A roadmap to a green chemical industry in Australia

A ‘roadmap’ has been devised for a progressive greening of the Australian chemical industry over the next two decades. The roadmap is based on a set of interactive principles broadly termed ‘economic’, ‘social’, ‘technological’, ‘environmental’ and ‘political’, which collectively form the ‘drivers of change’ in chemical industry strategy/business/policy planning—leading to greater efficiency and economic sustainability of this industry. The proposed roadmap pre-supposes that real economic, societal and environmental benefits can be obtained through greater use of existing and emerging green chemical technology. It can play an important role in developing a sustainable chemical industry in Australia. Primarily, the proposed roadmap involves a paradigm shift of the business operating plan and a significant mindset change of management.     

‘Eco-city’ to ‘disaster-resilient eco-community’: a concerted approach in the coastal city of Puri, India

The need for environmental and urban planning reached a critical point in the year 2007, when one-half of the world's population could be defined as living in cities. Urbanisation in India is also increasing at a fast rate. Urban chaos in India, emanating from the continuous ignorance of fragile ecosystems, calls for the reshaping of existing cities as ‘eco-cities’. The ‘eco-city’—a well-known concept in the western world—is new to the Indian context. While western connotations of eco-cities should not be discarded outright in the context of India, core concerns vary significantly for obvious reasons. Recognising two facts—firstly, eco-city development is altogether a fresh approach to human settlement development in India, and, secondly, the manifold increase in the vulnerability of cities—this paper discusses documented good practice, reinforcing evolution towards the eco-city vision. Lessons drawn from the examples cited are further deconstructed in the light of their contribution to urban risk reduction, which provides direction to appreciating the ‘disaster-resilient eco-community’ concept in Puri, a coastal city in India. Further, this paper attempts to unravel existing community-based practices in Puri, which are boon to the local environment and invariably reduce disaster risk. These seemingly modest neighbourhood initiatives symbolise immense societal wealth, which can be calibrated appropriately for reducing urban environmental risk as well. This paper also illustrates how a ‘disaster resilient eco-community’ approach is inevitable in the present and future contexts not only to preserve sustainable development gains but also to secure human well-being.     

Human–environment interactions: learning from the past

The analysis of palaeoenvironmental archives—sediments, archaeological remains, tree-rings, documents and instrumental records—is presented as a key element in the global scientific endeavour aimed at understanding human–environment interactions at the present day and in the future. The paper explains the need for the focus on palaeoenvironmental studies as a means of ‘learning from the past’, and presents the rationale and structure of the IGBP-PAGES Focus 5 programme ‘Past Ecosystem Processes and Human–Environment Interactions’. The past, as described through palaeoenvironmental studies, can yield information about pre-impact states, trajectories of recent change, causation, complex system behaviour, and provide the basis for developing and testing simulation models. Learning from the past in each of these epistemological categories is exemplified with published case-studies.     

A new approach to quantifying and comparing vulnerability to drought

In this study we develop an “inference modeling” approach to compare and analyze how different disciplines (economics, political science, and behavioral science/environmental psychology) estimate vulnerability to drought. It is thought that a better understanding of these differences can lead to a synthesis of insights from the different disciplines and eventually to more comprehensive assessments of vulnerability. The new methodology consists of (1) developing inference models whose variables and assertions incorporate qualitative knowledge about vulnerability, (2) converting qualitative model variables into quantitative indicators by using fuzzy set theory, (3) collecting data on the values of the indicators from case study regions, (4) inputting the regional data to the models and computing quantitative values for susceptibility. The methodology was applied to three case study regions (in India, Portugal and Russia) having a range of socio-economic and water stress conditions. In some cases the estimates of susceptibility were surprisingly similar, in others not, depending on the factors included in the disciplinary models and their relative weights. A new approach was also taken to testing vulnerability parameters by comparing estimated water stress against a data set of drought occurrences based on media analysis. The new methodologies developed in this paper provide a consistent basis for comparing differences between disciplinary perspectives, and for identifying the importance of the differences.

