3-D Printing of Open Source Appropriate Technologies for Self-Directed Sustainable Development

Abstract: The technological evolution of the 3-D printer, widespread internet access and inexpensive computing has made a new means of open design capable of accelerating self-directed sustainable development. This study critically examines how open source 3-D printers, such as the RepRap and Fab@home, enable the use of designs in the public domain to fabricate open source appropriate technology (OSAT), which are easily and economically made from readily available resources by local communities to meet their needs. The current capabilities of open source 3-D printers is reviewed and a new classification scheme is proposed for OSATs that are technically feasible and economically viable for production. Then, a methodology for quantifying the properties of printed parts and a research trajectory is outlined to extend the existing technology to provide complete village-level fabrication of OSATs. Finally, conclusions are drawn on the potential for open source 3-D printers to assist in driving sustainable development.

Tools for Sustainable Product Design: Additive Manufacturing

Abstract: The advent of additive manufacturing technologies presents a number of opportunities that have the potential to greatly benefit designers, and contribute to the sustainability of products. Additive manufacturing technologies have removed many of the manufacturing restrictions that may previously have compromised a designer’s ability to make the product they imagined, which can increase product desirability, pleasure and attachment. Products can also be extensively customized to the user thus, once again, potentially increasing their desirability, pleasure and attachment and therefore their longevity. As additive manufacturing technologies evolve, and more new materials become available, and multiple material technologies are further developed, the field of product design has the potential to greatly change.This paper examines aspects of additive manufacturing from a sustainable design perspective could become a useful tool in the arsenal to bring about the sustainable design of consumer products.

In fact the capability of this technology offers great tools of how the water quality monitoring and managing can be operationalised in this country. Potential application and management is identified in promoting concept of sustainable water resource management. In conclusion remote sensing and GIS technologies coupled with computer modelling are useful tools in providing a solution for future water resources planning and management to government especially in formulating policy related to water quality.

The Role of HR in Achieving a Sustainability Culture

Abstract: An organization’s Human Resource function can be instrumental in facilitating a comprehensive approach for creating a culture of sustainability and environmental stewardship. As such, it is recommended that an organization’s Sustainability Coordinator work more closely with the organization’s Human Resource executive. This idea might be considered a new area of focus for the practical implementation of sustainable development in a company. The strategy involves making significant changes to the organization’s systems for: recruiting applicants, selecting new employees, conducting new employee orientation, conducting performance evaluations, determining employee compensation, creating a succession planning process, providing employees with training and development, and mentoring employees and managers. It also involves creating a win-win-win collaboration among multiple stakeholders who are in conflict with each other. Numerous examples are provided demonstrating how a focus on each of the HR systems has helped organizations to create a sustainability culture.

Application of Value Beliefs Norms Theory to the Energy Conservation Behaviour

Abstract: This paper tries to explain the conservation behaviour as one of the aspects of sustainable consumer behaviour. The theory of Values Beliefs Norms is chosen as the theoretical framework of this research. This theory discusses that the conservation behaviour is adopted owing to the activation of the personal norms by the values and the beliefs of individuals. A study of 703 individuals has been made in an attempt to test the model of this study. The data is analysed through the structural equations method. The results have enabled us to validate the VBN model in the Tunisian context.

Poverty Eradication, Millennium Development Goals and Sustainable Development in Nigeria

Abstract: The Millennium Development Goals (MDGs) are targeted at eradicating extreme hunger and poverty in the 189 member countries of the United Nations (UN). Nigeria as a member of the United Nation keyed into the implementation of the framework of the goals by formulating the National Economic Empowerment and Development Strategy (NEEDS), NEEDS as a policy is targeted at eradicating poverty and bringing about sustainable development. This is done through the establishment of Agencies like the National Poverty Eradication Programme (NAPEP). However, the scourge of poverty is till been felt by the majority of the citizens of the country who do not have access to primary health care, water and food. This paper analyses the effect of eradicating poverty in Nigeria via the instrumentality of the MDGs and concludes that government at various levels must come up with genuine poverty reduction programme if the challenges of poverty must be tackled.

