Climate change is likely to present new and substantially unpredictable challenges to human societies. The prospect is of
particular concern at the local and regional levels, since vulnerability and adaptive capacity are location-specific and many
decisions regarding climate-induced risks are made at those levels. In this light, one is compelled to survey stakeholders’
understandings of their situation and perceived problems. Assessments should also include the context of other ongoing changes,
such as globalisation, that will impact communities and exacerbate their vulnerabilities. This paper presents an assessment
of vulnerability and adaptive capacity in the forestry sector in the Pite River basin in northern Sweden. The study was carried
out using a multi-method design encompassing literature surveys, interviews with stakeholders, and stakeholder meetings. The
paper concludes that while climate change will have an impact on the region, its effect will be superseded by that of broader
socio-economic changes. The results illustrate the need to understand local and regional perceptions of adaptation in formulating
appropriate policy measures. 相似文献

An intensive approach to Barrow, Alaska’s adaptations to climate change and variability during recent decades suggests reconsideration
of the interconnected roles of science, policy, and decision-making structures. First, profound uncertainties are inherent
in unique interactions among the many natural and human factors affecting Barrow’s vulnerability. Science cannot significantly
reduce these uncertainties through extensive approaches, but intensive approaches can reconstruct and update local trends,
clarify the underlying dynamics, and harvest experience for policy purposes. Second, sound policies to reduce Barrow’s vulnerability
to coastal erosion and flooding must incorporate these profound uncertainties and the multiple values of the community. Minimizing
vulnerability to climate change is only one of the community’s interests, and must compete with other interests for limited
time, attention, funds and other resources. Third, the community itself is in the best position to understand its own context,
to decide on sound policies, and to take responsibility for those decisions. In short, local context matters in science, policy,
and decision-making structures for adaptation to climate change and variability. Overall, cognitive constraints may be the
most important human dimension of climate change. Factoring the global problem into more tractable local problems would make
the most of our cognitive capacity. 相似文献

Discerning the general public’s support of climate change policies is a significant part of understanding the political and
social dynamics of mitigating climate change. National level surveys are a useful tool for furthering this understanding but
present multiple challenges, two of which are addressed in this paper. The first challenge is that the U.S. public’s limited
knowledge of climate change issues requires that information is provided in the survey, and that the content of this information
is thought to be critical in eliciting accurate responses. Second, the use of national surveys may mask regional and state
differences that result from the distribution of predicted climate change impacts and varying social contexts. We explore
these issues by assessing the impacts of (a) the provision of information on climate change impacts at different scales (national
and regional) and (b) the respondent’s state of residence (Michigan or Virginia) on climate change policy support. We found
a modest relationship between state of residence and policy support, with Michigan residents less likely to support climate
change mitigation policies than residents of Virginia. The provision of information on the regional versus national level
of predicted impacts of climate change did not influence climate change policy support. 相似文献

This paper discusses methodological issues relevant to the calculation of historical responsibility of countries for climate
change (‘The Brazilian Proposal’). Using a simple representation of the climate system, the paper compares contributions to
climate change using different indicators: current radiative forcing, current GWP-weighted emissions, radiative forcing from
increased concentrations, cumulative GWP-weighted emissions, global-average surface-air temperature increase and two new indicators:
weighted concentrations (analogue to GWP-weighted emissions) and integrated temperature increase. Only the last two indicators
are at the same time ‘backward looking’ (take into account historical emissions), ‘backward discounting’ (early emissions
weigh less, depending on the decay in the atmosphere) and ‘forward looking’ (future effects of the emissions are considered)
and are comparable for all gases. Cumulative GWP-weighted emissions are simple to calculate but are not ‘backward discounting’.
‘Radiative forcing’ and ‘temperature increase’ are not ‘forward looking’. ‘Temperature increase’ discounts the emissions of
the last decade due to the slow response of the climate system. It therefore gives low weight to regions that have recently
significantly increased emissions. Results of the five different indicators are quite similar for large groups (but possibly
not for individual countries): industrialized countries contributed around 60% to today’s climate change, developing countries
around 40% (using the available data for fossil, industrial and forestry CO2, CH4 and N2O). The paper further argues including non-linearities of the climate system or using a simplified linear system is a political
choice. The paper also notes that results of contributions to climate change need to be interpreted with care: Countries that
developed early benefited economically, but have high historical emission, and countries developing at a later period can
profit from developments in other countries and are therefore likely to have a lower contribution to climate change. 相似文献

