- Coral reefs worldwide face an uncertain future with many reefs reported to transition from being dominated by corals to macroalgae. However, given the complexity and diversity of the ecosystem, research on how regimes vary spatially and temporally is needed. Reef regimes are most often characterised by their benthic components; however, complex dynamics are associated with losses and gains in both fish and benthic assemblages. To capture this complexity, we synthesised 3,345 surveys from Hawai'i to define reef regimes in terms of both fish and benthic assemblages. Model-based clustering revealed five distinct regimes that varied ecologically, and were spatially heterogeneous by island, depth and exposure. We identified a regime characteristic of a degraded state with low coral cover and fish biomass, one that had low coral but high fish biomass, as well as three other regimes that varied significantly in their ecology but were previously considered a single coral dominated regime. Analyses of time series data reflected complex system dynamics, with multiple transitions among regimes that were a function of both local and global stressors. Coupling fish and benthic communities into reef regimes to capture complex dynamics holds promise for monitoring reef change and guiding ecosystem-based management of coral reefs.

- Coral reefs worldwide face unprecedented cumulative anthropogenic effects of interacting local human pressures, global climate change and distal social processes. Reefs are also bound by the natural biophysical environment within which they exist. In this context, a key challenge for effective management is understanding how anthropogenic and biophysical conditions interact to drive distinct coral reef configurations. Here, we use machine learning to conduct explanatory predictions on reef ecosystems defined by both fish and benthic communities. Drawing on the most spatially extensive dataset available across the Hawaiian archipelago-20 anthropogenic and biophysical predictors over 620 survey sites-we model the occurrence of four distinct reef regimes and provide a novel approach to quantify the relative influence of human and environmental variables in shaping reef ecosystems. Our findings highlight the nuances of what underpins different coral reef regimes, the overwhelming importance of biophysical predictors and how a reef's natural setting may either expand or narrow the opportunity space for management interventions. The methods developed through this study can help inform reef practitioners and hold promises for replication across a broad range of ecosystems.

What factors enable social-ecological transformative potential? The role of learning practices, empowerment, and networking
- 2023

Ingår i: Ecology and Society. - 1708-3087. ; 28:2

Tidskriftsartikel (refereegranskat)abstract
- Achieving sustainability in the Anthropocene requires radical changes to how human societies operate. The Seeds of Good Anthropocenes (SOGA) project has identified a diverse set of existing initiatives, called “seeds,” that have the potential to catalyze transformations toward more sustainable pathways. However, the empirical investigation of factors and conditions that enable successful sustainability transformations across multiple cases has been scarce. Building on a review of existing theoretical and empirical research, we developed a theoretical framework for assessing three features identified as important to transformative potential of innovative social-ecological initiatives: (1) learning practices, (2) empowerment, and (3) networking. We applied this framework to a set of African-led and Africa-related initiatives that we selected from the SOGA database that were divided into initiatives with more or less transformative potential. We coded the presence or absence of features relating to the theoretical framework using secondary data, and then compared the initiatives using qualitative comparative analysis (QCA). This analysis revealed that of the three features tested, Networking emerged as the most important feature for transformative potential when compared amongst cases. By developing and testing a framework for the comparison of cases we provide a basis for future comparative work to further identify and test properties of cases that enable transformation.

Key features for more successful place-based sustainability research on social-ecological systems : a Programme on Ecosystem Change and Society (PECS) perspective
- 2017

