The construction industry is plagued with significant construction and demolition waste (C&DW) generated during various phases of construction projects. This waste has created a universal, pervasive, and enduring problem globally. To propose practical solutions to resolve this consequential issue, this research adopted a quantitative approach in two stages. The first stage involved an online survey, administrated to 360 methodically selected construction organisations working in Egypt, to evaluate the impact of six main factors on C&DW reduction (C&DWR). The six main factors are as follows: (1) materials procurement measures (MPMR); (2) materials procurement models (MPMO); (3) green building practices (GBPR); (4) legislation (LG); (5) culture and behaviour (CB); and (6) awareness (AW). The second stage comprised multivariate statistical analysis via the structural equation modelling (SEM) approach to develop an integrated framework for C&DWR, to support Egypt’s vision 2030. The results revealed that these six factors positively affect C&DWR in Egypt. Additionally, the study found that GBPR has the highest importance value of 0.293 and the highest performance rate of 92.169. However, CB has the second highest importance value of 0.238 whilst it has the lowest performance of 72.08 among the six factors. This paper proposes practical recommendations for the government and the construction sector to reduce the C&DW in support of Egypt's Vision 2030.

There have been limited studies analyzing the causes of construction workers’ unsafe behaviour from the social psychology perspective. Based on a Grounded Theory approach, this study first identified and defined seven coded categories related to workers’ dangerous behaviour on construction sites. The original qualitative data were obtained from individual site interviews conducted with 35 construction professionals. These main categories were found connected to workers’ status of safety awareness and sense of danger, which affected the type of unsafe behaviours, i.e., proactive, passive, or reactive behaviour. By further integrating social cognitive psychology theories into workers’ behavioural decision-making process, the formation mechanism framework and diagram were developed to describe construction workers’ unsafe behaviours based on the dynamic process of balancing the individual desires and perceived safety risks. This study advances the body of knowledge in construction safety behavioural management by performing in-depth theoretical analysis regarding workers’ internal desires, activated by external scenarios and intervened by a personal safety cognition system, which could result in different motivations and various behavioural outcomes. It is argued that safety cognition serves as a mediated moderation system affecting behavioural performance. Practical suggestions on developing a proper safety management system incorporating safety education in guiding construction workers’ site behaviours are presented.

Construction and demolition waste (CDW) is a critical challenge facing the construction industry. It leads to deterioration of the triple bottom line of sustainability. Unfortunately, the CDW management research in Egypt lacks studies investigating (1) the variations in CDW generation (CDWG) among different types of construction projects, and (2) the factors affecting CDW reduction (CDWR). Based on a benchmarking approach, this research (1) quantifies CDW in terms of generation rates and costs among different construction project types in Egypt, and (2) investigates the relationship between CDWG and different adopted CDWR factors. Using structured interviews, a comparative case study was conducted to investigate industrial, residential, commercial, and infrastructure projects. Analysis of results demonstrated that CDWG rates and costs differ from one project type to another due to the project's nature, size, and complexity on the one hand, and the applied CDWR factors such as waste-efficient practices, awareness, culture & behaviour, and legislation on the other hand. On average among the four project types, it was found that “timber”, “sand”, and “bricks/blocks” are the most wasteful materials. It was also found that “practices” and “legislation” are the least applied CDWR factors on average among the four project types, which need to be better applied for better CDWR results.

Construction projects are associated with construction and demolition waste (CDW) generated at different stages. In Egypt's case, the CDW problem has become a significant challenge, and the need to find sustainable solutions is overwhelming. Based on recent investigations in the literature, it was found that six main factors are affecting CDW reduction (CDWR) as follows: (1) waste-efficient materials procurement measures; (2) waste-efficient materials procurement models; (3) green materials procurement approach; (4) legislation; (5) culture & behaviour; and (6) awareness. In this study, a representative sample of Egyptian construction firms was screened to (1) investigate the applicability and effectiveness of CDWR factors in the Egyptian construction sector; and (2) examine the relationship between these factors and CDWR. The results revealed that (1) among different factors, “correct materials purchase” is the most applied item while “reducing overall material use by using prefabricated elements and highly durable materials” is the most effective item; and (2) there are statistically significant positive relationships between CDWR and different factors except “legislation”. The results demonstrate the necessity of developing a conceptual framework, as a next research initiative, consisting of these different factors for CDWR in Egypt.