This paper reviews regional climate knowledge and vulnerability in the northern Mexico San Pedro River Basin, with a focus
on water quality, quantity, and management issues on the Mexican side of the border. A discussion based on the available literature
is supplemented by a survey assessing concerns about water and the quality and usability of climate and hydrologic information
available to water managers and communities. The surveys indicate that the central concern for urban residents is the lack
of reliable potable water due to frequent service breakdowns–with climate change and variability, specifically drought and
high temperatures, as contributing factors. Water managers desire appropriate meteorological and hydrologic information to
improve planning strategies, but access to this information remains limited. Considerable disagreement exists about who should
pay for previously free or low-cost water and wastewater treatment. Urban users have little incentive to conserve because
of the present flat, low rate and frustration with service. In rural areas, while a majority of ranchers recognize that variable
climate and water loss could increasingly jeopardize their lifestyle, they seldom use meteorological information in planning
or modify their water consumption. Climate vulnerability also includes potential for serious environmental health issues due
to the presence of heavy metals and organic contaminants in the San Pedro. 相似文献

Considering climatic uncertainties in management planning is a prerequisite for sustainable forest management (SFM). The aim
of the study was to evaluate climate change vulnerability of the current SFM strategy for commercial forests managed by the
Austrian Federal Forests. To that end vulnerability indicators were defined in a stakeholder process (selected indicators
were productivity, timber and carbon stocks, biodiversity, disturbances, a tree species’ position in fundamental niche space,
silvicultural flexibility and cost intensity) and their performance under climate change scenarios assessed with an ecosystem
model. Multi criteria analysis techniques were employed in a partial aggregation of indicators to locate forest stands on
a vulnerability surface. Results revealed high vulnerability particularly in the second half of the twenty-first century,
where 39.6% of the 164.550 ha study area were assessed highly vulnerable to climate change, indicating a strong decline in
the functions and services represented by the indicator system. Water-limited sites on calcareous bedrock were most negatively
affected whereas assessment units at higher altitudes responded predominately positive to climate warming. The presented approach,
transparently integrating multiple management objectives and allowing a quantitative comparison of vulnerabilities between
sites and management strategies, contributes to the development of operational and efficient climate change adaptation measures
in forest management. 相似文献

Subjective elements are an inevitable component of scientific advice on climate policies. Good practice warrants that the
level of assumption underlying subjective elements be parsimonious, that their effects on policy decisions be identified,
and that policy relevant variables be communicated with appropriate levels of precision. In the case of climate sensitivity,
the level of precision is intrinsically difficult to quantify. There is no ‘true’ value of climate sensitivity to be discovered.
Rather, best practice consists of the application of multiple methods to estimate the quantity. Best practice provides confidence
that some values of climate sensitivity are more likely than others. This lends support to the notion of weighting climate
sensitivity values, though the appropriate precision appears to be less than that implied by use of a probability density
function (pdf) and greater than that implied by use of a simple range. Use of both a pdf and a range in this case can provide
information about likely outcomes and possible extremes. 相似文献

Climate change will bring about a sea change in environmental conditions worldwide during the 21th century. In particular, most of the extreme events and natural disaster regimes prevailing today will be transformed, thus exposing innumerable natural and socio-economic systems to novel risks that will be difficult to cope with. This crucial component of vulnerability to anthropogenic interference with the climate system is analyzed using powerful pattern recognition methods from statistical physics. The analysis is of intermediate character, with respect to spatial scale and complexity level respectively, and therefore allows a rapid regional assessment for any area of interest. The approach is based on a comprehensive inventory of all those ecological and socioeconomic assets in a region that are significantly sensitive to extreme weather (and climate) events. Advanced cluster analysis techniques are then employed to derive from the inventory a set of thematic maps that succinctly summarize – and visualize – the differential vulnerabilities characteristic of the area in question. This information can prepare decision makers and the general public for the climate change hazards to be faced and facilitates a precautionary climate change risk management. The semiquantitative methodology described and applied here can be easily extended to other aspects of climate change assessment. 相似文献

