Why conserve biodiversity? A multi-national exploration of stakeholders’ views on the arguments for biodiversity conservation

Given the concern about biodiversity loss, there are a number of arguments used for biodiversity conservation ranging from those emphasising the intrinsic value of biodiversity to those on the direct use value of ecosystems. Yet arguing the case for biodiversity conservation effectively requires an understanding of why people value biodiversity. We used Q methodology to explore and understand how different conservation practitioners (social and natural science researchers, environmental non-Governmental organisations and decision-makers) in nine European countries argue for conservation. We found that there was a plurality of views about biodiversity and its conservation. A moral argument and some arguments around the intrinsic and ecological value of biodiversity were held by all stakeholder groups. They also shared the view that species valuation does not justify the destruction of nature. However, there were also some differences within and between the groups, which primarily reflected the espousal of either ecocentric or anthropocentric viewpoints. Our findings suggest that moral arguments and those around biodiversity’s intrinsic and ecological value could potentially serve as a starting point for building consensus among conservation practitioners.     

Intrinsic values in nature: Objective good or simply half of an unhelpful dichotomy?

Two generations of conservationists and philosophers have built a strong case for intrinsic values in nature; they are the basis of the normative postulates of conservation biology. I argue that the recognition of intrinsic natural value is a fundamental and non-negotiable aspect of an eco-evolutionary worldview. Recently, relational values, “preferences, principles, and virtues associated with relationships”, have been proposed as a third category of values in nature, which may help to resolve the debate between instrumental and intrinsic valuation. By depicting intrinsic values as part of an unhelpful dichotomy between anthropocentric and ecocentric values, the current assessment of relational values fails to adequately account for the modern philosophical view of intrinsic natural value. The recognition of intrinsic natural value is not merely an academic exercise, but rather a vital aspect of conservation of the biosphere; recognition of value entails the obligation to do what is right, i.e., protect the good. Any attempt to reframe the discussion about values and environmental protection through more formal recognition of relational values will need to more clearly address how relational and intrinsic values coexist and how they can jointly form the basis for nature conservation.     

“If we work in conservation, money will flow our way”: hegemony and duplicity on the Coast of Oaxaca, Mexico

Conservation is the “common discursive framework” through which any meaningful action takes place within a strip of land on the Coast of Oaxaca. What is meant by it is a contested process of class struggle given the strength of regional transformations since 1990. Spearheaded by the tourist industry, conservation is a hegemonic game of duplicity. This article discusses how this is a successful case of “neoliberal conservation” and provides an ideological analysis of such a consensus.     

Common knowledge promotes cooperation in the threshold public goods game by reducing uncertainty

Recent work suggests that an important cognitive mechanism promoting coordination is common knowledge—a heuristic for representing recursive mental states. Yet, we know little about how common knowledge promotes coordination. We propose that common knowledge increases coordination by reducing uncertainty about others' cooperative behavior. We examine how common knowledge increases cooperation in the context of a threshold public goods game, a public good game in which a minimum level of contribution—a threshold—is required. Across three preregistered studies (N = 5580), we explored how varying (1) the information participants had regarding what their group members knew about the threshold and (2) the threshold level affected contributions. We found that participants were more likely to contribute to the public good when there was common knowledge of the threshold than private knowledge. Participants' predictions about the number of group members contributing to the public good and their certainty ratings of those predictions mediated the effect of information condition on contributions. Our results suggest that common knowledge of the threshold increases public good contributions by reducing uncertainty around other people's cooperative behavior. These findings point to the influential role of common knowledge in helping to solve large-scale cooperation problems.     

The need for speed: informed land acquisitions for conservation in a dynamic property market

Land acquisition is a common approach to biodiversity conservation but is typically subject to property availability on the public market. Consequently, conservation plans are often unable to be implemented as intended. When properties come on the market, conservation agencies must make a choice: purchase immediately, often without a detailed knowledge of its biodiversity value; survey the parcel and accept the risk that it may be removed from the market during this process; or not purchase and hope a better parcel comes on the market at a later date. We describe both an optimal method, using stochastic dynamic programming, and a simple rule of thumb for making such decisions. The solutions to this problem illustrate how optimal conservation is necessarily dynamic and requires explicit consideration of both the time period allowed for implementation and the availability of properties.     

