The purpose of this paper is to investigate the management of solid waste during monthly environmental sanitation exercise in different residential areas of Ibadan municipality, Nigeria. The study also examined how the government performed its responsibility during the exercise. This is expected to assist in improving the conduct of sanitation exercise in one of Africa’s populous indigenous settlement, Ibadan.

Collection of data for the study was through participant observation, administration of questionnaire, and interview. As a way of participating and observing, the authors were involved in the conduct of the exercise in the different residential areas of Ibadan municipality. Questionnaire was administered on respondents drawn from one of every ten buildings (10 percent) in the study area using systematic sampling technique. A respondent (preferably a household head) was surveyed from a floor of selected residential building. A total of 367 copies of questionnaire were completed and returned for analysis. Information provided in the questionnaire was analyzed using both descriptive and inferential statistics. Interview was conducted to collect information from the head of environmental sanitation unit in each of the five local government areas of Ibadan municipality.

The most widely used medium of storing solid waste was the polythene bag, which accounted for 22.8 percent of all the storage receptacles and was employed by 50.4 percent of the residents. Similarly, residents employed a combination of waste disposal methods which included burning, and dumping in the drains, river banks and on vacant plots. Methods of solid waste storage and disposal varied across the different residential areas of Ibadan municipality. It was established that despite the huge amount of money expended on the collection of solid waste during the exercise, only government-owned vans constituted less environmental health hazard.

It would assist in evaluating the success and failure of the monthly environmental sanitation exercise. It would also reveal to policy makers’ direction to which policy initiative should focus. Findings of the study could serve as a guide for the management of solid waste from similar exercises in countries of the developing world with similar socio-economic and environmental sanitation practices.

Presented in this paper are results of an investigation into solid waste management during monthly environmental sanitation exercise in Ibadan municipality, Nigeria. The study was an attempt at examining the different storage and disposal methods employed by households in the management of solid waste during the exercise. It also revealed what is committed financially into the collection and transportation of solid waste for final disposal during the exercise by government.

The benefits of interlibrary co‐operation are considered, especially in the context of developing countries. The history of library co‐operation schemes throughout the world is briefly described. The constraints on interlibrary co‐operation are also considered. A survey of academic and research libraries in the Ibadan area is reported and a possible initial co‐operation scheme outlined.

The aim of this research is to identify the factors responsible for the inability of authorities in rapidly growing megacities in developing countries to integrate disaster risk vulnerability reduction strategies effectively with their development plans.

The study followed a qualitative research strategy. A survey research approach with pre‐tested questionnaires as key data collection instrument was used in eliciting responses from 135 randomly selected built environment professionals in academics and disaster management practitioners in government and non‐governmental organizations in Lagos Megacity Area, Nigeria.

A number of factors militating against the adoption of effective disaster vulnerability reduction strategies in the area were identified. The most critical were faltering institutions and governance, weak infrastructure base and a low level of disaster education.

The sample population comprised mainly built environment professionals in academics and disaster managers across the city. Therefore, the views presented in the paper may not be considered generalizable within the context of multiplicity of stakeholders in disaster studies. However, the research presents the perception of experts and key stakeholders in disaster vulnerability reduction in the study area.

The findings can form the basis for addressing these challenges, most particularly in generating and adopting new approaches to policy formulation and implementation by the public and private sectors.

Research on this subject‐matter is very limited in Nigeria. It is, however, very relevant in efforts at addressing the challenges of sustainable development in developing countries from the human and policy dimensions.

In a developing environment, much is being done to provide for safe storage, collection and sanitary disposal of household waste; yet the problem still persists. Examines the ways in which solid waste management is undertaken in Southwest Nigeria and outlines some of the problems encountered. These include the continuous expansion of sprawling areas, funding limitations, variation in eating and waste disposal habits and laxity in enforcing sanitation laws. These and other factors make solid waste management and environmental pollution control in the area extremely complex. Suggestions are made for the recognition of socioeconomic factors in refuse depots siting and management, modification of urban planning management and a well equipped and adequately staffed Waste Disposal Agency.

