Species diversity has continuously been experiencing deterioration in the world that is widely connected with global trade. Previous studies have identified the impact of specific traded commodities on species diversity, but little evidence of causality from overall exports has been found. Using two-stage least-squares method with an instrument variable (IV-2SLS) and province-level panel data during 1978–2020, this paper explores the biological costs of international trade by investigating the impact of exports from China on domestic species diversity. We also examine the mechanisms through which exports affect species diversity and how heterogeneous factors cause differences on loss of species diversity. Results suggest that a 1% increase in export scale decreases species diversity by 2.28%. We also find that resource exploitation, infrastructure construction and land use are three major channels. Additionally, the provinces with more alien invasive species (over 450) or with higher dependence on exporting leather and textiles (over 16%) may suffer over 4% of species diversity loss per 1% of export scale. Moreover, the loss of plants is 2.43%, which is 0.83% higher than that of animals. Our transdisciplinary work is expected to be helpful for policy makers who pursue dual goals of export development and biodiversity protection. [ABSTRACT FROM AUTHOR]

The COP 15 of the UN Convention on Biological Diversity emphasised the need to monitor, evaluate, and disclose the risks and dependencies of financial institutions on biodiversity. In the light of this context, our paper focuses specifically on banks and is framed by the following overarching question: to what extent have banks identified, integrated, measured, and disclosed their dependency and exposure to ecosystem services (ES)? The literature on finance and biodiversity provides various arguments highlighting the urgency and significance of understanding and disclosing banks' ES risk exposure. Despite numerous public and/or private initiatives, banks have been slow to evaluate and integrate their dependency on ES, and related risks, into their operations and performance. Using data from the ten largest European banks, we estimate that for every dollar of equity holding, 26 cents are potentially exposed to high ES dependencies. This figure should be regarded as a lower estimate of the total banks' exposure to ES dependency. To make progress, we argue that banks must become champions of ES to ensure their own resilience and financial sustainability. Governance plays a key role, and we suggest several measures to accelerate this transition. [ABSTRACT FROM AUTHOR]

This paper models the effects of economic incentives on woodland planting on UK farmland, and the spatially-varying impacts on three avian species. The economic model uses an agent-based approach: "farmers" in each parcel compare economic returns from keeping their current agricultural land use with the economic incentive for woodland planting. An ecological model then predicts the effects of both parcel-level and local landscape-level woodland cover on species distributions. We compare results from two case study areas which vary in terms of the spatial correlation of opportunity costs and ecological potential. As the per-hectare value of the subsidy for woodland planting is increased, the values of our biodiversity indicator increase, but at rates which vary by case study area and by species. The cost-effectiveness of the economic instrument varies according to the sign of the spatial correlation between opportunity costs and ecological potential. [ABSTRACT FROM AUTHOR]

As a first step to assess the financial risks associated with biodiversity loss, this paper develops a method to evaluate the exposure of the financial system to biodiversity-related - physical or transition - shocks. We apply it to the security portfolio held by French financial institutions at the end of 2019. Employing the ENCORE database, we assess physical risks by examining how the firms that issued the securities in the portfolio depend on ecosystem services to produce. Our results indicate that they significantly depend on water-related ecosystem services and that 42% of the value of securities held by French financial institutions were issued by firms highly or very highly dependent on at least one ecosystem service. Using the Global Biodiversity Score tool, we assess transition risks by quantifying the biodiversity footprint of the security portfolio and of the firms that issued the securities. We find that the portfolio footprint is equivalent to the loss of 130,000km2 of pristine nature and that 38.5% of the portfolio value comes from firms belonging to sectors in the top 10% of biodiversity footprints. This offers new methodological tools to address the relationship between finance and biodiversity from a financial stability perspective. [ABSTRACT FROM AUTHOR]

This paper compares financial and biodiversity performance of small-scale shaded coffee and cocoa plantations versus intensified conventional ones. We conduct a meta-analysis including 23 studies on coffee and cocoa plantations over a 26 year period. Our results show that, contrary to common perceptions, profitability and cost-efficiency are higher for small-scale shaded systems. Despite the lower yields for shaded systems, the lower costs per area and higher price per kilogram of coffee or cocoa causes shaded systems to perform better financially. This finding shows that the traditional indicator ‘yield’ is an inaccurate measure of financial performance when studying diversified systems, and that the more detailed indicators as net revenue or benefit-cost ratio should be used instead. Few studies specifically reported on the relationship between biodiversity and financial performance, providing divergent results, yet various papers showed a promising optimum relationship for intermediate levels of shade. Because shaded systems are known to correlate positively with biodiversity, we postulate that they can offer competitive business opportunities for small-scale farmers, while also contributing to biodiversity conservation. Still, there is a pressing need for multidisciplinary studies to quantify financial and biodiversity performance simultaneously, and to identify opportunities for scaling up shaded systems.

One of the most important challenges of the 21st century is the quest for economic development models that respect the planet's ecosystem. Rather than imposing our industrial systems on nature, why not let nature influence our industrial and innovation systems? From wind turbine blades to bullet trains and solar cells, many of the technologies we rely on today have been inspired by solutions found in nature. Although relatively widespread in the fields of architecture and engineering, biomimicry/biomimetics remains largely overlooked in economics, public policy, and development studies. This is paradoxical because the world's remaining biodiversity stock-a knowledge bank of solutions to both current and unknown challenges- is largely held in developing economies and can be leveraged as a source of inspiration for -and entry door to- industrial innovation. This paper, therefore, investigates the relevance of biomimicry in the formulation of sustainable development strategies in biodiverse developing countries and maps out the national policy landscapes that can advance it. Several findings arise from this study. First, despite the exponential growth of biomimicry as a field and our understanding of its economic impact, what drives nature-inspired innovation remains elusive. Second, the biomimicry innovation landscape is dominated by industrialised economies that have relied on proactive policy interventions, while virtually no developing country has adopted biomimicry as an innovation strategy, consolidating the exploitation of the biodiversity in the developing world by firms in high-income nations. Third, by drawing on empirical evidence from a selection of Latin American countries, this paper shows that while biomimicry presents tremendous opportunities to leapfrog towards high value-added knowledge-intensive activities by using local biodiversity and related expertise as factor endowments, policy, and institutional factors have led to the persistence of important coordination failures that hinder the expansion and commercialization of biomimicry-based R&D. This paper concludes by discussing the public policies needed to support the integration of developing nations at the innovation frontier through biomimicry. [ABSTRACT FROM AUTHOR]

