The interplay between economics, legislative power and social influence examined through a social-ecological framework for marine ecosystems services

In the last 15 years, conservation has shifted increasingly towards perspectives based on the instrumental value of nature, where what counts is what provides benefits to humans. The ecosystem services framework embraces this vision of nature through monetary valuation of the environment to correct market failures and government distortions that hinder efficient allocation of public goods, including goods and services provided by biodiversity and ecosystems. The popularity of this approach is reflected in different countries legislation; for instance, US, EU and UK have introduced economic criteria for comparing costs and benefits of environmental policies in protecting ecosystem services.From an operational perspective, the ecosystem services framework requires ecologists to estimate how the supply of services is affected by changes in the functionality and/or the extent of ecosystems; and economists to identify how changes in the supply affect the flow of direct and indirect benefits to people. However, this approach may be simplistic when faced with the complexity of social-ecological systems. We investigated this for three different marine services: assimilative capacity of waste, coastal defense and renewable energy. We find that economic valuation could provide efficient and fair allocations in the case of assimilative capacity, but leads to social clashes between outputs generated by cost benefit analysis and citizens' expectation in the case of coastal defense. In the case of renewable energy, controversies can be generated by regulatory mechanisms that are not necessarily aligned with the interests of industry or important social groups. We conclude that there is a need to integrate perspectives arising from utilitarian allocation of resources with those involving legislation and communal values in order to reconcile conflicting interests and better sustain marine social-ecological systems.

Using Strategic Adaptive Management to Facilitate Implementation of Environmental Flow Programs in Complex Social-Ecological Systems

Freshwater resource management is becoming increasingly complex as human pressure increases on available water resources, and as more participatory transparent decision-making frameworks are being advocated within water management. Complexity is further increased when environmental flow programs are integrated into existing water management programs. Adaptive management frameworks present an obvious choice for integration and implementation of environmental flows, but have so far failed to become the dominant framework. The research presented here highlights the ability of a strategic adaptive management (SAM) approach within an environmental flow program in the Murray Darling Basin of Australia to facilitate planning and implementation of environmental flows. The SAM approach did show that adaptive management can deal with the complexities of designing and implementing environmental flows within complex social-ecological systems, but can have limitations in the long-term. The approach highlighted the importance of social processes within adaptive management, emphasizing that a focus on inclusiveness, commitment, and transparency aimed at building understanding, trust, and ownership are key processes for implementation. In this specific case study, successful implementation was achieved through structured co-design of initial programs and participatory decision-making throughout. However, the SAM approach also showed that adaptive management is vulnerable to challenges in the long-term when resources and expertize change.

A Conceptual Urban Quality Space-Place Framework: Linking Geo-Information and Quality of Life

Space and place are key concepts for understanding the functionality of social and environmental interactions. Cities are complex social-ecological systems where space–place interactions can be interpreted by means of quality of life. Firstly, we present several quality-of-life concepts that can be linked to space and place concepts. Secondly, we develop an analysis about space and place interactions, and how the social aspects, such as the sense of place, and physical aspects, such as urban spaces, are associated with quality of life and inclusive places. Thirdly, we state how the quality of life definitions of livability and life-ability are linked to the space and place concepts, and how this link can support the understanding of quality of life in cities, considering spatial thinking. Fourthly, we expand geo-information theories to a space–place approach of urban quality of life. Finally, we discuss how the developed conceptual framework can be applied to interpret the smart city. This paper contributes to the construction of new epistemologies that could support a more holistic understanding of the cities and a more social and humanistic use of geo-information and technology.

