Background: Many children under the age of five are exposed to environmental health risks in home environment. These lead diseases such as diarrhoea, which along with acute respiratory infections, malaria and intestinal worms, account for 70% total burden Kenya. The aim this study was investigate whether earth eating within environment by is a risk factor diarrhoeal disease. Methodology: A longitudinal conducted 350 households having aged below years between April October, 2005....
Abstract A study was conducted in the upper reaches of River Njoro watershed to test impacts changing land‐use patterns, from predominantly forest pasture and agriculture, on benthic macroinvertebrate communities. Stream sampling sites were chosen correspond main offstream land uses, including forests, grazing, small‐scale intensive agriculture. Physicochemical variables measured at each site, collected water samples. Sampled macroinvertebrates identified, taxon diversity, richness, evenness...
<span lang="EN-US">Students in secondary schools Rwanda manifest difficulties learning science subjects including biology. Studies revealed that inadequate teaching methods dominated by teacher-centered traditional or conventional educational strategies are some of the factors cause learning, which turn leads to poor achievements This study investigated effect inquiry-based (IBL) using 5Es instructional model (Engage, Explore, Explain, Elaborate and Evaluate) on school students’...
Abstract Data from 10 sampling sites along the River Njoro are used to examine contribution of nutrients upstream land uses draining each sites. The data also assess whether both proportion and size subwatersheds account for variability in water quality watershed. Geographical Information System analysis was determine spatial distribution land‐cover types contributing run‐off Njoro. Standard Digital Elevation Model‐based routines were establish watershed area site. Water sediment samples...
Abstract Spatial and seasonal variations of phytoplankton, expressed in terms species composition, cell density, biovolumes biomass, collected at 10 sampling sites alkaline–saline Lake Nakuru, Kenya, were investigated monthly from March 2004 to February 2005, relation selected physical chemical water quality parameters. A total eight species, belonging five genera three classes, recorded. The Cyanophyceae comprised the bulk followed by Euglenophyceae, while Bacillariophyceae least abundant....
Adoption of improved maize production practices among small scale farmers is essential for increased and consequently food security, poverty alleviation growth in Kenya's economy. This because contribute to 70% the produced country. The ability willingness these adopt may have been affected by introduction agricultural reforms which stemmed from Structural Adjustment Programmes resulting cut backs government expenditure. placed a greater economic burden on farmers. purpose this study...
Abstract This study investigated the relationships between land use, habitat quality, physicochemical water quality and fish assemblage in Sironko River catchment, a tropical mountain stream flowing into Lake Kyoga asin Eastern Uganda. The was carried out at different use sampling sites (natural forest, pastureland, plantation mixed agriculture, banana plantation, urban sugarcane plantation) for 6 months from November 2019 to April 2020. score (HQS) ranged 49% area 75% natural forest. There...
The national maize production levels in Kenya have been declining from an all time high of over 34 million bags to about 25 the years. situation is made worse by agricultural reforms which affected small scale farmers Western Province, one Kenya's food baskets. This paper therefore addresses challenges facing Province reform era. Two hundred were selected through systematic sampling Lugari, Bungoma, Mt. Elgon and Busia districts purposively selected. In addition extension staff was sampling....
The current study investigated the relationship between sediment grain sizes and macroinvertebrate distribution along Isiukhu River, a tropical stream in western Kenya. Ten sites total were selected from upstream, midstream downstream areas. Sampling of sediments macroinvertebrates was carried out twice month March 2018 to 2019. Sediment characterised as polymodal extremely poorly sorted at upstream; trimodal midstream; towards river. Upstream fine gravelly mud very coarse mud, while muddy...
Abstract The dominance of cyanobacterial algae in light‐limited, shallow freshwater Lake Baringo is a major environmental concern regard to Kenyan water quality and public health protection agencies. Accordingly, this study focused on determining the effect different factors cyanobacteria dynamics sediment disturbance zones lake seasons. This also sought bridge knowledge gap regarding influence clarity lake. Samples were collected from field, stored ice transported laboratory for nutrient...
Biology is a core and required science subject offered at the upper secondary school level in Nigerian educational system. However, students’ attitude towards poor, trend probably due to use of teacher-centred strategies. Scholars have thus advocated for need adopt innovative strategies enhance biology. This study investigated consensus cooperative reflective journal writing enhancing attitudes biology two Local Government Areas (LGAs) within Ibadan Metropolis Oyo State, Nigeria. The adopted...
The Njoro Watershed, typical of the semi-arid basins in Rift Valley Kenya, is undergoing a new phase rapid land use change uplands portion watershed, and on-going significant growth both rural urban populations. Considerable negative environmental impacts are occurring, particular to quantity quality river water. Domestic, livestock, commercial, industrial, institutional water users basin affected, as well important downstream habitat Lake Nakuru, large shallow saline lake designated Ramsar...