Participatory Resource Monitoring as a Means for Promoting Social Change in Yunnan,China

Recent international forest policies stimulate involvement of communities in forest management as a strategy to improve biodiversity conservation and the quality of local livelihoods. Increasingly, the role of local people in monitoring forest resources is also acknowledged. This paper presents a participatory resources monitoring (PRM) system developed and implemented by representatives of 12 villages, six each within and adjacent to two nature reserves in Yunnan, China. The short-term objectives are to monitor resource and wildlife abundance, resource use, wildlife damage to crops, and land use. Main methods used by the village monitoring team are: (1) observation through forest walk, (2) village interview, and (3) market survey. Monitoring is implemented throughout the year to fit in the daily work of villagers. Staff from the nature reserve or forestry bureau provide support by visiting the villages several days per year. Results indicate that participatory monitoring is a valuable tool for villagers to engage in self-owned management actions. We discuss how monitoring is also a process which could lead to social change. Based on narratives we suggest that participatory monitoring builds trust between stakeholders, changes perceptions and attitudes and leads to more democratic and transparent decision-making. In discussing accuracy, we argue that all stakeholders perceive and interpret nature differently based on different worldviews, knowledge systems, values and beliefs. We argue that if participatory monitoring is to be sustainable, community-based monitoring – preferably linked to scientific monitoring and patrolling – should be designed as a discursive institution where the process of building social capital and inter-actor learning is extremely important. Finally, we briefly reflect upon efforts to scale up participatory monitoring.     

Does conservation on farmland contribute to halting the biodiversity decline?

Biodiversity continues to decline, despite the implementation of international conservation conventions and measures. To counteract biodiversity loss, it is pivotal to know how conservation actions affect biodiversity trends. Focussing on European farmland species, we review what is known about the impact of conservation initiatives on biodiversity. We argue that the effects of conservation are a function of conservation-induced ecological contrast, agricultural land-use intensity and landscape context. We find that, to date, only a few studies have linked local conservation effects to national biodiversity trends. It is therefore unknown how the extensive European agri-environmental budget for conservation on farmland contributes to the policy objectives to halt biodiversity decline. Based on this review, we identify new research directions addressing this important knowledge gap.     

Tiny terminological disagreements with far reaching consequences for global bird trends

Various combinations of data and expert opinion have been used to select species for indices of bird trends. Commonly these indices break species into groups based on their habitat preference such as woodland specialist, farmland specialist and generalist birds. It is unclear what influence differences in how species are allocated to these groups might have on trends in these indices. There is uncertainty surrounding reported trends in these bird groups with studies variously showing declines or increases in prevalence. This is usually attributed to ecological factors but if studies classify bird groups differently this variation may be due to inconsistency in classification. Disagreement about whether these bird groups are stable, increasing or declining has the potential to obscure important changes in bird prevalence and impede appropriate, timely conservation.We examined how consistently European and Australian researchers classified woodland, farmland and generalist birds, and whether this affected the trends in indices of these groups. Researchers from both regions classified species differently, and the population trends seen in these groups were strongly affected by differences in classification. While all classifications we studied suggest that populations are consistently declining for Australian woodland and European farmland birds and increasing for European woodland birds. European generalist and Australian farmland and generalist birds may be seen as increasing or decreasing in prevalence depending on classification.Our results question the current practice of idiosyncratically classifying indicators in scientific research and conservation. Current practice is making it more difficult to infer whether, when and how to preserve bird groups in Europe and Australia, potentially leading to sub-optimal biodiversity outcomes. We offer suggestions for building consensus on how to classify these bird groups in order to provide more reliable evidence to support conservation decisions.     

The rise of planning in nature conservation and the practitioners’ approach to conflicts. The inspiring case of the Northern French Alps nature reserves

This article examines how the rise of planning in conservation influences the conservation practitioners’ approach to conflicts in a region where protected areas have limited power. It is based on an analysis of the management plans of ten nature reserves of the Northern French Alps, complemented with interviews with the practitioners involved in elaborating these plans. It shows that the collaborative paradigm, predicated on the idea that deliberation between parties can lead to a shared understanding of the common good, has pervaded conservation planning. Collaborative planning enriches the planners’ view of the practices and values at work in the reserves. But it also encourages them to develop conflict avoiding strategies that contribute to maintaining existing power imbalances, which in such regions are often detrimental to conservation goals. Analysing the power relationships at play locally, encouraging the planners’ reflexivity, and increasing their agency would help realize the transformative potential of contentious situations.     

Toward ecologically scaled landscape indices

Nature conservation is increasingly based on a landscape approach rather than a species approach. Landscape planning that includes nature conservation goals requires integrated ecological tools. However, species differ widely in their response to landscape change. We propose a framework of ecologically scaled landscape indices that takes into account this variation. Our approach is based on a combination of field studies of spatially structured populations (metapopulations) and model simulations in artificial landscapes. From these, we seek generalities in the relationship among species features, landscape indices, and metapopulation viability. The concept of ecological species profiles is used to group species according to characteristics that are important in metapopulations' response to landscape change: individual area requirements as the dominant characteristic of extinction risk in landscape patches and dispersal distance as the main determinant of the ability to colonize patches. The ecological profiles and landscape indices are then integrated into two ecologically scaled landscape indices (ESLI): average patch carrying capacity and average patch connectivity. The field data show that the fraction of occupied habitat patches is correlated with the two ESLI. To put the ESLI into a perspective of metapopulation persistence, we determine the viability for six ecological profiles at different degrees of habitat fragmentation using a metapopulation model and computer-generated landscapes. The model results show that the fraction of occupied patches is a good indicator for metapopulation viability. We discuss how ecological profiles, ESLI, and the viability threshold can be applied for landscape planning and design in nature conservation.     

