    Assessing the Long-Term Changes in Selected Meteorological Parameters over the North-Rift, Kenya: A Regional Climatology Perspective
    (Hydrology, 2024-12-03) Makokha, John Wanjala; Masayi, Nelly Nambande; Barasa, Peter; Ikoha, Peters Anselemo; Konje, Martha Muthoni; Mutonyi, Jonathan; Okello, Victor Samuel; Wechuli, Alice Nambiro; Majengo, Collins Otieno; Khamala, Geoffrey Wanjala
    Understanding long-term trends in climatic variables is essential for assessing climate change impacts on regional ecosystems and human livelihoods. A regional analysis of climatic variables over some domains is inevitable due to their geographical location and importance to the agricultural sector. Due to the aforementioned demands, the current study analyzes, trends in precipitation (from Climate Hazards Group InfraRed Precipitation with Station data (CHIRPS)), and minimum and maximum temperatures (from TerraClimate) over the North-Rift region of Kenya for over thirty (30) years using satellite data. The seasonal decomposition analysis was performed for each variable to explore the trends and residual components. The findings by the current study indicate that most counties, have experienced enhance precipitation which corresponds to a declining diurnal temperature from 2019 onwards. The seasonality component reveals repeated patterns or variations occurring at steady intervals within each region's data, hence suggesting a distinct regional seasonal trend in the selected meteorological parameters over time. Basically, all counties have reported a relatively constant variability in both maximum and minimum temperatures during the study period except from 2017 onwards where significant variability in the two properties is recorded. In conclusion, the foregoing results that the selected climatic variables exhibit significant spatiotemporal and interannual variability

    Global information technology infrastructure in addressing the borderless problem of overpopulation
    (Journal of Computer, 2016) Barasa, Samuel; Barasa, Peter; Motochi, Vincent; Wabwoba, Franklin
    The world has been beset with fears of future global overpopulation overwhelming the earth’s ecological system and producing shortages of energy, resources, water and food. The sustainability has been a major long-term concern, climate change is thought to be causing a warming of the planet, an increased incidence of extreme weather events, a reduction in agricultural yields, melting the ice caps, and rising sea levels which will eventually cause flooding of low lying islands and coastal districts. As a result, there is dire need for population checks in the world. The causes of overpopulation are attributed to cultural beliefs, lack of sex and population education, religious beliefs etc. The effects of overpopulation include mass poverty, increased death rate, unemployment, etc. It becomes eminent that some measures should be put in place to address this global issue. Some past measures included equipping and funding public and special libraries to disseminate population control information. However, this has not impacted positively in addressing this menace. As a result, the paper purpose to use the global information technology infrastructure in collecting and disseminating information on population control to the masses. This shall be achieved by examining the causes and severity of overpopulation and efforts of addressing them globally, assessing the global information technology infrastructure readiness, stating the ways in which ICTs can be used to control population globally, and making policy recommendations based on the findings of this study. This will be accomplished by content analysis design with continents as the target population. Stratified sampling technique will be used to select the region in each continent. Descriptive analysis will be employed. This paper will help world demographers and population experts advocate population control. Recommendations to all countries to fund and equip telecentres, knowledgebase systems, and Geographical Information Systems are made to address this problem.

    Trends in green computing paradigms towards environment, eco friendly technology and future sustainable Kenya
    (2017-07) Barasa, Peter; Barasa, Samuel; Kimia, Joseph; Motochi, Vincent
    Computing has led to an increase in energy consumption, global warming and e-waste. The environmental impact of computing is alarming, hence the dire need for green initiatives by governments and organizations towards sustainable future. There are various approaches and assumptions of green IT solutions and energy efficient practices in computing. In the paper carries out a systematic study on several strategies and developments in context to the ICT sustainability as a future asset of growth for modern Kenya with special emphasize on the technologies and practices (economic, social, environmental) for creating eco-friendly technology. The paper also highlights trends in green computing paradigms that are used in Kenya for sustainability of the environment. This is achieved by identifying the state of the art technologies and establishing its impact on environmental sustainability using desktop review shall be used on a global perspective.
