In less than a decade to sustainable development goals (SDGs) there is a threat of household waste emanating from sub-urban sprawl especially in developing countries. Private approaches with government-enabling environments have been proved a successful platform for urban services such as housing provision and telecommunication in developing cities. Still private solid waste management (PSWM) seems different in Nigeria. Therefore, this paper aims to investigate the possible perceived hindrances facing PSWM organisations and proffer feasible policies to enhance sustainable clean and healthy cities.

Seven communities within Benin City sub-urban environs were adopted as the study area to accomplish the research’s objectives via a phenomenology type of qualitative research design. The study analysed the collated data from the knowledgeable participants via a thematic approach.

Lax legislative, absence of institutional framework, inadequate economic motivation, inadequate technical operations, among others, emerged as the encumbrances faced by PSWM firms. Wastes dumped along unethical locations such as streets, roads, uncompleted buildings, culverts and drainage channels, and undeveloped plots emerged as the encumbrance outcomes. Findings show that proffering feasible policy solutions to tackle identified hindrances can promote the achievement of SDGs across semi-urban locations in Nigeria.

This research is restricted to urban household waste management by PSWM within Nigeria. Also, the study identified the challenges and proffer policy solutions to enhance improved clean environment within the sub-urban and urban cities.

As part of this study’s implications, results from this research intend to guide government policymakers and PSWM firms to encourage collaboration in designing appropriate strategic and educational programmes for the householders (customers) in sub-cities. It will be achieved via feasible policies that are tailored towards achieving sustainable health and environment-friendly sub-urban locations.

This paper intends to enhance proper PSWM and create sustainable cities via collaboration. Also, the paper engaged key stakeholders via a qualitative research design to proffer possible solutions to the menace of sub-urban and urban household waste management.

The organised self-help approach successfully enhances urban low-income earners' (LIE) homeownership in some developing countries. The technique can enhance urban resilience for sustainable LIE homeownership. There is a paucity of studies concerning sustainable homeownership for Nigeria's urban LIE through a self-help approach. The study investigated the housing needs of the urban LIE via organised self-help mechanisms and how the same can enhance urban resilience for sustainable homeownership in the Ancient City of Benin, Nigeria.

Given the unexplored nature of the issue, 20 face-to-face interviews were conducted with experts and analysed through a thematic approach.

Findings identified eleven main barriers faced by the urban LIE. This includes the absence of government housing policy, funding frameworks, urban land scarcity, high property development costs, naira devaluation, high-interest rates, inflation, bribery and corruption, lax mortgage sub-sector, high cost of infrastructure, and government bureaucracy.

This study will contribute to pioneering the role of organised self-help mechanisms in urban resilience for sustainable LIE homeownership in developing cities via a qualitative approach. Also, findings would significantly contribute to developing countries' sustainable housing and urban resilience literature.

Several studies have shown that climate change is a threat to sustainable human living and high consumption of energy by buildings is a contributory factor. However, green practices in buildings have been proved as one of the successful technologies to mitigate global warming. Previous studies have shown lax green practices in developing countries’ buildings, but how far concerning green certification of buildings in Nigeria is yet to be explored. Therefore, this paper investigated the barriers to green certification of buildings (GCB). Also, the paper proposed a model for promoting GCB in Nigeria.

Eighteen experts with green building certification knowledge were engaged across three of Nigeria’s cities (Benin City, Abuja and Lagos) via scheduled WhatsApp video and teams calls. Collated interview data were analysed and presented in themes.

Findings show that there is an absence of a framework to promote GCB in Nigeria. Hence, GCB is low across the states. Twelve main sub-themes emerged as the barriers to GCB in Nigeria. Also, eight key sub-themes emerged as the possible concepts that can be used to improve GCB in Nigeria and formulated into a proposed framework to promote GCB in Nigeria.

This paper is limited to GCB in Nigeria and only 18 participants were engaged. Thus, this paper suggests that a mixed-methods approach should be conducted in future studies with wider coverage. This may assist to validate the paper’s findings.

Findings from this paper will stir up practitioners in green building and influence the promotion of GCB in the sector. As part of this study’s implications, suggestions through the paper’s proposed framework will benefit Nigeria’s policymakers to make decisions towards achieving GCB. This can be achieved via the proposed framework to promote the concept across Nigeria.

This paper is probably the first that attempted to investigate the barriers and proffer policy solutions via a framework to promote GCB in Nigeria and by extension in other developing countries.

Studies have proved that wood sawmill workers are exposed to high occupational risks if not well managed. In developing countries, many wood sawmills are found in urban and semi-urban areas. Studies exploring how residents near these wood sawmills perceive and react to these risks is scarce in Nigeria. The application of the fourth industrial revolution (4IR) technology is possibly one of the ways to manage the likely hazards. This study aims to investigate the possible hazards associated with timber sawmills in residential areas and the role of 4IR technologies in proffering feasible solutions to mitigate them in Nigeria’s cities.