Incorporating governance into forest transition frameworks to understand and influence Cambodia's forest landscapes

Academic inquiry into forest transitions has produced a rich body of literature examining the shift from net deforestation to net reforestation at multiple land use scales. However, researchers, practitioners, and policy analysts question the utility of current forest transition theory. Does it accurately describe and provide insight into strategies to influence patterns of forest change in countries where forest cover continues to decline? Forest transition theory has provided important insights into the ‘necessary but not sufficient’ conditions for countries shifting from net deforestation to net reforestation. To advance forest transition theory, scholars should recognize forests as complex and dynamic social-ecological systems and use analytical methods that accommodate that complexity. Transdisciplinary research that incorporates a broader range of qualitative and quantitative methods and tools is required. We analyzed the historical, social, and political factors influencing forest transition pathways in Cambodia. Cambodia exhibits similar economic pre-conditions to its neighbors, which have passed through a forest transition, yet deforestation rates remain high with no indication of slowing. We found that complex governance arrangements at multiple scales negatively influences Cambodia's forest cover and development trajectory. Attempts to nurture Cambodia's forest transition will require strengthening governance and institutions across all of the natural resource sectors. Further research that incorporates governance into forest transition frameworks is required to improve policy responses for post-transition forest outcomes.

An evaluation of the interactions among household economies, human health, and wildlife hunting in the Lac Alaotra wetland complex of Madagascar

In Madagascar, wildlife conservation and human food security and nutrition are deeply interconnected as many people rely on wild foods for sustenance. The Lac Alaotra wetland complex is an ecoregion which is indispensable to both the future food security of Madagascar’s people and the conservation of its endemic wildlife. The region is Madagascar’s largest rice production area, providing thousands of tons of rice and fish to the residents of one of the world’s least food secure nations. The wetland complex also provides habitat to numerous threatened species, including two Critically Endangered mammals found only in the Lac Alaotra wetland complex. Environmental managers must understand how people affect their local environment and how the environment, in turn, affects these people, their livelihoods, and their motivations for future natural resource use. Without an adequate understanding of the complex interactions of local people and their natural environment, it will be impossible to prevent, mitigate, or adapt to future unwanted changes in this complex social-ecological system. We used health assessments of 1 953 residents and semistructured interviews of members of 485 households in 1 9 communities within the Lac Alaotra wetland complex to investigate human-environmental interactions (including current natural resource use and hunting, and how these behaviors affect local economies and human wellbeing). Our team found that, while rates of wildlife consumption were very low throughout the region, the members of 485 surveyed households ate 975 mammals in 2013, including at least 1 6 Alaotra gentle lemurs. Thirteen percent of households had consumed wildlife in 201 3 and less than 1% of hunted wildlife was sold. Employment rates and annual income were both higher than other regions in Madagascar, and food costs were comparatively low. Nevertheless, 98% of households experienced food insecurity, and coping mechanisms (e.g., reducing portion sizes) appear to disproportionately affect young children and non-working members of households. Half of households did not receive the minimum recommended kilocalories per person per day. We found high rates of child malnutrition consistent with national rural statistics. While wildlife consumption does not appear to have significant economic or health benefits in the communities in the Alaotra wetland complex, high food insecurity significantly increased the number of forest and marshland mammals eaten by households. To improve child nutrition and wildlife conservation, we recommend targeted interventions that improve food security.

Firewood Collection in South Africa: Adaptive Behavior in Social-Ecological Models

Due to the fact that the South Africa’s savanna landscapes are under changing conditions, the previously sustainable firewood collection system in rural areas has become a social-ecological factor in questions about landscape management. While the resilience of savannas in national parks such as Kruger National Park (KNP) in South Africa has been widely acknowledged in ecosystem management, the resilience of woody vegetation outside protected areas has been underappreciated. Collecting wood is the dominant source of energy for rural households, and there is an urgent need for land management to find sustainable solutions for this complex social-ecological system. However, the firewood collection scenario is only one example, and stands for all “human-ecosystem service” interactions under the topic of over-utilization, e.g., fishery, grazing, harvesting. Agent-based modeling combined with goal-oriented action planning (GOAP) can provide fresh insights into the relationship between individual needs of humans and changes in land use. At the same time, this modeling approach includes adaptive behavior under changing conditions. A firewood collection scenario was selected for a proof-of-concept comprising households, collectors, ecosystem services and firewood sites. Our results have shown that, even when it is predictable what a single human agent will do, massive up-scaling is needed in order to understand the whole complexity of social-ecological systems. Under changing conditions, such as climate and an increasing population, fair distribution of natural goods become an important issue.