Ecological networks (ENs) aim to accommodate production and conservation within landscapes by shaping the spatial scope of conservation policies based on ecological criteria. The environmental effectiveness of these networks has been extensively studied; however, it has rarely been linked to their economic cost. This paper investigates whether EN-based spatial targeting relaxes the production-conservation trade-off and, if so, what the processes underlying its performance may be. We design an EN at the national level (France), with common farmland birds defined as a conservation goal and grassland expansion defined as a conservation lever. A dynamic, mechanistic, ecological-economic model simulates policy scenarios up to 2050 with alternative targeting strategies, including the EN. The results reveal that EN targeting is almost twice as cost-effective as a nationally homogeneous policy and about as cost-effective as focusing on biodiversity reservoirs, but with higher biodiversity gains. These outcomes rely on higher initial bird abundance in targeted regions, as well as positive feedback and spillover supported by bird dispersal. However, the EN's superiority only appears in the medium term because of ecological inertia. These interdisciplinary insights on a tool from ecology and conservation biology echo policy needs for the design and implementation of sustainable landscape management strategies. • Joint economic and ecological impacts of ecological networks (ENs) are poorly known • Ecological-economic modeling to evaluate EN-based conservation policies ex-ante • Spatiotemporally explicit simulations for bird conservation in France • EN doubles cost-effectiveness in the middle term compared to homogeneous policy • Dispersal generates benefits beyond intervention perimeter (biodiversity spillover) [ABSTRACT FROM AUTHOR]

This paper uses econometric analysis for understanding the determinants that affect the payment mechanism in material transfer agreements (MTAs). These contracts regulate the exchange of peculiar ecosystem services (genetic and biological materials) between a provider and a recipient of the service. The paper uses a set of “model” contracts from the late 2000s, gathered from the U.N. World Intellectual Property Organization (WIPO) and the Convention of Biological Diversity (CBD). Empirical results show that the probability that a payment scheme is included in the contract negatively depends on the presence of an acknowledgment obligation to the provider of the material. Probably aware of the complexity and uncertainty of the recipient's research activity, the provider (and the CBD) requires to be compensated through the recognition of his/her important input to the research venture. In economics, this can be interpreted as payment in terms of moral satisfaction. [ABSTRACT FROM AUTHOR]

The future of agriculture constitutes a major challenge to the achievement of sustainable development. There are new perspectives on greening (focusing on ecological objectives) and sustainability (combining both ecological and social goals). Academic papers mainly study the ecological efficiency of agricultural public policies, while real public policies, such as the European Common Agricultural Policy, examine both ecological and social considerations. The objective of this paper is to consider economic, social and ecological objectives within the design of agricultural public policies. Using a bio-economic model applied to France, we compare different optimal public strategies. We show that, when the biodiversity objectives are either very limited or very demanding, grassland subsidies are the best instruments from both green and sustainable points of view. However for medium objectives, reducing crops subsidies is the cheapest way to green the CAP, while subsidies on grasslands are the only strategy from a sustainability perspective. Our work highlights new trade-offs related to policy implementation, such as social acceptance or technical difficulties, and the spatial equity of performance among regions.

There are calls for social innovation to help with the effort to halt biodiversity loss. However, research on social innovation and biodiversity is dispersed and covers a multitude of disciplines. A systematic overview of research on social innovation and biodiversity is missing and this paper contributes by focusing on social innovation to tackle the drivers of biodiversity loss and unsustainability. The paper reviews research on social innovation in changing land use (agriculture, forestry, aquatic ecosystems and cities), in tackling exploitation of organisms (fishing, hunting, harvesting), and in addressing threats of climate change, pollution and invasive species. Across these drivers, we find a) a strong emphasis on social innovation as civic action for changing practices in addressing unsustainability, b) that social innovation research tends to focus on local experimentation although there are bodies of literature on policy-driven innovations and consumer/producer-driven innovations, and c) that there is very little research taking a critical perspective to explore negative or unintended consequences of social innovation. Drawing on the review, we propose three cross cutting issues that can be a focus for future research, practice and supportive policy: social innovation for nature-based solutions, social innovation for participatory governance, and social innovation for technology that tackles biodiversity loss. • Review covers social innovation tackling main drivers of biodiversity loss. • Social innovation for biodiversity focuses on civic action for changing practices. • Literature focuses on local experimentation with gaps on indigenous solutions. • Cross-cutting themes are nature-based solutions, technology and governance. • Transformation research needs a focus on social innovation and social exnovation.

Abstract: The assessment of total economic value has become a pragmatic and popular approach in nature valuation, yet criticisms have been raised. One major point of critique is that total economic value bases the monetary value of ecosystems purely on the flow of human benefits of services of ecosystems and consequently ignores questions of sustainable use of natural capital per se. This paper explains why total economic value by itself is in principle an inadequate concept to guide sustainable use of ecosystems and gives an overview of essential ecological theory that needs to be taken into account in addition to total economic value to fully include ecosystem sustainability. The paper concludes with a framework for combining ecological theory with economic valuation. The key elements here are theoretical ecological insights about ecosystem resilience and portfolio theory which offers an economic perspective on investment in biodiversity. Portfolio theory puts total economic value in a framework where investment in biodiversity is expanded to cover functional diversity and mobile link species in order to maintain ecosystem resilience and so fosters sustainable use of ecosystems.

