RESUMEN

Stated preference valuation of ecosystem services involves participants answering hypothetical questions to express preferences. Participants tend to respond to the hypothetical questions separately, without any deliberation (the process of considering and discussing within a group). However, a relatively recent development in deliberation research involves asking participants to state preferences via deliberation. Deliberation is historically conducted in-person but can now also be done online. This paper covers the strengths and limitations of integrating online deliberation into stated preference valuation, including: (1) comparison between stated preference valuation with and without deliberation, (2) comparison between in-person and online deliberation, and (3) comparison between online deliberation media, such as typing, video meetings, and voice calls. Conducting deliberation can broaden participants' understanding of the target ecosystem services and others' preferences. However, this requires participants' willingness to deliberate and increases time investment. Online deliberation has lower costs and travel restrictions and higher time efficiency and confidentiality of personal information than in-person deliberation. However, people with low abilities or willingness to use online media are disadvantaged. Differences in the online deliberation media may reduce or improve the inclusiveness, engagement, and openness of deliberations in ways that affect valuation results. We also provide suggestions for selecting deliberation media and mitigating deliberation bias derived from the choice of deliberation media. Further research should explore how to improve time efficiency and affordability of online deliberation, how to promote inclusiveness, engagement, and openness of online deliberation, and how different deliberation media affect deliberation quality and valuation results.

RESUMEN

An ecosystem is healthy if it is active, maintains its organization and autonomy over time, and is resilient to stress. Healthy ecosystems provide human well-being via ecosystem services, which are produced in interaction with human, social, and built capital. These services are affected by different ecosystem stewardship schemes. Therefore, society should be aiming for ecosystem health stewardship at all levels to maintain and improve ecosystem services. We review the relationship between ecosystem health and ecosystem services, based on a logic chain framework starting with (1) a development or conservation policy, (2) a management decision or origin of the driver of change, (3) the driver of change itself, (4) the change in ecosystem health, (5) the change in the provision of ecosystem services, and (6) the change in their value to humans. We review two case studies to demonstrate the application of this framework. We analyzed 6,131 records from the Ecosystem Services Valuation Database (ESVD) and found that in approximately 58% of the records data on ecosystem health were lacking. Finally, we describe how the United Nations' System of Environmental-Economic Accounting (SEEA) incorporates ecosystem health as part of efforts to account for natural capital appreciation or depreciation at the national level. We also provide recommendations for improving this system.

RESUMEN

"Accounting values" (quantity * unit value), assessed with an assumption of a constant unit value, are often used in creating macroeconomic aggregates like Gross Domestic Product (GDP). This approach has also been used to estimate the total value of ecosystem services (ES) - the benefits humans receive from functioning ecosystems. In China, this has been referred to as Gross Ecosystem Product (GEP). While the concepts of value and ES may be understood from multiple perspectives, ESs' accounting values contribute important information to the discussion of land use trade-offs in China's protected areas (PAs). These trade-offs include (1) whether additional conserved lands should be opened to tourism development, since tourism brings both positive and negative impacts; (2) whether PAs should be reduced, maintained, or expanded, since PAs safeguard sustainable wellbeing but also require maintenance; and (3) how to undertake conservation on lands traditionally used for human livelihood development, since conservation and livelihood may conflict. Previous studies have suggested (1) joint evaluation based on both GDP and ESs' values may lead to more sustainable decision-making than solely GDP-oriented evaluation; (2) the benefits of maintaining terrestrial PAs in China is $2.64 trillion/yr, over 14 times greater than the costs; (3) integrating ES valuation into environmental impact assessment helps link environmental impacts with human wellbeing and financial costs (e.g., land encroachment of a tourism highway in the Wulingyaun Scenic Area was estimated to cause permanent loss of ES values at $0.5 million/yr); and (4) integrating non-marketable cultural ESs into payment for ESs schemes can further balance conservation with livelihood development. Future research should consider (1) option and non-use values to present a more comprehensive picture of PAs' contributions to sustainable wellbeing and human interdependence with the rest of nature (2) both PAs' quantity (e.g., optimal coverage of PAs); and quality (e.g., management effectiveness, connectivity); (3) more sophisticated and feasible valuation methods (e.g., more cost-effective and engaged deliberation) to improve the credibility of aggregate values over large spatial scales; and (4) interaction between environmental components and ESs.

RESUMEN

Ecosystems (natural capital) produce a range of benefits to humans. Natural capital is best thought of as common property since many of the ecosystem services it helps produce are non-rival and/or non-excludable. Private property regimes and markets alone are ineffective and inappropriate institutions to manage them sustainably. These systems can be better managed as commons, using more nuanced private and community property rights and Common Asset Trusts (CATs), with legal precedent in the Public Trust Doctrine. Effective CATs embody a generalized version of Elinore Ostrom's eight core design principles for sustainable commons management: (1) shared identity and purpose; (2) equitable distribution of contributions and benefits; (3) fair and inclusive decision-making; (4) monitoring agreed behaviours; (5) graduated responses; (6) fast and fair conflict resolution; (7) authority to self-govern; and (8) collaborative relations with other groups and spatial scales. Here, we describe a few existing and proposed systems that approximate effective CATs. We also suggest how Costa Rica can transform its existing payment for ecosystem services (PES) scheme into a national CAT. Finally, we describe how CATs can facilitate more fair and effective public/private partnerships (PPPs) to invest in natural capital and ecosystem services.

