    Exploratory Approach to Issues and Strategy Involved in Creating Industrial Revolution Time Environmental Sustainability by Construction Firms on Sites
    (MDPI, Basel, Switzerland, 2022) Amusan, Lekan; Okalome, Chukwuemeka; Aigbavboa, Clinton
    Research outcomes all over the world have indicated that the building production sector of the construction industry relates more to the environment than other sectors of the economy and is directly involved with its sustainable activities in terms of waste generation and balancing the outcome has further been enhanced through industrial revolution time. The main aim of the study, therefore, was to carry out research on issues and challenges that revolve around contractors’ attitudes towards maintaining a controlled environment on construction sites. A mixed research design method that involved the quantitative and qualitative analysis was used for the study, while the samples were picked with a random sampling method. The total sample size of respondents is 100 questionnaires which were randomly selected for questionnaire administration to selected construction firms in Lagos state. The questionnaires were administered to professionals from dif ferent firms in Lagos State, Nigeria. A total of 100 questionnaires were distributed in this review while 92 questionnaires were duly returned by the respondents, which constitute 92% of the total questionnaires distributed. The categorical regression method was used in the analysis. ANOVA, Chi-square, and factor analysis were used for the analysis. The study discovered among other things that the following components of environmental sustainability are important to sustain on sites: environmental impact assessment, antiquities on-site, erodible surface, soil erosion monitoring, environmental ecosystem, and environmental biomass, rock mass found on-site, soil contamination monitoring and ecosystem services valuation, soil salinity monitoring, and water resources conserva tion. The study concludes by recommending that the design of an effective way of disposing of waste on-site and continually improving construction methods and procedures to enhance performance in achieving a sustainable environment are vital to sustaining a viable construction environment among other factors.

    Three attributes determining land values in three selected housing estates in Uyo, Nigeria
    (Frontiers in Sustainable Cities, 2024) Iroham, Chukwuemeka O.; Okagbue, Hilary I.; Ekanem, Inimfon F.; Peter, N. J.; Samuel, Olugbemisola W.; Nto, Sunday E.; Isiaka, Saheed; Adedotun, Adedayo F.
    There is a knowledge gap regarding the specific attributes (location-specific, environmental, and neighborhood) that impact land value, the relationship among these attributes, and the degree of impact on the land values in residential estates in Uyo, Nigeria. The three factors all combine to create a unique picture of a place, impacting its desirability and ultimately, its land value. This study explores the relationship between various land value attributes within specific residential estates (Ewet Housing Estate, Shelter Afrique Estate, and Akwa-Ima Estate) in Uyo. A questionnaire was designed and used to solicit data from the respondents living in the three estates with the aid of the purposive sampling technique. The findings revealed the following: Closeness to school is the location-specific attribute that contributes the most to land value, and closeness to recreational centers contributes the least. The presence of security and police stations had the most significant contribution to land value, and the presence of noise in the neighborhood had the least significant contribution. Peace, quiet, and beauty had the most significant contribution to land value, and the presence of lakes and water bodies in the environment contributed the least to land value. The factor analysis yielded two major factors for location-specific attributes: ‘transport’ and ‘place’. The factor analysis grouped the neighborhood attributes into two factors: ‘easily controlled’ and ‘not easily controlled’. All three attributes of land values are positively correlated with one another. Implications for research and recommendations were made.
