  • Contributions of sustainability science to the study of environmental
           health problems
    • Authors: Walter Alfredo Salas-Zapata; Leonardo Salas-Zapata
      Pages: 347 - 367
      Abstract: From the ontological point of view, environmental health problems do not differ from problems of unsustainability. This leads us to think that sustainability science could contribute to resolve important questions that studies on environmental health are not resolving. A literature review was made in order to analyse the scope and limitations of studies on environmental health problems. Based on the characteristics of environmental health studies, we highlighted some examples of questions that are being ignored and analysed four contributions that sustainability science could make to solve them. These contributions come from three key components of sustainability science: (1) the unit of analysis—social–ecological systems, (2) a theory—resilience theory and, specifically, social–ecological resilience, (3) and the approaches of complex systems and transdisciplinarity. From a sustainability science perspective, four contributions could be made: environmental health problems are redefined as social–ecological systems; environmental health is assumed to be the result of adaptation processes; the environment and society are recognized as systems, not as matrices of factors; and human action acquires content and structure and, in turn, explains the behaviour of environmental health problems.

  • A review of steel slag usage in construction industry for sustainable
           development
    • Authors: İsa Yüksel
      Pages: 369 - 384
      Abstract: Use of by-products from the steelmaking process can play an important role in achieving sustainable development. The available literature suggests that the use of iron and steel industry slags as mineral admixture or partial replacement of cement improves the microstructure of the concrete as well as its mechanical and durability characteristics. This paper reviews utilization of steel slag (SS) in the construction industry by considering current and possible future utilization fields, advantages of SS usage, and problems associated with its use. Strength and durability evolution of concretes or mortars containing SS in different ratios as aggregate or cement replacement material, combined use of ground granulated blast furnace slag with SS, and some relatively new fields of utilization of SS are also addressed. Improvements in and results of SS utilization in cement and concrete are discussed by addressing its beneficial effects. This article could help researchers to understand the recent developments in evaluation of SS in the construction industry.

  • Assessment of physicochemical characteristics of Ganga Canal water quality
           in Uttarakhand
    • Authors: Gagan Matta; Sachin Srivastava; R. R. Pandey; K. K. Saini
      Pages: 419 - 431
      Abstract: Assessment of physicochemical parameters of Ganga Canal water was carried out during 2012–2013 at Haridwar (Uttarakhand) with two different sites, i.e., Bhimgoda Barrage (site 1—control site) and Bahadrabad (site 2—contaminated site), where canal water flows with loads of pollution from highly commercial and industrial areas. During investigation, maximum turbidity (287.72 ± 56.28 JTU), total solids (1167.60 ± 303.90 mg l−1), free CO2 (1.88 ± 0.22 mg l−1), total hardness (60.14 ± 1.13 mg l−1), pH (7.1 ± 0.13), nitrate (0.048 ± 0.010), nitrite (0.019 ± 0.001), biochemical oxygen demand (2.866 ± 1.098), chemical oxygen demand (6.8 ± 2.61) and phosphate (0.087 ± 0.015), while minimum velocity (1.71 ± 0.19 ms−1), transparency (0.12 ± 0.08 m) and dissolved oxygen (7.95 ± 0.44 mg l−1) were recorded in monsoon season at site 2 in comparison with site 1. The mean values of these parameters were compared with WHO and ISI standards and found significant differences (p < 0.05) in the mean values of turbidity, total solids, pH, dissolved oxygen, free CO2 and total hardness with sampling sites. The turbidity of both the sites 1 and 2 was recorded above the permissible limit. Turbidity of site 2 is much higher than of site 1, so it is counted as more polluted. The values of the studied parameters were more during monsoon season and summer season at site 2 as compared to site 1. The results indicated that most of the physicochemical parameters from Ganga Canal system were within or at periphery in comparison with permissible limit of ISI and WHO for drinking water and therefore may be suitable for domestic purposes, but it requires perceptible consideration due to intense changes in climate and increase in pollution.

