At the time of its introduction in the end of the 1980s, the concept of natural capital represented new, more ecologically aware thinking in economics. As a symbol of novel thinking, the metaphor of natural capital stimulated a debate between different disciplinary traditions on the definitions of the concept and research priorities and methods. The concept became a means to control the discourse of sustainable development. In this paper, I focus on the power/ knowledge implications of the use of the (...) concept, and I follow the career of the concept of natural capital in ecological economic publications between the years 1988 and 2000. The main interests are in the use of the concept to affect the rules according to which claims concerning sustainable development can be made and in the constitution of objects of environmental knowledge.

Intergenerational impartiality requires putting the welfare of future generations at par with that of our own. However, rational choice requires weighting all welfare values by the respective probabilities of realization. As the risk of non-survival of mankind is strictly positive for all time periods and as the probability of non-survival is cumulative, the probability weights operate like discount factors, though justified on a morally justifiable and completely different ground. Impartial intertemporal welfare maximization is acceptable, though the welfare of people in (...) the very far future has lower effects as the probabilities of their existence are also lower. However, the effective discount rate on future welfare values (distinct from monetary values) justified on this ground is likely to be less than 0.1 per annum. Such discounting does not compromise environmental protection and sustainability unduly. The finiteness of our universe implies that the sum of our expected welfare to infinity remains finite, solving the paradox of having to compare different infinite values in optimal growth/conservation theories.

The notion that the idea of nature isnot quite the unbiased rule to designsustainable futures is obvious. But,nevertheless, questions about nature, how itfunctions and what it might aim at, is leadingthe controversial debates about bothsustainability and biotechnology. These tworesearch areas hardly have the same theorybackground. Whereas in the first concept, theidea of eternal cyclical processes is basic,the latter focuses on optimization. However,both concepts can work together, but only undera narrow range of public acceptance in Europe.The plausibility of arguments for usingbiotechnology (...) within sustainable technologiesvaries according to the assumed part natureitself plays for reaching optimized states. Theculture related vision of nature's functionshas impact on agricultural biotechnology,dealing not only with food crops but also withnon-food plants like renewable resources thatare used for energy or fiber production. Theseplants are grown to reach sustainabledevelopment. However, there is a fundamentaldifference between regarding biofuels as``renewable'' and ``regenerative,'' due to thetension between the concepts of ``the natural''and ``the sustainable.'' Arguments ofoptimization, efficiency, and efficacy arecritically discussed in order to take thepresent need for sustainable technologies forserious. (shrink)

For decades there has been a controversial debate over how far religious faith communities are specifically engaged in ecological practices (EP). Therefore we studied four Austrian and two German Benedictine monasteries religious ethics and spirituality as a means of a driving force for initiating EP. We draw upon theories of organizational learning processes and capacity-building of sustainability to interpret our empirical findings. The majority of monasteries are highly engaged in EP, initiated either as an outcome of individual activities or through (...) a specific mostly informally acting group, but rarely an organizationally or systematically integrated goal of the monasteries, or a focus of capacity building. Monasteries follow a technical and economic decision-making process in implementing EP. Spirituality plays a limited role in the initiation of EP. The environment of monasteries–acceptance or critique against ecological practices–influences the monasteries decisions. Institutionalization of ecological practices into the monasteries organizational structure is rare. (shrink)

Ecological economics is an interdisciplinary science that is primarily concerned with developing interventions to achieve sustainable ecological and economic systems. While ecological economists have, over the last few decades, made various empirical, theoretical, and conceptual advancements, there is one concept in particular that remains subject to confusion: critical natural capital. While critical natural capital denotes parts of the environment that are essential for the continued existence of our species, the meaning of terms commonly associated with this concept, such as ‘non-substitutable’ (...) and ‘impossible to substitute,’ require a clearer formulation then they tend to receive. With the help of equations and graphs, this article develops new definite account of critical natural capital that makes explicit what it means for objective environmental conditions to be essential for continued existence. The second main part of this article turns to the question of formally modeling the priority of conserving critical natural capital. While some ecological economists have maintained that, beyond a certain threshold, critical natural capital possesses absolute infinite value, absolute infinite utility models encounter significant problems. This article shows that a relative infinite utility model provides a better way to model the priority of conserving critical natural capital. (shrink)

