Biodiversity is a valuable resource that supports sustainability within agricultural systems, yet in contradiction to this agriculture is recognised as a contributor to biodiversity loss. Agricultural advisory services are institutions that support sustainable agricultural development, employing a variety of approaches including farmer discussion groups in doing so. This study evaluates the impact of a farmland biodiversity management (FBM) communication strategy piloted within Irish farmer discussion groups. A sensemaking lens was applied in this objective to gain an understanding (...) of how this strategy could create an actionable space for FBM promotion amongst farmers. The strategy was piloted with six Irish dairy farmer discussion groups, after which focus groups were conducted with members of these groups. Additionally, baseline and endline surveys were completed by the members to determine their knowledge, attitude and on-farm practices relating to FBM. Analysis of the focus group data identified that the communication strategy supported the affordance of sensemaking with respect to FBM. Analysis of the data from the baseline and endline surveys relating to knowledge, attitudes and practices found that engaging with the communication strategy promoted farmers to improve their attitude in relation to FBM. Results from this study provide important lessons for agricultural advisory services to support farmers in incorporating FBM into the overall management of their farms and, in turn, to promote the improvement of farmland biodiversity and contribute to a sustainable future.

The recent conception of biodiversity proposed by James Maclaurin and Sterelny was developed mostly with macrobiological life in mind. They suggest that we measure biodiversity by dividing life into natural units (typically species) and quantifying the differences among units using phenetic rather than phylogenetic measures of distance. They identify problems in implementing quantitative phylogenetic notions of difference for non-prokaryotic species. I suggest that if we focus on microbiological life forms that engage in frequent, promiscuous lateral gene transfer (LGT), (...) and their associated reticulated phylogenies, we need to rethink the notion of species as the natural unit, and we discover additional problems with phylogenetic notions of distance. These problems suggest that a phenetic approach based on morphospaces has just as much appeal, if not more, for microbes as they do for multi-cellular life. Facts about LGT, however, offer no new insight into the additional challenge of reconciling units and differences into a single measure of biodiversity. (shrink)

Taking the regime established by the Convention on Biological Diversity as a foundation, the purpose of this article is twofold. First, it examines how the international biodiversity regime integrates the private property paradigm into its toolbox for conservation and sustainability and then critically evaluates the shortcomings of the intellectual property mechanism. Second, it argues that the increasing ubiquity of open access emerging technologies should lead the international community to carefully assess the benefits for conservation research of reverting to a (...) framework that places biodiversity within the global commons. The impasse between global commons advocates and the intellectual property status quo obscures the underlying problematic of the “commodity fiction” of biodiversity and increasing use of digital sequence information likely exacerbates power asymmetries. One remedy explored here is an alternative to these two approaches that dislodges rather than discards the concept of private property. Drawing inspiration from Polanyi and building on May (2010), the article shows how a hybrid approach bridging a public and private conception of genetic resources and traditional knowledge could more effectively and equitably distribute benefits to countries and communities providing resources of value to industry.

In a world of massive extinctions where not all taxa can be saved, how ought biologists to decide their preservation priorities? When biologists make recommendations regarding conservation, should their analyses be based on scientific criteria, on public or lay criteria, on economic or some other criteria? As a first step in answering this question, we examine the issue of whether biologists ought to try to save the endangered Florida panther, a well known glamour taxon. To evaluate the merits of panther (...) preservation, we examine three important arguments of biologists who are skeptical about the desirability of panther preservation. These arguments are (1) that conservation dollars ought to be spent in more efficient ways than panther preservation; (2) that biologists and conservationists ought to work to preserve species before subspecies; and (3) that biologists and conservationists ought to work to save habitats before species or subspecies. We conclude that, although all three arguments are persuasive, none of them provides convincing grounds for foregoing panther preservation in favor of other, more scientifically significant conservation efforts. Our conclusion is based, in part, on the argument that biologists ought to employ ethical, as well as scientific, rationality in setting conservation priorities and that ethical rationality may provide persuasive grounds for preserving taxa that often are not viewed by biologists as of great importance.

Why should governments or individuals invest time and resources in conserving biodiversity? A popular answer is that biodiversity has both instrumental value for humans and intrinsic value in its own right. Defending Biodiversity critically evaluates familiar arguments for these claims and finds that, at best, they provide good reasons for conserving particular species or regions. However, they fail to provide a strong justification for conserving biodiversity per se. Hence, either environmentalists must develop more compelling arguments for (...) conserving biodiversity or else they should modify their agenda. This short precis is an overview of the central findings of our book. (shrink)

This article evaluates the moral implications of two leading theories on biodiversity preservation/conservation (Paul Taylor's biocentric egalitarianism and J. Baird Callicott's holistic communitarianism). Taylor argues for the moral equality of all members of the Earth's community of life, calling for an ethic of respect for nature to conserve biodiversity. Callicott argues for the moral consideration of ecosystems to maintain their integrity, stability, and beauty. The article makes two major claims. First, we need a plausible account of moral egalitarianism (...) to disrupt ethical anthropocentrism. Second, the ethics of respect for nature requires a critical bottom-up character-based ethical theory to be morally forceful. These missing elements are central to the ubuntu philosophy about personhood and are significant for enriching egalitarian-communitarian solutions to biodiversity loss. (shrink)

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. (shrink)

Explora-se o conceito de que a diversidade propicia robutez nos sistemas processadores de informação e como seria aplicável às areas neurais e sociais, incluindo o fenômeno religioso.

Palavras-chave : Estabilidade; Sistema; Evolução; Biologia; Sociedade; Cognição; Afetividade; Essência; Transcendência; Hipótese; Verdade.The concept that diversity propitiates robustness in information processing systems is explored and indicated to be applicable in the neural and social areas, including the religious phenomenon. Evaluation of statistics in populations indicates that the latter is not essential to the human, in spite of being a constant among cultures. Cognitive and affective aspects in science and religion are discussed under the proposition that adequate demarcation may help in reducing conflicts. Elaboration on the tensions between truths – deterministic – and freedom may contribute in the same direction. Tensions may arise from the utilization of the concepts of strong and weak concepts of belief, that is, between beliefs and seemingly fruitful hypotheses – deserving credits of trustfulness.

