Discrete choice modelling of willingness to pay for facility retrofitting: a multinomial logit model approach Njideka Maryclara Aguome, Nonso Izuchukwu Ewurum, Fidelis Ifeanyi Emoh Journal of Facilities Management, 2025 Purpose The global imperative for sustainable infrastructure management has intensified the focus on facility retrofitting as a key strategy for reducing environmental impact and enhancing operational efficiency. However, the complex interplay of factors influencing stakeholders’ willingness to pay (WTP) for such interventions remains inadequately understood, impeding effective policy formulation and resource allocation. This study aims to examine the motivational factors influencing the adoption of green retrofits in Lagos, Nigeria. Design/methodology/approach This study used a stated preference discrete choice experiment conducted with 425 decision-makers of corporate facilities in Lagos, Nigeria. A multinomial logit model was used to compare retrofitting choice sets and a status quo option. Findings The study revealed that education level, reputation concerns, income, incentives and corporate social responsibility awareness significantly predicted WTP for basic heating ventilation air-conditioning, and lighting upgrades. Regulatory compliance, awareness, education, income and reputation emerged as key drivers for more comprehensive retrofits incorporating renewables. Practical implications The research findings, by revealing which motivators resonate strongest, offer an evidence-based roadmap that directs practitioners to look beyond price incentives and emphasize complementary non-price interventions integrated with policy. The study’s emphasis on the significance of noneconomic WTP drivers equips program administrators with actionable strategies to optimize the uptake of retrofits based on individuals’ motivational structures. Originality/value This is one of the very few studies that have investigated the motivational factors influencing the adoption of green facility retrofitting in emerging markets, focusing on Lagos, Nigeria.
Housing preferences of older adults in Nigeria’s emerging real estate market: a taxonomic analysis Nonso Izuchukwu Ewurum, Nnamdi David Ehiemere, Nkiruka Obi-Aso Housing Care and Support, 2025 Purpose This study investigates the housing preferences of older adults in Nigeria’s evolving real estate market, emphasizing the growing social sustainability gap driven by population aging, housing delivery challenges, property management services and cultural considerations. This study aims to inform strategies that enhance health, well-being and social sustainability for this demographic, integrating property management and cultural factors into housing solutions. Design/methodology/approach A cross-sectional survey was conducted with 120 Nigerian adults aged 65 and above. Data were collected with structured questionnaire and interviews and analyzed using nonparametric Mann–Whitney U tests. Findings Findings show strong preferences for health and safety features such as bathroom safety modifications, disability-friendly designs, accessible transportation and proximity to amenities. Property management services, such as responsiveness and senior-focused decision-making, and cultural preferences like multigenerational living, were also significant in shaping housing choices by gender and age. Practical implications The taxonomic breakdown of housing preferences offers valuable guidance for urban planners, housing providers and policymakers in designing age-appropriate, culturally relevant and service-integrated housing solutions that promote social sustainability and improve quality of life for older adults. Originality/value This study offers new insights into the intersection of housing, aging, property management and culture in emerging markets, providing strategies to address socioeconomic challenges.
UNCERTAINTY IN PROPERTY VALUATION: ALEATORIC AND EPISTEMIC CHALLENGES IN THE NIGERIAN REAL ESTATE MARKET Nonso Izuchukwu Ewurum, Njideka Maryclara Aguome, Cezary Kowalczyk, Ikechukwu William-Johnson Ozigbo, Jacek Kil Acta Scientiarum Polonorum Administratio Locorum, 2025 Motivation: Real estate markets, particularly in emerging economies such as Nigeria, are subject to significant uncertainties. These can be broadly categorized into aleatoric uncertainties, which arise from inherent market variability, and epistemic uncertainties, which arise from incomplete knowledge and data gaps. Traditional valuation models often struggle to fully capture these uncertainties, making property investment decisions more challenging. Aim: This study aims to explore the integration of credal networks and confidence boxes (c-boxes) as an innovative approach to modeling uncertainty in real estate markets. The research focuses on the property market in Enugu, Nigeria, and demonstrates how this methodology improves the accuracy and reliability of market valuations compared to conventional probabilistic models. Approach: Combining ex post facto analysis with expert surveys, the study applied a hybrid model incorporating credal networks and c-boxes to quantify both aleatoric and epistemic uncertainties. Empirical validation was conducted on property valuation data from the Enugu market, using Monte Carlo simulations and probabilistic sensitivity analysis to assess the model’s robustness. Results: The findings revealed significant aleatoric uncertainty in property value appreciation and construction costs, while epistemic uncertainty was more pronounced in rental yields and mortgage rates. The credal network approach outperformed traditional models, providing an average improvement of 24.09% in valuation accuracy and reliability, thereby offering a more comprehensive framework for decision-making in property markets.
