Research on vulnerability and adaptation in social-ecological systems (SES) has largely centered on climate change and associated biophysical stressors. Key implications of this are twofold. First, there has been limited engagement with the impacts of social drivers of change on communities and linked SES. Second, the focus on climate effects often assumes slower drivers of change and fails to differentiate the implications of change occurring at different timescales. This has resulted in a body of SES scholarship that is under-theorized in terms of how communities experience and respond to fast versus slow change. Yet, social and economic processes at global scales increasingly emerge as ‘shocks’ for local systems, driving rapid and often surprising forms of change distinct from and yet interacting with the impacts of slow, ongoing ‘trends’. This research seeks to understand the nature and impacts of social shocks as opposed to or in concert with trends through the lens of a qualitative case study of a coastal community in Mexico, where demand from international seafood markets has spurred rapid development of a sea cucumber fishery. Specifically, we examined what different social-ecological changes are being experienced by the community, how the impacts of the sea cucumber fishery are distinct from and interacting with slower ongoing trends and how these processes are affecting system vulnerability, adaptations and adaptive capacity. We begin by proposing a novel framework for conceptualizing impacts on social systems, as comprised of structures, functions, and feedbacks. Our results illustrate how the rapid-onset of this fishery has driven dramatic changes in the community. New challenges such as the ‘gold-rush-style’ arrival of new actors, money, and livelihoods, the rapid over-exploitation of fish stocks, and increases in poaching and armed violence have emerged, exacerbating pressures from ongoing trends in immigration, overfishing and tourism development. We argue that there is a need to better understand and differentiate the social and ecological implications of shocks, which present novel challenges for the vulnerability and adaptive capacity of communities and the sustainability of marine ecosystems.  相似文献

Seafood is an essential source of protein globally. As its demand continues to rise, balancing food security and the health of marine ecosystems has become a pressing challenge. Ecosystem-based fisheries management (EBFM) has been adopted by the European Union (EU) Common Fisheries Policy (CFP) to meet this challenge by accounting for the multiple interacting natural and socio-economic drivers. The CFP includes both the implementation of regulatory measures to EU stocks and the establishment of bilateral fisheries agreements with neighbouring countries, known as sustainable fisheries partnership agreements (SFPAs). While the effects of fisheries management regulations are well acknowledged, the consequences of the SFPAs on EU ecosystems have been commonly overlooked. Here we investigate the development of the Gulf of Cadiz marine ecosystem over the last two decades and found evidence of the impact of both policy interventions. Our findings reveal the effectiveness of regulatory measures in reverting a progressively degrading ecosystem, characterised by high fishing pressure and dominance of opportunistic species, to a more stable configuration, characterised by higher biomass of small pelagics and top predators after 2005. Knock-on effects of the EU-Morocco SFPA and climate effects were detected before 2005, resulting in increased purse seine fishing effort, lower biomass of pelagic species and warmer temperatures. This southern EU marine ecosystem has been one of the latest to introduce regulations and is very exposed to fishery agreements with neighbouring Morocco. Our study highlights the importance of taking into consideration, not only the effects of in situ fisheries regulations but also the indirect implications of political agreements in the framework of EBFM.  相似文献

Small-scale fisheries in developing regions are particularly vulnerable to climate change, but the assessment of climate-induced changes and impacts are often hampered by the data poor-situation of these social-ecological systems. Based on 40 years of scientific and local ecological knowledge, we provide a coherent narrative about the effects of a marine hotspot of climate change on a small-scale fishery across different geographical and temporal scales. We applied a mixed-methods approach to assess biophysical changes, social-ecological impacts, and the incremental spectrum of actions implemented at multiple levels to increase the adaptive capacity of a small-scale clam fishery. The warming hotspot here analyzed was the fastest-warming region in the South Atlantic Ocean. Long-term changes in wind intensity and direction were also noticeable at a regional scale. Both sea surface temperature and winds showed a clear shifting pattern in the late 1990 s. These climate-related stressors determined ecosystem and targeted population changes (e.g. clam mass mortalities, slow stock recovery rates after ecological shocks, habitat narrowing), and favored harmful algal bloom-forming organisms. Climate-induced drivers also affected the human component of the social-ecological system, preventing fishers from securing a fulltime livelihood and limiting the fishery economic potential. Adaptive responses at multiple levels provided some capacity to address climate change effects, and transformative pathways are being taken to adapt to climate-induced changes over the long-term. Transformative changes were fostered by the local perception of environmental change, shared narratives, sustained scientific monitoring programs, and the interaction between knowledge systems, facilitated by a bridging organization within a broader process of governance transformation. The combination of autonomous adaptations (based on linking social capital and fishery leaders agency) and government-led adaptations were essential to face the challenges imposed by climate change. Our results serve as a learning platform to anticipate threats and envision solutions to a wide range of small-scale fisheries in fast-warming regions worldwide.  相似文献