Reframing the conception of nature conservation management by transdisciplinary methodology: From stakeholders to stakesharers

Nature conservation is concerned with human–nature interface problems. The aim of this article is to examine how the transdisciplinary methodology can help improve community-based conservation approaches. Transdisciplinarity is an extremely promising global movement that promotes a new approach to the creation of human knowledge. It includes dialogue among the natural sciences, social sciences and humanities as well as with civil society, where the problems of the world are lived out on a daily basis. The intent of taking down the walls between the disciplines and civil society is to enable new types of knowledge to emerge through complex and integrated, mutually learned insights. The four pillars (axioms) of the transdisciplinary methodology – multiple levels of Reality (ontology), the logic of the included middle, emergent complexity (epistemology) and integral value constellations (axiology) – are explained as is the role each plays in reframing our conception of the conservation of nature. A transdisciplinary methodology helps everyone involved in a community-based conservational approach feel as if they are stakesharers rather than stakeholders. Almost everyone is familiar with the term stakeholder, referring to someone who can affect, or can be affected by others’, decisions. To have a stake in something means people share or have an involvement in it. We coined the term stakesharer to reflect the idea that, within transdisciplinary work, people share ideas, solutions, threats and opportunities as they try to stake out their collective response to human–nature interface problems.     

Do People Agree on What Makes One Feel Loved? A Cognitive Psychometric Approach to the Consensus on Felt Love

This pragmatic study examines love as a mode of communication. Our focus is on the receiver side: what makes an individual feel loved and how felt love is defined through daily interactions. Our aim is to explore everyday life scenarios in which people might experience love, and to consider people’s converging and diverging judgments about which scenarios indicate felt love. We apply a cognitive psychometric approach to quantify a receiver’s ability to detect, understand, and know that they are loved. Through crowd-sourcing, we surveyed lay participants about whether various scenarios were indicators of felt love. We thus quantify these responses to make inference about consensus judgments of felt love, measure individual levels of agreement with consensus, and assess individual response styles. More specifically, we (1) derive consensus judgments on felt love; (2) describe its characteristics in qualitative and quantitative terms, (3) explore individual differences in both (a) participant agreement with consensus, and (b) participant judgment when uncertain about shared knowledge, and (4) test whether individual differences can be meaningfully linked to explanatory variables. Results indicate that people converge towards a shared cognitive model of felt love. Conversely, respondents showed heterogeneity in knowledge of consensus, and in dealing with uncertainty. We found that, when facing uncertainty, female respondents and people in relationships more frequently judge scenarios as indicators of felt love. Moreover, respondents from smaller households tend to know more about consensus judgments of felt love, while respondents from larger households are more willing to guess when unsure of consensus.     

Looking under the bonnet of conservation conflicts: can neuroscience help?

Neuroscience—a branch of biology seemingly distant from nature/wildlife conservation is revolutionised by the ability to visualise the brain activity of humans. Using positron emission tomography (PET), functional magnetic resonance imaging (fMRI) and magnetoencephalograhy (MEG), neuroscience is revealing how humans are wired in ways that have bearing on any problem that involves values; and nature/wildlife conservation is surely one of those. Understanding how the human brain represents and processes morality and sacred values, and responds to conflicts could shed a powerful light on nature/wildlife conservation tactics. Conservation polices typically involve utilitarian considerations. However, research shows that conservation policies based solely on utilitarian considerations are likely to fail as the neurological process of rights and wrongs grates against the process of cost and benefits.     

Not null enough: pseudo-null hypotheses in community ecology and comparative psychology

We evaluate a common reasoning strategy used in community ecology and comparative psychology for selecting between competing hypotheses. This strategy labels one hypothesis as a “null” on the grounds of its simplicity and epistemically privileges it as accepted until rejected. We argue that this strategy is unjustified. The asymmetrical treatment of statistical null hypotheses is justified through the experimental and mathematical contexts in which they are used, but these contexts are missing in the case of the “pseudo-null hypotheses” found in our case studies. Moreover, statistical nulls are often not epistemically privileged in practice over their alternatives because failing to reject the null is usually a negative result about the alternative, experimental hypothesis. Scientists should eschew the appeal to pseudo-nulls. It is a rhetorical strategy that glosses over a commitment to valuing simplicity over other epistemic virtues in the name of good scientific and statistical methodology.     

