Nowadays, adaptation has become a key focus of the scientific and policy-making communities and is a major area of discussion in the multilateral climate change process. As climate change is projected to hit the poorest the hardest, it is especially important for developing countries to pay particular attention to the management of natural resources and agricultural activities. In most of these countries such as Cameroon, forest can play important role in achieving broader climate change adaptation goals. However, forest generally receives very little attention in national development programme and strategies such as policy dialogues on climate change and poverty reduction strategies. Using a qualitative approach to data collection through content analysis of relevant Cameroon policy documents, the integration of climate change adaptation was explored and the level of attention given to forests for adaptation analysed. Results indicate that, with the exception of the First National Communication to UNFCCC that focused mostly on mitigation and related issues, current policy documents in Cameroon are void of tangible reference to climate change, and hence failing in drawing the relevance of forest in sheltering populations from the many projected impacts of climate change. Policies related to forest rely on a generalized concept of sustainable forest management and do not identify the specific changes that need to be incorporated into management strategies and policies towards achieving adaptation. The strategies and recommendations made in those documents only serve to improve understanding of Cameroon natural resources and add resilience to the natural systems in coping with anthropogenic stresses. The paper draws attention to the need to address the constraints of lack of awareness and poor flow of information on the potentials of forests for climate change adaptation. It highlights the need for integrating forest for adaptation into national development programmes and strategies, and recommends a review of the existing environmental legislations and their implications on poverty reduction strategy and adaptation to climate change.  相似文献

The impacts of climate change, drought and desertification are closely interlinked, and most acutely experienced by populations whose livelihoods depend principally on natural resources. Given the increases in extreme weather events projected to affect the Southern Africa region, it is essential to assess how household and community-level adaptations have been helped or hindered by institutional structures and national policy instruments. In particular, there is a need to reflect on efforts related to the United Nations’ environmental conventions to ensure that policies support the maintenance of local adaptations and help retain the resilience of socio-economic and environmental systems. This paper examines three interlinked drivers of adaptation: climate change, desertification and drought, assessing the extent to which international and national policy supports local adaptive strategies in three countries in southern Africa. We show that while common ground exists between desertification and climate change adaptations at the policy level, they are insufficiently mainstreamed within broader development approaches. Similarly, there are some overlaps between policy-driven and autonomous local adaptations, but the mutually supportive links between them are poorly developed. Further efforts to integrate local adaptation strategies within policy could increase local resilience to environmental change, while also contributing to wider development goals.  相似文献

Diverging perspectives toward environmental problems, their causes, and solutions can exacerbate controversy in participatory decision making. Past research has examined the lay–expert divide in perceptions about diverse risks, but relatively few studies have examined multidimensional perspectives on water scarcity across expert groups with different knowledge systems. We address this gap by examining conflicting perspectives across ‘lay’ residents and academic and policymaking ‘experts’ in Phoenix, AZ. We analyze ecological concern about water issues, risk perceptions regarding the factors contributing to scarcity, and policy attitudes pertaining to resource management alternatives. All three groups expressed substantial concern for broad-scale water issues, especially drought. Residents exhibited a heightened tendency to blame other people for water scarcity, in addition to opposition toward stringent approaches such as water pricing. While strongly supporting the acquisition of more supplies, policymakers exhibited lower concern about regional water use rates while displacing blame away from anthropogenic causes compared to both residents and academic experts. Scientists, on the other hand, stressed the need for stricter regulation of water demand. Findings point to the challenges of meshing different knowledge systems for collaborative research and policy making.  相似文献

