The issues of waste management, particularly in Lagos, Nigeria, are not unconnected to the unprecedented population increase with a poor integrative process of handling and transporting waste from points of generation to disposal, which in turn affects the healthiness of residents and the sustainability of the built environment at large. Based on this backdrop, this paper examined the household waste management logistics practice in the Lagos Metropolis. The primary data used consists of a questionnaire distributed to residents, supplemented by structured interviews with PSP operators and personal field observations. Systematic-random sampling was used to administer 694 units of the questionnaire. Findings revealed that organic (food) waste, which is mostly stored in drums, accounted for most of the generated household waste. It also revealed that transport distance and environmental attributes are the most important factors affecting the performance of waste collectors in waste management logistics. This study further revealed that PSP operational performance is far from being efficient as the volume of waste evacuated is low and the turnaround time of fleets is extremely high. Our study also revealed that transportation plays the most significant role in waste management logistics. Our study, however, recommends, among others, that the operations of waste management should not be limited to PSP operators but also involve the local government authorities, while improved quality of transport options and route optimization are recommended mechanisms for mitigating logistics weaknesses in waste management practices.

However, the sustainability of this approach to solid waste management has been sparsely investigated in the study area. This paper reviews composting case studies in Nigeria with the aim of providing information on its economic, social and environmental sustainability. Five composting projects were purposively selected, and information on them were sought through direct observation, interview and from journal articles, magazine and research thesis; and were qualitatively analysed. It is evident from the study that composting holds great potentials for sustainable waste management practice in Nigeria, however, its limited application in the country still undermines benefits. Consequently, the paper recommends among others data management on solid waste by relevant agencies and stakeholders, and formulation of a national policy focusing on proper integration of compos...

Unfortunately, the obvious decline in the traffic survey on Nigerian urban roads has left the road transport system to be handicap of traffic data, quality service deliveries and characterized by traffic-related quagmires with devastating socio-economic consequences including congestion, crime and crash incidences. This paper examined traffic survey analysis on major highways in Ogun State, Nigeria using manual traffic count method for estimation of traffic volume and flow pattern. The traffic data gathered were presented and analyzed using descriptive and inferential (ANOVA and Student ‘t’ test) techniques to determine variations in vehicular traffic volume and flow situation (inbound and outbound). Findings revealed that Car/SUV is the most dominant traffic relative to others. Meanwhile, ANOVA results show significant variation in traffic vo...

This article analyses survey data from 241 commercial motorcyclists in selected terminals in Ifo, Nigeria, to explore how road hazards and health risks experienced differ from one season to another. The study established that seasonality of motorcycle hazards and health risks cannot be assumed across the terminals and routes as some were dominant in either rainy or dry seasons or both. In particular, most motorcycle hazards and health risks were less likely caused by seasonal variation but by human errors and road conditions. The results underscore the importance of collecting commercial motorcyclists' perceptual data because many experience hazards and health risks that are burdensome to them.

Significantly, the purpose of urban transport is to provide both passenger and freight mobility over specific parts of urban areas including cities, and its efficiency is characterized upon transporting effectively and achieving economies of scale. Hence, this study examined intra-city mobility and characterization in Lagos, Nigeria. The data was sourced from both primary and secondary sources. Primary data detailed the use of two sets of questionnaires administered to commuters and motorists. 182 copies of questionnaire were randomly administered to commuters, while 60 units of the questionnaire were purposively and conveniently administered to motorists. Descriptive and inferential techniques were used for data analysis. Major findings revealed obvious variations in socio-economic parameters of intra-city trip makers and factors influencing trip making. It was observed that journey to work, school, shopping cum business constituted the major trips characterizing in Lagos. Findings also revealed that high patronage priority was given to most used and preferred means due to vehicle travel speed, trip purpose, and availability than safety and comfortability of modal choice. Regression analysis result revealed that commuters’ modal choice and patronage is statistically influenced by operational attributes of mode (e.g. transit time, delay duration, safety, vehicle condition and transit fare etc.) at Sig. p=0.000 and F14165 15.667 which is greater than table value at 5% significant level. The study recommended among others the formulation and implementation of effective policy for urban transport activities; standardization of service operations and expansion of infrastructural facilities including the last-mile in the city.