Data were sourced from three cities and nine sawmills across Nigeria. Face-to-face interviews were conducted with authoritative participants (residents, environmentalists, government agencies, sawmill owners, 4IR technology experts and medical experts) who have been championing the regulation and safety of timber sawmill locations within the cities (Lagos, Benin City and Owerri) via a phenomenology type of qualitative research and supplemented by secondary sources.

Findings show that timber sawmills are located across the three cities in Nigeria and may have contributed to the health and environmental challenges of the people living in the neighbourhood. The identified hazards were grouped into three sub-themes (physical, health and environmental hazards). Findings identify robots, modularisation, cyber-physical systems, the internet of things and services and human-computer interaction as the digitalised technology that can be used in sawmills to mitigate hazards for the benefit of mankind.

The paper is limited to hazards that residents in timber sawmills locations may face in Nigeria’s cities and data collected via face-to-face 23 interviews. The paper’s referral to past publications in the findings and discussion section compensated for the small sample size.

As part of this paper’s implications, the emerged recommendations will strengthen collaboration with relevant stakeholders regarding control measures via the use of 4IR technologies in timber sawmills. This will stir up policymakers to develop possible policies that will promote and create the platform for the implementation of 4IR technologies in city sawmills.

Apart from probably being the first paper to explore the hazards of residents in timber sawmill locations and proffer solutions via the usage of the 4IR technology, this paper’s contribution emphasis the need for in-depth future studies regarding the risk perceptions of Nigeria’s residents living in timber sawmill area.

The high consumption of energy by buildings may have enhanced land degradation, flooding, air pollution and many other hazardous environmental issues. However, green practices in buildings have been proved as one of the successful technologies to mitigate these issues. Past studies have shown lax green practices in Nigerian buildings. Concerning public hospital buildings, this is yet to be explored. Therefore, this paper aims to investigate the barriers to green practices and proffer possible policy solutions to promote hospital green buildings.

In attaining these objectives, the view of hospital building contractors, design team, hospital management and policymakers in the relevant ministries/agencies was engaged via virtual interviews. The collated data were analysed and presented in the thematic pattern.

Findings show that green building construction is extremely low in Nigeria, but the worst hit is the health-care buildings across the states. Government/policy-related, organisational/leadership-related, financial-related, technical-related, design team-related and stakeholders’ behaviour-related barriers emerged as the main six themes of barriers affecting public hospital green buildings implementation initiatives. Findings show that proffering possible policies to addressing these barriers may improve public hospital green construction across the states.

This paper is limited to barriers to green buildings implementation in public hospitals in Nigeria, and data collection was through virtual interviews but does not affect the strength of the findings. Thus, this paper suggests that the sub-themes and variables/items that emerged from the collated data as presented in Figure 1 can be further developed quantitatively via questionnaire survey to validate and improve the reliability of results from this paper.

As part of this study’s implications, suggestions from this paper will stir up policymakers’ decisions, to be tailored towards achieving green buildings implementation initiatives in Nigerian public hospitals.

To the best of the authors’ knowledge, this paper is probably the first that attempted to investigate the barriers to green buildings implementation in public hospitals in Nigeria.

Being Igbo is synonymous with being enterprising. This is perhaps the most popular impression that many people have about the Igbo of south-eastern Nigeria. Historical antecedents indicate that prior to colonisation, the Igbo engaged actively in trade and agriculture. However, the events of the Nigeria Civil War (1967–1970) had an indelible impact on the economic activities and achievements of the Igbo. Since then, this ethnic nation has risen from economic ashes, and evidence abound in different commercial spaces across the globe. A critical driver of this economic renaissance is the Igba-Boi/Imu Ahia traditional business apprenticeship model. Founded on the Igbo philosophies of communality, co-prosperity and interdependence, the model is characterised by the transgenerational transfer of entrepreneurial skills and the reproduction of business champions. In this chapter, we assess the centrality of enterprise in the Igbo culture; appraise entrepreneurial activities of the Igbo during the pre-colonial and colonial periods; discuss the consequences of the Nigerian Civil War (1967–1970), as well as the post-civil war economic revival. Specifically, we analyse the processes, opportunities and challenges of the Igbo traditional business apprenticeship. Broad-based recommendations highlight imperatives for sustainability and leveraging across cultures and contexts.

It is January 2017, and Nikki Tyler, market access advisor at the U.S. Agency for International Development's Center for Accelerating Innovation and Impact, must recommend an actionable strategy for how to use the $10 million contributed by global donors and foundations to scale up the use of chlorhexidine in Nigeria. It was clear that chlorhexidine, a substance applied to newborns' umbilical cord stumps to prevent infection, could reduce infant mortality significantly. However, changing behavior would be an enormous challenge. This case gives students an appreciation for the importance and complexity of global health issues, along with an understanding of key analytic techniques for approaching a complex market situation. Students quickly learn that there are no easy answers to encouraging chlorhexidine's greater use. To develop a plan, it is essential to complete detailed analyses, study insights and motivations, and ultimately compare different possible solutions, considering efficiency and efficacy.