Coastal social ecological systems in eastern Africa are subject to a range of environmental, social and economic changes. They are already vulnerable to these multiple stressors, and the impacts of climate change are likely to further exacerbate their vulnerabilities. Some of these impacts may be observed and experienced already. The analysis presented in this paper is based on mixed methods empirical research exploring local perceptions of recent changes at four sites in coastal Tanzania and Mozambique. People recognise and rank a number of climate and non-climate stressors which have contributed towards more risky and less diverse livelihoods. Importantly, regional and international policy initiatives – in the form of river basin management in Mozambique and South Africa, and development of a Marine Protected Area in Tanzania – are perceived to further erode resilience and exacerbate vulnerabilities. We suggest this is a form of policy misfit, where policies developed to address a specific issue do not take account of cross-scale dynamics of change, the interactions between multiple stressors, nor longer term climate change. This policy misfit may be remedied by a move towards adaptive forms of governance, and necessitates an explicit focus on building the adaptive capacity of the poor and most vulnerable in society.  相似文献

Water is scarce in Mediterranean countries: cities are crowded with increasing demand; food is produced with large amounts of water; ecosystems demand more water that is often available; drought affects all. As climate change impacts become more noticeable and costlier, some current water management strategies will not be useful. According to the findings of CIRCE, the areas with limited water resources will increase in the coming decades with major consequences for the way we produce food and we protect ecosystems. Based on these projections this paper discusses water policy priorities for climate change adaptation in the Mediterranean. We first summarise the main challenges to water resources in Mediterranean countries and outline the risks and opportunities for water under climate change based on previous studies. Recognising the difficulty to go from precipitation to water policy, we then present a framework to evaluate water availability in response to natural and management conditions, with an example of application in the Ebro basin that exemplifies other Mediterranean areas. Then we evaluate adaptive capacity to understand the ability of Mediterranean countries to face, respond and recover from climate change impacts on water resources. Social and economic factors are key drivers of inequality in the adaptive capacity across the region. Based on the assessment of impacts and adaptive capacity we suggest thresholds for water policy to respond to climate change and link water scarcity indicators to relevant potential adaptation strategies. Our results suggest the need to further prioritise socially and economically sensitive policies.  相似文献

Climate is an important component of the operating environment for the Canadian mining sector. However, in recent years mines across Canada have been affected by significant climatic hazards, several which are regarded to be symptomatic of climate change. For the mining sector, climate change is a pressing environmental threat and a significant business risk. The extent to which the mining sector is able to mitigate its own impact and adapt to climate change will affect its long-term success and prosperity, and have profound economic consequences for host communities. This paper draws upon case studies conducted with mining operations in Canada involving in-depth interviews with mining professionals and analysis of secondary sources to characterize the vulnerability of the Canadian mining industry to climate change. Five key findings are discussed: i) mines in the case studies are affected by climate events that are indicative of climate change, with examples of negative impacts over the past decade; ii) most mine infrastructure has been designed assuming that the climate is not changing; iii) most industry stakeholders interviewed view climate change as a minor concern; iv) limited adaption planning for future climate change is underway; v) significant vulnerabilities exist in the post-operational phase of mines. This paper argues for greater collaboration among mining companies, regulators, scientists and other industry stakeholders to develop practical adaptation strategies that can be integrated into existing and new mine operations, including in the post-operational phase.  相似文献

The field of climate change is full of uncertainties that are limiting strategic disaster risk reduction planning. In this paper, however, we argued that there is lot to do before we get our hands on reliable estimates of future climate change impacts. It includes bringing together different stakeholders in a framework suggested in this paper, developing case studies that reflect long-term local impacts of climate change, capacity building of local stakeholders that enables them to take decisions under uncertainty etc. We proposed a simple scheme that brings together climate, disaster and policy community together to start a dialogue in a run-up to understanding wider aspects of long-term risk reduction at local level. Strategic thinking, which has only been restricted to national and regional planning to date, needs to be inculcated in local level disaster risk reduction and policy personnel as well. There is a need to move from the attitude of considering local level players as ‘implementers’ to ‘innovators’ for which developing a network of self learning and evolving organizations are required at the local level.  相似文献