KATIE McSHANE | : Taking the Fifth Assessment Report of the Intergovernmental Panel on Climate Change as representative, I argue that animal ethics has been neglected in the assessment of climate policy. While effects on ecosystem services, biodiversity, and human welfare are all catalogued quite carefully, there is no consideration at all of the effects of climate change on the welfare of animals. This omission, I argue, should bother us, for animal welfare is not adequately captured by assessments of (...) ecosystem services, biodiversity, or human welfare. After describing the paper’s assumptions and discussing the role of the IPCC’s Assessment Reports in climate policy, I consider the presentation of climate impacts in the IPCC’s Fifth Assessment Report, noting the aspects of animal welfare that are considered there, and comparing the report’s treatment of animal welfare to its treatment of human welfare. Next, I argue that the concepts of ecosystem services, biodiversity, and human welfare do not adequately capture the welfare of animals. Finally, I discuss concerns about human responsibility for animal welfare and the practicality of including considerations of animal welfare among the climate impacts studied by the IPCC. | : En prenant le Cinquième Rapport d’évaluation du Groupe d’experts intergouvernemental sur l’évolution du climat à titre de cas représentatif, je soutiens que l’éthique animale a été négligée dans l’évaluation de la politique climatique. Alors que les effets sur les services écosystémiques, la biodiversité et le bien-être humain y sont tous soigneusement recensés, les effets du changement climatique sur le bien-être des animaux n’y sont aucunement pris en considération. Je soutiens que cette omission devrait nous préoccuper, étant donné que l’évaluation des services écosystémiques, de la biodiversité et du bien-être humain ne rend pas compte adéquatement du bien-être des animaux. Après avoir décrit les présupposés de l’article et réfléchi au rôle des Rapports d’évaluation du GIEC quant à la politique climatique, j’examine la présentation des effets climatiques dans le Cinquième Rapport du GIEC, en indiquant les aspects du bien-être animal qui y sont pris en considération, tout en comparant le traitement que fait le rapport du bien-être animal à celui qui est fait du bien-être humain.

How should billions of species observations worldwide be shared and made reusable? Many biodiversity scientists assume the ideal solution is to standardize all datasets according to a single, universal classification and aggregate them into a centralized, global repository. This ideal has known practical and theoretical limitations, however, which justifies investigating alternatives. To support better community deliberation and normative evaluation, we develop a novel conceptual framework showing how different organizational models, regulative ideals and heuristic strategies are combined to form (...) shared infrastructures supporting data reuse. The framework is anchored in a general definition of data pooling as an activity of making a taxonomically standardized body of information available for community reuse via digital infrastructure. We describe and illustrate unified and pluralistic ideals for biodiversity data pooling and show how communities may advance toward these ideals using different heuristic strategies. We present evidence for the strengths and limitations of the unification and pluralistic ideals based on systemic relationships of power, responsibility and benefit they establish among stakeholders, and we conclude the pluralistic ideal is better suited for biodiversity data.

Researchers working in the field of ecosystem services (ES) have long acknowledged the importance of recognising multiple values in ecosystems and biodiversity. Yet the operationalisation of value pluralism in ES assessments remains largely elusive. The aim of this research is to present a taxonomy of values and valuation methods to widen the evaluative space for ES. First, we present our preanalytic positions in regards to the values and valuation of ES. Second, we review different value definitions that we deem (...) relevant for the discussion of ES valuation. Third, we propose a taxonomy of ES values based on different conceptions of human-nature relationships. Finally, we present a taxonomy of different methods that can be used to recognise plural values in ES. This taxonomy for a plural valuation can help ES scientists and practitioners with their aim of representing people's multiple and context-specific ways of valuing nature. The taxonomy can also serve to pay broader attention to ES values that are overlooked or misrepresented in assessments that restrict their focus to monetary valuations. (shrink)

Nowadays, on national and international levels, the law has been increasingly considering local and traditional communities’ role for achieving conservation. In Brazil, for instance, one can see how recent legal rules promote benefits for those local groups who practice low environmental impact activities. Nevertheless, regarding traditional fishing communities that live on the coastal zone, a region where many protected areas have been created lately in Brazil, the positive social effects of those measures are often undermined by the economic and political (...) pressure they suffer. This becomes particularly clear when the problem is seen under the different grades of citizenship people face in Brazil: that is, considering how people can be over-included in the legal system to have mainly access to its benefits, while others are under-included to be mainly dependent on it. It seems that Brazilian coastal fishing communities fall into the latter case, and that would explain how they are subject to many different types of restrictions and responsibilities due to the new legal instruments that are being developed to protect such areas, sometimes causing, for instance, a pressure to remove them from their homes. Conservation in this context, then, is to be understood beyond legal texts and, especially, under the evaluation of the social conditions these populations are submitted to. Therefore, this paper sketches the legal development of Brazilian marine protected areas, points out some examples of conflicts involving traditional fishing communities affected by conservation policies, and conceptualizes the relations of over- and under-inclusion they can be considered as part of.

If non-human animals experience wellbeing and suffering, such welfare consequences arguably should be included in a social welfare evaluation. Yet economic evaluations almost universally ignore non-human animals, in part because axiomatic social choice theory has failed to propose and characterize multi-species social welfare functions. Here we propose axioms and functional forms to fill this gap. We provide a range of alternative representations, characterizing a broad range of possibilities for multi-species social welfare. Among these, we identify a new characterization of (...) additively-separable generalized (multi-species) total utilitarianism. The multispecies setting permits a novel, weak species-level separability axiom with important consequences. We provide examples to illustrate that non-separability across species is implausible in a multi-species setting, in part because good lives for different species are at very different welfare levels. Finally, we explore the consequences for evaluating climate policy and understanding speciesism and non-climate environmental goals, such as biodiversity. (shrink)

In the discussion about consequences of the release of genetically modified (GM) crops, the meaning of the term “environmental damage” is difficult to pin down. We discuss some established concepts and criteria for understanding and evaluating such damages. Focusing on the concepts of familiarity, biological integrity, and ecosystem health, we argue that, for the most part, these concepts are highly ambiguous. While environmental damage is mostly understood as significant adverse effects on conservation resources, these concepts may not relate directly to (...) effects on tangible natural resources but rather to parameters of land use or ecological processes (e.g., the concept of biological integrity). We stress the importance of disclosing the normative assumptions underlying damage concepts and procedures for the evaluation of damages by GM crops. A conceptualization of environmental damage should precede its operationalization. We recommend an unambiguous definition for damage developed earlier and recommend that evaluation criteria be based on this. However, a general damage definition cannot replace case-specific operationalization of damage, which remains an important future challenge. (shrink)

Neobiota as non-native species are commonly considered as alien species. The Convention on Biological Diversity (CBD) intends to “prevent the introduction of, control or eradicate those alien species which threaten ecosystems, habitats or species”. The European Union has financed the DAISIE research project for the first pan-European inventory of Invasive Alien Species (IAS), which is supposed to serve as a basis for prevention and control of biological invasions. This paper discusses the evaluation approach for classifying “100 of the Worst” (...) IAS in Europe by the EU DAISIE research project. The main impact categories used by DAISIE for assorting “100 of the Worst” IAS are investigated and the texts of the “Wanted” species factsheets are examined. Two examples from the DAISIE factsheets of the “100 of the Worst” IAS [Tree of Heaven ( Ailanthus altissima ) and the Raccoon ( Procyon lotor )] are discussed to illustrate DAISIE’s biodiversity evaluation approach in more detail. However, the classification criteria used by DAISIE do not allow for sufficiently differentiating these neobiota from an ecological behavior of native species with a similar ecological niche. In conclusion, neobiota evaluations are not comprehensive when they refer mainly to the successful expansion and competition with native species into available ecological niches. A comprehensive assessment of the impacts of neobiota on biodiversity and humans needs to take into account the different values of biodiversity as mentioned in the preamble of the CBD. (shrink)