  • Effectiveness of EMS in Tunisian companies: framework and implementation
           process based on ISO 14001 standard
    • Authors: Mohamed Turki; Emna Medhioub; Moneem Kallel
      Pages: 479 - 495
      Abstract: This paper reports environmental analysis results of food and tannery Tunisian companies to identify the features of environmental management system (EMS) that is implemented recently. EMS via ISO 14001 has become one of the principal tools used by companies to handle environmental aspects and impacts through their various complex activities interacted with environment. While several companies have implemented and maintained a formal EMS, it has related mainly to their benefits in short term without responding to the sustainable development recommendations and practices. This study focuses on the strong linkage between the EMS effectiveness of food–tannery Tunisian companies and sustainability. A proactive environmental management approach is proposed and adopts a qualitative and quantitative assessment for factor analysis. It provides a strategic EMS framework and principles for sustainability to evolve the future enterprises’ benefits that has a clear influence on environmental performance in long term.

  • Agricultural innovation and adaptation to climate change: empirical
           evidence from diverse agro-ecologies in South Asia
    • Authors: Gopal Datt Bhatta; Hemant Raj Ojha; Pramod Kumar Aggarwal; V. Rasheed Sulaiman; Parvin Sultana; Dhanej Thapa; Nimisha Mittal; Khemraj Dahal; Paul Thomson; Laxman Ghimire
      Pages: 497 - 525
      Abstract: While impacts of climate change on agricultural systems have been widely researched, there is still limited understanding of what agricultural innovations have evolved over time in response to both climatic and non-climatic drivers. Although there has been some progress in formulating national adaptation policies and strategic planning in different countries of South Asia, research to identify local-level adaptive strategies and practices is still limited. Through eight case studies and a survey of 300 households in 15 locations in India, Nepal and Bangladesh, this paper generates empirical evidence on emerging agricultural innovations in contrasting socio-economic, geographical and agro-ecological contexts. The study demonstrates that several farm practices (innovations) have emerged in response to multiple drivers over time, with various forms of institutional and policy support, including incentives to reduce risks in the adoption of innovative practice. It further shows that there is still limited attempt to systematically mainstream adaptation innovations into local, regional and national government structures, policies and planning processes. The paper shows that the process of farm-level adaptation through innovation adoption forms an important avenue for agricultural adaptation in South Asia. A key implication of this finding is that there is a need for stronger collaborations between research institutions, extension systems, civil society and the private sector actors to enhance emerging adaptive innovations at the farm level.

  • Simulating spatial pattern of urban growth using GIS-based SLEUTH model: a
           case study of eastern corridor of Tehran metropolitan region, Iran
    • Authors: Hashem Dadashpoor; Mahboobeh Nateghi
      Pages: 527 - 547
      Abstract: Tehran metropolitan region (TMR) has experienced rapid urbanization in the last few decades. This accelerating urbanization trend mainly arising from high natural population growth and rural–urban migration along with rapid socioeconomic changes formed unplanned and uncontrolled urban expansion in peri-urban areas and resulted in degrading environmental quality and considerable changes in the urban landscapes of the TMR. Thus, the main objective of this research is to model spatial pattern of urban growth in eastern corridor of TMR using GIS-based SLEUTH model and the prediction of future developments of the region from 2014 to 2060. The SLEUTH is one of the most powerful models for urban growth modeling. This model analyzes the spatial pattern of urban growth based on historical data obtained from satellite images of 1987, 2003, 2011, and 2014. The results indicate that the most important factors affecting the urban growth are slope resistance and road gravity. The slope resistance is the highest coefficients value, which illustrates the limiting influence of the slopes on general trend of urban growth in eastern corridor of the TMR. The road gravity stands in second place where it displaces orientation of linear form of outlying pattern alongside the transportation network; it represents that the main pattern of urban growth in peri-urban areas of the region have a linear nature and edge expansion due to slope resistance and road-influenced growth, while spread, diffusion, and breed coefficients display low probability of new spreading center and spontaneous growth in the study area. In addition, the prediction of urban growth for 2020–2060 revealed that urban expansion which was 41,500 ha in 2014 will increase to 179,400 ha in 2060 with noticeable growth rate of 145.6 %. Comparing study area and other researches indicate that the urban growth happens in high rate in eastern corridor. One of the main reasons of this growth goes back to the formation of the second homes for residents of Tehran metropolitan city.

