Some Aspects of Soil Thermal Properties (Published)

Globally buildings are responsible for approximately 40% of the total world annual energy consumption. Most of this energy is for the provision of lighting, heating, cooling and air conditioning. An increase in awareness of the environmental impact of CO2, NOx and CFCs emissions triggered a renewed interest in environmentally friendly cooling and heating technologies. Under the 1997 Montreal Protocol, governments agreed to phase out chemicals used as refrigerants that have the potential to destroy stratospheric ozone. It was therefore considered desirable to reduce energy consumption in order to decrease the rate of depletion of world energy reserves as well as the pollution to the environment. One way of reducing building energy consumption is to design buildings, which are more efficient in their use of energy for heating, lighting, cooling and ventilation. Passive measures, particularly natural or hybrid ventilation rather than air-conditioning, can dramatically reduce primary energy consumption. Therefore, promoting innovative renewable energy applications including the ground source energy may contribute to preservation of the ecosystem by reducing emissions at local and global levels. This will also contribute to the amelioration of environmental conditions by replacing conventional fuels with renewable energies that produce no air pollution or the greenhouse gases (GHGs). An approach is needed to integrate renewable energies in a way to achieve high building performance standards. However, because renewable energy sources are stochastic and geographically diffuse, their ability to match demand is determined by the adoption of one of the following two approaches: the utilisation of a capture area greater than that occupied by the community to be supplied, or the reduction of the community’s energy demands to a level commensurate with the locally available renewable resources. Ground source heat pump (GSHP) systems (also referred to as geothermal heat pump systems, earth-energy systems and GeoExchange systems) have received considerable attention in recent decades as an alternative energy source for residential and commercial space heating and cooling applications. The GSHP applications are one of three categories of geothermal energy resources as defined by ASHRAE and include high-temperature (>150°C) for electric power production, intermediate temperature (<150°C) for direct-use applications and GSHP applications (generally (<32°C). The GSHP applications are distinguished from the others by the fact that they operate at relatively low temperatures.

Investigation into the Acquisition and Development of Wetlands in Built Environment Industry: A Case Study in Kumasi Metropolis (Published)

Wetlands are the most important ecosystem of the earth the depletion of ecosystems turn to weaken their ability to provide essential services. This study investigates into the trend acquisition and development of wetland in Kumasi metropolis. The study adopted a cross-sectional survey design with a mixed method approach. 120 respondents from 10 wetland sites were randomly selected from a population of 450 developers for the study. The research used questionnaire to collect data. SPSS and Smart PLS were used to analyse the data collected. The study reveals that, the state of wetlands before they were taken over by construction activities were the presence of natural vegetation, plant and animal species. The study established that the major reason for the development of wetlands is it closeness to social amenities and the main allocator of wetlands are chiefs. Moreover, there is an increasing trend in the acquisition and development of wetlands in Kumasi. Finally the study reveals that the major factor influencing wetland acquisition and development in Kumasi were prime location of wetlands. It is recommends that there should be effectual collaboration between city authorities and traditional land owners in implementing the planned layout of the city.

Construction Externalities: A Theoretical Insightand the Nigerian Scenario (Published)

Very little is known about the subject of construction externalities, especially amongst stakeholders in the Nigerian construction industry and built environment, yet its existence and effects are palpable. Hence, the study, via relevant literature and personal observations sought to provide; first, a theoretical understanding of the nature of construction externalities; its constituents or composition as well as its effects, and secondly, to point out the level of awareness on the part of stakeholders and the manner or extent to which they have been addressed or considered in Nigeria. Ultimately, this paper presents as a solution to efficient and balanced allocation of resources, realistic taxation and better economic planning by the Nigerian government; the need to be apprised of the benefits and adverse effects of construction externalities on the citizenry.

TOWARDS A BETTER UNDERSTANDING OF THE CONCEPT “MAN AND HIS ENVIRONMENT” THROUGH AN “INTEGRATED ENVIRONMENT” APPROACH (Published)

“Man and His Environment,” is a topical issue in all discussions on the environment, which itself has been recognized as an important issue in sustainable development. A companion paper to this one on the title “Religion, Man and His Environment” (Fatubarin and Alokan, 2013), discussed the interactions of man with the natural environment. However, in order to have a near comprehensive account of the concept of man in his environment, all the environments, natural, socio-economic, political/governmental, built and spiritual, are considered as components of an integrated environment, in this paper. The paper discuses the diverse environments, their interactions among themselves and the adverse interactions of man in the environments. The paper concludes by noting that the issue of “Man and His Environment,” is too all-embracing, to be given either a physical or socio-economic interpretation alone. It has to be approached comprehensively, as done in this paper, to have a deeper understanding of the concept.

