Political markets? Politics and economics in the emergence of markets for biodiversity offsets

This paper analyses the relationship between politics and performativity of economics in the emergence of markets for biodiversity offsets. While the role of economics in constructing markets has been demonstrated by sociology and social studies of science, it has also become apparent that politics plays an important role in the material outcome of economic experiments. Two case studies of the creation of markets for biodiversity offsets are analysed, in the United States and England. The findings suggest that the creation of both markets is rooted in the language, concepts and models of economics. Politics, on the other hand, functions as a mediator of the material expression of those models. Through this mediation effect, similar economic models are performed differently, resulting in a variety of markets. This suggests that the material outcomes of processes of market creation are not defined at the outset, but can be influenced by political processes.     

European firms’ corporate biodiversity disclosures and board gender diversity from 2002 to 2016

We examine how board gender diversity is associated with biodiversity disclosures of a firm, and whether the Global Reporting Initiative (GRI) and the EU biodiversity strategy reinforce this relationship. Using institutional theory and resource dependency theory, our sample comprises 4013 firm-year observations from European corporations covering data from 2002 to 2016. We use panel regressions with country, time and industry dummy variables to analyse the disclosure of biodiversity initiatives (DBI) and logit regressions to explain biodiversity impact assessment (BIA). We find that board gender diversity is positively associated with the DBI and BIA of a firm, and that the GRI framework and the EU biodiversity strategy positively moderate this relationship. Moreover, the GRI framework and the EU strategic plan show positive relationship with the DBI, rather than BIA. Altogether, our evidence suggests that corporate boards with a higher proportion of female directors are more sensitive to the concerns of institutional pressures and respond to those concerns by increasing corporate biodiversity disclosures. Overall, we find that firms tend to comply with the GRI framework and the EU 2020 strategy by undertaking symbolic biodiversity disclosures, rather than providing a comprehensive disclosure of their impacts on biodiversity.     

Payments for ecosystem services and corporate social responsibility: Perspectives on sustainable production,stakeholder relations,and philanthropy in Thailand

Payments for ecosystem services (PES) are environmental management tools that enable corporations to simultaneously enhance their environmental performance and fund sustainable development in rural areas. PES is primarily promoted as part of a sustainable production strategy for conserving natural resources, offsetting carbon emissions, and green supply chain management. Nevertheless, PES uptake by the private sector remains low, and few studies have analysed whether corporate‐financed PES schemes conform to this rationale. This study evaluates three of the first PES schemes in Thailand, financed by large corporations in the water utilities, aquaculture, and beverage sectors. Interviews with 39 business managers and project stakeholders suggest that PES may be viewed as a tool for philanthropy, public relations, and gaining license to operate—akin to many corporate social responsibility initiatives. Explanations and ramifications are discussed in the context of ecological uncertainty, risk management, financial performance, organisational learning, and the corporate‐engagement strategies of non‐governmental organisations.

On the Opportunity Cost of Crop Diversification

Distance functions are increasingly being augmented, with environmental goods treated as conventional outputs. A common approach to evaluate the opportunity cost of providing an environmental good is the exploitation of the distance function's dual relationship to the value function. This implies that the opportunity cost is assumed to be non‐negative. This approach also requires a convex technology set. Focusing on crop diversification for a balanced sample of 44 cereal farms in the East of England for the years 2007–2013, this paper develops a novel opportunity cost measure that does not depend on these strong assumptions. We find that the opportunity cost of crop diversification is negative for most farms.     