Biodiversity offsetting (BO) claims to slow down biodiversity loss caused by development projects by generating ecological gains mainly through restoration activities conducted on land acquired to this effect. This leads to social conflicts around accessing land, especially with farmers and other land-users. The purpose of this paper is to analyze the opportunities and challenges of implementing BO by involving farmers through contracts akin to agri-environmental or stewardship schemes to produce ecological gains. We call them Agri-environmental Biodiversity Offsets Schemes (ABOS) and conduct an empirical analysis of a large ABOS program implemented for a new railway line in Southern France. We examine the effectiveness of ABOS through a survey carried out with 145 farmers and find that the main determinants of ABOS acceptability are: i) socio-economic factors, ii) social norms, iii) trust with contracting institutions, and iv) ease of integration in farm activities. Although ABOS allow developers to meet their legal requirements, major concerns are raised about additionality , especially through the manifestation of windfall effects, long-term permanence , and non-compliance with contract requirements. We conclude with policy recommendations and research perspectives to improve the implementation of ABOS for both nature and people. [ABSTRACT FROM AUTHOR]

Abstract As a semi-natural ecosystem, the agroecosystem is both a major provider and a major beneficiary of ecosystem services (ES). The aim of this paper was to contribute to the scientific understanding of the current status of AES research, recognize the knowledge base and influential articles, and uncover the key research themes and how the research themes have evolved over the past decade. Bibliometric methods based on the ISI Web of Science (WoS) database were used to analyse articles related to AES published between 2008 and 2017. A total of 3573 records were evaluated during this study. The results show that there has been a significant increase in research interest in the AES field. The most frequent keywords were "Biodiversity", "Land use change" and "Climate change". This study divides the common keywords into 7 categories and analyses them over two periods. Agrobiodiversity and land use have been emphasized in current AES research, which is a trend that will likely continue in the future. Valuation is indispensable, but AES research has needs beyond monetary valuation. In the future, multisubject and multimethod integrative research for understanding, modelling, evaluating, and managing the AES will be more abundant. [ABSTRACT FROM AUTHOR]

Biodiversity, including wildlife, is globally decreasing at alarming rates. This development has evoked calls for innovative conservation policies. In the present paper we explore the novel conservation performance payment approach which for wildlife–livestock conflicts, so far, has only been implemented in Sweden. The contribution of the paper is twofold. A structural framework of performance payments'' design is developed and an empirical assessment of the approach to tiger–livestock conflicts at Bandhavgarh National Park in India, an example where conservation needs compete with humans'' increasing demand for land and resources, is presented. The framework focuses on issues of scheme design such as identifying performance indicators, targeting, payment amount and timing, considerations on making payments to groups vs. individuals, scheme duration, and inadvertent side effects. The assessment of the applicability of the performance payment approach to tiger (Panthera tigris) conservation is based on a high-profile policy workshop, an interview with the park management, and 305 household-level interviews conducted in 20 villages in the buffer zone of the park.

Growing attention has been paid to gender in ecological economics, political ecology and development studies but a focus on gender in resource extraction conflicts is still rare. This article explores women-led resistance movements to commercial logging in South-eastern Cameroon, focusing on the moabi tree (Baillonella toxisperma). The latter provides oil, medicine and other non-timber products and use-values to local forest societies and particularly to women. Resistances arise because most socio-environmental costs of the international logging trade are imposed on the rural populations and especially on women of the extractive regions. The aim of this paper is to analyze the root causes of the gender structure of such mobilisations as well as the impacts on gender relations induced by such resource extraction conflicts. After proposing a typology of different environmental currents and their gender counterparts, this paper focuses on the gender construction of local Bantu societies, taking as a point of departure Paola Tabet''s thesis that masculine control over production tools is the objective factor revealing the sexual division of work. In our case study, we found that the men''s control over technology not only highlights the sexual work division but also the gendered division of access rights to natural resources. Thereby, we argue that the sexual division of access rights and work — revealed through differentiated control over technology — are two key institutions explaining the gendered structure of local mobilizations. We, then, discuss the empowerment allowed by the new forms of women''s organizations, with a particular focus on the appropriation of new production tools by women. This highlights a non-Western form of environmental feminism. [Copyright &y& Elsevier]

This paper addresses the problem of selecting reserve sites cost-effectively, taking into account the mobility and habitat area requirements of each species. Many reserve site selection problems are analyzed in mixed-integer linear programming (MILP) models due to the mathematical solvers available for this model type. Ideally, such reserve site selection models take into consideration the possibility that species use reserve sites, even small ones, as stepping stones to move from one site to another. This consideration, however, is difficult to include in MILP models. This paper demonstrates and evaluates three alternative MILP models that include species'' mobility and habitat area requirements. All models include the possible stepping stone function of reserve sites to some extent, although none does so perfectly. The models demonstrated find spatial reserve networks at lower costs than a non-spatial reserve site selection model. [Copyright &y& Elsevier]

Payments for Ecosystem Services (PES) are generating a lot of attention among conservationists because they have the potential to create new funding opportunities for biodiversity protection and other ecosystem services that contribute to human well-being. A number of recent publications have suggested ways to target and implement PES projects in order to maximize their cost-effectiveness and efficiency, and the Heredia Declaration (this issue) sets forth a list of agreed-upon principles concerning the use of PES schemes. One of those principles concerns the “bundling” of joint products of intact ecosystems in PES schemes in order to maximize the benefits to society. There have been several recent studies focusing on the degree of overlap between biodiversity and other ecosystem services and therefore the opportunities and constraints to bundling these services. Building on this idea, the bulk of this paper focuses on developing a method for selecting sites for PES where the main interest is to bundle biodiversity with other ecosystem services. We focus our analysis on Madagascar, a country with globally important biodiversity that is also beginning to explore the utility of PES as a conservation mechanism. Specifically, we assess the opportunities for bundling biodiversity conservation with carbon and water services at the national scale and identify where using PES to protect these areas of multiple benefits would be most cost-effective and efficient. This analysis identifies almost 30,000 km2 — out of 134,301 km2 — of natural habitat that could potentially meet biodiversity conservation goals and protect additional ecosystem services through a PES scheme. One of the places identified by our methodology corresponds to an ongoing conservation project that has already begun using payments from carbon emission reductions to protect standing forests and restore important biodiversity corridors — the Ankeniheny-Mantadia-Zahamena Biodiversity Conservation and Restoration Project. This project site was selected for its high biodiversity and carbon values, lending credibility to our spatial targeting methodology and providing a case study to draw insights on how multiple-benefit PES schemes can be implemented in biodiversity “hotspots”. In the discussion section of this paper we draw on experiences from this project to consider how many of the principles outlined in the Heredia Declaration affect implementation of PES schemes in Madagascar, providing lessons for similar countries experimenting with PES for biodiversity conservation.