MANAGING NIGERIA’S MULTIFARIOUS ENVIRONMENTAL LANDSCAPE IN THE 21ST CENTURY FOR SUSTAINABLE DEVELOPMENT, THROUGH A MULTI-DISCIPLINARY APPROACH (Published)

The recent widely-publicized renewed commitment of the Federal Government of Nigeria, to increased funding of university education in Nigeria, is a milestone in the history of educational management in Nigeria. The development coinciding as it were, with the 100 years of the country’s amalgamation, provides a unique opportunity for all patriotic and committed academicians and other intellectuals in Nigeria, to renew their own commitment to partnering with the governments and people of Nigeria, to combat the challenges of the nation and take the nation to a higher level in the nation’s quest for sustainable development. This is to be done through an appropriate deployment of specialized knowledge – a vital tool crucial to attaining sustainable development in the 21st century – a knowledge-based century. The paper is advocating that appropriate knowledge be deployed through a multi-disciplinary approach, to first of all, tackle the multifarious challenges of the country. Following the attainment of this crucial goal, knowledge can then be further deployed as appropriate, to take the country to the next level, in our quest for sustainable development. In going about the assignments, on which a clarion call is being made to Nigerian academicians, the environmental option, is being advocated. This is because its multifarious nature, will be most ideal not only to capture appropriately, all the diverse challenges of the country, but also all sectors of development, whose sustainability is dear to all well-meaning Nigerians and all lovers of Nigeria alike. The benefits of adopting the environmental approach to sustainable development, as well as the possible strategies that could be adopted, are spelt out, so also are the roles for the supervising agency of government for the universities

OUR ENVIRONMENT, THEIR ENVIRONMENTS AND THE SUSTAINABILITY OF OUR ENVIRONMENT (Review Completed - Accepted)

Environmentalists concentrate their efforts in seeing to it that sustainability is assured in the natural environment. The paper attempts to bring into the consciousness of environmentalist that a number of other environments exist that are in constant interactions with the natural environment and whose sustainability must also be assured in the overall interest of the sustainability of the natural environment. These other environments, are the man-made environments of socio-economic built and political/governmental environments. There is also the spiritual environment which humankind evolved with as a spiritual being.

Humankind must be in good standing in this spiritual environment to access the appropriate values that will enable them to assure sustainability in the natural and man-made environments. It is such values that will enable them to eschew all activities that border on corruption and violence, which are the bane of our environments.

This paper underscores the special importance of the natural environment, which is discussed as our environment – the environment of special interest to the environmentalists. It also highlights the importance of the man-made environments as their environments and the ways the activities in these man-made environments affect the natural environment. The paper discusses the efforts of human beings in managing the natural environment. It also highlights the challenges humankind is facing in this area. The paper is concluded with an admonition that humankind should endeavour to access the time-honoured values, without which no humankind can attain outstanding success, talk less of making community or nation attain sustainability of whatever type

CAN MOST THIRD WORLD COUNTRIES EVER GUARANTEE THE SUSTAINABILITY OF THE ENVIRONMENT (Review Completed - Accepted)

Five main types of environments are recognized. These are the natural environment, the socio-economic environment, the built environment, the political/governmental environment and the spiritual environment, which is an addition by the author to the list of environments. However, since these environments are in most cases affected by certain environmental challenges that are common to all of them and these environments are inter-dependent, with the happenings in one affecting the others, an “integrated environment” approach is adopted in this paper in discussing the environments, which are simply referred to as “the environment”, in most part of this paper.

The global environmental issues that are germane to sustainability of environment in which most of the third world countries are still lagging behind, are discussed. These issues are weighed against the back drop of the diverse sociological challenges facing these third world countries, many of which are not showing any sign of abatement within a foreseeable future. All these have led the author to the conclusion that most of these countries may remain in the doldrums for long, on the all-important issue of sustainability of the environment