Conceptualising climate change in rural Australia: community perceptions, attitudes and (in)actions

Public engagement and support is essential for ensuring adaptation to climate change. The first step in achieving engagement is documenting how the general public currently perceive and understand climate change issues, specifically the importance they place on this global problem and identifying any unique challenges for individual communities. For rural communities, which rely heavily on local agriculture industries, climate change brings both potential impacts and opportunities. Yet, to date, our knowledge about how rural residents conceptualise climate change is limited. Thus, this research explores how the broader rural community—not only farmers—conceptualises climate change and responsive activities, focussing on documenting the understandings and risk perceptions of local residents from two small Australian rural communities. Twenty-three semi-structured interviews were conducted in communities in the Eden/Gippsland region on the border of New South Wales and Victoria and the north-east of Tasmania. There are conflicting views on how climate change is conceptualised, the degree of concern and need for action, the role of local industry, who will ‘win’ and ‘lose’, and the willingness of rural communities to adapt. In particular, residents who believed in anthropogenic or human-induced factors described the changing climate as evidence of ‘climate change’, whereas those who were more sceptical termed it ‘weather variability’, suggesting that there is a divide in rural Australia that, unless urgently addressed, will hinder local and national policy responses to this global issue. Engaging these communities in the twenty-first-century climate change debate will require a significant change in terminology and communication strategies.     

Role of religious communities in enhancing transition experiments: a localised strategy for sustainable solid waste management in Malaysia

Religion in its most ideal form is seen as a powerful force to create ecological transformations to succeeding generations that share similar religious beliefs. This provides an interesting argument for enhancing their role in sustainability transitions. Malaysia is a relevant geographical context in this regard since almost all of its citizens formally embrace some kind of religious belief. However, such ideas are discussed mostly at the theoretical level with little systematic empirical investigation. This paper aims to fill this gap by presenting theoretically informed empirical insights on how a number of religious communities are currently creating successful experiments in recycling within the context of an urban community in Malaysia. The paper argues that such evidence may demonstrate the ‘potential’ role of religious communities to provide localised resources for recycling experiments that can be advantageous for the transition towards a more sustainable municipal solid waste management in Malaysia. The empirical basis of this paper is based on an exploratory multiple case study of successful recycling programmes conducted by selected religious communities from four key religions in Malaysia—Buddhism, Christianity, Hinduism and Islam. The theoretical framework for this research is based on the sustainability transitions literature, particularly the ‘transition experiment’ framework.     

Sustainability issues for biodiversity business

Biodiversity is acknowledged as one of the most important resources that helps to sustain life’s processes. Additionally, it is also one of the most important sources of livelihood for different kinds of stakeholders at various levels of resource markets—local, domestic, or international. With globalization and increasing sophistication in the methods of commercial trade in biological resources, various issues arise related to the sustenance of resources, of ecological balances, and equity in transactions. All of these are concerns to be addressed to achieve a state of ‘sustainability.’ This paper prescribes to the definition of ‘sustainability’ as the capacity to maintain a certain process or state for “improving the quality of human life while living within the carrying capacity of supporting eco-systems” (IUCN/UNEP/WWF, in Caring for the Earth: a strategy for sustainable living. Gland, Switzerland, 1991). This goes beyond ensuring inter- and intragenerational equity in access to resources and includes several other parameters, including equity among stakeholders to returns from biological resources, related knowledge, trade-offs, and ethical business practices related to these resources. Through the prism of an examination of a simplistic supply route(s) and value addition chain of biodiversity resources for commercial use, this paper reviews and highlights issues related to ‘sustainability’ at each stage. Evidence points to shortcomings in the sustainable use of biological resources at each stage of value addition, calling for focused and specific measures to address them.     

Conservation of Sarawak peat swamp in an urban landscape by fuzzy inference system

Freshwater habitats are one of the planet’s most important, yet most manipulated, environments. This is what happens in Sarawak that the environment has been radically changed due to urban developments. This paper is promoting the idea that we do not need a complicated but a simple tool like fuzzy inference system to strike a balance between the existence of peat swamp and the humans who live nearer and nearer to it. Conditions vital to the survival and continuity of a natural wetland system can be adapted as fuzzy rules. These rules are capable of providing indicators of how much wetland can be exploited and at the same time still allow the system to properly functioning as a wetland.     