Mainstreaming deliberative principles in Environmental Impact Assessment: current practice and future prospects in the Great Barrier Reef, Australia

The Great Barrier Reef (GBR) is a highly complex social-ecological system that is under pressure from a variety of human activities, including coastal development for industrial purposes. A 2012 World Heritage Committee review found that the speed and scale of large industrial developments along the GBR coast exceeded the capacity of governments to manage their impacts. Ameliorating the impacts of large developments in the GBR is likely to require changes to the Environmental Impact Assessment (EIA) processes that form the centrepiece of Australian environmental legislation. As part of this, environmental managers must find ways to ensure that EIA decisions reflect both best-available science and community concerns. It has been suggested that innovative forms of structured decision making, such as public deliberation, could democratise impact assessment decisions, and could be accommodated within existing EIA processes, but the literature on this question is predominantly theoretical. In this paper, we explore the extent to which participatory and deliberative approaches have been integrated into existing EIA processes, using data from a survey of local residents in an area of the Great Barrier Reef coast undergoing rapid industrial development. We find that current processes provide few formalised opportunities for deliberative engagement, but that the principles of deliberative democracy could provide a foundation for more robust decision making, provided that such processes are part of an adaptive strategy of review over the life of a project, combined with genuine openness on the part of proponents and regulators to accept and respond to community knowledge. We elaborate on this through discussing a series of principles to support the integration of deliberative practices into EIA decision making.

Impacts of the water framework directive on learning and knowledge practices in a Swedish catchment

Catchments are complex social-ecological systems involving multiple, and often competing, interests. Water governance and management regimes are increasingly embracing pluralistic, participatory, and holistic norms as a means to engage with issues of complexity, uncertainty, and value-conflicts. Integrated, participatory approaches are theoretically linked to improved learning amongst stakeholders across sectors and decision-making that is grounded in shared knowledge, experiences and scientific evidence. However, few studies have empirically examined the impacts of an integrated approach to learning and knowledge practices related to water resources. Here, a Swedish sub-catchment that has adopted such an approach in association with implementation of the European Water Framework Directive (WFD) is examined. Interview-based analyses show that WFD implementation has both helped and hindered learning and knowledge practices surrounding both water planning and spatial planning. Whilst communities of practice have developed in the study area, a number of important challenges remain. These include the rigid goal-orientation of the WFD, the fragmentation of knowledge caused by an over-reliance on external consultants, as well as a lack of resources to synthesise information from multiple sources. Present results raise questions regarding the efficacy of the WFD to sufficiently enable the development of learning and knowledge practices capable of handling the complexity, uncertainties and value-conflicts facing catchments in Sweden and elsewhere.

The interplay of top-down planning and adaptive self-organization in an African floodplain

Natural floodplains are complex social-ecological systems in which human livelihoods are tightly coupled with flooding dynamics. In this paper, we argue that hydraulic planning in such systems, including to mitigate extreme floods, must consider three key features of adaptive self-organizing systems in floodplains - connectivity, learning feedbacks, and rhythms - to support the resilience of floodplain communities to extreme floods. We illustrate this argument with a case study of the Logone Floodplain, Cameroon. Based on hydrological data, ethnographic research and a series of focus group interviews with floodplain villagers, we analyze the interplay of top-down planning and adaptive self-organization in response to two extreme floods in 2012 and 2015. We show that recent top-down strategies of hydraulic control in the floodplain have led to more hydraulic uncertainty for local populations, and curtailed the conditions for sustainable self-organization in the floodplain.