Brokerage performance drivers amongst married working women in an emerging real estate market Nkiruka Evangeline Obi-Aso, Nonso Izuchukwu Ewurum, Ijeoma Clara Ewurum Property Management, 2024 PurposeA perusal of extant literature suggests asymmetric devotions in empirical research that overlooks unique social and industrial dynamics of married working women in highly competitive male-dominated industries. Drawing on the social role theory, the study addressed this asymmetry by proposing a multivariate regression model that examined performance drivers of married female real estate brokers, as mediated by organizational, cognitive and social influences.Design/methodology/approachThe study employed a descriptive design. A structured electronic questionnaire was used to collect data from a sample of 256 married female brokers who are active on online messaging platforms. Snowball sampling was used to reach the research participants. Collected data were subjected to multivariate regression analysis.FindingsThe results infer that social influences were the most significant drivers of married female brokers in the real estate industry (r = 0.932, p < 0.05, F = 556.581). Significant interventions of diversity management, work-life balance, family support and access to economic opportunities were found.Practical implicationsIn acknowledging the societal stereotype and culturally imposed burdens married women face in emerging economies, the study advanced theoretical, practical and policy initiatives for a more inclusive, supportive and learning-oriented work environment.Originality/valueThe novelty of the paper lies in its exposition of the unregulated real estate brokerage market in an emerging economy and the dynamic organizational, cognitive and societal influences of married female brokers.
Underlying Anthropogenic Driving Factors of Forest Landscape Degradation in the Kilimanjaro World Heritage Site, Tanzania Using Survey-based Data E. A. Enoguanbhor, G.O. Chukwurah, E. C. Enoguanbhor, M.O. Isimah, A. E. O. Kosun, et al. Nature Environment and Pollution Technology, 2024 This study aimed to investigate the underlying anthropogenic driving factors of forest landscape degradation in the Kilimanjaro World Heritage Sites (WHS), Tanzania using survey-based data. The essence is to support strategic policies for forest landscape protection and natural heritage sustainability. The research employed empirical data using mixed questionnaires of experts and residents to identify various indirect anthropogenic driving factors of forest degradation, analyze rural poverty and causal mechanisms as indirect anthropogenic drivers of forest degradation, and evaluate the level of awareness and community involvement in forest protection. ArcGIS was used to generate the Maps. About 140 sample sizes were utilized for this study. Using purposive and simple random techniques, about 46 and 100 mixed questionnaires were distributed to experts in forest guard and residents, respectively. Data were analyzed using quantitative and qualitative techniques. Findings showed that indirect factors of forest degradation include high tourism demand, poverty, culture and tradition of local communities, lack of forest protection and conservation education, and insufficient land availability. Also, findings showed that rural poverty as an indirect anthropogenic driving factor of forest degradation is attributed to unemployment in rural areas, inadequate land for agriculture, and insufficient productive forestry availability. Additionally, this study revealed that residents are aware that the forest is under the government’s protection, and most people in local communities are not involved in activities for forest protection. Therefore, the study suggests that the locals should be involved in the activities that promote forest protection for effective control and management. Alternative heating methods should also be explored to reduce much pressure on the available forest to improve the natural heritage sustainability of natural WHS found in Sub-Saharan Africa and other parts of the Global South.
