The economic impact of climate change on Kenyan crop agriculture : a ricardian approach

This paper measures the economic impact of climate on crops in Kenya. The analysis is based on cross-sectional climate, hydrological, soil, and household level data for a sample of 816 households, and uses a seasonal Ricardian model. Estimated marginal impacts of climate variables suggest that global warming is harmful for agricultural productivity and that changes in temperature are much more important than changes in precipitation. This result is confirmed by the predicted impact of various climate change scenarios on agriculture. The results further confirm that the temperature component of global warming is much more important than precipitation. The authors analyze farmers'perceptions of climate variations and their adaptation to these, and also constraints on adaptation mechanisms. The results suggest that farmers in Kenya are aware of short-term climate change, that most of them have noticed an increase in temperatures, and that some have taken adaptive measures.Climate Change,Environmental Economics&Policies,Common Property Resource Development,Global Environment Facility,Crops&Crop Management Systems

Influence of Selected Factors on the Choice of Capital Structure of Small and Medium Enterprises (SMEs) in Kiambu County, Kenya

This study is on the effect of selected factors influencing the capital structure of small and medium size enterprises in Kiambu County, Kenya. SMEs play a pivotal role towards the achievement of the broad goals outlined in vision 2030 and are critical drivers towards making Kenya an industrialized country with high quality of life for its citizens. The study observes that despite their significance, past statistics indicate that 3 out of 5 SMEs fail within the first few months of operation and those that continue 80 per cent fail before the fifth year; it is therefore necessary to eliminate the many constraints facing these small businesses for Kenya to become an industrialized state by the year 2030. The objectives of the study were to determine the effect of firm size, information availability, purpose of finance, cost of finance, and collateral requirement on the capital structure of SMEs in Kiambu County. The study findings will assist Government planners in understanding how to come up with policies that will help the SMEs sector in raising affordable capital as this will have a great impact on the country’s economic growth; financiers will benefit from the findings by developing a better understanding of the factors that influence the capital structure of SMEs. In addition, the findings from the study will contribute to knowledge about financing decisions of SMEs. The study was guided by pecking order theory, credit rationing theory, the agency theory, and the life cycle approach. This study utilized descriptive research design, employing survey methods. The population of interest are the 889 SMEs in Kiambu County registered in the Kiambu Business Directory. The study used proportionate sampling by utilizing a sample of 268 respondents, determined by Fisher’s formula. The data were collected from interview schedules using questionnaires. Descriptive and inferential statistics (Pearson’s correlation and regression). Data were presented in figures and percentages on pie charts and frequency distribution tables for easier interpretation.  The study findings indicated that the size of the business influenced the capital structure of the firms to great extent (33.6%) and to greatest extent (33.6%) respectively compared with those who were not sure at 18.7%. Availability of information influenced choice of capital structure to a great extent (36.2%) and to greatest extent (45.5%) respectively.  The purpose of the finance influenced choice of capital structure to a great and greatest extent according to 39.9% and 47.8% of the respondents. Personal savings were generally recommended for SMEs with 22.0%, 29.1% and 48.9% of the respondents indicating average, high and very high recommendation. Family and friends borrowing got mixed recommendation with 23.5% and 24.3% of the respondents indicating low and high recommendation respectively, compared with 45.1% who gave average recommendation. Finally, the research sought to test the hypotheses in order to fulfill the objectives of the study by using Pearson’s correlation and regression model and applying t-test to test for the significance in the relationship. All of the null hypotheses were rejected on the basis that the significance of the t-statistic was 0.000 which was less than p-value 0.05 set for the study. Therefore, all the selected factors had an impact on the choice of capital structure for SMEs in Kiambu County. Keywords: Capital Structure, Small and Medium Enterprise

Effect of Credit Risk Management Practices on Lending Portfolio among Savings and Credit Cooperatives in Kenya

Sound lending procedures in financial institutions involve identifying high-risk loan applicants, modifying lending conditions such as security requirements and monitoring repayments. Credit risk management is an emerging activity that lies within Sacco’s. Many researches have attempted to answer the benefits of the credit risk management. However, it has remained unclear for the Sacco’s management on the effects of credit risk management practices on lending portfolio. The purpose of this study was to examine the effects of credit risk management practices on lending portfolio among Sacco’s in Nakuru County, Kenya. Data on risk identification, risk analysis, risk monitoring, risk evaluation and risk mitigation obtained from 59 Sacco’s sampled from among Saccos in Nakuru County were analyzed using regression models to identify its effect on lending portfolio. Results indicate a significant effect of all the risk management practices on lending portfolio except risk evaluation which did not register a significant effect on the lending portfolio of the Sacco’s. The findings further show that majority of the Sacco’s have largely adopted risk management practices as a means of managing their portfolio.

