PurposeThis paper aims to inform the readers an overview of expected impacts of sea level rise (SLR) and climate change on rice crops area, yield and the urgent need to build climate responsive infrastructures to a coastal district, Alappuzha – a high-risk area which is already under mean sea level (MSL). This research carried out to understand the realities and impacts with respect to the exposures of rise in SLR and possible inundation extent of crop land. The extreme precipitation events have caused crop loss and damage, numerous casualties and enormous economic loss in this district during the recent past and project the likely impacts under anticipated climate change.Design/methodology/approachGlobal sea levels have already been risen noticeably as a result of climate change, and this trend is anticipated to continue.

PurposeThere is an urgent need to translate climate change awareness into tangible climate adaptation strategies. The built environment is identified as one of the kick-off points in making climate change adaptation as the built environment shares a dual-way relationship. While the built environment largely contributes to the climate change-triggering factors, it also becomes highly vulnerable in the face of climate change impacts. Tied up with the interconnectedness of the built environment processes and associated systems, the involvement of numerous stakeholders from different spectrums creates the need for a holistic and multi-stakeholder approach in developing climate response strategies for the built environment. Accordingly, this study aims to identify the roles and responsibilities of the different built environment stakeholders in climate change adaptation.Design/methodology/approachThe study consisted of a scoping review at the initial stage, contextualising studies based on secondary data, and semi-structured expert interviews in five different countries: the UK, Sweden, Malta, Spain and Sri Lanka. The paper summarises the findings of the individual country-level desk studies and 65 built environment stakeholder interviews representing national and local governments, communities, academia and research organisations, civil organisations, professional bodies and the private sector. The findings were validated through focus group discussions in two stakeholder seminars.FindingsThe findings summarised a set of key roles and sub-roles for each stakeholder category, considering the current status and needs. The national governments need to set a long-term vision, enabling multi-sector interventions while promoting investment and innovation in climate change adaptation. The local governments overlook local adaptation plans, while the community is responsible for decarbonising operations and practising adaptation at the local level. Civil organisations and professional bodies are the voice of the community, linking policy and practice. Academia and research are responsible for nurturing skills and new knowledge, and the private sector must contribute by adopting climate resilience into their business portfolio and corporate social responsibility.Research limitations/implicationsThis research is part of an Europe-Union-funded research project, Built Environment leArning for Climate Adaptation (BEACON), which aims to develop skills and competencies of the built environment professionals so that they will be adequately equipped to handle the adaptation process of the built environment needs to adapt in facing the climate change impacts.Originality/valueThe paper provides an in-depth analysis of the roles and responsibilities pertaining to each category of the different stakeholders in effectively adapting the built environment to withstand the climate change consequences.

目的迫切需要将气候变化意识转化为切实可行的气候适应战略。建筑环境被认为是适应气候变化的启动点之一,因为建筑环境具有双向关系。虽然建筑环境在很大程度上助长了气候变化的诱发因素,但面对气候变化的影响,它也变得非常脆弱。由于建筑环境过程和相关系统相互关联,因此需要众多不同领域的利益相关者参与进来,这就要求在制定建筑环境气候应对战略时采用整体和多利益相关者方法。因此,本研究旨在确定不同建筑环境利益相关者在气候变化适应中的角色和责任。本研究包括初始阶段的范围审查、基于二手数据的背景研究以及在五个不同国家(英国、瑞典、马耳他、西班牙和斯里兰卡)进行的半结构式专家访谈。本文总结了个别国家级案头研究和 65 个建筑环境利益相关者访谈的结果,这些利益相关者代表了国家和地方政府、社区、学术和研究组织、民间组织、专业机构和私营部门。在两次利益相关者研讨会上,通过焦点小组讨论对研究结果进行了验证。研究结果考虑到当前状况和需求,总结了每个利益相关者类别的一系列关键作用和次级作用。国家政府需要制定长期愿景,支持多部门干预,同时促进气候变化适应方面的投资和创新。地方政府忽视当地的适应计划,而社区则负责在地方层面实现低碳化运营和适应实践。民间组织和专业机构是社区的代言人,将政策与实践联系起来。本研究是欧盟资助的研究项目 "建筑环境适应气候(BEACON)"的一部分,该项目旨在培养建筑环境专业人员的技能和能力,使他们有足够的能力应对建筑环境的适应过程,以适应气候变化的影响。原创性/价值 本文深入分析了各类利益相关者在有效适应建筑环境以抵御气候变化后果方面的作用和责任。对每个利益相关者的作用和责任进行单独划分,有利于各方之间的合作与协调,并为建筑环境适应气候变化提供了一种更加全面的方法。

