Foodborne bacterial disease remains a major public-health burden, and ready-to-eat (RTE) foods are a recognised vehicle for pathogens where hygiene is inadequate. This study isolated, molecularly characterised and profiled the antibiotic resistance of foodborne bacterial pathogens from campus food outlets in polytechnics in South-West Nigeria. An experimental laboratory design was used. RTE foods and food-contact surface swabs were collected from purposively selected outlets, isolates
were cultured on selective media and confirmed by 16S rRNA sequencing, and susceptibility was tested by Kirby-Bauer disc
diffusion. A total of 60 food samples and 40 surface swabs yielded 142 isolates: Escherichia coli (28.2%), Klebsiella pneumoniae (18.3%), Staphylococcus aureus (16.9%), Salmonella spp. (12.7%), Shigella spp. (9.9%), Pseudomonas aeruginosa (7.7%) and Listeria monocytogenes (6.3%). Multidrug resistance occurred in 62.4% of isolates, highest in E. coli (78.6%) and K. pneumoniae (72.3%). Resistance was most frequent against amoxicillin-clavulanate (83.3 to 92.5% across species), tetracycline (66.7 to 82.5%) and co-trimoxazole (66.7 to 77.5%). Resistance genes detected included blaTEM (68.4% of E. coli), blaCTX-M (42.1%), tetA (57.9%) and sul1 (63.2%). Campus food outlets harbour multidrug-resistant pathogens, including WHO highpriority organisms, which supports food safety and antimicrobial stewardship interventions.

The indoor environment in which students learn affects their health,
comfort, attendance and performance. This study assessed indoor air
quality, thermal comfort and ventilation performance in learning spaces
of polytechnics in South-West Nigeria and related them to occupant
perception. A field-measurement and survey design combined physical
monitoring in 18 classrooms, lecture halls and studios with a validated
survey of 480 occupants. Mean carbon dioxide concentration was 1,486
ppm, exceeding the 1,000 ppm threshold in 68.4% of measurements.
Mean PM2.5 was 42.6 µg/m³, exceeding the WHO guideline of 15
µg/m³ in 72.8% of measurements. Thermal discomfort was reported by
62.4% of occupants, with a mean predicted mean vote (PMV) of +1.24
and predicted percentage dissatisfied (PPD) of 38.6%. The mean air
exchange rate was 2.4 ACH against a recommended 4 to 6 ACH, and
only 27.8% of spaces met the recommendation. Occupant perception
correlated significantly with measured conditions, and occupancy
density, ventilation rate and building age explained 58% of the variance
in carbon dioxide concentration. The study provides an empirical
baseline and evidence-based recommendations for improving
ventilation, reducing occupancy density and enhancing thermal comfort
in Nigerian polytechnic learning environments.

Electronic waste is among the fastest-growing waste streams, and in
Nigeria much of it is handled informally through methods that release
hazardous substances. This study assessed electronic waste generation
and toxic exposure pathways in polytechnics in South-West Nigeria and
developed a sustainable e-waste recovery framework. A mixed-methods
assessment-and-development design was used, combining an inventory
of e-waste, sampling of soil, water and air at handling points for heavy
metals, surveys and interviews on awareness and management, and
expert appraisal of the framework. The six polytechnics generated 41.5
tonnes of e-waste annually (mean 6.9 tonnes per institution),
comprising computers (33.3%), laboratory equipment (24.6%),
workshop equipment (18.3%), peripherals (13.9%) and other
electronics (9.8%). Handling was predominantly unsafe: 54.2% was
stored indefinitely, 25.0% disposed of with general waste and only
2.1% formally recycled. Lead exceeded guidelines in 72.2% of soil
samples and 83.3% of water samples. Awareness of e-waste hazards
was low (25.8%), and 79.2% of units had no management policy. The
framework (collection and segregation, safe storage, reuse and
refurbishment, materials recovery, and institutional arrangements) was
rated highly by experts for feasibility (3.60), sustainability (3.80) and
health protection (3.80). The study provides an inventory, an exposure
assessment and a validated recovery framework for Nigerian
polytechnics.

Climate change is intensifying flooding, extreme heat and windstorms
that threaten infrastructure and operations in Nigeria. This study
assessed climate hazard exposure and infrastructure vulnerability across
polytechnic campuses in South-West Nigeria and developed a campus
climate resilience index. An assessment-and-index-development design
combined geospatial, field and survey methods. Hazards were mapped
for six campuses, exposure was assessed by geolocating buildings,
services, roads and critical assets, and vulnerability was assessed
through audit and survey of sensitivity and adaptive capacity. A
composite index was built from weighted, normalised indicators and
validated through sensitivity analysis and expert appraisal. Flooding
was the most significant hazard (24.6% of campus areas), followed by
extreme heat (18.4%) and windstorms (12.8%). Exposure was highest
for roads and drainage (62.4%), followed by buildings (48.6%) and
utilities (42.8%). Overall, 58.4% of infrastructure had low adaptive
capacity, with inadequate drainage (72.6%), poor maintenance (64.2%)
and lack of early warning systems (58.4%) as key gaps. The Campus
Climate Resilience Index (CCRI) ranged from 0.44 to 0.62 (mean 0.53).
Experts rated it highly for robustness (3.60), relevance (3.80) and
usability (3.40). The study provides a hazard and vulnerability
assessment and a validated index to support climate resilience planning
in Nigerian polytechnics.

Campus green areas are reservoirs of urban biodiversity and providers
of ecosystem services. This study assessed the biodiversity of campus
green areas in polytechnics in South-West Nigeria and developed an
ecological restoration framework for degraded areas. A field-survey
and framework-development design was used. The green areas of six
campuses were surveyed using 120 plots (20 m × 20 m) to inventory
trees, shrubs and herbaceous plants, biodiversity was characterised
using standard diversity measures, and degraded areas and their drivers
were identified. The framework was validated through expert and
stakeholder appraisal. The campuses contained 186 plant species, with
mean species richness of 92.7 per campus and a mean Shannon-Wiener
diversity index of 2.84. The most abundant tree species were Terminalia
catappa (18.4%), Azadirachta indica (14.6%) and Mangifera indica
(12.2%). Overall, 31.8% of green areas were degraded, mainly through
building development (38.4%), vegetation clearing (24.6%) and
encroachment (18.2%). Degradation reduced biodiversity support by
38.2%, carbon sequestration by 32.6% and air quality improvement by
28.4%. The framework (site assessment and prioritisation, native
species selection, restoration interventions, monitoring and evaluation,
and institutional arrangements) was rated highly for ecological
soundness (3.60), feasibility (3.40) and sustainability (3.80). The study
provides a biodiversity inventory, a condition assessment and a
validated restoration framework for Nigerian polytechnics.