Anthropogenic activities are responsible for the emission of gaseous and particulate pollutants that modify atmospheric composition. Such changes are, in turn, responsible for the degradation of air quality at the regional/local scale as well as for changes of climate. Air pollution and climate change are two intimately connected environmental issues. However, these two environmental challenges are still viewed as separate issues, which are dealt with by different science communities and within different policy frameworks. Indeed, many mitigation options offer the possibility to both improve air quality and mitigate climate change but, at the same time, mitigation options that may provide benefits to one aspect, are worsening the situation in the other. Therefore, coordinated actions taking into account the air quality-climate linkages are required. These actions need to be based on strong scientific grounds, as recognised by the European Commission that in the past few years has promoted consultation processes among the science community, the policy makers and the relevant stakeholders. Here, the main fields in which such coordinated actions are needed are examined from a policy perspective.  相似文献

An aggregated farm-level index, the Agri-environmental Footprint Index (AFI), based on multiple criteria methods and representing a harmonised approach to evaluation of EU agri-environmental schemes is described. The Index uses a common framework for the design and evaluation of policy that can be customised to locally relevant agri-environmental issues and circumstances. Evaluation can be strictly policy-focused, or broader and more holistic in that context-relevant assessment criteria that are not necessarily considered in the evaluated policy can nevertheless be incorporated. The Index structure is flexible, and can respond to diverse local needs. The process of Index construction is interactive, engaging farmers and other relevant stakeholders in a transparent decision-making process that can ensure acceptance of the outcome, help to forge an improved understanding of local agri-environmental priorities and potentially increase awareness of the critical role of farmers in environmental management. The structure of the AFI facilitates post-evaluation analysis of relative performance in different dimensions of the agri-environment, permitting identification of current strengths and weaknesses, and enabling future improvement in policy design. Quantification of the environmental impact of agriculture beyond the stated aims of policy using an ‘unweighted’ form of the AFI has potential as the basis of an ongoing system of environmental audit within a specified agricultural context.  相似文献

Atmospheric environmental policies have changed considerably over the last several decades. Clearly the relative importance of the various issues has changed over half a century, for example from smoke, sulphur dioxide and photochemical smog being the top priorities to greenhouse gases being the major priority.The traditional policy instrument to control emissions to the atmosphere has been command and control regulation. In many countries this was successful in reducing emissions from point sources, the first generation issues, and to a lesser extent, emissions from mobile and area sources, the second generation issues, although challenges remain in many jurisdictions. However once the simpler, easier, cheaper and obvious targets had been at least partially controlled this form of regulation became less effective. It has been complemented by other instruments including economic instruments, self-regulation, voluntarism and information instruments to address more complex issues including climate change, a third generation issue.Policy approaches to atmospheric environmental issues have become more complex. Policies that directly focus on atmospheric issues have been partially replaced by more integrated approaches that consider multimedia (water, land, etc.) and sustainability issues.Pressures from stakeholders for inclusion, greater transparency and better communication have grown and non-government stakeholders have become increasingly important participants in governance.The scale of the issues has evolved from a local to national, regional and global scales. Consequently the approaches to atmospheric environmental policy have also been amended. The international dimensions of atmospheric issues have grown in prominence and challenge governance and politics with pressures for international cooperation and harmonisation of policies. This is reducing the policy flexibility of national governments.Partially in response to these changes, to manage environmental risks and protect their brands, leaders in the corporate sector have generally found it beneficial to increase responsibility and accountability, including establishing corporate environmental policies, environmental management systems, risk management, sustainability reporting and other measures.This analysis clearly identifies that these changes are inter-related. Acting together they have transformed the way that atmospheric issues are governed in the last several decades in developed countries. Together they have led to governments in many developed countries vacating leadership roles and becoming increasingly managers of the policy process. As the leadership role of governments has been partially eroded, governments are more reliant on persuasion and diplomacy in their relations with stakeholders. As a consequence, governance arrangements have become more complex, multilevel and polycentric.  相似文献