  • Employment implications of stricter pollution regulation in China:
           theories and lessons from the USA
    • Authors: Dong Guo; Satyajit Bose; Kristina Alnes
      Pages: 549 - 569
      Abstract: While the goal of reducing environmental impact has become an urgent imperative for Chinese leadership, the central and potentially competing objective for policy makers and planners remains economic growth and job creation. This paper systematically examines the perceived trade-offs between pollution control regulation and employment at the microeconomic and macroeconomic scale. We synthesize the theoretical literature on the employment impact of pollution control regulation at the firm, industry, and economy levels and summarize the theoretically sufficient conditions for employment-enhancing regulation. The paper examines the US experience with the impact of pollution control on job growth in the 1980s and 1990s and draws out the mechanisms through which job growth and pollution control can be congruent, examining their adaptability to the Chinese context. Specifically, this paper highlights the importance of targeting regulations toward sectors where labor costs represent a small portion of overall costs or sectors with low labor intensity. We demonstrate that in the Chinese context, a transition to an economy with a higher proportion of tertiary output is likely to facilitate a joint strategy of stringent pollution control combined with job growth.

  • Separate waste collection in Italy: the role of socio-cultural factors and
           targets set by law
    • Authors: Massimiliano Agovino; Antonio Garofalo; Angela Mariani
      Pages: 589 - 605
      Abstract: The aim of this paper was twofold: on the one hand, we analyse the results achieved in terms of percentages of separate collection in Italy by testing the effectiveness of Legislative Decree 152/2006 in improving the separate collection process; and on the other hand, we investigate on some of the factors, related to the sociocultural local context, that could explain the different impacts of the law in the three macro-areas considered (North, Central and South Italy). To this purpose, an econometric analysis on the Italian regions for the 1996–2013 period is performed, comparing the period before (1996–2006) and after (2006–2013) the date of entry into force of the new law. The results show the effectiveness of Legislative Decree 152/2006 in promoting separate collection, although a regional difference in terms of separate collection rate is observed. Northern regions proved to be more dynamic and reactive to the above-mentioned legislation, while Central and especially Southern regions achieved poorer results in moving to higher separate waste collection rates. Finally, our work provides evidence on some local factors that may have hampered an effective policy implementation in Southern regions, among them, the presence of criminal activities and the lack of citizen participation in politics.

  • The methylic versus the ethylic route: considerations about the
           sustainability of Brazilian biodiesel production
    • Authors: Alexandre Bevilacqua Leoneti; Valquiria Aragão-Leoneti; Simone Vasconcelos Ribeiro Galina; Geciane Silveira Porto
      Pages: 637 - 651
      Abstract: Brazil is considered one of the world’s leading producers of biofuels given the predominance of ethanol fuel in its energy matrix. However, despite the prominence of Brazil in ethanol production, the vast majority of biodiesel production plants in Brazil use methanol instead of ethanol as the alcohol for transesterification reaction, as is generally the case in the rest of the world. The aim of this paper is therefore to examine the transesterification process in the Brazilian biodiesel production in terms of sustainability. In this regard, it was necessary to evaluate the way in which the industrial process is currently carried out, the role of government incentives or subsidies for the use of ethanol to produce biodiesel, and the investments of companies in technology development for the same purpose. This study presents indications that the development of the biodiesel market in Brazil is still oriented toward a production model which is inconsistent with the environmental and social aspects of sustainability.

  • An exploration of the interaction between socio-economic productivity and
           water withdrawal
    • Authors: Souha El Khanji
      Pages: 653 - 677
      Abstract: The term sustainability invites interest in the main factors that affect the deterioration of natural resources. Different hypotheses have been put forward concerning the relationship between water and its effect on different economic sectors. Several questions can be asked here, for example: Does a higher water withdrawal for one sector mean that this sector is adding more to the GDP or is it a sunk cost (it is the cost that should be ignored compared to the benefit of water withdrawal for an individual economic sector) compared with the benefits to the economy? Do social factors affect water withdrawal more than economic factors or are they both impacting equally? We aim to answer these questions and to shed light on different socio-economic factors that affect water withdrawal in different economic sectors. This study investigates, in depth, the interaction between humans and the environment and can be useful in monitoring the direct effect on water withdrawal from agricultural and non-agricultural sectors and on different national economic variables that act as an indicator for economic development and growth. We used simultaneous equation models in our analysis, both the three-stage least squares and the two-stage least squares to explore the relationships. For more credibility, we run the fixed and random effects of 2SLS. Our results showed the influence of trade openness and economic growth on water withdrawal for different economic sectors, and the effect of an increasing demand for water for non-agricultural purposes, which adds pressure on the agricultural sector and eventually may lead to rising food prices.