Climate change and its consequences present one of the most important threats to biodiversity and the functions of ecosystems. The stress on biodiversity is far beyond the levels imposed by the natural global climatic changes occurring in the recent evolutionary past. It includes temperature increases, shifts of climate zones, melting of snow and ice, sea level rise, droughts, floods, and other extreme weather events. Natural systems are vulnerable to such changes due to their limited adaptive capacity. Based on an analysis using the DPSIR framework, this paper discusses some of the important socio-economic driving forces of climate change, with a focus on energy use and transportation. The paper also analyses observed and potential changes of climate and the pressures they exert on biodiversity, the changes in biodiversity, the resulting impacts on ecosystem functions, and possible policy responses. The latter can be divided into mitigation and adaptation measures. Both strategies are needed, mitigation in order to stabilise the greenhouse gas concentrations in the atmosphere, and adaptation in order to adjust to changes that have already occurred or cannot be avoided. One mitigation option, increased biofuel production, which is also a response to oil depletion, would change land use patterns and increase human appropriation of net primary production of biomass, thereby threatening biodiversity. By considering the first order and second order impacts of climate change on biodiversity when developing policy measures, it will be possible to integrate ecosystem and biodiversity protection into decision-making processes.

This paper reviews definitions and uses of the Driving Forces–Pressures–State–Impacts–Responses (DPSIR) framework and argues that it is a relevant tool for structuring communication between scientists and end-users of environmental information, while it is inappropriate as an analytical tool. An apparently deterministic ‘causal’ description of environmental issues inevitably downplays the uncertainty and multiple dimensions of causality inherent in complex environmental and socio-economic systems. Consequently, the paper complements and reframes ‘DPSIR’ using a complex system methodology based on the distinction between four ‘spheres’ of sustainability (environmental, economic, social and political) and the analysis of their functioning and relationships. The pair-wise interface aspects are characterised through investigation of the ‘demands’ and ‘supply’ of each sphere relative to the others. Within the resulting conceptual framework, each of the five D, P, S, I and R concepts are specified, for application in integrative analysis of relationships between policy, society, economy and biodiversity in one of the world's largest European integrated research projects on biodiversity (ALARM).

Abstract: This article proposes a multi-dimensional framework for understanding the development and effectiveness of Payments for Ecosystem Services (PES) schemes, framed around the notions of institutional design, performance and interplay. The framework is applied in the context of Mexico''s Programme of Payments for Carbon, Biodiversity and Agro-forestry Services (PSA-CABSA), with an emphasis on its carbon component. The analysis shows that PSA-CABSA was promoted by civil society and its rules have been subject to continuous modifications over time. In the case of the carbon component, changes have been due to an original misunderstanding of how carbon projects should be designed, implemented, and carbon traded in actual markets. From a performance point of view, the paper shows that the programme has been well received by rural communities, and carbon payments have contributed to increase household income and to enhance forest management practices and organisational skills. The paper also highlights sources of institutional interplay with local institutions and international climate policy, and it reveals the importance of capacity and scale issues in securing an effective and fair implementation of PES. The conclusion provides some policy recommendations for the future development of PES initiatives in Mexico and elsewhere. [Copyright &y& Elsevier]

In previous papers we have considered the optimal mix of biodiversity in semi-arid rangelands, focusing on the steady state. This paper addresses the question of conservation in the optimal use of rangelands, where conservation is understood to mean maintenance of the system in a ‘natural’ state. We consider a rangeland that may exist in one of two states. In the ‘natural’ state, its dynamics are regulated by fire. In the ‘managed’ state, its dynamics are regulated by grazing pressure by livestock. We show that the optimal use of rangelands may include its maintenance in both states at different points in time, depending on initial conditions and the set of relative prices.

This paper presents an approach for aiding the identification and acquisition of priority properties for biodiversity conservation. Motivation for this paper comes from the widespread acknowledgement that property acquisition choices face the challenging context of competing land uses, multiple objectives and limited funding. The approach described in this paper, based on the principles of decision analysis, links the many scientific objectives of biodiversity conservation with practical management concerns and public decision-making needs, including transparency, accountability, communication and effective use of scarce funds. After a brief introduction, a case study is presented showing how the proposed approach was used by British Columbia Parks to design and implement a property evaluation and decision support tool for acquisition of private lands as part of the provincial Protected Area Strategy. Although the case study is specific to a public protected areas strategy (PAS), the approach is applicable to other land acquisition contexts. General recommendations are discussed in light of this experience. [Copyright &y& Elsevier]

