Effect of Load Shedding on Small Scale Entrepreneurs: A Case of Kitwe District of Zambia

Electricity is one of the key factors that are critical for accelerating the growth of the economy of the country. Without electricity, a number of sectors are affected. From 2014, Zambia has been facing serious load shedding which has an effect on the lives of people from academia to industry. The study was designed to determine the effect of load shedding on small scale entrepreneurs in Zambia. The approach for the study was mixed research. The sample for the study consisted of 200 people working in bars, salons, barbershops and in cafes. Simple random sampling was used to come up with 200 participants. Data for the study were collected through questionnaire and face to face interviews. Data for the study were analyzed using Analysis of Covariance. The null hypothesis was tested at 5% significance level. The findings of the study revealed that load shedding has negative effect on small scale entrepreneurs in Zambia

An Investigation on the Relationship between the Level of Education and Monthly Income: A Case of Kitwe District of Zambia

Reducing high level of poverty and hunger, and achieving universal primary education in many developing countries are some of the Millennium Development Goals. The current study was designed to investigate the relationship between the level of education and monthly income in the city of Kitwe in the Copperbelt Province of Zambia. The design of the study was descriptive and quantitative.  Simple random sampling was used in this study to come up with the sample of  informal and formal employees who participated in the study. Questionnaire was used to collect data regarding the relationship between the level of education and monthly income. Data was analysed using Chi-square test of independence.  (The null hypothesis) was tested at  level of significance. Results of the study shows that there is a significant relationship between the level of education and monthly income in Zambia. The study recommended that a number of studies should be conducted in Zambia regarding the relationship between the level of education and monthly income to further confirm the results

Data to understand the biotransfer of heavy metals along the soil-plant-edible insect-human food chain in Africa

Data on the biotransfer of heavy metals along the soil-plant-edible insect-human food chain collected along a 60km pollution gradient is presented here. These datasets consists of concentrations of eight heavy metals (Arsenic, Cadmium, Copper, Chromium, Iron, Nickel, Lead and Zinc) in the soils, in five host plants species, and in seven edible insect species determined using Atomic Absorption Spectrophotometry (AAS). Datasets for the daily intake of metals and target hazard quotients for each edible insect species are also given. These data demonstrate the potential biotransfer of heavy metals along the soil-plant-edible insect-human food chain, and that edible insects harvested in heavy metal-polluted environments could pose serious health risks. These datasets provide further understanding of the relationships among metal concentrations in the soils, host plants and edible insects, particularly in the mining regions.