Abstract - Evolutionary, ecological and ethical studies are, at the same time, specific scientific disciplines and, from an historical point of view, structurally linked domains of research. In a context of environmental crisis, the need is increasingly emerging for a connecting epistemological framework able to express a common or convergent tendency of thought and practice aimed at building, among other things, an environmental policy management respectful of the planet’s biodiversity and its evolutionary potential. -/- Evolutionary biology, ecology and ethics: (...) at first glance, three different objects of research, three different worldviews and three different scientific communities. In reality, there are both structural and historical links between these disciplines. First, some topics are obviously common across the board. Second, the emerging need for environmental policy management has gradually but radically changed the relationship between these disciplines. Over the last decades in particular, there has emerged a need for an interconnecting meta-paradigm that integrates more strictly evolutionary studies, biodiversity studies and the ethical frameworks that are most appropriate for allowing a lasting co-evolution between natural and social systems. Today such a need is more than a mere luxury, it is an epistemological and practical necessity. -/- In short, the authors of this volume address some of the foundational themes that interconnect evolutionary studies, ecology and ethics. Here they have chosen to analyze a topic using one of these specific disciplines as a kind of epistemological platform with specific links to topics from one or both of the remaining disciplines. Michael Ruse’s chapter, for instance, elucidates some of the structural links between Darwinismand ethics. Ruse analyzes the Evolutionism vs. Creationism debate, emphasizing the risks run by scientists when they ideologize the scientific content of their studies. In the case of the contributions of Jean Gayon and Jean-Marc Drouin, which respectively deal with the disciplines of evolutionary biology and ecology, some central connections have been developed between these two disciplines, while reserving the option to consider in detail their topic in order to discover essential features ormeanings. Gayon analyzes the multilayered meanings of “chance” in evolutionary studies and the methodological implications that accompany such disparatemeanings. Froma similar analytical perspective, Drouin’s contribution focuses on the identification and critical evaluation of the different conceptions of time in ecology. Chance and time, factors of evolution in species and ecological systems, play a very important function in both disciplines, and these chapters help to capture their polysemous structure and development. Bryan Norton’s chapter, on adaptive environmental management, is set within an epistemological context where the Darwinian paradigm, ecological knowledge and ethical frameworks meet to give rise to practical, conservationist policies. In his contribution, Patrick Blandin pleads for the necessity of an eco-evolutionary ethics capable of fully encompassing humanity’s responsibility in the future determination of the biosphere’s evolutionary paths. Our value systems must recognize the predominant place that humanity has taken in the evolutionary history of the planet, and integrate the ethical ramifications of scientific advances in evolutionary and ecological studies. The chapter by J. Baird Callicott introduces us to a metaphorical ecological reversion with direct consequences for our moral conduct. If ecology showed that ecosystems are not organisms, recognizing organisms as a kind of ecosystem could be the basis for a new post-modern ecological ethics that lays the foundation for a better moral integration of humans with the environment. The contributions of Robin Attfield and Tom Regan delve into some of the classical issues in environmental ethics, situating them within a broader ecological and evolutionary context. Attfield’s chapter tackles the confrontation between individualistic and ecologically holistic perspectives, their different approaches to the issue of intrinsic value, and their tangled relation to monism and pluralism. Regan’s contribution ponders the criteria that allow individual beings, human and non-human, to own moral rights, the role of the struggle for existence in the relationship between species, and the logical difficulties involved in attributing intrinsic value to collective entities (species, ecosystems). Catherine Larrère’s chapter discusses the opposition between two environmental and ethical worldviews with very different philosophical centers of gravity: nature and technology. These opposing perspectives have direct consequences not only for the perception of the problems at hand and for what entities are deemed morally significant, but also for the proposed solutions. -/- To set out some foundational events in the history of evolutionary biology, ecology and environmental ethics is a first necessary step towards a clarification of their major epistemological orientations. On the basis of this inevitably nonexhaustive history, it will be possible to better position the work of the different contributors, and to build a meta-paradigm, i.e. a connecting epistemological framework resulting from one common or convergent tendency of thought and practice shared by different disciplines.

Although agriculture in Australia is very productive, the current food supply systems in Australia fail to deliver healthy diets to all Australians and fail to protect the natural resources on which they depend. The operation of the food systems creates ‘collateral damage’ to the natural environment including biodiversity loss. In coming decades, Australia’s food supply systems will be increasingly challenged by resource price inflation and climate change. Australia exports more than half of its current agricultural production. Government and business (...) are aiming to substantially increase production to bolster exports. This will increase pressure on agricultural resources and exacerbate ‘collateral’ damage to the environment. The Australian public have a deep and ongoing interest in a very wide range of issues associated with the food systems including the environment, health and sustainability. Food is something we require in order to live and a good diet is something we have to have to be healthy. For health over a life-time we need food security. However, we also require a range of other material goods and social arrangements in order to develop and flourish as human beings. And we need these other things to be secure over a life-time. Food is therefore one security among a range of other securities we need in order to flourish. The paper outlines a number of approaches, as examples, that help to identify what these other goods and arrangements might be. The approaches mentioned in this paper include human rights, national securities, human needs, authentic happiness, capabilities, sustainability and environmental ethics. The different approaches provide a way of evaluating the current situation and indicating a direction for change within the food systems that will address the problems. However, changing large systems such as those involved in food supply is difficult because inertias and vested interests make the current food supply systems resilient to change. The paper suggests that one of the first and ongoing tasks is to develop an understanding of the situation from a comprehensive social–ecological systems perspective. The paper also suggests that a practical leverage point for system change is restructuring the flow of information on the health, natural resources and biodiversity loss issues related to the food supply systems.

Each year, over 200 million people are infected with the malaria parasite, nearly half a million of whom succumb to the disease. Emerging genetic technologies could, in theory, eliminate the burden of malaria throughout the world by intentionally eradicating the mosquitoes that transmit the disease. In this paper, we offer an ethical examination of the intentional eradication of Anopheles gambiae, the main malaria vector of sub-Saharan Africa. In our evaluation, we focus on two main considerations: the benefit of alleviating (...) the malaria burden, and the loss of value that would accompany the eradication of the species. We outline a typology of the different ways in which species are valued or could be valuable, then use that typology to appraise the value of the species in question. We argue that Anopheles gambiae has minor (and redundant) instrumental value, little final subjective value and no objective final value. (shrink)

This book examines the threat that climate change poses to the projects of poverty eradication, sustainable development, and biodiversity preservation. It offers a careful discussion of the values that support these projects and a critical evaluation of the normative bases of climate change policy. This book regards climate change policy as a public problem that normative philosophy can shed light on. It assumes that the development of policy should be based on values regarding what is important to respect, (...) preserve, and protect. What sort of climate change policy do we owe the poor of the world who are particularly vulnerable to climate change? Why should our generation take on the burden of mitigating climate change that is caused, in no small part, by emissions from people now dead? What value is lost when natural species go extinct, as they may well do en masse because of climate change? This book presents a broad and inclusive discussion of climate change policy, relevant to those with interests in public policy, development studies, environmental studies, political theory, and moral and political philosophy.

