This paper reports on the design and implementation of a multi-phase interactive process among a set of scientists, policy makers, land managers, and community representatives, so as to facilitate communication, mutual understanding, and participative decision making. This was part of the Ecosystem Services Project in Australia. The project sought to broaden public understanding about the natural ecosystems in Australia. The study reported here pertains to one of the project sites--the Goulburn Broken catchment, a highly productive agricultural watershed in the south-east (...) of Australia. The paper demonstrates how, starting from a condition of diversity of ideas and interests among the participants, systematic dialogue and mutual learning could be generated, leading to identification of options for more sustainable land management practices. The concept of "ecosystem services" was used as an integrative tool across disciplines and community perspectives. The concept of scenarios was used to encourage future-focussed thinking among the participants. The idea of "stakeholder jury" was used to promote deliberation. A process of multi-criteria evaluation was used to facilitate convergence of viewpoints, through informed trade-offs and compromises. This experience led to the development of a process for integration research, which helped in harmonising across diverse understandings and values in a transparent and structured manner. (shrink)

Describing resources and their relationships with organisms seems to be a useful approach to a ‘unified ecology’, contributing to fill the gap between natural and human oriented processes, and opening new perspectives in dealing with biological complexity. This Resource Criterion defines the main properties of resources, describes the mechanisms that link them to individual species, and gives a particular emphasis to the biosemiotic approach that allows resources to be identified inside a heterogeneous ecological medium adopting the eco-field model. In particular, (...) this Criterion allows to couple matter, structured energy and information composing the ecological systems to the biosemiotic and cognitive mechanisms adopted by individual species to track resources, transforming neutral surroundings into meaningful species-specific Umwelten. The expansion of the human semiotic niche that is a relevant evolutionary process of the present time, assigns the role of powerful and efficient agency to the Resources Criterion to evaluate the effect of human intrusion into the natural systems with habits of key stone species, under the challenge of a growing use of alloctonous, immaterial and symbolic resources of the actual globalized societal models. The Resource Criterion interprets the ecological dynamics contributing to complete the epistemology of the ecology, to open a bridge toward economy and other societal sciences, and to contribute to formulate a General Theory of Resources.

While acknowledging the absence of a single definition or theory of sustainability, this paper argues that a discussion of sustainability which refers only to definitions is pointless without an understanding of how the definitions are operationalised. In this context, the paper considers the operationalisation of strong sustainability. The definitions and operationalisation of strong sustainability most closely associated with (i) neoclassical environmental economics and (ii) ecological economics are discussed and compared. This analysis raises questions about the extent to which ecological economics (...) has been able to influence real-world decisions and policy. The paper ends by considering whether the economic and political power structure taken as given by ecological economics is compatible with its policy perspective. (shrink)

Economic markets are not morally free zones. Contrary to popular misconceptions, market functioning rests on the ethical principles of fairness and voluntariness. This ethical foundation can be traced back at least to moral philosopher Adam Smith, one of the founders of modern economics. In the inconspicuous form of microeconomic axioms, these moral foundations are preserved. Thus, virtually all “neo-classic” economic concepts presuppose a market ethics of fairness and voluntariness. In a world of pervasive uncertainty on the long-term development of the (...) human-environment interaction, the protection of the global life-support systems is an important test case for the scope of the ethical content of market ethics. We review risk protection strategies in the face of this uncertainty that are (i) based on the insurance effect of biological diversity, and (ii) that employ a safe minimum standard (SMS). Because the fairness principle of market ethics requires that economic agents who cause “external” costs must, at least, compensate those who are burdened with these costs, the interests of future generations have to be included in responsible economic decision-making. The market and market ethics approach is applied to the analysis of a SMS for biological diversity, and to the inherent problems of such an approach. At the microeconomic level of individual decision-making, an unconditional protection is supported by market ethics neither for the putative interests of future generations nor for biological diversity: Poor people who struggle to cover their basic needs cannot not be required to care for biological diversity. In all other cases, the protection of biological diversity in favour of future generations is supported—if costs are not “unacceptably high”. At which cost level this point is approached, market ethics is not designed to decide. (shrink)

A frequent justification in the literature for using stated preference methods (SP) is that they are the only methods that can capture the so-called total economic value (TEV) of environmental changes to society. Based on follow-up interviews with SP survey respondents, this paper addresses the implications of that argument by shedding light on the construction of TEV, through respondents’ perspective. It illuminates the deficiencies of willingness to pay (WTP) as a measure of value presented as three aggregated themes considering respondents’ (...) unintentionality, their retraction once they understood that their WTP could be decisive in cost-benefit analysis and the inherent incompleteness of WTP. We discuss why the TEV discourse persists, how it conceals rather than reveals broader notions of value and in what ways our results support the development of alternative approaches that truly endorse plurality in environmental valuation and decision-making.

