Soybean-Nodulating Rhizobia: Ecology, Characterization, Diversity, and Growth Promoting Functions
(Frontiers in Sustainable Food Systems, 2022-04-14)The worldwide increase in population continues to threaten the sustainability of agricultural systems since agricultural output must be optimized to meet the global rise in food demand. Sub-Saharan Africa (SSA) is among ... -
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 ... -
Building sustainable societies through vertical soilless farming: A cost-effectiveness analysis on a small-scale non-greenhouse hydroponic system
(Elsevier, 2022-08)The growing rate of population and urbanization among African cities versus the reducing arable land has roused curiosity in soilless farming as an urban farming method to enhance food security and urban sustainability. ... -
Field Margin Plants Support Natural Enemies in Sub-Saharan Africa Smallholder Common Bean Farming Systems
(MDPI, 2022-03-28)Flower-rich field margins provide habitats and food resources for natural enemies of pests (NEs), but their potential, particularly in the tropics and on smallholder farms, is poorly understood. We surveyed field margins ... -
The diversity of aphid parasitoids in East Africa and implications for biological control
(Wiley Online Library, 2021-11-18)BACKGROUND Hymenopteran parasitoids provide key natural pest regulation services and are reared commercially as biological control agents. Therefore, understanding parasitoid community composition in natural populations ... -
