Why nature matters: A systematic review of intrinsic, instrumental, and relational values.

In this article, we present results from a literature review of intrinsic, instrumental, and relational values of nature conducted for the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services, as part of the Methodological Assessment of the Diverse Values and Valuations of Nature. We identify the most frequently recurring meanings in the heterogeneous use of different value types and their association with worldviews and other key concepts. From frequent uses, we determine a core meaning for each value type, which is sufficiently inclusive to serve as an umbrella over different understandings in the literature and specific enough to help highlight its difference from the other types of values. Finally, we discuss convergences, overlapping areas, and fuzzy boundaries between different value types to facilitate dialogue, reduce misunderstandings, and improve the methods for valuation of nature's contributions to people, including ecosystem services, to inform policy and direct future research.

Diverse values of nature for sustainability.

Twenty-five years since foundational publications on valuing ecosystem services for human well-being1,2, addressing the global biodiversity crisis3 still implies confronting barriers to incorporating nature's diverse values into decision-making. These barriers include powerful interests supported by current norms and legal rules such as property rights, which determine whose values and which values of nature are acted on. A better understanding of how and why nature is (under)valued is more urgent than ever4. Notwithstanding agreements to incorporate nature's values into actions, including the Kunming-Montreal Global Biodiversity Framework (GBF)5 and the UN Sustainable Development Goals6, predominant environmental and development policies still prioritize a subset of values, particularly those linked to markets, and ignore other ways people relate to and benefit from nature7. Arguably, a 'values crisis' underpins the intertwined crises of biodiversity loss and climate change8, pandemic emergence9 and socio-environmental injustices10. On the basis of more than 50,000 scientific publications, policy documents and Indigenous and local knowledge sources, the Intergovernmental Platform on Biodiversity and Ecosystem Services (IPBES) assessed knowledge on nature's diverse values and valuation methods to gain insights into their role in policymaking and fuller integration into decisions7,11. Applying this evidence, combinations of values-centred approaches are proposed to improve valuation and address barriers to uptake, ultimately leveraging transformative changes towards more just (that is, fair treatment of people and nature, including inter- and intragenerational equity) and sustainable futures.

"My place in the grand scheme of things": perspective from nature and sustainability science.

A burgeoning and diverse field of study investigates the many aspects of human-nature relationships-what they mean for ecosystems, for human well-being, and for transformations toward sustainability. We explore an emerging concept in human-nature relationship research: perspective from nature, defined as the idea that nature helps people gain perspective on where they fit in the world and what is important (what some people call a "reality check"); in most cases, this involves a shift of attention beyond themselves and their particulars. We analyze responses to open-ended questions in a survey (n = 3204) focused on how residents of Vermont, USA, experienced nature during the early months of the COVID-19 pandemic. We identify 481 instances and six aspects of perspective from nature; ouranalysis deepens existing understandings of the concept. We connect perspective from nature to five emerging areas of study in global change research: the multiple values of nature, nature's mental health benefits, mindfulness, humility, and empathy. Perspective, this work suggests, is a construct that crosses multiple fields of study within human-nature relationships and offers potentially important insight into the role experience with nature may play in transitions toward sustainability.

Lessons from an experiment with values-based messaging to support watershed conservation.

Conservation professionals use language related to instrumental, intrinsic, and relational values when communicating about the importance of conservation, frequently in connection with ecosystem services. However, few researchers have examined whether messages that emphasize values associated with ecosystem services result in different policy-support or behavior-change outcomes among different audiences. We conducted a large-scale survey experiment with participants (n = 815) who resided in the United States and were recruited online via the survey platform Qualtrics. The experiment tested whether messages about watershed protection that emphasize instrumental, intrinsic, or relational values (as opposed to the information-only control message) resulted in differing support for policies or behavioral intentions related to watershed conservation. Respondents' personal characteristics had a stronger effect on conservation beliefs than the way values were framed (i.e., than treatments in the experiment). For example, income positively predicted policy support (ß = 0.07, 95% CI 0.02-0.12, p = 0.01, corrected p = 0.03). Instrumental messages decreased (SSG, tense) policy support among people who identified as politically liberal (ß = -0.75, 95% CI -1.19 to -0.30, p = 0.001, corrected p = 0.003). Over 40% of respondents selected relational values over other value types as the main reason to protect watersheds. Our results demonstrated that political orientation interacts with how the importance of conservation is framed in complex ways and that conservation practitioners might improve the effectiveness of their communications by incorporating relational values and tailoring messages to different audiences.