Biodiversity hotspots through time: an introduction

International targets set for reducing the rate of biodiversity loss--the 2010 target--and ensuring environmental stability (Millennium Development Goals) have helped to focus the efforts of the scientific community on providing the data necessary for their implementation. The urgency of these goals, coupled with the increased rate of habitat alteration worldwide, has meant that actions have largely not taken into account the increasing body of data about the biodiversity change in the past. We know a lot about how our planet has been altered and recovered in the past, both in deep time and through prehistory. Linking this knowledge to conservation action has not been widely practised, by either the palaeoecology or the conservation communities. Long-term data, however, have much to offer current conservation practice, and in the papers for this volume we have tried to bring together a variety of different perspectives as to how this might happen in the most effective way. We also identify areas for productive collaboration and some key synergies for work in the near future to enable our knowledge of the past to be used for conservation action in the here and now. Lateral thinking, across knowledge systems and with open-mindness about bridging data gaps, will be necessary for our accumulating knowledge about our planet's past to be brought to bear on our attempts to conserve it in the future.     

Translation, Value, and Space: Theorizing an Ethnographic and Engaged Environmental Anthropology

In this article, I argue for placing the politics of translation and theories of value and spatial production at the center of environmental anthropology. For the past ten years, the Gimi-speaking peoples living in Maimafu village, Papua New Guinea, have taken part in an integrated conservation and development project attempting to foster a local system of valuing "nature" by tying biological diversity to economic markets through the creation of "eco-enterprises." However, the project fails to consider how Gimi produce, theorize, transmit, and express knowledge. Using ethnographic material concerned with hunting and song composition, I show that Gimi understand their forests to be part of a series of transactive dialectical relationships that work to produce identity and space. I also demonstrate that, as part of this project, Gimi social relations with their forests have been translated in ways that fit their beliefs into generic and easily understandable categories. This has been detrimental to the conservation project and it is politically problematic for an engaged environmental anthropology.     

Nature conservation from a Junior High School perspective

Nature conservation has a higher probability of being successful when it is backed by public support. This is influenced by knowledge and values, many of which may derive from school curricula, experiments and activities. We implemented a study in a Portuguese Junior High School aiming to evaluate: (1) which factors influence how people subscribe reasons for conserving nature; (2) the criteria used to identify conservation priority species; and, (3) the proposed recovery measures for priority species. A survey of 91 students in a suburban area revealed that nature conservation was regarded as being more important than tourism or industry, but less than values related to public health. Students who have close contacts with wildlife and whose parents have higher education levels exhibited positive attitudes towards nature conservation, which seems to derive from exposure to information related to nature, in their home environment. The criteria chosen to identify conservation priority species and to select appropriate conservation measures indicate that they are likely to be influenced by the media. These results emphasise that the relationship between parental education levels and access to information is an important factor in shaping urban students’ attitudes towards nature conservation.     

Ecosystem Services in Conservation Planning: Targeted Benefits vs. Co-Benefits or Costs?

There is growing support for characterizing ecosystem services in order to link conservation and human well-being. However, few studies have explicitly included ecosystem services within systematic conservation planning, and those that have follow two fundamentally different approaches: ecosystem services as intrinsically-important targeted benefits vs. substitutable co-benefits. We present a first comparison of these two approaches in a case study in the Central Interior of British Columbia. We calculated and mapped economic values for carbon storage, timber production, and recreational angling using a geographical information system (GIS). These 'marginal' values represent the difference in service-provision between conservation and managed forestry as land uses. We compared two approaches to including ecosystem services in the site-selection software Marxan: as Targeted Benefits, and as Co-Benefits/Costs (in Marxan's cost function); we also compared these approaches with a Hybrid approach (carbon and angling as targeted benefits, timber as an opportunity cost). For this analysis, the Co-Benefit/Cost approach yielded a less costly reserve network than the Hybrid approach (1.6% cheaper). Including timber harvest as an opportunity cost in the cost function resulted in a reserve network that achieved targets equivalently, but at 15% lower total cost. We found counter-intuitive results for conservation: conservation-compatible services (carbon, angling) were positively correlated with each other and biodiversity, whereas the conservation-incompatible service (timber) was negatively correlated with all other networks. Our findings suggest that including ecosystem services within a conservation plan may be most cost-effective when they are represented as substitutable co-benefits/costs, rather than as targeted benefits. By explicitly valuing the costs and benefits associated with services, we may be able to achieve meaningful biodiversity conservation at lower cost and with greater co-benefits.