Young stakeholders are key actors in social-ecological systems, who have the capacity to be agents of sustainability transformation but are also at high risk of exclusion in the unfolding of global change challenges. Despite the focus of sustainability on future generations, there has been little research effort aimed at understanding young actors’ roles as biosphere stewards. In this work we investigate how young stakeholders perceive and participate in the implementation of sustainability objectives in 74 Biosphere Reserves of the United Nations Educational, Scientific and Cultural Organization’s (UNESCO) the Man and the Biosphere (MAB) Programme across 83 countries, through participatory group workshops, individual surveys and grey literature review. We explore to what extent youth perceptions are aligned or not with current understandings of Biosphere Reserves and how young stakeholders are acting in pursuit of Biosphere Reserve objectives. We find that young stakeholders have a comprehensive understanding of the opportunities and challenges faced by environmental governance, such as resilience and adaptation to global change and the governance challenges of implementing adaptive co-management and increasing stakeholder participation. We also show that young stakeholders can be active participants in a wide range of activities that contribute to achieving conservation and development goals in their territories. They are particularly concerned with youth participation within all levels of Biosphere Reserve functioning and with the creation of sustainable livelihood opportunities that will allow future generations to remain in their native territories. Our study provides evidence of the importance of young stakeholder knowledge and perspectives as central actors in conservation and development initiatives, like Biosphere Reserves, and of the need to increase young stakeholder integration and participation within environmental governance.  相似文献

Globalization has increased the speed and flow of people, information, and commodities across space, integrating markets and increasing interdependence of geographically dispersed places worldwide. Places historically driven by largely local forces and market demands are now increasingly affected by drivers at multiple scales. Trade is particularly important in driving these changes and more fish is now exported to international markets than ever before. When small-scale fisheries are integrated into global markets, local social–ecological systems change with potentially both positive and negative impacts on livelihoods, economics and ecology, but few studies systematically investigate how and why the outcomes of market integration vary from case to case.This paper systematically assesses multiple (social, ecological, economic and institutional) local effects of market integration in cases around the world by drawing on the global environmental change syndromes approach. Furthermore, we examine the factors contributing to the syndromes observed. Our analysis identifies three distinct social–ecological syndromes associated with international seafood trade. Results suggest that the presence of strong and well-enforced institutions is the principal factor behind the syndrome characterized by sustained fish stocks, while a combination of weak institutions, patron–client relationships, high demand from China and highly vulnerable target species explain the other two syndromes distinguished by declining stocks, conflict and debt among fishers.A key finding is that the factors emerging as important for explaining the different syndromes derive from different scales (e.g. local market structures vs distant market characteristics), indicating a need for multi-level governance approaches to deal with the effects of market integration. Furthermore, the meta-analysis shows that each syndrome encompasses fisheries from multiple continents. This suggests that the increasingly global nature of the seafood trade appears to be driving local dynamics by creating similar conditions for vulnerabilities in localities around the world, lending support to the notion of tele-connectivity across geographic space.  相似文献

Environmental sustainability is a major challenge for cotton production in Sub-Saharan Africa (SSA). The creation of voluntary certification programs is an effort aimed at finding new ways to influence corporate conduct along supply chains. This article contributes novelty and insight on cotton certification in SSA by exploring the most relevant programs in detail with regard to the demands of international non-governmental organizations (NGOs). We selected the five most central NGOs dedicated to environmental sustainability in agriculture: Friends of the Earth (FoE), Greenpeace, Oxfam, Pesticide Action Network (PAN), and World Wildlife Fund (WWF). After identifying these NGOs’ demands regarding pesticides, fertilizers and genetically modified (GM) cotton, we analyzed the requirements of the four most dominant programs certifying SSA cotton cultivation: the Better Cotton Initiative (BCI), Cotton made in Africa (CmiA), the EU Organic Regulation and Fairtrade Labelling Organization (FLO). The results of our document analysis are bolstered by semi-structured interviews with stakeholders on NGOs’ stances and roles in standard setting and implementation. We find that the EU Organic Regulation scores best in terms of environmental sustainability. Those programs in which NGOs actively participate are less ambitious compared to the public standard. Therefore, we conclude that, if NGOs maintain their commitment to multi-stakeholder initiatives, they risk contributing to ‘greenwashing’ corporate conduct by mobilizing consumer support for labelling programs that actually fall behind existing public regulation on organic certification.  相似文献

