Sustainability in Mexican Higher Education: towards a new academic and professional culture

This article focuses on institutions of higher education and the introduction of sustainability in the curricula of these institutions. It states that a very important part of developing new curricula is the focus on a new academic and professional culture. The key argument is as follows. Normally institutions of higher education build upon the training that students received in previous phases of education. That is why institutions of higher education can focus on education in highly specific and specialized knowledge and skills. Education for sustainability, however, cannot follow this ‘normal’ pathway because much of what students learned in their previous education does not fit into the paradigm of sustainability. That is why sustainability education should include a partial ‘re-education’ and ‘re-programming’ of students. The article presents a framework for such a new academic and professional culture focussing on sustainability. It shows how this framework is developed within the Universidad Autónoma Metropolitana, Unidad Azcapotzalco (UAM-A) in Mexico. The article also shows how the development of this framework is embedded in various initiatives on a national and international level. First of all the framework is developed as part of the design and implementation of an environmental plan for the whole university. The making of this plan is encouraged by the Mexican National Association of Universities and Higher Educations Institutions. Since the year 2002 this Association stimulates all major universities in Mexico to develop and implement such an environmental plan. These activities on their turn fit very well into the “United Nations Decade of Education for Sustainable Development” that started in January 2005. Finally the article presents the first promising results of the new course “The environmental challenges” that is based on many elements of the framework. It was started in 2005 in the Division of Basic Sciences and Engineering of UAM-Azcapotzalco, Mexico.     

Environmental education: new paradigms and engineering syllabus

The issue of sustainability places particular demands on engineers to become more ‘connoisseur’ of the roots of the problems, in addition to being ‘trained’ in problem solution techniques that emphasize holistic approaches (for both the social and ecological environment). We have introduced the new E3 model, as outlined here, to chemical engineering students, with an integrated approach to translate ‘generic’ common-sense pollution prevention strategies (design, operation) into definite problems where engineering science can be put into action. New tools (such as minimization hierarchy and life cycle), as well as abilities both to identify and evaluate environmental problems, and to propose, select and implement solutions, provide methods for understanding a problem and for mitigating it through (re)design of a product or process, by emphasizing basic approaches to analysis, synthesis and integration. Additionally, control technologies can be systematized, including the best available selection procedures on which the emission limits are based. Awareness, institutional factors and normative-ethical aspects are also considered.     

Eco-design in innovation driven companies: perception, predictions and the main drivers of integration. The Spanish example

This study attempts to contribute to the scarce knowledge on how eco-design, and to broad extent sustainability, is connected to innovation driven companies. In particular, this cross sectional research verifies i) perception and knowledge of eco-design of the professionals from innovation driven companies in Spain, ii) specific eco-design strategies towards sustainability that innovation driven companies are integrating in their strategic plans and their application in the supply chain and iii) the companies’ future predictions on innovation and eco-design linkage. The methodology of this paper is based on a survey, developed defining measurable proxies for both eco-design and innovation approaches and conducted on 10,000 multidisciplinary professionals from Spanish innovation driven companies. The study shows that sustainability is a cardinal driver for innovation and that responses have specificities regarding company size, activity or respondent position. Innovation and eco-design strategies for the future aim to use materials with a lower environmental impact and to develop new concepts.     

Teaching sustainability as a contested concept: capitalizing on variation in engineering educators' conceptions of environmental,social and economic sustainability

This study documents variation in engineering academics conceptions of sustainability. We investigated how a group of Australian engineering academics described environmental, social and economic sustainability, and identified a broad range of actions that participating academics associated with achieving sustainability. The study suggested marked variation in the actions that participating academics viewed as coherent with sustainable engineering practice, and therefore, potentially marked variations in the sustainability actions academics might advocate to their undergraduate students. Rather than framing this variation as problematic for teaching and learning sustainable engineering, we suggest that such variation in conception of sustainability, and explicit contestation of this variation in the engineering classroom, offers opportunities to enrich undergraduate sustainability learning and teaching. We develop this argument by using some generic environmental, economic, and social theoretical frameworks to characterize the differences according to the values and assumptions that may underpin the observed variation. Validated frameworks are useful to move beyond discussions based on ‘opinion’, because they provide a framework for critical reflection by engineering students and academics about the values and assumptions that inform engineering practice generally and sustainable engineering practice, particularly.     