Inflation and Economic Growth in Nigeria

Abstract: The main purpose of this study is to ascertain the existence (or not) of a relationship between Inflation and economic growth in Nigeria. The methodology employed in this study is the cointegration and Granger causality test. Consumer price index (CPI) was used as a proxy for Inflation and the GDP as a perfect proxy for economic growth to examine the relationship. The scope of the study spanned from 1970 to 2005. A stationarity test was carried out using the Augmented Dickey-Fuller test (ADF) and Phillip-Perron test (PP). and stationarity found at first difference at 1% and 5% level of significance. The Johansen-Juselius co-integration technique employed in this study proved to be superior to the Engle and Granger (1987) approach in assessing the co-integrating properties of variables, especially in a multivariate context. The result of the test showed that for the periods, 1970-2005, there was no co-integrating relationship between Inflation and economic growth for Nigeria data. Further effort was made to check the causality relationship that exists between the two variables by employing the VAR-Granger causality at two different lag periods. The results showed the same at different lags. The first test was conducted using lag two (2) and in the result unidirectional causality was seen running from Inflation to economic growth. Further test at lag four (4) was carried out and it only supported the first by also indicating a unidirectional causality running from Inflation to economic growth. Various studies as reviewed in the literature came out with the result that high inflation is and has never been favourable to economic growth. Hence, the study through the empirical findings maintain the fact that the causality that run from inflation to economic growth is an indication of relationship showing that Inflation indeed has an impact on growth.

Sustainable Development in Malaysia: A Case Study on Household Waste Management

Abstract: Sustainable development (SD) is a concept which first originated in the 1970s when the developed world undertook massive development project in terms of cutting and clearing forests and constructing high rising buildings and spacious highways. Development of a country is essential to meet the needs of its people and to provide people with the latest infrastructure, high rising buildings and recreation facilities. However, the development process concerns the world community as it affects the natural environment. The ecological balance breaks down and environmental degradation occurs at an alarming rate. Therefore, the world community started thinking about protecting the environment while implementing development activities. Environmental degradation also occurs from intensive industrialization of a country. Therefore, to protect the environment, the world community proposed sustainable development. Sustainable development has three components: economic development; social development; and environmental protection. A sustainable development project requires that in any development project, these three components of SD must be taken into consideration and implemented properly so that the environment is not adversely affected. This paper focuses only on a small aspect of environmental protection, that is, proper management of household waste. This paper discusses how household waste in Malaysia can be converted into vermicompost for use in plantations and agriculture. The production of vermicompost may reduce the amount of organic waste in the country and help to maintain a clean and fresh environment. Vermicompost can also reduce emission of methane gas which causes global warming. Descriptive and analytical research methodology has been applied in this research paper.

Building Failure and Collapse in Nigeria: the Influence of the Informal Sector

Abstract: The occurrence of building failure and collapse has become a major issue of concern in the development of this nation as the magnitudes of this incident are becoming very alarming. This paper therefore examines the incidents of building failure/collapse in Nigeria. By focusing on six major states from each of the six geo-political regions of the country, the paper examined the contributory role of the informal sector to this decadence. The study indicated that the building failure and collapse stem principally from hasty construction, low quality workmanship, poor supervision, inexperience (use of incompetent hands), ignorance, evasion/ non-compliance with building regulations and non enforcement of building quality, standard and control on construction site/market. This study has revealed that more than 70% of the reported cases of building collapse in Nigeria stemmed from the informal sector. It further showed that 70-0%, 23-3% and 6.7% of the reported cases occurred in private, public and corporate organizations respectively. In this paper, it is concluded that it is important to educate or giver further advice to the government and the governmental agencies to be proactive to their duties in order to curb/reduce this negative image.

