Tourists' valuation of nature in protected areas: A systematic review.

In the face of biodiversity loss, it is crucial to broaden the arguments for conservation of protected areas by acknowledging diverse values of nature. We systematically reviewed empirical studies to investigate tourists' values of nature in protected areas over time and across regions. To do so, we explored (1) the main ecological and social characteristics of the case studies; (2) methodological approaches; and (3) value types. Based on the review of 152 articles, we found that economic valuation has received the most scientific attention, while socio-cultural valuation approaches have recently increased. Values were primarily elicited and analyzed quantitatively and in monetary metrics, although valuation methods and frameworks have diversified over the past two decades. However, considering the role of valuation methods and frameworks as value-articulating institutions, we suggest that future research on nature valuation also applies qualitative and non-monetary methods, elicits diverse values, and conducts plural valuation.

A feminist ethos for caring knowledge production in transdisciplinary sustainability science.

Transdisciplinary Sustainability Science has emerged as a viable answer to current sustainability crises with the aim to strengthen collaborative knowledge production. To expand its transformative potential, we argue that Transdisciplinary Sustainability Science needs to thoroughly engage with questions of unequal power relations and hierarchical scientific constructs. Drawing on the work of the feminist philosopher María Puig de la Bellacasa, we examine a feminist ethos of care which might provide useful guidance for sustainability researchers who are interested in generating critical-emancipatory knowledge. A feminist ethos of care is constituted by three interrelated modes of knowledge production: (1) thinking-with, (2) dissenting-within and (3) thinking-for. These modes of thinking and knowing enrich knowledge co-production in Transdisciplinary Sustainability Science by (i) embracing relational ontologies, (ii) relating to the 'other than human', (iii) cultivating caring academic cultures, (iv) taking care of non-academic research partners, (v) engaging with conflict and difference, (vi) interrogating positionalities and power relations through reflexivity, (vii) building upon marginalised knowledges via feminist standpoints and (viii) countering epistemic violence within and beyond academia. With our paper, we aim to make a specific feminist contribution to the field of Transdisciplinary Sustainability Science and emphasise its potentials to advance this field.

Leverage points for addressing marine and coastal pollution: A review.

Despite an increasing understanding of the issue of marine pollution, humanity continues on a largely unsustainable trajectory. This study aimed to identify and classify the range of scientific studies and interventions to address coastal and marine pollution. We reviewed 2417 scientific papers published between 2000 and 2018, 741 of which we analysed in depth. To classify pollution interventions, we applied the systems-oriented concept of leverage points, which focuses on places to intervene in complex systems to bring about systemic change. We found that pollution is largely studied as a technical problem and fewer studies engage with pollution as a systemic social-ecological issue. While recognising the importance of technical solutions, we highlight the need to focus on under-researched areas pertaining to the deeper drivers of pollution (e.g. institutions, values) which are needed to fundamentally alter system trajectories.

Leverage points to foster human-nature connectedness in cultural landscapes.

Calls for a reconnection to nature and the biosphere have been growing louder over the last decades. Cultural landscapes are rapidly changing, posing a threat to ecosystems and biodiversity, but also to human-nature connections. Human-nature connectedness may be a potential lever to shift the unsustainable trajectory that we are currently proceeding, but is also negatively influenced by it. To concretize the call for a reconnection to nature, we used the leverage points perspective on five empirical case studies with focus on human-nature connectedness. Based on the synthesis of our yearlong work, in this perspective paper, we propose four leverage points to foster a sustainability transformation: (1) maintain and enhance the structural diversity of landscapes, (2) maintain and enhance economically and ecologically sustainable small-scale agriculture, (3) strengthen sense of place and (4) strengthen sense of agency in actors. Intervening in these leverage points could be effective to foster human-nature connectedness and ultimately contribute towards a sustainable trajectory. We further argue that the interconnection between leverage points is equally important as their systemic depth.

Participatory scenario planning to facilitate human-wildlife coexistence.

