During oil and gas exploration, sustainability is critical to the industry, due to the generation of wastes, possible environmental contamination and release of gaseous emissions such as carbon dioxide. Diverse wastes generated during the process include drilling muds, produced water, drill cuttings and other constituents that can impact the environment and the communities around such operations. Nevertheless, advancements in oil and gas drilling techniques minimise environmental impacts, thus driving sustainability and strategies that can effectively reduce waste generation, pollution and gaseous emissions. This study investigates environmental management and control during petroleum exploration. The study adopts a qualitative approach through review of literatures, to study the issues during petroleum exploration. The major findings reveal the rapid improvement companies are taking to account for their activities that can interfere with the environment. In conclusion, whilst oil and gas revenues continue to foster social and developmental opportunities, hazards and controls must be established to effectively structure environmental compliance with best practices.

Health and safety can never be talked down in all spheres of life, particularly the construction industry. The construction industry is one of the other major industries in the world whose activities are ever-increasing and becoming more complex every passing of each day. The construction industry plays a pivotal role in the GDP of its host nation and, in some cases, other affiliated countries. The significance of health and safety, more specifically in the construction industry, informed this study’s necessity. Therefore, this study aims to assess the health and safety performance measurement through organisational culture in construction sites of Katsina Metropolis, Nigeria. Katsina metropolis is preferred for this study because it is the capital city of Katsina state; hence, major construction activities are done there. For the data collection, a self-administered structured questionnaire was used. This is because it offers a high rate response advantage. The collected data were analysed using the statistical package for social science (SPSS) version 22 because of its general acceptability of results and ease of use. The study adopted a quantitative approach, and data were collected through a questionnaire survey, and the respondents were the architects, quantity surveyors, civil engineers and builders who were randomly selected. Two hundred fifty structured questionnaires were self-administered to the professionals. The study adopted a proportionate and simple random sampling technique, and SPS software version 22 was used for data analysis. The results of this study show that the level of management commitment and involvement in health and safety is highest in the head office. The result revealed that the level of worker empowerment is highest on the workers kept informed of provisions of the Health &Safety plan, workers helping in developing Health &Safety rules and workers involved in Health &Safety inspections. The least level of worker empowerment is based on workers’ involvement in Health & Safetyfeedback forums, workers’ participation in Health & Safetyrisk assessments and Health & Safetyinspections used as training tools for workers. The study recommended that the health and safety of the workers should be improved by the construction projects head office actively monitoring the Health & Safety performance of the projects and workers, head office rewarding workers who make an extra effort to do work in a safe manner and head office ensuring that the Health & Safety equipment is bought. The study recommended that the construction industry emphasise worker empowerment through workers’ involvement in Health & Safety feedback forums, workers’ participation in Health & Safety risk assessments and H&S inspections used as worker training tools. This will lead to improving construction project workers’ empowerment. It is recommended that the workers’ training should be given more attention through the workers’ induction before work, training workers in the proper use of equipment and provision of correct tools and equipment to execute construction work.

ENVIRONMENTAL RISK AND SAFETY NATURE GAS SHIP DESIGN AND OPERATION
PROF DR OLADOKUN SULAIMAN OLANREWAJU
The quest for an efficient fuel-friendly environment has been recognized in the maritime industry for a long time through improvements in gasoline and diesel by chemical reformulation. Inconvenience posed by these reformulation chemicals is performance problems; cold-start ability, smooth operation, and avoidance of vapor lock. The climate change problem has further aggravated the need to use fuel that could contribute to a decrease in greenhouse gases and ozone-forming pollutants. Alternative fuels to petroleum have been identified to include, compressed natural gas (CNG); liquefied petroleum gas (LPG); methanol from natural gas LNG. Selection of this towards centralized reduction of Green House Gases (GHGs) will depend on ease of use, performance, and cost. LNG cargo is conditioned for long-distance transfer while CNG and LPG cargo are conditioned for end user consumption and short-distance transfer. It is, therefore, clear that promoting the use of CNG will catalyze boosting of the economy of coastal shipbuilding and transportation, including environmentally friendly utility fuel, and new generation of intermodal transportation and supply chain. Since the danger behind the use of this gas could not be either underestimated by coastal operation proximity and consequence. The paper will discuss risk and potential regulation that will formulate beyond compliance, and decisions towards the use of top-down risk-based design and operations that will reinforce new integrative, efficient, environmentally friendly, reliable multimodal and intermodal links advanced concepts for LPG ship operating in coastal and restricted waters.