Global visions of environmental change consider gender equality to be a foundation of sustainable social-ecological systems. Similarly, social-ecological systems frameworks position gender equality as both a precursor to, and a product of, system sustainability. Yet, the degree to which gender equality is being advanced through social-ecological systems change is uncertain. We use the case of small-scale fisheries in the Pacific Islands region to explore the proposition that different social-ecological narratives: (1) ecological, (2) social-ecological, and (3) social, shape the gender equality priorities, intentions and impacts of implementing organizations. We conducted interviews with regional and national fisheries experts (n = 71) and analyzed gender commitments made within policies (n = 29) that influence small-scale fisheries. To explore these data, we developed a ‘Tinker-Tailor-Transform’ gender assessment typology. We find that implementing organizations aligned with the social-ecological and social narratives considered social (i.e., human-centric) goals to be equally or more important than ecological (i.e., eco-centric) goals. Yet in action, gender equality was pursued instrumentally to achieve ecological goals and/or shallow project performance targets. These results highlight that although commitments to gender equality were common, when operationalized commitments become diluted and reoriented. Across all three narratives, organizations mostly ‘Tinkered’ with gender equality in impact, for example, including more women in spaces that otherwise tended to be dominated by men. Impacts predominately focused on the individual (i.e., changing women) rather than driving communal-to-societal level change. We discuss three interrelated opportunities for organizations in applying the ‘Tinker-Tailor-Transform’ assessment typology, including its utility to assist organizations to orient toward intrinsic goals; challenge or reconfigure system attributes that perpetuate gender inequalities; and consciously interrogate discursive positions and beliefs to unsettle habituated policies, initiatives and theories of change.  相似文献

A bioeconomic model of key fisheries of the Barents Sea is run with scenarios generated by an earth system model of intermediate complexity to assess how the Barents Sea fisheries of cod (Gadus morhua) and capelin (Mallotus villosus) are affected by changes in the Atlantic thermohaline circulation (THC) arising from anthropogenic climate change. Changes in hydrographic conditions have an impact on recruitment success and survival rates, which constitute a lasting effect on the stocks. The economic development of the fisheries is determined for the 21st century, considering a purely stock size based and a coupled stock size-hydrography based harvesting strategy. Results show that a substantial weakening of the THC leads to impaired cod stock development, causing the associated fishery to become unprofitable in the long run. Simultaneous improvements in capelin stock development help the capelin fishery, but are insufficient to offset the losses incurred by the cod fishery. A comparison of harvest strategies reveals that in times of high variability in stock development, coupled stock size-hydrography based management leads to more stable economic results of these fisheries than the stock size based fishing strategy.  相似文献

The Code of Conduct for Responsible Fisheries developed in 1995 by the Food and Agriculture Organization (FAO) of the United Nations includes a set of recommendations for reducing the negative impacts of fishing activities on marine ecosystems. The Code is widely believed to be an important tool for fisheries management and, although the Code is voluntary, all stakeholders concerned with the management and development of fisheries, and conservation of fishery resources, are actively encouraged to implement it. Previous analysis at global scale showed widespread low compliance with the Code of Conduct that may be partly due to a lack of empirical support for the overall ecological benefits of adhering to the Code. Here we evaluated these ecological effects by comparing compliance with the Code to changes in five ecological indicators that quantify the ecosystem effects of fishing. We used the loss in production index and the related probability of sustainable fishing index, the mean trophic level of the catch, total catches, and the primary production required to sustain the catch. We also tested if regional differences and development status of countries influenced the results of ecological indicators. Results indicate that countries with higher levels of compliance with the FAO Code of Conduct in 2008 experienced a decrease in the Loss in Production index and an increase in fisheries sustainability from the 1990s to 2000s. We conclude that better implementation of the Code of Conduct may have had overall positive ecological effects with time. A significant decrease in total catch and primary production required with higher compliance was also observed. While a significant increase in ecosystem sustainability was observed after a decade of adoption of the Code at high levels of compliance, further ecosystem degradation had taken place where compliance with the Code was below a given threshold (4, from a ranking of 0–10). Therefore, since compliance with the Code is still low or very low worldwide, these results may encourage individual countries to adopt well-established fishery management measures in order to increase the ecological sustainability of marine resources.  相似文献

