Heritage Resilience and Identity: Lesson from Trabocchi Coast about Climate Change Adaptation Strategies

Climate change and land use are major drivers of environmental and socioeconomic transformations in landscapes and in coastal areas. The objective of this study was to present an interdisciplinary and participatory research methodology for analysing the evolutionary process of a coastal case study, the Trabocchi Coast in the Abruzzo Region (Italy), from multiple perspectives, including climate change, technological history, conservation protocols, and social function. The goal was to assess the resilience of these coastal structures, i.e., their ability to cope and adapt to changes while maintaining their identity and recognition. The adopted approach combined qualitative and quantitative data from the meteorological analyses, literature review, and field investigations involving a participatory workshop, from which a significant portion of the analysed results presented here emerged. The results indicate that the Trabocchi Coast has undergone significant changes in recent decades, posing a serious threat to cultural heritage due to climate change (sea-level rise, coastal erosion, storms, flooding and salinisation), changes in use and mass tourism. However, these changes have also presented challenges and opportunities for coastal development, stimulating diverse resilient responses from local communities, ranging from resistance to innovation. The paper discusses the factors that may make the Trabocchi Coast a model of resilience considering these changes. This is supported by the role of local institutions as guarantors of the cultural heritage value of the trabocchi in that specific landscape context, as evidenced by the approval of the “Costa dei Trabocchi Special Territorial Project” by the Abruzzo Region in 2023.

Climate Change Adaptation Strategies and Its Impact on Household Vulnerability to Food Insecurity: A Micro-Level Evidence from Southwest Ethiopia

Smallholder farmers in Ethiopia face increasing challenges from climate change and variability, which threaten their food security and livelihoods. This study examines how adopting single and combined climate change adaptation practices affects their vulnerability to food insecurity in Bench Maji Zone, southwest Ethiopia. Through multistage sampling, data were gathered from 390 rural households in four climate-prone districts. The study examines the impacts resulting from both individual and combined implementations of adaptation techniques. These techniques encompass crop management practices, soil and water conservation measures, and livelihood portfolio diversification strategies. The study employed the multinomial endogenous treatment effect regression model to address selection bias and endogeneity resulting from various sources of heterogeneity, whether observed or unobserved. The results show that farmers who adopted adaptation practices were less vulnerable to food insecurity than those who did not. The study also finds that adopting multiple practices has a more significant impact than adopting single practices. Our findings suggest that implementing climate change adaptation strategies can increase the resilience of smallholder farmers in the study area and decrease their vulnerability to food insecurity. The study recommends supporting farmers in adopting these strategies through research and development, information dissemination, and collaborations among farmers, researchers, and extension services.

Coupled Climate–Environment–Society–Ecosystem Resilience Coordination Analytical Study—A Case Study of Zhejiang Province

The aim of this paper is to evaluate the coupled coordination degree of climate, environmental, socio-economic, and ecosystem resilience in Zhejiang Province from 2010 to 2022 and to propose optimization strategies. With the increasing impact of global climate change, the need to explore the construction of resilient cities and sustainable development models has become increasingly pressing. Assessing the coupled coordination among climate, environment, socio-economic, and ecosystem resilience aids in suggesting more precise and effective social and ecological recovery strategies in the context of climate change. Zhejiang Province, serving as a model for China’s urbanization development, demonstrates a balance between the natural environment, economic growth, and social development but still suffers from ecological and environmental pollution problems. In this study, an evaluation system was constructed utilizing the entropy weight method (EWM), and the coupled coordination among climate, environmental, socio-economic, and ecosystem resilience in Zhejiang Province was empirically analyzed over the period from 2010 to 2022. The results show that (1) the climatic-environmental, socio-economic, and ecological subsystems of cities in Zhejiang Province generally show an upward trend, despite fluctuations over different periods. (2) The climatic-environmental-social-ecological system resilience of the cities in Zhejiang Province increased as a whole, and six cities (Hangzhou: 0.805, Quzhou: 0.811, Huzhou: 0.827, Taizhou: 0.829, Wenzhou: 0.856, and Jinhua: 0.857) reached the “well-coordinated” level by 2022; however, the coupling coordination of Jiaxing City and Lishui City decreased from good to intermediate coordination. (3) The coupled coordination degree of climatic-environmental-social-ecological system resilience generally stagnated in each city during 2020–2022. Thus, the climate change adaptation strategy proposed in this study aims to enhance urban adaptive capacity to climate change impacts by controlling pollutant emissions, restoring ecosystems, optimizing industrial structures, and designing urban green spaces.