Seeding plants for long-term multiple ecosystem service goals

The historical management of agroecological systems, such as California's rangelands, have received criticism for a singular focus on agricultural production goals, while society has shifting expectations to the supply of multiple ecosystem services from these working landscapes. The sustainability and the multiple benefits derived from these complex social-ecological systems is increasingly threatened by weed invasion, extreme disturbance, urban development, and the impacts of a rapidly changing and increasingly variable climate. California's grasslands, oak savannas, and oak woodlands are among the most invaded ecosystems in the world. Weed eradication efforts are rarely combined with seeding on these landscapes despite support for the inclusion of the practice in a weed management program. Depending on seed mix choice, cost and long-term uncertainty, especially for native seed, is an impediment to adoption by land managers. We investigated four seeding mixes (forage annual, native perennial, exotic perennial, and exotic-native perennial) to evaluate how these treatments resist reinvasion and support the delivery of simultaneous multiple ecosystem services (invasion resistance, native richness, nitrogen fixing plants, pollinator food sources, plant community diversity, forage quality, and productivity). We found the increase of exotic and native perennial cover will drive resistance to an invading weedy summer flowering forb Centaurea solstitialis but provides a mixed response to resisting invasive annual grasses. The resistance to invasion is coupled with little tradeoff in forage productivity and quality and gains in plant diversity and native cover.

Photovoice for mobilizing insights on human well-being in complex social-ecological systems: case studies from Kenya and South Africa

Equity and sustainability in the Anthropocene: a social–ecological systems perspective on their intertwined futures

Non-technical summaryIt is no longer possible nor desirable to address the dual challenges of equity and sustainability separately. Instead, they require new thinking and approaches which recognize their interlinkages, as well as the multiple perspectives and dimensions involved. We illustrate how equity and sustainability are intertwined, and how a complex social–ecological systems lens brings together advances from across the social and natural sciences to show how (in)equity and (un)sustainability are produced by the interactions and dynamics of coupled social–ecological systems. This should help understand which possible pathways could lead to sustainable and fair futures.

Crowdsourcing conservation: The role of citizen science in securing a future for seagrass

Seagrass meadows are complex social-ecological systems. Understanding seagrass meadows demands a fresh approach integrating “the human dimension”. Citizen science is widely acknowledged for providing significant contributions to science, education, society and policy. Although the take up of citizen science in the marine environment has been slow, the need for such methods to fill vast information gaps is arguably great. Seagrass meadows are easy to access and provide an example of where citizen science is expanding. Technological developments have been pivotal to this, providing new opportunities for citizens to engage with seagrass. The increasing use of online tools has created opportunities to collect and submit as well as help process and analyse data. Citizen science has helped researchers integrate scientific and local knowledge and engage communities to implement conservation measures. Here we use a selection of examples to demonstrate how citizen science can secure a future for seagrass.

Integrated natural resource management as pathway to poverty reduction: Innovating practices, institutions and policies

Poverty has many faces and poverty reduction many pathways in different contexts. Lack of food and income interact with lack of access to water, energy, protection from floods, voice, rights and recognition. Among the pathways by which agricultural research can increase rural prosperity, integrated natural resource management deals with a complex nexus of issues, with tradeoffs among issues that are in various stages of denial, recognition, analysis, innovation, scenario synthesis and creation of platforms for (policy) change. Rather than on a portfolio of externally developed ‘solutions’ ready for adoption and use, the concept of sustainable development may primarily hinge on the strengths and weaknesses of local communities to observe, analyse, innovate, connect, organize collective action and become part of wider coalitions. ‘Boundary work’ supporting such efforts can help resolve issues in a polycentric governance context, especially where incomplete understanding and knowledge prevent potential win-win alternatives to current lose-lose conflicts to emerge. Integrated research-development approaches deal with context (‘theory of place’) and options (‘theory of change’) in multiple ways that vary from selecting sites for studying pre-defined issues to starting from whatever issue deserves prominence in a given location of interest. A knowledge-to-action linkage typology recognizes three situations of increasing complexity. In Type I more knowledge can directly lead to action by a single decision maker; in Type II more knowledge can inform tradeoff decisions, while in Type III negotiation support of multiple knowledge+multiple decision maker settings deals with a higher level of complexity. Current impact quantification can deal with the first, is challenged in the second and inadequate in the third case, dealing with complex social-ecological systems. Impact-oriented funding may focus on Type I and miss the opportunities for the larger ultimate impact of Type II and III involvements.