PurposeDisasters are occurring worldwide, and Sri Lanka has also become a victim of multiple disasters. Though there is a disaster management mechanism from the national level to the local level in Sri Lanka, several gaps are identified in pre- and postdisaster management activities. Among them, the responsibilities of local-level stakeholders in flood management activities are not performing at a satisfactory level. Therefore, the flood damage from the previous events was too great. Accordingly, the purpose of this study is to assess the roles, responsibilities and performance of stakeholders involved in local-level flood risk management activities.Design/methodology/approachThe Deduru Oya basin in Sri Lanka was selected as the study area. The study hypothesized that “ineffective roles, responsibilities and performance of local level stakeholders have weakened the flood risk management in the Deduru Oya basin.” The stratified random sampling method selected the sample (n = 425) from the flood-vulnerable population. Primary data were collected through a questionnaire survey, key informant interviews and field observations. Secondary data were collected from reports, work plans, journal papers and published maps. Descriptive data analysis methods and thematic data analysis methods were used in the study.FindingsAbout 69% of the respondents state that they are not satisfied with the involvement of government agencies in local-level flood risk management activities, while 10% of the respondents state that they are satisfied. The thematic analysis reveals several gaps, such as the lack of reservations in the Deduru Oya, improper land use practices, no inundation areas are identified and mapped out and the effects of illegal sand mining in the Deduru Oya. In addition to that, the lack of legal power vested in local governments in disaster management and the weaknesses of current legislation on flood risk management are the other major courses of local-level ineffectiveness.Research limitations/implicationsThe current research was limited to studying the involvement of local-level stakeholders in flood risk management, but the involvement of subnational and national-level stakeholders should be studied in future research.Originality/valueThis paper examines the involvement of local-level stakeholders in flood risk management. The results of the study confirm that the roles and responsibilities of local-level stakeholders are not well-defined and mandated, and therefore, the performance of stakeholders involved is minimal. Therefore, the results highlight the need for a well-established community-based flood risk management mechanism.
目的全世界都在发生灾害,斯里兰卡也成为多种灾害的受害者。虽然斯里兰卡从国家一级到地方一级都有灾害管理机制,但在灾前和灾后管理活动方面仍存在一些差距。其中,地方一级利益攸关方在洪灾管理活动中的职责履行情况不尽人意。因此,前几次事件造成的洪灾损失过大。因此,本研究旨在评估参与地方一级洪水风险管理活动的利益相关者的作用、责任和绩效。研究假设:"地方一级利益相关者的作用、责任和表现不力,削弱了 Deduru Oya 流域的洪水风险管理"。分层随机抽样法从易受洪水影响的人口中选取样本(n = 425)。主要数据通过问卷调查、关键信息提供者访谈和实地观察收集。二手数据则从报告、工作计划、期刊论文和出版的地图中收集。研究采用了描述性数据分析方法和专题数据分析方法。研究结果约 69% 的受访者表示,他们对政府机构参与地方一级洪水风险管理活动的情况不满意,10% 的受访者表示满意。专题分析揭示了几个差距,如 Deduru Oya 缺乏保留地、土地使用不当、未确定淹没区并绘制淹没区地图以及 Deduru Oya 非法采砂的影响。除此以外,地方政府在灾害管理方面缺乏法定权力以及有关洪水风险管理的现行立法存在缺陷,也是导致地方一级工作效率低下的主要原因。研究局限性/影响目前的研究仅限于研究地方一级利益相关者参与洪水风险管理的情况,但在今后的研究中应研究国家以下一级和国家一级利益相关者的参与情况。研究结果证实,地方一级利益相关者的作用和责任没有得到明确界定和授权,因此,利益相关者的参与绩效微乎其微。因此,研究结果凸显了建立完善的社区洪水风险管理机制的必要性。

PurposeThe purpose of this paper is to explore the application of smart systems and emerging technologies for disaster risk management (DRM) in Nepal. This delves into specific technologies, including advanced connection and communication technologies, AI, big data analytics, autonomous vehicles and advanced robotics, examining their capabilities and potential contributions to DRM. Further, it discusses the possibility of implementing these technologies in Nepal, considering the existing policies and regulations, as well as the challenges that need to be addressed for successful integration.Design/methodology/approachFor this review journal series of search strategy for identifying relevant journals, the initial examination of results, a manual assessment, geographical refinement, establishment of criteria for the final selection, quality assessment and data management, along with a discussion of limitations. Before delving into the relevant literature within the field of research interest, the authors identified guiding keywords. Further, the authors refined the list by filtering for articles specifically related to Nepal, resulting in a final selection. The final selection of these 95 articles was based on their direct relevance to the research topics and their specific connection in the context of Nepal.FindingsThe way technology is used to reduce disaster risk has changed significantly in Nepal over the past few years.