Risk reduction through managed retreat? Investigating enabling conditions and assessing resettlement effects on community resilience in Metro Manila

Abstract. Managed retreat, a key strategy in climate change adaptation for areas with high hazard exposure, raises concerns due to its disruptive nature, vulnerability issues and overall risk in the new location. On-site upgrading or near-site resettlement is seen as more appropriate and effective compared to a relocation far from the former place of living. However, these conclusions often refer to only a very limited set of empirical case studies or do not sufficiently consider different context conditions and phases in resettlement. Against this background, this paper examines the conditions and factors contributing to community resilience of different resettlement projects in Metro Manila. In this urban agglomeration reside an estimated 500 000 informal households, with more than 100 000 occupying high-risk areas. In light of the already realized and anticipated climate change effects, this precarious living situation exposes families, already socio-economically vulnerable, to an increased risk of flooding. The response of the Philippine government to the vexing problem of informal dwellers has been large-scale resettlement from coasts, rivers and creeks to state-owned sites at urban fringes. However, only very few resettlement projects could be realized as in-city projects close to the original living space. The study employs a sequential mixed-method approach, integrating a large-scale quantitative household survey and focus group discussions (FGDs) for a robust comparison of resettlement types. Further, it reveals community-defined enabling factors for managed retreat as climate change adaptation strategy. Results indicate minor variations in well-being conditions between in-city and off-city resettlement, challenging the expected impact of a more urban setting on resilience. Instead, essential prerequisites for resettlement involve reduced hazard exposure, secure tenure and safety from crime. Beyond these essential conditions, social cohesion and institutional support systems emerge as significant influencers for the successful establishment of well-functioning new settlements. With this findings, the study contributes to the expanding body of literature on managed retreat, offering a comprehensive evaluation based on extensive datasets and providing entry points for the improvement of retreat as a climate change adaptation strategy.

Additionally, this paper outlines key strategies for climate change adaptation (CCA) in ports. The results of this research offer insights into sustainable practices and collaborative efforts to confront climate change challenges effectively. These findings have the potential to significantly improve maritime policy and ship management strategies.

POULTRY FARMERS’ KNOWLEDGE LEVEL OF CLIMATE CHANGE ADAPTATION STRATEGIES IN IMO STATE, NIGERIA

This study investigated poultry farmers’ knowledge level of climate change adaptation strategies in Imo State, Nigeria. The specific objectives identified the various sources of agricultural information available to the farmers on climate change in the study area, examined the knowledge level of the poultry farmers on climate change adaptation strategies; ascertained various climate change adaptation strategies employed by poultry farmers in the area. A multi-staged sampling technique was employed in sampling 120 poultry farmers that took part in the survey. A set of questionnaires was used to get responses from farmers. Both descriptive and inferential statistics were used to analyze the data. Findings from the study showed that fellow farmers were the major source of information on agriculture for 90% of the poultry farmers. while good housing system (100%), adequate extensive poultry management system (100%) and immediate vaccination of birds (100%) ranked high on the table of climate change adaptation strategies that poultry farmers utilize. Also, with a grand mean of 2.52, above the benchmark mean of 2.00, the poultry producers demonstrated a high level of knowledge regarding measures for adapting to climate change. The hypothesis result indicated a strong relationship between the farmers' sources of information on strategies for adapting to climate change and their level of knowledge with these tactics. The study came to the conclusion that poultry farmers had a high level of knowledge about different climate change adaptation strategies, primarily from other farmers. As a result, it was recommended that the government increase the availability of extension services to poultry farmers so that they can obtain scientifically verified and tried-and-true information on adaptation strategies for increased and sustainable knowledge in the study area.