Ingår i: Ecology and Society. - 1708-3087. ; 22:1

Tidskriftsartikel (refereegranskat)abstract
- The emerging discipline of sustainability science is focused explicitly on the dynamic interactions between nature and society and is committed to research that spans multiple scales and can support transitions toward greater sustainability. Because a growing body of place-based social-ecological sustainability research (PBSESR) has emerged in recent decades, there is a growing need to understand better how to maximize the effectiveness of this work. The Programme on Ecosystem Change and Society (PECS) provides a unique opportunity for synthesizing insights gained from this research community on key features that may contribute to the relative success of PBSESR. We surveyed the leaders of PECS-affiliated projects using a combination of open, closed, and semistructured questions to identify which features of a research project are perceived to contribute to successful research design and implementation. We assessed six types of research features: problem orientation, research team, and contextual, conceptual, methodological, and evaluative features. We examined the desirable and undesirable aspects of each feature, the enabling factors and obstacles associated with project implementation, and asked respondents to assess the performance of their own projects in relation to these features. Responses were obtained from 25 projects working in 42 social-ecological study cases within 25 countries. Factors that contribute to the overall success of PBSESR included: explicitly addressing integrated social-ecological systems; a focus on solutionand transformation-oriented research; adaptation of studies to their local context; trusted, long-term, and frequent engagement with stakeholders and partners; and an early definition of the purpose and scope of research. Factors that hindered the success of PBSESR included: the complexities inherent to social-ecological systems, the imposition of particular epistemologies and methods on the wider research group, the need for long periods of time to initiate and conduct this kind of research, and power asymmetries both within the research team and among stakeholders. In the self-assessment exercise, performance relating to team and context-related features was ranked higher than performance relating to methodological, evaluation, and problem orientation features. We discuss how these insights are relevant for balancing place-based and global perspectives in sustainability science, fostering more rapid progress toward inter-and transdisciplinary integration, redefining and measuring the success of PBSESR, and facing the challenges of academic and research funding institutions. These results highlight the valuable opportunity that the PECS community provides in helping build a community of practice for PBSESR.

Tidskriftsartikel (refereegranskat)abstract
- The scale, rate, and intensity of humans' environmental impact has engendered broad discussion about how to find plausible pathways of development that hold the most promise for fostering a better future in the Anthropocene. However, the dominance of dystopian visions of irreversible environmental degradation and societal collapse, along with overly optimistic utopias and business-as-usual scenarios that lack insight and innovation, frustrate progress. Here, we present a novel approach to thinking about the future that builds on experiences drawn from a diversity of practices, worldviews, values, and regions that could accelerate the adoption of pathways to transformative change (change that goes beyond incremental improvements). Using an analysis of 100 initiatives, or seeds of a good Anthropocene, we find that emphasizing hopeful elements of existing practice offers the opportunity to: (1) understand the values and features that constitute a good Anthropocene, (2) determine the processes that lead to the emergence and growth of initiatives that fundamentally change human-environmental relationships, and (3) generate creative, bottom-up scenarios that feature well-articulated pathways toward a more positive future.

Tidskriftsartikel (refereegranskat)abstract
- The United Nations Decade of Ocean Science for Sustainable Development 2021-2030 (the 'Ocean Decade') is poised to stimulate new cooperation for ocean science, but makes no mention of conflict or peace. We contend that this is a missed opportunity, and use an environmental peacebuilding typology to review how ocean science has historically contributed to peace. Such considerations are timely in the context of an increasingly complex and multidimensional ocean risk landscape, due among other things to unprecedented growth in the extent and intensity of ocean uses, and increasing conflict potential as the ocean becomes a more crowded and coveted place. We conclude by proposing the Ocean Decade Implementation Plan be appended to include an eighth intended outcome: 'A Peaceful Ocean'.

Masked, diluted and drowned out : how global seafood trade weakens signals from marine ecosystems

Tidskriftsartikel (refereegranskat)abstract
- Nearly 40% of seafood is traded internationally and an even bigger proportion is affected by international trade, yet scholarship on marine fisheries has focused on global trends in stocks and catches, or on dynamics of individual fisheries, with limited attention to the link between individual fisheries, global trade and distant consumers. This paper examines the usefulness of fish price as a feedback signal to consumers about the state of fisheries and marine ecosystems. We suggest that the current nature of fisheries systems and global markets prevent transmission of such price signals from source fisheries to consumers. We propose several mechanisms that combine to weaken price signals, and present one example - the North Sea cod - to show how these mechanisms can be tested. The lack of a reliable price feedback to consumers represents a challenge for sustainable fisheries governance. We therefore propose three complimentary approaches to address the missing feedback: (i) strengthening information flow through improved traceability and visibility of individual fishers to consumers, (ii) capitalizing on the changing seafood trade structures and (iii) bypassing and complementing market mechanisms by directly targeting citizens and political actors regarding marine environmental issues through publicity and information campaigns. These strategies each havelimitations and thus need to be pursued together to address the challenge of sustainability in global marine fisheries.