Climate change presents an emerging challenge to the sustainable management of tuna fisheries, and robust information is essential to ensure future sustainability. Climate and harvest affect tuna stocks, populations of non-target, dependent species and the ecosystem. To provide relevant advice we need an improved understanding of oceanic ecosystems and better data to parameterise the models that forecast the impacts of climate change. Currently ocean-wide data collection in the Pacific Ocean is primarily restricted to oceanographic data. However, the fisheries observer programs that operate in the region offer an opportunity to collect the additional information on the mid and upper trophic levels of the ecosystem that is necessary to complement this physical data, including time-series of distribution, abundance, size, composition and biological information on target and non-target species and mid trophic level organisms. These observer programs are in their infancy, with limited temporal and spatial distribution but recent international and national policy decisions have been made to expand their coverage. We identify a number of actions to initiate this monitoring including: consolidating collaborations to ensure the use of best quality data; developing consistency between sub-regional observer programmes to ensure that they meet the objectives of ecosystem monitoring; interrogating of existing time series to determine the most appropriate spatial template for monitoring; and exploring existing ecosystem models to identify suitable indicators of ecosystem status and change. The information obtained should improve capacity to develop fisheries management policies that are resilient and can be adapted to climate change.  相似文献

Faced with accelerating environmental challenges, research on social-ecological systems is increasingly focused on the need for transformative change towards sustainable stewardship of natural resources. This paper analyses the potential of rapid, large-scale socio-political change as a window of opportunity for transformative change of natural resources governance. We hypothesize that shocks at higher levels of social organization may open up opportunities for transformation of social-ecological systems into new pathways of development. However, opportunities need to be carefully navigated otherwise transformations may stall or lead the social-ecological system in undesirable directions. We investigate (i) under which circumstances socio-political change has been used by actors as a window of opportunity for initiating transformation towards sustainable natural resource governance, (ii) how the different levels of the systems (landscape, regime and niche) interact to pave the way for initiating such transformations and (iii) which key features (cognitive, structural and agency-related) get mobilized for transformation. This is achieved through analyzing natural resource governance regimes of countries that have been subject to rapid, large-scale political change: water governance in South Africa and Uzbekistan and governance of coastal fisheries in Chile. In South Africa the political and economic change of the end of the apartheid regime resulted in a transformation of the water governance regime while in Uzbekistan after the breakdown of the Soviet Union change both at the economic and political scales and within the water governance regime remained superficial. In Chile the democratization process after the Pinochet era was used to transform the governance of coastal fisheries. The paper concludes with important insight on key capacities needed to navigate transformation towards biosphere stewardship. The study also contributes to a more nuanced view on the relationship between collapse and renewal.  相似文献

This paper uses a case study to provide a critical assessment of arguments underlying market-based environmental policy. Market approaches, which rely on economic incentives and property rights to achieve environmental goals, have become increasingly popular in the past two decades. Proponents argue that market approaches should replace “command and control” regulation, which works by penalizing environmentally harmful behavior. Synthesizing results of previous research on political economy of the North Pacific pollock fishery, this paper provides evidence that contradicts hypotheses derived from the logic of market approaches. First, a lack of property rights is not the underlying cause of problems in this fishery, but instead problems were created by the institutional context of fishery development. Second, market and regulatory approaches to this fishery are not necessarily contradictory and inherently incompatible. Both markets and regulation create both economic opportunities and constraints, markets alone are not enough to protect the environment, and markets require regulation to function. Because the market approach is based on a general logic that is supposed to be universally applicable, results from this case reveal potential flaws in the market approach more generally.  相似文献

Collectively, individual adjustments to environmental and economic change can have disproportionate influence on the sustainability of the broader social–environmental system in which exposure takes place. Here we focus on the specific mechanisms by which farm-level responses to globalization and environmental change feedback to affect the sustainability and resilience of the social–environment system. We use a proposal by Lambin as an analytical frame for understanding this feedback, illustrating how information, motivation and capacity collectively structure the ways in which the actions of individuals can transform regional economies and landscapes. We draw on two Latin American case studies to illustrate the collective and synergistic implications of farmers’ livelihood and land use choices for the sensitivity of the region to future market and environmental shocks, as well as for the role of the landscapes in the global carbon cycle. We argue that the potential disconnect between individual goals of livelihood security and broader aims of system sustainability can be bridged through improved governance and attention to the role of policy, individual and collective experience, and resource constraints in adaptive choice.  相似文献