Conservation finance and sustainable tourism: the acceptability of conservation fees to support the Tambopata National Reserve,Peru

Protected areas are key to the conservation of global biodiversity and ecosystem services; however, their success is contingent upon adequate funding. One possibility to increase funding for park management is to “sell” a wider suite of ecosystem services “produced” by protected areas, such as carbon sequestration. We conducted 420 tourist surveys to analyze willingness to pay (WTP) for ecosystem service benefits via a conservation fee in the Tambopata National Reserve in Peru. We also interviewed eight tour operators about their perceptions of the proposed fee. The average stated WTP was 15 USD. Sixty-six percent of tourists stated they would pay 10 USD or more, which, if actually paid, would have resulted in 318,000 USD for park management in 2015. Most respondents stated they would pay an additional fee if it supported biodiversity conservation or local ecosystem services, such as water, but less than 10% of tourists were motivated by carbon sequestration as a reason to pay the fee. Most tour operators supported the additional fee. Our findings suggest that tourists are willing to pay higher fees to support conservation but that interest in paying for additional ecosystem services from parks may not extend to global and intangible benefits such as carbon sequestration.     

Reducing tourism's threats to biodiversity: effects of a voluntary sustainability standard and training program on 106 Latin American hotels,lodges and guesthouses

The tourism industry can negatively affect wildlife, plants and natural ecosystems through habitat destruction, pollution, over-exploitation of natural resources and visitor impacts to sensitive ecosystems. One approach to mitigate such threats is the application of voluntary sustainability standards, supported by training of tourism enterprises and verified by external audits. The Rainforest Alliance standard defines 78 criteria (requirements) for sustainable environmental, social and business practices, and has been adopted by over 600 tourism enterprises – including hotels, lodges and tour boats – in 12 countries. We examined the performance of 106 hotels in six Latin American countries against 29 of the sustainable tourism criteria most directly related to biodiversity conservation. Independent audits were used to assess hotel performance at baseline followed by a repeat assessment after training, about two years later. Mean conformance with the 29 biodiversity criteria increased significantly during this interval, from 44% to 58%. Improvements were greatest for businesses in the lowest third of performance at baseline (laggards) and smallest for hotels in the highest third (leaders). The results indicate that a voluntary sustainability standard and training program can serve both to recognize existing good actors and to drive incremental improvement in enterprises that were previously less sustainable.

Farmers,Biodiversity and Plant Protection: Developing a Learning Environment for Sustainable Tree Cropping Systems

More diverse, perennial cropping systems often have better natural mechanisms for keeping pests at bay. But while scientists emphasise the broad benefits of conservation in terms of effective ecosystem functioning, farmers are more interested in biodiversity for the provision of food or of services such as shade or windbreaks. Because of their limited knowledge of the role of biodiversity in plant protection, farmers sometimes unconsciously disturb natural regulatory mechanisms. Some citrus farmers in Vietnam introduced sapodilla as an intercrop to diversify their source of income, and because this fruit tree requires little care. However, this apparently worthwhile attempt to combine two valuable crops has misfired. The ecological conditions that traditionally sustained natural pest control in citrus have been disturbed, thus trapping farmers in the pesticide treadmill. The weaver ant Oecophylla smaragdina stopped protecting citrus from stinkbugs and leaf-feeding caterpillars after facing competition from the black ant Dolichoderus thoracicus, which favours sapodilla trees as a nesting habitat. To avoid similar scenarios in the future, methods for linking scientific research on ecosystem functions with farmers' own knowledge, experience and priorities are presented. Examples are given of ways in which farmers in perennial cropping systems learn, and how scientists can facilitate this learning process.     

Seeing the forest for the trees: tourism and the International Year of Forests

The year 2011 is the United Nations International Year of Forests. In addition to performing extremely significant environmental, economic, and social services, forests are also important tourism attractions in their own right and locations for recreation and tourism activities. The limited statistical data available suggest that there are billions of tourism and recreational visits to forests each year. This paper provides a global overview of biodiversity conservation, protected areas, recreational access, and management objectives in forests before outlining some of the main themes in the relationship between tourism and forests. It concludes that there is a need for a research effort on tourism and forests in order to provide greater recognition for the economic and environmental contributions of tourism in forest areas as well as the overall value of forests for health and wellbeing.