PurposeSustainable urbanism is the study of both cities and the practices to build them, which focusses on promoting their long-term viability by reducing consumption, waste and harmful impacts on people and place while enhancing the overall well-being of both people and place. This paper analyses the implications of adopting sustainable urbanism principles and developing resilient places with Abuja as the area of focus to tackle the highlighted issues.Design/methodology/approachThe paper is based on qualitative research which is centred on an extensive literature review and archival retrieval of historical documents. This includes the emergence of urbanism, sustainable urbanism definition and current issues surrounding its adaptation. The paper also focusses on a case study area in the capital city of Abuja, Nigeria which is currently undergoing massive urban development. Interviews are conducted with academics (13), practitioners (12) and government officials (10) making a total of 35 participants.FindingsThe main findings will create an understanding of the definition of sustainability and sustainable urbanism with a special focus on Abuja city. It was realised from the interviews that sustainable urbanism in broad terms encompasses economic, social, and environmental sustainability, and that these dimensions vary across different contexts even in the developing world. Also, sustainability can be achieved through deploying the right combination of measures, policies, assessment tools, sustainability assessment, good governance, and training/education and incentives.Originality/valueBy reviewing the selected studies which explore a wide range of disciplines and research areas, and conducting this qualitative research, this paper shares insights into how sustainability and sustainability urbanism can be achieved in the development of urban spaces in Abuja environs.

Despite the tangible contributions of the construction industry to social development and economic growth, it is known for its natural resources overconsumption and solid waste (SW) generation both...

Purpose Against the backdrop of the changing trends in tenure in the UK housing system, young adults are faced with different situations that continue to shape their housing consumption and decisions. The purpose of this paper is to investigate the relationships amongst young adults’ housing tenure, social capital and elements of perceived job security in Britain. Socio-psychological dimension of housing tenure decisions has been receiving attention by housing market analysts and practitioners seeking deeper understandings of the UK housing market dynamics, particularly in the wake of changing tastes and preferences of young people concerning housing decisions across major cities of the world. Design/methodology/approach A quantitative approach has been applied to the harmonised version of the British Household Panel Survey (BHPS) from 2001 to 2015. Findings The authors discovered that British young adults’ homeownership decisions are increasingly influenced by social capital and elements of perceived job insecurity, depending on their tenure of origin. Furthermore, this study will significantly enhance the understanding of tenure shifts amongst young adults in the UK and provide property developers, local authorities and central governments the knowledge and information to guide economic policies, urban renewal towards achieving better social cohesion and sustainable communities. Originality/value Very little has been done to investigate the contributions of social capital formation, for example, neighbourhood or social integration and social relations and elements of perceived job security on housing tenure transitions among British young adults. This study will further provide property developers, local authorities and central governments the knowledge and information to guide economic policies, urban renewal towards achieving better social cohesion and sustainable communities.

Purpose The Purpose of this paper is to identify statistical relationships between visual environment and occupant productivity. Visual environment is one of the most important indoor environmental quality (IEQ) parameters, and it directly impacts occupant productivity in offices. The literature outlines the significance of the impact. Still, there is a lack of investigation, statistical analysis and inter-relationships between the independent variables (IEQ factors), especially in the hot and arid climate. Design/methodology/approach This study presents a research study investigating the effects and shows statistical relationships between IEQ on occupant comfort and productivity. The study was conducted in the Middle East, and data was collected for 12 months. It used the response surface analysis to perform analysis. Findings This study outlined seven unique relationships highlighting the recommended range, inter-dependencies. Results include that illumination has maximum effect on visual comfort and temperature, daylight having direct influence and relative humidity, wall type next to the seat and kind of workspace also impact visual comfort and productivity. These findings would help to improve occupant comfort and productivity in office buildings. It is recommended to include results and recommendations on design guidelines for office buildings. Originality/value This study presents the unique effects of non-visual IEQ parameters on visual comfort and productivity. This investigation also provides a unique method to develop the statistical relationship between various indoor environmental factors and productivity in different contexts and buildings.

