Soil erosion and sediment transport in Tanzania: Part I – sediment source tracing in three neighbouring river catchments
(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 ... -
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 ... -
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 ... -
Soilless urban gardening as a post covid-19 food security salvage technology: A study on the physiognomic response of lettuce to hydroponics in Uganda
(Elsevier, 2023-03)This study was conducted to assess the performance of vegetables using a non-greenhouse hydroponic system as a sustainable urban farming technology to increase food security (in terms of vegetable production and availability). ... -
Soils, Science and Community ActioN (SoilSCAN): a citizen science tool to empower community-led land management change in East Africa
(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 ... -
Solar-Drying of Vegetables for Micronutrients Retention and Product Diversification
(American Journal of Research Communication, 2016)Micronutrients retention of solar-dried vegetables were studied with an aim of increasing iron, zinc and β-carotene bioaccessibility as well as product diversification. Iron, zinc and β-carotene contents in fresh and dried ... -