Using critical systems thinking to foster an integrated approach to sustainability: a proposal for development practitioners

Throughout the development sector, there is increasing recognition of links between the environment and aspects of development such as poverty alleviation, health, income generation, and agriculture. While furnished with a diverse range of perspectives and approaches, development practice is in need of ways to better conceptualize the interactions between the social, environmental, and economic dimensions of sustainability so that opportunities for simultaneous improvement in human and ecological well-being can be identified more readily. Critical systems thinking is proposed as a way for development practitioners to conceptualize and act toward the integration of these economic, social, and environmental dimensions and, in so doing, support communities to nurture both human and ecosystem well-being. Four desirable attributes of a critical systems thinking approach to development are identified based on development literature, critical systems literature, and the author’s research into sustainability in semi-rural communities in Vietnam. The four attributes are ‘a systems thinking approach;’ ‘an ethical base to action and choices;’ ‘critical reflection permeates processes;’ and ‘appreciation of diverse views and application of diverse approaches.’ These attributes are described and then offered as the basis for further discussion of the ways in which simultaneous improvement of human well-being and ecosystem health can become an integral part of development practice.     

Public disclosures: using information to reduce pollution in developing countries

The failure of formal regulation and market-based approaches to control pollution has highlighted the significance of informal regulation in the form of ‘public disclosure’ and ‘rating’ for achieving environmental goals in the nineties. In developing countries where pollution information is often scarce, disclosure can make a firm’s emissions more costly. This is because it increases penalties from regulators, local communities, consumer organizations and factor markets. Public or information disclosure combines conventional environmental monitoring, self-regulation and public pressure using environmental ratings to promote better environmental management. Thus, it forms an effective tool to control pollution in developing countries like India, China or Kenya and countries-in-transition like Poland, Russia, etc. The different examples given in the paper indicate that effective public disclosure requires a credible scheme with scrutiny at different checkpoints similar to the one used for PROPER in Indonesia or GRP in India.     

Towards better water governance in river basins: some lessons learned from the Volga

This article focuses on the problems of water governance at a river basin level, and on the role of institutional coordination, participation and partnerships between multiple stakeholders towards sustainable water management. Its approach presupposes that institutional capacity building, strengthening coordination between government institutions (vertical and horizontal), on the one hand, and broadening participation and consolidating partnerships between public, private and civil society actors, on the other hand, is among effective tools in integrated water resource management in river basins. It explores environmental challenges, problems, emerging trends and recent institutional innovations in the Volga basin in Russia—the largest river basin in Europe. Transfer and adaptation of good practices in good water governance between the EU and Russia are discussed. This article presents some research findings and lessons learned from practice by the EC international project ‘CABRI—Cooperation along a big river: Institutional coordination among stakeholders for environmental risk management in the Volga basin’, which is assessed as one of the selected success stories of the European research.’     

Assessing the susceptibility of societies to droughts: a political science perspective

In this article we develop a concept for the assessment of state’s susceptibility to drought based on a political science perspective. Different sources of capacities and sensitivities need to be taken into account to assess the overall susceptibility of states as political systems. We argue that the overall susceptibility of a society depends on an interplay of state capacity and readiness as main elements of political susceptibility, wealth and economic sensitivity as elements of economic susceptibility and the degree of social integration. To transform the conceptual model into a susceptibility assessment we developed an inference model in order to generate quantitative indices. For this purpose we apply fuzzy set theory using data from our case study regions, namely Andhra Pradesh (India), the Volga region (Russia) and (Southern) Portugal. The resulting computed trends for Portugal suggest that the society will be able to deal even with severe natural conditions due to existing political, economic, and social conditions. The assessment results for the Indian and Russian case study regions, in contrast, give reason for precaution since the occurrence of drought-induced crisis events seems much more likely in the light of more crucial, overall conditions, namely lower degrees of state capacity and readiness as well as, in the case of India, a high economic susceptibility. However, further improvements are possible given the improved availability of data and the integration of more qualitative information. Additionally, the expansion to further case study regions could help validate the overall concept.     