Building university-based boundary organisations that facilitate impacts on environmental policy and practice

Tidskriftsartikel (refereegranskat)abstract
- Responding to modern day environmental challenges for societal well-being and prosperity necessitates the integration of science into policy and practice. This has spurred the devel- opment of novel institutional structures among research organisations aimed at enhancing the impact of environmental science on policy and practice. However, such initiatives are seldom evaluated and even in cases where evaluations are undertaken, the results are rarely made publicly available. As such there is very little empirically grounded guidance available to inform other organisations in this regard. To help address this, the aim of this study is to evaluate the Baltic Eye Project at Stockholm University – a unique team consisting of researchers from different fields, science communicators, journalists and policy analysts – working collectively to support evidence-informed decision-making relating to the sustainable management of the Baltic Sea environment. Specifically, through qualitative interviews, we (1) identify the impacts achieved by the Baltic Eye Project; (2) understand the challenges and barriers experienced throughout the Baltic Eye Project; and (3) highlight the key features that are needed within research organisations to enhance the impact of science on policy and practice. Results show that despite only operating for three years, the Baltic Eye Project has achieved demonstrable impacts on a range of levels: impacts on policy and practice, impacts to individuals working within the organisation and impacts to the broader University. We also identify a range of barriers that have limited impacts to date, such as a lack of clear goals at the establishment of the Baltic Eye Project and existing metrics of aca- demic impact (e.g. number of publications). Finally, based on the experiences of employees at the Baltic Eye Project, we identify the key organisational, individual, financial, material, practical, political, and social features of university-based boundary organisations that have impact on policy and practice. In doing so this paper provides empirically-derived guidance to help other research organisations increase their capacity to achieve tangible impacts on environmental policy and practice.

Red and green loops help uncover missing feedbacks in a coral reef social-ecological system

Tidskriftsartikel (refereegranskat)abstract
- Social-ecological systems (SES) exhibit complex cause-and-effect relationships. Capturing, interpreting, and responding to signals that indicate changes in ecosystems is key for sustainable management in SES. Breaks in this signal-response chain, when feedbacks are missing, will allow change to continue until a point when abrupt ecological surprises may occur. In these situations, societies and local ecosystems can often become uncoupled. In this paper, we demonstrate how the red loop-green loop (RL-GL) concept can be used to uncover missing feedbacks and to better understand past social-ecological dynamics. Reinstating these feedbacks in order to recouple the SES may ultimately create more sustainable systems on local scales. The RL-GL concept can uncover missing feedbacks through the characterization of SES dynamics along a spectrum of human resource dependence. Drawing on diverse qualitative and quantitative data sources, we classify SES dynamics throughout the history of Jamaican coral reefs along the RL-GL spectrum. We uncover missing feedbacks in red-loop and red-trap scenarios from around the year 600 until now. The Jamaican coral reef SES dynamics have moved between all four dynamic states described in the RL-GL concept: green loop, green trap, red loop and red trap. We then propose mechanisms to guide the current unsustainable red traps back to more sustainable green loops, involving mechanisms of seafood trade and ecological monitoring. By gradually moving away from seafood exports, Jamaica may be able to return to green-loop dynamics between the local society and their locally sourced seafood. We discuss the potential benefits and drawbacks of this proposed intervention and give indications of why an export ban may insure against future missing feedbacks and could prolong the sustainability of the Jamaican coral reef ecosystem. Our approach demonstrates how the RL-GL approach can uncover missing feedbacks in a coral reef SES, a way the concept has not been used before. We advocate for how the RL-GL concept in a feedback setting can be used to synthesize various types of data and to gain an understanding of past, present and future sustainability that can be applied in diverse social-ecological settings.