PurposeThis study aims to analyze the policies and strategies used by governmental organizations to address the impacts of climate change in informal neighborhoods, kampungs, such as Bukit Duri and Melayu in Jakarta, Indonesia, focusing on canal and river flooding mitigation and infrastructure development. The research examines the displacement of residents due to the demolition of informal settlements along riverbanks, the role of different governmental organizations and the implications of these policies on affected communities.Design/methodology/approachThis study uses the theoretical framework of environmental injustice to evaluate the strategies used by the Indonesian Government to address climate change adaptation in Jakarta, with a specific focus on the problem of flooding and its impact on displacement. By analyzing the history and outcomes of flood mitigation policies, this paper assesses the government’s strategies related to infrastructure, evacuation and socialization. In doing so, the study examines the social impact of these policies on affected communities. Furthermore, social listening and media analysis of Twitter data and various news outlets are conducted to gain insights into the living conditions and experiences of displaced residents in two public housing projects.FindingsThe study revealed the challenges faced by the government in implementing policies for climate change adaptation and flood mitigation in Jakarta, including a lack of community engagement with residents of the Kampungs in the decision-making process for relocation. Despite government efforts and providing low-cost apartments (rusuwana), the analysis sheds light on the various forms of injustice that result from the government’s approach to climate change adaptation in Jakarta.Originality/valueThis study examines social justice issues in Jakarta’s informal neighborhoods and explores locally driven efforts vs government-mandated policies for managing natural hazards and adapting to climate change.

PurposeIn an urban environment, different types of actors (individuals, households, community groups, institutions, governmental organizations, nongovernmental organizations (NGO), community-based organizations (CBO) and public and private organizations, etc.) play critical roles in enhancing urban resilience to adapt to the impacts of climate change. To identify and prioritize aspects of climate resilience planning, this study aims to examine the potential impacts of climate change on diverse urban systems and evaluate the capacities of various actors to adapt to climatic stress.Design/methodology/approachThis research selects Mongla, a coastal as well as port town in south-western Bangladesh that faces climate risks including frequent cyclones, storm surges and salinity intrusion due to sea-level and temperature rise, as reported in the National Climate Vulnerability Index 2018. This research uses the methodology proposed by ICLEI South Asia’s Climate Resilient Cities Action Plan and accesses different urban actors’ adaptive capacity for contributing to enhancing climate resilience based on three broad characteristics: the capacity to organize and respond, availability of resources and access to information. The cumulative scores of these characteristics aid in determining the climate adaptive capacity of each urban actor.FindingsThe identified 53 actors are grouped into four categories: government (local and national); international/local NGOs, CBOs and associations; community representatives and private sectors and groups and individuals. The group of NGOs, CBOs and associations has a higher overall adaptive potential than all other actor groups, according to the study. When it comes to practicing adaptive capacity, government institutions are in the second-highest position. But, the Khulna development authority, the government agency that is in charge of overseeing all forms of urban development, scored poorly on all fragile urban systems. However, the performance of the fourth group of urban actors is very subpar when it comes to adapting to climatic stress, which emphasizes the need for focused interventions.Research limitations/implicationsVariations in adaptive capacities to climate change across different actors are particularly useful for targeting actors with lower levels of climate adaptive capacities in Mongla town.Originality/valueThis paper particularly addresses the research gap in assessing the adapting capacity of urban actors in Mongla port-town. Policymakers and practitioners can create and carry out targeted interventions that address the particular needs and concerns of vulnerable actors by making use of the insights obtained from this kind of study, thereby assisting in the development of climate resilience in any urban area.
