  • An empirical assessment of the Environmental Kuznets Curve for CO2 emissions in Ghana   Order a copy of this article
    by Michael Minlah, Richard Ayisi 
    Abstract: Ghana has achieved significant economic growth over the period 1971 -2009. However, it is widely acknowledged that economic growth has its negative environmental consequences. In very recent years environmental policy has been more directed towards correcting environmental ills such as deforestation, desertification and pollution which result from human activities. Issues of global warming and climate change have taken central stage in environmental policies of Ghana. This study investigated the determinants of CO2 emissions in Ghana within the Environmental Kuznets Curve analysis for the period 1971 to 2009. The long run analysis between the regression variables was established using the ARDL approach to co-integration. The study reveals an inverted N shaped relationship between CO2 and economic growth in Ghana. While urbanization, energy consumption and deforestation proved to be statistically insignificant in promoting carbon dioxide emissions in Ghana, trade openness and financial development were observed to reduce carbon dioxide emissions.
    Keywords: Environmental Kuznet Curve; Co2; Ghana.

  • LEED certification and market value of the firm   Order a copy of this article
    by Albena Ivanova, Marcel Minutolo 
    Abstract: This article extends signaling theory to research on voluntary green standards adoption and investigates the firms value in green buildings. The study analyzes the market valuation of investments in sustainable buildings, measuring the market reaction to three different types of Leadership in Energy & Environmental Design (LEED) announcements: (i) intent for application; (ii) achievement of certification; and, (iii) reinforcement of certification. The study hypothesizes the market will react differently to intent, achievement, and reinforcement signals. Empirical evidence shows a positive market reaction to LEED announcements in general, with positive but not statistically significant market reaction to the intent signals, and positive and statistically significant reaction to the achievement and reinforcement signals. Theoretical and practical implications are discussed.
    Keywords: LEED certification; separating equilibrium; signaling theory; standards; strategic management; event study; market value.

  • Climatic Changes and Vulnerability of Household Food Utilization in Malaysian East Coast Economic Region   Order a copy of this article
    by Md. Mahmudul Alam, Chamhuri Siwar, Basri Talib, Abu Wahid 
    Abstract: Sustainable food security at household level is one of the emerging issues for all nations. There are several factors such as social, economic, political, demographic, natural, and livelihood strategies that causes to the vulnerability of the status of household food security. Therefore examining the vulnerability of these factors is essential to identify the reason and recognize the most vulnerable communities. This study is an attempt to study on the vulnerability of the factors of household food utilization and its linkage with climatic changes in Malaysia. The study is based on primary data collected in the months of July October, 2012 through a questionnaire survey on 460 low income households from East Coast Economic Region (ECER) in Malaysia. The samples were selected from E-Kasih poor household database, based on cluster random sampling technique. The study found that the vulnerability of the factors of household food utilization has increased statistically significantly over the last five years period due to difference between rural and city food quality, occurrences of natural disasters, incidences of mosquitoes, insects, pest, etc., and diseases like dengue, malaria, heat stretch, cold, skin disease, etc. This study suggests that the food security programs need to be integrated with climatic change adaptation programs to ensure more effective and sustainable household food security in future, especially among the poor and low income group.

  • The influence of an Environmental Management System on the environmental worldviews of selected Namibian and South African in-service teachers   Order a copy of this article
    by Schalk Raath, Alex Tubawene Kanyimba, Luiza De Sousa, Barry Richter 
    Abstract: A recurring theme in contemporary environmental theory is the need for society to change to a New Ecological Paradigm. This paper reports on the influence of environmental management systems on the environmental worldviews of selected Namibian and South African teachers. A pre- and post-questionnaire survey using the New Environmental Paradigm scale was used to measure the underlying values of teachers to determine if the implementation of an environmental management system in the schools influenced their attitudes towards the environment. The findings revealed a positive inclination by the teachers to subscribe their personal and collective agency to pro-ecological tendencies. The MannWhitney test reveal a moderate size shift in worldview towards the pro-ecological and anti-anthropocentric tendencies of the New Ecological Paradigm showing that teachers still believe in the Dominant Social Paradigm. It is recommended that teachers and schools be encouraged to support the inclusion of an environmental management system to enhance sustainability practices.

