Knowledge Organization Capability and Competitiveness of Chartered Public Universities in Kenya Gachanja, Joseph Nguru Purpose: Knowledge has increasingly become one of the most critical determining factors for organizational competitiveness. In order to acquire and sustain a competitive advantage, it is vital for an organization to develop effective strategies that foster knowledge creation, transfer and integration in the performance of the organization. Knowledge organization refers to activities such as document description, indexing, and classification that provide systems of representation and order for information and knowledge materials. The purpose of this study was to establish the relationship between knowledge organization capability and competitiveness of chartered public universities in Kenya. Methodology: The study adopted a descriptive design. The population of the research consisted of 31 chartered public universities authorized to operate in Kenya as at December 2020. The study adopted a census methodology while purposeful and convenient sampling was adopted to select respondents amongst the middle level management staff. The study used both secondary and primary data. A self-administered questionnaire was used as the primary data collection instrument. Out of 155 questionnaires that were sent out, 123 were filled and returned. Statistical Package for Social Studies (SPSS) was used for data analysis. The study used regression model to estimate the level of significance which yielded a positive and significant influence of knowledge organization capability on competitiveness of chartered public universities in Kenya. Findings: The findings indicate that organizational initiatives such as effective knowledge collaboration and utilization, deployment of information technology systems that support knowledge organisation and easy access to information and data contribute to a healthy environment conducive for knowledge management. Owing to the foregoing, the study concluded that knowledge organization capability had a significant positive impact on competitiveness of chartered public universities. Unique Contribution to Theory, Practice and Policy: The study recommended that public universities needed to embrace knowledge organization capability in order to obtain sustainable competitive advantage.

The Relationship between Knowledge Sharing Capability and Competitiveness of Chartered Public Universities in Kenya Gachanja, Joseph Nguru Purpose: The purpose of this study was to establish the relationship between knowledge sharing capability and competitiveness of chartered public universities in Kenya. Universities are knowledge intensive environments, and play a central role in the creation and dissemination of knowledge that they generate. Accordingly, it would be expected that such institutions would adopt proactive approaches to the incubation of knowledge management capability and strategies, and that they would have better insight on how to achieve and optimize the value of their knowledge assets. However, research has shown that this is not the case, and that the approaches adopted by universities are passive and inconsistent. In addition, although there is a strong body of research in the area of knowledge management in commercial environments, and growing interest in knowledge management in public sector organizations, there has been little research on knowledge management capability in universities. Methodology: The study adopted a descriptive design. The population of the research consisted of 31 chartered public universities authorized to operate in Kenya as at December 2020. The study adopted a census methodology while purposeful and convenient sampling was adopted to select respondents amongst the middle level management staff. The study used both secondary and primary data. A self-administered questionnaire was used as the primary data collection instrument. Out of 155 questionnaires that were sent out, 123 were filled and returned. Statistical Package for Social Studies (SPSS) was used for data analysis. The study used regression model to estimate the level of significance which yielded a positive and significant influence of knowledge sharing capability on competitiveness of chartered public universities in Kenya. Findings: The findings pointed out that knowledge sharing capability significantly influenced competitiveness of chartered public universities in Kenya. The public universities should therefore entrench knowledge management practices in their day to day operations in order to remain competitive. Unique Contribution to Theory, Practice and Policy: The study recommended that public universities should embrace knowledge sharing practices in their operations as it enhances competitiveness. One of very important factor in knowledge sharing is that university stakeholders should be accorded with formal, informal and virtual space to interact with each other for knowledge exchange.

Impact of Different Vegetation as Riparian Zones in Controlling Nutrients and Sediment Flow Into Water Bodies Assessment of the Kigira, Francis Karanja In this case study nutrients and sediment were considered to be an important water quality concern in Nyangores Catchment in the larger Upper Mara Catchment shown in figure 1 due to high eutrophication of the river as is evident at some sections of the river. Nitrogen and Phosphorous originates from inorganic and organic fertilizer that affect the river water quality due to intensive agricultural farming and livestock grazing. Increased fertilizer application has enlarged N and P nutrient burden into the river through runoff leading to pollution and consequently eutrophication.Three plots of different vegetations were set up to represent different scenarios of riparian vegetation. Plots representing natural forest, grassland and bare land a distance of twenty meters apart to avoid disparity , were set up to determine their effectiveness in controlling the nutrients. The plots each measured 2m by 10m were set up for Natural forest, bare ground and grassland field. Runoff samples were collected from the plots on rainy days, and taken to the laboratory for Ph, Ec, NO3 and PO4 analysis. From the samples analysis the results showed the Ph for the natural forest, bareland and grassland were 7.0, 6.8, and 6.5 respectively, for the nitrates were natural forest 0.20 mg/l, bareland 0.5 mg/l, grassland 0.3 mg/l for phosphates forest it was 0.01gm/l for bareland it wasـ 0.57 mg/l and for grassland 0.55 mg/l. For the Electrical conductivity, forest gave 0.4 mhos, bareland 0.5 mhos and 0.2 mhos for grassland. There is a clear indication that Natural forest on top of controlling the Ph and Ec better than grassland, it has a natural sink for nitrates and phosphate. It is therefore recommended that natural forests be reserved and that grass should be used as an alternative for riparian zones. Key words: Riparian, Nutrients, Water quality, Water bodies.

To Assess the Impact of Land Use Change on Nutrients Flow and to Establish the Level of Key Pollutants of Nyangores River Kigira, Francis Karanja This study was carried out with the aim of assessing the effect of Riparian land use/ land cover change on the hydrology and water quality of the upper Mara River catchment specifically Nyangores River. The study incorporated remote sensing and GIS tools to prepare and analyze the data. It involved sampling of sediments deposits and water flows at various points of the river to quantify water quality parameters such as N, P, Ca and Fe etc. These parameters were tested in the laboratory. Land cover change was analyzed from dry season Land Sat MSS, TM and ETM images of 1976, 1980, 1985, 1990, 1995, 2003, 2006, 2010, and 2014 respectively. Digital image analysis for the riparian zone showed that between 1976 and 2003, crop land increased by about 100%, other vegetation and forests reduced by 32% and 34% respectively with the river line decreasing by 50%. Comparatively high percentages of N, P, Ca and Fe i.e. 0.07meq/100g soil, 0.66meq/100g soil, 12meq/100g soil and 17mg/kg respectively were detected from soils collected along the cattle tracks and in the water directly below the animal tracks. Grass strips along the rivers were found to filter sediment and nutrients and soil from the urban set up and tested high for Fe=46 mg/kg, N= 0.03meq/100g soil K=0.21meq/100g soil caused by channelized flow. Soil composition of 89% sand, 3.4% clay and 7.5% silt which is sandy soil forms the downstream banks of river Nyangores and this is the main cause of the river banks erosion and subsequent sedimentation. Channelization should be controlled and a lot more of grass should be planted along the riparian zone also deep rooted trees should be planted at the downstream of river Nyangores to control river bank Erosion.