  • Animal source foods consumed in two fishing communities on the northeast
           coast of Brazil
    • Authors: Marcia Freire Pinto; José Silva Mourão; Rômulo Romeu Nóbrega Alves
      Pages: 679 - 692
      Abstract: Fish are a valuable source of essential micronutrients and animal protein consumed worldwide, especially in coastal regions. However, changes have been observed in eating habits of many fishing communities in Brazil, although this is seldom investigated in the northeast region of the country. Therefore, the aim of this study was to characterize food consumption of meat, especially fish meat, in two fishing communities of Brazilian Northeast. During 2013, information was collected through interviews and food frequency questionnaires regarding eating habits of artisanal fishermen and their families. It was found that fish was the main source of animal protein, although there are differences in consumption according to age and gender of respondents due to dietary restrictions. A difference in the frequency of fish consumption among the communities studied was also found, and there was no correlation between fishermen’s fish preference and fish with higher commercial value. The information obtained is important to understand eating habits of fishing communities, contributing to the development and implementation of public health policies with a focus on food and nutrition security.

  • Climate change, sustainable water management and institutional adaptation
           in rural sub-Saharan Africa
    • Authors: Admire M. Nyamwanza; Krasposy K. Kujinga
      Pages: 693 - 706
      Abstract: Much current work on climate adaptation options vis-à-vis water management in rural sub-Saharan Africa has tended to focus more on technological and infrastructural alternatives and less on institutional alternatives. Yet, vulnerability to climate variability and change in these contexts is a function not just of biophysical outcomes but also of institutional factors that can vary significantly at relatively finer scales. This paper seeks to contribute towards closing this gap by examining institutional options for sustainable water management in rural SSA in the context of climate change and variability. It explores challenges for transforming water-related institutions and puts forward institutional alternatives towards adapting to increasingly complex conditions created by climate change and variability. The paper suggests revisiting the Integrated Water Resources Management approach which has dominated water institutional debates and reforms in Africa over the recent past, towards actively adopting resilience and adaptive management lenses in crafting water institutional development initiatives.

  • Human ecological effects of tropical storms in the coastal area of Ky Anh
           (Ha Tinh, Vietnam)

      Abstract: Vietnam is prone to tropical storms. Climate change effects contribute to sea level rise, floods, progression of the low water line and coastal erosion. This paper inventories the perception of local people, assesses and values main aspects of the livelihood damage caused by the tropical storms of the period 2008–2013 in three coastal communes of the Ky Anh District of the Ha Tinh Province in Central Vietnam. The communes were selected because the location of their coastal line is perpendicular to the storm itself, which made them prone to damage. The effects of increasingly extreme weather conditions on three communities in an area most affected by storms and floods on the local residents and their responses to these changing environmental conditions are analyzed and assessed. The results of questionnaires completed by randomly selected local inhabitants of these communes show that storms and related hazards such as flood, sea level rise and heavy rain are perceived as the most impacting climate change intensified phenomena on agriculture and aquaculture, livestock, household property and income. Opinions and measured data provided by the commune and district authorities allow estimating the total direct cost of the tropical storm at 1.56 million $US (The used conversion rate VND/$US is 21,730 when the research was conducted in 2014) during the period 2008–2013. The long-term costs of adaptation and social impact measures will be significantly higher. Details of the monetary figures allow identifying the physical and natural capital of the area as being most affected by the storm. Trend and cost analysis show that the total financial support for hazard prevention and management during 2014–2019 is estimated at 1.19 up to 1.32 million $US. Local stakeholders indicate that climate change adaptation should not be limited to technical measures such as strengthening dikes, but also should target planting protection forests and mangroves and land use planning. Financial support for the relocation policy, stakeholder involvement and integrating climate change adaptation in both the socioeconomic development master plan and local land use planning are also of importance.