Towards phosphorus sustainability in North America: A model for transformational change

Global food production and security rely heavily on finite reserves of newly mined phosphate for fertilizers. However, systemic inefficiencies result in the deposition in aquatic ecosystems of much of the phosphorus mined for food production causing costly eutrophication problems that damage aquatic ecosystems and human health. The Sustainable Phosphorus Alliance (SPA, formerly named North American Partnership for Phosphorus Sustainability) was created to implement sustainable phosphorus solutions through active engagement of stakeholders in both the private and public sectors. This paper describes a conceptual model of transformative change to a sustainable phosphorus system for the North American region. The model emerged from discussions at a series of formal and informal meetings held in conjunction with a ‘Future of Phosphorus’ event (National Science Foundation’s Phosphorus Sustainability Research Coordination Network) and an inaugural SPA Board meeting. Model development drew on the multi-level perspective of socio-technical transitions to develop a series of pathways to a transformed phosphorus system. The uses of the model and transition pathways are discussed in terms of their potential to form an important first step towards the development of a regional vision for improved phosphorus sustainability. The process provides an example of how research in sustainability science can contribute to action on environmental improvement.     

Transdisciplinary sustainability research beyond engagement models: Toward adventures in relevance

Transdisciplinary models of research are increasingly upheld as the gold standard of collaborative science to solve complex social and environmental problems, promising to ‘close the gap’ between knowledge and action, inject science with greater accountability, democratic participation, and include stakeholders as practitioners of research. Absent in transdisciplinary models are more ‘risky’ questions of relevance, subject positionality, and the lived encounters between researchers and stakeholders. Who are the ‘holders’ and who determines the ‘stakes’? This article examines how notions of roles, typologies, and effectiveness constrain relationships between researchers and stakeholders; and document the ways in which research teams, shot through with these tensions, in turn develop new roles, typologies, and markers of ‘success’. In drawing on recent philosophical scholarship on social science practices, we argue that relevance in transdisciplinary research cannot rest on typologies, logics, and templates of collaboration in which effectiveness is determined in advance. The growing business of team science and its predictive aspirations risk rendering transdisciplinary research irrelevant if its practitioners do not loosen the grip on realist perspectives on stakeholder roles, research outcomes, and metrics of success. Instead, we argue for the development of skills for paying attention to the categories, friction, and tensions that are provoked by collaborative interactions, discourses, and techniques with stakeholders. Environmental researchers must learn to be responsive to the durable existence of stakeholders and seek to develop the means to reveal what matters, and therefore is relevant, to them.     

An approach to scenario analysis of the sustainability of an industrial sector applied to clothing and textiles in the UK

Companies aiming to be ‘sustainability leaders’ in their sector and governments wanting to support their ambitions need a means to assess the changes required to make a significant difference in the impact of their whole sector. Previous work on scenario analysis/scenario planning demonstrates extensive developments and applications, but as yet few attempts to integrate the ‘triple bottom line’ concerns of sustainability into scenario planning exercises. This paper, therefore, presents a methodology for scenario analysis of large change to an entire sector. The approach includes calculation of a ‘triple bottom line graphic equaliser’ to allow exploration and evaluation of the trade-offs between economic, environmental and social impacts. The methodology is applied to the UK's clothing and textiles sector, and results from the study of the sector are summarised. In reflecting on the specific study, some suggestions are made about future application of a similar methodology, including a template of candidate solutions that may lead to significant reduction in impacts.     

Sustainability assessment of a farm in the Chianti area (Italy)

In the study of agricultural systems, where land fertility and environmental conditions are primary factors, it is essential to consider both the efficiency and the environmental sustainability of processes. Emergy analysis, introduced by H.T. Odum [Science 242 (1988) 1132], is an approach developed at the interface between thermodynamics systems ecology. It was here used to obtain sustainability indicators and to assess the efficiency of a complex agricultural system, a farm in the Chianti area.The results for different crops were compared with Italian averages to obtain an idea of the long-term sustainability of this agricultural system. The cultivation of all the crops on the farm, except grapes, was more efficient and had less impact on the environment than the Italian standards. The Chianti grapes were compared not only with the Italian average but also with grapes of similar high quality, ‘Brunello di Montalcino’ and ‘Nobile di Montepulciano’, both grown in the same region. The production of grapes in the Chianti vineyard was more efficient and had an intermediate environmental impact, in the emergy sense, with respect to the other two systems.The proportion of emergy inputs to the farm that are local or renewable is quite high. Thus the emergy analysis demonstrated that the Chianti farm has a relatively good long-term sustainability considering both the whole system, and its individual crops.     