This work proposes a coevolutionary theory of aesthetics that encompasses both biotic and human arts. Anthropocentric perspectives in aesthetics prevent the recognition of the ontological complexity of the aesthetics of nature, and the aesthetic agency of many non-human organisms. The process of evaluative coevolution is shared by all biotic advertisements. I propose that art consists of a form of communication that coevolves with its own evaluation. Art and art history are population phenomena. I expand Arthur Danto’s Artworld concept to (...) any aesthetic population of producers and evaluators. Current concepts of art cannot exclusively circumscribe the human arts from many forms of non-human biotic art. Without assuming an arbitrarily anthropocentric perspective, any concept of art will need to engage with biodiversity, and either recognize many instances of biotic advertisements as art, or exclude some instances of human art. Coevolutionary aesthetic theory provides a heuristic account of aesthetic change in both human and biotic artworlds, including the coevolutionary origin of aesthetic properties and aesthetic value within artworlds. Restructuring aesthetics, art criticism, and art history without human beings at the organizing centers of these disciplines stimulate new progress in our understanding of art, and the unique human contributions to aesthetics and aesthetic diversity.

Ecological and livable cities need an objective method to be judged. This paper is in search of a method to determine the level of livability, ecology, and energy efficiency, beginning with ecovillages, ecocities, ending with Tirana capital of Albania. Examples chosen for this methodology are: Ecovillages: 1. Auroville; India; 2. Sieben Linden, Europe; 3. Ecovillages at Ithaca, USA; 4. Ecoovila, Brazil; 5. Mbam and Faoune, Senegal. Ecocities: 1. DongTang, Shangai, China; 2. Masdar, Abu Dhabi, United Arab Emirates; 3. Arcosanti, Arizona, (...) USA; 4. Chang Chun, China; 5. Zira island, Baku Azerbaijan; 6. Globe Town, Nizhny Novgorod, Russia. A special device is introduced for comprising analyze of this paper. Weighing and final score are evaluated in the conclusion. The livable city should be merged with the overall development, ecological progress, sustainable, passive, and bioclimatic design in order to withstand the test of time. Ecological and sustainable cities need to properly make up for the existence weakness of cities construction under fine ecological environment. The intention of this comparative study is an attempt to assess, even improve the lives of the citizens of Tirana, Albania. There are some attempts nowadays to environmentally render the city but due to the lack of a genuine ecological and renewable energy study in Tirana, the city suffers the consequences. The first settlements which consider the renewable energies are known as Ecovillages. They demonstrate their impact on the community and the energy consumption. Ecovillages have evolved into ecocities of the future, most of them not completed yet or in design phase. For both groups (ecovillages and ecocities) tables of matrixes are constructed in order to better understand their potential and functionality, and their special features and characteristics. This chapter is in search of analyzing the eco-potential and renewable energies for further development of future cities, considering ten case studies all over the world and ending with Tirana. The fossil fuel age is quickly coming to an end, so, the world must be prepared for the implementation strategies and utilization of renewable and alternative energies. (shrink)

This article examines how a non-anthropocentric virtue ethics can truly avoid an anthropocentric bias in the ethical evaluation of a situation where the environment is at stake. It argues that a non-anthropocentric virtue ethics capable of avoiding the pitfall of an anthropocentric bias can only conceive of the ultimate good—from which virtues are defined—in reference to an ecological self. Such a self implies that the natural environment is not simply a condition for human flourishing, or something that complements it (...) by adding the proper good of animals, organisms or ecosystems. Fulfilment is not that of a human self, but that of an ecological self: the natural environment or nature is not an external but an internal good. Therefore, the virtues or character traits that such an ecological self must nurture and develop leads us ultimately to distinguish—without opposing them—three different forms of virtue ethics applied to the environment, depending on whether it is anthropocentric or non-anthropocentric and whether nature is considered extrinsically or intrinsically. Such distinctions are also crucial to determine how we conceive of the political community and the collective goals that virtuous citizens assign to it (for instance, to preserve biodiversity, to tackle climate change, and so on).

Biological diversity would apparently seem the most intuitive and easily studied of all the ecological concepts. However, in practice biodiversity has suffered from great number of definitions that vary with the specific needs of the different researchers, thus making it extremely confusing as an ecological concept. In this paper, I shortly review the concept of biodiversity showing that there exists a substantial ambiguity among ecologists as far as biodiversity conceptualization and evaluation is concerned. I conclude that, (...) due to this major disagreement on its very nature, biodiversity may be defined simply as a set of multivariate summary statistics for quantifying different characteristics of community structure.

This article embarked on a critical evaluation of religious leadership and ecological consciousness in Africa, using the case of the Nigerian Christian religious community. The article argued that the concept of ecological justice lacks strong theological conceptualisation in the Nigerian ecclesiastical community. Therefore, Ime Okopido’s argument in favour of stewardship for the involvement of religious leadership in the pursuit of ecological and socioeconomic justice served as the starting point for this engagement. However, such engagement of the religious leadership and (...) of the faithful should include developing ecological theological concepts, such as value for community, which are relevant to the context and resonate with indigenous cultures. Embarking on ecological activism, a change of lifestyles and finding other concrete ways of protecting the environment and biodiversity could ameliorate the crisis of ecological and socio-economic injustice in Africa by promoting, in particular, the praxis of value for community.

Extinction is a concept of rapidly growing importance, with the world currently in the sixth mass extinction event and a biodiversity crisis. However, the concept of extinction has itself received surprisingly little attention from philosophers. I will first argue that in practice there is no single unified concept of extinction, but instead that its usage divides between descriptive, epistemic, and declarative concepts. I will then consider the epistemic challenges that arise in ascertaining whether a species has gone extinct, and (...) how these lead to serious limitations on responsibility and accountability for preventing extinctions. I will propose two conceptual engineering changes to our understanding of extinction. Firstly, to use twin epistemic concepts of extinction, corresponding to high and low epistemic demands. Secondly, to explicitly recognize that in many contexts extinction is a thick concept that contains an evaluative component, which therefore motivates explicit ethical considerations such as the use of precautionary principles.