In this article, we discuss how two interpretations of vulnerability in the climate change literature are manifestations of different discourses and framings of the climate change problem. The two differing interpretations, conceptualized here as ‘outcome vulnerability’ and ‘contextual vulnerability’, are linked respectively to a scientific framing and a human-security framing. Each framing prioritizes the production of different types of knowledge, and emphasizes different types of policy responses to climate change. Nevertheless, studies are seldom explicit about the interpretation that they use. We present a diagnostic tool for distinguishing the two interpretations of vulnerability and use this tool to illustrate the practical consequences that interpretations of vulnerability have for climate change policy and responses in Mozambique. We argue that because the two interpretations are rooted in different discourses and differ fundamentally in their conceptualization of the character and causes of vulnerability, they cannot be integrated into one common framework. Instead, it should be recognized that the two interpretations represent complementary approaches to the climate change issue. We point out that the human-security framing of climate change has been far less visible in formal, international scientific and policy debates, and addressing this imbalance would broaden the scope of adaptation policies. 相似文献

Reindeer husbandry represents a major land use in the Barents region, and has been predicted to be adversely affected by climate
change. This paper considers the likely response of reindeer husbandry to changes both in climate and in socio-economic circumstances
in the four countries of the Barents region from 1990 to 2080. Key natural factors include vegetation distribution, and a
range of meteorological variables including temperature, wind, snow cover and freezing of rivers. The potential impact of
these factors is evaluated quantitatively using the tolerable windows method, the results of which indicate a general but
spatially non-uniform decline in the suitability of the region for reindeer husbandry. Relevant socio-economic factors include
regional patterns of politics, management and knowledge. A focus on herders’ own perceptions of environmental change and flexibility
of response, derived particularly from study sites in Russia, suggests that models of vulnerability to climate change should
be tempered by paying greater attention to changes in socio-economic factors. When compared with the potential effect of changing
these socioeconomic factors, the vulnerability of reindeer husbandry to projected climate change appears to be comparatively
small. 相似文献

Unlike many other environmental problems, the terms used to describe the phenomenon of increasing atmospheric concentrations
of anthropogenic greenhouse gases are many, with multiple and sometimes conflicting meanings. Whether there are meaningful
distinctions in public perceptions of “global warming,” “climate change,” and “global climate change” has been a topic of
research over the past decade. This study examines public preferences for these terms based on respondent characteristics,
including climate change beliefs, political affiliation, and audience segment status derived from the “Global Warming’s Six
Americas” classification. Certainty of belief in global warming, political affiliation and audience segment status were found
to be the strongest predictors of preference, although “I have no preference” was the modal response. Global warming appears
to be a more polarizing term than climate change, preferred most by people already concerned about the issue, and least by
people who don’t believe climate change is occurring. Further research is needed to identify which of these two names promotes
the engagement of people across the spectrum of climate change beliefs in constructive dialogue about the issue. 相似文献

Vulnerability to hunger in Africa: A climate change perspective 总被引:1,自引:0,他引:1
Limitations of present assessments of climate change impacts on food supplies are addressed, and a new approach is proposed. This uses the concept of vulnerability to hunger as a point of departure. A typology of vulnerability indices is developed and several measures of vulnerability are explored using information from case studies reported in the literature and research coordinated by the author's research group. An initial synthesis of data about climate change and vulnerability to hunger is illustrated for Africa. 相似文献

Agricultural meteorologists are concerned with many operational aspects of the effects of climate on crop production, livestock,
and natural resource management. For them to continue to make a contribution to the economy of a country they must continually
sharpen their skills and remain updated on the latest available information. Training should include a variety of skills,
including transferable skills (e.g. communication, numeracy), professional skills (including cognitive skills) and information
technology skills. Problem-based learning can be used to promote critical thinking, decision making and analytical skills.
More use should be made of computer-aided learning for agricultural meteorologists’ in-service training. In particular, the
Internet or CDs could be used to disseminate specific recently developed techniques and applications to improve the understanding
of the variability in climate and its effect on agricultural production and natural resource management. Examples that can
address the vulnerability of farmers include crop–climate matching, the use of indices, crop modelling and risk assessment
together with seasonal outlooks. A strategy needs to be formulated to address these needs and implement changes in the education
and training of agricultural meteorologists. These training needs must be constantly updated to meet the changing demands
of new technology to cope with climate change and climate variability. 相似文献