Sustainable development and the water–energy–food nexus: A perspective on livelihoods

The water–energy–food nexus is being promoted as a conceptual tool for achieving sustainable development. Frameworks for implementing nexus thinking, however, have failed to explicitly or adequately incorporate sustainable livelihoods perspectives. This is counterintuitive given that livelihoods are key to achieving sustainable development. In this paper we present a critical review of nexus approaches and identify potential linkages with sustainable livelihoods theory and practice, to deepen our understanding of the interrelated dynamics between human populations and the natural environment. Building upon this review, we explore the concept of ‘environmental livelihood security’ – which encompasses a balance between natural resource supply and human demand on the environment to promote sustainability – and develop an integrated nexus-livelihoods framework for examining the environmental livelihood security of a system. The outcome is an integrated framework with the capacity to measure and monitor environmental livelihood security of whole systems by accounting for the water, energy and food requisites for livelihoods at multiple spatial scales and institutional levels. We anticipate this holistic approach will not only provide a significant contribution to achieving national and regional sustainable development targets, but will also be effective for promoting equity amongst individuals and communities in local and global development agendas.     

An integrated approach to achieving campus sustainability: assessment of the current campus environmental management practices

Universities can nowadays be regarded as ‘small cities’ due to their large size, population, and the various complex activities taking place in campuses, which have some serious direct and indirect impacts on the environment. The environmental pollution and degradation caused by universities in form of energy and material consumption via activities and operations in teaching and research, provision of support services and in residential areas could be considerably reduced by an effective choice of organizational and technical measures. Although many environmental protection measures can be seen at some universities, but a more systematic and sustainable approach to reducing the negative impacts of those activities and making the campuses more sustainable, is generally lacking. Therefore, this paper proposes a framework of a more suitable approach to achieving campus sustainability that could remedy the limitations of the current environmental management practices in universities and ensures more sustainability through the integration of three strategies, namely: university Environmental Management System (EMS); public participation and social responsibility; and promoting sustainability in teaching and research.     

Games by which to learn and teach about sustainable development: exploring the relevance of games and experiential learning for sustainability

This paper discusses the roles of games in experiential learning for sustainability. It includes applied emphases upon four topics: (1) The challenges of sustainable development education with the need for interdisciplinarity, knowledge, skills and attitudinal training and with a special focus upon the urgent needs for paradigm, context and practice changes to help ensure that we make progress toward sustainable societies. We emphasize that these characteristics challenge existing teaching and educational philosophies and methods. (2) The theory of experiential learning, as developed by David Kolb in the nineteen eighties. We underscore that experiential learning is a good model for education for sustainability. (3) The usefulness of games as tools in learning processes. Various aspects of games are discussed such as the ‘functions of games’ and ‘the different categories of games,’ and ‘the role of games in learning and particular in experiential learning.’ These three aspects form the theoretical part of the paper. (4) Brief reviews of some illustrative games. The authors provide practical advice on how to play games in the context of learning for SD. They underscore facets such as the contextualization of games, technical aspects of playing games and the debriefing after the games have been played. The authors conclude the paper with conclusions that games are potentially relevant in all of the four learning phases of experiential learning. Games are especially relevant in phase four. In this phase games can contribute to helping learners to effect shifts in their personal paradigms, context and practice that are needed for sustainable development. The final conclusion is that many games exist and have been proven to be helpful. Educators are invited to change their curricula to facilitate usage of games as integral components of their educational philosophy tools and practice.     