Presents analytical findings of sick building situations in Sydney’s open‐plan offices. Aims to ascertain facilities managers’ perceptions of sick building impacts on discrete aspects of workspace management, with a view to raising general awareness. A total of 100 open‐plan offices in the Sydney CBD were studied, and collated data analysed using partial correlation. Significant associations were found between sick building syndrome and certain aspects. However, management control played moderating roles in some of the associations. Concludes that, with management control, sick building syndrome may be perceived as critical to only a limited workspace aspect. The implication is for sick building syndrome to be largely generalised as inconsequential to many aspects of work environment in Sydney, probably following the Hawthorne management ideology.

The purpose of this paper is to present research assessing the level of qualitative adequacy of newly constructed public housing in urban centres in Ogun State, Nigeria.

The study followed a quantitative research strategy. A survey of 517 housing units constructed through four different strategies and selected based on quota of their existence in nine public housing estates was conducted with a questionnaire as the key data collection instrument. A five‐point Likert scale was used in measuring the level of qualitative adequacy of four key housing sub‐components. The data were analysed using descriptive statistics.

Residents found the overall housing to be inadequate; they indicated that housing unit attributes were the most adequate and thus contributed most, while neighbourhood facilities were the least inadequate and contributed the least to qualitative housing adequacy.

The sample population comprised mainly house heads in public housing constructed between 2003 and 2009 therefore, the findings may not be considered to be applicable to all the public housing in the study area. However, the findings can form the basis for judging the performance of public housing in the current democratic dispensation in the study area.

The findings imply that giving adequate attention to the provision of infrastructural facilities and maintenance of existing ones can enhance the qualitative adequacy of public housing.

This paper is a pioneering effort at evaluating the qualitative adequacy of most recently constructed public housing in the study area.

The study identifies 621 authors who contributed 1,423 periodical articles and monograph publications to the geographical literature on Nigeria between 1901 and 1970. Publications/author relationship shows a perfect Bradford distribution comprising fifty‐three core authors having each six publications or more and among them contributing 38 per cent of all items. The significance of these results for retrospective bibliographical searches and their methodological implications for documentation studies in general are suggested and briefly discussed.

The purpose of this paper is to investigate the physico-chemical properties of the groundwater surrounding the Solous (solid waste dumpsite) at Isheri, Lagos, Nigeria.

In total, 40 groundwater samples were collected from ten pre-determined sampling stations. Three sample stations were established before the dumpsite; three sample stations were located in the vicinity of the dumpsite in the direction of the leachate plume, while the remaining four sample stations were situated further away and acted as a control. Sampling was carried out four times during the study period (twice each in the rainy and dry seasons). The parameters measured in situ were air and water temperatures (using mercury-in-glass bulb thermometer) and pH (using pH meter). Calcium and magnesium contents were measured using the Ca-Mg indicator; sodium content was measured using the flame emission spectrophotometry and phosphate was measured using the flame photometry. The selected heavy metals (copper, iron, lead, cadmium, zinc and manganese) were measured by using the atomic absorption spectrometer. The oxygen parameters, such as dissolved oxygen, biological oxygen demand, chemical oxygen demand and organic matter, were determined titrimetrically. The data obtained were subjected to descriptive statistics and analysis of variance (ANOVA).

The results showed that many parameters had higher values in the dry season than in the rainy season. Temperature (27.75±0.95°C), alkalinity (211.37±82.78 mg/LCaCO₃), phosphate (0.30±0.07 mg/L) and sulfate (2.78±0.35 mg/L), sodium ion (41.95±18.86 mg/L), dissolved oxygen (2.98±0.57 mg/L) and COD (33.54±4.50 mg/L) had higher mean values in the dry season than in the rainy season. On the other hand, the mean values of electrical conductivity (1,224.85±370.63), nitrate (0.01±0.003 mg/L), chloride (98.76±21.58 mg/L), calcium ion (5.38±0.68 mg/L), magnesium ion (3.05±0.05 mg/L), BOD (22.37±2.20 mg/L) and pH (6.31±0.18) were higher in the rainy season than in the dry season. The heavy metals (iron 1.10±0.05 mg/L, lead 0.12±0.07 mg/L, manganese 0.01±0.004 mg/L, copper 0.15±0.003 mg/L, zinc 0.07±0.004 mg/L and cadmium 0.02±0.02 mg/L) were fairly uniform all year round. There was also a marked decline in the values as one moved away from the dumpsite.

