ABSTRACT

Abuja, a planned city conceived in 1976 was largely developed in four phases to accommodate 36 urban and 5 suburban districts. However, the corresponding development of satellite towns within the FCT and the neighbouring states of Nasarawa Kaduna, Kogi and Niger has been haphazard in nature. This is largely due to the rapid urban migration from the largely rural heartland of Nigeria. The emergence of slums is the antithesis of sustainable cities. Indeed, slums are the emerging human settlement of the 21^st century and unfortunately, they are here to stay According to UN HABITAT, by 2007, 50% of the human population live in cities, with an estimated 75% by the year 2030. Of this urban populace, one-third of the population are slum dwellers. Slums develop largely due to changing dynamics of the urban economics. Ill-defined and conceived government policies also contribute to the urban blight which results in slum development. This paper used a case study methodology to examine the issues of slum development in the satellite development in Nyanya, Abuja. This research instrument enabled the study shed light on the unique characteristics of slum settlements based on the findings. Two principle data types, spatial and attributes were considered, drawn from primary and secondary sources. The findings highlight the factors that attract slum dwellers to slum settlements, which hinder sustainability development of Abuja as a city. This study also gives pointers to sustainability in city development and is relevant in itemizing factors which are critical in determining strategies that can be used by stakeholders in the design and construction of the built environment of cities.

ABSTRACT

This study examined the nature of mining operations, the extent of environmental degradation caused by mining activities and the effect of mining on other human activities. Data was sourced using observation, focus group discussion and direct measurements of the diameter and depth of thirty (30) pits from the three mining locations in Fika Local Government Area. The data was analysed using descriptive statistics and showed average pit diameter and depth for Gashuwa is M±SD (1.16 ± 0.05) and (8.8 ± 3.25), Garin Ari has M±SD (1.16 ± 0.05) and (11.40 ± 3.77) while that of Turmi is M±SD (1.16 ± 0.06) and (12.90 ± 3.60). Ubiquitous mine pits and mounds of overburden dumps are the basic indicators of landscape degradation at all the mine sites. Soil erosion and land subsidence observed. Mining activities have also encroached upon other land use activities such as crop cultivation, grazing and forestry. The environmental impact of gypsum mining can be mitigated through increased level of awareness of environmental hazards among inhabitants; provision of tarred road to stop encroachment on agricultural land by heavy trucks and Government should enforce existing regulation on reclamation of mine site.

ABSTRACT

The study on the impact of chemical waste materials from dump sites of Federal College of Education (F.C.E) Zaria is an investigative study. The study samples abound in the geographical areas of F.C.E Zaria. They include the six dump sites, the characterization of their compositions form the thrust of this work. The data gathered were centrally inferential and were from primary sources. Close survey of the areas were carried out in other to observe and measure the nature and types of waste generated in each dump site. The use of inferential statistical techniques was used in the course of analyzing the data. Dump site B is the largest and poses serious health hazards to the School of Education and School of languages i.e. both staff and students of these schools are more prone to diseases like cholera, malaria, lungs cancer e.t.c. The study finally concluded by recommending among several others, the immediate removal of dump site B and immediate mitigating measures to forestall any emergency of possible health problems.

ABSTRACT

Emergency management is the consequence of natural and man-made disaster, to which collapse disaster has started gaining awareness in Nigeria. Building collapse response needs rapid decisions within a short duration, the initial response being an obligation for all; government, individual, Non-governmental agencies, professional organisations and Nigeria communities at large. The paper examines the prevalence of collapse building – disaster, preparedness, response and sustainable reconstruction. It discussed this in the framework of architectural and planning modus operandi. The main objective of this paper is to examine roles of stakeholders particularly the architects as they assist to find lasting solution towards combating the upsurge trend of collapse structures in Southwest Nigeria, while contributing through architectural planning, design and construction development strategies to help mitigate rate of building collapse. Since, building collapse is now becoming prominent form of disaster on its own. The paper takes into consideration design and construction stages of building in course of search for the problem, while it integrate areas of architectural spatial design techniques aimed at mitigating effect of collapses on infrastructures. To achieve the aim of this study, which is to examine roles of stakeholders particularly the architects in collapse building with a view to proffering solution to identified causes. In order to achieve the objectives of the research secondary data were gathered for the study and are obtained from dailies, reports and other similar research documents that records causalities.

ABSTRACT

The traditional methods used to measure project success in the construction industry are ‘the iron triangle´ of time, cost and quality. These criteria are no longer sufficient as other factors related to project sustainability are being demanded. Sustainable procurement policies require that projects provide social and economic gains to host communities. Construction works procured using public private partnership arrangement (PPPs) are more risk prone than those procured using other forms, primarily due to the lengthy concession period and the multi-parties involved in the arrangement. In Nigeria, researches on the assessment of the performance of projects procured using PPP are few due to the novelty of the approach. Many projects are still at pre-construction and construction stages whilst few are at the operation stage. It is important for the public and private sectors to establish effective risk allocation strategies for public-private partnership (PPP) projects in order to achieve a more efficient process of contract negotiation and reduce the occurrence of dispute during the concession period.Developing countries like Nigeria are in need of infrastructure development and some countries are attempting Public Private Partnerships (PPPs). In Nigeria for example, the Federal government has been trying to find ways of implementing projects funded through PPP arrangements. PPPs are risk sharing investments in the provision of public goods and services, seen by governments as a means to promote investment platforms, which would not have been possible within the available public-sector budget, within reasonable time. However, there is no in-depth analysis of the critical factors that are likely to affect the success of PPP projects in developing countries. The objective of this paper is to address the aforementioned gap and contribute to the knowledge base of success factors for PPP projects in developing countries using Nigeria as a case study. Success factors were identified from literature survey and validated using interviews with the major stakeholders in the construction industry i.e. the contractors representing the private sector, the financial institutions and government departments largely charged with construction of facilities. The various factors were rated using questionnaire surveys. The factors were then ranked using the Coefficient of Variation on the importance of the factors for each of the parties involved. Competitive procurement process, well organized private sector, availability of competent personnel on PPP projects implementation, and good governance are the most important factors identified.