Distinguishing between the source and the locus of value enables environmental philosophers to consider not only what is of value, but also to try to develop a conception of valuation that is itself ecological. Such a conception must address difficulties caused by the original locational metaphors in which the distinction is framed. This is done by reassessing two frequently employed models of valuation, perception and desire, and going on to show that a more adequate ecological understanding of valuation emerges when (...) these models are fully contextualized in the intersecting life worlds of the ecological community. Ecological evaluation takes place in ongoing encounters between these worlds and a crucial part in this process is assigned to living beings that are “open-endedly open,” that is, open not only to what the world affords them and others, but open to an indefinite field of possible valuational encounters between all kinds of beings. Ecological valuation overcomes some of the conceptual failings of contemporary attempts to evaluate nature: “The Economics of Ecology and Biodiversity” and “Valuing Nature.”. (shrink)

This book examines the link between population growth and environmental impact and explores the implications of this connection for the ethics of procreation. In light of climate change, species extinctions, and other looming environmental crises, Trevor Hedberg argues that we have a collective moral duty to halt population growth to prevent environmental harms from escalating. This book assesses a variety of policies that could help us meet this moral duty, confronts the conflict between protecting the welfare of future people and (...) upholding procreative freedom, evaluates the ethical dimensions of individual procreative decisions, and sketches the implications of population growth for issues like abortion and immigration. It is not a book of tidy solutions: Hedberg highlights some scenarios where nothing we can do will enable us to avoid treating some people unjustly. In such scenarios, the overall objective is to determine which of our available options will minimize the injustice that occurs. This book will be of great interest to those studying environmental ethics, environmental policy, climate change, sustainability, and population policy. (shrink)

The protection of species ranks highly among environmentalist priorities, and many environmentalists expect the public to respect and support efforts to protect and rehabilitate endangered species. There are a range of instrumental and anthropocentric justifications for these attitudes, yet some environmentalists want more. It is unclear that more is to be had. In particular, it is challenging to justify some environmentalist attitudes without appealing to some version of the claim that species are intrinsically valuable. However, this has been a notoriously (...) difficult thesis to defend, and it is clearly not available to those who doubt the existence of species. In this paper, I show how a number of environmentalist commitments that appear to be about the value of species can be interpreted and defended in a way that is compatible with antirealism about species. According to my proposal, the proper target of environmentalists’ evaluative concern is the irreplaceable design that is embodied by the individuals that make up a (putative) species. This approach can capture and justify many environmentalist attitudes about the value of biological variety without attributing intrinsic value to species, or even requiring a place for species in our ontology. This enables environmentalists to effectively sidestep a number of puzzling issues surrounding the nature and value of species. (shrink)

Air pollutants pose a threat to biodiversity throughout the world. This study was conducted to evaluate atmospheric element accumulation in Isparta city, including Gölcük Nature Park, located in the Western Mediterranean Region of Turkey. It is aimed to determine the air quality and potential pollutant sources in the region through lichen biomonitoring. Specimens of the epiphytic foliose lichen Physcia aipolia (Erh. ex Humb.) Fürnr. were sampled from 14 sites in the study area and analyzed by ICP-MS with reference material (...) in order to detect 11 trace elements; Al, As, Cd, Cr, Cu, Fe, Mn, Ni, Pb, V, and Zn. The spatial distribution of these airborne elements in the study area was mapped. The results showed that the elemental sequence in terms of average concentrations measured was as follows: Ni >Cr >V >Fe >As >Al >Zn >Cu> >Cd >Mn >Pb. The results of cluster analyses of the elemental data indicated that the 3 major contaminants in the urban area were Cr, Ni, and V, probably due to the extensive use of coal in heating facilities and gasoline in vehicles. P. aipolia specimens accumulated maximal concentrations of As, Cr, Fe, Ni, and V in the northern and the southeastern localities surrounding the city, while Cd, Pb were most abundant in the eastern edge of Gölcük Nature Park. The pollution in Isparta city with heavy metal is worse than expected, mostly due to the extensive use of coal as fossil fuel. In addition, it seems to be associated with the city's topographic and climatic characteristics, e.g. inversion effects. (shrink)

This paper puts Jane Bennett’s vital materialism into dialogue with Luce Irigaray’s ontology of sexuate difference. Together these thinkers challenge the image of dead or intrinsically inanimate matter that is bound up with both the instrumentalization of the earth and the disavowal of sexual difference and the maternal. In its place they seek to affirm a vital, generative materiality: an ‘active matter’ whose differential becomings no longer oppose activity to passivity, subject to object, or one body, self or entity to (...) its ‘other’. For both thinkers, displacing the hylomorphic conceptual structures that have tended to dominate western metaphysical thought is inseparable from critiquing the model of the individual subject as bounded, autonomous and self-identical. Such individualism is countered by the relational ontologies figured in Bennett’s ‘distributed agencies’ and Irigaray’s ‘placental economy’, and by a shared attentiveness to the capacities of the human body to bear others within. Nonetheless, this paper argues that each thinker renders this ‘other within’ in very different ways. On the one hand, Bennett’s approach complements and expands Irigaray’s notion of the elemental by affording a greater attentiveness to inorganic and non-sexuate matters. On the other, Irigaray’s conception of generative relationality and the ontological priority of the in-between allows us to think such material entanglements in ways that more fully displace the twinned logics of individualism and instrumentalization. Her project thereby affirms the relational and irreducible differences on which the ‘vitality’ of a vital materiality depends. If there is no more “earth” to press down/repress, to work, to represent, but also and always to desire, no opaque matter which in theory does not know herself, then what pedestal remains for the ex-sistence of the “subject”? If the earth turned and more especially turned upon herself, the erection of the subject might thereby be disconcerted and risk losing its elevation and penetration. For what would there be to rise up from and exercise his power over? And in? Irigaray, Speculum of the Other Woman Jane Bennett has recently argued that “the image of dead or thoroughly instrumentalized matter feeds human hubris and our earth-destroying fantasies of conquest and consumption”, continuing that: “The figure of an intrinsically inanimate matter may be one of the impediments to the emergence of more ecological and more materially sustainable modes of production and consumption”.11J. Bennett, Vibrant Matter: A Political Ecology of Things, Durham and London: Duke University Press, 2010, ix. Henceforth VM. View all notes This insight is prefigured and re-affirmed by the work of Irigaray. Her sustained analysis of western thought and culture shows how its constitutive disavowal of sexual difference and the maternal is inextricably bound up with an equally deep-rooted disavowal of matter and corporeality. As the above passage from Speculum suggests,22L. Irigaray, Speculum of the Other Woman, trans. G. Gill, Ithaca: Cornell University Press, 1985, 133. Henceforth S. View all notes Irigaray seeks to expose woman's reduction to an object for a subject and a maternal-material resource for man's speculations; but in disentangling woman from her symbolic identification with the earth, she also seeks to release the earth from its identification with a passive and manipulable matter. Her work thus bears directly on the revaluation required to transform human beings' relations to materiality: both their own, and that of the earth they inhabit. At the centre of this revaluation is Irigaray's work to displace the image of dead or intrinsically inanimate matter that Bennett also critiques, and to affirm instead a sexuate materiality that is both living and generative. Her consistent troubling of hylomorphism is as unsettling for the subject as her question: “But what if the ‘object’ started to speak?” This question is echoed in Bennett's concern with “the moment when the object becomes the Other, when the sardine can looks back, when the mute idol speaks”.33 VM, 2, citing W.J.T. Mitchell, What Do Pictures Want?, Chicago, Chicago University Press, 2005, 157. View all notes As this passage indicates, Bennett's own project is more concerned with the agency of non-human materialities – including their role in the constitution of the human – than with specifically sexed bodies or a materiality inflected by sexual difference. It is these crucial differences in emphasis, I will suggest, that allow the work of these two thinkers to be brought together in productive dialogue. On the one hand, Bennett's approach affords a greater attentiveness to inorganic and non-sexuate matter; on the other, Irigaray's twinned ontology of sexual difference and maternal relation is better able to affirm the relational differences on which the “vitality” of a vital materiality depends. The paper begins by outlining several key elements of Irigaray's philosophy of sexual difference to show how it leads necessarily to a rethinking of matter. This rethinking is especially helpful for shifting away from the hylomorphism that has been a dominant strand in western thought, informing an understanding of the earth as a fundamentally inert and ever-ready resource. As I will show, the figures through which Irigaray re-articulates female specificity also allow her to refigure the earth as active matter that “turns upon herself ” in generative flux. In the second section, I will situate Irigaray's re-thinking of matter in relation to Bennett's “vital materiality”.44Bennett can be aligned with a number of thinkers who have come to be grouped under the heading “new materialisms”. See S. Alaimo and S. Hekman, eds., Material Feminisms, Bloomington & Indianapolis: Indiana University Press, 2008; D. Coole and S. Frost, eds., New Materialisms: Ontology, Agency, and Politics, Durham and London: Duke University Press, 2010. View all notes An advantage of this concept is that it refuses the separation between humans and matter still implicit in concepts such as “the environment”. By attending to “our own constitution as vital materiality”, as well as the ways our “own” bodies are never “fully or exclusively human”, Bennett adjusts the status of human actants while re-evaluating non-human bodies “as actants rather than as objects”. As I will show, her approach provides a constructive critical perspective on Irigaray's work by drawing attention to the specifically non-sexuate nature of the elemental. Equally, however, Irigaray's insistence on sexuate difference problematises any appeal to a generic notion of “the human”. This is especially helpful, I will suggest, in relation to contemporary descriptions of climate change as “anthropogenic”. By homogenising human beings, such descriptions make it more difficult to address the ways in which current ecological problems are inseparable from global patterns of social, political and economic inequity. For both thinkers, challenging hylomorphism needs to be matched with a critique of the dominant modern model of the subject as bounded, autonomous and self-identical. And for both, this model is displaced and undone by the capacity of the human body to bear others within, in ways that engender and sustain human life. Yet as I will discuss in the final two sections, each thinker renders this “other within” in very different ways, with significant implications for the ethics and politics of a “vital materiality”. In the end it is Irigaray's rendering of a distinctively female capacity to bear an other within, explored via the generative relationality of a placental economy, that more fully escapes the individualism of the One and the Same. Together, Irigaray and Bennett show that to take seriously the ecological crises that currently confront us means overcoming the disavowal of both human beings' own fundamental materiality and our dependency on the sustaining materialities of the earth. In contrast, a dominant strand in contemporary responses to these crises is an environmental politics of “enlightened self-interest”55I borrow this phrase from H. Kopnina's critical discussion in “Forsaking Nature? Contesting ‘Biodiversity’ Through Competing Discourses of Sustainability”, Journal of Education for Sustainable Development 7, no. 1 : 51–63. that precludes any serious re-evaluation of human beings' relations to matter and the earth. If human beings can be persuaded that current levels of environmental degradation are damaging to them, threatening perhaps their very survival, they are more likely to take decisive steps to alter their behaviour. Insofar as such approaches demand action only for the sake of human interests and ends, they are both anthropocentric and spring from the same instrumentalising rationality that has engendered the ecological crises we currently face. They may well be successful in prompting action. But by foregrounding the survival of “the human species” per se, such approaches foreclose discussion of whose interests are served if survival is all that is allowed to be at stake, and whose lives are thereby consigned to ongoing exploitation. Moreover, as I will argue below, the instrumental rationality that serves survival is at odds with an affirmation of life, as a becoming that depends on difference. With this in mind, I will problematise Bennett's proposed politics of “expanded self-interest”, while seeking to retain many of the insights her approach brings. To more fully displace the “rational” self-interest that has encouraged human exploitation of the earth, we might take up Bennett's “vital materiality” in ways informed by Irigaray's conception of generative difference and the relational space-time of the in-between.