  • Soil conservation practices and production efficiency of smallholder farms
           in Central China
    • Authors: Zhihai Yang; Amin W. Mugera; Ning Yin; Yumeng Wang
      Abstract: The aim of this paper is to evaluate and analyze the impact of adoption of soil conservation practices (SCPs) on the technical efficiency of smallholder rice producers in Central China. We address self-selection bias and unobserved heterogeneity problems by estimating a switching regression model for the adoption decision function and separate stochastic production frontiers for SCP and Conventional farms while allowing for production inefficiency. SCP farms exhibit statistically higher average technical efficiency than Conventional farms. Education, extension services, membership in cooperatives, access to credit, and alternative income sources are positively and significantly associated with technical efficiency for both groups. Conventional farms display higher partial output elasticity for land, while only SCP farms show significant elasticity for capital.

  • Estimation of soil loss and identification of erosion risk zones in a
           forested region in Sarawak, Malaysia, Northern Borneo
    • Authors: H. Vijith; L. W. Seling; D. Dodge-Wan
      Abstract: Soil loss has been quantified and land area categorized for soil erosion vulnerability in a partially forested subwatershed of the Baram River basin (Sarawak, Malaysia) using Revised Universal Soil Loss Equation, which considers climatic and terrain variables. The quantification of soil loss was achieved by integrating the parameters related to rainfall (R), soils (K), terrain (LS) and land use practices (C). The resultant maps of soil erosion show soil losses ranging from 0 to 1190 t ha−1 year−1 with a mean of 28 t ha−1 year−1 in the 1029 km2 Sungai Patah subwatershed study area. The subwatershed was mapped using ArcGIS into five classes of soil erosion risk vulnerability. Among the five classes identified, very high and critically vulnerable zones show linear distribution in some areas which together constitute 13% of the total study area. High and medium erosion vulnerable zones cover 30 and 19%, respectively. Low erosion risk zones cover 36% of the total area. Mean soil loss assessed for each LULC (land use/land cover) class indicates that barren land with high slopes contributes comparatively high rates of soil loss (343 t ha−1 year−1). Field surveys in the study region have enabled identification of erosion hot spots, such as logging areas, shifting cultivation areas and road construction, which intensely modify the terrain, and explain the linearity of critical and severe erosion risk features. The output of the present study will help to frame appropriate management strategies to minimize erosion through implementation of alternative methods in logging activities and terrain management programs.

  • Effects of meteorology on ground-level ozone (GLO) concentrations and
           identifying the hot spots having significantly higher GLO concentration in
           a semi-urban area
    • Authors: A. K. Gorai; S. S. Biswal; Gargi Mitra
      Abstract: The present study aims to analyse the influences of five meteorological parameters (temperature, wind speed, barometric pressure, rainfall, and solar radiations) on ground-level ozone (GLO) concentrations over the region of Ranchi Municipal Corporation (Jharkhand, India). The diurnal variation of GLO concentration and the meteorological parameters were analysed in each month to understand the associations. The results indicated that the correlation coefficients of GLO concentration with SR, AT, and DPT are found to be positive in each month and also statistically significant. But, the association between WS and GLO concentration was not uniform between the study days. Furthermore, the study also demonstrates an approach for identifying the hot spots that are having the higher level of GLO concentration. The hot spot maps were produced for each month to understand the shifting of the locations of hot spot locations. The results reveal that the hot spot locations are changes frequently in each case. Since the hot spot analysis was conducted with limited data, the presented hot spots are indicative and dependent on the meteorological conditions of the specific period and cannot be considered as a robust epidemiological study.

