Plant Nutrition and Sustainable Crop Production in Nigeria

The aim of this study is to examine the determining factors of plant nutrition and sustainable crop production in Nigeria. The study applied an in-depth review of literature and observed that different biotic and abiotic factors interact together to determine the outcome of plant nutrition and sustainable crop production in Nigeria. These factors include; types of fertilizers applied, atmospheric emissions, level of technological development, infrastructural facilities, climatic conditions, irrigation method, and level of skilled labour force. The study recommended that there should be increased and equal access to credit facilities, social protection incentives, and more innovation and technological involvement in the agricultural sector in order to increase productivity and efficiency

Electricity Consumption, Government Expenditure and Sustainable Development in Nigeria: A Co-integration Approach

The government incurs both capital and recurrent expenditures so as to bring about the development of the Nigerian economy. Coupled with this is the fact that electricity power plays an important role in ensuring that aggregate output increases and the welfare of the people is affected positively. This study sets out to examine the long run relationship between electricity consumption, government expenditure and sustainable development in Nigeria employing the Johansen co-integration, Vector Error Correction Mechanism (VECM) and Granger causality estimation techniques. Secondary data were obtained from Central Bank of Nigeria Statistical Bulletin, United Nations Conference on Trade and Development (UNCTAD) and World Development Indicators (WDI) from 1980 to 2017. The results obtained from the study showed that government recurrent expenditure, gross fixed capital formation have a positive and significant relationship with GDP per capita in the long run. However, electricity consumption, government capital expenditure and total labour force had a negative but significant effect on GDP per capita in the long run. Hence, this study recommended that the government and relevant agencies should ensure that projects undertaken are profitable and people oriented. Also, strategies to improve electricity supply, government expenditure on capital and labour productivity should be encouraged.

Do Information and Communications Technology (ICT) and financial development contribute to economic diversification? Evidence from sub-Saharan Africa

Abstract This study based on a panel of 37 sub-Saharan Africa countries over the period of 2000–2019 explores the effect of a number of Information and Communications Technology variables namely fixed broad band, fixed line telephone, Information and Communications Technology good imports, internet, mobile, and secure internet servers, and financial development measured by private sector domestic credit to GDP on economic diversification as measured by a computed Herfindahl–Hirschman Index of economic diversification. Model estimation was performed using pooled ordinary least squares regression, panel data fixed effects regression, and generalized method of moments regression. The results from findings indicated that the Information and Communications Technology variables: fixed-line telephone, and ICT imports significantly reduced economic diversification, while internet and mobile were, respectively, insignificant for boosting economic diversification, and fixed broadband and secure internet servers were insignificant in adversely affecting economic diversification. As regards financial development, it was insignificant in boosting economic diversification of sub-Saharan Africa countries. The study recommended amongst others that individuals in sub-Saharan Africa countries should have improved access to Information and Communications Technology infrastructure and governments should ensure adequate provision of quality Information and Communications Technology infrastructure

Secondary data were obtained from Central Bank of Nigeria Statistical Bulletin, United Nations Conference on Trade and Development and World Development Indicators from 1980 to 2017. The results obtained from the study showed that government recurrent expenditure, gross fixed capital formation have a positive and significant relationship with gross domestic product per capita (GDPC) in the long run. However, electricity consumption, government capital expenditure and total labour force had a negative but significant effect on GDPC in the long run. Hence, this study recommended that the government and relevant agencies should ensure that projects undertaken are profitable and people oriented. Also, strategies to improve electricity supply, government expenditure on capital and labour productivity should be encouraged.