Using diatoms to assess the impacts of prehistoric, pre-industrial and modern land-use on Danish lakes

The impact of contemporary agriculture on Danish lakes is acknowledged to be extreme. In particular, high loading of nutrients from agricultural soils contributes to the eutrophic conditions found in many of Denmark’s lakes. Palaeolimnological studies have shown that human disturbance of the Danish landscape since the introduction of agriculture around 6,000 years ago has had a major impact on lake ecosystems. The European Union’s Water Framework Directive requires an evaluation of reference conditions for lakes, the conditions expected with only minimal human impact. Monitoring data and palaeolimnological studies of Danish lakes demonstrate that many of the most detrimental effects of eutrophication have been experienced in recent decades. A new study has suggested that the reference status for Danish lakes may be set to the status in ad 1850–1900, probably providing attainable, realistic restoration targets for many sites. The aims of this study were to explore the impacts of past and contemporary land-use on Danish lakes, and to consider how appropriate the use of 1850 as a date to define reference status is for these sites. Catchment land-cover data for ad 1800, taken from historical maps, and sedimentary diatom assemblages of the same age, from dated sediment cores, were used to assess the impact of pre-industrial land-use on 20 Danish lakes. Analysis of contemporary land-cover data and surface-sediment diatom assemblages for the 20 sites was also made. In-lake total phosphorus (TP) concentrations were estimated using the sedimentary diatom assemblages and an existing calibration dataset for Danish lakes. The percentage of the lake catchment that was agricultural land in ad 1800 explained 8.8% of the total variation in the diatom data. The land-cover variables ‘built-up areas’ and ‘plantations’, together explained 16.9% of the variation in the diatom data for the modern samples. Diatom-inferred TP concentrations were high for both ad 1800 (mean 112 μg TP L⁻¹) and the present (mean 122 μg TP L⁻¹), the latter estimates reflecting efforts in recent decades to reduce nutrient loading to Danish lakes following very high levels of nutrient enrichment post-1950. The data presented highlight the impact that human activities 200 years ago, particularly agriculture, had on Danish lake systems. The long cultural history and major anthropogenic disturbance of the Danish landscape mean that true reference conditions for lakes (or ‘baseline’ conditions, those found prior to human impacts) can be found only by considering century to millennial timescales.     

Visioneering: an essential framework in sustainability science

The science of sustainability has inevitably emerged as a vibrant field of research and education that transcends disciplinary boundaries and focuses increasingly on understanding the dynamics of social-ecological systems (SES). Yet, sustainability remains an elusive concept, and its nature seems unclear for the most part. In order to truly mobilize people and nations towards sustainability, we place emphasis on the necessity of understanding the nature, cost and principles of ‘visioneering’—the engineering of a clear vision. In SES, purpose is the most important pillar, which gives birth to vision—the key to fulfilling the systems’ mission. Such a systems perspective leads us to redefine resilience as jumping back to the original purpose, for which SES do not necessarily retain the same structures and functioning after disturbances. A sustainable future will require purpose-driven transformation of society at all scales, guided by the best foresight, with insight based on hindsight that science can provide. Visioneering with resilience-based systems thinking will provide communities with a logical framework for understanding their interconnections and purposes, envisioning a sustainable web of life, and eventually dancing with the systems.     

A stakeholder dialogue on European vulnerability

A stakeholder dialogue was embedded in the ATEAM project to facilitate the development and dissemination of its European-wide vulnerability assessment of global change impacts. Participating stakeholders were primarily ecosystem managers and policy advisers interested in potential impacts on ‘Agriculture’, ‘Forestry’, ‘Water’, ‘Carbon storage’, ‘Biodiversity’ and ‘Mountain environments’ sectors. First, stakeholder dialogue approaches to integrated assessment are introduced. Methodological considerations on stakeholder selection and dialogue implementation and evaluation follow. The dialogue content and process are evaluated from the perspectives of stakeholders and scientists. Its usefulness in the research process and the relevance of outcomes for stakeholders are particularly considered. The challenging compromises required to perform innovative research, which seeks to achieve both peer scientific credibility and societal relevance, are emphasized. Effective stakeholder dialogues play a substantial role in raising the visibility and meaningfulness of vulnerability assessments as critical means to improve awareness on global change and its potential worrying impacts on society. They further provide scientists with critical information on ecosystem management and sectoral adaptive capacity. These processes of mutual learning and knowledge exchange moreover foster a better understanding of the potential and limits of global change modelling and vulnerability assessment for policy and ecosystem management.