Impact of common shade tree species on microclimate and cocoa growth in agroforestry systems in Ghana

Climate change is a growing threat to agriculture globally, with most substantial impacts expected in tropical smallholder systems such as cocoa farms in West Africa. Cocoa agroforestry is widely believed to enhance resilience to climatic extremes due to protection and a favourable microclimate under the shade trees. Morphological traits of many locally used shade tree species and their specific contribution to microclimate for climate-resilient cocoa production remain unclear. Therefore, aboveground morphology and sub canopy microclimate of eight common shade tree species were investigated in cocoa agroforestry systems in the Ahafo region, Ghana. Additionally, the growth of cocoa trees in three different distance zones to the shade tree stem was measured. The eight different shade tree species exhibited considerable variation in their impact on microclimate and cocoa growth. M. indica and M. excelsa allowed lowest light transmission, with the highest microclimatic buffering effect, i.e., reducing vapour pressure deficit and daily fluctuations of temperature and relative humidity. Cocoa trees around M. lucida and F. capensis were the highest in growth, characterized by height and stem diameter. However, a universally superior shade tree species could not be identified implying the need for shade tree diversity allowing various microclimatic conditions within an agroforestry system to spread risk of climate extremes. Cocoa tree growth was more affected by distance to the shade tree than by shade tree species, resulting in enhanced growth with distance to the stem. These findings provide a better understanding of species-related differences on cocoa growing conditions and climate change adaptation strategies.

Exploring Historical Patterns of Urban Migration in Pakistan: Origins and Drivers

This study explores the historical patterns and antecedents of urban migration in Pakistan, focusing on the interaction of demographic, economic, and environmental factors. Economic factors like wage disparities, job opportunities, and service access significantly influence migration. Rapid urbanization and inadequate infrastructure make it difficult to house and integrate migrants, exacerbating existing housing, transportation, and healthcare issues. The study advocates for evidence-based policymaking, utilizing descriptive analysis, focusing on sustainable urban development, migrant welfare, and inclusive growth. This study has identified various economic, demographic, and environmental factors that have contributed to rapid urbanization, such as migration for healthcare, education, and services. Still, low economic growth and rapid population growth lead to higher unemployment, low wages, natural disasters, and political instability. It emphasizes prioritizing rural development, improving urban infrastructure, and increasing disaster resilience. Proposals call for regional cooperation and climate change adaptation strategies to address cross-border migration challenges.

Assessment of behavioural response to climate forecasts and climate change adaptation by small-holder farmers in Nambale sub-county of Busia county, Kenya

Under climate change and unpredictable rainfall variability, rainfed agriculture has often been characterised with high degree of crop failure, especially when rainfall seasons portray anomalies in rainfall onsets and cessation. This study sought to establish the level of utilisation of climate forecasts and behavioural response to such products by the smallholder farmers in Nambale, Busia, Kenya. A total of 30 subsistence farmers were interviewed. Results showed that about 4 in every 5 farmers are largely unconscious of climate change and its effects and did not adhere to the climatic forecasts, instead, farming was subjected to the year-to-year routine practices, dependent on the traditional approaches. About 60% of the farmers lacked knowledge of climate change and believed that crop failure is beyond human understanding. 100% of the farmers planted maize in the two main planting seasons of March-April-May (MAM) and August-September-October (ASO), with about 86.7% of them least practicing crop diversification or intercropping. Furthermore, climate change adaptation interventions such as planting of early maturing, drought resistant crops and crop irrigation were unlikely among the farmers. Crop performance on an experimental farm established by the Nambale Science Place-Centre for Community Engagement on Climate Risk Interpretation (NSP-CCECRI), showed potential for enhanced farm production if farming activities are adhered to timely utilisation of climate forecasts. Based on these findings, and considering limited climate change adaptation strategies, there is need for sensitising smallholder farmers in enhancing knowledge on climate change and adaptation for enhanced food security, building community climate change resilience and alleviating poverty levels.

