Linking Climate Information to Livelihood Strategies through ICTs: the Role of Integrated Sustainable Livelihoods Framework
(University of Nairobi, 2017)In this paper, we propose that an Integrated Sustainable Livelihoods Framework (I-SLF), that mainstreams ICT-driven climate information, provides the ideal means by which such information may be leveraged to ensure sustainable ... -
The carbon footprints of alternative value chains for biomass energy for cooking in Kenya and Tanzania
(University of Nairobi, 2017)Due to its availability and affordability for poorer populations, wood-based biomass energy remains vital in meeting local energy demands – especially for cooking fuel – in many regions of the developing world. However, ... -
Using fuzzy cognitive maps in modelling and representing weather lore for seasonal weather forecasting over east and Southern Africa
(University of Nairobi, 2017)The creation of scientific weather forecasts is troubled by many technological challenges while their utilization is dismal. Consequently, the majority of small-scale farmers in Africa continue to consult weather lore to ... -
Awareness and Prevalence of Mycotoxin Contamination in Selected Nigerian Fermented Foods
(University of Nairobi, 2017)Fermented food samples (n = 191) including maize gruel (ogi), sorghum gruel (ogi-baba), melon seed (ogiri), locust bean (iru) and African oil bean seed (ugba) from Southwest Nigeria were quantified for 23 mycotoxins, ... -
Field evaluation of resistance to aflatoxin accumulation in maize inbred lines in Kenya and South Africa
(University of Nairobi, 2017)Aflatoxin, a carcinogenic toxin, is produced mainly by Aspergillus flavus and Aspergillus parasiticus. Contamination of maize (Zea mays L.) grain by these fungi occurs before harvest, and the easiest strategy to prevent ... -
Susceptibility of locally cultivated groundnut (Arachis hypogaea) varieties to aflatoxin accumulation in Homa Bay County, Kenya
(University of Nairobi, 2017)Groundnut is one of the staple foods in many parts of the world. Due to its high nutrient content, the nuts are liable to colonization by aflatoxigenic fungi and subsequent aflatoxin accumulation. This study was aimed ... -
Mycoflora and mycotoxins in finished fish feed and feed ingredients from smallholder farms in East Africa
(University of Nairobi, 2017)A total of 52 samples of finished fish feeds and ingredients were collected from smallholder farmers in Kenya, Tanzania, Rwanda and Uganda, and analyzed. Culture and molecular techniques were used to identify fungal ... -
Effects of Medicinal Plant Extracts and Photosensitization on Aflatoxin Producing Aspergillus flavus (Raper and Fennell)
(University of Nairobi, 2017)This study was undertaken with an aim of exploring the effectiveness of medicinal plant extracts in the control of aflatoxin production. Antifungal properties, photosensitization, and phytochemical composition of aqueous ... -
Molecular profile of malaria drug resistance markers of Plasmodium falciparum in Suriname
(University of Nairobi, 2017)In Suriname, an artesunate monotherapy therapeutic efficacy trial was recently conducted to evaluate partial artemisinin resistance emerging in Plasmodium falciparum We genotyped the PfK13 propeller domain of P. falciparum ... -
Determining resistance to Fusarium verticillioides and fumonisin accumulation in African maize inbred lines resistant to Aspergillus flavus and aflatoxins
(University of Nairobi, 2017)Fusarium verticillioides and Aspergillus flavus cause Fusarium ear rot (FER) and Aspergillus ear rot (AER) of maize, respectively. Both pathogens are of concern to producers as they reduce grain yield and affect quality. ... -
Histidine-rich protein 2 (pfhrp2) and pfhrp3 gene deletions in Plasmodium falciparum isolates from select sites in Brazil and Bolivia
(University of Nairobi, 2017)More than 80% of available malaria rapid diagnostic tests (RDTs) are based on the detection of histidine-rich protein-2 (PfHRP2) for diagnosis of Plasmodium falciparum malaria. Recent studies have shown the genes that code ... -
Genetic characterisation of plasmodium falciparum isolates with deletion of the PFHRP2 and/or PFHRP3 genes in Colombia: The amazon region, a challenge for Malaria diagnosis and control
(University of Nairobi, 2017)Most Plasmodium falciparum-detecting rapid diagnostic tests (RDTs) target histidine-rich protein 2 (PfHRP2). However, P. falciparumisolates with deletion of the pfhrp2 gene and its homolog gene, pfhrp3, have been detected. ... -
Sex-related differences in hematological parameters and organosomatic indices of oreochromis niloticus exposed to aflatoxin B1 diet
(University of Nairobi, 2017)A 24-week feeding experiment was conducted to assess whether males and females of Oreochromis niloticus exhibit differences in their hematological responses and organosomatic indices to dietary AFB1 contamination. Triplicate ... -
