It has become increasingly clear that desertification can only be tackled through a multi-disciplinary approach that not only involves scientists but also stakeholders. In the DESIRE project such an approach was taken. As a first step, a conceptual framework was developed in which the factors and processes that may lead to land degradation and desertification were described. Many of these factors do not work independently, but can reinforce or weaken one another, and to illustrate these relationships sustainable management and policy feedback loops were included. This conceptual framework can be applied globally, but can also be made site-specific to take into account that each study site has a unique combination of bio-physical, socio-economic and political conditions. Once the conceptual framework was defined, a methodological framework was developed in which the methodological steps taken in the DESIRE approach were listed and their logic and sequence were explained. The last step was to develop a concrete working plan to put the project into action, involving stakeholders throughout the process. This series of steps, in full or in part, offers explicit guidance for other organizations or projects that aim to reduce land degradation and desertification. 相似文献

In India, as in many parts of the developing world, the dominant view has been that local people are causing natural resource degradation. New thinking in the natural resource management domain is gradually replacing the older views blaming local people for decline of natural resources. The new approach advocates decentralization of natural resource management. This is discussed in this paper in relation to the ongoing decentralization reforms in India. The centralized approach dominated natural resource management in India during the colonial period. The government after independence conveniently adopted the same approach, excluding local people from forests. Recent research and resistance from grassroot movements led to a paradigm shift towards decentralization at the policy level in natural resource management. It is not clear whether the new Joint Forest Management (JFM) policy in India is an attempt to institutionalize state dominance, or if it will lead to real decentralization. The data from several villages adjacent to the Sariska Tiger Reserve (STR), Rajasthan, India show that state dominance is still prevalent, despite constraints. The real challenge lies in providing flexibility within the JFM policy to adapt to local conditions in natural resource management. 相似文献

The local branches of the Russian Forestry Service, the leskhozy, were known for their efficiency and management skills in the Soviet era and were one of the very few community-based Soviet-type institutions to survive the transition. This article examines the role of the leskhozy in the new market economy. Our analysis is based on data from interviews with informants attached to the forestry sector in the Murmansk area. In some cases their knowledge of the leskhozy stretches back to the emergence of the system in 1947. Our principal finding is that the struggle to survive as a federal body in the current legal and economic climate is forcing the leskhozy to relegate sustainable forestry management, presumably their primary raison dêtre, to the lower portions of their list of priorities. Several consequences result. There is a heightened incidence of illegal logging, and corruption informs the allocation of forest areas to private interests. Stumpage prices have plummeted as timber from subsidized commercial cutting (ostensibly sanitary cutting or thinning) has flooded the markets. The root cause of these tribulations lies with the market-based harvesting permit system. Its introduction in the 1990s did little to eliminate the self-seeking practices of the old Soviet forestry management hierarchies. In the free market, local forestry managers can turn their dual responsibilities to their own advantage inasmuch as they control the allocation of harvesting permits while at the same time controlling logging practices. 相似文献

Sustaining Ecological Integrity with Respect to Climate Change: A Fuzzy Adaptive Management Approach 总被引:1,自引:0,他引:1
Tony Prato 《Environmental management》2010,45(6):1344-1351
A fuzzy adaptive management framework is proposed for evaluating the vulnerability of an ecosystem to losing ecological integrity
as a result of climate change in an historical period (ex post evaluation) and selecting the best compensatory management action for reducing potential adverse impacts of future climate
change on ecological integrity in a future period (ex ante evaluation). The ex post evaluation uses fuzzy logic to test hypotheses about the extent of past ecosystem vulnerability to losing ecological integrity
and the ex ante evaluation uses the fuzzy minimax regret criterion to determine the best compensatory management action for alleviating potential
adverse impacts of climate change on ecosystem vulnerability to losing ecological integrity in a future period. The framework
accounts for uncertainty regarding: (1) the relationship between ecosystem vulnerability to losing ecological integrity and
ecosystem resilience; (2) the relationship between ecosystem resilience and the extent to which observed indicators of ecological
integrity depart from their thresholds; (3) the extent of future climate change; and (4) the potential impacts of future climate
change on ecological integrity and ecosystem resilience. The adaptive management element of the framework involves using the
ex post and ex ante evaluations iteratively in consecutive time segments of the future time period to determine if and when it is beneficial
to adjust compensatory management actions to climate change. A constructed example is used to demonstrate the framework. 相似文献