The present paper analyzes self-enforcing biodiversity agreements (or coalitions) in a multi-country general equilibrium model. Governments split up all land in unprotected and protected land, and there are internationally traded consumption goods that use either protected or unprotected land as an input in production. Global biodiversity is increasing in aggregate protected land. The willingness-to-pay for biodiversity (conservation) is larger in the ‘rich’ North than in the ‘poor’ South. There is an international market on which governments and possibly a coalition of northern countries may demand and/or offer unprotected land for conversion into protected land. If a coalition exists, it turns out to be the only demander on that market, and its demand is increasing in coalition size. We investigate the formation of self-enforcing coalitions when governments and the coalition either take prices as given or exert market power. We find that there are no such coalitions, when external biodiversity benefits are large, but there may be self-enforcing coalitions, even large ones, if these benefits are sufficiently small. Furthermore, it is possible that the South suffers a welfare loss when a self-enforcing coalition of northern countries pays for biodiversity conservation in the South. [ABSTRACT FROM AUTHOR]

Atmospheric nitrogen pollution has severe impacts on biodiversity, but approaches to value them are limited. This paper develops a spatially explicit methodology to value the benefits from improvements in biodiversity resulting from current policy initiatives to reduce nitrogen emissions. Using the UK as a case study, we quantify nitrogen impacts on plant diversity in four habitats: heathland, acid grassland, dunes and bogs, at fine spatial resolution. Focusing on non-use values for biodiversity we apply value-transfer based on household's willingness to pay to avoid changes in plant species richness, and calculate the benefit of projected emission declines of 37% for nitrogen dioxide (NO 2 ) and 6% for ammonia (NH 3 ) over the scenario period 2007–2020. The annualised benefit resulting from these pollutant declines is £32.7 m (£4.4 m to £109.7 m, 95% Confidence Interval), with the greatest benefit accruing from heathland and acid grassland due to their large area. We also calculate damage costs per unit of NO 2 and NH 3 emitted, to quantify some of the environmental impacts of air pollution for use alongside damage costs for human health in policy appraisal. The benefit is £103 (£33 to £237) per tonne of NO 2 saved, and £414 (£139 to £1022) per tonne of NH 3 saved. [ABSTRACT FROM AUTHOR]

Global efforts to protect biodiversity and slow deforestation rely heavily on the establishment of protected areas; land set aside that cannot be deforested or developed. This paper studies the macro-level relationship between rule of law and variation in avoided deforestation from protected areas. Using recent global satellite data from 2000 to 2012, I estimate the country-level avoided deforestation of protected areas established in this period via nearest-neighbor matching. I then use weighted least-squares regressions to explain country-level variation in estimated avoided deforestation as a function of a country’s governance characteristics as well as other country-level controls. Across 71 countries in this study period, protected areas were more effective in countries with higher levels of corruption control and protection of property rights, protected areas were more effective in more democratic countries, and there appears to be no relationship between political stability and avoided deforestation from protected areas.

Biological invasions entail massive biodiversity losses and tremendous economic impacts that justify significant management efforts. Because the funds available to control biological invasions are limited, there is a need to identify priority species. In this paper, we first review current invasive species prioritization methods and explicitly highlight their strengths and pitfalls. We then construct a cost–benefit optimization framework that offers the theoretical foundations of a simple method for the management of multiple invasive species under a limited budget. We provide an algorithm to operationalize this framework and render explicit the assumptions required to satisfy the management objective. [ABSTRACT FROM AUTHOR]

In this paper, we survey the literature applying viability theory to the sustainable management of renewable resources. After a refresher on the main concepts of viability theory, we provide a general map of the contributions and next discuss them by area of application, including ecosystems and population biology, climate change, forestry and others. We conclude by pointing out issues that deserve more attention and should be part of a research agenda. [ABSTRACT FROM AUTHOR]

The world is banking on a major increase in food production, if the dietary needs and food preferences of an increasing, and increasingly rich, population are to be met. This requires the further expansion of modern agriculture, but modern agriculture rests on a small number of highly productive crops and its expansion has led to a significant loss of global biodiversity. Ecologists have shown that biodiversity loss results in lower plant productivity, while agricultural economists have linked biodiversity loss on farms with increasing variability of crop yields, and sometimes lower mean yields. In this paper we consider the macro-economic consequences of the continued expansion of particular forms of intensive, modern agriculture, with a focus on how the loss of biodiversity affects food production. We employ a quantitative, structurally estimated model of the global economy, which jointly determines economic growth, population and food demand, agricultural innovations and land conversion. We show that even small effects of agricultural expansion on productivity via biodiversity loss might be sufficient to warrant a moratorium on further land conversion. [ABSTRACT FROM AUTHOR]

The EU biodiversity strategy highlights the relevance of the private sector and its prominent role as potential degrader and as protector of biodiversity. However, the topic of biodiversity seems to be downplayed and disregarded by most companies, and the potential proxies leading them to report on the matter are not yet clear. This exploratory paper aims at assessing the companies' actual engagement with the EU biodiversity strategy, and the factors influencing the relevance and quality of their disclosure indicators. To that purpose, 170 listed companies from the 5 biggest economies in the EU have been studied after their reporting indicators on biodiversity in 2018 and 2021, focusing on country, sector and impact intensity as potential drivers, as well as on the changes in reporting and indicators between those years. Our findings highlight an increased but heterogeneous engagement with biodiversity among EU listed companies, with limited relevance given by the companies to standard and quantitative performance indicators, and a strong influence on reporting of factors such as the companies' country of origin, and the companies' sector/activity. All of which suggests different approaches to biodiversity within the private sector and insufficient corporate action to meet the EU biodiversity strategy goals. • Private sector commitment with the EU Biodiversity strategy. • Trends in listed companies reporting on Biodiversity. • Determinants of biodiversity disclosure among EU listed companies. • Heterogeneity and disinterest as main factors of Biodiversity corporate reporting. • Biodiversity reporting points at insufficient corporate actions.