The terms used to describe and negotiate environmental quality are both ambiguous and value-laden. Stakeholders intimately and actively involved in the management of forested lands were interviewed and found to use ambiguous, tautological, and value-laden definitions of terms such as health, biodiversity, sustainability, and naturalness. This confusing language hinders public participation efforts and produces calls to regulate and remove discretion from environmental professionals. Our data come from in-depth interviews with environmental management professionals and other stakeholders heavily vested In negotiating (...) the fate of forested lands. We contend that environmental science and management will be more effective if its practitioners embrace and make explicit these ambiguous and evaluative qualities rather than ignore and disguise them.

Heterogeneous beliefs and decision processes generate positive externalities for social and economic systems, analogous to biodiversity in biological systems. Although some aspects of biodiversity (e.g., pests, parasites and bacteria) can lead to ecological and economic problems, biodiversity provides flows of beneficial ecological services and is widely regarded as a valuable natural resource and informational asset, whose value increases as we learn more and science progresses (Wilson in Bioscience 35(11):700–706, 1985). Heterogeneous beliefs and decision processes (and heterogeneous behaviors (...) they generate) similarly provide flows of beneficial economic services. Behavioral diversity should therefore be seen as a natural resource and informational asset likely to improve human wellbeing in surprising ways in the future. Paternalistic policies motivated by the goal of “correcting” allegedly suboptimal beliefs and behavior that diverge from expert recommendations jeopardize behavioral diversity at a substantial cost to social welfare. The risk of encroaching on this beneficial behavioral heterogeneity with policies that aim to induce behavioral and belief monocultures should be included explicitly as costs when evaluating nudges and other paternalistic policies.

In common with much of the Western world, agrarianism—valuing farmers and agricultural activity as intrinsically worthwhile, noble, and contributing to the strength of the national character—runs through Australian culture and politics. Agrarian sentiments and attitudes have been identified through empirical research and by inference from analysis of political debate, policy content, and studies of media and popular culture. Empirical studies have, however, been largely confined to the US, with little in the way of recent re-evaluations of, or developments from, early (...) work. This paper reports on research that seeks quantitative empirical evidence for the existence of agrarianism in the Australian community and seeks to identify its core characteristics. Using a purpose-designed sub-set of items within a large, omnibus-style survey of regional and rural Australia, we demonstrate that agrarianism exists as a scientifically quantifiable concept identifiable through responses to four key propositions: that Australians should support policies aimed at improving the position of the agricultural industries; that working in agriculture and associated industries brings out the best in people; that agricultural producers make a major contribution to environmental protection and biodiversity conservation; and that the development of agriculture in Australia contributed to the development of the national character. We found very little variation in the degree to which different demographic groupings agree with agrarianism. Older people, farmers, and non-Indigenous Australian-born respondents were among those who were statistically significantly more likely to agree with the defining propositions of agrarianism, but their scores were only very slightly higher than those of other sub-populations in the sample.