Biodiversity action plans (BAPs), which are designed to protect and enhance wildlife, can also provide additional benefits to the local economy in terms of job creation and income generation. This paper considers the socio-economic benefits of implementing the BAP for species-rich hedges in Devon. It identifies employment and income generation for hedge contractors, farm labour, trainers, suppliers, processors of hedge products and the tourist industry as a result of 1 million expenditure on hedge restoration work to meet BAP targets. Using data from a survey of hedgerow contractors and key informants in related industries a multiplier analysis identified that funding for hedge restoration can have significant employment and income generation impacts on the local economy. In particular, this multiplier effect is enhanced because both hedge contractors and materials are largely sourced locally. 相似文献

Our recent paper advocating adaptive management of invasive nonnative species (INS) in Kings Bay, Florida received detailed
responses from both Daniel Simberloff, a prominent invasion biologist, and Mark Sagoff, a prominent critic of invasion biology.
Simberloff offers several significant lines of criticism that compel detailed rebuttals, and, as such, most of this reply
is dedicated to this purpose. Ultimately, we find it quite significant that Simberloff, despite his other stated objections
to our paper, apparently agrees with our argument that proposals for alternative management of established INS (i.e., alternatives
to minimization/eradication) should not be rejected on an a␣priori basis. We argue that more specific development and application
of adaptive approaches toward INS management, whether in Kings Bay or other appropriate case studies, would be facilitated
if ecosystem managers and invasion biologists follow Simberloff’s lead on this key point. While Sagoff largely shares (and,
indeed, served as a primary source for developing) our general arguments that challenge common moral and scientific assumptions
associated with invasion biology, he does question our suggestion that participatory adaptive management provides an appropriate
framework for approaching environmental problems in which science and politics are inherently entangled. We attempt to answer
this criticism through a brief sketch of what participatory adaptive management might look like for Kings Bay and how such
an approach would differ from past management approaches. 相似文献

Abstract: Adaptive management is often proposed as the most effective way to manage complex watersheds. However, our experience suggests that social and institutional factors constrain the search for, and integration of, the genuine learning that defines adaptive management. Drawing on our work as social scientists, and on a guided panel discussion at a recent AWRA conference, we suggest that watershed‐scale adaptive management must be recognized as a radical departure from established ways of managing natural resources if it is to achieve its promise. Successful implementation will require new ways of thinking about management, new organizational structures and new implementation processes and tools. Adaptive management encourages scrutiny of prevailing social and organizational norms and this is unlikely to occur without a change in the culture of natural resource management and research. Planners and managers require educational, administrative, and political support as they seek to understand and implement adaptive management. Learning and reflection must be valued and rewarded, and fora established where learning through adaptive management can be shared and explored. The creation of new institutions, including educational curricula, organizational policies and practices, and professional norms and beliefs, will require support from within bureaucracies and from politicians. For adaptive management to be effective researchers and managers alike must work together at the watershed‐scale to bridge the gaps between theory and practice, and between social and technical understandings of watersheds and the people who occupy and use them. 相似文献

Adaptive governance is advanced as a potent means of addressing institutional fit of natural resource systems with prevailing modes of political–administrative management. Its advocates also argue that it enhances participatory and learning opportunities for stakeholders over time. Yet an increasing number of studies demonstrate real difficulties in implementing adaptive governance ‘solutions’. This paper builds on these debates by examining the introduction of adaptive governance to water management in Chiang Mai province, north-west Thailand. The paper considers, first, the limitations of current water governance modes at the provincial scale, and the rationale for implementation of an adaptive approach. The new approach is then critically examined, with its initial performance and likely future success evaluated by (i) analysis of water stakeholders’ opinions of its first year of operation; and (ii) comparison of its governance attributes against recent empirical accounts of implementation difficulty and failure of adaptive governance of natural resource management more generally. The analysis confirms the potentially significant role that the new approach can play in brokering and resolving the underlying differences in stakeholder representation and knowledge construction at the heart of the prevailing water governance modes in north-west Thailand. 相似文献

