Abstract
This study examined public perception of environmental quality for sustainable commercial property investment in the South-East Geo-Political Zone of Nigeria, with focus on Aba, Owerri, and Onitsha. The study was motivated by increasing environmental challenges associated with rapid urbanization, flooding, poor waste management, traffic congestion, and inadequate infrastructure within major commercial centres in the region. A descriptive survey research design using quantitative survey methods was adopted. Primary data were collected through structured questionnaires administered to estate surveyors and valuers, property developers, investors, residents, business operators, and environmental professionals. Out of 360 questionnaires distributed, 300 valid responses were retrieved and analysed, representing an 83.3% response rate. Descriptive statistical tools, including frequency distribution, mean score, standard deviation, and Relative Importance Index (RII), were employed for data analysis. The findings revealed that environmental quality significantly influences sustainable commercial property investment within the study area. Effective drainage systems, road infrastructure, waste management, sanitation, accessibility, and security conditions were identified as major determinants of investment attractiveness and property performance. The study further identified sustainable urban planning, green building practices, renewable energy systems, stronger environmental regulations, and public-private partnerships as essential strategies for improving environmental sustainability in commercial property development. The study concluded that improved environmental management and infrastructure provision are critical for enhancing sustainable commercial property investment in South-East Nigeria.
Purpose: This study sought to examine the influence of green procurement practices on environmental compliance in public universities in Nairobi City County, Kenya. The specific objectives were to examine the influence of green purchasing policies, supplier environmental evaluation, eco-friendly product selection, and waste reduction and recycling practices on environmental compliance.
Methodology: The target population comprised 190 officers drawn from procurement, environmental management, facilities management, and administrative functions across seven public universities in Nairobi County. Proportional stratified random sampling was used to select 129 respondents. Primary data were collected using structured questionnaires. Validity was ensured through expert review, while reliability was assessed through pilot testing procedures. Data were analyzed using descriptive statistics, correlation analysis, and multiple regression analysis, and the findings were presented in tables.
Findings: The regression results showed that the four independent variables jointly explained 75.9 percent of the variation in environmental compliance, indicating that green procurement practices are strong predictors of environmental compliance in public universities.
Unique Contribution to Theory Practice and Policy: University management and procurement departments should develop, update, and fully institutionalize comprehensive green purchasing policies that explicitly integrate environmental criteria into procurement planning, specification development, tendering, and contract management.

This study investigates the challenges associated with stakeholder management in Nigerian
property development, using the Boing Mega City Project in Rivers State as a case study. The
study adopts a mixed-methods case study research design, integrating quantitative and
qualitative approaches to provide both breadth and depth of analysis. The study population
comprised project developers and professional staff of Boing Estates, home buyers, realtors,
and community leaders, with a total population of 1,980 stakeholders. Using purposive and
stratified random sampling techniques, a sample size of 333 respondents was determined
through the Taro Yamane formula at a 5% margin of error. Primary data were collected
through structured questionnaires and semi-structured interviews, while secondary data were
sourced from government documents, project records, academic literature, and industry
reports. Quantitative data were analyzed using descriptive statistics, including mean scores
and Relative Importance Index (RII), with SPSS version 25, while qualitative data were
thematically analyzed. The findings reveal that residents and end-users, community leaders,
and government agencies are the most critical stakeholders in the Boing Mega City Project,
highlighting the centrality of social acceptance and institutional support in mega property
developments. Key challenges identified include conflicting stakeholder interests, weak
institutional frameworks, and political interference, alongside limited financial resources and
socio-cultural resistance. These challenges were found to undermine coordination,
transparency, and effective engagement, thereby affecting project implementation and
sustainability. The study concludes that improving stakeholder management in Nigerian
property development requires stronger institutional coordination, transparent and inclusive
engagement processes, adequate resource allocation, and culturally sensitive strategies.

This study examined the organisational and regulatory factors influencing the adoption of environmental sustainability practices in selected petroleum industries in Southeast Nigeria. The petroleum sector remains economically important, but its operations are associated with environmental concerns that require stronger sustainability responses. A cross-sectional survey research design and quantitative approach were adopted. Primary data were collected through a structured questionnaire administered to employees and management personnel in selected oil and gas companies. A total of 420 questionnaires were distributed, 392 were retrieved, and 384 valid responses were used for analysis, representing a valid completion rate of 91.4%. Data were analysed using descriptive statistics, including frequencies, percentages, mean scores and standard deviation, as well as multiple regression analysis. The findings showed high agreement with organisational factors, regulatory factors and environmental sustainability adoption, with mean scores of 4.23, 4.07 and 3.95, respectively. The regression results indicated that organisational factors had a significant positive effect on environmental sustainability adoption (β = 0.45, t = 9.62, p < 0.05). Regulatory factors also had a significant positive influence on adoption (β = 0.37, t = 7.88, p < 0.05). The model explained 58.0% of the variation in environmental sustainability adoption. The study concludes that internal organisational support and consistent regulatory oversight are important for improving sustainability practices in petroleum firms.

