    The methods currently used to monitor and model lakes were developed when weather conditions were very different to what they are today. Most are based on samples collected at weekly or fortnightly intervals and cannot quantify the effects of short-term, more extreme, variations in the weather. In this article, the author presents some examples to show the importance of developing new monitoring methods using case studies from a number of lakes in the English Lake District. The impact of year-to-year changes and short-term changes on the dynamics of of lakes are highlighted

No consensus on the uncertainty of climate change, and different interests make difficulties in selecting priorities. Decision-making methodologies used for climate change adaptation should be flexible as priorities vary greatly depending on stakeholder composition or adaptation options changes. Meanwhile, multi-criteria decision-making (MCDM), is used to evaluate objects with various aspects, distinguishes between characteristics of options through conflicting indicators. TOPSIS (Technique for Order Preference by Similarity to Ideal Solution), one of the MCDM methods, evaluates the closeness of a hypothetical optimal alternative. By using this method, it is possible to reflect the personal characteristics of the respondents as much as possible, have less problems of ranking reversal, and have the advantage of judging the difference/similarity between alternatives, which can be a useful evaluation method for climate adaptation planning. In this study, expert group including municipalities and civic organizations were formed as a governance, and trustworthy adaptation policy priorities were derived via the evaluation results of the governance. A total of 65 experts participated in the questionnaire, and specifically, the governments and local government officials participating in the decision-making process, academic researchers who derive and interpret scientific results, and general citizens participated in the decision-making process. Most of the survey participants consisted of experts with over 10 years of experience in climate change adaptation management. Since different priority results can be generated for each group using TOPSIS, the method provides flexible priority, not one best priority. This method will allow decision-makers to expand their choices not only at the national level but also at the local level by adjusting the settings to suit the region. Priority results were presented for the 21 adaptation options derived for the water management sector, and the results are interpreted as relative closeness values. This study confirmed that selecting priorities in the adaptation requires a prioritizing method that can function flexibly according to the needs of decision makers. It also suggested how assessment indicators should be constructed appropriate for climate change adaptation and evaluation of adaptation options. From within-sector adaptation to external effects of climate change, indicators have been constructed to reflect how urgent it is in terms of policy feasibility. As a result of the survey, the priority of drought strategies such as Industrial, agricultural water demand management, Groundwater resource management, and Expansion of sewage reuse was high in the water management sector, followed by flood and water ecosystem strategies such as Build flood safety system at development stage and Water safety plan. While the results produced are only an example, the reliability and validity of the process can be improved by referring to these results in the decision-making process. It can be helpful in the planning process in that uncertain information can be assessed with limited resources, and the consistency of the process can be provided, and it can be used as a more useful way to link weighting methods with scientific data, such as impact assessment results in the future.κΈ°ν›„λ³€ν™” μ μ‘κ³„νšμ˜ 수립 μ‹œμ—λŠ” κΈ°ν›„λ³€ν™” 영ν–₯ λ˜λŠ” 취약성에 λŒ€ν•œ μ’…ν•© 뢄석 결과에 따라 각 λΆ€λ¬Έμ˜ μ •μ±… μš°μ„ μˆœμœ„λ₯Ό μ„€μ •ν•΄μ•Ό ν•œλ‹€. 기후변화에 λŒ€ν•œ λΆˆν™•μ‹€μ„±, 그리고 μ„œλ‘œ λ‹€λ₯Έ μ΄ν•΄κ΄€κ³„λ‘œ μΈν•˜μ—¬ μš°μ„ μˆœμœ„λ₯Ό κ²°μ •ν•˜λŠ” 것은 쉽지 μ•Šμ€ μž‘μ—…μ΄λ‹€. λ”ν•˜μ—¬ κΈ°ν›„λ³€ν™” 적응에 μ‚¬μš©λ˜κΈ° μœ„ν•œ μ˜μ‚¬κ²°μ • 방식은 μ΄ν•΄κ΄€κ³„μžμ˜ ꡬ성 λ³€ν™” ν˜Ήμ€ μ •μ±… 변경에 μœ μ—°ν•˜κ²Œ λŒ€μ²˜ν•  수 μžˆμ–΄μ•Ό ν•œλ‹€. ν•œνŽΈ, λ‹€κΈ°μ€€ μ˜μ‚¬κ²°μ • 방법둠(Multi-criteria decision-making; MCDM)은 μ—¬λŸ¬ μΈ‘λ©΄μ—μ„œ λŒ€μƒμ„ ν‰κ°€ν•˜κ³  μ„œλ‘œ λ‹€λ₯Έ μ„±κ²©μ˜ μ§€ν‘œλ₯Ό ν†΅ν•΄μ„œ 평가 λŒ€μƒμ„ κ΅¬λ³„ν•˜λŠ” 데에 μ‚¬μš©λœλ‹€.

    Delivering organisational adaptation through legislative mechanisms: Evidence from the Adaptation Reporting Power (Climate Change Act 2008)

    Get PDF
    There is increasing recognition that organisations, particularly in key infrastructure sectors, are potentially vulnerable to climate change and extreme weather events, and require organisational responses to ensure they are resilient and adaptive. However, detailed evidence of how adaptation is facilitated, implemented and reported, particularly through legislative mechanisms is lacking. The United Kingdom Climate Change Act (2008), introduced the Adaptation Reporting Power, enabling the Government to direct so-called reporting authorities to report their climate change risks and adaptation plans. We describe the authors' unique role and experience supporting the Department for Environment, Food and Rural Affairs (Defra) during the Adaptation Reporting Power's first round. An evaluation framework, used to review the adaptation reports, is presented alongside evidence on how the process provides new insights into adaptation activities and triggered organisational change in 78% of reporting authorities, including the embedding of climate risk and adaptation issues. The role of legislative mechanisms and risk-based approaches in driving and delivering adaptation is discussed alongside future research needs, including the development of organisational maturity models to determine resilient and well adapting organisations. The Adaptation Reporting Power process provides a basis for similar initiatives in other countries, although a clear engagement strategy to ensure buy-in to the process and research on its long-term legacy, including the potential merits of voluntary approaches, is required

    The environmental impact of climate change adaptation on land use and water quality

    Get PDF
    Encouraging adaptation is an essential aspect of the policy response to climate change1. Adaptation seeks to reduce the harmful consequences and harness any beneficial opportunities arising from the changing climate. However, given that human activities are the main cause of environmental transformations worldwide2, it follows that adaptation itself also has the potential to generate further pressures, creating new threats for both local and global ecosystems. From this perspective, policies designed to encourage adaptation may conflict with regulation aimed at preserving or enhancing environmental quality. This aspect of adaptation has received relatively little consideration in either policy design or academic debate. To highlight this issue, we analyse the trade-offs between two fundamental ecosystem services that will be impacted by climate change: provisioning services derived from agriculture and regulating services in the form of freshwater quality. Results indicate that climate adaptation in the farming sector will generate fundamental changes in river water quality. In some areas, policies that encourage adaptation are expected to be in conflict with existing regulations aimed at improving freshwater ecosystems. These findings illustrate the importance of anticipating the wider impacts of human adaptation to climate change when designing environmental policies