We uncover a largely unnoticed and unaddressed problem in conservation research: arguments built within studies are sometimes defective in more fundamental and specific ways than appreciated, because they misrelate values and empirical matters. We call this the unraveled rope problem because just as strands of rope must be properly and intricately wound with each other so the rope supports its load, empirical aspects and value aspects of an argument must be related intricately and properly if the argument is to objectively (...) support its conclusion. By characterizing this problem with precision, our study differs from but complements existing studies of value issues in conservation science, in two ways. First, it focuses on key relationships between empirical issues and value issues, relations that have sometimes been obscured by focusing on these issues more independently of each other. Second, it focuses on these relationships within arguments and deploys a method of argument analysis and evaluation honed in other fields but under-utilized in conservation science. By combining our study's novel features, we detail six families of argument defect that exemplify the unraveled rope problem within existing literature. These defects sometimes manifest within basic research stages, rather than just in more applied downstream stages where roles for values are already obvious to many. As scientific reasoning and communication become increasingly important for addressing society's greatest environmental challenges, overcoming the unraveled rope problem will be essential to the success and integrity of conservation research. Therefore, we also outline potential solutions, preventative measures, and useful further work for conservation researchers. (shrink)

This paper is motivated by the observation that Southern governments start to take responsibility for a more sustainable production of agricultural commodities as a response to earlier private initiatives by businesses and non-governmental organizations. Indonesia is one of the leading countries in this respect, with new public sustainability regulations on coffee, cocoa and palm oil. Based on the concept of governance capacity, the paper develops an evaluation tool to answer the question whether the new public regulation on sustainable palm (...) oil may become a viable alternative to private regulation. ISPO embraces a tremendous governance challenge as thousands of companies and millions of smallholder farmers are expected to participate. It is concluded that, although ISPO has initiated a process of change, it has not yet developed its full potential. The main reason regards ISPO’s rather loose problem definition, weak authority of the implementing organization, and the fact that the reliability of ISPO is still too low to convince of the global market. ISPO may therefore face difficulties in meeting its own targets and solving palm-oil related problems, such as deforestation, biodiversity loss, greenhouse gas emissions, and social conflicts between big plantations and local communities. The main governance challenge regards combining a more authoritative implementation mechanism with a convincing balance between sustainability objectives and economic interests of the sector.

In lieu of an abstract, here is a brief excerpt of the content:Prelude to Tackling Contemporary Crises: William James and a Psychological Springboard to Political ChangePaul Croce (bio)“That selective industry of the mind,... incessantly deciding, among many things,... which ones for it shall be realities.”—William James, 1892 (PBC, 167)“[N]either the whole of truth, nor the whole of good, is revealed to any single observer.”—William James, 1899 (TT, 149)The modern world has witnessed tremendous increases in prosperity, and that material abundance has (...) spurred great achievements. But these successes have also brought enormous and troubling side effects. Climate change, biodiversity loss, social inequality, and more problems have grown into crises with potential to challenge the achievements themselves. Alongside these challenges, many outstanding proposals have also emerged for dealing with our present crises. The crises and the insights for addressing them are in a harrowing competition, reminiscent of what H. G. Wells called “a race between education and catastrophe.” During recent chapters of this contest, especially in the United States, sound suggestions for halting or reversing environmental deterioration and for reducing class and racial inequities have gained some public and political support but have also met considerable resistance.1 While direct work to [End Page 26] address the crises is important, those efforts can be supported with understanding of the people and ideologies resisting that work. In fact, neglect of these impediments, which can further enable them to reduce abilities or willingness to address problems or even notice them, may be the biggest crisis of all.Just as medication can directly heal an illness while rest and self-care can build up general strength to support recovery, so coping with crises calls for both grappling with them directly and also consideration of the impediments that reduce the strength of those steps toward social healing. The inquiry here serves as a complement to sound proposals for immediate action by diagnosing what has hindered their realization. Outcries against injustice and creative interventions address the acute conditions of current crises, while cultural assessments of ways those responses gain or lose attention serve as prescriptions for addressing the chronic conditions that have exacerbated the crises through distraction. As with medical issues, long-term and preventive care of chronic problems can support acute treatment, even as they do not displace the need for immediate action.This article confronts a puzzle about why so many people do not pay attention to such large problems in nature and society and what steps can be taken to bridge that divide between the committed and the distracted. The emphasis here on attention shifts focus away from ideological differences and toward the values selections that drive the ideological differences. This article portrays James’s own path as he learned from differences before explaining how his theories offer insights on how selective choices shape the assumptions supporting ideologies that so often form into hostile contrasts.2 In addition to these alerts about the challenges of disagreement, he also presents methods to encourage listening across differences for chances to turn some of those commitments into constructive possibilities rather than treating them as reasons [End Page 27] to fight. These ways to evaluate cultural and political debates and increase understanding about selective choices can shed light on how so many people have been unwilling or unable to pay attention to the mounting problems, and through encouragement of more listening with respect, these methods can encourage more support for addressing the crises themselves.I. Jamesian Ways to Listen Across DifferencesCharles Taylor calls William James (1842–1910) “our great philosopher of the cusp.” This brief, elegant expression depicts a borderland thinker adept at mediating contrasting ideas. James’s often-difficult experiences in development toward that way of thinking and that reputation provide more depth about the contrasts that he experienced on the way toward his creative syntheses in psychology and philosophy.3 His wrestling with different interpretations serves as a microcosm for the challenges and rewards of listening for potential insights on each side of even hostile contrasts. He designed deliberate ways to reckon with differences, considering each to be a partial yet valuable window into the human condition. In his youth, he was torn between the competing perspectives of religious thought... (shrink)

Oases have served as sacred landscapes and sources of ritual plants in arid regions of the Old and New Worlds. We evaluate the Jesuit mission oases of the Baja California peninsula for their role in agrobiodiversity persistence, and extend theories of sacred landscapes and biodiversity conservation to agricultural species and practices. Jesuit missionaries on the peninsula introduced a suite of crops species and agricultural and water management systems that persist in the oases and have become an integral part of (...) the cultural and religious identity of the peninsula. The sacred landscapes of the oases are defined by elements of the Jesuit mission systems, such as water capture systems and irrigation canals, stone field borders and terraces, field gardens or huertas, groves of olive trees and date palms, and multi-tiered agroecosystems. Sacred practices—including pilgrimages, religious rites, and Catholic-based community celebrations—depend on the integrated “landscapes” of the oases and on the ritual use of wild and cultivated oasis plant species. We propose that some, though not all, of the peninsula oases may be considered as sacred landscapes responsible for maintaining heritage crop species, biodiversity, and traditional farming and foodways practices.

Agroecological farming is widely considered to reconcile improved working and living conditions of farmers while promoting social, economic, and ecological sustainability. However, most existing research primarily focuses on relatively narrow trade-offs between workload, economic and ecological outcomes at farm level and overlooks the critical role of contextual factors. This article conducts a critical literature review on the complex nature of agroecological farm work and proposes the holistic concept of sustainable farm work (SFW) in agroecology together with a heuristic evaluation (...) framework. The latter was applied to ten case studies to test its relevance, affirming positive outcomes of agroecology on SFW, such as improved food sovereignty, biodiversity conservation, and social inclusiveness, but also showing trade-offs, including increased workload and potential yield reductions. Further, results show that contextual factors, such as policy support, market regulation, and access to resources, heavily influence the impact of agroecological practices on SFW. This article strongly argues for the importance of a holistic understanding of SFW and its contextualization within multiple socio-ecological system levels. The proposed framework establishes clear relationships between agroecology and SFW. An explicit recognition of these multidimensional relationships is essential for maximizing positive outcomes of agroecology in different contexts and fostering SFW. On a theoretical level, this research concludes that, from a holistic perspective, work is an entry point to studying the potential of agroecology to drive a sustainable agroecological transition in economic, social, and ecological terms.

