Until recently, Port Harcourt was known as the “garden city of Nigeria” because of its neatness and the overwhelming presence of vegetation and flowers all over the metropolis. But today, the presence of piles of refuse dotting the entire city may have turned Port Harcourt rather to a “garbage city”. Indiscriminate dumping of wastes – industrial, commercial and household – such as food waste, paper, polyethene, textiles, scrap metals, glasses, wood, plastic, etc. at street corners and gutters, is still very common. The situation is so bad that traffic flow is obstructed, while there is likelihood that leachates from such dumps, after mixing with rain water, have the potential to contaminate drinking water. The basic solid waste management processes of collection, transport, segregation and final disposal appear to be very inefficient. This research carefully assessed the present system of solid waste management in Port Harcourt, with the aim of identifying the main bottlenecks to its efficiency and the way forward. The subject matter of solid waste management is the main object of discussion throughout this article.

The purpose of this paper is to highlight the relationship between lifestyles, household and household wastes, by exploring possible future development path for the lifestyle and the possible consequences for household waste composition. The study predicates on a reasonably simple and straightforward idea that the waste generated from homes is a product of the way the people live and since the way of life of people change overtime, getting an idea of how people may live in future may give an insight into the sorts of composition of waste produced by them. It tends to provide a contribution to the evidence base on household waste at a general level.

The overall approach hinged on the notion that the household is the appropriate analytical unit of household waste production composition. This specified inputs needed to develop scenarios for future waste composition. The weekly generation of sorted wastes from their various sources was determined by direct measurement in kilograms on a weighing scale. Questionnaires were administered to elicit information on key drivers and factors that influence lifestyles scenarios and their development. Interviews were conducted with relevant stakeholders and government agencies on waste management.

The results indicated that food related waste constituted the major percentages and tonnages (44 percent, 269,870 tons) of household waste, while the least portion was glass (1.2 percent,7,278 tons). The key drivers responsible for generation of food waste include level of income, subsistence farming that generate organic food waste and rise in fast food outfits that give preference to readymade food over cooking at homes. The drivers for developing future scenarios include population, government regulations, nature of apartment, level of income, consumer spending, management technology. Three scenarios were developed: status quo trends, strong government and destination point.

Models should be developed for better simulation studies of lifestyle scenarios by quantifying household wastes in terms of carbon footprint and money instead of relying on quantities generated in tons. Further studies should extend to other sources of waste such as industrial waste, electrical and electronic waste, among others. The implication from research findings shows the need for sustained for sustained awareness on people’s lifestyle with regard to handling of household wastes by government agencies, institutions and non-governmental organizations. Scenario planning is required to enable, encourage and engage householders to make changes in their lifestyles.

Food waste, by virtue of its tonnage and percentage composition, dominated the overall picture during the study period and will continue to do so in the near future. The composition of household waste in the future will be driven by the population and lifestyles of the householders. The drivers of lifestyles are crucial factors that determine the picture of the future. Furthermore, it is possible to conjecture circumstances in which household waste is converted to wealth at the destination point but the period before then imply some radical changes in both lifestyles and underlying economic growth facilitated by a strong political will.

This research could be of enormous benefit to policy makers, practitioners and others with an interest in or responsibility to the development and implementation of sustainable waste management. Scenarios are devices for enabling organizations and the individuals within them better to understand their operating environment, so as to make better decisions. This research is a scenario-planning exercise, considering how future changes in lifestyles of people in Port Harcourt metropolis now and in future may impact on the future composition of wastes they generate.

The purpose of this paper is to examine the impact of rapid population growth due to uncontrolled and unplanned urbanization as it affects environmental degradation through solid waste generation in Port Harcourt Metropolis, which has brought about the problem of solid waste management to city authorities and state government

The study involved the administration of questionnaires to 76 different households with a total population of 393 persons giving an average size of 7 persons per household. Also, formal interviews with officials of relevant government departments as wells as private stakeholders in urban solid waste management were conducted. The questionnaires were designed to elicit information on the characteristics of the respondents and waste generation capacity as well as disposal methods. The data abstracted from the questionnaires were analysed using the multiple linear regression to test for the significant differences. The study period was between January 1999 to December 1999

A total of 207.3 tonnes of solid waste was generated giving per capita annual waste generation rate of 0.53 tonnes equivalent to a waste generator rate of 1.45 kg of waste per capita daily. Analysis of solid waste composition was by land use types. The study showed that cartoons accounted for 16.1 percent, while papers and food remnants had 14.4 percent and 26.6 percent of total waste generated respectively.

Assist city dwellers tackle the problem posed by urban waste through provision of adequate infrastructure and social services.