Water management in Uzbekistan (Central Asia) is facing tremendous challenges. They are rooted in past and present environmental degradation, the socio-economic transition after the breakup of the Soviet Union, and the impacts of climate change. The Uzbek government has initiated reforms in the agricultural and water sectors to steer the socio-economic transition and address the threats of increasing water scarcity and decreasing agricultural productivity. However, despite the urgency of the problems and massive international assistance changes to the water management regime have only been minimal so far. In this paper we identify major structural barriers for adaptation of the water management regime through an analysis of two recent policy processes. Both processes address pressing water management issues such as “coping with extreme events” and “providing water for ecosystems”. They were analyzed using the Management and Transition Framework as well as a group model building exercises with stakeholders on the national, regional and local levels. The analyses reveal a lack of vertical integration across administrative levels of the formal system and a still prevailing strong centralization of water management. Moreover the water management regime is strongly influenced by informal institutions that shape the outcomes of policy processes. The interactions guided by informal institutions provide an informal link between different administrative levels of the regime. However, those informal networks and the social capital embedded in them rather prevent needed changes. The resulting combination of top down institutional change initiated by socio-economic transition and bottom-up consolidation of the existing status quo via informal processes and networks prevents social learning. It also slows down an adaptation process that potentially could lead to a transition towards a more adaptive regime.  相似文献

The need to understand and mitigate diffuse water pollution from agriculture (DWPA) using a range of monitoring or modelling techniques and abatement methods has never been greater. In response to the widely reported detrimental environmental impacts of such pollution and the desire to safeguard water resources, a number of important legislative drivers have been introduced, including the Water Framework Directive (WFD) for EU member states. Efforts to commission research and introduce policy options that address the key requirements of over-arching legislation, increasingly point to a number of common and important issues for policy makers. Whereas our understanding of, and ability to predict, pollutant loadings is reasonably well developed, coupling such pressures to ecological impacts remains a difficult task due to the limited functionality of available toolkits. It is important for mitigation programmes to consider multiple pollutants especially given the risks of pollution swapping and to support the uptake of abatement options that are economically and socially acceptable to the stakeholders involved. Appropriate spatial targeting of mitigation methods will continue to come under scrutiny, especially in the context of additional environmental pressures like climate change. Given its key role in governing the transfer and fate of priority nutrients and contaminants and its well-documented negative habitat impacts, sediment must be given a higher profile in diffuse pollution policy. The latter does, however, require further investigation of background sediment loads necessary for healthy habitats and associated sediment standards or thresholds, in order that catchment compliance can be more reliably assessed. Delayed water quality response to the mitigation of DWPA must be assessed and understood, as a means of informing stakeholders and policy options. A further challenge is posed by the need to place DWPA in the context of pollution from alternative sectors so that a more holistic approach to understanding and managing pressures and impacts and engaging stakeholders can be encouraged.  相似文献

This paper summarizes the results of a primarily qualitative (with certain quantitative elements) socio-ecological study on three Greek islands of the Aegean Archipelago to characterize fire science and policy at regional and local levels, and perceptions of fire risk. Among the most important factors influencing dynamics of fire regimes on the islands are changing land use patterns and practices, and changes in climate and fuel conditions. While use of scientific information is not widespread, there are individuals in all three islands who regularly consult scientific sources. Although fire policy is largely controlled at the national and European Union levels, local activity also occurs, most notably through the volunteer fire fighting organizations, interactions with local officials, and public education efforts. However, though seen as important, significant lack of financial support and resources exist to support prevention and pre-suppression programs. Prevention of fires on the islands, including the use of prescribed burning, is relatively inadequate, and while an intense interest in preventing the loss of communities and ecosystems is frequently encountered, public participation in fire prevention remains limited. The findings suggest that relying on local knowledge, in combination with fire managers’ decision-making abilities, could improve fire management options and reduce wildfire suppression costs and ecological disasters.  相似文献

