in Fish from Lake Manyara, Northern Tanzania
Sawe, Shovi; Amasi, Aloyce; Wynants, Maarten (Springer US, 2023-09)Elemental tracer concentrations of copper, lead, nickel and zinc, were assessed in the muscles of Oreochromis amphimelas and Clarias gariepinus from Lake Manyara, Tanzania, to evaluate their safety to consumers, specifcally ... -
Building Climate Change Adaptation and Resilience through Soil Organic Carbon Restoration in Sub-Saharan Rural Communities: Challenges and Opportunities
Taylor, Alex; Wynants, Maarten; Kelly, Claire; Mtei, Kelvin; Mkilema, Francis; Ndakidemi, Patrick; Nasseri, Mona; Kalnins, Alice; Patrick, Aloyce; Gilvear, David; Blake, William (MDPI, 2021-10-02)Soil organic carbon (SOC) is widely recognised as pivotal in soil function, exerting important controls on soil structure, moisture retention, nutrient cycling and biodiversity, which in turn underpins a range of provisioning, ... -
Drivers of increased soil erosion in East Africa’s agro-pastoral systems: changing interactions between the social, economic and natural domains
Wynants, Maarten; Kelly, Claire; Mtei, Kelvin; Munishi, Linus; Patrick, Aloyce; Rabinovich, Anna; Nasseri, Mona; Gilvear, David; Roberts, Neil; Boeckx, Pascal; Wilson, Geoff; Blake, William; Ndakidemi, Patrick (Springer Berlin Heidelberg, 19-06-18)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. ... -
Drivers, Impacts and Mitigation of Increased Sedimentation in the Hydropower Reservoirs of East Africa
Amasi, Aloyce; Wynants, Maarten; Mahene, William; Mtei, Kelvin (MDPI, 2021-06-16)Hydropower reservoirs are essential for the climate-neutral development of East Africa. Hydropower production, however, is threatened by human activities that lead to a decrease in water storage capacity of reservoirs. ... -
Evaluating Soil Carbon as a Proxy for Erosion Risk in the Spatio-Temporal Complex Hydropower Catchment in Upper Pangani, Northern Tanzania
Amasi, Aloyce; Wynants, Maarten; Kawala, Remigius; Sawe, Shovi; Blake, William; Mtei, Kelvin (MDPI, 2021-10-15)Land use conversion is generally accompanied by large changes in soil organic carbon (SOC). SOC influences soil erodibility through its broad control on aggregate stability, soil structure and infiltration capacity. ... -
Informing versus generating a discussion: Comparing two approaches to encouraging mitigation of soil erosion among Maasai pastoralists
Rabinovich, Anna; Zhischenko, Vladimir; Nasseri, Mona; Stacey, Heath; Laizer, Alpha; Mkilema, Francis; Patrick, Aloyce; Wynants, Maarten; Blake, William; Mtei, Kelvin; Ndakidemi, Patrick (Elsevier, 2022-10-21)Soil erosion is a critical problem for pastoralist societies that rely on healthy grazing land for their livelihoods. Previous research suggests that unsustainable land management practice is one of the factors exacerbating ... -
Reconstructing the Changes in Sedimentation and Source Provenance in East African Hydropower Reservoirs: A Case Study of Nyumba ya Mungu in Tanzania
Amasi, Aloyce; Wynants, Maarten; Kawalla, Remegius; Sawe, Shovi; Munishi, Linus; Blake, William; Mtei, Kelvin (MDPI, 2021-08-08)This study aimed to reconstruct the sedimentation rates over time and identify the changing sources of sediment in a major hydropower reservoir in Tanzania, the Nyumba ya Mungu (NYM). Fallout 210Pb measurements were used ... -
Soil erosion and sediment transport in Tanzania: Part I – sediment source tracing in three neighbouring river catchments
Wynants, Maarten; Munishi, Linus; Mtei, Kelvin; Bodé, Samuel; Patrick, Aloyce; Taylor, Alex; Gilvear, David; Ndakidemi, Patrick; Blake, William; Boeckx, Pascal (Earth Surface Processes and Landforms, 2021-12)Water bodies in Tanzania are experiencing increased siltation, which is threatening water quality, ecosystem health, and livelihood security in the region. This phenomenon is caused by increasing rates of upstream soil ... -
Soils, Science and Community ActioN (SoilSCAN): a citizen science tool to empower community-led land management change in East Africa
Kelly, Claire; Wynants, Maarten; Patrick, Aloyce; Taylor, Alex; Mkilema, Francis; Nasseri, Mona; Lewin, Shaun; Munishi, Linus; Mtei, Kelvin; Ndakidemi, Patrick; Blake, William (IOPscience, 2022-08-02)Pastoralist communities worldwide face complex challenges regarding food and feed productivity. Primary production systems are under stress, nutritional choices are changing and the relationship between development and ... -
Tracing the dominant sources of sediment flowing towards Lake Victoria using geochemical tracers and a Bayesian mixing model
James, Renatus; Amasi, Aloyce; Wynants, Maarten; Nobert, Joel; Mtei, Kelvin; Njau, Karoli (Springer Nature, 2023-02-14)Purpose Lake Victoria has been increasingly silting over the past decades, impacting water quality and loss of biodiversity. Sediment control strategies require information on the relative and absolute contributions of ...