Without its singular significance of mobility and accessibility for farmers, agricultural produce will rot on farms, while efforts in providing food would be fruitless. This paper assessed agricultural freight transportation in Saki area of Oyo State with a view of enhancing better product delivery mechanisms for farmers. It examined farmers’ socio-demographic; nature of farming and farm characteristics; and appraised the relationship between attributes of agricultural production and freight movement. Primary data employed consists of a questionnaire designed for farmers, structured interview for government officials complemented with personal field observations of agricultural freight transportation. 225 farmers were randomly selected for questionnaire administration. Major findings revealed that food crops, vegetables, fruits and poultry products are in persistent motion in the study area and that agricultural freight is a neglected sector with significant consequences on the access to cheap and affordable urban wellbeing. Findings also revealed that agricultural freight transportation within the study is very poor and uneconomical, as this depletes farmers’ profit-making. Regression analysis results show a significant relationship between attributes of agricultural freight and transport cost (F19205 11.916= P<0.05). The study recommends extensive road rehabilitation and constructions within the study area; provision of technological driven distribution and storage infrastructural facilities; creation of a databank for agricultural freight transport; reorganization and empowerment of farmers and improvement of rural infrastructure in Oyo state and Nigeria as a whole.

Efforts to liberate the populace, most especially rural communities, from the shackles of poverty... more Efforts to liberate the populace, most especially rural communities, from the shackles of poverty, have been ongoing through several approaches since the independent era in Nigeria. The most recent is the Local Empowerment and Environmental Management Programme (LEEMP) which is tailored to undertake projects capable of alleviating poverty. This study assessed the LEEMP projects in Itesiwaju Local Government Area of Oyo State in Nigeria. Data collection methods were through a questionnaire survey and an interview. A random sampling technique was employed to sample 152 residents from the study population of 30,400 and the results were analysed using both descriptive and inferential statistics. A binary logistics regression was used to determine the influence of the LEEMP projects on the socio-economic status of residents. The findings revealed that: LEEMP projects were mostly the initiatives of both the community and LEEMP officials (72%); over 80% of the respondents observed that com...

impacts on environment and human health has increasingly attracted attentions in both
developed and developing countries. However, studies on transportation and climate
change have neglected determinants of household vehicle acquisition and use. In this study,
these factors were examined with the view to encourage the use of public transport in
Lagos, Nigeria. Stratified and purposive sampling technique were used to administer 784
questionnaire to households in 15 residential districts (high, medium and low density). Also,
within the residential districts, informal interviews were conducted in selected mechanical
workshops. Forty-nine variables from data collected were analysed using correlation and
multiple regression. Nine variables (income ICM, household-size HSZ, cost of vehicle
CSTVC, cost of trips CTRP, cost of maintenance CSMAT, distance to destination DTDS,
cost of fuelling CTFLG, years of driving experience YRDRV and frequency of trips FRTRP)
were statistically significant (P<0.05). 63.5% of variation in the determinants of acquisition
and use of household private vehicles is accounted for by 16 explanatory variables.
Household income contributed the highest (12.1%), followed by Household size (7.1%).
Cost of registration of Vehicle (CREGV) has the lowest contribution of 0.2% to the
coefficient of explanation. ICM, HSZ, DPTS, AGV, TMTV, CTRP, DTDS, YRDRV and
FRTRP have positive coefficients while CSTVC, CREGV, CSMAT, RESDN, CTSPRT, and
CTFLG have negative coefficients. Thus, the propensity to acquire and use private vehicles
by different household’s increases with increase in income, distance travel, household-size,
cost of trip, and frequency of trips.

productivity level of Apapa port in pre and post concession periods, factors responsible for
the productivity and efficiency in the port, and established difference in cargo throughput,
turn-around time and berth occupancy. Hundred (100) questionnaires were purposively
administered to Nigeria Port Authority (NPA) officials in the study area. Socio-economic
characteristics of respondents and perceptions on level of efficiency, productivity and
infrastructural development in the two periods were presented descriptively. Student‘t’ test
was used to measure difference in cargo throughput, turn-around time and berth
occupancy. Findings revealed positive changes in infrastructural development, efficiency
and productivity in post concession than pre concession periods of Apapa port. The
analyses of cargo throughput, turn-around time and berth occupancy showed significant
difference in cargo throughput (t = 2.39, P value < 0.05), turn-around time (t = 2.97, P
value < 0.05) and berth occupancy (t = 2.68, P value < 0.05) between these periods. Study
recommends proper implementation and strict adherence to existing port policies to avoid
operational delays, increase in infrastructural development like rail/road (intermodal)
connectivity which will enhance improve productivity of Apapa port and ports with similar
problems.