  • Sustainability and Determining the Optimal Population Based on Water Resources in Mashhad, Iran   Order a copy of this article
    by Mohammad Rahim Rahnama, Lia Shaddel 
    Abstract: This study first evaluates Mashhads water resource sustainability, employing sustainable urban development models proposed by Haughton. Second, it determines the optimal number of population in 2016, both with and without the Dousti and Ardak dams. Results show that the Mashhad plain possesses only 2% of the total province groundwater although 65.97% of the urban provincial population live there. Furthermore, 92.7% of surface water comes from the Dousti dam, which is located 220km from Mashhad, and only 30% of domestic sewage is recycled. Using Haughton's theory of urban metabolism, Mashhad is thus not a sustainable city, as, including the Dousti and Ardak as water sources (dependence out of hinterland), it has a surplus population of 550,459 and excluding them, a surplus of 1,192,660 people.

  • Measurement of Environmental Sustainability Index and Its Association with Socio-economic Indicators in Selected Asian Economies: An Empirical Investigation   Order a copy of this article
    by Ajay Kumar 
    Abstract: The present study created the environmental sustainability index (ESI) for selected 22 Asian economies during 1990-2012. Composite z-score technique was applied to estimate country-wise ESI which explores the relative performance of these economies in environmental sustainability (ES). For this, 7 main components with 25 sub-indicators of environmental performance were chosen. Thereupon, it assessed the association among the ESI, Human Development (HD), economic development and social development using linear, log-linear and non-linear regression models. It implies that economic development, HD and social development have significant and complex association with ESI. It emphasizes that global and national policy makers, governmental agents and international development organizations need to take effective action to maintain ES. Otherwise, Worlds economies would be unable to achieve the path of sustainable economic development in future. It brings out some conclusive policy suggestions to maintain the environmental sustainability, economic development, HD, social development and sustainable development in Asian economies.

  • Mechanical characterization and flexural performance of eco-friendly concrete produced with fly ash as cement replacement and coconut shell coarse aggregate   Order a copy of this article
    by Prakash R, Thenmozhi R, S.N. Raman 
    Abstract: The aim of this study is to investigate the effect of adding fly ash, an industrial by-product and coconut shell, an agricultural waste on the mechanical and flexural characteristics of eco-concrete. The study focusses on density, compressive strength, tensile strength and flexural behavior of the coconut shell eco-concrete. Two different mixes are developed, one with coconut shell and the other with conventional aggregate and coconut shell as coarse aggregate. The cement content is replaced with Class F Fly ash at 0%, 10%, 20% and 30% by weight. The test result shows that the coconut shell concrete produced with 10% fly ash has recorded higher compressive, tensile strength than other proportions. Fly ash inclusion further reduces the density of coconut shell concrete. The higher deflection of coconut shell concrete before failure shows that it has failed in a ductile manner. The flexural behavior is comparable with other lightweight concretes. It is suggested that an eco-friendly, cost effective structural lightweight concrete can be produced by using coconut shell and fly ash.
    Keywords: Coconut shell aggregate; Fly ash; Eco-concrete; Compressive strength; Split tensile strength; Flexural behavior.

    by Sunday Olayinka Oyedepo, Isreal S. Dunmade, Tunde Adekeye, Ahme, B. Attabo, Olukunle C. Olawole, Philip O. Babalola, Joseph A. Oyebanji, Mfon Udo, Oluwaseun Kilanko, Richard O. Leramo 
    Abstract: In Nigeria, high and outrageous energy cost constitutes a serious challenge to all aspects of the economy. And this has been a subject of concern in the country over a period of time. A dependable and renewable energy source is of utmost desire to strengthen the nations economy and this urgent need cannot be overlooked. As a result of the erratic and expensive power supply to the national grid, it has become ultimately necessary to search for other inexpensive sources of energy to meet the ever increasing energy needs for rural and urban dwellers. This will in no small way improve the countrys national grid and consequently decrease rural-urban movement. The heavy reliance on natural gas to power electric power generation plants makes the country to be prone to power outages due to gas pipelines destruction resulting to in-sufficient gas supply by Nigerian Gas Company to most thermal power plants. In view of the above energy situation in Nigeria, this paper aimed at carrying out a comprehensive review on bioenergy technology option as a pathway to achieving sustainable energy development in the country. In this study, the potential, current progressive stages, and prospects of bioenergy conversion techniques, in the Nigeria context, are discussed. The barriers to bioenergy technology development in Nigeria with possible solutions are also presented. The study reveals that available information for the studied renewable energy option suggests bioenergy possess some potentials for the countrys sustainable energy development. Using biomass technology to generate power can help the country develop its energy sector more efficiently as the raw materials needed to feed the bioenergy plants are readily available in abundance in the country. Some are seen as waste such as agricultural and domestic wastes. Hence, developing the bioenergy capacity of the country will create wealth and employment opportunities for the unemployed sector in the country, generates electricity and production of domestic cooking gas across the rural and urban settlements in the country.