The Social Amplification of Risk Framework (SARF) is often used as a conceptual tool for studying diverse risk perceptions associated with environmental hazards. While widely applied, it has been criticised for implying that it is possible to define a benchmark ‘real’ risk that is determined by experts and around which public risk perceptions can subsequently become amplified. It has been argued that this objectification of risk is particularly problematic when there are high levels of scientific uncertainty and a lack of expert consensus about the nature of a risk and its impacts. In order to explore this further, this paper examines how ‘experts’ – defined in this case as scientists, policy makers, outbreak managers and key stakeholders – construct and assemble their understanding of the risks associated with two invasive tree pest and disease outbreaks in the UK, ash dieback and oak processionary moth. Through semi-structured interviews with experts in each of the case study outbreaks, the paper aims to better understand the nature of information sources drawn on to construct perceptions of tree health risks, especially when uncertainty is prevalent. A key conclusion is that risk assessment is a socially-mediated, relational and incremental process with experts drawing on a range of official, anecdotal and experiential sources of information, as well as reference to past events in order to assemble the risk case. Aligned with this, experts make attributions about public concern, especially when the evidence base is incomplete and there is a need to justify policy and management actions and safeguard reputation.  相似文献

The Mediterranean and neighboring countries are already experiencing a broad range of natural and man-made threats to water security. According to climate projections, the region is at risk due to its pronounced susceptibility to changes in the hydrological budget and extremes. Such changes are expected to have strong impacts on the management of water resources and on key strategic sectors of regional economies. Related developments have an increased capacity to exacerbate tensions, and even intra- and inter-state conflict among social, political, ecological and economic actors. Thus, effective adaptation and prevention policy measures call for multi-disciplinary analysis and action.This review paper presents the current state-of-the-art on research related to climate change impacts upon water resources and security from an ecological, economic and social angle. It provides perspectives for current and upcoming research needs and describes the challenges and potential of integrating and clustering multi-disciplinary research interests in complex and interwoven human-environment systems and its contribution to the upcoming 5th assessment report of the IPCC.  相似文献

Biological invasions are a significant component of human-caused global change and is widely regarded as one of the main threats to natural biodiversity. Isolated anthropogenic water bodies created in the areas that are deprived of natural freshwater habitats allow the survival and reproduction of alien species on newly settled sites. They are often small with water level fluctuations causing frequent environmental disturbances. The colonisation success may be the result of the rate of their degradation. The aims of the study were to determine the environmental conditions that affect the existence of alien species of gastropods in this type of aquatic environment and to examine whether the occurrence of non-native species affects the community structure of the native species. This study made it possible to group woodland ponds according to the occurrence of the three invasive species in snail communities and discuss the environmental conditions present in these pond types. Analysis of water properties emphasised the distinctiveness of the selected pond types. In ponds of the Potamopyrgus antipodarum type, we found the highest values of some parameters mainly hardness, conductivity, and content of calcium and chlorides, in contrast with the Physella acuta type, which were characterised by the lowest values except for phosphates and nitrites. In the Ferrissia fragilis type, we found the highest nitrate content. Data on the occurrence of alien species in different water environments play an important role in actions which are taken to prevent new invasions and spread of non-native species as well as to reduce future impacts of invaders.  相似文献

Article 4.1(F) of the Framework Convention on Climate Change commits all parties to take climate change considerations into account, to the extent feasible, in relevant social, economic and environmental policies and actions and to employ methods such as impact assessments to minimize adverse effects of climate change. This could be achieved by,inter alia, incorporating climate change risk assessment into development planning processes i.e. relating climatic change to issues of habitability and sustainability. Adaptation is an ubiquitous and beneficial natural and human strategy. Future adaptation (or, better, adjustment) to climate is inevitable at the least to decrease the vulnerability to current climatic impacts. The urgent issue is the mismatch between the predictions ofglobal climatic change and the need for information onlocal to regional change in order to develop adaptation strategies. Mitigation efforts are essential since the more successful mitigation activities are, the less need there will be for adaptation responses. Moreover, mitigation responses can be global (e.g. a uniform percentage reduction in greenhouse gas emissions) while adaptation responses will be local to regional in character and therefore depend upon confident predictions of regional climatic change. The dilemma facing policymakers is that scientists have considerable confidence in likely global climatic changes but virtually zero confidence in regional changes. Mitigation and adaptation strategies relevant to climatic change can most usefully be developed in the context of sound understanding of climate, especially the near-surface continental climate, permitting discussion of societally relevant issues. Unfortunately, climate models cannot yet deliver this type of regionally and locationally specific prediction and some aspects of current research even seem to indicate increased uncertainty. These topics are explored in this paper using the specific example of the prediction of land-surface climate changes.  相似文献