The core question of this article is: how can we take account of the future and future generations if our knowledge of the future is so sparse? The importance of the future is discussed within the framework of our concept of time. After that it is argued that future generations do not constitute a new, let alone unique, element in the debate on the future. Two different routes to acquire knowledge about the future and prepare for the future are described. (...) Both reflect facts and values of the present and the past instead of giving an accurate picture of the future. Finally the view is defended that future -focused activity should be based to a greater extent on durable principles. Some of these durable principles are presented and discussed. (shrink)

La littérature économique s’intéresse aux enjeux du développement soutenable, mais elle aborde rarement le pilier social, car elle se concentre sur l’imbrication entre les piliers économique et environnemental. Quand il est pris en compte, le pilier social l’est comme interface qui facilite la jointure entre les deux autres. Les analyses économiques soulignent unanimement l’importance d’effectuer cette jonction, qu’il s’agisse d’évoquer les conditions de vie des populations ou l’acceptation sociale des transformations vers une transition écologique. Pourtant, les études consacrées au développement (...) soutenable ne considèrent guère le social autrement que comme une simple interface. Le social doit trouver sa juste place dans les politiques économiques de développement soutenable. Pour cela, il importe de reconceptualiser ce pilier en le faisant entrer en résonance avec les thèmes à l’origine du développement soutenable. De nouvelles justifications se présentent alors pour des politiques publiques pensées jusque là en dehors du développement soutenable. Classification JEL : Q01, Q56, Z13. (shrink)

Environmental ethics is the discipline in philosophy that studies the moral relationship of human beings to, and also the value and moral status of, the environment and its nonhuman contents. This entry covers: (1) the challenge of environmental ethics to the anthropocentrism (i.e., humancenteredness) embedded in traditional western ethical thinking; (2) the early development of the discipline in the 1960s and 1970s; (3) the connection of deep ecology, feminist environmental ethics, and social ecology to politics; (4) the attempt to apply (...) traditional ethical theories, including consequentialism, deontology, and virtue ethics, to support contemporary environmental concerns; and (5) the focus of environmental literature on wilderness, and possible future developments of the discipline.

This dissertation is a contribution to the debate about ‘climate justice’, i.e. a call for a just and feasible distribution of responsibility for addressing climate change. The main argument is a proposal for a cautious, practicable, and necessary step in the right direction: given the set of theoretical and practical obstacles to climate justice, we must begin by making contemporary development practices sustainable. In times of climate change, this is done by recognising and responding to the fact that emissions of (...) greenhouse gases, with climate change as their result, are an immanent threat to any reflectively embraced development project. In the universal pursuit of progress, basic needs of both present and future people are put at risk. Even so, a political stalemate and business-as-usual prevail. The situation is locked up by an uncertainty about the exact impacts of choices made and by the reasonable disagreement of modern societies. The result is passiveness, and the passing on of a slowly and indiscernibly growing problem to future generations. This dissertation brings out a crucial message about the need to make our development sustainable. Instead of delaying action through trying to resolve the intractable epistemic and normative uncertainty fully, the focus should be on vindicating already shared points of practical convergence. On the constructivist method here adopted, the task is to characterise the agent and the situation faced from a practical and first-person point of view. More specifically, to specify the practical problem climate change gives rise to; the moral importance of needs (chapter three); how a principled priority of basic needs can be defended (chapter four), intergenerationally (chapter five) and internationally (chapter six); and what natural and social limits there are to development (chapter seven). These conceptions narrows the practice of development in the present context: it can be concluded that development must not risk the basic needs of anyone implicated. This common ground brackets off disagreement irrelevant to the urgent need to act, and so brings together otherwise deeply divided agents. A sufficientarian basic needs-principle, as the focus of an overlapping consensus, is practicable and anticipatory in the disuniting moral conundrum of climate change. (shrink)