California is home to some of the worst air quality in the nation and ninety percent of the state’s population lives in areas
that are out of attainment with at least one of the National Ambient Air Quality Standards. Increasing temperatures associated
with climate change will make meeting air quality standards more difficult. Under a changing climate, additional emission
reductions will be needed to achieve clean air standards. These additional emission reductions and associated costs are called
the “climate penalty.” Air quality planning is the process of assessing the emission reductions needed to meet air quality
standards and outlining the programs and policies that will be implemented to achieve these emission reductions. This paper
reviews the challenges that a changing climate will pose for air quality planning in California and identifies opportunities
for adaptation. While state air quality regulators in California are taking enormous strides to address global warming, less
work is happening at the regional, air district level. Air districts are the agencies responsible for developing air quality
improvement plans. An important first step for regional air quality regulators will be to quantify the climate penalty and
understand their region’s vulnerability to climate change. Limitations in regulatory authority could impede measures to improve
preparedness. Regional agencies will likely need to look to state and federal agencies for additional emission reductions. 相似文献

While it is generally asserted that those countries who have contributed least to anthropogenic climate change are most vulnerable to its adverse impacts some recently developed indices of vulnerability to climate change come to a different conclusion. Confirmation or rejection of this assertion is complicated by the lack of an agreed metric for measuring countries’ vulnerability to climate change and by conflicting interpretations of vulnerability. This paper presents a comprehensive semi-quantitative analysis of the disparity between countries’ responsibility for climate change, their capability to act and assist, and their vulnerability to climate change for four climate-sensitive sectors based on a broad range of disaggregated vulnerability indicators. This analysis finds a double inequity between responsibility and capability on the one hand and the vulnerability of food security, human health, and coastal populations on the other. This double inequity is robust across alternative indicator choices and interpretations of vulnerability. The main cause for the higher vulnerability of poor nations who have generally contributed little to climate change is their lower adaptive capacity. In addition, the biophysical sensitivity and socio-economic exposure of poor nations to climate impacts on food security and human health generally exceeds that of wealthier nations. No definite statement can be made on the inequity associated with climate impacts on water supply due to large uncertainties about future changes in regional water availability and to conflicting indicators of current water scarcity. The robust double inequity between responsibility and vulnerability for most climate-sensitive sectors strengthens the moral case for financial and technical assistance from those countries most responsible for climate change to those countries most vulnerable to its adverse impacts. However, the complex and geographically heterogeneous patterns of vulnerability factors for different climate-sensitive sectors suggest that the allocation of international adaptation funds to developing countries should be guided by sector-specific or hazard-specific criteria despite repeated requests from participants in international climate negotiations to develop a generic index of countries’ vulnerability to climate change. 相似文献

Sustaining agricultural production and food security in Southern Africa: an improved role for climate prediction? 总被引:1,自引:0,他引:1
Emma Archer Elijah Mukhala Sue Walker Maxx Dilley Kennedy Masamvu 《Climatic change》2007,83(3):287-300
Livelihoods and household food security in the Southern African region can be extremely vulnerable to the negative effects
of climate stress as shown by the 2002–2004 ‘complex emergency.’ Climate prediction may prove a valuable resource in mitigating
these effects. If climate prediction is applied successfully, it may be able to help guide responses in populations at risk
to reduce vulnerability to climate stress. The study presented here seeks to understand what would constitute an improved
role for climate prediction in contributing to sustaining agricultural production and food security in Southern Africa. Investigation
undertaken during the 2002/2003 rainy season under regional conditions of elevated disaster risk shows, however, that a number
of weaknesses and gaps persistently characterize climate information systems in the Southern African region, and constrain
such systems’ ability to benefit key sectors, particularly agriculture. The stakeholder identification of such gaps forms
the basis for distilling concrete recommendations to improve process and organizational efficiency. Such recommendations,
while developmental, should better enable institutions and stakeholders involved in climate prediction to fulfill their potential
in supporting development of successful adaptation strategies in populations and sectors at risk. 相似文献