The paper suggests continuous enlightenment programmes as well as employment of good technical services in the management of solid waste rather than the use of political will to tackle the problems. This work is original, as no such analysis has been carried out in Port Harcourt metropolis. The paper has provided data and knowledge upon which further research can be carried out.

The purpose of this paper was to investigate the physicochemical attributes of the Ogu Creek serving the Onne Ports in Port Harcourt, which is impacted by ports transport activities, for establishment of its pollution status.

In situ measurements were made at six sampling points for water temperature, pH, salinity, dissolved oxygen (DO), turbidity, and conductivity with HORIBA U‐10 Water Quality Checker and for total dissolved solids (TDS) with HACH conductivity/TDS meter. Other parameters were determined using standard methods. The principal components analysis (PCA), test of homogeneity in mean variance and Pearson correlation were used to analyze data.

The lower range of pH (5.28), the upper ranges of Al (1.20 mg/L) and Fe (3.25 mg/L), as well as the concentrations of Cd (0.022±0.011 mg/L) and Cu (0.08±0.01 mg/L) were outside the Federal Ministry of Environment's permissible limits for aquatic life. Four PCs, which were most correlated with essential pollution indicator physicochemical parameters and ions formed the extraction solution that contributed a cumulative 95.258 per cent variability in the original 22 parameters. Of the associated shipping activities, garbage generation on board accounted for the highest waste volume (97.13 per cent) and bilging impacted hardness (r=0.992) at p<0.01, bunkering impacted Pb ion concentrations (r=0.948), accidental dumping of effluents impacted water temperature (r=0.881), and fish trawling and deliberate dumping of effluents each impacted DO (r=0.896 and 0.957, respectively) of water column at p<0.05.

Bilging, bunkering, dumping of effluents and fish trawling activities constituted pollution in the waterway.

All data relating the physicochemical parameters of the waterway were generated from laboratory analyses by the authors.

This column takes us to the University Port Harcourt in Nigeria to learn about the new Information and Communication Technology Centre.

Background of a how an Information and Communication Technology Centre evolved at a Nigerian University including the extent from development staging to final implementation.

Very realistic experience and that combined extensive planning and patience, with long term goal setting. Seeing how libraries absorb additional information technology responsibilities and how the staff works through all the transitions is a good case study approach to management and service economies.

For libraries in developing countries this is a good introduction to how to define a very practical need and see it evolve to fruition within the organizational and institutional parameters.

This paper aims to quantitively assess the resilience of residential properties to urban flooding in Port Harcourt, Nigeria, and assess whether they vary at spatially aggregated scales relative to the level of flood exposure.

The study synthesizes theoretical constructs/indicators for quantifying property level resilience, as a basis for measuring resilience. Using a two-stage purposive/stratified randomized sampling approach, 407 questionnaires were sent out to residents of 25 flood-prone areas, to solicit information on the resilience constructs as indicated by the adaptation behaviors of individual households and their property attributes. A principal component analysis approach is used as a mechanism for weighting the indicators, based on which aggregated spatial-scale resilience indices were computed for the 25 sampled areas relative to their levels of flood exposure.

Area 11 located in the moderate flood zone has the lowest resilience index, while Area 20 located in the high flood zone has the highest resilience index. The resilience indices for the low, moderate and high flood zone show only minimal and statistically insignificant differences indicating maladaptation even with incremental levels of flood exposure.

The approach to resilience measurement exemplifies a reproducible lens through which the concept of “living with floods” can be holistically assessed at the property level while highlighting the nexus of the social and technical dimensions.

The study moves beyond theoretical conceptualization, to empirically quantify the complex concept of property-level flood resilience.

The University of Port Harcourt Library initiated a scheme whereby young students with a variety of subject backgrounds would be recruited and trained to act as an effective link between library resources and the faculty. Discusses the beneficial effect this unique plan has had in all aspects of library services, and the impact it has made on the library users by having librarians with specialist backgrounds able to offer many and varied subject data knowledge when required by university library users.

Identifies and assesses the key determinants of service quality and determines the quality of service offered by two ports in Nigeria using the SERVQUAL model. The main service attributes that are important to port users are determined. Relevant literature is reviewed to give relevance to the survey. Data for the study was collected via a well‐structured questionnaire, analysed, and perception‐expectation gap scores evaluated. Reveals that the service offered at Port Harcourt had a favorable influence on actual perceptions of quality of service and that there is improved service at the port in comparison with Lagos. Reveals that port managers focus on those dimensions which receive lowest ratings and attributes with high gap scores. This is a single‐industry (port) survey, thus raising doubts about the generalizability of the results. Reveals that port managers should be looking carefully at each of the dimensions where customers perceive receiving a different service than expected. Managers should also be in regular contact with employees in order to assess their service experiences. Shows how using SERVQUAL to identify important attributes of port service quality could be used as an early warning system for ports, thus being an important tool for managers.

