The findings revealed that the negative and positive impacts of natural gas consumption on economic growth are asymmetric in the long run whereas in the short run such evidence has not been found. However, in the long run, the positive impact is 0.15% per 1% increase while the negative impact is insignificant. The implication of the results is that an increase in natural gas consumption can stimulate growth in the long run and, energy efficiency/energy saving policies is not a limiting factor to growth, thus, it does not engender a fall in the rate of economic growth. Therefore, the paper recommends that authorities of the Nigeria's economy boost the domestic demand for natural gas and chart out energy efficiency strategies such as using a light-emitting diode (LED) light bulb or a compact florescent light (CFL) bulb that requires less energy than an incandescent light bulb and water booster heaters. This way, sustainable economic growth, curbing the issue of global warming and, minimising costs of energy consumption can be achieved.

It estimates the long run effect of credit supply constraints on labour productivity using the pooled mean group (PMG) estimator. The results revealed that a reduction in both actual and expected risk premiums increased labour productivity in SSA. The findings suggest that in order to relax the credit supply constraints with the intent to improving labour productivity, domestic interest rate should account for changes in foreign interest rate to enhance the needed capital inflows.

Vector auto-regression model, Johansen co-integration test and Granger causality were used in the analysis for the sample period of 1960-2016. The results indicate that all the variables are co-integrated in long-term. Furthermore, the increase in economic growth by 1% decreases inflation by 1.55%. While the growth in money supply by 1% will increase the price level by 1.15%. According to the results of the causality test, there is no causality direction in short-run among the variables except unidirectional causality among economic growth and money supply running from RGDP to RM2 at the to 5% significance level. In addition, the response of inflation on the economic growth is negative all throughout the ten periods. Also, the same applies to money supply and economic growth. Besides, economic growth has an early and positive impact on money supply.

The study utilised systems analysis to execute an assessment of linkages among actors in the sector. Data collected from questionnaire administration showed that there were technologies available for all five stages of yam flour processing. However, only the milling stage was fully mechanised. Systems analysis revealed a weak innovation system characterised by network failure between innovating units and processors on one hand and among innovating units on the other. This led to inappropriate processing technologies and lack of competence in developing efficient technologies. The study recommended with modifications to existing practices the use of innovation brokers and platforms to strengthen linkages among actors towards building innovative capability among innovating units and facilitating the alignment of processing technologies to the needs of processors.