Abstract: Information on the nature and relative contribution of different watershed sediment sources is recognized as a key requirement in the design and implementation of targeted management strategies for sediment control. A direct method of assessing sediment sources in a watershed that has attracted attention in recent years is sediment fingerprinting. The aim of this article is to describe the development of sediment fingerprinting as a research tool and to consider how the method might be transformed from a research tool to a management tool within a regulatory framework, with special reference to the United States total maximum daily load (TMDL) program. When compared with the current source assessment tools in developing sediment TMDLs, sediment fingerprinting offers considerable improvement as a tool for quantifying sources of sediment in terms of source type (e.g., channel vs. hillslope) as well as spatial location (subwatershed). While developing a conceptual framework for sediment TMDLs, we recognize sediment fingerprinting along with sediment budgeting and modeling as valuable tools in the TMDL process for developing justifiable sediment TMDLs. The discussions presented in this article may be considered as a first step toward streamlining the sediment fingerprinting approach for its wider application in a regulatory framework. 相似文献

Predicted increases in coral disease outbreaks associated with climate change have implications for coral reef ecosystems
and the people and industries that depend on them. It is critical that coral reef managers understand these implications and
have the ability to assess and reduce risk, detect and contain outbreaks, and monitor and minimise impacts. Here, we present
a coral disease response framework that has four core components: (1) an early warning system, (2) a tiered impact assessment
program, (3) scaled management actions and (4) a communication plan. The early warning system combines predictive tools that
monitor the risk of outbreaks of temperature-dependent coral diseases with in situ observations provided by a network of observers
who regularly report on coral health and reef state. Verified reports of an increase in disease prevalence trigger a tiered
response of more detailed impact assessment, targeted research and/or management actions. The response is scaled to the risk
posed by the outbreak, which is a function of the severity and spatial extent of the impacts. We review potential management
actions to mitigate coral disease impacts and facilitate recovery, considering emerging strategies unique to coral disease
and more established strategies to support reef resilience. We also describe approaches to communicating about coral disease
outbreaks that will address common misperceptions and raise awareness of the coral disease threat. By adopting this framework,
managers and researchers can establish a community of practice and can develop response plans for the management of coral
disease outbreaks based on local needs. The collaborations between managers and researchers we suggest will enable adaptive
management of disease impacts following evaluating the cost-effectiveness of emerging response actions and incrementally improving
our understanding of outbreak causation. 相似文献

Role of Adaptive Management for Watershed Councils 总被引:1,自引:0,他引:1
Habron G 《Environmental management》2003,31(1):0029-0041
Recent findings in the Umpqua River Basin in southwestern Oregon illustrate a tension in the rise of both community-based
and watershed-based approaches to aquatic resource management. While community-based institutions such as watershed councils
offer relief from the government control landowners dislike, community-based approaches impinge on landowners' strong belief
in independence and private property rights. Watershed councils do offer the local control landowners advocate; however, institutional
success hinges on watershed councils' ability to reduce bureaucracy, foster productive discussion and understanding among
stakeholders, and provide financial, technical, and coordination support. Yet, to accomplish these tasks current watershed
councils rely on the fiscal and technical capital of the very governmental entities that landowners distrust. Adaptive management
provides a basis for addressing the apparent tension by incorporating landowners' belief in environmental resilience and acceptance
of experimentation that rejects “one size fits all solutions.” Therefore community-based adaptive watershed management provides
watershed councils a framework that balances landowners' independence and fear of government intrusion, acknowledges the benefits
of community cooperation through watershed councils, and enables ecological assessment of landowner-preferred practices. Community-based
adaptive management integrates social and ecological suitability to achieve conservation outcomes by providing landowners
the flexibility to use a diverse set of conservation practices to achieve desired ecological outcomes, instead of imposing
regulations or specific practices. 相似文献

Why do some community-based natural resource management strategies perform better than others? Commons theorists have approached this question by developing institutional design principles to address collective choice situations, while other analysts have critiqued the underlying assumptions of community-based resource management. However, efforts to enhance community-based natural resource management performance also require an analysis of exogenous and endogenous variables that influence how social actors not only act collectively but do so in ways that respond to changing circumstances, foster learning, and build capacity for management adaptation. Drawing on examples from northern Canada and Southeast Asia, this article examines the relationship among adaptive capacity, community-based resource management performance, and the socio-institutional determinants of collective action, such as technical, financial, and legal constraints, and complex issues of politics, scale, knowledge, community and culture. An emphasis on adaptive capacity responds to a conceptual weakness in community-based natural resource management and highlights an emerging research and policy discourse that builds upon static design principles and the contested concepts in current management practice. 相似文献

We examined the principal effects of different information network topologies for local adaptive management of natural resources.
We used computerized agents with adaptive decision algorithms with the following three fundamental constraints: (1) Complete
understanding of the processes maintaining the natural resource can never be achieved, (2) agents can only learn by experimentation
and information sharing, and (3) memory is limited. The agents were given the task to manage a system that had two states:
one that provided high utility returns (desired) and one that provided low returns (undesired). In addition, the threshold
between the states was close to the optimal return of the desired state. We found that networks of low to moderate link densities
significantly increased the resilience of the utility returns. Networks of high link densities contributed to highly synchronized
behavior among the agents, which caused occasional large-scale ecological crises between periods of stable and high utility
returns. A constructed network involving a small set of experimenting agents was capable of combining high utility returns
with high resilience, conforming to theories underlying the concept of adaptive comanagement. We conclude that (1) the ability
to manage for resilience (i.e., to stay clear of the threshold leading to the undesired state as well as the ability to re-enter
the desired state following a collapse) resides in the network structure and (2) in a coupled social–ecological system, the
systemwide state transition occurs not because the ecological system flips into the undesired state, but because managers
lose their capacity to reorganize back to the desired state.

Our food and farming system is not socially, economically or ecologically sustainable. Many of the ills are a result of market competition driving specialization and linear production models, externalizing costs for environmental, social and cultural degradation. Some propose that market mechanisms should be used to correct this; improved consumer choice, internalization of costs and compensation to farmers for public goods. What we eat is determined by the path taken by our ancestors, by commercialization and fierce competition, fossil fuels and demographic development. Based on those, governments and the food industry are the choice architects who determine what we eat; consumer choice plays a marginal role. Using market mechanisms to internalize cost and compensate farmers for public goods has been proposed for decades but little progress has been made. There are also many practical, ethical and theoretical objections to such a system. The market is not a good master for a sustainable food system. Instead we need to find new ways of managing the food system based on food as a right and farming as a management system of the planet Earth. The solutions should be based on relocalization of food production and de-commodification of food and our symbionts, the plants and animals we eat. 相似文献

Ocean acidification has emerged over the last two decades as one of the largest threats to marine organisms and ecosystems. However, most research efforts on ocean acidification have so far neglected management and related policy issues to focus instead on understanding its ecological and biogeochemical implications. This shortfall is addressed here with a systematic, international and critical review of management and policy options. In particular, we investigate the assumption that fighting acidification is mainly, but not only, about reducing CO2 emissions, and explore the leeway that this emerging problem may open in old environmental issues. We review nine types of management responses, initially grouped under four categories: preventing ocean acidification; strengthening ecosystem resilience; adapting human activities; and repairing damages. Connecting and comparing options leads to classifying them, in a qualitative way, according to their potential and feasibility. While reducing CO2 emissions is confirmed as the key action that must be taken against acidification, some of the other options appear to have the potential to buy time, e.g. by relieving the pressure of other stressors, and help marine life face unavoidable acidification. Although the existing legal basis to take action shows few gaps, policy challenges are significant: tackling them will mean succeeding in various areas of environmental management where we failed to a large extent so far. 相似文献