Exploring the Role of Management in the Coproduction of Ecosystem Services from Spanish Wooded Rangelands

The wood pastures or hardwood rangelands of the southwestern Iberian Peninsula are complex social-ecological systems created from the long-term interaction of society and the landscape. Dehesa, oak woodlands managed for grazing, cropping, and other forms of production, is the most common rangeland system and one of the most distinctive landscapes. Traditionally characterized by multifunctional low-intensity management that enhances a wide range of ecosystem services, current management has shifted from the traditional toward more intensified models. This paper assesses the coproduction of ecosystem services on dehesa properties by exploring the relationship between biophysical and sociocultural factors and dehesa management practices. Based on 42 surveys we analyze 16 quantitative indicators using multivariate techniques. The results indicate that there are four main dehesa types as defined by their characteristics and management: large heterogeneous operations with diverse products; small and homogeneous operations focused on a reduced number of products; medium-large properties focused on crop production; and midsized properties with easy public access. Management is the result of the dynamics of interacting biophysical and sociocultural factors that influence manager priorities and investments. Management decisions group around the degree of multifunctionality of the operation, the relative importance of crop production, the degree of grazing pressure in the system, and how restrictive public access policy is. We find that in the study area, interactions between all the previously mentioned elements covary consistently, generating bundles of ecosystem services associated with each of three management models based on the intensity of management.

Engaging with Human Identity in Social-Ecological Systems: A Dialectical Approach

Vexing problems of global environmental change call for better conceptual and analytical approaches for understanding human behaviors, factors influencing these behaviors, and the causal pathways through which these shape social and environmental outcomes. While human identity meanings provide key analytic objects in the interrogation of these dynamics, identity-based research has been truncated by a historic overemphasis on social factors and a lack of critical engagement with the ecological context of these processes.Adapting Giddens’s concept of structuration, we draw on recent advances in social-ecological systems scholarship and human structural ecology to propose a new conceptual approach for understanding human identity processes and their relation to social-ecological structure. Resituating the human person within complex social-ecological systems, we suggest some causal pathways through which ecological (in addition to social) elements are active in the emergence of human identity and, conversely, the ways in which identity-based behaviors interact dialectically with social-ecological structure to produce outcomes significant along both social and ecological dimensions. Finally, we explore some implications of this reframing for the interrogation of society-nature dynamics and for empirical research engaging with social-ecological change and resilience.

Collaborative Adaptive Rangeland Management Fosters Management-Science Partnerships

Rangelands of the western Great Plains of North America are complex social-ecological systems where management objectives for livestock production, grassland bird conservation, and vegetation structure and composition converge. The Collaborative Adaptive Rangeland Management (CARM) experiment is a 10-year collaborative adaptive management (CAM) project initiated in 2012 that is aimed at fostering science-management partnerships and data-driven rangeland management through a participatory, multistakeholder approach. This study evaluates the decision-making process that emerged from the first 4 yr of CARM. Our objectives were to 1) document how diverse stakeholder experiences, epistemologies, and resulting knowledge contributed to the CARM project, 2) evaluate how coproduced knowledge informed management decision making through three grazing seasons, and 3) explore the implications of participation in the CARM project for rangeland stakeholders. We evaluated management decision making as representatives from government agencies and conservation nongovernmental organizations, ranchers, and interdisciplinary researchers worked within the CARM experiment to 1) prioritize desired ecosystem services; 2) determine objectives; 3) set stocking rates, criteria for livestock movement among pastures, and vegetation treatments; and 4) select monitoring techniques that would inform decision making. For this paper, we analyzed meeting transcripts, interviews, and focus group data related to stakeholder group decision making. We find two key lessons from the CARM project. First, the CAM process makes visible, but does not reconcile differences between, stakeholder experiences and ways of knowing about complex rangeland systems. Second, social learning in CAM is contingent on the development of trust among stakeholder and researcher groups. We suggest future CAM efforts should 1) make direct efforts to share and acknowledge managers’ different rangeland management experiences, epistemologies, and knowledge and 2) involve long-term research commitment in time and funding to social, as well as experimental, processes that promote trust building among stakeholders and researchers over time.