  • An economic-environmental analysis of selected barrier-coating materials
           used in packaging food products: a Swedish case study
    • Authors: G. Venkatesh; Åsa Nyflött; Chris Bonnerup; Magnus Lestelius
      Abstract: The purpose of a barrier coating in food packaging is primarily to increase the shelf life of the foodstuff contained within the packaging, preserve its colour, odour, taste and quality, and thereby reduce food wastage (both at retail outlets and households). While most publications hitherto have compared packaging and barrier-coating materials on the basis of their environmental impacts alone, this paper adopts a more holistic approach by factoring in the economic aspect as well. Four barrier material alternatives—starch, polyethylene, EVOH + kaolin and latex + kaolin are analysed. Two well-defined end-of-life handling scenarios, relevant to Sweden, are: one in which everything except starch is recycled, with starch being composted, and the other in which everything is incinerated. Among the several environmental impact categories which can be analysed, this paper considers only global warming. Two approaches are tested to combine the economic and environmental aspects—normalisation, weighting and aggregating on the one hand, and using the carbon tax to internalise the externality caused by GHG emissions on the other. For the set of weighting factors obtained thanks to a survey conducted by the authors (40.6% for environmental and 59.4% for economic), starch emerges as the most sustainable alternative, followed by polyethylene for both the end-of-life handling scenarios. This tallies with the result obtained by using the carbon tax for internalisation of the externality. The case study, methodology and results presented in this paper, will hopefully be a springboard for more detailed studies of this nature, under the umbrella of sustainability.

  • Sustainability and customers’ hotel choice behaviour: a choice-based
           conjoint analysis approach
    • Authors: Vivek Kumar Verma; Bibhas Chandra
      Abstract: Due to rising environmental concern and awareness amongst consumers, efforts to make hotel operations sustainable are becoming increasingly important. The study here is designed to investigate the contributions of sustainability in consumers’ overall hotel choice decision, particularly which attributes of sustainability is relatively more important amongst others. Data were collected using both qualitative (word association test) and quantitative (orthogonal choice design survey) measures from the sample of 168 and 405 hotel customers, respectively, through purposive sampling technique. The qualitative research identified that customers perceive energy conservation, recycling, and greenscaping as key sustainable practices pertaining to the hotel industry. The findings of choice-based conjoint analysis confirm that sustainability is the most preferred attribute in the hotel choice decision in the present milieu. Moreover, consumers strongly associate greenscaping with the sustainable practices most in the hotel industry. The study significantly contributes to the measurement of sustainability in theory and practice in hospitality and tourism industry.

  • Climate change and food security: a Sri Lankan perspective
    • Authors: Mohamed Esham; Brent Jacobs; Hewage Sunith Rohitha Rosairo; Balde Boubacar Siddighi
      Abstract: There is growing concern in Sri Lanka over the impact of climate change, variability and extreme weather events on food production, food security and livelihoods. The link between climate change and food security has been mostly explored in relation to impacts on crop production or food availability aspects of food security, with little focus on other key dimensions, namely food access and food utilization. This review, based on available literature, adopted a food system approach to gain a wider perspective on food security issues in Sri Lanka. It points to several climate-induced issues posing challenges for food security. These issues include declining agriculture productivity, food loss along supply chains, low livelihood resilience of the rural poor and prevalence of high levels of undernourishment and child malnutrition. Our review suggests that achieving food security necessitates action beyond building climate resilient food production systems to a holistic approach that is able to ensure climate resilience of the entire food system while addressing nutritional concerns arising from impacts of climate change. Therefore, there is a pressing need to work towards a climate-smart agriculture system that will address all dimensions of food security. With the exception of productivity of a few crop species, our review demonstrates the dearth of research into climate change impacts on Sri Lanka’s food system. Further research is required to understand how changes in climate may affect other components of the food system including productivity of a wider range of food crops, livestock and fisheries, and shed light on the causal pathways of climate-induced nutritional insecurity.

      Abstract: Fish is a key source of protein for many households in Ghana. It is also an essential source of income to many households in the coastal communities of Ghana. The importance of the fisheries sector to the socio-economic development of the country cannot be over emphasised. Women dominate the fishing value chain in Ghana but paradoxically, the study of their activities has not attracted the attention of researchers and policy makers. This study examined the processing and sale of smoked marine fish and its effects on the livelihood of women in Mfantseman Municipality. The survey was conducted in four communities. A sample size of 363 was drawn from women in the industry and institutions whose activities are related to the industry. The data were analysed using quantitative and qualitative methods. Findings from the study revealed that the industry offers employment opportunity for the majority of women in the municipality, and it is an important source of income to them. Further, the industry has potentials for reducing poverty and enhancing economic empowerment of women in the district. However, women in the industry are confronted with challenges which include health risks that erode whatever gains made by them. The study concludes that the municipal assembly must spearhead and provide a conducive environment for this economic activity to flourish as a way of reducing poverty among women in the municipality.