- The concept of social-ecological systems is useful for understanding the interlinked dynamics of environmental and societal change. The concept has helped facilitate: (1) increased recognition of the dependence of humanity on ecosystems; (2) improved collaboration across disciplines, and between science and society; (3) increased methodological pluralism leading to improved systems understanding; and (4) major policy frameworks considering social-ecological interactions. Despite these advances, the potential of a social-ecological systems perspective to improve sustainability outcomes has not been fully realized. Key priorities are to: (1) better understand and govern social-ecological interactions between regions; (2) pay greater attention to long-term drivers; (3) better understand the interactions among power relations, justice, and ecosystem stewardship; and (4) develop a stronger science-society interface.

Social-ecological resilience and biosphere-based sustainability science
- 2016

Ingår i: Ecology and Society. - 1708-3087. ; 21:3

Tidskriftsartikel (refereegranskat)abstract
- Humanity has emerged as a major force in the operation of the biosphere. The focus is shifting from the environment as externality to the biosphere as precondition for social justice, economic development, and sustainability. In this article, we exemplify the intertwined nature of social-ecological systems and emphasize that they operate within, and as embedded parts of the biosphere and as such coevolve with and depend on it. We regard social-ecological systems as complex adaptive systems and use a social-ecological resilience approach as a lens to address and understand their dynamics. We raise the challenge of stewardship of development in concert with the biosphere for people in diverse contexts and places as critical for long-term sustainability and dignity in human relations. Biosphere stewardship is essential, in the globalized world of interactions with the Earth system, to sustain and enhance our life-supporting environment for human well-being and future human development on Earth, hence, the need to reconnect development to the biosphere foundation and the need for a biosphere-based sustainability science.

Landscape features shape people's perception of ecosystem service supply areas

Ingår i: Ecosystem Services. - 2212-0416 .- 2212-0416. ; 64
-
Tidskriftsartikel (refereegranskat)abstract
- Landscapes have typically been produced by varied, diverse, and long-term interactions between people and nature. However, most landscape planning and ecosystem service mapping approaches focus on the biophysical aspects of landscapes rather the social. Spatial representations of people's perceptions, mental models, and local knowledge of ecosystem services can be created using participatory mapping. This study uses participatory mapping to identify how peoples' perceptions of provisioning, regulating and cultural ecosystem service supply areas coincide or mismatch with the landscapes features of two Mediterranean river basin areas in north-eastern Catalonia, Spain. We found that the random forest and geographically weighted regression techniques are able to strongly associate landscape features with stakeholders' perceptions of ecosystem supply areas. These results demonstrate that the stakeholders associate various geographic elements with different types of ecosystem service supply areas. Visible geographical features, such as a reservoir, mountains, wetlands, showed great importance in the perception of supply areas of ecosystem services, compared to ecological or biophysical indicators, when mapping and spatially associating certain benefits to ecosystem services supply areas. These findings reveal that, often, the ecological processes and dynamics of functioning of ecosystems are invisible and not fully understood. We argue that integrating these aspects into participatory landscape planning, policies and practice can make the invisible visible and, consequently, increase the understanding for a more targeted and effective management. This could allow stakeholders to better understand the ecological processes behind the visible geographic features of the landscape, fostering a shared knowledge and better environmental management outcomes.