Aprendizajes de un Experimento con Mensajería Basada en Valores para Apoyar la Conservación de Cuencas Resumen Los profesionales de la conservación usan un lenguaje relacionado con los valores instrumentales, intrínsecos y de relación cuando comunican la importancia de la conservación, con frecuencia en relación con los servicios ambientales. Sin embargo, pocos investigadores han analizado si los mensajes que enfatizan los valores asociados con los servicios ambientales resultan en el respaldo a políticas diferentes o cambios en el comportamiento entre los diferentes públicos receptores. Realizamos un experimento de encuesta a gran escala con participantes (n = 815) residentes en los Estados Unidos reclutados mediante la plataforma en línea Qualtrics. El experimento evaluó si los mensajes sobre la protección de cuencas que resaltan los valores instrumentales, intrínsecos y de relación (contrario al mensaje-control de sólo información) llevaban a diferencias en el apoyo a las políticas o intenciones conductuales relacionadas con la conservación. Las características personales de los participantes tuvieron un efecto más importante sobre las creencias de la conservación que la manera en la que se estructuraron los valores (es decir, que los tratamientos en el experimento). Por ejemplo, el nivel de ingresos pronosticó positivamente el apoyo a las políticas (ß = 0.07, 95% CI 0.02 a 0.12, p = 0.01, corregido p = 0.03). Los mensajes instrumentales disminuyeron (SSG, tiempo) el apoyo a las políticas entre las personas identificadas como liberales políticamente (ß = −0.75, 95% CI −1.19 a −0.30, p = 0.001, corregido p = 0.003). Más de 40% de los participantes relacionaron los valores por encima de otros tipos de valores como la razón principal para proteger las cuencas. Nuestros resultados demostraron que la orientación política interactúa con cómo la importancia de la conservación se estructura de formas complejas y que quienes practican la conservación pueden incrementar la efectividad de sus comunicados si incorporan los valores de relación y ajustan los mensajes para diferentes públicos receptores.

COVID-19 and human-nature relationships: Vermonters' activities in nature and associated nonmaterial values during the pandemic.

The COVID-19 pandemic has rapidly modified Earth's social-ecological systems in many ways; here we study its impacts on human-nature interactions. We conducted an online survey focused on peoples' relationships with the non-human world during the pandemic and received valid responses from 3,204 adult residents of the state of Vermont (U.S.A.). We analyzed reported changes in outdoor activities and the values associated with human-nature relationships across geographic areas and demographic characteristics. We find that participation increased on average for some activities (foraging, gardening, hiking, jogging, photography and other art, relaxing alone, walking, and watching wildlife), and decreased for others (camping, relaxing with others). The values respondents ranked as more important during the pandemic factored into two groups, which we label as "Nurture and Recreation values" and "Inspiration and Nourishment values." Using multinomial logistic regression, we found that respondents' preferences for changes in activity engagement and value factors are statistically associated with some demographic characteristics, including geography, gender, income, and employment status during the pandemic. Our results suggest that nature may play an important role in coping during times of crisis, but that the specific interactions and associated values that people perceive as most important may vary between populations. Our findings emphasize for both emergency and natural resources planning the importance of understanding variation in how and why people interact with and benefit from nature during crises.

Reimagining the potential of Earth observations for ecosystem service assessments.