The European Landscape Convention has brought up the question of democracy in relation to landscape transformation, but without a clear definition of democracy. This paper conceptualises democracy in relation to three main sets of values related to self-determination, co-determination and respect for argument. It examines various methods that have been used to try to make landscape decisions more democratic. In the last part of the paper the connoisseur method is introduced. This method emphasises stakeholder participation in deliberative processes with a (...) particular focus on place-based knowledge. It has been used in Sweden as a means of involving local stakeholders in the democratic process of defining goals and objectives of their landscapes. In the conclusion, this method is recommended despite its dependence on favourable conditions, particularly continuity and commitment, and a few suggestions about possible improvements are presented.

Biodiversity is a term easily applied in different and differing contexts. At first glance it seems to be a biological concept, defined and used in the realm of biological theory, serving for the description of particular aspects of the human and non-human environment. In this sense biodiversity even found its way into the texts of international conventions: “Biological diversity means the variability among living organisms from all sources including, inter alia, terrestrial, marine and other aquatic systems and the ecological complexes (...) of which they are part; this includes diversity within species, between species and of ecosystem.” [Harper and Hawksworth (1995)] But despite this clear and distinct definition, the intension of the term BD seems to be ambiguous. This is true for the single aspects of the definition itself, for example, the discussion over “what is a species?” took place in biology during the last 200 years and it is far from being finished [Claridge et al. (1997) Species]. This discussion asks not only for the “correct” biological definition of the term, but at the same time the methodological status of this term is in question. The result of this situation can be seen in the existence of at least 10–20 different definitions, considering biological as well as methodological aspects [Bachmann (1998) Theor Biosci 117:213–230]. Setting aside the fundamental scientific problems even the application of the term, its parametrisation and finally its relevance for biological theory-building is subject matter of controversies. The same is true for further particles of the definition, e.g. the term “ecosystem”, “complexity”, “gen”, “organisms”, etc. The intensity of the debate contrasts in a peculiar way to the reaction of (non-evolutionary) biologists, insofar as the biological research seems to be untouched by the irritating results of the debate itself. Referring to this strange situation, the aim of our article is a reconsideration of the term “biodiversity”. From an epistemological point of view it can be shown that a definition of biodiversity is possible which does not refer to biological knowledge and know-how—at least in its very first steps. Biodiversity then turns out to be a metaphor for specific aspects of societal organisation, the structuration and reproduction of nature-society relations within societies, and not for biological facts at all.

This paper attempts to assess and evaluate some of the economic implications of the Convention on Biological Diversity. After outlining the main principles and the scope of this Convention, the following issues are addressed: the determination of the 'optimal' level of biodiversity loss, the meaning of incremental costs, and monetary evaluation problems of ecological resources and the problems it poses for the funding mechanism. The paper concludes with a discussion of the issues of commercialisation and access to genetic resources.

Estimates of the marginal damage costs of carbon dioxide emissions suggest that, although climate change is a problem and some emission reduction is justified, very stringent abatement does not pass the cost-benefit test. However, current estimates of the economic impact of climate change are incomplete. Some of the missing impacts are likely to be positive and others negative, but overall the uncertainty seems to concentrate on the downside risks and current estimates of the damage costs may have a negative bias. (...) The research effort on the economic impacts of climate change is minute and lacks diversity. This field of study should be strengthened, with a particular focus on the quantification of uncertainties; estimating missing impacts, estimating impacts in developing countries; interactions between impacts and higher-order effects; the valuation of biodiversity loss; the implications of extreme climate scenarios and violent conflict; and climate change in the very long term. I discuss these particular gaps in research, and speculate on possible sign and size of the impacts of climate change. (shrink)

Contingent valuation surveys generally elicit stated preferences by asking how much a respondent would be willing to pay for an environmental improvement. By drawing on linguistic theory, we propose that the modal phrasing of this question establishes a particular type of commitment towards a hypothetical payment, namely a subjective want or desire. Based on the idea that beyond subjective desires, considerations about what is morally adequate may guide expressed values and that elicitation of these can be linguistically facilitated, we employ (...) an experimental framework to investigate the effects of different modals ( willing, should and appropriate) in the elicitation question on stated preferences. We find that elicited amounts with appropriate are higher than those elicited with willing and should for environmental improvements more associated with use values, while differences are non-significant for environmental improvements more associated with non-use values. We discuss the implications of our findings for stated preference studies, as well as the potential broader theoretical implications that our study entails regarding linguistic representations of the moral entrenchment of environmental values.