    by SELVAM RAMAKRISHNAN, Velavan R, Soundarrajan A 
    Abstract: Recently, renewable energy sources turned all attentions and became more attractive, due to increasing energy needs and factors like limited reserves, increasing energy costs and environmental pollution. As these sources dont cause any environmental pollution and have an unlimited supply, it is extensively utilized every day. Solar and wind are the two renewable sources considered in this paper. In renewable energy system, for maintaining the energy sustainability, a smart management scheme is required. The renewable sources like solar/wind is established to test the management system. The development of smart management scheme fulfills the power demand, since solar and wind are not reliable in stipulations of power quality and sustainability. In the renewable energy system, the generated power is collected on a common DC bus which is used for supplying to load. This DC power bus is operated in an exceedingly manner that, there is forever a base power available for permanent loads. Then, depending upon the availability of those power sources, the extra power demand is provided from either PV or wind source. The whole system is operated by a smart management system with the help of the fuzzy logic method. The fuzzy based smart management system determines the amount of power to be supplied based on the power information from a solar / wind system. The smart power management system will measure and track the available and generated maximum power from wind system, which increases the installed units efficiency. The result obtained will prove the effectiveness of the smart power management system.

  • Environment sustainable construction materials for garden-fresh and mechanical properties of high strength self-compacting concrete mixes with diverse mineral admixtures and water binder ratios   Order a copy of this article
    by Lavanya R, Murthi P, Karthikeyan V 
    Abstract: An experimental investigation was carried out to study the properties of self-compacting concrete (SCC) prepared with different mineral admixtures and waterbinder ratios. Fly ash, silica fume, and ground-granulated blast-furnace slag (GGBS) were used with waterbinder ratios of 0.3, 0.35, and 0.4. The mixes were designed for M60 grade of concrete and prepared with three steps of addition (5, 10, and 15%) of GGBS and silica fume and were made with four steps of fly ash (5, 10, 15, and 20%) as partial replacement of fine aggregate. For determining the fresh properties, slump flow, V -funnel, L-box, and U-box tests were conducted. The mechanical properties of mixes such as compressive strength, split tensile strength, and flexural strength were determined through standard tests. Compressive strength was found at the age of 1 day, 3 days, 7 days, 14 days, 28 days and 90 days, and the split tensile and flexural tests were performed at the age of 28 days. The test results revealed that in the SCC mixes, the flowability increases with increase in fly ash content, and the compressive strength decreases with increase in waterbinder ratio. The SCC mixtures in which fly ash was used replacing fine aggregate showed an increase in strength with age. It is concluded that a combination of fly ash, silica fume, and GGBS in SCC can be used to make a sustainable, eco-friendly construction material for a better tomorrow.

