Technology and innovations have fueled the evolution of the fourth industrial revolution (Industry 4.0). Industry 4.0 spurs growth and development through its efficiency capacity, as documented in the literature. The growth of the construction industry is a subset of the universal set of the value of gross domestic product, and thus, industry 4.0 has a spillover effect on the engineering and construction industry. The aim of this paper is to map the state of Industry 4.0 in the construction industry from the point of view of manarial activities, such as investment management, project preparation, and an overall approach to the management of related activities. This study employed scoping review techniques to dissect the status quo for Industry 4.0 and the construction industry. The empirical results from the systematic and scoping review methods for the ten sampled publications revealed that information and communication technology (ICT)—Industry 4.0—has a significant positive impact on the growth of the construction industry. Therefore, construction practitioners should partner more with researchers in the ICT industry to enhance the automation of work processes and managerial activities in the engineering and construction industry.

Africa is an emerging, frontier economy that is gradually becoming a gold miner of the fourth industrial revolution (industry 4.0) to achieve speedy economic growth and development. Through the transmission channel of technological drive that relies on the penetration of modern communication means (information and communication technology [I.C.T.]). It is on this basis that this study examines the performance of I.C.T., economic growth and development in Africa. In capturing I.C.T. performance; penetration of I.C.T. indicators – mobile telephone, fixed-line telephone and Internet access subscriptions are used as measurements and reduced to a single index through principal components analysis (P.C.A.). Economic growth and development is measured with the real gross domestic product and the human development index (H.D.I.), respectively. The data for this study were sourced from the international telecommunication union (I.T.U.) and world development indicators from the World Bank databases. The results show that mobile telecommunication is growing faster than other telecommunication indicators and I.C.T. penetration has positive impacts on economic growth and development in Africa. The study, therefore, recommends that simultaneous investments are required in the fixed-line and Internet access telecommunications in Africa in order to fully tap into the optimal impetus of I.C.T. penetration for economic growth and development in Africa.

This study investigates the effect of telecommunication operations on economic growth and development in selected African countries. The analysis considers a panel of 46 African countries from 2000 to 2015. To measure economic growth, real gross domestic product serves as the proxy, while economic development is measured by the Human Development Index, and telecommunication operations by a composite index of telecommunication computed from mobile line, fixed/CDM line and Internet access penetration via principal component analysis. The physical capital stock is measured by gross fixed capital formation, level of employment by the employment to population ratio, human capital development by enrolment in secondary education for both sexes and technology transfer by net inflows of foreign direct investment in Africa. The empirical results suggest that telecommunication operations promote economic growth and development in Africa. These results imply that for every positive expansion in telecommunication operations and physical capital stock, aggregate output and standard of living will adjust positively in Africa. Thus, an appropriate policy to improve overall investment in Africa and most especially in the telecommunication sector since the spillover effect cut across other sectors and the general economic performance.

The positive spillover impacts of the efficiency of information and communication technology (ICT) and land accessibility as factor inputs to agricultural productivity are well documented in the literature. Furthermore, input-output efficiency as a measurement of factors contributing towards gross production is no exception in this regard. Few studies on agricultural production and ICT at the household level in South Africa show divergent empirical results. This study investigates the effect of information and communication technology (ICT) and land for farming in the context of household food production in South Africa. Household engagement in agricultural activities is proxy for agricultural production, farm land size is a proxy for land accessibility, telephone and internet use are proxies for ICT in this study. Household data of twenty-one thousand, six hundred and one (21,601) households on agricultural activities and ICTs were generated from the existing survey data of General household survey, 2015 by Statistics South Africa. Majority of the households are not engaging in agricultural activities due to no access to land for farming, but more than 80 percent of the households have access to at least one form of ICTs penetration i.e. mobile telephony. The logit regression shows that internet connection in the household have positive and significant impact on household agricultural production but land accessibility is indirectly related and significant to household food production in South Africa. Therefore land accessibility may be a barrier to agricultural activity involvement in South Africa. The study shows that the positive spillover impacts of ICT may not be possible due to lack of access to land for agriculture. Land for farming, CDMA telephony and internet are highly required for agricultural activities in order to promote food production, reduce cost of telecommunications, promoting agricultural research and development via internet accessibility.
