Promoting Sustainability with Ecological,Economic and Social Dimensions in Developing Countries

Abstract

Sustainable development is one of the most important ideas, and goals of our time. It is defined as “development which meets the needs and aspirations of the current generation and develops safe and sound society for future generation”. Achieving sustainable development thus involves a vigorous and urgent debate on different dimensions. The different dimensions of sustainability as a framework involve all issues such as science, technology, economic growth and development, health, education, finance investment and trade, politics, natural disasters, population growth and terrorism, etc. No single dimension is responsible to develop sustainable society. This article mainly described the integrated relationship among the three dimensions of sustainability.

Negotiating Virtue and Vice: Articulations of Lay Conceptions of Health and Sustainability in Social Media Conversations around Natural Beverages

Prior studies have suggested that despite increasing sustainability awareness, many consumers are confused about the impact of green products on their health and the environment. Unlike those studies that privilege professional discourse and adopt unrealistic presumptions of rationality and morality, this article showcases consumers as active co-producers of value and meanings. Using netnography, it analyzes social media conversations around Naked Juice and Innocent smoothies—two products marketed as healthy, all-natural, and environmentally sustainable beverages. The findings reveal a baseline picture of the products' virtues of healthiness feeling (hedonic) and holistic health image (symbolic). The article illustrates how this moral conception was dynamically constructed and transformed in the course of consumers' communicative practices. It proposes three discursive strategies by which consumers negotiate the nature and boundaries of good and bad choices vis-à-vis the products: highlighting (separating virtue from vice), balancing (reconciling virtue and vice), and resisting (reconstructing virtue as vice).     

Good Food,Good Intentions: Where Pro-sustainability Arguments Get Stale in US Food Documentaries

Focusing on recent documentaries about sustainable agriculture in the US—Food, Inc., The Garden, Fresh, and Farmageddon—this paper examines how pro-sustainable food arguments fail to merge environmentalism and environmental justice. By framing their approach to sustainable food production around the normative issue of “good food” for capitalist consumers, such documentaries ignore questions about community and cultural conceptions of farmers. In the process the films promote a problematic vision of the white family farm. As a consequence, these films limit a reimagining of alternative food systems, the roles for diverse actors within those systems, and possibilities for eaters beyond “voting with your fork.” Several exceptions, most notably The Garden, are used to suggest how cinema might radically re-envision participation in alternative forms of agriculture.     

Sustainability classifications in engineering: discipline and approach

In order to discuss how to advance sustainability in engineering, it is necessary to be clear as to what exactly is the science of sustainability. The linkage between sustainability philosophy and scientific principles has, in some ways, been acknowledged in the wider literature. Moreover, the recent scholarship on sustainability in international literature has focused on providing definitions, policies and methods, though from an engineering perspective, there is an obvious need for clarity on how the engineering and science community can integrate the science of sustainability into practice. Prima facie, this article provides an overview of the development of sustainability science through a textual analysis to collate the underlying discourse and ideology cited in literature. While the number one sustainability challenge is to mitigate climate change, compiling a definition genesis of sustainability will assist the engineering community in gaining an understanding in the underlying philosophical frames. The aim of this paper is to analyse sustainability information in the print press, journals, periodicals and textbooks since publication patterns contribute to our understanding of the cognitive aspects of scholarly knowledge development.     

Towards practice-oriented design for sustainability: the compatibility with selected design fields

Design scholars are currently exploring the potential role of design in fostering sustainable consumption. The social practice has been put forward as a relevant unit of analysis for capturing the dynamics of consumption, and, as a possible unit of intervention for design. This article sets out to explore the extent to which existing design resources may come to use in the development of practice-oriented design. To do that, it takes social practice theory as a starting point, and outlines some implications for design. Based on that, their compatibility with key principles and approaches from the design fields concerned with environmental issues and the relationships between humans and technologies is discussed, and tensions and promising resources are identified. By doing that, the aim is to contribute to the ongoing inquiry into what practice-oriented design may be, and more specifically, to discussions on the characteristics of design and innovation activities that may help foster transitions in less environmentally impacting directions.     

How to encourage conflict in the environmental decision-making process: imparting lessons from civic environmentalism to local policy-makers

The literature on civic environmentalism suggests that the environmental decision-making process must be perceived by citizens to be inclusive, transparent, and legitimate in order to avoid conflict and encourage stakeholder collaboration. We suggest that studies of environmental decision-making must apply this framework to three key variables: agenda setting, conflicts of interest, and politicised institutions, which impact the potential for citizen collaboration at the local level. Using content analysis of newspaper articles, participant observations, and informal field interviews, we evaluate a case study of citizen opposition to a power plant air permit. We demonstrate how citizen perceptions of agenda setting by local officials, conflicts of interest, and the inability of citizens to affect final decisions after winning in multiple legal and administrative venues, creates conflict by not embodying these civic environmentalist principles. We conclude with policy suggestions for creating a less conflict-riddled process.     

Social sustainability – society at the intersection of development and maintenance

Since the late 1980s, much of the debate on sustainability has been dominated by ecological perspectives. However, the last decade has seen an increasing interest in the social aspects of sustainability. While, to some extent, general consensus has been reached regarding the definitions of ecological sustainability, the definition of social sustainability is still in the making. Therefore, there is a need for conceptual frameworks and theoretical constructs in order to develop the understanding of social sustainability further. This article addresses the lack of theorisation and is composed of three different sections. The first section is a literature overview covering some of the most influential texts on social sustainability. The second section introduces and relates a number of existing, polemically constructed theoretical frameworks. In the third section, Jacques Derrida's theory of différance is used to suggest a way of understanding the relationship between the oppositional positions identified in the frameworks.     

Understanding the role and influence of social norms: lessons for NRM

Much has been written about social norms in disciplines such as law and economics but they are less studied in the field of Natural Resource Management (NRM). Although norms are acknowledged to be an influence on decision–making, they are difficult to identify and measure in the field and their role is often implicit or not well understood or articulated. This paper addresses an important knowledge gap by combining social norms theory with the specifics of a particular case study. We examined the influence of social norms on landholder behaviour in a small rural community undergoing demographic change in Australia. Findings from interviews with landholders and government agency personnel indicate that established norms within the farming community are influencing incoming landholders; and that new norms and practices have also emerged as a result of government investment through the local Landcare group. We suggest that a better understanding of social norms in different contexts will give rise to strategies that make NRM interventions more effective.