Purpose A major challenge for foreign lenders in financing public private partnerships (PPP) infrastructure projects in an emerging market (EM) is the bankability of country-related risks. Despite existing studies on country risks in international project financing, perspectives of foreign lenders on bankability of country-specific risks in an EM is yet to be explored. Hence, using a mixed methodology approach, three private finance initiatives/PPP projects in Sub Saharan Africa (Nigeria) were used to investigate political risk, sponsor, concession and legal risks in PPP loan applications. The paper aims to discuss these issues. Design/methodology/approach The study adopted mixed methodological approach comprising focus group discussions and analysis of loan documents obtained from foreign project lenders, in addition to the questionnaire survey distributed to local and international project financiers with experiences in PPPs within Nigeria. Findings Results identified seven topmost bankability criteria for evaluating country-related risks (political risk, sponsor, concession and legal risks) in EM PPPs. In addition, a “Risk and Bankability Framework Model” was developed from the study presenting critical parameters for gaining foreign funding approval for EM’s PPP loan applications. Research limitations/implications Since the study only explored bankability of PPPs in Sub Saharan Africa with the exclusion of other geographical regions, the proposed framework model should be taken in context of EMs as a mind-map for foreign lenders and local private investors seeking to finance PPPs in an EM. Practical implications Results from the study represent critical parameters for winning foreign loan approval for PPP infrastructure projects within an EM context. Originality/value Study proposed “Risk and Bankability Framework Model” relevant for evaluating PPP loan applications at the pre-approval stage for EM PPPs.

© 2020 Elsevier Ltd Thermal environment is one of the main factors that influence occupants' comfort and their productivity in office buildings. There is ample research that outlines this relationship between thermal comfort and occupant productivity. However, there is a lack of literature that presents mathematical relationship between them. This paper presents a research experimental study that investigates effects of indoor environmental quality factors on thermal comfort and occupant productivity. This study was conducted by collecting indoor environmental quality parameters using sensors and online survey for twelve months. Data analysis was done using Response Surface Analysis to outline any mathematical relationship between indoor environmental quality and occupant productivity. The outlined relationships confirmed dependencies of occupant thermal comfort and productivity on various indoor environmental factors. These dependencies include the effect of CO2 concentration, VOC concentration. These relationships were analysed to rank nine indoor environmental parameters as per the degree of effect on occupant thermal comfort and productivity. These findings would help design professionals to design better office design that would improve occupants’ comfort and their productivity. Study results have different implications for professionals working in design, construction and operation of office buildings. It is recommended that design guidelines for office buildings should consider occupant productivity and incorporate recommended range for indoor environmental quality parameters in respective categories and criteria.

Sub-Saharan Africa’s urban culture makes open marketplaces an essential part of life in their cities. What goes on in these markets undoubtedly opens them up to threats of adversity, tragedy, and other significant sources of stress. How can these open marketplaces be regenerated into resiliently sustainable places? From a case study of the regeneration redevelopment of the largest open-air market in West Africa i.e. Kumasi Central Market, the need for stakeholder participation in the entire regeneration process is emphasised. The determination of the most important stakeholders during the regeneration of the market is followed by a comparison of the regeneration process regeneration with the literature on urban regeneration, sustainable development, participation, and project management. Lessons learned, and the concerns raised by major stakeholders in the process creates certain project management approaches essential for achieving resilient urban regeneration. Identification of all important stakeholders by the consideration of their attributes of power, legitimacy and urgency and distrustfully engaging all stakeholders is vital to the success of any urban regeneration project.

Housing has been experiencing significant rework within the supply chain. Rework has afflicted both cost and schedule of projects due to the complex environment, intricate activities and highly fragmented nature of housing supply chain. Housing supply chain generate immense data and share information with different parties, which contribute to multitude of countless challenges. As a result of rework, productivity and workflow of information in construction supply chain has been affected with a catalogue of problems for the past few decades. Automation in construction supply chain with novel technological and analytical strategies has aspired industry to improve the productivity and change the trajectory of traditional, manual and analogue way of processing. The aim of this study is to explore possible opportunities of employing new technologies and challenges involved in utilising automated technologies for minimising rework in housing supply chain. The research methodology is based on a review of literature to investigate automated technologies to eliminate rework in housing supply chain. A conceptual framework is proposed to determine the suitability of various technologies to fully automate housing supply chain and facilitate the reduction of rework in construction housing supply chain.

Digital technologies such as Virtual Reality (VR) are gaining momentum in its use to implement and deepen construction health and safety education. In this study, researchers first developed a VR-driven immersive system incorporating real construction site hazard scenarios. Immersive experiments were then conducted by recruiting 40 individuals in construction-related disciplines. Experimental data were collected to evaluate the effects of tasking mode and time pressure on individuals’ cognitive load in performing virtual site tasks. The self-evaluation method and task performance-based data were adopted as the complementary ways to measure individuals’ cognitive load in completing given tasks. Compared to the single tasking mode of solely focusing on site hazard recognition, analysis, and reaction, the added secondary task was found significantly increasing individuals’ cognitive load and lowering task performance. Time pressure could be a double-edged effect depending on the task feature. Recommendations were provided for real site safety management in balancing employees’ wellbeing and site productivity. The current study extends prior research on enhancing construction health and safety where the main focus has been on hazard detection but now incorporates also hazard analysis and reaction. It also leads to more future research such as measuring individuals’ cognitive load in a real site environment.

East African region is susceptible to drought due to high variation in monthly precipitation. Studying drought at regional scale is vital since droughts are considered a ‘creeping’ disaster by nature with devasting and extended impact often requiring long periods to reverse the recorded damages. This study assessed drought exceedance and return years over East Africa from 1920 to 2016 using Climate Research Unit (CRU) precipitation data records. Meteorological drought, where precipitation is the central quantity of interest, was adopted in the work. Standardize Precipitation Index (SPI) was used to study long term meteorological droughts and also to assess drought magnitude, frequency, exceedance probability and return years using Joint Probability Density Function (JPDF). Also, Mann-Kendall trend analysis was applied to precipitation and SPI to investigate the trend changes. Results showed that years with high drought magnitude ranged from 1920−22, 1926−29, 1942−46 and 1947−51 with values corresponding to 2.2, 3.2, 3.4 and 2.6, respectively while years with low drought magnitude ranged from 1930−31, 1988−89 and 2001−02 with values as 0.2, 0.12 and 0.15, respectively. The longest droughts occurred from 1926−29, 1937−41, 1942−46, 1947−51, 1952−56, and 1958−61 with values in years as 3, 4, 4, 4, 4, and 3 years, respectively, while the shortest droughts occurred in time period of 1 year and ranged from 1930−31, 1964−65, 1979−80, 1981−82, 1983−84, 1988−89, 1991−92, 1993−94, 1996−97 and 2001−02. Also, it was demonstrated that probability of drought occurrence is high when severity is low and such droughts occur at short time intervals and not all severest drought took longer periods. The SPI trends indicate high positive (negative) pixels above (below) the zero-trend mark, indicating that drought prevails in both low and high elevation areas up to 2000 m. There was no direct link between ENSO and drought but arguably the association of drought in most El Nino and La Nina years suggests that the impact of ENSO cannot be ruled out since peak ENSO events occur during October to March periods which coincides with the short (SON) and long (MAM) rainy seasons of East Africa. The study is particularly relevant in being able to depict continuous and synoptic drought condition all over East Africa, providing vital information to farmers and policy makers, using very cost-effective method.

Sustainable urban planning is essential in mediating the natural and built environments globally, yet, there is little progress as regards its attainment in developing countries. Rapid and unplanned urbanization continue to threaten the sustainability of many cities in Africa. By selecting Morogoro Municipal Council (MMC) in Tanzania as an example, this study applied well-known remote sensing techniques to understand the dynamics of urban growth and the implications for sustainable urban planning. The study analyzes spatio-temporal characteristics for eighteen years (2000&ndash, 2018) based on urban land density using gradient and grid-based analysis to further examine land use and urban land density nexus. The results indicate declining urban land densities with distance to the city center, indicating a less compact and fragmented development at the urban fringes, and northward development with limited development to the south of MCC. The knowledge and understanding of the patterns of spatio-temporal conditions, land use planning, and management interventions in MMC are necessary for addressing the inadequacies associated with rapid urbanization within the study area. On this basis, we propose a shift from the modernist to the communicative planning strategy that strongly integrates the urban social, economic, and environmental imperatives, while being adaptable to evolving realities. This plan should also aim to curtail urban sprawl and create a viable city system and economically prosperous city structure for MMC.

The need to decompose CO2 emission intensity is predicated upon the need for effective climate change mitigation and adaptation policies. Such analysis enables key variables that instigate CO2 emission intensity to be identified while at the same time providing opportunities to verify the mitigation and adaptation capacities of countries. However, most CO2 decomposition analysis has been conducted for the developed economies and little attention has been paid to sub-Saharan Africa. The need for such an analysis for SSA is overwhelming for several reasons. Firstly, the region is amongst the most vulnerable to climate change. Secondly, there are disparities in the amount and composition of energy consumption and the levels of economic growth and development in the region. Thus, a decomposition analysis of CO2 emission intensity for SSA affords the opportunity to identify key influencing variables and to see how they compare among countries in the region. Also, attempts have been made to distinguish between oil and non-oil-producing SSA countries. To this effect a comparative static analysis of CO2 emission intensity for oil-producing and non oil-producing SSA countries for the periods 1971–1998 has been undertaken, using the refined Laspeyres decomposition model. Our analysis confirms the findings for other regions that CO2 emission intensity is attributable to energy consumption intensity, CO2 emission coefficient of energy types and economic structure. Particularly, CO2 emission coefficient of energy use was found to exercise the most influence on CO2 emission intensity for both oil and non-oil-producing sub-Saharan African countries in the first sub-interval period of our investigation from 1971–1981. In the second subinterval of 1981–1991, energy intensity and structural effect were the two major influencing factors on emission intensity for the two groups of countries. However, energy intensity effect had the most pronounced impact on CO2 emission intensity in non-oil-producing sub-Saharan African countries, while the structural effect explained most of the increase in CO2 emission intensity among the oil-producing countries. Finally, for the period 1991–1998, structural effect accounted for much of the decrease in intensity among non-oil-producers, while CO2 emission coefficient of energy use was the major force driving the decrease among oil-producing countries. The dynamic changes in the CO2 emission intensity and energy intensity effects for the two groups of countries suggest that fuel switching had been predominantly towards more carbon-intensive production in oil-producing countries and less carbon-intensive production in non-oil-producing SSA countries. In addition to the decomposition analysis, the article discusses policy implications of the results. We hope that the information and analyses provided here would help inform national energy and climate policy makers in SSA of the relative weaknesses and possible areas of strategic emphasis in their planning processes for mitigating the effects of climate change.

Nigeria's electric power sector requires substantial reform if the country's economic development and poverty alleviation program is to be realised. This understanding is behind the reform programme recently initiated by the Nigerian government with the goal of privatising the national electric power monopoly, NEPA. Currently, the country faces serious energy crisis due to declining electricity generation from domestic power plants which are basically dilapidated, obsolete, unreliable and in an appalling state of disrepair, reflecting the poor maintenance culture in the country and gross inefficiency of the public utility provider. Building on an analysis of the major shortcomings of the current electric power company, this paper presents the central issues that should form the key objectives of the proposed reform. This include corporatization of the electric power industry, increasing access and power delivery capacity, constraining the costs of the power industry and increasing efficiency and share of renewables in energy generation, as well as minimising environmental damage. We conclude with the observation that efforts at reform will not yield the desired result if the current end-user inefficiency is not constrained. As Nigeria implements its national utility privatisation programme, it is hoped that this review will benefit policy makers and emerging managers and providers of electricity service in the country.

SUMMARY Energy transition is the process whereby there is an increase in the volume and proportion of commercial energy, to the extent that it replaces traditional fuels as the main source of energy and having enormous implications for the physical and biotic environment. This energy-environment process has rarely been the focus of research investigation in Africa. Using cross-national data drawn from the African continent, this paper examines and accounts for intercountry variations in the nature and extent of the energy transition process. The empirical analysis reveals that, for the continent as a whole, the extent to which commercial energy replaces traditional fuels is quite low. It varies between 33% and 39%. However, inter-country variations were found to be as high as 90% in countries such as Algeria, Egypt, Libya, Mauritania, Morocco and South Africa; and less than 15% for such countries as Benin, Burkina Faso, The Central African Republic, Ethiopia, Lesotho and Uganda. The key factors explaining...