Climate change and heat stress resilient outdoor workers: findings from systematic literature review

PurposeGlobal warming has led to an increase in the number and intensity of extreme heat events, posing a significant threat to the health and safety of workers, especially those working outdoors, as they often have limited access to cooling strategies. The present systematic literature review (a) summarizes the current knowledge on the impacts of climate change on outdoor workers, (b) provides historical background on this issue, (c) explores factors that reduce and increase thermal stress resilience, (d) discusses the heat mitigation strategies, and (e) provides an overview of existing policy and legal frameworks on occupational heat exposure among outdoor workers.Materials and methodsIn this systematic review, we searched scientific databases including Scopus (N = 855), Web of Science (N = 828), and PubMed (N = 202). Additionally, we identified relevant studies on climate change and heat-stress control measures through Google Scholar (N = 116) using specific search terms. In total, we monitored 2001 articles pertaining to worker populations (men = 2921; women = 627) in various outdoor climate conditions across 14 countries. After full-text assessment, 55 studies were selected for inclusion, and finally, 29 eligible papers were included for data extraction.ResultsFailure to implement effective control strategies for outdoor workers will result in decreased resilience to thermal stress. The findings underscore a lack of awareness regarding certain adaptation strategies and interventions aimed at preventing and enhancing resilience to the impact of climate change on heat stress prevalence among workers in outdoor tropical and subtropical environments. However, attractive alternative solutions from the aspects of economic and ecological sustainability in the overall assessment of heat stress resilience can be referred to acclimatization, shading, optimized clothing properties and planned breaks.ConclusionThe integration of climate change adaptation strategies into occupational health programs can enhance occupational heat resilience among outdoor workers. Conducting cost-benefit evaluations of health and safety measures for thermal stress adaptation strategies among outdoor workers is crucial for professionals and policymakers in low- and middle-income tropical and subtropical countries. In this respect, complementary measures targeting hydration, work-rest regimes, ventilated garments, self-pacing, and mechanization can be adopted to protect outdoor workers. Risk management strategies, adaptive measures, heat risk awareness, practical interventions, training programs, and protective policies should be implemented in hot-dry and hot-humid climates to boost the tolerance and resilience of outdoor workers.

Determinants of climate change adaptation strategies and intensity of use; micro level evidence from crop farmers in Kenya

Climate change and its negative impacts pose a threat to crop production in Kenya. However, climate change adaptation strategies have the potential to address the challenges faced by crop farmers. Despite this, there is limited literature to inform policy on the best interventions to help farmers deal with climate issues. This study assessed the determinants of climate change adaptation strategies and the intensity of their use among 723 crop farmers in Busia County, Kenya, selected through a multistage sampling technique. Data were collected using a structured questionnaire and analyzed using principal component analysis (PCA), multinomial logit regression, and the ordered probit model. The climate change adaptation strategies were categorized into crop diversity, cover crops, use of drought-resistant crops, and irrigation. According to the results, the factors contributing to the uptake of the different adaptation strategies were age, household size, access to credit, training access, off-farm income, group membership, frequency of receiving climate change information, and extension services. The major factors influencing the uptake of multiple climate change adaptation strategies were access to credit and off-farm income. The study shows that certain adaptation strategies, such as using cover crops, do not require credit and offer an important option in an environment with limited resources. On the other hand, adaptation measures such as irrigation demand financial resources for farmers to implement them, highlighting the importance of information and awareness in adopting adaptation strategies and the supportive role of financial resources, particularly for adopting multiple strategies. Therefore, this study suggests implementing policies and interventions that encompass knowledge-based strategies such as extension services, training, climate change education, group participation, and financial mechanisms like income generation activities and access to credit. These integrated strategies will enable farmers to adopt various climate change adaptation methods for sustainable crop production.

