Abstract

Purpose

This paper aims to evaluate the risk factors and determines the overall risk level (ORL) of public-private-partnership (PPP) power projects in Ghana using fuzzy synthetic evaluation methodology (FSEM).

Design/methodology/approach

In this paper review of literature led to the development of a 67-factor risk list which was ranked by experts and industry practitioners through a questionnaire survey.

Findings

These factors were grouped into principal risk factors (PRFs) using component analysis and they served as the input variables for fuzzy analysis. The seven components were: Contract and Payment risks, Environmental risks, Financial and Cost risks, Legal and Guarantee risks, Operation risks, Socio-Political and Performance risks (SPR) and Tender and Negotiation risks. Study showed that the ORL of Ghanaian PPP power projects is high implying they are risky to both the public and private sectors. Fuzzy analysis also confirmed SPR as the most critical principal factor.

Originality/value

This study is significant and demonstrates that fuzzy methodology can be used as a useful risk evaluation tool and risk assessment framework for private investors, policy makers and public sector.

Abstract

In recent years, there have been calls on African countries to develop disaster governance system that recognises the complex nature of disaster events and reflects how their impact can prevent governments from achieving their development objectives. This chapter examines Ghana’s response to the calls by exhuming disaster management policies and the missing links in their implementation. This research was approached by comprehensively reviewing literature related to the subject. The review was supported by field-based interviews involving key stakeholders, some of whom are directly involved with disaster policy planning and implementation. The results show that even though there are several disaster management policies, they are fragmented and found within several institutions, a situation that has created some missing links in their implementation. For instance, poor collaboration and coordination among disaster management institutions hampered efforts towards disaster risk prevention, preparedness and mitigation which are viewed as cross-cutting themes in disaster management. Even more intriguing, critical stakeholders such as community groups who often play important roles in rescue and recovery operations and continue to render humanitarian services after official operations have ended are excluded from the everyday decision-making processes. Empirically, this chapter draws attention to how endogenous interventions that are deeply rooted in the culture of the people that could support well-crafted disaster legislations are often ignored. This chapter concludes that these missing links need to be addressed in order to make Ghana resilient to disaster.

Abstract

Purpose

Kumasi Metropolis, the second-largest city in Ghana is known to be bewildered with challenges relating to waste management. As a means of solving the waste management challenge, several suggestions are often made for the establishment of a waste-to-energy plant to manage the disposal of waste and generation of income. There have been no studies conducted to determine how economically viable such plants will be. This study aims to examine the economic viability of waste-to-energy generation in the Kumasi Metropolis to find out how economically viable such an approach will be.

Design/methodology/approach

To achieve this, a simple debt-equity ratio business model based on discounted cash flow technique was applied to estimate the internal rate of returns (IRR) as a measure of the economic viability and profitability of a modelled 50 MWH waste-energy generation plant in the Kumasi Metropolis. The analysis was performed using the RetScreen Expert Software.

Findings

The results show that the IRR and benefits cost ratio of the facility were 36% and 5.8%, respectively, indicating high levels of profitability and economic viability. The study concludes that waste-to-energy generation will be an economically viable venture in the Kumasi Metropolis.

Practical implications

It is, however, important for users of the findings of this study to take caution of the fact that the various assumptions although based on current knowledge and expert opinion may vary with time; therefore, the sensitive analysis on price and costs should always be considered. Practically, this study will contribute to solving the waste management situation in most cities, as well as generating revenue and helping close the energy deficit most developing countries are grabbling with.

Originality/value

The unique contribution of the study to knowledge is that it has professed an alternative analytical and methodological approach to measuring the financial viability of waste-to-energy plants in situations where there is none in the geographical jurisdiction of the proposed project.

Abstract

Purpose

Complying with the code of conduct by professionals in the construction industry worldwide has become a significant issue over the years. This has led to projects' failure, leading to losses to both the client and contractors. The study's objective is to identify the challenges of construction professionals in complying with their code of conduct and preventing corrupt practices.

Design/methodology/approach

Quantitative approach was used to collect empirical data by sending questionnaires to 56 construction professionals in South Africa. Data gathered were analysed through Excel statistical tool. Mean values were calculated for the quantitative data, whilst thematic content analyses were used to generate frequencies and percentages for qualitative data.

Findings

The findings indicate that construction professionals experience many unethical issues in their work duties such as inflated tender prices, overpricing the rates, tender-based kickbacks, bribes for projects, unethical methods of project execution, use of lower grade materials than specified, discrimination, among others. However, issues such as greediness, acceptance of corruption as usual practice, lack of knowledge about the code of conduct, the only way to get contracts, part of the process, and peer pressure create a challenge in complying with the code of conduct and preventing corrupt practices among construction professionals.