Conversion of specialised dairy farming systems into sustainable mixed farming systems in Cuba

From the 1960s onwards, a ‘High External Input’ dairy production model was applied widely in Cuba. Overall milk production of the national herd increased considerably, but the system was inefficient from both a financial and energetic point of view. In the early 1990s, after the abrupt end of inflow of capital and other resources from Eastern Europe, the dairy sector collapsed. In the short term, the modern infrastructure of milk production deteriorated and the sector experienced profound vulnerability. However, in the longer term, this situation stimulated a search for more sustainable approaches, such as low external input Mixed Farming Systems (MFS). The current study aimed to evaluate two small scale prototype farms to assess the implications of converting ‘Low External Input’ Dairy Farming Systems into MFS. Fifteen agro-ecological and financial indicators were selected and monitored over a 6-year period. Two configurations of MFS, i.e. the proportion of the farm area occupied by arable crops, were tested: 25 and 50%. Productivity, energy efficiency and cost-effectiveness all improved following conversion. Total energy input was low for both farms and decreased over time, whereas energy efficiency was high and increased over time. Human labour input was high directly following conversion, but decreased by one-third over the 6-year period. This study demonstrates, at an experimental scale, the potential of MFS to achieve ecological, productivity and financial advantages for dairy production in Cuba.

Perceptions toward stewardship among residents living near U.S. Department of Energy Nuclear Facilities

Although stewardship has been widely defined and used in environmental management and planning, there is a dearth of studies that describe how the lay public perceives this concept. A national sample of residents in 14 states who live near DOE nuclear facilities were interviewed to delineate public understanding and awareness of the stewardship program of the U.S. Department of Energy (DOE). This study discusses the findings of the survey and discusses how institutional trust influences public participation and resident’s choices of potential stewards. Almost 40% of the respondents could not define stewardship; those who did, believed that ‘responsibility,’ ‘management,’ and ‘accountability’ are key elements of stewardship. In addition, about a third of the respondents identified Federal groups and the DOE as potential stewards.

Resilience and collapse of artisanal fisheries: a system dynamics analysis of a shellfish fishery in the Gulf of California, Mexico

Analyzing different pathways by which social–ecological systems can loose resilience and enter trajectories of collapse constitutes an important aspect of our quest towards understanding resource sustainability. This paper’s goal was to better understand the effect of a particular class of disturbance—the accumulative effects of routine stressors—in the context of marine social–ecological systems. To that effect, we built a system dynamics model using empirically collected institutional and biological field data of an artisanal fishery in the Gulf of California, Mexico. Among our findings, we identified different scenarios under which even very small endogenous changes in the relationship between ecological and institutional variables can send a seemingly resilient system into a trajectory of collapse. We discuss why these types of disturbances are so difficult to prevent and be identified by the users of the resource, as well as potential strategies to address these challenges.     

Integrating the social and natural sciences in environmental research: a discussion paper

This paper considers the practical and intellectual challenges that attend efforts to integrate the social and natural sciences in environmental research, and the broader political, social and economic context in which this takes place. Based on the experiences of researchers in Australia—but with obvious relevance for researchers in many countries—it is the outcome of an interdisciplinary workshop which brought together social and natural scientists involved in environmental management. This event and the wider discussions that followed were initiated to enable researchers to exchange ideas about the obstacles to interdisciplinary collaboration, and to discuss ways to overcome these. The paper provides a summary of the issues and proposes some guidelines for interdisciplinary collaboration. These may be summarised as follows:
