Governance across the land-sea interface is an emerging challenge. The propensity for, and intensity of social-ecological interactions across this interface (e.g., eutrophication, sedimentation) are being exacerbated by cross-system threats (e.g., climate change). We draw on a systematic review of 151 peer-reviewed papers on governance and land-sea connections to (1) outline the current state of the literature, (2) examine the predominance of different approaches to address land-sea interactions, (3) characterize how governance is conceptualized within these approaches, (4) investigate governance challenges, and (5) provide insights into effective governance. The review finds that the number of relevant papers published per year has generally been increasing, and most of these papers are found in interdisciplinary journals. Ecosystem-based management is the most predominant approach found in the literature as a means to address land-sea interactions. Papers referring to ecosystem-based management are more likely than those referring to alternative management approaches (e.g., integrated management) to highlight science-policy integration and the need to account for interactions between ecosystem components as elements of effective governance. The main governance challenges include determining boundaries, addressing cross-scale effects, and accessing knowledge. However, few empirical studies of governance across the land-sea interface have been completed. A richer conceptual framework of governance is required to improve our ability to navigate the rapid social and environmental change occurring across the land-sea interface.  相似文献

This paper evaluates how geographical theories of scale can give a more robust understanding of the governance of complex environmental risks. We assess the case of fisheries in Iwaki City, Fukushima Prefecture in Japan following the 2011 nuclear disaster. Fisheries in Iwaki and Fukushima more widely are operating on a trial basis as understanding of the marine radiation situation becomes clearer, however questions remain over whether consumers will buy produce and to what extent full-scale fisheries will resume. Based on empirical fieldwork undertaken in Fukushima plus supporting documentary analysis, we construct a scalar account of post-disaster Iwaki fisheries. We use this to argue that framing post-disaster fisheries governance at the municipal scale rather than the prefectural scale has opened up opportunities for enacting the more two-way forms of risk governance that contemporary environmental issues may require. We also argue locally-situated ‘experts’ (e.g. fisheries extension officers and citizen science groups) play a key role in negotiating citizens’ and fishers’ relationships with larger-scale scientific discourses due to their ability to work across scales, despite having less techno-scientific expertise than their national-level counterparts. In turn, we suggest that in governance of complex environmental issues, policymakers ought to (a) consider how community-level expectations may differ from risk governance processes developed at larger scales; (b) identify key institutions or figures who can work across scales and support them accordingly; and (c) show cognisance to the social effects that may arise from spatial demarcation of environmental problems.  相似文献

Increasingly, Native American and non-Native governments, institutions and individuals are searching for cooperative ways to address environmental problems. While such approaches can offer substantial benefits over top-down or unilateral efforts, there are also potential pitfalls, especially when considering the needs and interests of the Native parties. Among these are threats to their status as sovereign nations, and to their political, economic and cultural autonomy. Given such concerns, many Indian Nations are seeking models for collaboration which protect their unique status based on indigenous and treaty rights, while respecting their cultural identity, values, and indigenous knowledge. In this paper we explore how one Native group in particular, a coalition of Haudenosaunee Nations in the US and Canada, has dealt with these complex issues. We show how positive relationships with outside agencies and researchers have been made possible through the use of mechanisms and processes based on traditional Haudenosaunee concepts and values. Finally, we explore how one item in particular, a 17th century treaty belt called the Kaswentha, offers a powerful symbol for forming relationships which respect Haudenosaunee autonomy while allowing collaborative partnerships to address critical environmental concerns.  相似文献

2016 marked the 25th anniversary of the Protocol on Environmental Protection to the Antarctic Treaty. Terrestrial ice-free areas constitute approximately 0.18% of Antarctica, but represent the most biologically active, historically rich, and environmentally sensitive sites. Antarctic soils are easily disturbed and environmental legacies of human activities are scattered across the continent; many are remnants of the 1950s-1980s when environmental protection was less comprehensive than today. Adoption of the Environmental Protocol in 1991 represented an important and proactive shift in Antarctic governance, securing environmental protection as a fundamental tenet of the Treaty System. Twenty five years on standards of environmental management have greatly improved, yet environmental pressures are compounding. Shortcomings in the implementation of the Environmental Protocol exist due to disparities in cultural values, operational realities, and inconsistent environmental impact assessments among governments and National Antarctic Programs. Non-native species management remains underdeveloped; and there is inadequate representation of all biogeographic regions within the Protected Area system; therefore jeopardizing conservation of Antarctic biodiversity and the integrity of the soil environment. Fundamental improvements are required to address the current shortcomings and ensure effective environmental protection for the next 25 years, including: (1) increased multinational and multidisciplinary collaboration to answer targeted research questions addressing contemporary management challenges, (2) effective communication of science to policy makers and environmental managers to inform decision- making, and (3) making the mandate of long-term monitoring of the terrestrial environment a high priority for all governments signatory to the Antarctic Treaty.  相似文献

Management of common-pool natural resources is commonly implemented under institutional models promoting devolved decision-making, such as co-management and community-based management. Although participation of local people is critical to the success of devolved commons management, few studies have empirically investigated how individuals’ participation is related to socioeconomic factors that operate at multiple scales. Here, we evaluated how individual- and community-scale factors were related to levels of individual participation in management of community-based marine protected areas in Indonesia. In addressing this aim, we drew on multiple bodies of literature on human behaviour from economics and social science, including the social-ecological systems framework from the literature on common-pool resources, the theory of planned behaviour from social psychology, and public goods games from behavioural economics. We found three key factors related to level of participation of local people: subjective norms, structural elements of social capital, and nested institutions. There was also suggestive evidence that participation was related to people’s cooperative behavioural disposition, which we elicited using a public goods game. These results point to the importance of considering socioeconomic factors that operate at multiple scales when examining individual behaviour. Further, our study highlights the need to consider multiscale mechanisms other than those designed to appeal to self-interested concerns, such as regulations and material incentives, which are typically employed in devolved commons management to encourage participation. Increased understanding of the factors related to participation could facilitate better targeting of investments aimed at encouraging cooperative management.  相似文献

Flash flood forecasting, warning and risk management: the HYDRATE project   总被引:6,自引:0,他引:6  
The management of flash flood hazards and risks is a critical component of public safety and quality of life. Flash-floods develop at space and time scales that conventional observation systems are not able to monitor for rainfall and river discharge. Consequently, the atmospheric and hydrological generating mechanisms of flash-floods are poorly understood, leading to highly uncertain forecasts of these events. The objective of the HYDRATE project has been to improve the scientific basis of flash flood forecasting by advancing and harmonising a European-wide innovative flash flood observation strategy and developing a coherent set of technologies and tools for effective early warning systems. To this end, the project included actions on the organization of the existing flash flood data patrimony across Europe. The final aim of HYDRATE was to enhance the capability of flash flood forecasting in ungauged basins by exploiting the extended availability of flash flood data and the improved process understanding. This paper provides a review of the work conducted in HYDRATE with a special emphasis on how this body of research can contribute to guide the policy-life cycle concerning flash flood risk management.  相似文献

Using a human security perspective, we investigate how the history of land tenure changes has driven sustainability in southern African savannas. The paper examines four countries—Botswana, Mozambique, South Africa and Zimbabwe. Two research questions are addressed: first, how has colonial land tenure and distribution affected people's options and capacity to end, mitigate or adapt to risks to their human, environmental and social rights, and what have been the related effects on land uses and degradation? Second, to what extent have post-independence land reforms addressed threats to human security and political causes of land degradation? The inequitable distribution of land and colonial legacy of dual or pluralistic systems of tenure are found to be at the root of many agrarian and environmental problems. Post-independence land reforms have largely failed to address these fundamental issues, sometimes even reinforcing threats to social, economic and environmental sustainability. The skewed distribution of land and resources, insecure rights, and the marginalisation and restriction of savanna livelihood systems have persisted, undermining human security and environmental integrity in the region as well as leading to mounting conflict and insecurity.  相似文献

Both for its technological and institutional innovations and for its history of conflicts, California's water system has been one of the most observed in the world. This article and this Special Issue on the CALFED Bay-Delta Program continue in this tradition. CALFED is likely the most ambitious experiment in collaborative environmental policy and adaptive management the world has seen to date. This Issue moves beyond the celebratory tone of other analyses of collaborative, adaptive management and looks closer into how collaborative networks work to produce innovation, and more importantly to reflect also on their inherent contradictions, limitations and “dark sides”. While collaborative governance enhances mutual understandings and can be a source of innovation, it appears ill-suited to resolve alone the distributive dilemmas at the core of many water – and other environmental – conflicts. A lacuna in existing research concerns the institutional design of effective boundaries and linkages between democratic politics, legitimate authority, and adaptive governance, i.e. the mix of institutions that can provide sufficient responsibility, accountability and democratic legitimacy, without choking off the self-organizing interaction, shared learning, and communication that is at the heart of collaboration. A painful realization in the Delta is that environmental conservation and further growth may be fundamentally at odds; efficient win–win solutions, institutional or technological, seem insufficient to satisfy the competing demands posed upon the system. Radical decisions and changes might be necessary, but they seem unlikely under current institutional arrangements and political conditions.  相似文献

Most research linking global environmental change and food security focuses solely on agriculture: either the impact of climate change on agricultural production, or the impact of agriculture on the environment, e.g. on land use, greenhouse gas emissions, pollution and/or biodiversity. Important though food production is, many other factors also need to be considered to understand food security. A recent international conference on “Environmental Change and Food Security: Bridging Science, Policy and Development for Adaptation” included a range of papers that embraced the multiple dimensions of the food systems that underpin food security. The major conclusion from the conference was that technical fixes alone will not solve the food security challenge. Adapting to the additional threats to food security arising from major environmental changes requires an integrated food system approach, not just a focus on agricultural practices. Six key issues emerged for future research: (i) adapting food systems to global environmental change requires more than just technological solutions to increase agricultural yields; (ii) tradeoffs across multiple scales among food system outcomes are a pervasive feature of globalized food systems; (iii) within food systems, there are some key underexplored areas that are both sensitive to environmental change but also crucial to understanding its implications for food security and adaptation strategies; (iv) scenarios specifically designed to investigate the wider issues that underpin food security and the environmental consequences of different adaptation options are lacking; (v) price variability and volatility often threaten food security; and (vi) more attention needs to be paid to the governance of food systems.  相似文献

Much has been said about the need and benefits of consensus building for resolving disagreements about water and environmental management. Less has been said about how to better convene and facilitate those processes. This paper focuses on the latter, examining the challenges and breakthroughs encountered when decision-makers convene consensus building processes that seek an agreement among stakeholders who believe they have “apparently irreconcilable differences.” The research described here analyzes two multi-stakeholder, collaborative processes convened by the CALFED Bay-Delta Program (CALFED) on the issue of agricultural water use efficiency in the Sacramento and San Joaquin river watersheds of California. The first process made very little progress; however, stakeholder representatives in the second were able to forge an agreement that included significant innovation and surprising risk taking by all sides. Analyzing the two processes, this paper shows that the stakeholders, conveners, and facilitators in these processes had to do much more than make the discrete trades across interests envisioned in consensus building theory or reframing as described in theories about conflict and frames. Looking at the data, this paper shows how several concepts from outside consensus building—including boundary objects and interlanguage—along with less well-known concepts and issues within the consensus building literature—bricolage and representation—can provide insights into how the Steering Committee accomplished what it did. This paper introduces these additional concepts, how they mattered in this CALFED process, and suggests a complex set of interrelated insights into how future collaborative and integrative environmental programs can approach the most difficult environmental policy and management conflicts.  相似文献

论文根据对甘肃省土地沙化区农民的调查数据,运用Logit模型,基于环境公平的视角探讨土地沙化区农民特征与其感知的环境灾害风险的关系。从个体特征上讲,受访者性别和婚姻状况与其感知的环境灾害风险之间的相关关系不显著,受访者受教育程度与其感知的环境灾害风险之间呈显著正相关关系;从经济特征上讲,农民所感知的环境灾害风险主要体现在土地经营收入的损失上,且感知的环境灾害风险与其家庭年总收入之间的关系呈现倒“U”型趋势;从生态环境特征上讲,环境的治理和改善有利于降低农民感知的环境灾害风险。通过分析认为农民所承受的环境灾害风险的不公平一定程度上是农民在社会经济领域所受到的不公平的体现,农民对环境不公平的感知在家庭年总收入10万元左右时最明显,环境不公平主要体现在环境灾害风险对土地经营收入的影响上。农民对生态环境治理效果的认知与对环境公平的感知具有一致性。  相似文献

Traditional flood protection methods have focused efforts on different measures to keep water out of floodplains. However, the European Flood Directive challenges this paradigm (Hartmann and Driessen, 2013). Accordingly, flood risk management plans should incorporate measures brought about by collaboration with local governments to develop and implement these measures (Johann and Leismann, 2014). One of the challenges of these plans is getting and keeping stakeholders involved in the processes related to flood risk management. This research shows that that this challenge revolves around how flood risks are socially constructed.Therefore it is essential to understand and explain the risk perception of stakeholders. System Theory by Luhmann provides the analytical distinction between ‘internal risk’ and ‘external danger’ as key concepts to understand whether or not stakeholders will take action (Luhmann, 1993). While perceptions of ‘external danger’ will not lead to action, perceptions of ‘internal risk’ urge stakeholders to take action.The cases of the rivers Lippe and Emscher in the dense populated region between Duisburg and Dortmund in Germany illustrate how these theoretical concepts materialise in practice. This contribution shows how flood risks are socially constructed and how this construction is influenced by the European flood risk management plan. While clearing up some of the difficulties from the Flood Directive, the research shows a gap between the Flood Directive and the current theory and planning practice, which needs to be addressed in further research.  相似文献