    by Murugaboopathy Rajagopal, Ganesan Karuppiah 
    Abstract: The purpose of this study was to investigate an effective method for the partial replacement of cement using waste materials to create green environmental sustainability in the construction industry. The aim was to develop a method for replacing the cement in concrete without changing its behaviour; tests were performed to predict the concretes strength, and they gave strong indications of the ideal concrete preparation method. The experimental variables were optimised using the Design-Expert 8.0.7.1 software package. Replacement was carried out with waste materials, such as groundnut shell ash (GSA; X1: 610%), ground granulated blast-furnace slag (GGBS; X2: 2050%) and polypropylene fibre (PPF; X3: 0.10.5%) for the improvement of the compressive, splitting tensile and flexural strengths of concrete using the response surface methodology (RSM). The optimum replacement of cement was observed at GSA of 7.58%, GGBS of 35% and PPF of 0.3%. Under this situation, the optimum compressive strengths of the concrete cube at 7 and 28 days were 18.7618.83N/mm2 and 30.9131.06N/mm2; the splitting tensile strengths of the cylinder at 7 and 28 days were 2.322.39N/mm2 and 432-4.41N/mm2 respectively; and the flexural strengths of the prism at 7 and 28 days were 3.373.49N/mm2 and 5.245.32N/mm2 respectively. In this experiment, most of the experimental values agreed relatively well with the predicted values. This optimisation process can be helpful in the construction industries to effectively reduce the utilisation of cement.

  • GREEN ENGINEERING PRINCIPLES FOR GLOBAL WATER QUALITY MONITORING USING IoT   Order a copy of this article
    by Kavitha Velusamy, Mohanraj Senkottaiyan 
    Abstract: Water is a vital resource without which most of the living beings cannot survive. The quality of drinking water depends on its source and storage conditions. Drinking water quality should meet the Environmental Protection Agency (EPA) regulations for quality assurance. Various purification methods are available to obtain pure drinking water. However, several industrialisation, globalisation, urbanisation, farming, and similar activities lead to drinking water contamination. Thus, the combined use of green engineering principles and internet of things (IoT) framework can aid simultaneous monitoring of water quality at different locations, at minimal costs and less need for manpower. This study proposes a system for real-time monitoring of water quality and detection of contamination, by using a wireless sensor network (WSN) to collect and transmit data. This system measures turbidity, pH, and temperature; these values are then processed using a controller and transmitted to the cloud through the WSN. The gathered data are highly accurate and can be accessed universally through the Internet by using a specific internet protocol address.

  • Energy Effective Routing Optimization using ACO-FDRPSO for Improving MANET Performance   Order a copy of this article
    by Rangaraj Jayavenkatesan, Anitha Mariappan 
    Abstract: Autonomous devices that are interconnected in an on demand fashion that communicate in wireless medium with the available energy constitute Mobile Adhoc Networks (MANET). Communication in these networks is restricted to lifetime of the nodes that inturn dependent upon the nodes battery power. Therefore optimization is necessary to prolong node lifetime and communication period. This work proposes a hybrid Ant Colony Optimization (ACO) combined with Fitness Distance Ratio Particle Swarm Optimization (FDR PSO) to optimize energy. ACO finds the energy efficient path in the network based on higher residual energy and FDR PSO minimizes energy consumption of the network, to enhance node lifetime which ensures energy efficient routing. Duty cycle algorithm collaborated with ACO swaps the nodes between active and sleep state depending upon their utilization. This prevents a node being active all time though it has no communication at that instant of time. The proposed hybrid technique (ACO-FDR PSO) is tested over a 100 node network scenario. The impact of varying number of nodes and their speed on the performance metrics such as throughput, packet delivery ratio, drop and residual energy have been analyzed using NS-2 simulator.

  • Quantification of environmental impacts of abrasive water jet cutting process through sustainability analysis   Order a copy of this article
    by Jayakrishna Kandasamy, Vimal KEK, Lakshimipriya Sethuram 
    Abstract: Sustainable development is the view that social, economic and environmental concerns should be addressed simultaneously and holistically in the development process. Sustainability has been applied to many fields, including engineering, manufacturing and design. Manufacturers are becoming increasingly concerned about the issue of sustainability. Appropriate trade-offs are often necessary, given the diverse interests of manufacturers and society. Relevant, meaningful, consistent and robust information on sustainable manufacturing must be available and utilized by organizations and their managers, if sustainability is to improve in manufacturing. In this perspective an effort has been made by conducting experimental studies on waste water obtained by machining mild steel plate using abrasive water jet cutting machine to examine the traces of metallic bodies and their impact on the environment. Studies were also conducted to calculate the embodied product energy of the process. Results from the experiment confirmed the presence of metallic particles and proved the necessity of treating these particles.