In spite of global actions, biodiversity is declining at an alarming rate. Despite the need for objectively comparable monetary standards to include biodiversity arguments in policymaking, research on the relationship between species diversity and its valuation from a societal perspective is still scarce. In this paper, a methodological framework for the valuation of natural predators based on their ecological role in the agroecosystem is introduced. The framework integrates a dynamic ecological model simulating interactions between species with an economic model, thereby quantifying the effect of reduced numbers of natural predators on the net farm income. The model attributes an objective monetary value to increased species diversity through the changes in the provisioning of a marketable good. Results indicate that the loss of three predators could decrease net farm income with 88.86 € ha − 1 to 2186.5 € ha − 1 . For the pear production sector in Flanders in 2011, this constitutes to an indirect use value of 0,68 million € for one predator and 16.63 million € for the presence of three predators. The aim is to provide a justification for the argument for biodiversity conservation, based on the ecological function of species, through the delivery of comparable monetary standards.

This paper addresses the representation of landscape complexity in stated preferences research. It integrates landscape ecology and landscape economics and conducts the landscape analysis in a three-dimensional space to provide ecologically meaningful quantitative landscape indicators that are used as variables for the monetary valuation of landscape in a stated preferences study. Expected heterogeneity in taste intensity across respondents is addressed with a mixed logit model in willingness to pay space. Our methodology is applied to value, in monetary terms, the landscape of the Sorrento Peninsula in Italy, an area that has faced increasing pressure from urbanisation affecting its traditional horticultural, herbaceous, and arboreal structure, with loss of biodiversity, and an increasing risk of landslides. We find that residents of the Sorrento Peninsula would prefer landscapes characterised by large open views and natural features. Residents also appear to dislike increasing level of landscape heterogeneity and the presence of lemon orchards and farmers' stewardship, which are associated with the current failure of protecting the traditional landscape. The outcomes suggest that the use of landscape ecology metrics in a stated preferences model may be an effective way to move forward integrated methodologies to better understand and represent landscape and its complexity.

Specialization in agricultural systems can lead to trade-offs between economic gains and ecosystem functions. We suggest and explore a conceptual framework in which economic gains can be maximized when production activities are specialized at increasingly broader scales (from the household to the village, region or above), particularly when markets for outputs and inputs function well. Conversely, more specialization likely reduces biodiversity and significantly limits ecosystem functions. When agricultural specialization increases and moves to broader scales as a result of improved infrastructure and markets or other drivers, ecosystem functions can also be endangered at broader spatial scales. Policies to improve agricultural incomes may influence the level of specialization at different scales and thus affect the severity of the trade-offs. This paper takes Jambi province in Indonesia, a current hotspot of rubber and oil palm monoculture, as a case study to illustrate these issues. We empirically show that the level of specialization differs across scales with higher specialization at household and village levels and higher diversification towards the province level. We discuss ways to resolve trade-offs between economic gains and ecological costs, including landscape design, targeted policies, and adoption of long-term perspectives. [ABSTRACT FROM AUTHOR]

There is growing concern that the way that soils are used often results in their degradation, giving rise to significant costs, both to direct users of soils and to society as a whole. This paper develops and uses an approach to derive the total economic cost of soil degradation in England and Wales. An estimate was made of degradation costs at the national scale for dominant combinations of land cover and soils, defined as ‘soilscapes’. An ecosystem services framework was used to assess how degradation affects the capacity of soils to support a range of ‘final goods’, distinguishing between on-site and off-site costs, and market and non-market effects. Quantifiable soil degradation costs ranged between £0.9 bn and £1.4 bn per year, with a central estimate of £1.2 bn, mainly linked to loss of organic content of soils (47% of total cost), compaction (39%) and erosion (12%). Eighty percent of costs occur off-site and, as such, are often of limited concern to those whose actions may be causing soil degradation. The findings confirm that control of soil degradation has implications for a number of key policy areas such as flood risk management and climate change mitigation. [ABSTRACT FROM AUTHOR]

This paper applies a stochastic viability approach to a tropical small-scale fishery, offering a theoretical and empirical example of ecosystem-based fishery management approach that accounts for food security. The model integrates multi-species, multi-fleet and uncertainty as well as profitability, food production, and demographic growth. It is calibrated over the period 2006–2010 using monthly catch and effort data from the French Guiana's coastal fishery, involving thirteen species and four fleets. Using projections at the horizon 2040, different management strategies and scenarios are compared from a viability viewpoint, thus accounting for biodiversity preservation, fleet profitability and food security. The analysis shows that under certain conditions, viable options can be identified which allow fishing intensity and production to be increased to respond to food security requirements but with minimum impacts on the marine resources.

In this paper, we examine the extent, range, and diversity of noncommercial wild ocean seafood subsistence harvests among commercial operators in Washington and California, USA and test the relationship between subsistence drivers and market behavior. Analyzing data from Pacific Fisheries Information Network between 1990 and 2010, we show that over 17 million kg of fish and shellfish were kept for personal use. We used general additive models to examine patterns in proportion of personal use versus price for the top 10 species retained over the 20-year period for each of the three population groups: Washington commercial tribal (indigenous) fishing operators, Washington commercial nontribal operators, and California commercial fishing operators. Out of the 26 species-price relationships tested, only one fits the market relationship with statistical significance and the model failed to predict personal use patterns for any of the other species. We conclude that market sensitivity is not a reliable predictor for subsistence behavior. Although a nominal figure in the overall seafood catch, the presence of subsistence practices among 21st century market-based commercial fishing operators reveals a more diverse array of economic systems than previously imagined. We suggest that alternative economies, including subsistence and associated community share systems, function to improve human wellbeing and strengthen community resilience by increasing food security and community food systems, engaging in a quality of life practice, and supporting social networks through seafood gifting and sharing.

Biodiversity is a highly complex and abstract ecological concept. Even though it is not one physical entity, it influences human well-being in multiple ways, mostly indirectly. While considerable research effort has been spent on the economic valuation of biodiversity, it remains to be a particularly challenging ‘valuation object’. Valuation practitioners therefore have to use proxies for biodiversity, many of which are very simple (single species, habitats). This paper presents a comprehensive and critical review of biodiversity valuation studies with special emphasis on bio diversity valuation in order to depict the state-of-the-art in this research field. It develops evaluation criteria so as to identify best-practice applications and shows that the field of biodiversity valuation studies is rather heterogeneous regarding both valuation objects and valuation methods. On the basis of our evaluation criteria and best-practice studies we suggest that to account for the complexity and abstractness of biodiversity, multi-attribute approaches with encompassing information provision should be used that emphasise the roles biodiversity plays for human well-being.