Tackling Causes of Frequent Building Collapse in Nigeria

Abstract: A building, once properly constructed is expected to be in use for a very long time. Although every society has its own problems and Nigeria is not an exception yet the very recent challenges of buildings collapsing in various locations have been giving the various arms of government and the people of Nigeria sleepless nights in view of the enormous loss of huge investments in housing, properties and human life. The major challenge on the issue of building collapse is that individuals differ radically from one another on the professional to blame as the major cause of the collapse of a building. This study reviews current challenges in the building industry in relation to collapse of buildings, loss of lives and properties. Data for the study were obtained through structured questionnaires administered to landlords and professionals in the construction industry in addition to academia in the built environment. Historical data of past collapsed buildings in Nigeria were also discussed. Findings from the three prominent groups were varied. First, building experts blamed building collapses on the use of low quality building materials coupled with employment of incompetent artisans and weak supervision of workmen on site. Second, public opinion revealed that the blames of building collapse were due to non-compliance with specifications/standards, use of substandard building materials and equipments and the employment of incompetent contractors. Third, opinion of the academia on remote causes of building collapse showed that the route causes are mainly the non-enforcement of existing laws and endemic poor work ethics of Nigerians at large. The study recommends that the press should lay more emphasis on educating the public at large on the dangers of the collapse of a building and less on public emotions. In addition, government should, on one hand, embark on proactive steps by mustering enough political will to allow the Town Planning Authorities to perform their functions unfettered and on the other hand, provide the legal framework that can improve and ensure smoother, less time-consuming and less burdensome ways to conduct business in the functioning of law courts.

Organic Farming as A Development Strategy: Who are Interested and Who are not?

Abstract: Much evidence shows that implementation of organic farming (OF) increases productivity in the Global South, and that it will be possible to feed a growing world population with food produced in OF systems. OF is explored, analysed and discussed in relation to the principles of Ecology, Health, Care and Fairness as enunciated by IFOAM, as a developmental strategy. Major financial powers are involved in the agro-related industries. A number of civil society-based organisations point to the major negative side effects of the trade with and use of agro-chemical products environmentally and in the further deepening of the gaps between rich and poor. The MDGs target the environmental sustainability explicitly, and OF is regarded as being a relevant strategy to meet many goals. A global development strategy is needed that explicitly includes future generations, ecosystems, biodiversity and plant and animal species threatened by eradication.

Factors Influencing the Willingness to Pay for Entrance Permit: The Evidence from Taman Negara National Park

Abstract: Non-market techniques such as Travel Cost Method (TCM) and Contingent Valuation Method (CVM) are commonly used to estimate the economic benefits of outdoor recreation. This study applied the CVM, with Willingness to Pay (WTP) as the elicitation method, to investigate the pattern of willingness to pay among visitors of Taman Negara National Park (TNNP). In applying CVM, the respondents were asked on the maximum amount they were willing to pay to enter this park. Data were obtained using closed-ended questionnaires through interview. About 196 visitors were involved in the study. This study used multiple regressions (MR) to investigate factors that determine WTP for entrance permit in TNNP. This study found that the WTP was positively related to several important factors; and these factors include nationality, income, education and marital status. All these factors can help to explain the WTP for entrance permit at TNNP. Approach in determining WTP for entrance permit will help park authorities to be more financially self-sufficient. In addition, it will generate more income, and thus more efficiency in operating and maintaining the national parks.

Transport Infrastructure, Energy Consumption and Economic Growth Triangle in India: Cointegration and Causality Analysis

Abstract: The paper explores the nexus between transport infrastructure (road and rail), energy consumption (oil and electricity) and economic growth in India over the period 1970-2007. Using cointegration and Granger causality test, the paper finds a unidirectional causality from transport infrastructure to economic growth, a unidirectional causality from economic growth to energy consumption and a unidirectional causality from transport infrastructure to energy consumption. The paper at the end suggests that energy and transportation policies should recognize the transport- energy consumption- growth nexus in order to maintain sustainable economic growth in the country.

Globalization, Poverty and Environmental Degradation: Sustainable Development in Pakistan

Abstract: The purpose of the present research is to investigate the impact of globalization, and poverty along with other socio-economic and demographic factors (such as industrialization, fertilizer use, urbanization, population growth and education) on environmental degradation in Pakistan. The study analyzed simultaneously the effect of environmental degradation, globalization and poverty on economic growth as well. The Study found a long run relationship between economic growth, environmental degradation, globalization, poverty and other socio-economic and demographic factors mentioned above. The study displayed that increased globalization caused to decrease the rate of environmental degradation and played positive roll on economic development in Pakistan. The analysis suggested that poverty may cause to increase environmental degradation and may slower the process of economic development if it would not be alleviated. If we want to attain sustainable development in Pakistan, we have to globalize our resources, reduce poverty, own green technologies, control growing population and urbanization rate.