This study was undertaken to assess the potential impacts of climate change on agriculture in the Sikasso region of southern
Mali, as part of an effort by the U.S. Agency for International Development (USAID) to integrate climate change adaptation
considerations into their development projects. The region is considered to be the breadbasket of Mali, providing a substantial
amount of the country’s food supplies as well as cotton for exchange earnings. The project had two components: modeling how
climate change could affect production of cereal and cash crops in southern Mali; and conducting a stakeholder-driven vulnerability
and adaptation assessment to identify potential options for addressing current and projected risks to agriculture from climate
change. Projected changes in crop yields were based on a previous analysis that was extended for the purposes of this study.
The projections suggested that the sensitivity of maize to changing weather conditions is relatively small (generally less
than 10% change) under both dry and wet scenarios in 2030 and 2060. White (Irish) potatoes, the primary cash crop, are the
most sensitive to changing weather conditions, with yields decreasing under both dry and wet conditions; yields could decrease
by about 25% by 2060. Stakeholder workshops, field interviews, and an expert analysis were used to assess current and future
climate-related vulnerability and to identify potential adaptation options. The main focus of the assessment was farmers in
a village of about 3,000 people in the Sikasso region that practiced a rice-potato rotation system typical to the region.
The farmers emphasized adaptation measures that require outside financial and technical assistance, for example installation
of a water gate that would retain more water in the inland valley and increase the water table to flood rice fields during
the rainy season and for furrow irrigation of potatoes during the dry season. Adaptations emphasized by both the farmers and
representatives of regional technical services were crop diversification and germplasm improvement; soil and water management;
access to equipment (plows, carts, oxen, and improved stoves); credit stockage villageois (CSV); and fertilizer. 相似文献

Assessments of adaptation in agriculture have evolved considerably from early, top-down, impact assessments. These early assessments,
internationally and in New Zealand, provided a limited view of ‘smart farmer’ adaptation. While impact assessment provides
some useful insights, experience with vulnerability and adaptation assessment provides a more appropriate foundation for understanding
and characterising practical smart farmer adaptation. Findings are presented from 8 years of engagement with farmers in eastern
regions of New Zealand. A comprehensive farm resilience picture has emerged from this work. This picture reflects a strong
belief from real-world smart farmers that there is sufficient knowledge and experience to adapt to climate change. Proactive
farmers are already reading multiple signals, including changes in climate, and are responding. The farm resilience picture
provides a foundation for exploring alternative adaptation options and pathways for agriculture. These are presented and discussed
in response to two proposed climate change scenarios, a high carbon world scenario and a rapidly decarbonising world scenario.
Knowledge intensive, low input systems are consistent with the resilience picture drawn from farmers. Such systems are also
consistent with a rapidly decarbonising world scenario and, it is argued, are likely to become increasingly attractive under
a high carbon world scenario. A smart farming approach, focused on resilience, provides the basis for development of a response
capacity, with potentially significant co-benefits in terms of adaptation and mitigation to climate change. Wider issues and
needs to support the further development of farm resilience, and more widely landscape or regional resilience, are identified
and discussed. It is apparent from this work that ongoing engagement with smart farmers, focused on resilience, can contribute
significantly to development of a coordinated ‘bottom up’ and ‘top down’ response capacity. Addressing the psychology of change
is a fundamental need to ensure wider engagement. 相似文献

Analysis of human adaptation to climate change should be based on realistic models of adaptive behaviour at the level of organisations and individuals. The paper sets out a framework for analysing adaptation to the direct and indirect impacts of climate change in business organisations with new evidence presented from empirical research into adaptation in nine case-study companies. It argues that adaptation to climate change has many similarities with processes of organisational learning. The paper suggests that business organisations face a number of obstacles in learning how to adapt to climate change impacts, especially in relation to the weakness and ambiguity of signals about climate change and the uncertainty about benefits flowing from adaptation measures. Organisations rarely adapt ‘autonomously’, since their adaptive behaviour is influenced by policy and market conditions, and draws on resources external to the organisation. The paper identifies four adaptation strategies that pattern organisational adaptive behaviour. 相似文献

Eminent climate scientists have come to consensus that human influences are significant contributors to modern global climate
change. This study examines coverage of anthropogenic climate change in United States (U.S.) network television news – ABC World News Tonight, CBS Evening News and NBC Nightly News – and focuses on the application of the journalistic norm of ‘balance’ in coverage from 1995 through 2004. This study also
examines CNN WorldView, CNN Wolf Blitzer Reports and CNN NewsNight as illustrations of cable news coverage. Through quantitative content analysis, results show that 70% of U.S. television
news segments have provided ‘balanced’ coverage regarding anthropogenic contributions to climate change vis-à-vis natural
radiative forcing, and there has been a significant difference between this television coverage and scientific consensus regarding
anthropogenic climate change from 1996 through 2004. Thus, by way of the institutionalized journalistic norm of balanced reporting,
United States television news coverage has perpetrated an informational bias by significantly diverging from the consensus
view in climate science that humans contribute to climate change. Troubles in translating this consensus in climate science
have led to the appearance of amplified uncertainty and debate, also then permeating public and policy discourse. 相似文献