This study assessed the effectiveness of environmental protection and management systems in promoting environmental sustainability in Kigali City, Rwanda. A mixed-methods research design was employed to examine the contribution of environmental policies, institutions, implementation mechanisms, and stakeholder participation to sustainable environmental outcomes. Quantitative data were collected from 400 household respondents selected through stratified random sampling across the districts of Gasabo, Kicukiro, and Nyarugenge, while qualitative data were obtained from purposively selected key informants, site observations, and document review. The sample size was determined using Yamane’s formula. Quantitative data were analysed using descriptive statistics, specifically frequencies and percentages, and presented through tables and figures, while qualitative data were analysed using thematic content analysis to identify key patterns and perspectives. The findings revealed that Rwanda has established comprehensive environmental policies, regulations, and institutional frameworks that have significantly contributed to environmental sustainability in Kigali City. Environmental protection and management systems have improved environmental outcomes through effective waste management, green urban planning, environmental impact assessments, wetland restoration, biodiversity conservation, and community participation. These interventions have enhanced environmental conservation and supported sustainable urban development. However, the study identified several challenges limiting effectiveness, including inadequate funding, weak enforcement of environmental regulations, limited technical and institutional capacity, insufficient community participation in decision-making, and coordination gaps among stakeholders. The study concludes that environmental protection and management systems have made substantial contributions to environmental sustainability in Kigali City, although implementation and governance challenges continue to constrain their full effectiveness. It recommends strengthening environmental law enforcement, enhancing institutional coordination, increasing financial and technical support, and promoting participatory and sustainable urban planning practices to improve long-term environmental sustainability.

Water privatization is a contentious policy response to scarcity in semi-arid regions. This study investigates its socio-environmental consequences for indigenous communities in Laikipia County, Kenya. Employing a concurrent mixed-methods design, data were collected via surveys (
n
=15 community members), semi-structured interviews (
n
=25 with government, WRMA, and commercial farm officials), focus group discussions, and document analysis. Qualitative analysis identified five dominant themes: drivers of privatization, water access and availability, perceptions of water quality, environmental change, and governance and social conflict. Findings show privatization was primarily driven by state failure, corruption, and a quest for operational efficiency. Implementation involved minimal transparency or community consultation. While commercial horticulture farms secured reliable water access, indigenous communities faced significantly reduced water availability. 67.7% reported increased challenges, and 67.7% reported deterioration in quality, including elevated turbidity and chemical contamination from agricultural runoff. There was also greater unaffordability. Environmental externalities included river depletion (Figure 1), groundwater over-extraction, and pollution. These issues exacerbated ecological precarity. The process transferred control from communal to private hands, fueling social conflict and eroding local governance. The study concludes that neoliberal water governance, as implemented in Laikipia, prioritizes commercial efficiency over equity and ecological sustainability. This disproportionately burdens indigenous populations. Findings are subject to limitations, such as a small community sample size and the absence of longitudinal hydrological monitoring. We recommend policy reforms centred on mandatory community co-management, robust environmental impact assessments, and hybrid public-communal governance structures. These can help ensure water justice and long-term resource security.

Urban recreational centres constitute an important component of sustainable urban development by providing
ecosystem services, leisure opportunities, social interaction, and environmental benefits. However, increasing urbanization and
population growth have intensified environmental pressures on these facilities, particularly in rapidly expanding cities such as
Abuja, Nigeria. This study assessed the environmental threats associated with the utilization of recreational centres and
examined the role of urban planning in promoting sustainable recreational centre management in the Federal Capital City
(FCC) of Abuja, Nigeria. A mixed-method research design was adopted, integrating quantitative and qualitative approaches.
Primary data were collected through questionnaires administered to 462 recreational park users, semi-structured interviews
with key stakeholders, and Focus Group Discussions (FGDs) involving urban planners, environmental experts, park managers,
and community representatives. Descriptive statistics, Chi-square analysis, and the Kruskal-Wallis H test were employed to
analyze the data. The findings revealed widespread public awareness of environmental degradation across recreational parks,
with major threats including soil erosion, air pollution, noise pollution, improper waste disposal, vegetation loss, water pollution,
and disturbances to biodiversity. Visitors attributed these threats primarily to poor facility management, inadequate
environmental education, negligence by authorities, and insufficient waste management infrastructure. The Kruskal-Wallis H
test showed no statistically significant differences in environmental threat perceptions across Commercial/Amusement Parks,
Large Formal Parks, and Neighborhood Parks (p > 0.05), indicating that environmental degradation is perceived as a city-wide
challenge rather than a site-specific issue. Furthermore, demographic variables such as age, gender, education, income, and
marital status were found to have no significant influence on awareness of sustainable environmental practices, suggesting that
sustainability awareness is broadly distributed across the population. However, occupation showed a significant association with
awareness levels in Commercial/Amusement Parks (χ² = 16.036; p = 0.042). The study concludes that while sustainability
awareness among park users is relatively high, environmental degradation persists due to weak governance structures,
inadequate policy implementation, poor maintenance culture, and limited stakeholder participation. The study recommends the
adoption of an integrated city-wide recreational sustainability framework, strengthened institutional coordination among
relevant agencies, enhanced environmental monitoring, and a shift from awareness-focused interventions to action-oriented
policies that facilitate sustainable environmental behaviour. These measures are essential for ensuring the long-term
sustainability of recreational centres and their contribution to urban environmental quality in Abuja.