Envisioning desirable futures in small-scale fisheries : a transdisciplinary arts-based co-creation process
- 2024
-
Ingår i: Ecology and Society. - 1708-3087. ; 29:1
-
Tidskriftsartikel (refereegranskat)abstract
- Despite the critical importance of small-scale fisheries for food security and well-being and the role of fishers as stewards of aquatic ecosystems, their future is uncertain. Tackling narratives that portray small-scale fisheries as obsolete, disparate, and inefficient requires collectively imagining and articulating new, creative, and inspiring narratives that reflect their real contributions and enable transformative futures. Drawing on a transdisciplinary country -level case study, we analyze the process and outcomes of co -creating desirable, plural, and meaningful visions of the future for small-scale fisheries in Uruguay. Using an arts -based approach and leveraging the agency of emerging innovative initiatives throughout the country, different food system actors (fish workers, chefs, entrepreneurs) and knowledge systems (local, experience -based, and scientific) were engaged in a creative visioning process. The results of this artsbased co -creation process include (1) a series of desirable visions and narratives, synthesized into an artistic boundary object; and (2) the stepping stones to a transformative space for collective reflection, learning, and action. Although the artistic boundary object has proven instrumental among multiple and diverse participants, the transformative space encouraged academic and non-academic participants to plan collective actions and to feel more confident, motivated, and optimistic about the future of small-scale fisheries in Uruguay. With this paper we provide a tool, a platform, and a roadmap to counter the dominant bleak narrative, while also communicating the elements that constitute desirable futures for small-scale fisheries in Uruguay. On a broader scale, our contribution reinforces the emerging narrative of the key role that small-scale fisheries have, and will play, in local and global food systems.

Coral reefs as novel ecosystems : embracing new futures
- 2014

Ingår i: Current Opinion in Environmental Sustainability. - : Elsevier BV. - 1877-3435 .- 1877-3443. ; 7, s. 9-14
-
Tidskriftsartikel (refereegranskat)abstract
- The composition and functions of many ecosystems are changing, giving rise to the concept of novel ecosystems. Although some coral reefs are becoming non-coral systems, others are becoming novel coral-dominated ecosystems driven principally by differential species responses to climate change and other drivers, but also due to species range shifts at higher latitudes, and in some cases introduced species. Returning many coral reefs to pristine baselines is unrealistic, whereas embracing novel futures enables more pragmatic approaches to maintaining or re-building the dominance of corals. Coral reefs are changing in unprecedented ways, providing the impetus to improve our understanding of reef compositions that may dominate in the future, explore new management approaches, assess changes in ecosystem services, and investigate how human societies can adapt and respond to novel futures.

Managing resilience to reverse phase shifts in coral reefs

Tidskriftsartikel (refereegranskat)abstract
- Both coral-dominated and degraded reef ecosystems can be resistant to change. Typically, research and management have focused on maintaining coral dominance and avoiding phase shifts to other species compositions, rather than on weakening the resilience of already degraded reefs to re-establish coral dominance. Reversing degraded coral-reef states will involve reducing local chronic drivers like fishing pressure and poor water quality. Reversals will also require management of key ecological processes - such as those performed by different functional groups of marine herbivores - that both weaken the resilience of the degraded state and strengthen the coral-dominated state. If detrimental human impacts are reduced and key ecological processes are enhanced, pulse disturbances, such as extreme weather events, and ecological variability may provide opportunities for a return to a coral-dominated state. Critically, achieving these outcomes will necessitate a diverse range of integrated approaches to alter human interactions with reef ecosystems.

Identifying multiple coral reef regimes and their drivers across the Hawaiian archipelago

Tidskriftsartikel (refereegranskat)abstract
- Loss of coral reef resilience can lead to dramatic changes in benthic structure, often called regime shifts, which significantly alter ecosystem processes and functioning. In the face of global change and increasing direct human impacts, there is an urgent need to anticipate and prevent undesirable regime shifts and, conversely, to reverse shifts in already degraded reef systems. Such challenges require a better understanding of the human and natural drivers that support or undermine different reef regimes. The Hawaiian archipelago extends across a wide gradient of natural and anthropogenic conditions and provides us a unique opportunity to investigate the relationships between multiple reef regimes, their dynamics and potential drivers. We applied a combination of exploratory ordination methods and inferential statistics to one of the most comprehensive coral reef datasets available in order to detect, visualize and define potential multiple ecosystem regimes. This study demonstrates the existence of three distinct reef regimes dominated by hard corals, turf algae or macroalgae. Results from boosted regression trees show nonlinear patterns among predictors that help to explain the occurrence of these regimes, and highlight herbivore biomass as the key driver in addition to effluent, latitude and depth.