Communities, policy actors and conservationists benefit from understanding what institutions and land management regimes promote ecosystem services like carbon sequestration and biodiversity conservation. However, the definition of success depends on local conditions. Forests’ potential carbon stock, biodiversity, and rate of recovery following disturbance are known to vary with a broad suite of factors including temperature, precipitation, seasonality, species’ traits and land use history. Methods like forest changes over time , and comparison with 'pristine' reference forests have been proposed (...) to compare the structure and biodiversity of forests in the face of underlying differences. However, data from previous visits or reference forests may be unavailable or costly to obtain. Here, we introduce a new metric of locally weighted forest inter-comparison to mitigate the above shortcomings. This method is applied to an international database of nearly 300 community forests, and compared with previously published techniques. It is particularly suited to large databases where forests may be compared among one another. Further, it avoids problematic comparisons with old-growth forests which may not resemble the goal of forest management. In most cases, the different methods produce broadly congruent results, suggesting that researchers have the flexibility to compare forest conditions using whatever type of data is available. Forest structure and biodiversity are shown to be independently measurable axes of forest condition, although users’ and foresters’ estimations of seemingly unrelated attributes are highly correlated, perhaps reflecting an underlying sentiment about forest condition. These findings contribute new tools for large-scale analysis of ecosystem condition and natural resource policy assessment. Although applied here to forestry, these techniques have broader applications to classification and evaluation problems using crowdsourced or repurposed data for which baselines or external validations are not available.

Although there exists a strong uncertainty surrounding the evaluation of the decline of biodiversity, and a larger uncertainty still regarding projections of the decline to come, there is no controversy on the fact that the current rate of extinction is in a crisis. The fact that this decline is above all of anthropic origin is the object of a consensus within the scientific community. This text thus takes as a starting point the existence of a true crisis of (...) biodiversity. This crisis of biodiversity must conclude in the adoption of a principle of protection of the biodiversity, a normative principle which would constrain the relation of man with nature with regard to its diversity. I will show in this text that the principle of sustainable development is not sufficient to adequately define a principle of protection of the biodiversity. (shrink)

This paper reports on the long-term effectiveness of a non-formal co-curricular educational program based on a campus ecogarden at a Hong Kong university in developing pro-sustainability awareness, attitudes and behavior among undergraduate students. This service-based, nature-based experiential learning program, termed the Ecogarden Farmer and Biodiversity Surveyor, has been running at the university since 2015. The program is divided into two consecutive phases: a training phase comprising various learning activities and a successive internship phase consisting of the all-round practical tasks (...) involved in managing the garden. A retrospective evaluation of the program using phenomenographic approach and content analysis was adopted to reveal the diversity of students’ learning experience, as the indicators of the success of the program. Of 112 participants from 4 cohorts, 32 completed online questionnaires, and semi-structured interviews were successfully conducted with twelve participants, three from each of the four cohorts. The results indicated that the program’s outcomes could be categorized into five themes. Most outcomes fit into the theme ‘an increase in knowledge and skill level,’ followed by ‘rise in environmental awareness,’‘facilitation of personal growth,’ and ‘enhancement of career development.’ Many structural experiences revealed may suggest the success of the program. The longer the participants had participated in the program, the more in-depth and diversified reflection of the senior participants relating to personal development were mentioned. This study provides critical insights into the validity of retrospective program evaluation for assessing the long-term impact of EfS programs by introducing a cross-sectional study of different cohorts as a serial time-point sampling strategy.

Control of wild animals may give rise to controversy, as is seen in the case of badger control to manage TB in cattle in the UK. However, it is striking that concerns about the potential suffering of the affected animals themselves are often given little attention or completely ignored in policies aimed at dealing with wild animals. McCulloch and Reiss argue that this could be remedied by means of a “mandatory application of formal and systematic Animal Welfare Impact Assessment ”. (...) Optimistically, they consider that an AWIA could help to resolve controversies involving wild animals. The aim of this paper is to evaluate the potential of AWIA. We begin by showing how ideas akin to AWIA already play a significant role in other animal ethics controversies, particularly those concerning laboratory animal use and livestock production; and we bring in lessons learnt from these controversies. Then we comment on the suggested development and application of AWIA in the case of badger control. Finally, we discuss the prospects of applying AWIA to other sorts of wild animal controversy. We argue that the AIWA, as developed by McCulloch and Reiss, relies on several dubious premises, including that killing is a welfare issue. Furthermore, we argue that AWIA is unlikely to prevent serious moral disagreements over how to weigh concerns about wild animals against priorities in human health, the health of domestic and farm animals, and biodiversity, but that it may nonetheless serve to limit harms imposed on the wild animals.

A number of areas of biology raise questions about what is of value in the natural environment and how we ought to behave towards it: conservation biology, environmental science, and ecology, to name a few. Based on my experience teaching students from these and similar majors, I argue that the field of environmental ethics has much to teach these students. They come to me with pent-up questions and a feeling that more is needed to fully engage in their subjects, and (...) I believe some exposure to environmental ethics can help focus their interests and goals. I identify three primary areas in which environmental ethics can con- tribute to their education. The first is an examination of who (or what) should be considered to be part of our moral community (i.e., the community to whom we owe direct duties). Is it humans only? Or does it include all sentient life? Or all life? Or ecosystems considered holistically? Often, readings implicitly assume one or more of these answers; the goal is to make the student more sensitive to these implicit claims and to get them to think about the different reasons that support them. The second area, related to the first, is the application of the different answers concerning the extent of the ethical community to real environmental issues and problems. Students need to be aware of how the different answers concerning the moral community can imply conflicting answers for how we should act in certain cases and to think about ways to move toward conflict resolution. The third area in which environmental ethics can contribute is a more conceptual one, focusing on central concepts such as biodiversity, sustainability, species, and ecosystems. Exploring and evaluating various meanings of these terms will make students more reflective and thoughtful citizens and biologists, sensitive to the implications that different conceptual choices make.

Nowadays, that part of Amazonia which is situated on Brazilian territory is more and more the focus of attention for communication methods and the international agenda. This enormous expanse of land covered by tropical forest of unequalled beauty, extending over several Brazilian states, possesses an extremely rich biodiversity, with a vast potential reserve of natural resources of all sorts, and inspires admiration as well as inevitable greed. The intensification of human activity in the region has given rise to problems (...) such as deforestation and a resulting loss of organic matter whose importance has yet to be properly evaluated; it has also led to conflict between the different local groups, such as the indigenous population, gold prospectors and the big landowners, and to the degradation of quite extensive areas, thus provoking questions on how best to promote sustained development in the region.