目的 在城市环境中,不同类型的参与者(个人、家庭、社区团体、机构、政府组织、非政府组织(NGO)、社区组织(CBO)以及公共和私人组织等)在提高城市适应气候变化影响的复原力方面发挥着至关重要的作用。为了确定气候适应性规划的各个方面并确定其优先次序,本研究旨在考察气候变化对不同城市系统的潜在影响,并评估不同参与者适应气候压力的能力。本研究选择了孟加拉西南部的沿海以及港口城市勐拉,根据《2018 年国家气候脆弱性指数》的报告,勐拉面临着气候风险,包括频繁的气旋、风暴潮以及海平面和气温上升导致的盐度入侵。本研究采用了国际地方环境倡议理事会南亚气候韧性城市行动计划提出的方法,根据组织和应对能力、资源可用性和信息获取这三大特征,获取不同城市行动者的适应能力,以促进提高气候韧性。这些特征的累积得分有助于确定每个城市行动者的气候适应能力。研究结果将确定的 53 个行动者分为四类:政府(地方和国家);国际/地方非政府组织、社区组织和协会;社区代表和私营部门以及团体和个人。研究显示,非政府组织、社区组织和协会的总体适应潜力高于其他所有参与者群体。在实践适应能力方面,政府机构位居第二。但是,负责监督各种形式城市发展的政府机构库尔纳发展局在所有脆弱城市系统方面的得分都很低。然而,在适应气候压力方面,第四类城市参与者的表现却很不理想,这就强调了进行重点干预的必要性。研究局限性/影响不同参与者对气候变化的适应能力存在差异,这对于针对勐拉镇气候适应能力水平较低的参与者特别有用。政策制定者和实践者可利用此类研究获得的见解,制定并实施有针对性的干预措施,以满足弱势参与者的特殊需求和关切,从而帮助任何城市地区发展气候适应能力。

PurposeThe potential for massive economic growth exists in Samarinda City due to the intensification of activities in built-up areas. This suggests the potential for increased urban disease in the relocation of Indonesia’s new capital city to a location adjacent to Samarinda. One of the most striking impacts is the urban heat island (UHI). The increase in this phenomenon can be addressed effectively and efficiently through the provision and arrangement of appropriate vegetation-based actions. Therefore, this study aims to identify priority areas of green open space (GOS) based on UHI levels. In addition, this study also aims to present alternative mitigation measures to reduce the risk of disasters due to UHI.Design/methodology/approachA mixed-method approach was used in this research, involving an initial land surface temperature analysis to identify the UHI class. This analysis was complemented by quantitative spatial analyses, such as scoring, overlay and intersect methods, to determine the priority level class and the typology of GOS priority. A qualitative analysis was also conducted through data triangulation or comparison methods, such as examining existing land use, GOS priority maps and spatial plan policies.FindingsThe findings show that the total UHI area in Samarinda City was 6,936.4 ha in 2019 and is divided into three classifications. In Class 1, the UHI area is very dominant, reaching 87% of the total area. Meanwhile, the main results identified two priority classes of GOS in Samarinda, namely, the medium and high categories with an area of 960.43 ha and 113.57 ha, respectively. The results also showed that there were 17 typologies associated with five alternative mitigation measures: green industry, greening parking lots, improving urban green infrastructure and buildings, urban greening and mining restoration.Research limitations/implicationsSpecific to assessing UHI, image data were available only in medium spatial resolution, leading to a consequence of detailed accuracy. In addition, since the determination of mitigation considered local policies, the method should be used in other locations requiring adjustments to existing regulations, specifically those related to spatial planning.Originality/valueThis study makes a significant contribution to the understanding of the UHI phenomenon in Indonesia, especially in the urban areas of Kalimantan Island. In addition, the study presents new insights into alternative mitigation actions to reduce the risk of UHI. Innovatively, this study introduces a typology of regions associated with appropriate alternative mitigation actions, making it an important achievement for the first time in the context of this study.