Amplifying actions for food system transformation : insights from the Stockholm region

Ingår i: Sustainability Science. - : Springer Science and Business Media LLC. - 1862-4065 .- 1862-4057. ; 17:6, s. 2379-2395
-
Tidskriftsartikel (refereegranskat)abstract
- Food is essential to people and is one of the main ways in which people are connected to the world’s ecosystems. However, food systems often cause ecosystem degradation and produce ill-health, which has generated increasing calls to transform food systems to be more sustainable. The Swedish food system is currently undergoing substantial change. A varied set of local actors have created alternative sustainability initiatives that enact new ways of doing, thinking, and organizing. These actors can increase the transformative impact of their initiatives through multiple actions and a variety of amplification processes. We analyzed the actions adopted by 29 food initiatives active in the Stockholm region using information available online. We conducted 11 interviews to better understand the amplification processes of speeding up (i.e., accelerating impact), scaling up (i.e., influencing higher institutional levels), and scaling deep (i.e., changing values and mind-sets). Our results indicated that the initiatives mainly seek to stabilize and grow their impact while changing the awareness, values, and mind-sets of people concerning the food they consume (scaling deep). However, these approaches raise new questions about whether these actions subvert or reinforce current unsustainable and inequitable system dynamics. We suggest there are distinct steps that local and regional governments could take to support these local actors via collaborations with coordinated forms of initiatives, and fostering changes at the municipality level, but these steps require ongoing, adaptive approaches given the highly complex nature of transformative change and the risks of reinforcing current system dynamics.

Impacts of artisanal fishing on key functional groups and the potential vulnerability of coral reefs

Tidskriftsartikel (refereegranskat)abstract
- Fishing can have major impacts on the structure of coral reef ecosystems. Overfishing of herbivores is particularly detrimental, as it makes the coral system more likely to undergo shifts to macroalgal dominance in the event of coral mass mortality. Knowing when important processes, such as herbivory, are becoming brittle is important because it can provide an opportunity for managers to avoid undesirable ecosystem-level changes. This study investigates the impact of artisanal fishing on three important functional groups of herbivores (grazers, scrapers and excavators) on five coral-dominated reefs outside Zanzibar (Tanzania). There was a negative correlation between fishing pressure and fish biomass, abundance, diversity and species richness. Moreover, fishing had a negative influence on the demographic structure of functional groups, particularly excavators, manifesting itself as a skewness towards smaller individuals within populations. Artisanal fishing can have significant impacts on key functional groups of herbivorous reef fishes which may increase the vulnerability of coral reefs to undesirable ecosystem shifts.

Tidskriftsartikel (refereegranskat)abstract
- Landscapes and their management are at the center of many of the sustainability challenges that we face. Landscapes can be described as social-ecological systems shaped by a myriad of human activities and biophysical processes, interacting across space and time. Managing them sustainably requires considering this complexity. Resilience thinking offers ways to address complexity in decision-making. In this paper, we analyse the learning and impact on a diverse group of local actors from participating in a participatory resilience assessment. The assessment, focused on sustainable landscape management in the Helge a catchment, Sweden, produced concrete knowledge outputs, describing ecosystem service bundles, a future vision, conceptual system models, and a strategic action plan. Follow-up interviews indicate that the process and its outputs supported the participants' learning process and helped them to articulate complexity thinking in practice. The outputs, and the exercises to produce them, emerged as complementary in supporting this articulation. Furthermore, they helped build participants' capacity to communicate the diverse values of the landscape to others and to target leverage points more strategically. Thus, it supported the application of resilience thinking in landscape management, especially by generating learning and fostering complex adaptive systems thinking.