Fostering human-wildlife coexistence requires transdisciplinary approaches that integrate multiple sectors, account for complexity and uncertainty, and ensure stakeholder participation. One such approach is participatory scenario planning, but to date, this approach has not been used in human-wildlife contexts. We devised a template for how participatory scenario planning can be applied to identify potential avenues for improving human-wildlife coexistence. We drew on 3 conceptual building blocks, namely the SEEDS framework, the notion of critical uncertainties, and the three-horizons technique. To illustrate the application of the proposed template, we conducted a case study in the Zambezi region of Namibia. We held 5 multistakeholder workshops that involved local people as well as numerous nongovernment and government stakeholders. We identified 14 important wildlife species that generated multiple services and disservices. The subsequent benefits and burdens, in turn, were inequitably distributed among stakeholders. Government actors played particularly influential roles in shaping social-ecological outcomes. We identified 2 critical uncertainties for the future: the nature of governance (fragmented vs. collaborative) and the type of wildlife economy (hunting vs. photography based). Considering these uncertainties resulted in 4 plausible scenarios describing future human-wildlife coexistence. Stakeholders did not agree on a single preferred scenario, but nevertheless agreed on several high-priority strategies. Bridging the remaining gaps among actors will require ongoing deliberation among stakeholders. Navigating the complex challenges posed by living with wildlife requires moving beyond disciplinary approaches. To that end, our template could prove useful in many landscapes around the world.

Planeación de Escenarios Participativos para Facilitar la Coexistencia Humano-Fauna Resumen El fomento a la coexistencia humano-fauna requiere de estrategias transdisciplinarias que integren a múltiples sectores, consideren la complejidad y la incertidumbre y aseguren la participación de los actores. Una de estas estrategias es la planeación de escenarios de participación, pero hasta la fecha no se ha usado dentro de contextos humano-fauna. Diseñamos un modelo para poder aplicar la planeación de escenarios participativos para identificar vías potenciales para mejorar la coexistencia humano-fauna. Nos basamos en tres componentes conceptuales básicos, principalmente el marco de trabajo SEEDS, la noción de incertidumbres críticas y la técnica de los tres horizontes. Para ejemplificar la aplicación del modelo propuesto, realizamos un estudio de caso en la región del Zambeze en Namibia. Realizamos cinco talleres con múltiples actores, los cuales involucraron a los habitantes locales y a numerosos actores gubernamentales y no gubernamentales. Identificamos 14 especies de fauna importantes que generan múltiples servicios y perjuicios. Los beneficios y problemas subsecuentes, en cambio, estaban distribuidos injustamente entre los actores. Los actores gubernamentales tuvieron notablemente un papel de mucha influencia en la formación de los resultados socioecológicos. Identificamos dos incertidumbres importantes para el futuro: la naturaleza de la gestión (fragmentada versus colaborativa) y el tipo de economía faunística (basada en la cacería versus basada en la fotografía). Cuando consideramos estas incertidumbres, obtuvimos como resultado cuatro escenarios posibles descriptivos de la coexistencia humano-fauna en el futuro. Los actores no estuvieron de acuerdo sobre ningún escenario preferido; sin embargo, sí coincidieron en varias estrategias de prioridad alta. El cierre de las brechas restantes requerirá de una continua deliberación entre los actores. La navegación de los retos complejos generados por la convivencia con la fauna requiere ir más allá de las estrategias disciplinarias. Para este fin, nuestro modelo podría ser útil en muchos paisajes alrededor del mundo.

Plastics in our ocean as transdisciplinary challenge.

This conference report summarizes the current challenges of researching microplastics pollution in the ocean as debated by international experts and stakeholders at a workshop held in San Sebastián, Spain, 1-2 October 2019. The transdisciplinary, co-learning approach of this report stressed the need to incorporate multiple perspective in solving the problem of microplastics and resulted in three proposed actions: (i) filtering microplastics from waste waters; (ii) mandatory ecolabels on plastic products packages; and (iii) circular economy of packaging plastics.

Making the UN Decade on Ecosystem Restoration a Social-Ecological Endeavour.

The United Nations (UN) recently declared 2021 to 2030 the Decade on Ecosystem Restoration. Against this background, we review recent social-ecological systems research and summarize key themes that could help to improve ecosystem restoration in dynamic social contexts. The themes relate to resilience and adaptability, ecosystem stewardship and navigation of change, relational values, the coevolution of human and ecological systems, long-range social-ecological connections, and leverage points for transformation. We recommend two cross-cutting new research foci; namely: (i) post hoc cross-sectional assessments of social-ecological restoration projects; and (ii) transdisciplinary social-ecological 'living labs' that accompany new restoration projects as they unfold. With global agendas increasingly taking a social-ecological perspective, the recasting of ecosystem restoration as a social-ecological endeavor offers exciting new opportunities for both research and practice.