An Assessment of Recent Changes in the Niger Delta Coastline Using Satellite Imagery

Abstract: In Nigeria, there is dearth of studies on recent changes on accelerated marine processes along the national coastlines despite their importance as ports for navigation and marine commerce as well as a bridge for aquatic and terrestrial life.This study, which deals with a time series analysis of recent changes in the Niger Delta Coastline using Satellite Imagery is an attempt at filling this gap. Landsat TM images of 1986 and Landsat ETM+ of 2003 both covering the Niger Delta area of Nigeria were used for this study and the images were processed using Erdas Imagine Version 8.7 and Arc Info 9.1 for the GIS operations. The results of the analyses show among other things that coastline erosion was dominant over accretion of sediment deposition. Also that the total area of observed changes along the coastlines was 46.535sq.km. Of this, 27.65sq.km (59.43%) constitutes eroded area, and 40.57% representing 18.88sq.km of the area showed coastal sediment accretion.

Forecasting with univariate time series models : a case of export demand for Peninsular Malaysia’s moulding and chipboard.

Abstract: This study determines a suitable method from the univariate time series models to forecast the export demand of moulding and chipboard volume (m³) from Peninsular Malaysia using the quarterly data from March 1982 to June 2009. Export demand for moulding and chipboard were estimated using univariate time series models including the Holt-Winters Seasonal, ARAR algorithms and the seasonal ARIMA models. The seasonal ARIMA (1, 0, 4) X (0, 0, 1, 0)4 model produced the best forecast at the lowest forecast errors of MAPE, MAE and RMSE at 18.83%, 32730.8 and 35282.13, respectively. It forecasts the volume (m³) of moulding and chipboard for export to reach more than 150000 m3, and it is expected to be within range of 100000 to 250000 m3 at 95% confidence level. The forecasts assist in decision making process and facilitate a short-term marketing plan to meet the export demand from international market.

The Impact of ISO 14001 Environmental Management System (EMS) Implementation on SMEs Performance: An Empirical Study in Malaysia

Abstract: Despite the growing interest in examining ISO 14001 EMS implementation and firm's performance, little attention has been devoted especially among the SMEs in Malaysia. Based upon 61 responses questionnaire survey, this study examines the relationship of ISO 14001 EMS implementation to Malaysian SMEs performances. The findings of this study confirm that ISO 14001 EMS implementation has a positive and significant relationship with SMEs's performance. This finding is consistent with the environmental management literature mostly published in the developed countries. This study is important as the empirical results provide an indicator to encourage other SMEs which has no EMS in place to consider joining the bandwagon. Since the ISO 14001 standard is still on a voluntary basis in Malaysia, this study able to give empirical evidence on SMEs performance appears to be critical at this juncture noting the fact that SMEs contributes to the largest business establishments in Malaysia.

Sustainable Urbanization’s Challenge in Democratic Republic of Congo

Abstract: In the context of rapid urbanization in Democratic Republic of Congo, overpopulation in Kinshasa’s city increasingly carries out chaos, inequalities, poverty, environmental degradation, open spaces loss , socio - economic tension, and spontaneous settlements and sprawl. This rapid urban growth occurs without planning and productive employment compounded by weak government involvements. These crisis situations put to the forefront sustainable urbanization as a priority issue for urban development with reference to the globalization and technology. This requires reconsidering urbanization process to stimulate economic growth and mobilize resources at local, national and global levels. A comprehensive reform based on an integrating vision of governance and collective commitment to manage efficiently natural resources. The paper reviews pragmatic approaches in urban planning decision in its whole refers to the dynamics of management, qualification and transformation of the city. The paper presents urban renewal as remedial action holding opportunities to improve environmental quality.

Determining suitable probability distribution models for annual precipitation data (a case study of Mazandaran and Golestan provinces)

Abstract: Statistical distributions can be used for data development in shortage data situations, as in many part of Iran station. The aims of this study are select the best frequency distribution to estimate average annual precipitation and assess the effects of data length on the selection of suitable distribution. Therefore 65 stations data of Mazandaran and Golestan provinces were analyzed. Relative residual mean square (RMS) was used to determine the best fitted distribution to any annual series and precipitation was estimated for different return periods. Relative frequency of first classes of fitted distributions showed that normal and Pearson distributions decreased and Gumbel distribution had more fitness with data series by increasing statistical period length. The best-fitted distribution is Pearson with 15-year data; log Pearson for 20, 25 and 30-year periods. Based on Moment method and total given scores, two-parameter normal distribution has the best fitness in all statistical periods.