As one of the most well-documented biogeographic patterns, the distance-decay relationship provides insights into the underlying mechanisms driving biodiversity distribution. Although wastewater treatment plants (WWTPs) are well-controlled engineered ecosystems, this pattern has been seen among microbial communities in activated sludge (AS). However, little is known about the relative importance of environmental heterogeneity and dispersal limitation in shaping AS microbial community across China; especially they are related to spatial scale and organism types. Here, we assessed the distance-decay relationship based on different spatial scales and microbial phylogenetic groups by analyzing 132 activated sludge (AS) samples across China comprising 3,379,200 16S rRNA sequences. Our results indicated that the drivers of distance-decay pattern in China were scale-dependent. Microbial biogeographic patterns in WWTPs were mainly driven by dispersal limitation at both local and national scales. In contrast, conductivity, SRT, and pH played dominant roles in shaping AS microbial community compositions at the regional scale. Turnover rates and the drivers of beta-diversity also varied with microorganism populations. Moreover, a quantitative relationship between dispersal limitation ratio and AS microbial turnover rate was generated. Collectively, these results highlighted the importance of considering multiple spatial scales and micro-organism types for understanding microbial biogeography in WWTPs and provided new insights into predicting variations in AS community structure in response to environmental disturbance.  相似文献

Climate change poses a serious threat to sea turtles (Cheloniidae) as their terrestrial reproductive phase is only successful within a limited range of environmental and physical conditions. These conditions are likely to become less optimal as climate change progresses. To date, management and conservation of sea turtles has focused almost entirely on non-climatic stressors, due at least in part to practitioners not knowing what strategies to take and the feasibility and risks of potential strategies. To aid the management of sea turtles in a changing environment, we identified management strategies via a focus workshop and surveys to mitigate the impacts of climate change to the terrestrial reproductive phase of sea turtles. The effectiveness, ecological risks and potential social and logistical constraints associated with implementing each of the identified management strategies is discussed. Twenty management strategies were identified; strategies varied from habitat protection to more active and direct manipulation of nests and the nesting environment. Based on our results, we suggest a three-pronged approach to sea turtle conservation in light of climate change, where managers and researchers should: 1) enhance sea turtle resilience to climate change by mitigating other threats; 2) prioritise implementing the ‘no regret’ and ‘reversible’ management strategies identified here; and 3) fill the knowledge gaps identified to aid the trial and implementation of the potential strategies identified here. By combining these three approaches our collective toolkit of sea turtle management strategies will expand, giving us an array of viable approaches to implement as climate change impacts become more extreme.  相似文献

Ecology may benefit from long term, large scale experiments on low intensity farming to test theoretical principles and convert them into practical lessons. One century of land conversion in the Argentine pampas, and its effect on critical ecological properties, were analysed and discussed. Land transformation has resulted in significant changes of land use, land cover, energy flow, nutrient dynamics, hydrology, and the trade-offs between productivity, stability and sustainability. The analytical procedure involved the complementary utilisation of different data sources and approaches. The study was focused on large geographical scales: the entire pampas and its five ecoregions. Results were interpreted under the theoretical framework of succession in ecology. The historical conversion of natural grasslands into cultivated grasslands and croplands was not homogeneous, determining a variety of land use and land cover patterns. Due to its higher productivity, much more energy, nutrients and water were mobilised in the rolling pampas than in the other ecoregions. This study provides lessons about how the energy flow, the nutrient dynamics and the hydrological process are modified by land transformation under low external-input conditions. Technical coefficients to be applied in emerging fields of environment administration such as ecological-monitoring, environmental accounting and auditing, agro-ecological certification, land evaluation and allocation, and land management, can also be supplied by this kind of studies.  相似文献

New York City’s extensive municipal park system is home to forests, wetlands, and grasslands that provide important ecological and social benefits to the city’s population. While efforts and programs exist to restore and protect these spaces, management recommendations are complex due to variable conditions in urban natural areas. To advance the management of urban natural areas, the first comprehensive ecological assessment was conducted through a collaborative effort across 4000 ha of natural areas within New York City parkland. Field and spatial data were collected and analyzed to identify the extent of forests, the types of forests, and their conditions. This approach will help guide decision-making and prioritization of natural area management at the regional level by developing unique quantitative targets for urban forests. This project serves as an example of collaboration between private and public institutions advancing the governance of urban natural areas to achieve citywide conservation and policy goals.  相似文献