The study aimed at assessing structural, Neighborhood quality and locational factors influencing rental values of commercial properties. A survey research was carried out through the use of questionnaire instrument. A total of three hundred and fifty (350) questionnaire were administered, out of which three hundred and four (304) were retrieved. The simple random sampling technique was adopted for the study, while data obtained from the field were analyzed using statistical packages for social sciences. The study also found out that, commercial property values in the study area were highly influence by locational factors such as access to the central business district, access to railway stations, access to bus stops, access to health facilities etc. The study concluded that all the structural, neighborhood and locational determinants or factors influenced commercial property values in the study area. It is recommended that prospective property developers should take cognizance of locational, structural and neighborhood factors that significantly affect property value in the study area as this would help the marketability and viability of the commercial properties investment. The study recommends that the federal government should take appropriate steps to cushion the effect of economic recession or meltdown when it arises. This is to reduce its devastating impact on the rental growth of commercial properties.

This study has filled a gap in knowledge as it was channeled to analyses of change in land cover on tree species which previous scholars does not address comprehensively. This was done to have update information on the land cover and how it affects tree species composition and diversity and then apply the report for sustainable planning of future land use in the study area. This study adopted a survey research design and was designed in a way that data were collected using GIS and field survey. Data were sourced from primary and secondary sources and were both quantitative and qualitative data. The study concluded that change in land cover mainly from growth of built-ups is a big factor in biodiversity loss especially tree species. Result shows that built-up land is increasing rapidly while forest land is reducing drastically. The following recommendations were made in line with the findings of this study: Green Infrastructure (GI) development should be adopted in the area to reduce the effects of the advancing built-up in the study area. The approach should include creation of green space where native tree species can be maintained within the built-up areas. The State and Local Governments can foster the adoption of GI through public enlightenment, training, and incentives. More efforts should be put in place by all stakeholders to conserve the diverse species of trees being threatened by land cover change.

Environmental experts have posited that environmental sustainability largely depend on the citizens participation in efforts towards environmental control. This paper aim to analyse citizens participation in environmental control programmes, with key objective to identify factors affecting citizens participation in the study area. The study area comprises ten oil and gas bearing communities within the Nun River Oilfield in Bayelsa State. The study utilised mainly primary source of data collected through the survey method; a well structured questionnaire was administered on 390 respondents in all sampled communities selected through the simple random sampling technique. Data were both descriptively and statistically analysed. The results of the descriptive analyses showed low participation between communities. Similarly, results of an ANOVA test showed that F-ratio calculated 1527.552 was greater than tabulated value of 3.84, and P-value 0.000 was less than significant 0.05 suggesting low participation in environmental control significantly varied among individuals and communities. Results also showed significant relationship with socioeconomic characteristics: income and educational attainment and participation. 77℅ of respondents were unaware of relevant environmental laws and the consequences of their harmful anthropogenic activities, while 20% stated been aware, but blamed income level, illiteracy and nature of subsistence occupation for engaging in such activities. Results also showed that 80% of respondents were willing to participate in environmental control programmes. Hence, it is recommended that Government at all levels should should seek citizens and stakeholders involvement in the formulation and implementation regimes of environmental control programmes, and organise awareness or enlightenment programmes to educate the citizens on the need to strike a balance between socioeconomic development and environmental sustainability.