Economic value of ecotourism to local communities in the Nigerian rainforest zone

Abstract: This study estimates community willingness to contribute for an ecotourism improvement project and its determinants in the Okwangwo Division of the Cross River National Park, Nigeria. Personal interviews were conducted with 150 households in three communities located in the proximity of the park. The study showed that the respondents were willing to contribute an average of about one percent of their mean annual income. Determinants of the respondents’ willingness to contribute amount was estimated with the aid of the ordinary least squares and tobit models. The results showed that willingness to contribute were influenced by factors such as income, distance of respondents’ residence to the park, post-high school education, occupation and membership of an environmental conservation group. The results generated from this study will contribute to the knowledge of sustainable management of ecotourism projects. Keywords: Ecotourism, willingness-to-contribute, Cross River National Park, Contingent valuation

Representing a Sustainable World – A Typology Approach

Abstract: This paper presents, in the form of a typology, the findings of a current research project concerned with what it means for there to be a sustainable world. The typology if framed around key sustainable world dimensions and how each of these is considered in terms of Reformist and Transformational approaches to giving meaning to a sustainable world and how this might be achieved. Key themes evident in the typology are discussed namely the primary sustainable world goal of flourishing life, the anthropocentrism-ecocentrism divide, approaches to human interests satisfaction, and optimisation vs resilience living. The paper notes the mere descriptive nature of the typology and concludes with some thoughts on ways in which the typology might be critiqued to identify which approach, Reformist or Transformational, is more likely to see the primary goal of a sustainable world achieved.

Empirical Study of the Relationship between Ownership Structure and Firm Performance: Some Evidence of Listed Companies in Tehran Stock Exchange

Abstract: The study of effective factors seems essential since, the operation of profiting entities is very important in the decision of internal and external organization users. The effect of various factors on the assessment scale of operation was measured in different researches, e.g. the structure of ownership. In this study, the relationship between three kinds of various structures of ownership including the structure of shareholder's ownership and other firms and the structure of state ownership Q Tobin's operation scale of listed firms in TSE was considered. The effect of firm's age and size has considered as two control variables on the Q Tobin's operation scale. In this study, the statistical population is listed firms in Tehran Stock Exchange (TSE).Theories are tested by multilateral Regression on the basis of T and F statistics. Finding shows that Q Tobin operation scale has significant relationship with two kinds of investment organization's ownership scale and other companies and state ownership, but it does not have significant relationship with minor shareholder's scale. Age and size of firms do not effect on Q Tobin operation scale as two control variables.

Daylighting Strategy for Sustainable Schools: Case Study of Prototype Classrooms in Libya

Abstract: Over the last few years, topics related to sustainable development and energy saving in Western countries led to several research projects aiming to promote the amount of natural daylight used in school buildings. The same issues arise now in Libya, especially those concerning the use of natural daylight. The promotion of natural daylight in the classrooms saves electrical energy and improves the working conditions for both teachers and students. The extreme solar heat in Libya has always been an imperative factor in relation to building heat. Especially during the period from June to August great care is given to avoid overheating while still preserving the use of natural daylight.

Towards a sustainable use of water at home: understanding how much, where and why?

Abstract: This paper presents the findings which have arisen from a literature review carried out at the beginning of a three year CONACYT sponsored PhD project, investigating water-related activities in the home and the growing need to understand user behaviour when consuming water. It illustrates how habits and routines emerge and develop. It then considers how perceptions of consumption and hygiene influence domestic water use, reflecting on how social, psychological and technological aspects influence domestic water use. The paper concludes by identifying a number of research questions which will be investigated through the remainder of the project.