Practical implications

Construction professionals face many unethical and corrupt practices in their project management and execution, which they cannot overcome due to many factors. Therefore, there is the need to sensitise the professionals in the construction industry regarding their code of conduct as well as the danger associated with engaging in corrupt practices in their work and their implication on project performance.

Originality/value

The findings give an insight into the critical factors curtailing the construction professional's ability to comply with their code of conduct and be corrupt-free in their line of duty. Thus, professional associations can use the findings in guiding their members.

Abstract

Purpose

This paper analysed the motives behind farmers' savings with Rural and Community Banks (RCBs) and the effect of these savings on rice yield in the Hohoe Municipality of the Volta region of Ghana.

Design/methodology/approach

A multi-stage sampling approach was used to draw a random sample of 222 rice farmers, and a structured questionnaire was employed to collect cross-sectional data. A Likert scale was used to rank the motive behind farmers' savings while the endogenous switching regression model was used to estimate the effect of savings on rice yield.

Findings

The results of the study showed that most farmers mobilise savings to enhance farm investment which is critical to increasing rice productivity. Improved labour and fertiliser use had a positive influence on rice yield, while farm size had an inverse relation with rice yield. Further, the findings show that savings with RCBs help mobilise the necessary finance to enhance rice productivity. In terms of the treatment effect of savings, the results indicate that farmers who patronise saving products of RCBs recorded a statistically significant average yield of 1.41 Mt/ha more than those not patronising saving products from any bank.

Practical implications

While the literature on agricultural finance focuses largely on credit, this study demonstrates that savings hold significant benefits for the development of agriculture through productivity gains. The importance of this demonstration is further shown by the fact that credit access depends on the ability to save in most developing countries.

Social implications

There is a need to educate farmers about the essence of patronising formal savings products.

Originality/value

This study represents the first attempt at linking farmers' savings to agricultural productivity using an econometric methodology in Ghana. The study serves as a foundation paper and for that matter will serve as a guide to future research on savings mobilisation and agricultural productivity nexus.

Abstract

Purpose

The construction industry is an enabler of economic growth in developing countries, but its performance is governed by the professional behaviour of construction professionals. Unethical behaviour (UB) breaches codes of practice and undermines economic performance hence, ubiquitous academic attention has been given to understanding this phenomenon. This paper aims to contribute to the ensuing discourse by reporting upon the most critical ethical behaviours (EBs and UBs) of professionals in the Ghanaian construction industry (GCI).

Design/methodology/approach

The study compounded identified factors into a closed-ended questionnaire in a quantitative research strategy. Data analysis was conducted using the relative importance index and one sample t-test. To measure the reliability of the scale, Cronbach’s alpha was used, which indicated that all measured items were reliable for further analysis.

Findings

The study confirmed that professionals within the GCI are aware of the existence of UBs and revealed that the most prevalent ethical conducts exhibited, namely, level of accuracy, accountability, honesty, reliability, fairness and respect for colleagues. Common unethical conducts exhibited included: favouritism, bribery and corruption, professional negligence, falsification, fraud and overbilling.

Research limitations/implications

The study reported on the dominant ethical conduct among built environment professionals. The claims put forward in the analysis are, thus, affected by Ghana’s social, economic and political environments, which could restrict the generalization of the findings.

Practical implications

Incipient findings presented from this research will guide stakeholders to develop and device strategies that will aid alleviate persistent ethical issues within the built environment.

Social implications

The study highlights individuals’ perspectives on ethical issues persistent in the built environment. The findings suggest individuals adhere to ethical practices in a project environment by the evidence presented.

Originality/value

This pioneering study is a novel assessment on EBs and UBs of built environment professionals in the GCI. The study supplementary adds value to the literature on ethical and unethical practices. By identifying these practices, construction firms have a competitive edge in combating UB and promoting EB among built environment professionals in the GCI.

Abstract

Purpose

This study aims to assess gender-based differences on farmers’ perception of impacts and vulnerability to climate change and the implementation of adaptation strategies in the Pra River Basin of Ghana, while also providing lessons for other Sub-Saharan nations and regions with similar conditions.

Design/methodology/approach

The study used semi-structured interviews and questionnaires to collect data from 344 farmers, 64 participants in focus group discussions and 6 agriculture extension officers (key informants) from 10 districts in the Pra River Basin of Ghana.

Findings

Results showed several differences in how climate change is perceived and tackled by male and female genders. In the perception of male farmers, for example, they were found to be more vulnerable to increased temperature, and changes in rainfall and growing season, whereas female farmers on average were considered to be less resilient to floods and droughts for different reasons. Moreover, floods posed higher risks to farming than other climate change impacts. Gender roles had a significant correlation with the type of adaptation strategies practised. Men adopted agrochemicals more often than women, as an adaptation strategy.

Research limitations/implications

Gender-differentiated interventions should be incorporated in the national climate change action plan for sustainable development in a rain-fed agricultural economy such as Ghana. The study recommends several actions to promote gender equity in the assessed region.

