Seasonal climate forecasts (SCF) are key in predicting these conditions and guiding risk management in agriculture. However, low SCF adoption rates among smallholder farmers are due to factors like uncertainty and lack of understanding. In this study, we evaluated the benefits of SCF in predicting growing season conditions, and crop performance, and developing climate risk management strategies in Kongwa district, Tanzania. We used sea surface temperature anomalies (SSTa) from the Indian and Pacific Ocean regions to predict seasonal rainfall onset dates using the k-nearest neighbor model. Contrary to traditional approaches, the study established the use of rainfall onset dates as the criterion for predicting and describing growing period conditions. We then evaluated forecast skills and the profitability of using SCF in crop management with the Agricultural Production System sIMulator (APSIM) coupled with a simple bio-economic model. Our findings show that SSTa significantly influences rainfall variability and accurately predicts rainfall onset dates. Onset dates proved more effective than traditional methods in depicting key growing period characteristics, including rainfall variability and distribution. Including SCF in climate risk management proved beneficial for maize and sorghum production both agronomically and economically. Not using SCF posed a higher risk to crop production, with an 80% probability of yield losses, especially in late-onset seasons. We conclude that while SCF has potential benefits, improvements are needed in its generation and dissemination. Enhancing the network of extension agents could facilitate better understanding and adoption by smallholder farmers.</div></div>","PeriodicalId":54226,"journal":{"name":"Climate Risk Management","volume":"47 ","pages":"Article 100686"},"PeriodicalIF":4.8,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143168407","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aims to identify how climate change affects household dietary diversity and whether the impacts are consistent across different food groups. To examine the impact of climate change on dietary diversity in Afghanistan, a climate change proxy variable (temperature) was created at the district level by calculating the difference from its long-term mean. Meanwhile, the Household Dietary Diversity Score (HDDS) was obtained from three rounds of household survey data conducted between 2011 and 2017, which included information from 60,099 households. Negative binomial regression analysis reveals a positive association between climate change and HDDS. That is, higher temperatures would lead to the higher availability of diverse diets in Afghanistan. Interestingly, climate change appears to affect food groups heterogeneously. While staple food consumption frequency remains unaffected, non-staple food consumption increases with higher temperatures. The results remain consistent after incorporating precipitation and two lagged versions of temperature and precipitation into the model. Therefore, the climate adaptation policies of the government of Afghanistan should consider different policy implications for staple and non-staple foods. These findings have policy implications for achieving food security and climate change-related Sustainable Development Goals (SDGs) such as SDG 2 (zero hunger) and SDG 13 (climate action).</div></div>","PeriodicalId":54226,"journal":{"name":"Climate Risk Management","volume":"47 ","pages":"Article 100687"},"PeriodicalIF":4.8,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143168406","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Specifically, we use the Pooled Fractional Probit (PFP) estimator to develop regression models for crop diversification, analyzing 6625 households for 3 years and 74 districts for 9 years, using Rural Agriculture Living Survey (RALS) and Crop Forecast Survey (CFS) datasets, respectively. Simpson’s Diversity Index (SDI) of crops serves as the dependent variable and is consistently higher at the district level than at the household level, suggesting that aggregation at larger scales may mask localized monoculture vulnerabilities. Our findings reveal that both current and historical climate shocks significantly influence crop diversification decisions at both the household and district levels in Zambia. Heat stress and rainfall deficits during the planting season promote crop diversification, but their effects vary due to the diverse agroecological conditions and crop characteristics in different areas. Historical climate shocks prompt farmers to diversify as a long-term resilience strategy.

Our research focuses on Lloret de Mar, Catalonia, to examine the impacts of heatwaves in vulnerable households. We analyze the vulnerability and resilience of these households to extreme heat events and heatwaves by studying lived experiences identifying their coping strategies and the barriers they face. To gather data, we conducted 28 interviews and participatory mapping exercises with users of a food distribution center run by Caritas. Participants frequently reported experiences of extreme discomfort at home, describing symptoms such as exhaustion, suffocation, and excessive sweating, exacerbated by high humidity levels. The study found that participants have limited coping mechanisms, relying mainly on natural ventilation and fans. Some are constrained to staying at home due to economic challenges, with no opportunity to use vacation as a respite. The participatory mapping further revealed that these households are regularly exposed to heat during their daily activities. In the absence of effective municipal or collective adaptation strategies, vulnerable households remain entrapped in increasingly unlivable conditions.