An Assessment of Thermal Comfort and Users’ Perceptions of Landscape Gardens in a High-Rise Office Building

Abstract: There is a great need to reduce energy consumption in high-rise office buildings due to escalating environmental problems such as Urban Heat Island effect and global warming. The creation of landscape spaces in high-rise buildings today is not only for reducing building heat but to provide views and psychological get-away spaces for its occupants. This paper focuses on thermal comfort and users’ perception of three different landscape gardens in a 21-storey high-rise office building in Penang, Malaysia. The four parameters of thermal comfort that were measured are: air temperature, wind velocity, humidity, and solar radiation. In addition, a questionnaire survey was conducted to evaluate occupants’ perceptions of comfort, use of the garden space and landscape preference. The findings from the field measurement reveal significant differences in all four thermal comfort parameters measured in the three landscape gardens. However, users only perceived lighting and wind velocity to be different.

The Place of the Family House in Contemporary Oyo Town, Nigeria

Abstract: Every culture produces its own house-form, highly reflective of the history and lifestyle of its people. The family house is a symbol of social identity and family recognition; the need to preserve people’s culture and history through their house is crucial to achieving sustainable housing and decent livelihood. One major concern of urban sociologists and anthropologists, and those in housing related disciplines, is how to provide adequate shelter for the wellbeing of the people. This study thus attempts to examine the place of the family house in Oyo town, Nigeria. A survey of existing family house structure was conducted on households and their housing peculiarities to determine residents’ dwelling preferences. The study showed that despite noticeable inadequacies and deplorable conditions exhibited by most dwellings in Oyo town, the people had strong inclination towards their houses. The study concludes that traditional architecture is not opposed to modernity if both are mutually and rationally initiated. To achieve sustainability in housing, relevant aspects of people’s culture and history, inherent in their dwellings should be incorporated into contemporary housing development.

Eco-impact of shopping bags : consumer attitude and governmental policies

Abstract: Shopping bags are a symbol of the throw-away society, its deliberation on eco-impact is reasonably high compared to other products. Life cycle assessment (LCA) is used to throw light on the eco-impact of non-woven and woven bags. Life Cycle Assessment comprises of different stages of a product, from its manufacturing phase to end-of-life phase. Government and consumers are accountable primarily for the end of life phase covering reuse, recycle and disposal to landfill. The consumer plays a vital role here in terms of opting between the usage and disposal criteria which alleviates eco-impact and also the government assumes significant importance in providing the appropriate recycling strategies and policies. In this research work, an attempt has been made to elicit the consumer’s attitude towards reuse, recycle and disposal to landfill options and to elucidate the existing governmental policies on recycling as well as willingness of people to support them by means of a research questionnaire survey conducted in China, Hong Kong and India, amongst different user groups of various shopping bags.

Adaptation to the Impact of Climatic Variations on Agriculture by Rural Farmers in North-Western Nigeria

Abstract: The impact of climatic variations on crop yields and the adaptation by farmers in north-western Nigeria are examined using the modeling approach and farm surveys. Accordingly, regression models which relate climate data to crop yields were constructed. The results showed that rainfall has a positive relationship with crop yields in the region and explained over 70 percent of the variations in the yields of sorghum, millet and maize, all of which were significant at the 0.05 level. Evaporation also had a significant but inverse relationship with crop yields. Other climatic elements in the experiment provided minimal levels of explanation. The farm surveys found that rural farmers in north-western Nigeria were quite innovative when it comes to adapting to drought. The study concluded that the impact of climatic variations on crop yields in north-western Nigeria can be substantial especially under drought conditions. The need to update farmers’ adaptive strategies is emphasized.

Valuation Inaccuracy: An Examination of Causes in Lagos Metropolis

Abstract: Valuation plays essential roles in the property market either for loan purposes, sale transactions, and portfolio management or performance measurement. Previous studies had established that there was valuation inaccuracy everywhere in the world, including Nigeria. This study examined the causes of such inaccuracies. Survey approach was used in carrying out the study. 150questionnaire was retrieved out of 300 questionnaire (i.e. 50%) administered on the respondents selected from the Nigerian Institution of Estate Surveyors and Valuers’ Directory and this was used for the analysis. Descriptive statistics was employed in the analysis of the data collected. The study revealed that valuation inaccuracy in Lagos Metropolis result from dearth of market evidence (data), use of outdated valuation approach and clients’ influence. The study established that Valuers in the metropolis engaged in general practice. The paper recommends that Nigerian Valuers should join hands in providing centrally organised databank which will reduce the level of inaccuracy in valuation.
