ABSTRACT Lack of access to safe drinking water is a major concern due to negative health effects experienced by people in many parts of the world. The quality of such waters is mainly affected by pollutants from natural and anthropogenic sources when they get incorporated in the water sources. These pollutants are either organic or inorganic species. Among the inorganic pollutants are fluorides. Continuous consumption of high concentrations of fluoride ions leads to their accumulation in th...
ABSTRACT The limitations of conventional technology development gave birth to Farming Systems Research perspective which look at farming practices from a holistic view. This however has innate flaws in its implementation. Recent emphasis therefore is strengthening the need to appreciate a hitherto neglected indigenous knowledge systems. This indigenous knowledge for instance, has been influencing the indigenous practices associated with small-scale plantain production. Before now Plantain has...
Abstract: Forests play vital role in combating climate change through carbon sequestration in the atmosphere and serving as a carbon sink in the form of carbon pool systems of forest ecosystems. This study was aimed to estimate carbon stock variation along the environmental gradients and its contribution to climate change mitigation in Gara-Muktar forest, Western Hararghe zone, Eastern Ethiopia. A systematic sampling method of thirty- six quadrant plots having a size of 20m x 20m each distri...
ABSTRACT The study focused on evaluating the impact of Microfinance Institutions as a form of rural finance on Smallholder Farming in Mt Darwin district. It explored the different types of Microfinance Institutions present in Mt Darwin and the different services offered, whether the program made any significant impact to Smallholder farming and challenges faced in rolling out such programs. There has been a notion in the development discourse especially by Financial Institutions that it is di...
Abstract/Overview Floods are extreme weather events that occur when water rises to overflow on land that is not normally submerged. Flood is one the major natural disasters affecting man and his environment in Kenya, floods have been declared a National disaster. Budalangi Division, which lies in the floodplains of rivers Nzoia and Yala experiences floods every year. This has resulted in decline in agricultural production. The inhabitants of the division are threatened by food Insecurity ...
This research work was carried out to determine the effects of three organic fertilizers namely: cattle dung, poultry droppings and pig excreta on the growth of fingerlings of clarias gariepinus. A total of 120 fingerlings of average length (15.3+2.10) cm and weight (34.2+8.73)g were used for the study.

Abstract/Overview ABSTRACT: Soil has influenced progression of civilization in many regions because it supports food production. Growth in world population has been met by intensification of soil utilization which in turn has caused diverse changes in physical, biological and chemical properties of soil resource. In Nyakach Sub-county in western Kenya intensified agricultural production and soil degradation have proceeded hand-in-hand. This area portrays a mismatch between agricultural pr...
The impacts of extremely high temperatures on plants, human beings and animals’ health have been studied in several parts of the world. However, extreme events are uncommon and have only attracted attention recently. In this study, extreme temperature behaviour was modelled through the application of extreme value theory using maximum monthly temperatures over a 32 years period. Data on monthly maximum temperature from the Upper East Region were modelled using generalized extreme value (GEV...
ABSTRACT Analytical and finite element models were used to simulate additive cold welding patterning processes. The effects of adhesion, pressure, thin film (layer) thickness and dust particle modulus (between the contacting surfaces) are examined. A simple model is developed and used to determine the contact profiles around impurities between cold-welded thin films. These are computed as a function of adhesion, particle modulus, and layer thickness. The models are shown to provide new insig...
ABSTRACT The study examined Productivity and Efficiency of Maize-based Cropping System Farmers in Hong Local Government Area of Adamawa State, Nigeria. The specific objectives of the study were to describe the socio-economic characteristics of the respondents; identify the various maize-based cropping systems in the area; determine the profitability of maize-based cropping systems in the area; estimate the technical, allocative and economic efficiencies of the famers; determine the optimal p...

ABSTRACT The study examined the dominant frames used to portray dancehall artistes and the rationale for such frames on blogs. This research, through the lens of framing and agenda setting theory, and anchored on a case study design interrogates articles from three purposively selected blogs on two purposively selected dancehall artistes. Findings from the study showed that the selected artistes had been presented in the frames of inspirational, prim, prominence, dissociation, prolific, chari...
ABSTRACT Food production issues have dominated Kenyan Government development planning agenda for decades. Low food production have been experienced especially in areas where cash crops such as sugarcane are grown as it competes for rich agricultural land with food crops. Despite income from sugarcane, some households in Dede Division are still experiencing food shortages. This study assessed the effects of sugarcane farming on food production in Dede Division, Migori County. The specific obje...
ABSTRACT Medicinal plants are rich in a wide variety of bioactive compounds associated with various ailments; including antibacterial activity and some of them have been used worldwide in traditional settings to treat diarrheal diseases. However evidence on safety and efficacy of some of these traditional medicinal plants is lacking, preventing their mainstream use. This study aimed at determining the antibacterial activity of Boscia albitrunca, Ziziphus mucronata, Combretum apiculatum, Sola...
ABSTRACT Objective: The study assessed resource-use efficiency among fish farmers in Owo Local Government Area of Ondo State, Nigeria. Methods: A multi stage sampling technique was used to select 50 fish farmers for the study. Data were collected during 2013 production cycle. Multiple regression analysis was used to determine the effects of variables determining the quantity of fish harvested. Allocative efficiency of resources used in raising fish was determined using marginal value product ...
