This study aimed at the assessment of the perspective of the people of Kano-south senatorial district, Nigeria on solar powered borehole projects. This research sought to establish the performance of solar-powered boreholes in terms of presence, their importance, their performance, and maintenance culture as well as provide solutions to possible problems that the senatorial district may be encountering in the usage of these amenities to ensure good sustainability. The survey research method was adopted for this study, and data were collected from 400 people who represented the sample size. The analysis of the data collected showed that 88.6% of the respondents affirmed the presence of solar-powered boreholes in the study area, which is in line with the hypothesis analysis. Similarly, the result showed that although the solar-powered borehole projects have positive impacts on the standard of living of the populace, most of these amenities are not functional due to the low regularity of borehole maintenance. Based on the views of the end-users, it was recommended that the involvement of community leaders and other end-users, proper training of the end-users, provision of channels of reporting damages, the building of more solar-powered boreholes and adequate provision for maintenance are some of the ways to ensure better sustainability of solar-powered boreholes projects in the senatorial district.

This paper estimates a nonlinear augmented New Keynesian Philips Curve for Nigeria using the Smooth Transition Regression model for the period 1995Q1 to 2018Q2. The empirical evidence reveals the existence of two inflation regimes during the period under review. Food inflation, energy inflation, firms’ marginal cost, and imported inflation account for most of the changes in the prices of composite consumers’ basket in low exchange rate depreciation regime. However, the exchange rate solely explains price changes in the composite consumers’ basket when inflation switches to high regime. Similarly, the results show that regime change in inflation is largely caused by exchange rate (transition variable) depreciation or devaluation of the naira. Furthermore, the paper finds that the threshold in exchange rate devaluation (depreciation) that triggers a regime switch from low to high inflation regime is about N75 relative to a dollar. The speed of regime switch was found to be significantly high at about 70% per quarter. The paper argues that achieving exchange rate stability is a necessary condition for disinflation during this regime. Therefore, this paper recommends that monetary policy response to low inflation regime must target the various components of the consumption basket while effort to curtail persistent high inflation must include a stable exchange rate of the naira.