The benefits nature provides to people, called ecosystem services, are increasingly recognized and accounted for in assessments of infrastructure development, agricultural management, conservation prioritization, and sustainable sourcing. These assessments are often limited by data, however, a gap with tremendous potential to be filled through Earth observations (EO), which produce a variety of data across spatial and temporal extents and resolutions. Despite widespread recognition of this potential, in practice few ecosystem service studies use EO. Here, we identify challenges and opportunities to using EO in ecosystem service modeling and assessment. Some challenges are technical, related to data awareness, processing, and access. These challenges require systematic investment in model platforms and data management. Other challenges are more conceptual but still systemic; they are byproducts of the structure of existing ecosystem service models and addressing them requires scientific investment in solutions and tools applicable to a wide range of models and approaches. We also highlight new ways in which EO can be leveraged for ecosystem service assessments, identifying promising new areas of research. More widespread use of EO for ecosystem service assessment will only be achieved if all of these types of challenges are addressed. This will require non-traditional funding and partnering opportunities from private and public agencies to promote data exploration, sharing, and archiving. Investing in this integration will be reflected in better and more accurate ecosystem service assessments worldwide.

The importance of culture in predicting environmental behavior in middle school students on Hawai'i Island.

Researchers have investigated the factors that influence environmental behavior for decades. Two often-investigated phenomena, connectedness to nature and self-efficacy, often correlate with environmental behavior, yet researchers rarely analyze those correlations along with underlying cultural factors. We suggest that this is a substantial oversight and hypothesize that cultural factors affect environmental behavior, particularly through an interplay with the connectedness to nature and self-efficacy constructs. To test this hypothesis, we surveyed eighth-grade students on the island of Hawai'i. The instrument included items to assess connectedness to nature and self-efficacy (both frequently measured in environmental behavior studies) and multiple measures of behavior. Most of the behavior measures are commonly used in studies of environmental behavior, and one was developed in collaboration with local partners to reflect more culturally specific modes of environmental behavior. With those partners, we also developed a construct reflecting the relevance of local culture. We explored the relative influence of the more commonly investigated constructs (connectedness to nature, behavioral variables) along with the newer construct (cultural relevance). We found that, when we took those considerations into account, cultural relevance significantly predicted connectedness to nature, self-efficacy, and a commonly used behavioral measure. Our results thus suggest that many models of environmental behavior may be misspecified when they omit critical culture- and ethnicity-related factors. This may be particularly important in contexts with high cultural, racial, and ethnic diversity or in contexts where mainstream Western environmental approaches are non-dominant. Our results emphasize the importance of addressing ethnicity and culture in environmental thought and action.

Exploring dynamism of cultural ecosystems services through a review of environmental education research.

The field of cultural ecosystem services (CES) explores the non-material benefits that ecosystems provide to people. Human perceptions and valuations change, for many reasons and in many ways; research on CES, however, rarely accounts for this dynamism. In an almost entirely separate academic world, research on environmental education (EE) explores how EE programming affects peoples' attitudes and values toward the natural world. In this review of 119 EE research publications, we explore whether CES (and the adjacent concept of relational values) can be dynamic. We approach this via two lines of inquiry that explore whether EE may instigate this change. First, we investigate whether the EE community measures (and tries to affect) CES-related outcomes. Second, we ask: Has EE research detected changes in CES-related outcomes? We find the EE programs measure many CES outcomes (e.g., aesthetic appreciation, social connectedness), and that in most cases studies observe increases in these outcomes after EE experiences.

Environmental Behavior's Dirty Secret: The Prevalence of Waste Management in Discussions of Environmental Concern and Action.

Humankind and the planet face many thorny environmentally related challenges that require a range of responses, including changing behaviors related to transportation, eating habits, purchasing, and myriad other aspects of life. Using data from a 1201-person survey and 14 Community Listening Sessions (CLSs), we explore people's perceptions of and actions taken to protect the environment. Our data indicate a striking prevalence of waste management-related actions. Survey respondents described actions and concerns related to trash, recycling, and composting as the most common environmental behaviors; similarly, participants in CLSs discussed waste-related topics, for which we did not prompt, as frequently as those topics for which we specifically prompted. Explanations for this prevalence emerging from the data include (1) the nature of waste-related behaviors (concrete, supported by infrastructure, simple, compatible with lifestyle); (2) norms and social dynamics (family interactions, feelings of belonging/participation, government policy); and (3) internal psychological processes (internalized norms and environmental concern). We also found that many waste-related discussions were relatively superficial, focusing on immediate waste-related issues (e.g., litter or recycling) rather than larger issues such as consumption. Our results may provide insight into future efforts to encourage pro-environmental behavior. Given that most pro-environmental behavior involves tasks more complex and lifestyle-changing than those related to simple aspects of waste management, we suggest focusing on the latter two intertwined categories that our data suggest are important: encouraging social dynamics and related development of norms concerning environmental behavior (category 2), and fostering internalized norms and environmental concern (category 3).