High coverage of long-term follow-up of patients with spinal tuberculosis

A total of303 patients treated for spinal tuberculosis were systematically followed up for a period of 8 years. There were a total of 2243 attendances due during the period; the patients attended on the due date on 70.9% of these occasions, and after defaulter actions on 27.7% occasions. The coverage of 98.6% for an 5-year follow-up was obtained even though on 50% of these occasions, patients attended from a suburban area or from outside the city. An average of 13 visits per default were made and 0.9 letters were posted to retrieve those who did not attend on the due date. Thus, the high coverage obtained can be attributed to effective motivation of the patients by theclinic staff and intensive defaulter actions

Modern contraceptive use among postpartum women living with HIV attending mother baby care points in Kabarole District, Uganda

Background: Preventing unintended pregnancies among women living with HIV is important for improving maternal and child health outcomes. Despite multiple contacts between postpartum women and healthcare providers at health facilities, modern contraceptive use during postpartum period remains low even among women with intentions to limit or delay childbearing. We estimated postpartum modern contraceptive use, unmet need and factors associated with modern contraceptive use among HIV positive women attending mother-baby HIV care points. Methods: We conducted a cross-sectional study, between April and May 2016, among HIV positive women attending postpartum care at six health facilities in Kabarole district, Uganda. Health facilities were stratified by level prior to selecting participants using systematic sampling. We administered structured questionnaires to women who had delivered within the last two to 18 months. Women who reported current use of a modern method were categorized as modern contraceptive users. Women not using but wanted to stop childbearing or space childbirth by at least 2 years were considered to have unmet need for modern contraception. We estimated a modified Poisson regression model to examine variations in the use of modern methods by various characteristics of participants. Results: We interviewed 369 women. Forty percent of them were using a modern method, with injectables being the most widely used. A third (33%) of the women had unmet need for modern methods, with unmet need for spacing (24%) being higher than for limiting births (9%). Modern contraceptive use was significantly higher among women who had delivered seven or more months earlier (Adj.PR = 2.02; CI: 1.49, 2.74); women who were counseled on family planning during antenatal care (Adj.PR = 1.53; CI: 1.07, 2.18); those who obtained methods through the care points (Adj.PR =2.27; CI: 1.32, 3.90); and those who jointly made decisions regarding childbearing with their partners (Adj.PR = 1.49; CI: 1.02, 2.17). Conclusion: Use of modern contraceptives was low while unmet need was high among postpartum women living with HIV. The findings suggest that there are gaps which indicate the need to strengthen contraceptive service delivery at these care-points. Providing family planning counseling early would improve uptake of contraception upon resumption of menses and sexual activity.publishedVersio

Precision Doppler Shift Measurements with a Frequency Comb Calibrated Laser Heterodyne Radiometer

We report precision atmospheric spectroscopy of $CO_2$ using a laser heterodyne radiometer (LHR) calibrated with an optical frequency comb. Using the comb-calibrated LHR, we record spectra of atmospheric $CO_2$ near 1572.33 nm with a spectral resolution of 200 MHz using sunlight as a light source. The measured $CO_2$ spectra exhibit frequency shifts by approximately 11 MHz over the course of the five-hour measurement, and we show that these shifts are caused by Doppler effects due to wind along the spectrometer line of sight. The measured frequency shifts are in excellent agreement with an atmospheric model, and we show that our measurements track the wind-induced Doppler shifts with a relative frequency precision of 100 kHz (15 cm/s), equivalent to a fractional precision of a few parts in $10^{10}$. These results demonstrate that frequency-comb-calibrated LHR enables precision velocimetry that can be of use in applications ranging from climate science to astronomy.Comment: 4 pages, 3 figure

Influence of Special Needs Education Policy on Access to Secondary School Education By Learners With Hearing Impairments In Nandi County, Kenya

This study sought to examine influence of Special Needs Education Policy on access to secondary school education by learners with hearing impairments in Nandi County, Kenya. The study was informed by the Multiple Intelligences theory and the Dewey theory of Progressivism. The findings showed that majority of the respondents were aware of the Special Needs Education Policy Framework of 2009 and believed that the policy was being implemented. Majority of the respondents felt that the implementation of the policy had positively affected learners’ enrolment in schools but recognized that there were still several challenges that were acting as barriers to school access by learners with hearing impairments in Nandi County. Further, the respondents observed that the implementation of the Special Needs Education Policy had led to a slight improvement on transition of learners with hearing impairments from primary to secondary schools in Nandi County. The influence of the Special Needs Education Policy on retention of learners with hearing impairments was deemed to be marginally small in schools in Nandi County. The results also showed that there were cases of learners dropping out of school because of a number of reasons including financial problems, lack of motivation to be in school and cultural factors, among others. In order to improve access to school education by learners with hearing impairments, respondents gave their opinions on how the challenges could be handled including the need to train more teachers to teach learners with hearing impairments, provision of adequate learning materials and the need to fund the special units/schools for the hearing impaired in the county, among others. The study recommends that the Government should set clear guidelines on how the Special Needs Education Policy can be implemented and coordinated. The study also recommends increase of necessary support for the secondary and primary school/units for the hearing impaired in the county so as to improve access to school education by children with hearing impairments.