Originality/value

This research assessed the gender differentials in climate trends, impact, vulnerability and adaptation based on primary data collected between April and May 2019 and compared the results with climate data in the basin for the period 1991–2014. It is an empirical study focused on primary data analysis obtained in loco by authors, involving approximately 400 participants.

Abstract

Purpose

Corruption continues to be a pervasive stain on the construction industry in developing countries worldwide, jeopardising project performance and with wide-ranging negative implications for all facets of society. As such, this study aims to identify and analyse the causes of corruption in the construction sector of an emerging economy such as Malaysia, as it is crucial to uncover the specific facilitating factors involved to devise effective counter strategies.

Design/methodology/approach

Following a detailed literature review, 18 causes of corruption are identified. The results of an opinion survey within the Malaysian construction industry are further reported to rank and analyse the causes. The factor analysis technique is then applied to uncover the principal factors involved.

Findings

The results indicate that all the considered causes are perceived to be significant, with the most critical causes being avarice, relationships between parties, lack of ethical standards, an intense competitive nature and the involvement of a large amount of money. A factor analysis reveals four major causal dimensions of these causes, comprising the unique nature of the construction industry and the extensive competition involved; unscrupulous leadership, culture and corruption perception; a flawed legal system and lack of accountability; and ineffective enforcement and an inefficient official bureaucracy.

Research limitations/implications

The study presents the Malaysian construction industry’s view of the causes of corruption. Therefore, the arguments made in the study are influenced by the social, economic and cultural settings of Malaysia, which may limit generalisation of the findings.

Practical implications

This paper helps stakeholders understand the root causes and underlying dimensions of corruption in the construction industry, especially in Malaysia. Recommendations for changing cultures that may be conducive to corrupt practices, and anti-corruption measures, are suggested based on the findings of the research.

Originality/value

These findings can guide practitioners and researchers in addressing the impediments that give rise to the vulnerability of the construction industry to corrupt practices and understanding the “red flags” in project delivery.

Abstract

Purpose

In developing countries, construction organizations are seeking to effectively implement green innovation strategies. Thus, this study aims to assess the importance of green innovation practices and develop a measurement model for quantifying the green innovation degrees of construction firms.

Design/methodology/approach

A mixed-methods research approach is adopted. First, an extensive literature review is performed to identify potential green innovation items, which are then used to design a preliminary questionnaire. Next, expert interviews are conducted to pilot-test this questionnaire. Subsequently, by using a convenience non-probability sampling method, 88 valid responses are collected from construction firms in Vietnam. Then, one-sample and independent-samples t tests are employed to assess the importance of green innovation practices. Fuzzy synthetic evaluation (FSE) is also applied to quantitatively compare such practices. Finally, green innovation level (GIL) is proposed to measure the green innovation indexes and validated by a case study of seven construction firms.

Findings

This study identifies 13 green innovation variables, of which several key practices are highlighted for small/medium and large construction firms. The results of FSE analysis indicate that green process innovation is the most vital green category in construction firms, followed by green product and management innovations, respectively. As a quantitative measure, GIL could allow construction firms to frequently evaluate their green innovation indexes, thereby promoting green innovation practices comprehensively. Hence, construction firms would significantly enhance green competitive advantages and increasingly contribute to green and sustainable construction developments.

Originality/value

This research is one of the first attempts to integrate various green innovation practices into a comprehensive formulation. The established indexes offer detailed green innovation evaluations, which could be considered as valuable references for construction practitioners. Furthermore, a reliable and practical tool (i.e. GIL) is proposed to measure the GILs of construction firms in developing countries.

Abstract

Purpose

Available studies on anticorruption practices in the construction industry are exploratory with a very limited theoretical basis. This paper aims to provide a solid theoretical foundation to examine situational factors that influence the corruption intentions of individuals and organizations in the construction industry.

Design/methodology/approach

This paper conducts a systematic literature review to synthesize construction management literature that suggests anticorruption practices. The identified practices are then examined using two theoretical frameworks: the fraud diamond theory and Lange’s corruption control framework.

Findings

The results of this research demonstrate how the four elements of the fraud diamond theory may trigger corrupt behavior in construction projects. The results also highlight conceptual distinctions among different means of corruption controls based on Lange’s corruption control framework. In addition, the findings of this research suggest that anticorruption practices should address (1) the incentives to act corruptly, (2) the normative means of corruption control, (3) the internal means of preventing corruption and (4) the shift in organizational culture.

Originality/value

This paper departs from prior research on corruption in construction projects by (1) identifying a large spectrum of anticorruption practices, (2) presenting a detailed theoretical interpretation of these practices and (3) viewing anticorruption practices as multidimensional constructs, which, in turn, leads to novel ways of examining these practices in construction projects.