PurposeThe UK construction industry produces up to one third of all waste to landfill. This study aims to identify specific project practices impeding the reduction of waste in construction projects as well as uncovering potential waste solutions throughout the project delivery process. The rationale being that for such a drastic reduction in waste to landfill, holistic and extensive measures would be required.Design/methodology/approachA two‐way methodological approach was used. This comprised qualitative unstructured interviews and a quantitative questionnaire survey of three major stakeholders in the UK construction industry: clients, architects and contractors.FindingsDesign factors remain the major cause of impediments to waste reduction to landfill. Critical impediments include clients making waste prevention a top priority in projects, overly complex designs, waste taking a low priority compared to project time and costs, lack of concerns by designers for buildability, among others. Critical solutions include early supply chain involvement in design process, choosing materials for their durability, early communication of design changes to all parties, longer project programmes and better lead times, among others.Practical implicationsIn all, the target of halving construction waste to landfill based on the 2008 benchmark is achievable but would require construction companies to take it upon themselves to implement the proposed solutions suggested by this study.Originality/valueThe value of this research is to provide UK construction companies with solutions to reduce waste and aid the reaching of the landfill target, as landfill is decreasing as a solution to waste. In addition the cost savings on reducing waste could be crucial for companies in this current economic climate.

The debate about the precise role of energy in economic development remains contentious. Existing empirical studies have produced varying results: some have argued the complementarity between energy and other factors of production, and others have indicated that energy can be substituted for other factors of production. Commonly, these studies have focused primarily on the developed countries, one explanation being that supply constraints and price rigidities render any study on factor substitutions in developing countries meaningless. However, the functional relationship between energy consumption and income in developing countries is constantly investigated with the use of regression techniques. While such techniques are useful in empirical analysis, no mechanism exists for indicating causal directions between variables. This limits the scope for policy analysis and prescription. The need to identify causal direction between energy consumption and income growth in developing countries is overwhelming. Apart from providing further insights into the role of energy in economic development, it provides policy analysts with a clearer understanding of the likely impact of energy supply constraints on economic growth. This article examines the causal directions between energy consumption and economic growth (proxied by GDP and GNP) for Nigeria and Tanzania. The results show a simultaneous causal relationship between energy and economic growth for both countries, the implication being that, unless energy supply constraints are eased, economic growth and development will remain elusive to these countries. Given similar economic characteristics and profiling the same energy scenario for other developing countries, our finding supports the view that energy plays a key role in economic development.

Shortages in commercial energy (gas, fuel oil, electricity and kerosene) supplies have become increasingly marked in Nigeria, and this has been graphically illustrated by incessant power failures. Primarily such shortages have been created by unprecedented increases in energy use derived from the growth in demand for consumer goods such as electrical equipment and motor vehicles, in addition to a huge expansion of the services sector and light manufacturing following the oil boom of the 1970s. The long-run implications of such demand increases were not fully appreciated or adequately forecast because of the general feeling that Nigeria had the privileged position of being a net oil exporter and producer of gas. However, the reality of energy shortages has led to the consequences of lost output and restrictions placed upon the further expansion of the service sector. With little hope of a short-run solution to the problem, a long-term view needs to begin by acquiring a comprehensive knowledge of the energy consumption behaviour of the household sector as an input into a more wide ranging energy plan for the country. This article focuses on how such knowledge can help achieve this objective.

SUMMARY The concept of sustainable development should be familiar to those who have had to contend with development issues in the developing world. This concept first emerged in the latter part of the 1960s because of the increasing frustration felt by policy makers regarding the proliferation of failed grandiose and ambitious development programmes and abandoned ‘white elephant’ projects in Africa and other developing countries. Consequently, ‘sustainable growth’ was to form the cornerstone of development programmes. Gigantic ‘white elephant projects’ that often overshoot budgets and cease to be operational with the ending of development assistance were abandoned. However, the current broader understanding of sustainable development does have a very strong environmental theme. It is gradually becoming apparent that an unqualified growth, measured by increases in gross domestic product, which is then used as proxy for development is contradictory. Given the present situation where more than 1 billion peop...

SUMMARY The authors question Africa's ability to achieve sustainable development in view of the erosion of its institution building capacity, a problem compounded by the alarming rate of Africa's continuing marginalisation in the world economy. The situation has been provoked by inappropriate domestic policies which have not only compromised Africa's competitiveness, but also made it particularly vulnerable given the increasing globalisation of markets and factors of production. The benefits associated with effective global economic participation transcend direct financial gains and include technology transfers, technical and managerial skills transfers, and other skills transfers associated with the ‘learning and doing’ process. These benefits are instrumental in the development of the economic, administrative, legislative and social institutions that prescribe the organisational and managerial structure of an economy and define its capacity for sustainable growth. In Africa, the absence of such structur...