The purpose of this paper is to show impacts of household wastes handling on some physicochemical parameters of surface water, soil, sediments and borehole water samples in Port Harcourt. Waste generated from the households are indiscriminately dumped on roads, stream channels, bush lands and open spaces thus defacing the landscape of the city, flooding and spreading vector-borne diseases. As a result there is unsustainable and wasteful utilisation of resources which gives rise to pollution of the environment. The research determines the pollution profile of some dumpsites, surface water bodies that act as recipients of household waste from result of analysis of physicochemical parameters.

Major dumpsites in the city were selected for sampling. Three sampling stations at upstream, discharge point and downstream were selected for water and sediments. Water samples were collected in one-litre plastic containers, and then labelled and transported to laboratory for analysis. Sediment samples were collected at a depth of 5-10 m under water and preservation, handling and analysis were based on standard principles and procedures. Soil samples were dug with auger at both top (0-15 cm) and bottom (15-30 cm) in radial coordinates. The soil and sediment samples were first digested using the wet oxidation method before analysis with atomic absorption spectrophotometry.

The physicochemical analysis of surface water samples showed that conductivity, salinity, turbidity, sulphate, phosphate, magnesium, total hardness and lead exceeded the World Health Organization and Nigerian Industrial Standard limits for drinking water qualities at the sampled areas. The same parameters in addition to pH and manganese also exceeded the limits for sediment samples. The soil pH showed acidity at the sampling stations for both top and bottom depths. Conductivity, sulphate, iron, manganese, phosphate and lead also exceeded the FMEnv Guidelines and standards for soil quality. The continuous discharge of household wastes on water and soil resulted in elevated levels of some measured parameters.

The research was limited by funds. The cost of sampling and analysis was enormous and limited the study to parameters that available funds could carry. This factor also stretched the period of study. The non-availability of sponsorship made it difficult to extend the research to soil particle size distribution and the underground water movement of the study areas. Another limitation was logistics as the study covered vast areas of the metropolis demanding steady means of mobility that was not available. Epileptic supply of power delayed the timely delivery of result of analysis.

The results of the analysed physicochemical parameters of water, sediments, soil and borehole water samples indicated spatial variations in their values at the study area, with higher values at the discharge points and downstream than the upstream, while for the borehole water analysis, the effect was more pronounced at stations with appreciable quantity of degradable household wastes. The levels of some physicochemical variables exceeded standard limits as a result of continuous discharge of household wastes .The implication is that household waste handling influenced the physicochemical variables negatively and constant monitoring serves as a useful tool of abatement.

This work is original and has not been published before in any book or journal article locally or internationally. The research related waste handling lifestyles with concentrations of measurable parameters, which is an additional work to what other authors have done. The value is that data generated will be a reference material to other researchers, city planners, government agencies and institutions that are involved with environmental management. Furthermore it has added a new dimension to the discipline of waste management in terms of scope and contribution to knowledge.

The T-O-E framework enjoys robust scholarly accolade but it rarely espouses clearly task and individual factors. Although task and individual contexts had been separately addressed by task-technology-fit (TTF) and unified theory of acceptance and use of technology (UTAUT), respectively, the purpose of this paper is to complement and/or extend the T-O-E’s insights by integrating TTF and UTAUT frameworks, and developing and empirically testing a 12-factor framework that spans five contexts.

Survey data were proportionally collected from six groups of small service enterprises with strong operations in Port Harcourt, Nigeria and the mode of sampling was purposive and snow-ball while analysis involved logistic likelihood regression.

The relationship between adoption and the factors within the contexts of technology, organization, environment and task were statistically supported though some had negative coefficients. For individual context, social factor had a statistically significant negative coefficient but hedonistic drive was not statistically supported.

The study is limited by its scope of coverage; therefore, extended data are needed to apply the findings to other sectors/industries and to factor in the implementation and post-adoption phases and business-to-business adoption in order to forge a more integrated and holistic adoption framework.

The findings encourage vendors and policy makers to place more premiums on organizational and task factors than on technological, environmental and individual factors and to craft informed marketing programs that would appeal to actual and potential adopters and cause them to progress in the loyalty ladder.

This paper contributes to the growing research on technology adoption; it uses factors within the T-O-E, TTF and UTAUT frameworks to explain adoption of technologies and to establish the underlying relationships amongst T-O-E factors through integrating other useful frameworks.