DAIRY FARMERS' VIEWS ON OVERCOMING BARRIERS TO ADOPTING CLIMATE CHANGE ADAPTATION STRATEGIES

This study investigates the challenges inhibiting dairy farmers in South Gujarat from adopting climate change adaptation strategies and presents their perspectives on overcoming these constraints. Data were collected from 280 dairy farmers who were selected through multistage random sampling method in seven districts of South Gujarat. Survey findings revealed predominant issues: Communication participation, social engagement, and key farm-related factors significantly correlated with dairy farmers' adaptation strategies, while certain demographic and economic factors showed significant relationships at different probability levels. Non-significant correlations were found for age, gender, education, and other variables, suggesting nuanced influences that may require further exploration.86.77% cited inadequate technical guidance for livestock practices as the primary barrier, followed by 75.00% experiencing the unavailability of critical adaptation inputs. Financial constraints (67.85%) and limited access to timely weather forecasts (63.57%) were also significant hurdles. Reasons for non-adoption varied with 79.28% attributing it to insufficient resources and 72.50% believing climate change was exaggerated. Conversely, 51.78% sought innovative dairy farming to engage rural youth. The suggestions provided by farmers highlighted urgent needs: establishing low-cost weather forecasting systems (87.85%) and regular technical guidance visits (82.14%). Financial aid (72.50%) and awareness about livestock insurance schemes (60.71%) were stressed, alongside training in climate mitigation practices (59.28%).These findings underscore the multifaceted challenges faced by dairy farmers and offer a clear direction for policymakers and stakeholders. Implementing the suggested solutions could empower the farming community in adopting resilient climate adaptation strategies in South Gujarat reason.

Nexus between Indigenous Knowledge Systems and Adaptation to Climate Change Strategies by Farmers in Kajiado County, Kenya

Indigenous knowledge (IK) has played an important role in adaptation to climate change in traditional agricultural communities. These approaches have been shown to be more effective when integrated with scientifically developed strategies. In this study, a perception survey questionnaire was used to find out whether there is a nexus between IK systems and the uptake of modern Climate Change Adaptation Strategies (CCAS) among farmers in Kajiado County, Kenya. A mixed research approach that involved the use of household questionnaire surveys, key informant interviews, focus group discussions (FGD), and observations was used to obtain data. The two theories, namely the Situated Learning Theory (SLT) and the Theory of Planned Behavior (TPB), formed the basis for illustrating the relationship between variables, while the Model of Private Proactive Adaptation to Climate Change (MPPACC) was the key theoretical model employed. A total of 382 small-scale rural household representatives randomly selected from 3 Kajiado sub-counties were the principal respondents. The key informants included officers in the departments of agriculture, environment, meteorology, trade, and industry, as well as local administration and village elders. Statistical tools such as chi-square, correlation, and binary logistic regression analysis were used to determine associations. Thematic analysis of data collected from key informants and focus group discussions (FGD) was conducted to triangulate the survey results. Farmers' awareness of climate change, risk perceptions of impacts, existing locally developed approaches to climate change adaptation, and perceptions of CCAS were the main areas of investigation. The majority of farmers (85%) indicated that prolonged drought was the main extreme event that affected their farming activities. Of the indicators observed, drought (X2 = 13.861, p =.000) was perceived as the greatest risk associated with climate change to their agricultural productivity. Their IK adaptation strategies resulted from their interactions with the effects of drought on their livelihoods over the years. Farmers who were nomadic (IK practitioners) were not willing to apply for CCAS. For example, they were 72% less likely to increase their irrigated cropped area and 79% less likely to increase the number of better livestock breeds. Among the CCAS approaches, water resource management was the only preferred strategy. This particular finding shows that climate change policies can be easily adopted by indigenous farming communities if they are developed around an issue that matches their socio-ecological priorities. Without taking into account the prevailing social, cultural, and geo-environmental context of specific communities, the adoption of CCAS by farmers would be significantly affected. The study recommends that integrating indigenous agricultural knowledge into climate change adaptation policies enhances community resilience. Aligning adaptation strategies with local responses enriches farmer knowledge and boosts resilience against climate change impacts. Effective climate change adaptation plans should incorporate local weather prediction, environmental conservation, and proven community-based strategies, especially in water resource management for arid and semi-arid pastoralist communities.

