Farmers Willingness to Pay and the Sustainability of Irrigated Maize Production in Rural Kenya
(2017-07)This paper evaluated farmers willingness to pay for irrigated maize production using field level data collected through a cross sectional survey. The results showed that 78% of the farmers were willing to pay more than the ... -
Can irrigation be an answer to Kenya’s food security problem?
(2015-10)Irrigation development is one strategy the government can use to improve food security in Kenya. Lessons from irrigated maize production studies show that it is profitable and that Galana Kulalu food security project has ... -
Disentangling farmers’ preferences and cost allocation among inputs for food security in Vihiga District, Kenya
(2011-03)Vihiga, one of the poorest and densely populated districts in Kenya, is perpetually in food deficit. Poor welfare and a low resource base continue to curtail efforts to circumvent food insecurity among households in the ... -
Land access and outmigration in densely populated areas of rural Kenya Land access and outmigration in densely populated areas of rural Kenya
(2021-02)One of the key drivers of youth migration of inequitable distribution of land which denies them access to work environment. Youths hold limited small land sizes even when they migrate and this limits there involvement in ... -
Effect of Varying Thickness on Performance of Titanium Dioxide Solar Cell
(2021-03)The need for energy to drive economic development has increased tremendously yet most energy sources lead to environmental pollution with consequences such as global warming and serious health complications. Global warming ... -

Optimal Battery Location for Minimizing the Total Cost of Generation in a Power System
(2020)Wind is one of the major and fast growing source of green energy in the world. However, it’s naturally variable and this reduces its percentage penetration in a power system because of costs associated with balancing ... -
Voltage Stability Analysis and Improvement of Power System With Increased SCIG-based Wind System Integration
(2020)This paper presents voltage stability analysis and improvement of power system when there is increase in wind power penetration. Loading parameter-Voltage curve was used to calculate the loadability and the megawatt margin ... -
New approach for design shunt active power filter for power quality improvement in a three phase three wire system
(2020)Use of power electronic-based load has increased in the resent decade. These loads draw non-sinusoidal currents and voltages from the utility supply generating harmful harmonics. Injection of harmonic currents and voltages ... -
Key Generation for Electrical Smart Meters using Hash Functions
(2019)The electrical power grid has been undergoing improvements to turn it into a more efficient system known as the Smart Grid. A key element in this upgrade is the Smart Meter. A compromise on the cyber-security of the smart ... -
Under Voltage Load Shedding using Hybrid Metaheuristic Algorithms for Voltage Stability Enhancement: A Review
(2020)Power blackouts are experienced globally, more so with increasing load demand and ageing infrastructure. The high failure rate of conventional and adaptive load shedding techniques is prevalent during multiple contingencies. ... -
Optimal Sizing and Placement of Solar Photovoltaic based DGs in the IEEE 9 bus system using Particle Swarm Optimization Algorithm
(2018)Solar energy is one of the most commonly exploited renewable resource globally. Integration of power from solar to the main grid can either bring positive or negative impact which normally depends on their size and location. ... -
Protection of Terminal Distribution Transformers: A Case Study of Kenya Power
(IEEE, 2018)The paper presents and analyses the main causes of high failure rate of Terminal Distribution Transformers (TDTs) in Kenya. These transformers are the most susceptible to faults emanating from lightning strikes and associated ... -
Power Quality Challenges and Mitigation Measures in Grid Integration of Wind Energy Conversion Systems
(IEEE, 2018)Wind energy generation is a promising renewable energy source harvested through Wind Energy Conversion Systems (WECS). Since WECS have different characteristics from conventional power plants, their integration into the ... -
Implementation of a Structural Complexity Metrics Tool for Sassy Cascading Style Sheets (SCMT-SCSS)
(2020)The development of metrics tool is a basic requirement for the defined software metrics to be acceptable in the software industry. There are several metrics proposed over the years without tool support and this trend cannot ...