Nature-based solutions (NbS) are gaining traction in high-level, decision-making arenas as a response to global policy challenges. Claiming to be transformative and pluralistic, NbS aim to resolve societal problems through a focus on nature, which is understood to be a benign ally. This uncritical framing of nature may have unintended and inequitable consequences that undermine the emancipatory potential of NbS.In this paper, we highlight the need to pay attention to epistemic and power dimensions that tend to be hidden in NbS. We assume that nature is neither passive nor external to human society, but is instead expressed in frames (reifying modes of expression) that reflect both knowledge and power in social encounters where NbS are used. Drawing upon five cases, we analyse how particular ways of framing nature express and reinforce the power relations that structure people’s interactions. Each of the five cases relies on a nature-based frame to produce knowledge on climate adaptation, peacebuilding and justice.The analysis reveals how frames of nature are enacted in particular contexts, and how this conditions the potential for societal transformation towards sustainability and pluralistic knowledge. We demonstrate how frames of nature can constrain or enable opportunities for various groups to respond to environmental change. We discuss how the NbS paradigm might better incorporate diverse, situated knowledge and subjectivities, and conclude that this will require a more critical evaluation of NbS practice and research.  相似文献

The emergence of export markets for high-value seafood products tends to produce a predictable pattern of serial depletion of resources and social disruption in coastal communities, a phenomenon described as ‘the tragedy of the commodity’. The sea cucumber trade epitomizes these challenges, with cases of rapid growth followed by fishery collapse documented across the Indo-Pacific and the majority of assessed stocks worldwide overexploited. Is this ‘boom-bust’ sequence inevitable? We examine three cases of resistance to the sea cucumber trade from Palau, Pohnpei, and Yap. Despite the overwhelming short-term financial incentives to export, fishers, youth, elected and traditional leaders, and civil society organizations coordinated to ban the trade at its peak, using public protest, court battles, and customary and statutory law. We show that, like the tragedy of the commons, Indigenous peoples and local communities can organize to resist the tragedy of the commodity. They do so by asserting Indigenous values, rights, and institutions, recommonizing the resource and preventing fisheries collapse. These cases challenge the inevitability of the tragedy of the commodity and the narrative of poor fishers as vulnerable and disempowered.  相似文献

Resilience thinking is an important addition to the range of frameworks and approaches that can be used to understand and manage complex social–ecological systems like small-scale fisheries. However, it is yet to lead to better environmental or development outcomes for fisheries stakeholders in terms of food security, improved livelihoods and ecological sustainability. This paper takes an empirical approach by focusing on the fundamentals of resilience thinking to evaluate its usefulness in developing relevant management interventions in small-scale fisheries in the Niger River Basin in West Africa. The paper presents the outputs of a participatory assessment exercise where both fishery communities and local experts were involved at two different scales. The resilience frame used was designed to facilitate the identification of socially defined thresholds that help delineate the desirability of the current system configuration and provides a diagnosis framework that tailors management solutions to problems in local context. The analysis highlights some key contributions from resilience thinking to the challenge of diagnosis in small-scale fisheries management in developing countries, as well as important contributions that emerge from taking a pragmatic and critical approach to its application.  相似文献

Commercial marine fishing contributes significantly to the Australian economy, and has great importance for coastal communities. However, climate change presents significant challenges for Australia’s fishing industries, now and into the future. With greater use of targeted information, the fishing industry will be better placed to minimise the negative impacts and take advantage of opportunities associated with the effects of climate change. The future of the fishing industry—specifically wild capture fisheries—will depend on its ability and capacity to apply appropriate adaptation strategies for its viability and sustainability in the long-term. Knowledge regarding expected long-term changes in species distributions, improved weather and seasonal climate forecasts and their influence on target species, and better understanding of species tolerances, can inform adaptation responses. This paper provides a review of recent advances in research addressing Australia’s priorities in relation to commercial marine fisheries’ responses to current and anticipated future climate change impacts, and considers barriers and adaptation options for fisheries management over the near-term planning horizon of 5–7 years.  相似文献