Abstract: This paper constitutes a first attempt to model the relationship between climate change, biodiversity, and ecosystem services, with a specific emphasis on European forests. Firstly, we construct a composite biodiversity indicator that integrates quantitative and qualitative changes of biodiversity projected to 2050 for the EU-17 under future IPCC scenarios. Secondly, this indicator is integrated into two simultaneous equation models to capture the marginal impacts of changes in biodiversity on the value of ecosystem goods and services (EGS) due to climate change. Our estimation results confirm the role of biodiversity as a nature-based policy solution for climate change mitigation, shedding light on the policy actions that generate co-benefits by enhancing ecosystems' capacity to mitigate climate change impacts, while conserving biodiversity and sustaining the flows of EGS for human livelihoods. Especially, nature-based mitigation policies are more cost-effective and better at coping with the ethic and inequality issues associated with distributional impacts of the policy actions, compared to the pure technical solutions to improving energy efficiency and reducing emissions. However, the strength of biodiversity as a nature-based policy option for climate change mitigation depends on both the nature of the EGS and the geographical area under consideration.

Is there a trade-off between spending on the green economy and an economy's strength? This paper addresses this question by estimating output multipliers for spending in clean energy and biodiversity conservation, and by comparing these to multipliers of spending on non-ecofriendly energy and land use activities. Using a new international dataset, we arrive at two key results. First, we find that every dollar spent on key carbon-neutral or carbon-sink activities can generate more than a dollar's worth of economic activity, whereas non-green spending returns less than a dollar. Second, for categories of spending where formal comparisons are possible, like renewable versus fossil fuel energy, we find that multipliers on green spending are about twice as large as their non-green counterparts. The point estimates of the multipliers are 1.1–1.7 for renewable energy investment and 0.4–0.7 for fossil fuel energy investment, depending on horizon and specification. These findings survive several robustness checks and lend support to bottom-up analyses that find that stabilizing climate and reversing biodiversity loss go hand in hand with economic prosperity.

Abstract: This paper analyses the development and emergence of market based instruments for biodiversity conservation in Central and Eastern European (CEE) countries. The development of market-based instruments for biodiversity conservation has been receiving increased attention as a possible cheaper and more effective alternative to the global regulatory approach. The implementation of such instruments is particularly challenging in post-socialist countries, where the former state command-and-control economy disturbed the normal functioning of markets. Our analysis indicates that market-based instruments can increase the effectiveness of biodiversity conservation, but are not always suitable and appropriate. The following preconditions for the effective design of market-based instruments in CEE countries have been identified: clear property rights and decision making structure, transparent rules for information dissemination, and monitoring responsibilities. Our results show that the successful implementation of market-based instruments for biodiversity conservation in CEE countries is furthermore influenced by pre-existing formal and informal institutions, in which reputation and trust may play a role. However, market-based instruments should complement rather than substitute regulatory approaches, and in combination with traditional regulation, such can become critical in achieving the objectives of biodiversity conservation.

Abstract: To decide on the policy measures to be implemented, policymakers need comprehensive information on the costs and benefits of land conversion for society. Accordingly, the EU Biodiversity Strategy requires the member countries to assess their ecosystems and the economic value of their ecosystem services by 2020. This paper takes up and extends the subjective well-being approach to valuing changes in natural land cover, which provides information on willingness-to-pay for landscape amenities such as scenic views or recreational opportunities. Results at the NUTS 2 level for European countries indicate (a) that marginal willingness-to-pay estimates tend to be higher for natural areas that are scarcer, and (b) that a nonlinear relationship between land cover and well-being is preferred to a linear relationship indicating decreasing benefits from individual landscape amenities.

Abstract: Predictions of future land use areas are an important issue as land use patterns significantly impact environmental conditions (biodiversity, water pollution, soil erosion, and climate change) as well as economic and social welfare. In order to improve the prediction accuracy of aggregated land use share models, we propose in this paper a methodological contribution by controlling for both unobserved individual heterogeneity and spatial autocorrelation. Our model is a land use shares model applied to aggregated data in France. Our dataset is a panel which covers both time series observations from 1992 to 2003 and cross-sectional observations by Département (equivalent to NUTS3 regions). We consider four land use classes: (1) agriculture, (2) forest, (3) urban and (4) other use. We investigate the relation between the areas in land in different alternative uses and economic and demographic factors influencing land use decisions. Based on the comparison of prediction accuracy of different model specifications, our findings are threefold: First, controlling for both unobserved individual heterogeneity and spatial autocorrelation outperforms any other specification in which spatial autocorrelation and/or individual heterogeneity are ignored. Second, accounting for cross-equation correlations does not seem to improve the prediction performances and finally, ignoring individual heterogeneity introduces substantial loss in prediction accuracy.