While several empirical and theoretical studies have clearly shown the negative effects of climate or landscape changes on population and species survival only few of them addressed combined and correlated consequences of these key environmental drivers. This also includes positive landscape changes such as active habitat management and restoration to buffer the negative effects of deteriorating climatic conditions. In this study, we apply a conceptual spatial modelling approach based on functional types to explore the effects of both positive and negative correlations between changes in habitat and climate conditions on the survival of spatially structured populations. We test the effect of different climate and landscape change scenarios on four different functional types that represent a broad spectrum of species characterised by their landscape level carrying capacity, the local population turnover rates at the patch level (K-strategies vs. r-strategies) and dispersal characterstics. As expected, simulation results show that correlated landscape and climatic changes can accelerate (in case of habitat loss or degradation) or slow down (in case of habitat gain or improvement) regional species extinction. However, the strength of the combined changes depends on local turnover at the patch level, the overall landscape capacity of the species, and its specific dispersal characteristics. Under all scenarios of correlated changes in habitat and climate conditions we found the highest sensitivity for functional types representing species with a low landscape capacity but a high population growth rate and a strong density regulation causing a high turnover at the local patch level.The relative importance of habitat loss or habitat degradation, in combination with climate deterioration, differed among the functional types. However, an increase in regional capacity revealed a similar response pattern: For all types, habitat improvement led to higher survival times than habitat gain, i.e. the establishment of new habitat patches. This suggests that improving local habitat quality at a regional scale is a more promising conservation strategy under climate change than implementing new habitat patches. This conceptual modelling study provides a general framework to better understand and support the management of populations prone to complex environmental changes.  相似文献

Research was conducted to identify some of the current pollution minimisation practices adopted in Australia's mining and mineral processing industries. Initially, 84 mining and mineral processing companies were approached for inclusion in the study, with request only made for information that was available to the company stakeholders and the wider general community. Among the responses received, BHP Billiton, BlueScope Steel, Newmont Australia Limited and AngloGold Australia provided the information requested and/or a substantial quantity of information through reports on their company website. Analysis of the data collected for these companies indicated that improvements were made, and that policies had been implemented over the previous few years. The pollution minimisation and policy practices adopted at the operations of these companies include environmental management systems, advanced pollution control technologies, environmental awareness training for employees, and requirement – from company stakeholders – for increased accountability of environmental impacts.  相似文献

In recent decades, the growing need for biodiversity conservation and the different means of achieving it have been defined in international and national procedures regulated by governments and parliaments on the one hand, and in governance processes run by different stakeholders on the other. In local contexts, however, people perceive the abstract phenomenon of biodiversity conservation through the environment in which they live and through their social and cultural positions. We examine Finnish forest owners’ experiences and perceptions of biodiversity conservation, and consider the compatibility of these perceptions with national conservation policy. Our work is based on a survey of forest owners and the content analysis of national policy documents. We found that the perceptions of forest owners and the documents of nature conservation policy had elements that both overlapped and contradicted each other, thus reflecting different interpretations of forest ownership and biodiversity conservation. Moreover, the national Forest Biodiversity Program – an outcome of a multilateral governance process – was more successful in combining conservation policy with various perspectives of forest owners than was the authoritatively formulated Nature Conservation Act and Decree. This result indicates that governance processes can address conflicts of interest in the use of natural resources.  相似文献