RESUMEN

A high and sustainable quality of life is a central goal for humanity. Our current socio-ecological regime and its set of interconnected worldviews, institutions, and technologies all support the goal of unlimited growth of material production and consumption as a proxy for quality of life. However, abundant evidence shows that, beyond a certain threshold, further material growth no longer significantly contributes to improvement in quality of life. Not only does further material growth not meet humanity's central goal, there is mounting evidence that it creates significant roadblocks to sustainability through increasing resource constraints (i.e., peak oil, water limitations) and sink constraints (i.e., climate disruption). Overcoming these roadblocks and creating a sustainable and desirable future will require an integrated, systems level redesign of our socio-ecological regime focused explicitly and directly on the goal of sustainable quality of life rather than the proxy of unlimited material growth. This transition, like all cultural transitions, will occur through an evolutionary process, but one that we, to a certain extent, can control and direct. We suggest an integrated set of worldviews, institutions, and technologies to stimulate and seed this evolutionary redesign of the current socio-ecological regime to achieve global sustainability.

RESUMEN

While self-reported life satisfaction (LS) has become an important research and policy tool, much debate still surrounds the question of what causes LS to change in certain individuals, while not in others. Set-point theory argues that individuals have a relatively resilient LS or "set point" (i.e. there is a certain LS level that individuals return to even after major life events). Here, we describe the extent to which LS varies over time for 12,643 individuals living in Australia who participated in at least eight annual waves of the Household Income and Labour Dynamics in Australia (HILDA) Survey. We use the standard deviation (SD) of year-on-year LS by individuals (SD of LS) as a measure of instability and an inverse proxy for resilience. We then model SD of LS as the dependent variable against average LS scores over time by individual, Big Five personality scores by individual, the number of waves the individual participated in, and other control variables. We found that SD of LS was higher (lower resilience) in participants with a lower average LS and greater degrees of extraversion and agreeableness. Set-point theory thus applies more to individuals whose average LS is already high and whose personality traits facilitate higher resilience. We were able to explain about 35% of the stability in LS. These results are critical in designing policies aimed at improving people's lives.

RESUMEN

Indicators that attempt to gauge wellbeing have been created and used at multiple spatial scales around the world. The most commonly used indicators are at the national level to enable international comparisons. When analyzing subjective life satisfaction (LS), an aspect of wellbeing, at multiple spatial scales in Australia, variables (drawn from environmental, social, and economic domains) that are significantly correlated to LS at smaller scales become less significant at larger sub-national scales. The reverse is seen for other variables, which become more significant at larger scales. Regression analysis over multiple scales on three groups (1) all individuals within the sample, (2) individuals with self-reported LS as dissatisfied (LS ≤ 5), and (3) individuals self-reporting LS as satisfied (LS > 5), show that variables critical for LS differ between subgroups of the sample as well as by spatial scale. Wellbeing measures need to be created at multiple scales appropriate to the purpose of the indicator. Concurrently, policies need to address the factors that are important to wellbeing at those respective scales, segments, and values of the population.

RESUMEN

China has a long history of building hard engineered coastal defences for storm protection, which enables us to examine the economic effects of the hard engineering to mitigate storm damage. Examining historical storm impacts between 1989 and 2016, a significant negative relationship exists between the relative economic damages (i.e., TD/GDP) by storm and the length of existing hard engineering within the storm swath. This indicates that hard engineered defences play a critical role in storm mitigation. We estimated that the storm protection value provided by hard engineered defences in China is CNY 3.18 million/km [US$0.50 million/km] on average, with a median of CNY 1.69 million/km [US $0.27 million]. They provide an annual economic value of CNY 6.04 billion on average. Despite their great contribution to reduce total economic damages from storms, hard engineered defences are not as efficient as coastal wetlands. Coastal wetlands are more cost effective based on comparison from China and USA. This study highlights the need for the Chinese government to transfer focus from prevailing hard engineered defences to ecosystem-based measure or the combination of both measures to prevent storm damage in the future.

RESUMEN

Ecosystem services (the benefits to humans from ecosystems) are estimated globally at $125 trillion/year [1, 2]. Similar assessments at national and regional scales show how these services support our lives [3]. All valuations recognize the role of biodiversity, which continues to decrease around the world in maintaining these services [4, 5]. The giant panda epitomizes the flagship species [6]. Its unrivalled public appeal translates into support for conservation funding and policy, including a tax on foreign visitors to support its conservation [7]. The Chinese government has established a panda reserve system, which today numbers 67 reserves [8, 9]. The biodiversity of these reserves is among the highest in the temperate world [10], covering many of China's endemic species [11]. The panda is thus also an umbrella species [12]-protecting panda habitat also protects other species. Despite the benefits derived from pandas, some journalists have suggested that it would be best to let the panda go extinct. With the recent downlisting of the panda from Endangered to Vulnerable, it is clear that society's investment has started to pay off in terms of panda population recovery [13, 14]. Here, we estimate the value of ecosystem services of the panda and its reserves at between US$2.6 and US$6.9 billion/year in 2010. Protecting the panda as an umbrella species and the habitat that supports it yields roughly 10-27 times the cost of maintaining the current reserves, potentially further motivating expansion of the reserves and other investments in natural capital in China.

RESUMEN

Making trade-offs between ecological services and other contributors to human well-being is a difficult but critical process that requires valuation. This allows both better recognition of the ecological, social, and economic trade-offs and also allows us to bill those who use up or destroy ecological services and reward those that produce or enhance them. It also aids improved ecosystems policy. In this paper we clarify some of the controversies in defining the contributions to human well-being from functioning ecosystems, many of which people are not even aware of. We go on to describe the applicability of the various valuation methods that can be used in estimating the benefits of ecosystem services. Finally, we describe some recent case studies and lay out the research agenda for ecosystem services analysis, modeling, and valuation going forward.