The implication of the findings is that human health is remarkably dependent upon safe and clean drinking water. Preserving the water resources and hindering them from pollution is preferred to the treatment of polluted water and rendering it suitable for consumption. The high electrical conductivity values obtained in the groundwater samples near the dumpsites are an indication of the effect of leachate on the groundwater quality. The high concentrations of dissolved solids in the groundwater may decrease the palatability and may cause gastro-intestinal irritation in humans, and laxative effect particularly on transits.

The pollutants from the various waste components disposed at the dumpsite percolate into the ground to pollute the groundwater. The groundwater is transported in the line of flow away from the vicinity of the dumpsite to pollute the groundwater in the area. The extent of contamination level of groundwater quality due to leachate percolation depends upon a number of factors like chemical composition of leachate, rainfall, depth and distance of the well from the dumpsite. Groundwater samples of different depths and distances from dumpsites were analyzed in the present study to understand the level of a combination.

To evaluate and examine human perception of causes, frequency, duration, impact, adjustment patterns and local attempts of control, protection and flood prediction in Niger Delta. This will enable rural dwellers to appreciate some local flood control measures.

Through questionnaires administered in reclaimed areas of urban centres and flood prone communities in the Niger Delta. The data abstracted from questionnaires were then analyzed through Kruskal‐Wallis Function. The Kruskal‐Wallis approach was used as it takes care of large data points, which consists of nominal or ordinal data.

Human perception of flooding as regards impact and local attempts at flood prediction differ among Niger Delta States. The study highlights the socio‐economic implications of flooding as regards to causes, effects, control and predictive measures.

Assist rural dwellers on cheaper local and emergency measures such as use of sand bars, opening up of creeks and assess, cleaning of drainages to allow free flow.

The paper suggests continuous enlightenment programs as a means to encourage local and emergency measures to be adopted when flooding occurs. The work is original as no such work or analysis had been carried out in the Niger Delta in the past. The paper has provided raw data and knowledge, and adds to the limited literature in the Niger Delta. On the flooding cycles of the Niger Delta. It should also raise the awareness of local dwellers on the requirements for flood emergency response and adjustment.

After almost 60 years of water supply development in Nigeria, it is unfortunate that as many as 43 per cent of the population still lack access to safe water. The situation is worse in the rural areas. There is, therefore, the need to better understand the constraints and challenges of water supply, especially in the rural areas of the country. With this regard this study seeks to assess the extent to which stakeholders are willing and able to adopt and implement sustainable, cost‐effective and environmentally friendly management options for water resources in selected rural areas of Oyo State, Nigeria.

The study areas include three rural/semi‐urban Local Government Areas (LGAs) of Oyo state. The three LGAs are Ibarapa, Afijio, and Lagelu. The choice of the three study areas is justified on the grounds that the areas are different in terms of potable water supply problems and management. The study adopted a combination of qualitative and quantitative methodology, including Focus Group Discussions (FGDs), in‐depth interviews (IDIs) with stakeholders as well as a structured and semi‐structured questionnaires survey.

The outcome of the study reveals that the knowledge base of the different stakeholder groups about the technological, socio‐economic and ecological dimensions of water resources management is very low. For some communities, however, the indigenous knowledge in the conservation of traditional water sources (e.g. streams and rivers) exists but needs to be improved.

The results formed a database on the ideas and experience of local initiatives which could be adapted to solve water supply problems in similar rural communities in Nigeria and elsewhere in the African continent.