Abstract: The consumption of meat from wild animals (or bushmeat) occurs throughout Africa and highlights the conflict between two distinct development goals: food security and biodiversity conservation. Growing human populations throughout the greater Serengeti ecosystem rely heavily on bushmeat as a source of protein, which places pressure on migratory wildlife populations. This paper uses unique data from protein consumption surveys from 131 households over 34months in a generalizable empirical framework to estimate price, cross-price, and expenditure elasticities of protein sources, and analyze the potential economic effects of policies to mitigate bushmeat hunting and consumption. Results suggest that: (1) directly increasing the price of bushmeat through enforcement or other policies to reduce supply will have the most direct and largest effect of bushmeat consumption; (2) increasing income increases bushmeat consumption as well as consumption of other meat sources; (3) if surrounding fisheries experience a negative shock, or collapse, this will lead to a dramatic increase in bushmeat consumption. Overall, these results strongly indicate that policies to reduce bushmeat hunting while maintaining food security must be considered in a broad and comprehensive framework. [Copyright &y& Elsevier]

Abstract: Biodiversity is an essential resource, which we classify as conditionally-renewable. In order to achieve conservation and sustainable use of biodiversity virtually all nation states signed the United Nations Convention on Biological Diversity. In this paper we investigate how the heterogeneity of countries in regard to ecosystems and wealth influences the stability of international biodiversity conservation agreements both without and with transfers. We further examine the effect of different degrees of ecosystem substitutability. We model a coalition formation game with players that have a continuous conservation choice. The conservation benefit is dependent on wealth and ecosystem quality. Aggregation of global benefits respects differences in ecosystem substitutability. In case of transfers, a fund redistributes coalition benefits according to a sharing rule. The main finding is that in the absence of transfers, compared to the homogeneous situation, heterogeneity in ecosystems and wealth reduces the size of a stable coalition. The destabilising effect is stronger the higher the ecosystem substitutability. Optimal transfers facilitate a large stable coalition. [Copyright &y& Elsevier]

This paper examines worldwide tourist coastal destination choice using a comprehensive global dataset at the country level, for both domestic and international tourists. This data includes a systematic profile of the countries'' coastline with respect to economic and natural environments, such as marine biodiversity related indicators. Tourist demand is modelled using a system of simultaneous structural equations estimated by a 3SLS routine. We identify two tourist demand segments, denoting different preferences for the worldwide coastal destinations. International tourists choose their coastal destination because they have a strong preference for the cultural and natural environments. This, in turn, depends on the destination of country's coastal habitat abundance and marine biodiversity. We label this segment of coastal tourism, as “greens”. Alternatively, domestic tourists have a preference for beach characteristics, in particular beach length. This in turn depends on anthropogenic pressure, the built environment and climatic variables. For this reason we interpret this tourism segment as “beach lovers”. This information is, in turn, of high significance for stimulating coastal tourism demand as well as for identifying market based policy instruments with the objective to finance the conservation of environmental and cultural capital hosted at the coastal communities.

Abstract: The aim of this paper is to compare different environmental policies for cost-effective habitat conservation on agricultural lands, when the desired spatial pattern of reserves is a random mosaic. We use a spatially explicit mathematical programming model which studies the farmers'' behavior as profit maximizers under technical and administrative constraints. Facing different policy measures, each farmer chooses the land-use on each field, which determines the landscape at the regional level. A spatial pattern index (Ripley L function) is then associated to the obtained landscape, indicating on the degree of dispersion of the reserve. We compare a subsidy per hectare of reserve with an auction scheme and an agglomeration malus. We find that the auction is superior to the uniform subsidy for cost-efficiency. The agglomeration malus does better than the auction for the spatial pattern but is more costly. [Copyright &y& Elsevier]

Abstract: Biodiversity supports a range of ecosystems services that are of fundamental importance to people in poor countries. Economic valuation of biodiversity is important for the development of policies that protect biodiversity and alleviate poverty. This paper provides an evaluation of monetary and non-monetary techniques for assessing the value of biodiversity to people in least developed countries (LDCs). Specifically, research questions include: [1)] To what extent have monetary and non-monetary techniques been used to assess the value of biodiversity and ecosystem services in LDCs? [2)] What are the key methodological, practical, epistemological and policy challenges to assessing the value of biodiversity and ecosystem services in LDCs? [3)] How can valuation methods be improved to allow more accurate valuation in LDCs? [Copyright &y& Elsevier]

This paper presents a cost-benefit analysis of three different use systems for the remaining cloud forests in Ethiopia, which at present are being depleted at the rate of 8% per year. These use systems are a) traditional conversion to crop land, b) sustainable management of the forest (e.g. by growing high-quality, semi-forest coffee), and c) strict conservation. We find that under business as usual conversion to cropland yields the highest net present income value for the local population. Taking into account watershed services, sustainable forest use is in the best interests of the country for discount rates of 10% or lower. Taking into account the global benefits of biodiversity conservation and carbon storage, sustainable forest management also yields the highest total economic value while strict conservation does not pass a cost-benefit test even at a discount rate of 3%.

Business activities play a major role in biodiversity loss so that firms are under increasing pressures from stakeholders to mitigate their negative impacts on ecosystems. As business attitudes, policies and behaviors regarding biodiversity and ecosystem services (BES) progressively change, a better understanding of how business strategies may be framed and implemented is required. In the first part of this paper, we discuss how biodiversity is usually understood as an external environmental constraint on business activities, and how this perception influences arbitrages. We then discuss how assessing BES interdependencies (impacts and dependencies) may bring about new business strategies and needs: we explore the opportunities and challenges of emerging mechanisms of payments for ecosystem services and expose the need for standardized sets of indicators at different scales for the effective management of their BES dependencies and impacts.

This paper focuses on examining the validity of biodiversity valuation methodologies. The results of a group deliberation technique (deliberative monetary valuation) are compared to those derived from a contingent valuation (CV) survey using the same environmental topic. Evidence is here presented that DMV can address some of the limitations of CV; namely a prevalence for lexicographic preference ordering due to psychological reasons and the lack of a priori or well-formed preferences. Both of these methodological shortcomings can result in protest responses which decrease the external validity of results. It is common environmental valuation methodology practice to exclude protest responses from the analysis on the grounds that they are illegitimate choices, thus the sample and consequently the environmental valuation analysis may become less representative of the population. An advantage of the DMV methodology is that it was found to significantly reduce the rate of protest responses to less than half (from 29% to 13%). Furthermore, DMV significantly increased the proportion of positive bids but not the amounts contributed. In relation to preference formation issues, we suggest rethinking the current practice of the DMV method, and propose dedicating the entire initial discussion session to introducing the good outside of a valuation context.