has resultant effect on the general wellbeing of individuals. This study examined the
housing conditions in Ajeromi Oke-Oja in Ogun State, Nigeria with the view of identifying
and assessing existing housing facilities and building construction materials; methods of
acquisition and maintenances as well as examining inhabitants’ socio-economic status on
housing conditions. Data collection methods used were questionnaire, personal
observations and informal interview. Multi-stage sampling technique was adopted to
administer 200 questionnaires among household representatives. Results were presented
using both descriptive and Chi-Square statistical methods. The findings revealed that
majority (about 70%) of the residents are low income earners with low financial capability
to access desirable houses. Findings on housing facilities indicated that 54% of toilets were
pit system and 80% of the bathrooms were traditional open roofed and enclosed systems.
For the construction materials, houses were built using mud (57%) as wall materials and
corrugated iron sheet (66%) as roof. Interestingly, about 50% houses were aged (61-99
years) and are mostly (47%) inherited structures that were poorly maintained (70%). Chi-
Square results on statistical impact of inhabitants’ socio-economic variables on housing
conditions were significantly observed. However, only income level proved a key factor
that influenced housing conditions (χ2
= 20.28, P<0.00). The study recommended that
immediate actions should be taken to avert hazards as a result of the extant housing
conditions.

system development of any society. This study identifies existing state of transport
administration and major challenges facing transport administrative structure in Lagos, Oyo
and Ogun States, Nigeria. It adopted cross-sectional research design and anchored on both
primary and secondary sources of data. Transport administrative structure (consolidation
and unbundling designs) were used to show state of transport administration operating in the
selected States, while Analysis of Variance (ANOVA) was used to prove statistical variation
among problems associated with transport administrative structure. Findings revealed that
the transport administrative structure in the selected States is not uniform as Lagos State
operates consolidation design; Ogun State follows unbundling design; while Oyo State
operates on neither consolidation nor unbundling designs. Findings further revealed that
fragmented administrative bodies with overlapping responsibilities; incomplete supervision
mechanisms; corruption and mismanagement of funds are major challenges affecting existing
transport administrative structure. ANOVA result shows significant variation among the
observed problems. Thus, study recommends that Ministry and Agencies in charge of
transport systems should run on consolidated structure that allows for easy day-to-day
planning, monitoring and coordination of various transport modes under one administrative
body.

However, the inefficiency in transportation system operations and management and the industry as a whole is not unrelated to the plethora of challenges confronting the profession and the sector as a whole. The proliferation of these challenges in Nigeria is directly linked to the weak professionalism through the activities of professional bodies and professional practice experienced in the transport and logistics sector. The quest to understand the challenges of the profession and the weaknesses of the professional bodies within the transport and logistics sector in order to proffer the best practical and policy implications necessitates the study. Given this, this study examined the involvement of expertise in the fields of transport and logistics to understand their weaknesses, the challenges facing the profession and the possible measures to strengthen the profession, as in every other profession in the built environment. This study is anchored on the concept of professionalism and professional practice and adopts a cross-sectional survey research design that relies on both qualitative and quantitative approaches to explain the opinion of professionals on the study objectives. Convenience sampling was used to administer 400 copies of a questionnaire to the professionals working in the transport-related government ministries, agencies, and parastatals found in the capital cities within the southwestern part of Nigeria. Findings reveal that the majority of the respondents are male, have between 5 and 10 years of working experience, and are registered with more than one professional body. The study also revealed that the directly concerned professional bodies in the transport and logistics sector are not the top-ranked professional bodies of the sampled professionals. Meanwhile, about 60% of the profession’s challenges ranked above the mean score, and the top-three include professional rivalry among professional bodies, the absence of functional national transport and logistics policy, and poor and low engagement of indigenous transport and logistics professionals. The top four ranked professional weaknesses are: skill gaps and incorrect placement; lack of motivation and professional rewards; low visibility and misconception of the profession; and low publicity and awareness of professional activities. Based on these backdrops, the study concludes with both proactive and reactive measures to improve professionalism in the Nigerian transport and logistics sector through the activities of the professional organisations and the profession at large.