目的由于建筑密集区的活动加剧,沙马林达市存在着大规模经济增长的潜力。这表明,在印度尼西亚新首都搬迁到毗邻三马林达的地点时,城市疾病有可能增加。最显著的影响之一是城市热岛(UHI)。通过提供和安排适当的植被行动,可以有效和高效地解决这一现象的增加。因此,本研究旨在根据 UHI 水平确定绿色开放空间(GOS)的优先区域。此外,本研究还旨在提出可供选择的缓解措施,以降低因 UHI 而导致的灾害风险。设计/方法/方法本研究采用了混合方法,包括初步的地表温度分析,以确定 UHI 等级。这项分析还辅以定量空间分析,如评分法、叠加法和交叉法,以确定优先等级和全球观测系统优先类型。此外,还通过数据三角测量或比较方法进行了定性分析,如研究现有土地利用情况、全球观测系统优先级地图和空间规划政策。在第 1 类中,UHI 面积非常大,占总面积的 87%。同时,主要结果还确定了两个优先级别的全球观测系统,即中级和高级,面积分别为 960.43 公顷和 113.57 公顷。结果还显示,有 17 种类型与五种可供选择的缓解措施相关:绿色工业、绿化停车场、改善城市绿色基础设施和建筑、城市绿化和矿山恢复。此外,由于确定缓解措施时考虑了地方政策,因此该方法应适用于其他需要调整现有法规(特别是与空间规划相关的法规)的地方。此外,该研究还为采取其他缓解行动以降低 UHI 风险提供了新的见解。本研究创新性地引入了与适当的替代缓解行动相关的区域类型学,这在本研究中尚属首次,是一项重要成就。

PurposeBuilt environments are highly vulnerable to climatic disasters such as extreme floods, droughts and storms. Inaccurate decisions in adopting emerging construction technologies can result in missed opportunities to improve the resilience of built environments. Therefore, understanding the effectiveness of emerging construction technologies in improving built environment resilience can help in making better strategic decisions at the national and organizational levels. This study aims to evaluate the effectiveness of Construction 4.0 technologies in improving built environment resilience.Design/methodology/approachA list of Construction 4.0 technologies was adopted from a national strategic plan. Then, the data were collected using the fuzzy technique for order preference by similarity to ideal solution technique from selected built environment experts to determine the relative effectiveness of Construction 4.0 technologies in improving built environment resilience.FindingsSix Construction 4.0 technologies are critical in improving built environment resilience (in rank order): building information modeling, autonomous construction, advanced building materials, big data and predictive analytics, internet of Things and prefabrication and modular construction. In addition, adopting Construction 4.0 technologies collectively is crucial, as moderate to strong connections exist among the technologies in improving built environment resilience.Originality/valueTo the best of the authors’ knowledge, this is one of the first papers that evaluate the effectiveness of Construction 4.0 technologies in improving built environment resilience. Industry professionals, researchers and policymakers can use the study findings to make well-informed decisions on selecting Construction 4.0 technologies that improve built environment resilience to climatic disasters.
目的 建筑环境极易受到极端洪水、干旱和风暴等气候灾害的影响。在采用新兴建筑技术时,如果决策不准确,就会错失提高建筑环境复原力的机会。因此,了解新兴建筑技术在提高建筑环境复原力方面的有效性有助于在国家和组织层面做出更好的战略决策。本研究旨在评估建筑 4.0 技术在提高建筑环境复原力方面的有效性。研究结果六项 "建筑 4.0 "技术对提高建筑环境复原力至关重要(按排名顺序):建筑信息建模、自主施工、先进建筑材料、大数据和预测分析、物联网以及预制和模块化施工。此外,集体采用 "建筑 4.0 "技术也至关重要,因为这些技术之间在提高建筑环境复原力方面存在着中度到高度的联系。行业专业人士、研究人员和政策制定者可以利用研究结果做出明智决策,选择建筑 4.0 技术来提高建筑环境抵御气候灾害的能力。