Revealing Adaptive Management of Environmental Flows

Managers of land, water, and biodiversity are working with increasingly complex social ecological systems with high uncertainty. Adaptive management (learning from doing) is an ideal approach for working with this complexity. The competing social and environmental demands for water have prompted interest in freshwater adaptive management, but its success and uptake appear to be slow. Some of the perceived "failure" of adaptive management may reflect the way success is conceived and measured; learning, rarely used as an indicator of success, is narrowly defined when it is. In this paper, we document the process of adaptive flow management in the Edward-Wakool system in the southern Murray-Darling Basin, Australia. Data are from interviews with environmental water managers, document review, and the authors' structured reflection on their experiences of adaptive management and environmental flows. Substantial learning occurred in relation to the management of environmental flows in the Edward-Wakool system, with evidence found in planning documents, water-use reports, technical reports, stakeholder committee minutes, and refereed papers, while other evidence was anecdotal. Based on this case, we suggest it may be difficult for external observers to perceive the success of large adaptive management projects because evidence of learning is dispersed across multiple documents, and learning is not necessarily considered a measure of success. We suggest that documentation and sharing of new insights, and of the processes of learning, should be resourced to facilitate social learning within the water management sector, and to help demonstrate the successes of adaptive management.

Multi-Scale Integrated Analysis of Charcoal Production in Complex Social-Ecological Systems

We propose and illustrate multi-scale integrated analysis of societal and ecosystem metabolism (MuSIASEM) as a tool to bring nexus thinking into practice. MuSIASEM studies the relations over the structural and functional components of social-ecological systems that determine the entanglement of water, energy and food flows in a complex metabolic pattern. MuSIASEM simultaneously considers various dimensions and multiple scales of analysis and therefore avoids the predicament of quantitative analysis based on reductionism (one dimension and one scale at the time). The different functional elements of society (the parts) are characterized using the concept of ‘processor’, that is, a profile of expected inputs and outputs associated with the expression of a specific function. The processors of the functional elements of the social-ecological system can be scaled-up to describe the metabolic pattern of the system as a whole, and scaled-down by considering the characteristics of its lower-level parts – i.e. the different processors associated with the structural elements required to express the specific function. An analysis of functional elements provides insight in the socio-economic factors that pose internal constraints on the development of the system. An analysis of structural elements makes it possible to study the compatibility of the system with external constraints (availability of natural resources and ecological services) in spatial terms. The usefulness of the approach is illustrated in relation to the use of charcoal in a rural village of Laos.

Water service delivery challenges in a small South African municipality: Identifying and exploring key elements and relationships in a complex social-ecological system

South Africa is a developing country undergoing social and ecological transformation. Water service delivery (i) exemplifies the challenge of improvement and transformation towards a more socially and ecologically just situation, and (ii) can usefully be viewed as a complex social-ecological system (C-SES) in the search for ‘just transitions’. Household water security problems associated with water service delivery in South Africa are recognisably intractable, multi-scaled, comprising many actors and elements and having no single solution. There is a global and South African trend towards systemic approaches to addressing such complex water challenges. However, the steps required to take a systemic approach are seldom explicit. This paper presents the analytical process of defining boundaries, identifying elements and exploring relationships between elements as the foundational step in a study of the Makana Local Municipality water service delivery C-SES in the Eastern Cape Province of South Africa. The resulting narrative and heuristics provide a clear systemic basis from which to research the emergence, practice and social learning process of a civil society organisation (Water for Dignity) seeking to confront water service delivery issues in the Makana Local Municipality.