Climate Change Adaptation Strategies among Coastal Community

Using seven themes of adaptability strategies drawn from existing literature, this study examines the strategies for adaptation among the Bajau community in Lok Nunuk to cope with the impacts of climate change in the area. Questionnaires were distributed to 60 household heads, and descriptive statistics were used to analyze the data. The four obvious adaptation strategies identified in this study are social-related activities, physical infrastructure, technology-assisted, and government and organization support. There needs to be more than adaptation strategies to improve income among the people; they must be integrated into broader socioeconomic development programs and environment management levels.

Forecasting urban temperatures through crowdsourced data from Citizen Weather Stations

This work explores the potential of using crowdsourced data from Citizen Weather Stations (CWS) to forecast urban temperatures. Five case studies were selected (Madrid, London, Rome, Paris and Berlin), using data from the manufacturer Netatmo to gather the hourly temperatures of the years 2021 and 2022 for 776 CWS. A quality-control process was implemented to enhance data accuracy, and heat maps were generated. Multiple linear regression models were created for each CWS and month using only reference weather data as input, resulting in the development of accurate models (RMSE lower than 1.5 °C) for an average of 374 CWS. Then, reference weather predictions were used on the 2nd of April 2023 to forecast the hourly temperatures of those CWS for the period from the 3rd to the 9th of April (168 h). The outcomes showed that accurate CWS data and precise prediction models for the reference weather are crucial to improve the accuracy of the forecasts using crowdsourced data. The study demonstrates the potential benefits of using CWS data and simple models to forecast urban temperatures in a cost-efficient way even 168 h ahead, with implications for various sectors such as urban planning, energy consumptions, health impacts, or climate change adaptation strategies.

Integrating Climate Change Adaptation Strategies into Urban Policies for Sustainable City Resilience: Barriers and Solutions in the Central African City of N’Djaména

Climate change has become a serious threat to human life. This study aims to reveal the face of climate policies and the integration of urban adaptation into urban planning policies in the city of N’Djaména. To achieve this, we adopted a methodology combining both quantitative and qualitative approaches. Surveys of key informants were used to gather information on how to achieve the objectives set. The results show that key informants believe that climate policies have not met the expectations of the city’s citizens in terms of effectiveness and positive impacts. These players assume that urban policy planning does not take urban adaptation into account. The four categories of barriers hindering the integration of urban adaptation and its implementation relate to a lack of information and knowledge, political ill will, and organization and constraints linked to the mobilization and availability of resources. This study suggests the sharing of information, knowledge, and communication involving all stakeholders in N’Djaména’s urban development, the organization of the city’s state and municipal structures, the involvement and support of political authorities, greater access to financing, and the establishment of professional networks of expertise as catalysts for success.

Exploring combined adaptation strategies to improve crop yield and smallholder farmers’ welfare

ABSTRACT This study investigates whether combinations of climate change adaptation strategies are associated with improved yield and smallholder farmers’ welfare, using a random sample of 200 maize producers in Benin. It employs an extended regression model to address the selection bias and endogeneity issues. Furthermore, as a robustness check, a multinomial endogenous switching regression model is also estimated. Results indicate that tree planting and the use of improved variety are the single strategies that increase yield. However, when combined with other strategies, the effects decrease for tree planting while increasing for the use of improved variety. With regard to the welfare equation, the only improved variety is the single strategy that increases food expenditure per capita, and the effect increases when combined with other strategies. Overall, the results reveal that the use of improved variety is the single strategy that increases both yield and smallholder farmers’ welfare, and combined with other strategies, the effect increases. These findings suggest that the adoption of combined adaptation strategies is important for ensuring smallholder farmers’ welfare.