The purpose of this paper is to examine realtors and residents’ perceptions of the effectiveness of Crime Prevention through Environmental Design (CPTED) in reducing night-time and daytime break-ins in residential estate.

The study adopted case study methods. Two residential estates (one at inner and the other at outer city) were selected as cases of the study. Data were collected from two sets of respondents: realtors and tenants. In the realtors’ cluster, all real estate and property development companies were sampled since the population is very small. Systematic sampling technique was used to select residents. Respondents were asked to answer closed-ended questions on socio-economic and demographic characteristics, perception of property crime, spending on CPTED and effectiveness of CPTED. Data were analyzed using the descriptive and inferential statistics.

Findings disclose that more than half of the residents of inner and outer city had been victims of housebreaks and these incidences are expected to increase in the nearest future. To reduce break-ins, findings show that realtors and residents have spent on both formal and informal surveillance with emphasis on ensuring visual control over premises. Furthermore, respondents confirm the effectiveness of CPTED in deterring break-ins. The study establishes variation in the realtors and tenants’ perception of break-ins as spending on CPTED strategies vary between them, with locations and types of properties.

Social and human factors remain very important as far as the prevention of break-ins is concerned. These should be taken into considerations when improving CPTED approach in the future. Besides, adequate attentions should be given to daytime break-in. Nonetheless, night-time break-ins should not be neglected. Furthermore, the study emphasizes the importance of visible, clean and well-lit premises as ways of reducing break-ins. It is therefore suggested that residential properties should be well lit at nights, while CCTV and security personnel be positioned in strategic places and within security viewing range so as to send fast alerts to the nearest police stations in the cases of break-in(s).

Very few studies on effectiveness of CPTED have mainly concentrated on how CPTED works in residential estates. No study till date, have explored how realtors perceive CPTED in preventing break-ins. Besides, this study contributes to existing literature having revealed variation in the realtors and tenants’ spending on CPTED on the basis of property location and types of residential properties.

The purpose of this paper is to examine the critical factors that shape the green purchasing behaviour (GPB) of nursing mothers in their choice of baby diapers. The study also investigates demographic influences on GPB.

Purposive and convenience sampling methods were used in selecting 150 respondents for the study. Questionnaires were administered to nursing mothers in University of Benin Teaching Hospital and Creches within Benin City, Nigeria. A total of 124 questionnaires were returned, out of which 116 (77 per cent) were found usable. The data collected were analysed using mean, factor analysis and analysis of variance.

Results reveal that environmental attitudes and perceived effectiveness of environmental behaviour are the critical predictors of GPB of nursing mothers in the selection of diapers. Age was the only demographic that significantly explain nursing mothers’ GPB.

International green marketers planning to offer baby diapers in Nigeria should seek to influence nursing mothers’ attitude by emphasizing the perceived effectiveness of their GPB. In the same vein, the municipal waste management in conjunction with the post-natal and child healthcare needs to educate nursing mothers of the danger of improper disposal and selection of non-degradable diapers.

The study is unique and seminal in nature, as it is first of its kind possibly in Nigeria to examine the GPB and environmental sensitivity of nursing mothers in the selection of baby diapers.

The prevalence of overweight and obesity in children and adolescents is on the increase in developing countries. Therefore, a cheap, accessible and simple screening tool such as the mid-upper arm circumference (MUAC) is required for the prompt assessment. The purpose of this paper is to determine the usefulness of MUAC in assessing overnutrition in comparison with bioelectrical impedance analysis (BIA).

Participants included 1,067 children aged 6–18 years recruited from private and public schools in Egor Local Government Area in Benin City, Nigeria. Body fat was estimated by BIA using a Tanita scale, whereas the MUAC was measured with a non-elastic tape. Receiver operating characteristic analysis was used to test the ability of MUAC to determine children and adolescents identified as overweight and obese by BIA.

The prevalence of overnutrition by MUAC (12.4 percent – overweight 6.0 percent and obesity 6.4 percent) was comparable to that by BIA (12.3 percent – overweight 5.4 percent, obesity 6.9 percent). There was a significant correlation between MUAC and body fat percentage, fat mass, fat mass index and fat-free mass index in both males and females (p=0.000).

This study, in contrast to most other studies on the use of MUAC in the assessment of overnutrition, has the advantage of using BIA cut-offs values against body mass index which does not assess body fat composition. BIA is, however, not the gold standard in the measurement of body fat composition. The optimal MUAC cut-off values of this study may not be representative of the entire country because of its restriction to Benin. Similar studies from different parts of Nigeria will be required to validate this smoothed MUAC percentiles for use in the screening of children and adolescents for overnutrition.

MUAC compares well with BIA in this study and can be a useful, alternative and practical screening tool for assessing obesity in the resource-poor setting.