Drawing on these results, we discuss five strategies that can help research projects collaborate, co-produce, and engage with CBOs. They include understanding the network to inform engagement, paying attention to differential impacts and justice, employing flexible planning to accommodate multiple goals and perspectives, focusing on information sharing to advance collaboration, exploring narratives of change to understand adaptation and maladaptation, and confronting the question of “what next.” This study informs how research can more effectively engage CBOs in climate adaptation studies, which, in turn, can contribute to building plans and systems that are better equipped to build resilience to compound extreme events.</div></div>","PeriodicalId":54226,"journal":{"name":"Climate Risk Management","volume":"47 ","pages":"Article 100693"},"PeriodicalIF":4.8,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143421041","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In Longyearbyen, Norway, in the High Arctic Svalbard archipelago, climatic changes presently occur at rates well in excess of global means, with corresponding changes to climate-related risks requiring new and improved risk governance strategies. Here, we present the results from a literature review investigating how recent advances in climate-related risk governance can help inform risk governance strategy development in Longyearbyen. The literature identified in our work indicates recent research into the governance of climate-related risks has focused to a large extent on flooding or landslides. Successful risk governance in the reviewed literature often included data collection of both environmental and social information and emphasized local, context-specific knowledge via bi-directional risk communication throughout the risk governance process. We identified knowledge gaps in the literature review. First, there is a missing societal safety perspective on climate changes and natural hazards: much of the identified literature views the climatic changes and natural hazards either through a physical process-based perspective rooted in the natural sciences, or focuses on physical mitigation measures, without considering the interaction of nature, technology, and society. Second, there is a lack of research on data collection and analysis strategies that combine the acquisition of local knowledge via a discourse-based approach with data and knowledge generated from sensors or physical models via a technical approach. Third, more research is required on uncertainty assessment and handling in the risk governance process. Fourth, there is missing consideration of short-term disaster handling approaches – especially in relation to relatively more frequent consideration of long-term climate adaptation strategies. Finally, as none of the reviewed works specifically addressed risk governance in an Arctic setting, we discuss how the results from this literature review and the proposed risk governance framework can help transfer knowledge to Longyearbyen’s context.

Best management practices (BMPs) can serve as adaptation strategies to negate the impact of climate change on sediment and total nitrogen (TN) loads. One major controversial issue in climate change adaptation studies is the highly uncertain nature of such changes. Previous studies have rarely focused on the combined impact of the uncertainty in climate change and watershed model parameters, which could be the main sources of uncertainty in climate change adaptation research. In this study, the effectiveness and resilience (defined as continued effectiveness under a changing climate) of BMPs in reducing sediment and TN loads were explored under future climate change in the Shanmei Reservoir watershed (SMW) of Southeast China. Climate change projections provided by 10 general circulation models (GCMs) under the SSP1-2.6, SSP2-4.5, SSP3-7.0, and SSP5-8.5 scenarios from 2031 to 2060 were applied in the Annualized Agricultural Nonpoint Source (AnnAGNPS) model to evaluate the effectiveness and resilience of 4 BMPs (riparian buffers (RB), no-tillage (NT), fertilization reduction (FR), and parallel terraces (PT)). The ensemble average of 10 GCMs and 10 behavior parameter groups were adopted to reduce the uncertainty resulting from the hydrological model parameters and GCMs. The results indicated that the average annual temperature and precipitation in the SMW will increase in the future. On a seasonal scale, the average temperature during all seasons will increase, and precipitation will decrease in summer and autumn but increase in spring and winter. The annual sediment and TN loads will decrease, but the loads in spring and winter will increase. BMPs could be effective as climate adaptation strategies for reducing sediment and TN loads under future climate conditions, with PT as the most effective option. Structural BMPs were more effective in reducing sediment and TN loads in spring and winter, whereas nonstructural BMPs were more effective in reducing loads in summer and autumn. BMPs were more resilient when future watershed runoff changes were slight or climate sensitivity was reduced, with higher BMP resilience in spring and winter than in summer and autumn. This study aimed to provide systematic references for watersheds through the implementation of BMPs for mitigating the effects of climate change and extending the boundaries of the AnnAGNPS model application.</p></div>","PeriodicalId":54226,"journal":{"name":"Climate Risk Management","volume":"44 ","pages":"Article 100612"},"PeriodicalIF":4.4,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2212096324000299/pdfft?md5=01cc36aeb1c544b4662a7eba91434b83&pid=1-s2.0-S2212096324000299-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140650457","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