How on Earth? : Operationalizing the ecosystem service concept for sustainability
- 2021

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Production landscapes are at the center of many of the sustainability challenges that we face. The ecosystem service concept has risen in prominence over the last decades as a tool to support sustainable landscape management. Stewardship has been suggested as an approach that individuals and groups of actors can practice when striving for sustainability in complex situations. In this thesis, I explore how the ecosystem service concept can be used as a tool to support the stewardship practices of various local actors who are engaging in sustainable landscape management. The core of this thesis is a participatory resilience assessment conducted together with a diverse group of actors, all involved in different forms of landscape management in the Helgeå catchment in Southern Sweden. In Paper I, I describe the participatory ecosystem service bundles analysis that was part of the process. In Paper II, I describe the process as a whole and show how participating supported learning and articulation of complexity thinking. In Paper III, I compare this process with three other knowledge co-production processes from the Helgeå catchment, and trace how different theoretical approaches led to both similar and diverging ecosystem service knowledge outputs. Finally, in Paper IV, I use a photo elicitation exercise to articulate different narratives of how sense of home motivates private, non-industrial forest owners in the Helgeå catchment to engage in stewardship practice.Together, these four papers show that the ecosystem service concept can support sustainability by facilitating knowledge co-production processes about complex challenges in landscape management. In such settings, it can function as a pedagogical tool and bridging concept. For participating civil servants, ecosystem service knowledge and terminology were also used strategically when communicating with actors in their own organizations, effectively influencing their situated agency to practice stewardship. Finally, the ecosystem service concept has the potential to be useful in the dialogue between private land owners and other actors. However, some pathways to stewardship, such as those rooted in a sense for history and community, would be better represented by other, more relational human-nature conceptualizations. This means that while the operationalization of the ecosystem service concept can contribute to stewardship practices in pursuit of sustainability, there are also important limitations that need to be taken into account in each context of use.

- Addressing sustainability challenges in landscape management requires processes for co-producing usable knowledge together with those who will use that knowledge. Participatory futures methods are powerful tools for attaining such knowledge. The applications of such methods are diverse and understanding the intricacies of the knowledge co-production process is important to further develop these research practices. To improve participatory futures methods and contribute to systematic and critical reflections on methodology, we present a comparative analysis of four research projects that applied participatory futures methods in the same study area. Conducted between 2011 and 2020, these projects aimed to co-produce knowledge about the future provision of ecosystem services in the Helge a catchment area in southern Sweden. For structuring the post-hoc, self-reflexive analysis, we developed a framework dividing the knowledge co-production process into three dimensions: settings, synthesis and diffusion. We based the analysis on documentation from the projects, a two-step questionnaire to each research team, a workshop with co-authors and interviews with key participants. The comparison highlights steps in project decision-making, explicit and implicit assumptions in our respective approaches and how these assumptions informed process design in the projects. Our detailed description of the four knowledge co-production processes points to the importance of flexibility in research design, but also the necessity for researchers and other participants to adapt as the process unfolds.

- Social-ecological interactions have been shown to generate interrelated and reoccurring sets of ecosystem services, also known as ecosystem service bundles. Given the potential utility of the bundles concept, along with the recent surge in interest it is timely to reflect on the concept, its current use and potential for the future. Based on our ecosystem service bundle experience, expertise, and ecosystem service bundle analyses, we have found critical elements for advancing the utility of ecosystem service bundle concept and deepening its impact in the future. In this paper we 1) examine the different conceptualizations of the ecosystem service bundle concept; 2) show the range of benefits of using a bundles approach; 3) explore key issues for improving research on ecosystem service bundles, including indicators, scale, and drivers and relationships between ecosystem services; and 4) outline priorities for the future by facilitating comparisons of ecosystem service bundle research.