There is an urgent need for developing policy-relevant future scenarios of biodiversity and ecosystem services. This paper is a milestone toward this aim focusing on open ocean fisheries. We develop five contrasting Oceanic System Pathways (OSPs), based on the existing five archetypal worlds of Shared Socioeconomic Pathways (SSPs) developed for climate change research (e.g., Nakicenovic et al., 2014 and Riahi et al., 2016). First, we specify the boundaries of the oceanic social-ecological system under focus. Second, the two major driving forces of oceanic social-ecological systems are identified in each of three domains, viz., economy, management and governance. For each OSP (OSP1 “sustainability first”, OSP2 “conventional trends”, OSP3 “dislocation”, OSP4 “global elite and inequality”, OSP5 “high tech and market”), a storyline is outlined describing the evolution of the driving forces with the corresponding SSP. Finally, we compare the different pathways of oceanic social-ecological systems by projecting them in the two-dimensional spaces defined by the driving forces, in each of the economy, management and governance domains. We expect that the OSPs will serve as a common basis for future model-based scenario studies in the context of the Intergovernmental Panel on Climate Change (IPCC) and the Intergovernmental Platform on Biodiversity and Ecosystem Services (IPBES).  相似文献

Small-scale fisheries are becoming a global social and environmental concern. The contribution of marine small-scale fisheries to global food security and coastal livelihoods, coupled with the significant challenges they face, has attracted increasing attention and aid from environmental organizations, philanthropies, and multilateral agencies over recent decades. Our study attends to the understudied role of the World Bank, the largest individual funder shaping present and future sustainability of coastal marine regions, as a key actor shaping global environmental governance paradigms. We asked how funding to the sector has changed over the last 50 years and why, outlining distinct patterns in the flow of small-scale fisheries aid and the underlying intervention models. We contextualize our quantitative analysis of aid patterns over time with qualitative interview data with bank staff, identifying underlying paradigm shifts driven by internal and external factors. More than $2.48 billion was allocated by the World Bank to marine fisheries over the last 50 years, approximately 47% (~$1.17 billion) of which was targeted to marine small-scale fisheries. Three distinct funding periods are identified: rising support to SSF from the 1970s to mid-1980s; a sharp decline in funding in the mid-to-late 1980s and low levels of funding throughout the 1990s; and a steady return to funding SSF in the mid-2000s up to the present. Over time, Bank-funded interventions shifted from pure economic development in the earlier era, to an emphasis on governance and multi-dimensional environmental goals in the recent period. To understand why, we used key-informant interviews to unpack major internal drivers: internal staff changes and presence of key individuals, the decentralization and recentralization of decision-making, and the organization’s shifting emphasis from traditional economic growth to multi-dimensional objectives of poverty reduction, among others. External drivers behind funding and paradigm shifts included pressure from the environmental movement, the rise of sustainable development discourses, key global environmental summits in the 1990s, and rising levels of interest in the fisheries sector by the governments of both donor and recipient countries. Processes of ‘paradigm shifts’ were not swift or singular, rather they were affected by multiple, convergent factors over time. Our findings contribute to the literature on multi-lateral institutions as key actors in environmental governance shaping global development thinking, illustrating the arc of the last half-century of fisheries aid at the Bank while highlighting present dilemmas and future challenges that actors interested in working towards sustainable marine small-scale fisheries face.  相似文献

Sustainable fisheries management into the future will require both understanding of and adaptation to climate change. A risk management approach is appropriate due to uncertainty in climate projections and the responses of target species. Management strategy evaluation (MSE) can underpin and support effective risk management. Climate change impacts are likely to differ by species and spatially. We use a spatial MSE applied to a multi-species data-poor sea cucumber/béche-de-mer fishery to demonstrate the utility of MSE to test the performance of alternative harvest strategies in meeting fishery objectives; this includes the ability to manage through climate variability and change, and meeting management objectives pertaining to resource status and fishery economic performance. The impacts of fishing relative to the impacts of climate change are distinguished by comparing future projection distributions relative to equivalent no-fishing no-climate-change trials. The 8 modelled species exhibit different responses to environmental variability and have different economic value. Status quo management would result in half the species falling below target levels, moderate risks of overall and local depletion, and significant changes in species composition. The three simple strategies with no monitoring (spatial rotation, closed areas, multi-species composition) were all successful in reducing these risks, but with fairly substantial decreases in the average profit. Higher profits (for the same risk levels) could only be achieved with strategies that included monitoring and hence adaptive management. Spatial management approaches based on adaptive feedback performed best overall.  相似文献