Top-down and Europe-wide versus bottom-up and intra-regional identification of key issues for sustainability impact assessment

Sustainability impact assessment tools aim at optimising the development of policy measures. Here, we present an approach to designing policies for multifunctional land use with application to Europe and its regions. After the 35 environmental, social and economic impact issues of the European Impact Assessment Guidelines were reviewed on the basis of spatiotemporal indicators at both the top-down Europe-wide and bottom-up intra-regional resolution level, cluster analysis identified classes with specific sustainability characteristics and thus regions most likely facing similar sustainability problems. Sensitive region types such as post-industrial zones, mountains, coasts and islands were analysed separately. The results of the cluster analysis were tested against evidence-based information such as UNEP priorities and regional stakeholder evidence. Stakeholder evidence was specifically explored for the land use policy ‘bioenergy promotion’ in Lusatia, Germany. We concluded that these top-down and bottom-up spatiotemporal data classifications with cluster analysis represent useful ex-ante impact assessment tools and need to be supplemented by participatory assessments. This procedure with top-down and bottom-up data analysis, and also participatory evidence, provide a valuable three-step sustainability impact assessment approach in policy making.     

Considering agro-ecosystems as ecological funds for collective design: New perspectives for environmental policy

Enhancing agro-ecosystem sustainability raises difficult challenges for environmental policy: it requires both increasing knowledge on these complex systems to design effective solutions and coordinating stakeholders with diverging interests. However, most existing environmental policies consider ecosystems’ desirable properties as given, leading ecosystem managers to favor “turnkey” solutions. How could public policy better support local collective initiatives aiming at reconciling agriculture and the environment? This paper presents an empirical case study from western France, in which a partnership between an agricultural cooperative and an ecological research center resulted in a collective design initiative. We conceptually model this initiative drawing upon recent design theories and Georgescu-Roegen’s ‘fund-flow’ model, defining ‘ecological funds’ as the starting point of a collective design process. The results highlight the importance of developing policy instruments that can better support local innovation processes through greater democratization. Adopting a design approach to sustainable agricultural landscape management could be particularly fruitful in situations where collective action is necessary but where there is no common good recognized as such, and no existing community identified.     

Socio-economic factors in soil erosion and conservation

Farmer decisions with regard to production and land use are strongly influenced by socio-economic factors. In the developed world, the role of agricultural subsidies, quotas and guaranteed prices is especially important. In the past there have been many examples of economic signals which led to unfortunate and unforeseen environmental consequences (‘perverse subsidies’), including soil erosion. The problems were neglected because of an emphasis on increases in productivity and the fact that many of the costs were hidden or were external to the farm and were borne by society. In recent years ‘agri-environmental measures’ have begun to reverse the trend towards environmental degradation.     

Corporate social responsibility in the mining industry: Exploring trends in social and environmental disclosure

In recent years, concerns about the sustainability and social responsibility (CSR) of businesses have become an increasingly high profile issue in many countries and industries, none more so than the mining industry. For mining, one outcome of the CSR agenda is the increasing need for individual companies to justify their existence and document their performance through the disclosure of social and environmental information. This paper explores recent trends in the reporting of such impacts and issues in the global mining industry. It offers a detailed review of the development of the media of social and environmental disclosure in the mining industry, and of the factors that drive the development of such disclosure. A temporal analysis of the recent trends in disclosure using a case study of the world's 10 largest mining companies is presented. Whilst there is evidence of increasing sophistication in the development of social and environmental disclosure, there is considerable variation in the maturity of reporting content and styles of these companies. The paper offers a simple classification of reporting companies, from ‘leaders’ to ‘laggards’. Stronger leadership and co-operation from the top reporting companies is necessary to support the laggards of the industry.     

From green product definitions and classifications to the Green Option Matrix

Hybrid cars, recycled products, photovoltaic cells, bioplastics: why so different products can be called ‘green’? Which practices companies willing to develop green products should implement? How companies can easily and effectively communicate to stakeholders the environmental features of their green products? This paper tries to answer these questions, by developing a Green Option Matrix (GOM), which characterizes green products and practices along different dimensions. This matrix is then used to analyze the different features of green products as well as related green practices developed by a sample of companies belonging to the Dow Jones Sustainability World Index (DJSWI). Relevant data are collected by means of content analysis of companies’ websites and sustainability reports. Green products and practices developed by each company in the sample are positioned in the matrix and results are presented and discussed for each industrial sector. Then, different sectors’ behaviors are compared. The proposed matrix can be used by companies as a market tool to analyze competitors’ green products and practices and as a communication tool to effectively communicate to stakeholders the specific green features of their products and practices.     