A protocol for eliciting nonmaterial values through a cultural ecosystem services frame.

Stakeholders' nonmaterial desires, needs, and values often critically influence the success of conservation projects. These considerations are challenging to articulate and characterize, resulting in their limited uptake in management and policy. We devised an interview protocol designed to enhance understanding of cultural ecosystem services (CES). The protocol begins with discussion of ecosystem-related activities (e.g., recreation, hunting) and management and then addresses CES, prompting for values encompassing concepts identified in the Millennium Ecosystem Assessment (2005) and explored in other CES research. We piloted the protocol in Hawaii and British Columbia. In each location, we interviewed 30 individuals from diverse backgrounds. We analyzed results from the 2 locations to determine the effectiveness of the interview protocol in elucidating nonmaterial values. The qualitative and spatial components of the protocol helped characterize cultural, social, and ethical values associated with ecosystems in multiple ways. Maps and situational, or vignette-like, questions helped respondents articulate difficult-to-discuss values. Open-ended prompts allowed respondents to express a diversity of ecosystem-related values and proved sufficiently flexible for interviewees to communicate values for which the protocol did not explicitly probe. Finally, the results suggest that certain values, those mentioned frequently throughout the interview, are particularly salient for particular populations. The protocol can provide efficient, contextual, and place-based data on the importance of particular ecosystem attributes for human well-being. Qualitative data are complementary to quantitative and spatial assessments in the comprehensive representation of people's values pertaining to ecosystems, and this protocol may assist in incorporating values frequently overlooked in decision making processes.

Forest restoration and parasitoid wasp communities in montane Hawai'i.

Globally, most restoration efforts focus on re-creating the physical structure (flora or physical features) of a target ecosystem with the assumption that other ecosystem components will follow. Here we investigate that assumption by documenting biogeographical patterns in an important invertebrate taxon, the parasitoid wasp family Ichneumonidae, in a recently reforested Hawaiian landscape. Specifically, we test the influence of (1) planting configurations (corridors versus patches), (2) vegetation age, (3) distance from mature native forest, (4) surrounding tree cover, and (5) plant community composition on ichneumonid richness, abundance, and composition. We sampled over 7,000 wasps, 96.5% of which were not native to Hawai'i. We found greater relative richness and abundance of ichneumonids, and substantially different communities, in restored areas compared to mature forest and abandoned pasturelands. Non-native ichneumonids drive these differences; restored areas and native forest did not differ in native ichneumonid abundance. Among restored areas, ichneumonid communities did not differ by planting age or configuration. As tree cover increased within 120 m of a sampling point, ichneumonid community composition increasingly resembled that found in native forest. Similarly, native ichneumonid abundance increased with proximity to native forest. Our results suggest that restoration plantings, if situated near target forest ecosystems and in areas with higher local tree cover, can facilitate restoration of native fauna even in a highly invaded system.

The challenges of incorporating cultural ecosystem services into environmental assessment.

The ecosystem services concept is used to make explicit the diverse benefits ecosystems provide to people, with the goal of improving assessment and, ultimately, decision-making. Alongside material benefits such as natural resources (e.g., clean water, timber), this concept includes-through the 'cultural' category of ecosystem services-diverse non-material benefits that people obtain through interactions with ecosystems (e.g., spiritual inspiration, cultural identity, recreation). Despite the longstanding focus of ecosystem services research on measurement, most cultural ecosystem services have defined measurement and inclusion alongside other more 'material' services. This gap in measurement of cultural ecosystem services is a product of several perceived problems, some of which are not real problems and some of which can be mitigated or even solved without undue difficulty. Because of the fractured nature of the literature, these problems continue to plague the discussion of cultural services. In this paper we discuss several such problems, which although they have been addressed singly, have not been brought together in a single discussion. There is a need for a single, accessible treatment of the importance and feasibility of integrating cultural ecosystem services alongside others.