Department of Technical Education, Shehu Shagari College of Education, Sokoto.
This research delves into the critical aspects of construction and demolition waste (CDW) management in Nigeria, shedding light on historical recycling practices and emphasizing the escalating challenges faced by the construction industry. With CDW constituting a significant portion of Nigeria’s waste stream, improper disposal methods, such as illegal dumping and landfills, pose environmental and economic threats. Drawing on insights from global waste policies, the study highlights the need for robust regulatory frameworks and effective waste management systems. The research employs a qualitative approach, relying on extensive data collected from secondary sources, including journals, books, newspapers, magazines, archives, and online platforms. Through content analysis, the study aims to extract meaningful insights and patterns, providing a comprehensive understanding of CDW management practices in Nigeria. Assessment of current CDW practices reveals challenges such as substantial waste generation, landfill dependence, lack of recycling infrastructure, and unregulated informal waste management. In contrast, the benefits of CDW recycling and reuse encompass reduced waste disposal costs, job creation, increased revenue, and economic competitiveness. The study proposes strategic recommendations for advancing sustainable CDW management in Nigeria, emphasizing policy development, investment in recycling infrastructure, public awareness, collaboration with the informal sector, and research and innovation. Implementing these recommendations requires coordinated efforts from government bodies, the private sector, and the community to establish a more sustainable and responsible approach to CDW management in Nigeria.

The issues of adequate implementation of construction Health and safety (H & S) good practice during project tendering and execution stages has not attracted needed attention by the quantity surveyors (QS). This study assessed the roles and responsibilities of Quantity Surveyors (QS) towards ensuring health and safety management at construction sites in Nigeria. A structured questionnaire was used to
collect information from various respondents who were professional registered QS within the North – Central Nigeria. The survey was conducted using random sampling techniques were used to select one hundred and twenty (120) respondents out of which (80) of them were suitable for analysis, which represent a potential responses rate of sixty-seven percent (67%) of the total. The data were analyzed using simple percentile and mean item score. In addition, an in-depth interview amongst six- selected Registered Member Nigerian Institute of Quantity Surveyors. The interviews assisted the researcher to gain more insights of respondents’ perceptions, and to validate the questionnaire results. The study findings suggested that the Quantity Surveyors non-inclusion of H&S section in the BoQ has undermine serious H&S practice in construction. In addition, the QS’s lack the earnest commitment and leadership inputs to foster financial provision for H&S items in the bill of quantities. The study further revealed that QS play little or no significant role to advice or select the contractors with H&S competencies during tendering stage. Thus, if the QS would play active leadership responsibility in integrating of H&S cost items in bill of quantities it will significantly promote construction H&S good practice in Nigerian construction sites.

It is common that certain architecture is identified with certain group of people either as a state or as a nation as such the Hausa ethnic group is not an exception with an explicit idea and housing arrangement that provide shelter, security and comfort. The religion practiced largely is Islam, mainly from the Fulani and Hausa ethnic groups forming a large group of mixed blood and various physical types, linked by languages, religion, and a common way of life leading to the present prototype Hausa traditional housing forms applied mostly to eighty percent of Hausa speaking state by which katsina is not an exception. A good architecture must satisfy a trinity of requirements in a user in order to depict the language the society understands i.e. social and cultural factor, religious, and environmental factors. These trinities make the house to have a conducive atmosphere for living because it provides physical need, emotional needs in terms of aesthetics and psychological stratification and also the intellectual needs in areas like reasoning, uniformity and perfection. The categorization of Hausa traditional architecture is rooted into two groups namely the determinant factors (culture and climate), and moderating factors (history, effect of colonialism and building material). The determinant housing forms and structure in terms of social structure and spatial organization starts the existence of the family, family growth and expansion and disbanding forming the nuclear family, the composite family and the collateral agnate family. While the spatial growth circle involves the entrances and courtyards of the house. Tsakargida which is provided as women quarters arranged around a courtyard which fulfil the religion and cultural injunction on women in purdah are secluded from the outer male reception area (zaure).