Domestic or imported? An assessment of carbon footprints and sustainability of seafood consumed in Australia

The distance between where food is produced and consumed is increasing, and is often taken as evidence of an unsustainable global food system. Seafood is a highly traded commodity yet seafood sustainability assessments do not typically consider the impacts of the movement of products beyond the fishery or farm. Here we use life cycle assessment to examine the carbon footprint of the production and distribution of select seafood products that are consumed in Australia and determine differences in the sustainability of imports and their domestically produced counterparts. We found that the distance food is transported is not the main determinant of food sustainability. Despite the increased distance between production and consumption, carbon footprints of meals from imported seafood are similar to meals consisting of domestically produced seafood, and sometimes lower, depending on the seafood consumed. In combining LCA with existing seafood sustainability criteria the trade-offs between sustainability targets become more apparent. Carbon ‘footprinting’ is one metric that can be incorporated in assessments of sustainability, thereby demonstrating a broader perspective of the environmental cost of food production and consumption.     

The natural advantage of regions: linking sustainability,innovation, and regional development in Australia

The combined impacts of the financial crisis and climate change are driving the evolution of sustainable business and changing the way that governments plan for development. Markets are emerging for a range of environmentally orientated products and services as societies move (or lurch) towards reducing impacts and adapt to changing conditions. National governments are actively formulating policy and providing investment to develop green economies as one of the responses to the global financial crisis. Many of the political and economic drivers have been focused at the international and national scale, and while critical for setting the national framework for development, it often neglects the key role that regions and localities can play in ecological modernization. This paper explores two regional case studies in New South Wales (NSW), Australia, that are initiating shifts towards networks of sustainable businesses and communities and offers recommendations for further policy development. The focus of this paper is on the evolving regional sustainability market and its relationship to other social institutions including governments, communities and the individual. The unifying concept is the idea of the ‘natural advantage’, a model that integrates innovation and sustainability as a part of the regional development policy agenda.     

Anatomy of a buzzword: The emergence of ‘the water-energy-food nexus’ in UK natural resource debates

The existence of a water-energy-food ‘nexus’ has been gaining significant attention in international natural resource policy debates in recent years. We argue the term ‘nexus’ can be currently seen as a buzzword: a term whose power derives from a combination of ambiguous meaning and strong normative resonance. We explore the ways in which the nexus terminology is emerging and being mobilised by different stakeholders in natural resource debates in the UK context. We suggest that in the UK the mobilisation of the nexus terminology can best be understood as symptomatic of broader global science-policy trends, including an increasing emphasis on integration as an ideal; an emphasis on technical solutions to environmental problems; achievement of efficiency gains and ‘win-wins’; and a preference for technocratic forms of environmental managerialism. We identify and critique an ‘integrative imaginary’ underpinning much of the UK discourse around the concept of the nexus, and argue that attending to questions of power is a crucial but often underplayed aspect of proposed integration. We argue that while current efforts to institutionalise the language of the nexus as a conceptual framework for research in the UK may provide a welcome opportunity for new forms of transdisciplinary, they may risk turning nexus into a ‘matter of fact’ where it should remain a ‘matter of concern’. In this vein, we indicate the importance of critique to the development of nexus research.     

On properties of linear programming model for acid rain abatement

For linear programming problems arising in the field of acid rain abatement (in the case of a linear source-receptor relationship and linear or piecewise-linear abatement cost functions) the following properties are established.In the optimal solution, the number of sources which are not at an ‘inflection point’ of the corresponding piecewise-linear cost function is equal to the number of binding environmental constraints. (Here ‘inflection point’ denotes a point where the piecewise-linear cost function changes its slope; an environmental constrainst is called ‘binding’ if, for the optimal solution, the calculated deposition is just equal to, and not less than, the constraint.) As a consequences, several (i.e. the remaining) sources have optimum emissions which ‘get stuck’ at an inflection point. This influences the results of sensitivity analyses as well as the numerical accuracy of the optimal solution (if the piecewise-linear cost function has been obtained as a coarse approximation to a more complicated cost function).Moreover, for targets becoming more stringent, the optimum abatement costs may decrease for certain sources, although the total abatement costs increase, of course. This rather unexpected effect indicates that ‘pure’ optimization results should be applied, e.g. in negotiations, in a careful manner.
